上述的每一个对象类别，都可以看作是用于对取流行为管控的一个维度。通过管控多个对象类别的关联对象来实施对取流行为的管控，可以实现对取流行为的多维度管控。Each of the above object categories can be regarded as a dimension used to control the fetching behavior. By controlling the associated objects of multiple object categories to implement the management and control of the fetching behavior, the multi-dimensional management and control of the fetching behavior can be realized.

然而，随着视频流媒体行业的发展，业务种类增多，仅针对总取流路数来管控取流行为，无法满足取流行为管控需求，容易影响各类业务的运行效果。However, with the development of the video streaming media industry, the types of services have increased.

有鉴于此，本申请实施例提供了一种取流控制方法，本申请实施例取流控制方法应用于图1的网络架构。在本申请实施例取流控制方法中，第一视频流媒体服务平台接收来自第一客户端设备的取流请求。其中，取流请求用于请求获取目标监控点的目标业务流。然后，第一视频流媒体服务平台响应于取流请求，根据管控策略确定是否执行针对目标监控点的取流行为，以获取目标业务流，并向第一客户端设备发送目标业务流。其中，管控策略用于组合管控目标关联对象中每个关联对象针对目标监控点的取流行为，目标关联对象与获取目标监控点的目标业务流相关联。这样一来，除了总取流路数之外，第一视频流媒体服务平台还能够组合关联对象，针对组合的不同关联对象进行取流行为管控，增加取流行为的管控维度，使得取流行为的管控粒度更细，有助于提升业务运行效果，避免管控维度单一所导致的业务运行效果差的问题。In view of this, an embodiment of the present application provides a flow control method, and the flow control method according to the embodiment of the present application is applied to the network architecture of FIG. 1 . In the streaming control method according to the embodiment of the present application, the first video streaming media service platform receives a streaming request from the first client device. The flow retrieval request is used to request to obtain the target service flow of the target monitoring point. Then, the first video streaming media service platform, in response to the stream fetch request, determines whether to execute the stream fetch behavior for the target monitoring point according to the management and control policy, so as to obtain the target service stream, and send the target service stream to the first client device. The management and control strategy is used to combine the fetching behavior of each associated object in the management and control target associated objects with respect to the target monitoring point, and the target associated object is associated with the target business flow for obtaining the target monitoring point. In this way, in addition to the total number of fetched streams, the first video streaming service platform can also combine associated objects, and manage and control the fetching behavior for different associated objects in the combination. The granularity of management and control is finer, which helps to improve the effect of business operation and avoids the problem of poor business operation effect caused by a single management and control dimension.

In addition, downloading can also be described as streaming-recording download, as shown in Table 1.

需要说明的是，以上仅以预览、回放和下载业务为例，对目标业务进行介绍，目标业务也可以有其他类型的业务，本申请实施例对此不作限定。It should be noted that the above only takes the preview, playback, and download services as examples to introduce the target service, and the target service may also have other types of services, which are not limited in this embodiment of the present application.

其中，目标监控点的介绍如下：一个监控点上可以部署有一个云台。云台用于支撑图像采集设备，如摄像机。对于某一监控点而言，该监控点上的图像采集设备所采集视频流中的一部分，或所采集的全部视频流，属于第一客户端设备意图获取的目标业务流。Among them, the introduction of the target monitoring point is as follows: a monitoring point can be deployed with a PTZ. The PTZ is used to support image acquisition equipment such as cameras. For a certain monitoring point, a part of the video streams collected by the image acquisition device on the monitoring point, or all the video streams collected belong to the target service stream that the first client device intends to acquire.

示例性的，再以图3b为例，第一客户端设备向第一视频流媒体服务平台的VNSC组件发送第一取流请求。Exemplarily, again taking FIG. 3b as an example, the first client device sends a first streaming request to the VNSC component of the first video streaming media service platform.

S302、第一视频流媒体服务平台根据管控策略a对第一取流请求进行校验，以得到第一取流请求的校验结果。S302 , the first video streaming media service platform verifies the first streaming request according to the management and control policy a, so as to obtain a verification result of the first streaming request.

其中，管控策略a用于组合管控关联对象a中每个关联对象针对目标监控点的取流行为。针对管控策略a，组合管控的关联对象可以记为目标关联对象1。示例性的，指示目标关联对象1针对目标监控点允许的取流路数，或指示目标关联对象1针对目标监控点允许的取流路数不受限，或指示目标关联对象1针对目标监控点允许的取流路数为零。示例性的，参见表1，表1示出了多种管控策略：Among them, the management and control strategy a is used to combine and control the fetching behavior of each associated object in the associated object a with respect to the target monitoring point. For the management and control strategy a, the associated object of combined management and control can be recorded as the target associated object 1. Exemplarily, instruct the target associated object 1 to allow the number of flow paths for the target monitoring point, or instruct the target associated object 1 to allow the number of flow paths for the target monitoring point to be unlimited, or instruct the target associated object 1 for the target monitoring point. The number of allowed access paths is zero. For example, see Table 1, which shows various management and control strategies:

表1Table 1

在表1中，关联对象有7种，包括联网系统、应用、客户端设备、用户、用户组、边缘系统和边缘网关。取流业务有3种类型的子业务，包括预览、回放和下载。业务权限有3种，包括开、关和不限流。其中，业务权限是开，可以理解为，允许该关联对象获取针对某个类型的业务流，但取流路数受限。其中，取流路数的上限值，可以由变量所在列的取值确定。业务权限是关，可以理解为，不允许该关联对象获取针对某个类型的业务流。业务权限是不限流，可以理解为，允许该关联对象获取针对某个类型的业务流，且取流路数不受限。示例性的，以应用所在行为例，某一应用针对预览的业务权限可以是开，且取流路数受限。某一应用针对预览的业务权限也可以是关，不允许该应用针对预览业务取流。某一应用针对预览的业务权限还可以是不限流，允许该应用针对预览业务取流，且取流不受限。其他关联对象和其他业务的业务权限介绍可以参见表1，此处不再一一赘述。In Table 1, there are seven types of associated objects, including networking systems, applications, client devices, users, user groups, edge systems, and edge gateways. The streaming service has 3 types of sub-services, including preview, playback and download. There are 3 types of business permissions, including on, off and unlimited current. Among them, the business authority is open, which can be understood as allowing the associated object to obtain a certain type of business flow, but the number of flow channels is limited. The upper limit of the number of flow paths can be determined by the value of the column where the variable is located. The business authority is off, which means that the associated object is not allowed to obtain a business flow for a certain type. The business authority is unlimited, which can be understood as allowing the associated object to obtain a certain type of business flow, and the number of flow channels is not limited. Exemplarily, taking the row where the application is located as an example, the service permission of a certain application for preview may be enabled, and the number of access channels is limited. The service permission of an application for preview can also be off, and the application is not allowed to obtain traffic for preview service. The service permission of an application for the preview service may also be unlimited, allowing the application to obtain the stream for the preview service, and the access to the stream is not restricted. For the introduction of other associated objects and business rights of other services, please refer to Table 1, which will not be repeated here.

应理解，在目标关联对象1实现为表1中的关联对象，目标业务实现为表1中的业务的情况下，管控策略a可以此类推，不再一一赘述。It should be understood that in the case where the target associated object 1 is implemented as the associated object in Table 1, and the target service is implemented as the service in Table 1, the management and control policy a can be deduced by analogy, and will not be described in detail.

下面，以管控策略a指示取流路数为例，对目标关联对象1进行介绍：Below, the target associated object 1 is introduced by taking the number of flow paths indicated by the management and control policy a as an example:

例如，以目标关联对象1包括用户和第一客户端设备为例，在目标业务是预览的情况下，管控策略a指示用户和第一客户端设备分别针对预览允许获取视频流的取流路数。在目标业务是回放的情况下，管控策略a指示用户和第一客户端设备分别针对回放允许获取视频流的取流路数。在目标业务是下载的情况下，管控策略a指示用户和第一客户端设备分别针对下载允许获取视频流的取流路数。For example, taking the target associated object 1 including the user and the first client device as an example, in the case where the target service is a preview, the management and control policy a instructs the user and the first client device to obtain the number of video streams allowed to obtain the video stream respectively for the preview . In the case where the target service is playback, the management and control policy a instructs the user and the first client device to respectively allow the number of video streams to be obtained for playback. In the case where the target service is downloading, the management and control policy a indicates that the user and the first client device are respectively allowed to obtain the number of video streams for downloading.

再如，以目标关联对象1包括用户组、第一视频流媒体服务平台和第一客户端设备为例，在目标业务是预览的情况下，管控策略a指示用户组、第一视频流媒体服务平台和第一客户端设备分别针对预览允许获取视频流的取流路数。在目标业务是回放的情况下，管控策略a指示用户组、第一视频流媒体服务平台和第一客户端设备分别针对回放允许获取视频流的取流路数。在目标业务是下载的情况下，管控策略a指示用户组、第一视频流媒体服务平台和第一客户端设备分别针对下载允许获取视频流的取流路数。For another example, take the target associated object 1 including the user group, the first video streaming service platform and the first client device as an example, in the case that the target service is a preview, the management and control policy a indicates the user group, the first video streaming service The platform and the first client device are respectively allowed to obtain the number of video streams for the preview. In the case where the target service is playback, the management and control policy a instructs the user group, the first video streaming media service platform, and the first client device to respectively allow the number of video streams to be obtained for playback. In the case where the target service is download, the management and control policy a indicates the number of streams that the user group, the first video streaming media service platform, and the first client device are allowed to acquire the video stream respectively for downloading.

应理解，目标关联对象1也可以有其他组合，如针对目标业务流关联的关联对象a中，选取两个或两个以上的关联对象，来构成组合，如用户组和第一视频流媒体服务平台，第一视频流媒体服务平台和第一客户端设备等，本申请实施例对目标关联对象1的组合方式不作限定。It should be understood that the target associated object 1 may also have other combinations. For example, in the associated object a associated with the target service flow, two or more associated objects are selected to form a combination, such as the user group and the first video streaming service. The platform, the first video streaming media service platform, the first client device, etc., the embodiment of the present application does not limit the combination of the target associated object 1 .

下面，以目标业务流包括n1路预览视频流为例，对S302的实现过程进行介绍：Below, the implementation process of S302 is introduced by taking the target service stream including n1 preview video streams as an example:

示例1，第一取流请求指示用户甲获取n1路预览视频流。此种情况下，第一视频流媒体服务平台采用的管控策略a至少指示：用户甲针对预览允许的最大取流路数为N1。在原有已请求路数n0的基础上，再新增请求n1路预览视频流后，若n0+n1之和小于或等于N1，则第一取流请求的校验结果指示满足管控策略a的要求。反之，若n0+n1之和大于N1，则第一取流请求的校验结果指示不满足管控策略a的要求。Example 1, the first stream request instructs user A to obtain n1 preview video streams. In this case, the management and control policy a adopted by the first video streaming media service platform at least indicates that the maximum number of access streams allowed by user A for preview is N1. On the basis of the original number of requested channels n0, after adding a new request for n1 channels of preview video streams, if the sum of n0+n1 is less than or equal to N1, the verification result of the first streaming request indicates that the requirements of the management and control policy a are met. . Conversely, if the sum of n0+n1 is greater than N1, the verification result of the first flow fetch request indicates that the requirements of the management and control policy a are not met.

示例2，第一取流请求指示用户组1获取n1路预览视频流。此种情况下，第一视频流媒体服务平台采用的管控策略a至少指示：用户组1针对预览允许的最大取流路数为N1。在原有已请求路数n0的基础上，再新增请求n1路预览视频流后，若n0+n1之和小于或等于N1，则第一取流请求的校验结果指示满足管控策略a的要求。反之，若n0+n1之和大于N1，则第一取流请求的校验结果指示不满足管控策略a的要求。Example 2, the first streaming request instructs user group 1 to acquire n1 preview video streams. In this case, the management and control policy a adopted by the first video streaming media service platform at least indicates that the maximum number of access streams allowed by the user group 1 for preview is N1. On the basis of the original number of requested channels n0, after adding a new request for n1 channels of preview video streams, if the sum of n0+n1 is less than or equal to N1, the verification result of the first streaming request indicates that the requirements of the management and control policy a are met. . Conversely, if the sum of n0+n1 is greater than N1, the verification result of the first flow fetch request indicates that the requirements of the management and control policy a are not met.

示例3，第一取流请求指示第一客户端设备获取n1路预览视频流。此种情况下，第一视频流媒体服务平台采用的管控策略a至少指示：第一客户端设备针对预览允许的最大取流路数为N1。在原有已请求路数n0的基础上，再新增请求n1路预览视频流后，若n0+n1之和小于或等于N1，则第一取流请求的校验结果指示满足管控策略a的要求。反之，若n0+n1之和大于N1，则第一取流请求的校验结果指示不满足管控策略a的要求。Example 3, the first streaming request instructs the first client device to acquire n1 channels of preview video streams. In this case, the management and control policy a adopted by the first video streaming media service platform at least indicates that the maximum number of access streams allowed by the first client device for preview is N1. On the basis of the original number of requested channels n0, after adding a new request for n1 channels of preview video streams, if the sum of n0+n1 is less than or equal to N1, the verification result of the first streaming request indicates that the requirements of the management and control policy a are met. . Conversely, if the sum of n0+n1 is greater than N1, the verification result of the first flow fetch request indicates that the requirements of the management and control policy a are not met.

应理解，上述示例1到示例3中，n0为正整数。上述示例1到示例3仅示出了单个关联对象的处理过程。而管控策略a用于组合管控关联对象a中每个关联对象的取流行为，所以，S302包括上述示例的组合。例如，目标关联对象1包括用户和第一客户端设备，则S302包括上述示例1和示例3，且示例1和示例3均满足管控策略a的要求，才确定第一取流请求的校验结果为：满足管控策略a的要求。反之，若示例1和示例3中有一项满足管控策略a的要求，则确定第一取流请求的校验结果为：不满足管控策略a的要求。再如，目标关联对象1包括用户组和第一客户端设备，则S302包括上述示例2和示例3，且示例2和示例3均满足管控策略a的要求，才确定第一取流请求的校验结果为：满足管控策略a的要求。反之，若示例2和示例3中有一项满足管控策略a的要求，则确定第一取流请求的校验结果为：不满足管控策略a的要求。当然，目标关联对象1也可以有其他组合，则S302的具体实现过程也会发生变化，可以上述举例进行类推，此处不再一一赘述。It should be understood that in the above examples 1 to 3, n0 is a positive integer. The above examples 1 to 3 only show the processing of a single associated object. The management and control policy a is used to combine and control the retrieval behavior of each associated object in the associated object a, so S302 includes a combination of the above examples. For example, if the target associated object 1 includes the user and the first client device, then S302 includes the above-mentioned example 1 and example 3, and both the example 1 and example 3 meet the requirements of the management and control policy a, and then the verification result of the first streaming request is determined. To: meet the requirements of management and control strategy a. Conversely, if one of Examples 1 and 3 satisfies the requirements of the management and control policy a, it is determined that the verification result of the first flow acquisition request is: the requirements of the management and control policy a are not met. For another example, if the target associated object 1 includes the user group and the first client device, then S302 includes the above-mentioned example 2 and example 3, and both the example 2 and the example 3 meet the requirements of the management and control strategy a, so that the verification of the first flow request is determined. The test result is: meet the requirements of management and control strategy a. Conversely, if one of Examples 2 and 3 satisfies the requirements of the management and control policy a, it is determined that the verification result of the first flow fetch request is: the requirements of the management and control policy a are not met. Of course, the target associated object 1 may also have other combinations, and the specific implementation process of S302 will also change, and analogies can be made by the above examples, which will not be repeated here.

需要说明的是，在上述N1的取值为零的情况下，可以理解为，管控策略a指示不允许目标关联对象1针对上述目标监控点的取流行为。在上述N1的取值为无穷大的情况下，可以理解为，管控策略a指示目标关联对象1针对目标监控点允许的取流路数不受限。It should be noted that, in the case where the value of the above N1 is zero, it can be understood that the management and control policy a indicates that the target associated object 1 is not allowed to take the behavior of the above target monitoring point. In the case where the value of N1 is infinite, it can be understood that the management and control policy a indicates that the target associated object 1 allows an unlimited number of access paths for the target monitoring point.

示例性的，以图3b为例，第一视频流媒体服务平台的VNSC组件根据第一取流请求，向第一客户端设备反馈短链接。相应的，第一客户端设备接收来自VNSC组件的短链接。其中，短链接指示了目标业务流的媒体服务端口、取流协议、取流路数等信息。第一客户端设备向第一视频流媒体服务平台的媒体组件发送请求消息a。其中，请求消息a包括上述短链接，请求消息a请求获取长链接，且请求消息a请求获取的长链接与上述短链接对应。在第一视频流媒体服务平台中，媒体组件向VNSC组件发送请求消息b。相应的，VNSC组件接收来自媒体组件的请求消息b。其中，请求消息b包括上述短链接，请求消息b请求获取长链接，且请求消息b请求获取的长链接与上述短链接对应。VNSC组件进行校验，以得到第一取流请求的校验结果。其中，VNSC组件得到的校验结果可以指示成功或失败。其中，成功，可以理解为，满足管控策略a的要求。失败，可以理解为，不满足管控策略a的要求。Exemplarily, taking FIG. 3b as an example, the VNSC component of the first video streaming media service platform feeds back a short link to the first client device according to the first streaming request. Accordingly, the first client device receives the short link from the VNSC component. The short link indicates information such as the media service port of the target service stream, the stream fetching protocol, and the number of fetching paths. The first client device sends a request message a to the media component of the first video streaming service platform. The request message a includes the above short link, the request message a requests to obtain a long link, and the long link requested by the request message a corresponds to the above short link. In the first video streaming service platform, the media component sends a request message b to the VNSC component. Correspondingly, the VNSC component receives the request message b from the media component. The request message b includes the above short link, the request message b requests to obtain a long link, and the long link requested by the request message b corresponds to the above short link. The VNSC component performs verification to obtain the verification result of the first stream fetching request. The verification result obtained by the VNSC component may indicate success or failure. Among them, success can be understood as meeting the requirements of the management and control strategy a. Failure can be understood as not meeting the requirements of control strategy a.

在满足管控策略a的要求的情况下，第一视频流媒体服务平台执行S303。反之，在不满足管控策略a的要求的情况下，第一视频流媒体服务平台执行S304。其中，S303和S304的说明如下：Under the condition that the requirements of the management and control policy a are satisfied, the first video streaming media service platform executes S303. On the contrary, in the case that the requirements of the management and control policy a are not met, the first video streaming media service platform executes S304. Among them, the descriptions of S303 and S304 are as follows:

S303、第一视频流媒体服务平台为第一客户端设备意图获取的目标业务流取流。S303. The first video streaming media service platform obtains a stream for the target service stream that the first client device intends to obtain.

也就是说，第一视频流媒体服务平台响应于取流请求，根据管控策略执行针对目标监控点的取流行为，以获取上述目标业务流，并向第一客户端设备发送上述目标业务流。相应的，第一客户端设备接收来自第一视频流媒体服务平台的目标业务流。That is, the first video streaming service platform, in response to the stream fetch request, executes the stream fetch behavior for the target monitoring point according to the management and control policy, so as to obtain the above-mentioned target service flow, and sends the above-mentioned target service flow to the first client device. Correspondingly, the first client device receives the target service stream from the first video streaming service platform.

例如，以图2中的曲线a所示为例，第一客户端设备意图获取的目标业务流来自本域前端设备集群102，也就是说，关联对象a至少包括第一客户端设备、第一视频流媒体服务平台和本域前端设备集群102中的两项或多项。此种情况下，第一视频流媒体服务平台从本域前端设备集群102取流，将获取的目标业务流反馈给第一客户端设备，以使第一客户端设备播放该目标业务流。For example, taking the curve a in FIG. 2 as an example, the target service flow that the first client device intends to acquire comes from the local front-end device cluster 102, that is, the associated object a includes at least the first client device, the first Two or more of the video streaming service platform and the local front-end equipment cluster 102 . In this case, the first video streaming service platform obtains the stream from the local front-end device cluster 102, and feeds back the obtained target service stream to the first client device, so that the first client device plays the target service stream.

再如，以图2中的曲线c所示为例，第一客户端设备意图获取的目标业务流来自第二邻域前端设备集群122。也就是说，关联对象a至少包括第一客户端设备、第一视频流媒体服务平台和第二邻域前端设备集群122中的两项或多项。此种情况下，如图4a所示，第一视频流媒体服务平台执行如下步骤：For another example, taking the curve c in FIG. 2 as an example, the target service flow that the first client device intends to acquire comes from thecluster 122 of front-end devices in the second neighborhood. That is to say, the associated object a includes at least two or more items of the first client device, the first video streaming media service platform, and the second neighborhood front-end device cluster 122 . In this case, as shown in Figure 4a, the first video streaming service platform performs the following steps:

步骤1a，第一视频流媒体服务平台向第二视频流媒体服务平台发送第二取流请求。相应的，第二视频流媒体服务平台接收来自第一视频流媒体服务平台的第二取流请求。Step 1a, the first video streaming media service platform sends a second streaming request to the second video streaming media service platform. Correspondingly, the second video streaming media service platform receives the second streaming request from the first video streaming media service platform.

其中，第二视频流媒体服务平台是第一视频流媒体服务平台的下级平台。以图2中曲线c所示为例，第二视频流媒体服务平台是第二邻域视频流媒体服务平台120。Wherein, the second video streaming media service platform is a subordinate platform of the first video streaming media service platform. Taking the curve c in FIG. 2 as an example, the second video streaming media service platform is the second neighborhood video streamingmedia service platform 120 .

其中，第二取流请求用于请求获取目标监控点的目标业务流。第二取流请求指示的目标业务流与多个关联对象b相关联。关联对象b至少包括第一视频流媒体服务平台、第二视频流媒体服务平台和第二邻域前端设备集群122中的两项或多项。目标监控点可以参见第一取流请求的介绍，此处不再赘述。示例性的，第二取流请求指示第一视频流媒体服务平台意图获取目标监控点的n1路视频流。Wherein, the second flow fetching request is used to request to obtain the target service flow of the target monitoring point. The target service flow indicated by the second flow fetching request is associated with multiple association objects b. The association object b includes at least two or more items of the first video streaming media service platform, the second video streaming media service platform, and the second neighborhood front-end device cluster 122 . For the target monitoring point, reference may be made to the introduction of the first stream fetching request, which will not be repeated here. Exemplarily, the second stream acquisition request indicates that the first video streaming media service platform intends to acquire n1 video streams of the target monitoring point.

步骤2a、第二视频流媒体服务平台根据管控策略b对第二取流请求进行校验，以得到第二取流请求的校验结果。In step 2a, the second video streaming media service platform verifies the second stream fetching request according to the management and control policy b, so as to obtain a verification result of the second stream fetching request.

其中，管控策略b用于组合管控关联对象b中每个关联对象针对目标监控点的取流行为。针对管控策略b，组合管控的关联对象可以记为目标关联对象2。目标关联对象2可以包括第一视频流媒体服务平台和第二视频流媒体服务平台，或包括第一视频流媒体服务平台和第二邻域前端设备集群122，或包括第一视频流媒体服务平台、第二视频流媒体服务平台和第二邻域前端设备集群122，或其他组合方式，本申请实施例对此不作限定。相比于管控策略a而言，区别点在于，管控策略b是关于目标关联对象2的管控策略，其他可以参见管控策略a的介绍，此处不再赘述。Among them, the management and control strategy b is used to combine the management and control of the acquisition behavior of each associated object in the associated object b with respect to the target monitoring point. For the management and control strategy b, the associated object of combined management and control can be recorded as the target associated object 2 . The target associated object 2 may include the first video streaming media service platform and the second video streaming media service platform, or include the first video streaming media service platform and the second neighborhood front-end equipment cluster 122, or include the first video streaming media service platform , the second video streaming media service platform and the second neighborhood front-end device cluster 122 , or other combinations, which are not limited in this embodiment of the present application. Compared with the management and control strategy a, the difference is that the management and control strategy b is a management and control strategy for the target associated object 2. For others, please refer to the introduction of the management and control strategy a, which will not be repeated here.

其中，步骤2a的实现过程可以参见S302中示例1至示例3的介绍，此处不再赘述。For the implementation process of step 2a, reference may be made to the introduction of Example 1 to Example 3 in S302, which will not be repeated here.

在满足管控策略b的要求的情况下，第二视频流媒体服务平台为第一视频流媒体服务平台意图获取的目标业务流取流，如第二视频流媒体服务平台从第二邻域前端设备集群122取流，将获取的目标业务流反馈给第一视频流媒体服务平台，以使第一视频流媒体服务平台反馈给第一客户端设备，从而使得第一客户端设备播放该目标业务流。反之，在不满足管控策略b的要求的情况下，第二视频流媒体服务平台拒绝为第一视频流媒体服务平台意图获取的目标业务流取流。Under the condition that the requirements of the management and control policy b are met, the second video streaming service platform obtains the stream for the target service stream that the first video streaming service platform intends to obtain. Thecluster 122 fetches the stream, and feeds back the acquired target service stream to the first video streaming service platform, so that the first video streaming service platform feeds back to the first client device, so that the first client device plays the target service stream . On the contrary, in the case that the requirements of the management and control policy b are not met, the second video streaming media service platform refuses to obtain the stream for the target service stream that the first video streaming media service platform intends to obtain.

应理解，此处仅以第一视频流媒体服务平台是本域视频流媒体服务平台100，且第一客户端设备意图获取的目标业务流来自第二邻域前端设备集群122为例，进行介绍。而在图2的曲线e所示中，第一视频流媒体服务平台是第一邻域视频流媒体服务平台110，第一客户端设备是第一邻域客户端设备113，且第一客户端设备意图获取的目标业务流来自第二邻域前端设备集群122的情况下，在上述步骤1a和步骤2a中，第一视频流媒体服务平台实现为第一邻域视频流媒体服务平台110，第二视频流媒体服务平台实现为本域视频流媒体服务平台100。由于第二邻域前端设备集群122接入的视频流媒体服务平台是第二邻域视频流媒体服务平台120，所以，本域视频流媒体服务平台100再向第二邻域视频流媒体服务平台120发送第三取流请求。相应的，第二邻域视频流媒体服务平台120接收来自本域视频流媒体服务平台100的第三取流请求。其中，第三取流请求用于请求获取目标监控点的目标业务流。第三取流请求指示的目标业务流与多个关联对象c相关联。关联对象c至少包括第一客户端设备、本域视频流媒体服务平台100和第二邻域前端设备集群122中的两项或多项。第二邻域视频流媒体服务平台120根据管控策略c对第三取流请求进行校验，以得到第三取流请求的校验结果。其中，管控策略c用于组合管控目标关联对象3中每个关联对象针对目标监控点的取流行为。针对管控策略c，组合管控的关联对象可以记为目标关联对象3。相比于管控策略a而言，区别点在于，管控策略c是关于目标关联对象3的管控策略，其他可以参见管控策略a的介绍，此处不再赘述。示例性的，管控策略c指示目标关联对象3针对目标监控点允许的取流路数。第二邻域视频流媒体服务平台120根据第三检验结果确定是否为本域视频流媒体服务平台100意图获取的目标业务流取流，具体可以参见上述步骤2a的介绍，此处不再赘述。It should be understood that the introduction is made by taking the first video streaming service platform being the local videostreaming service platform 100 and the target service flow that the first client device intends to acquire from the second neighborhood front-end device cluster 122 as an example. . As shown in the curve e of FIG. 2 , the first video streaming service platform is the first neighborhood videostreaming service platform 110 , the first client device is the firstneighborhood client device 113 , and the first client When the target service flow that the device intends to acquire comes from the second neighborhood front-end device cluster 122, in the above steps 1a and 2a, the first video streaming media service platform is implemented as the first neighborhood video streamingmedia service platform 110, and the first video streaming media service platform The second video streaming media service platform is implemented as the local video streamingmedia service platform 100 . Since the video streaming media service platform accessed by the second neighborhood front-end device cluster 122 is the second neighborhood video streamingmedia service platform 120, the local video streamingmedia service platform 100 then sends the second neighborhood video streaming media service platform to the second neighborhood video streamingmedia service platform 120. 120 Send a third streaming request. Correspondingly, the second neighborhood video streamingmedia service platform 120 receives the third streaming request from the local domain video streamingmedia service platform 100 . Wherein, the third flow fetching request is used to request to obtain the target service flow of the target monitoring point. The target service flow indicated by the third flow retrieval request is associated with multiple association objects c. The associated object c at least includes two or more items of the first client device, the videostreaming service platform 100 in the local area, and the second neighborhood front-end device cluster 122 . The second-neighborhood video streamingmedia service platform 120 verifies the third streaming request according to the management and control policy c, so as to obtain a verification result of the third streaming request. Among them, the management and control strategy c is used to combine and control the fetching behavior of each associated object in the target associated object 3 with respect to the target monitoring point. For the management and control strategy c, the associated object of combined management and control can be recorded as the target associated object 3 . Compared with the management and control strategy a, the difference is that the management and control strategy c is a management and control strategy for the target associated object 3. For others, please refer to the introduction of the management and control strategy a, which will not be repeated here. Exemplarily, the management and control policy c indicates the number of access paths allowed by the target associated object 3 for the target monitoring point. The second neighborhood videostreaming service platform 120 determines whether the target service stream intended to be acquired by the local videostreaming service platform 100 is fetched according to the third test result. For details, please refer to the introduction of the above step 2a, which will not be repeated here.

又如，以图2中曲线d所示为例，第一客户端设备意图获取的目标业务流来自第三邻域前端设备集群132。也就是说，关联对象a至少包括第一客户端设备、第一视频流媒体服务平台和第三邻域前端设备集群132中的两项或多项。此种情况下，如图4b所示，第一视频流媒体服务平台执行如下步骤：For another example, taking the curve d in FIG. 2 as an example, the target service flow that the first client device intends to acquire comes from thecluster 132 of front-end devices in the third neighborhood. That is to say, the associated object a includes at least two or more items of the first client device, the first video streaming media service platform, and the third neighborhood front-end device cluster 132 . In this case, as shown in Figure 4b, the first video streaming service platform performs the following steps:

步骤1b，第一视频流媒体服务平台向边缘网关130发送第二取流请求。相应的，边缘网关130接收来自第一视频流媒体服务平台的第二取流请求。Step 1b, the first video streaming media service platform sends a second streaming request to theedge gateway 130. Correspondingly, theedge gateway 130 receives the second streaming request from the first video streaming media service platform.

其中，边缘网关130与第一视频流媒体服务平台通信连接，也属于第一视频流媒体服务平台的下级平台。Theedge gateway 130 is in communication connection with the first video streaming media service platform, and also belongs to the subordinate platform of the first video streaming media service platform.

其中，第二取流请求可以参见步骤1a的介绍。相比于步骤1a，步骤1b中的关联对象b至少包括第一视频流媒体服务平台、第二视频流媒体服务平台和第三邻域前端设备集群132。For the second stream fetching request, please refer to the introduction of step 1a. Compared with step 1a, the associated object b in step 1b includes at least the first video streaming media service platform, the second video streaming media service platform, and the third neighborhood front-end device cluster 132 .

步骤2b，边缘网关130根据管控策略b对第二取流请求进行校验，以得到第二取流请求的校验结果。Step 2b, theedge gateway 130 verifies the second flow fetching request according to the management and control policy b, so as to obtain a verification result of the second flow fetching request.

其中，步骤2b可以参见步骤2a的介绍，此处不再赘述。Wherein, for step 2b, reference may be made to the introduction of step 2a, and details are not repeated here.

在满足管控策略b的要求的情况下，边缘网关130为第一视频流媒体服务平台意图获取的目标业务流取流，如边缘网关130从第三邻域前端设备集群132取流，将获取的目标业务流反馈给第一视频流媒体服务平台，以使第一视频流媒体服务平台反馈给第一客户端设备，从而使得第一客户端设备播放该目标业务流。反之，在不满足管控策略b的要求的情况下，边缘网关130拒绝为第一视频流媒体服务平台意图获取的目标业务流取流。Under the condition that the requirements of the management and control policy b are met, theedge gateway 130 obtains the stream for the target service stream that the first video streaming media service platform intends to obtain. The target service stream is fed back to the first video streaming media service platform, so that the first video streaming media service platform is fed back to the first client device, so that the first client device can play the target service stream. On the contrary, in the case that the requirements of the management and control policy b are not satisfied, theedge gateway 130 refuses to obtain the stream for the target service stream that the first video streaming media service platform intends to obtain.

应理解，此处仅以第一视频流媒体服务平台是本域视频流媒体服务平台100，且第一客户端设备意图获取的目标业务流来自第三邻域前端设备集群132为例，进行介绍。而在图2的曲线f所示例子中，第一视频流媒体服务平台是第一邻域视频流媒体服务平台110，第一客户端设备是第一邻域客户端设备113，且第一客户端设备意图获取的目标业务流来自第三邻域前端设备集群132的情况下，在上述步骤1a和步骤2a中，第一视频流媒体服务平台实现为第一邻域视频流媒体服务平台110，第二视频流媒体服务平台实现为本域视频流媒体服务平台100。由于第三邻域前端设备集群132接入的是边缘网关130，所以，本域视频流媒体服务平台100再向边缘网关130发送第三取流请求。相应的，边缘网关130接收来自本域视频流媒体服务平台100的第三取流请求。其中，第三取流请求用于请求获取目标监控点的目标业务流。第三取流请求指示的目标业务流与多个关联对象c相关联。关联对象c至少包括本域视频流媒体服务平台100、边缘网关130和第三邻域前端设备集群132中的两项或多项。边缘网关130根据管控策略c对第三取流请求进行校验，以得到第三取流请求的校验结果。边缘网关130根据第三取流请求的校验结果确定是否为本域视频流媒体服务平台100意图获取的目标业务流取流，具体可以参见上述步骤2a的介绍，此处不再赘述。It should be understood that, here, only the first video streaming service platform is the local videostreaming service platform 100, and the target service flow that the first client device intends to acquire comes from the third neighborhood front-end device cluster 132 as an example, for introduction . In the example shown by the curve f in FIG. 2, the first video streaming service platform is the first neighborhood videostreaming service platform 110, the first client device is the firstneighborhood client device 113, and the first client When the target service flow that the terminal device intends to acquire comes from the third neighborhood front-end device cluster 132, in the above steps 1a and 2a, the first video streaming media service platform is implemented as the first neighborhood video streamingmedia service platform 110, The second video streaming media service platform is implemented as a local video streamingmedia service platform 100 . Since the front-end device cluster 132 in the third neighborhood is connected to theedge gateway 130 , the local video streamingmedia service platform 100 sends a third streaming request to theedge gateway 130 . Correspondingly, theedge gateway 130 receives the third streaming request from the videostreaming service platform 100 of the local domain. Wherein, the third flow fetching request is used to request to obtain the target service flow of the target monitoring point. The target service flow indicated by the third flow retrieval request is associated with multiple association objects c. The associated object c at least includes two or more items from the videostreaming service platform 100 in the local area, theedge gateway 130 and the front-end device cluster 132 in the third neighborhood. Theedge gateway 130 verifies the third stream fetching request according to the management and control policy c, to obtain a verification result of the third stream fetching request. Theedge gateway 130 determines, according to the verification result of the third streaming request, whether the target service stream intended to be acquired by the local videostreaming service platform 100 is to be acquired.

示例性的，如图3b所示，第一视频流媒体服务平台通过媒体组件向第一客户端设备返回目标业务流。Exemplarily, as shown in FIG. 3b, the first video streaming media service platform returns the target service stream to the first client device through the media component.

S304、第一视频流媒体服务平台拒绝为第一客户端设备意图获取的目标业务流取流。S304. The first video streaming media service platform refuses to obtain a stream for the target service stream that the first client device intends to obtain.

示例性的，如图3b所示，第一视频流媒体服务平台的媒体组件向第一客户端设备返回错误码。仍以图2中曲线a所示为例，第一客户端设备意图获取的目标业务流来自本域前端设备集群102，第一视频流媒体服务平台拒绝从本域前端设备集群102取流。此种情况下，第一视频流媒体服务平台无法向第一客户端设备提供目标业务流，第一客户端设备不播放该目标业务流。Exemplarily, as shown in FIG. 3b, the media component of the first video streaming media service platform returns an error code to the first client device. Still taking the curve a in FIG. 2 as an example, the target service flow that the first client device intends to acquire comes from the local front-end device cluster 102 , and the first video streaming service platform refuses to obtain the stream from the local front-end device cluster 102 . In this case, the first video streaming media service platform cannot provide the target service stream to the first client device, and the first client device does not play the target service stream.

在一些实施例中，本申请实施例取流控制方法还能够执行剔除操作，如图3c所示。若用户甲和用户乙意图获取的目标业务流均来自同一前端设备，或经由同一服务平台。其中，用户甲的取流路数为x，用户乙的取流路数为y，第一视频流媒体服务平台的VNSC组件允许的取流路数为z，且x+y＞z。以图2中曲线a所示的场景为例，用户甲和用户乙意图获取的目标业务流均来自同一前端设备，如本域前端设备集群102。用户甲和用户乙意图获取的目标业务流经由同一服务平台，如本域视频流媒体服务平台100。在用户乙正常取流的过程中，用户甲发起了取流请求。所以，第一视频流媒体服务平台的VNSC组件确定取流达到了设定的阈值上限z，所以，第一视频流媒体服务平台的VNSC组件筛选出权限值最低的会话ID。其中，维度可以理解为，前端设备，且该前端设备是指，提供用户甲和用户乙意图获取的目标业务流的前端设备，如本域前端设备集群102。维度也可以理解为，服务平台，且该服务平台是指，用户甲和用户乙意图获取的目标业务流经由的服务平台，如本域视频流媒体服务平台100。权限值表征关联对象的重要程度，如权限值越高，则该关联对象的重要程度越高。反之，权限值越低，则该关联对象的重要程度越低。例如，以本域前端设备集群102这一维度为例，VNSC组件确定由本域前端设备集群102提供目标业务流的多个用户中每个用户的权限值，选出权限值最低的用户所对应的会话ID。然后，VNSC组件向媒体组件发送剔除消息。其中，剔除消息中携带有上述会话ID，以指示媒体组件剔除该会话ID标识的链路，实现断流。In some embodiments, the flow control method according to the embodiment of the present application can also perform a culling operation, as shown in FIG. 3c . If the target business flows that User A and User B intend to obtain come from the same front-end device or through the same service platform. The number of access paths for user A is x, the number of access paths for user B is y, the number of access paths allowed by the VNSC component of the first video streaming service platform is z, and x+y>z. Taking the scenario shown by the curve a in FIG. 2 as an example, the target service flows that user A and user B intend to acquire both come from the same front-end device, such as the front-end device cluster 102 in the domain. The target service flows that User A and User B intend to acquire pass through the same service platform, such as the local video streamingmedia service platform 100 . During the process of user B's normal stream access, user A initiates a stream access request. Therefore, the VNSC component of the first video streaming media service platform determines that the stream access has reached the set upper threshold z, and therefore, the VNSC component of the first video streaming media service platform filters out the session ID with the lowest permission value. The dimension can be understood as the front-end device, and the front-end device refers to the front-end device that provides the target service flow that User A and User B intend to acquire, such as the front-end device cluster 102 in the domain. The dimension can also be understood as a service platform, and the service platform refers to the service platform through which the target business flow that User A and User B intend to acquire, such as the local video streamingmedia service platform 100 . The authority value represents the importance of the associated object. For example, the higher the authority value, the higher the importance of the associated object. Conversely, the lower the authority value, the lower the importance of the associated object. For example, taking the dimension of the front-end device cluster 102 of the local domain as an example, the VNSC component determines the permission value of each user among the multiple users whose target service flow is provided by the front-end device cluster 102 of the local domain, and selects the user with the lowest permission value. Session ID. Then, the VNSC component sends a culling message to the media component. Wherein, the delete message carries the above session ID to instruct the media component to delete the link identified by the session ID, so as to cut off the flow.

在一些实施例中，如图5a所示，第一视频流媒体服务平台执行S302之前，执行S305：In some embodiments, as shown in FIG. 5a, before the first video streaming media service platform performs S302, it performs S305:

S305、第一视频流媒体服务平台确定第一场景。S305. The first video streaming media service platform determines the first scene.

其中，第一场景与第一取流请求对应。The first scenario corresponds to the first streaming request.

例如，以时间维度为例，第一场景是基于时间信息确定的。具体地，第一视频流媒体服务平台根据时刻a来确定第一场景，如时刻a是否在预设时间段内来确定第一场景。其中，时刻a作为时间信息，时刻a可以是执行S301之后的一个时刻，如执行S305的时刻，也可以是第一取流请求的接收时刻，还可以是第一取流请求指示的时刻，如指示目标业务流的播放时刻，本申请实施例对时刻a的具体实现不作限定。预设时间段可以是节假日，如10月1日00:00至10月8日00:00，或1月1日00:00至1月2日00:00。若时刻a在预设时间段内，则第一场景为假期场景，如国庆假期，元旦假期等。For example, taking the time dimension as an example, the first scene is determined based on time information. Specifically, the first video streaming service platform determines the first scene according to the time a, such as whether the time a is within a preset time period to determine the first scene. Wherein, the time a is used as time information, and the time a may be a time after the execution of S301, such as the time of executing S305, the time of receiving the first stream request, or the time indicated by the first stream request, such as Indicates the playing time of the target service stream, and the specific implementation of time a is not limited in this embodiment of the present application. The preset time period can be a holiday, such as 00:00 on October 1st to 00:00 on October 8th, or 00:00 on January 1st to 00:00 on January 2nd. If the time a is within the preset time period, the first scene is a holiday scene, such as a National Day holiday, a New Year's Day holiday, and the like.

再如，以地理位置维度为例，第一场景是基于位置信息确定的。具体地，第一视频流媒体服务平台根据位置信息来确定第一场景，如位置信息指示的位置是否在预设位置区域内来确定第一场景。其中，位置信息可以是第一客户端设备所在位置的信息，也可以是其他位置的信息，如第一客户端设备所在位置附近的某一位置的信息。预设位置区域可以包括某一城市中图书馆的位置区域，或动物园的位置区域等。若位置信息指示的位置在图书馆的位置区域内，则第一场景为图书馆场景。若位置信息指示的位置在动物园的位置区域内，则第一场景为动物园场景。For another example, taking the geographic location dimension as an example, the first scenario is determined based on location information. Specifically, the first video streaming service platform determines the first scene according to the location information, such as whether the location indicated by the location information is within a preset location area to determine the first scene. The location information may be information about the location where the first client device is located, or may be information about other locations, such as information about a location near the location where the first client device is located. The preset location area may include the location area of a library in a certain city, or the location area of a zoo, and the like. If the location indicated by the location information is within the location area of the library, the first scene is a library scene. If the location indicated by the location information is within the location area of the zoo, the first scene is the zoo scene.

应理解，以上仅以国庆假期场景、元旦假期场景、图书馆场景、动物园场景为例进行介绍，第一场景还可以有其他示例，本申请实施例不再一一赘述。It should be understood that the above only takes a National Day holiday scenario, a New Year's Day holiday scenario, a library scenario, and a zoo scenario as examples for introduction, and the first scenario may also have other examples, which will not be repeated in this embodiment of the present application.

相应的，在第一视频流媒体服务平台执行S305的情况下，S302替换为S302a：Correspondingly, when the first video streaming media service platform executes S305, S302 is replaced with S302a:

S302a、第一视频流媒体服务平台根据第一管控策略对第一取流请求进行校验，以得到第一取流请求的校验结果a。S302a, the first video streaming media service platform verifies the first streaming request according to the first management and control policy, so as to obtain a verification result a of the first streaming request.

其中，第一视频流媒体服务平台根据第一场景确定目标管控策略，此处将目标管控策略也称为第一管控策略。第一管控策略是管控策略a中与第一场景对应的管控策略。第一管控策略用于在第一场景下，管控目标关联对象1中每个关联对象针对目标监控点的取流行为。例如，以第一场景是假期场景为例，第一管控策略指示在国庆假期场景下，用户甲针对回放允许的取流路数为N2，以及第一视频流媒体服务平台针对回放允许的取流路数为N2’。再如，以第一场景是图书馆场景为例，第一管控策略指示在图书馆场景下，用户甲针对回放允许的取流路数为N3，以及第一视频流媒体服务平台针对回放允许的取流路数为N3’。又如，以第一场景是动物园场景为例，第一管控策略指示在图书馆场景下，用户甲针对回放允许的取流路数为N4，以及第一视频流媒体服务平台针对回放允许的取流路数为N4’。The first video streaming service platform determines a target management and control strategy according to the first scenario, and the target management and control strategy is also referred to as a first management and control strategy herein. The first management and control strategy is a management and control strategy corresponding to the first scenario in the management and control strategy a. The first management and control strategy is used to manage and control the fetching behavior of each associated object in the target associated object 1 with respect to the target monitoring point in the first scenario. For example, taking the first scenario as a holiday scenario as an example, the first control policy indicates that in the National Day holiday scenario, the number of streams allowed by User A for playback is N2, and the number of streams allowed by the first video streaming service platform for playback is N2 The number of paths is N2'. For another example, taking the first scene as a library scene as an example, the first control policy indicates that in the library scene, the number of streams allowed by User A for playback is N3, and the number of streams allowed by the first video streaming service platform for playback is N3. Take the number of flow paths as N3'. As another example, taking the first scene as the zoo scene as an example, the first management and control policy indicates that in the library scene, the number of streams allowed by User A for playback is N4, and the number of streams allowed by the first video streaming service platform for playback is N4. The number of flow paths is N4'.

示例性的，第一管控策略的实现形式如表2所示：Exemplarily, the implementation form of the first management and control strategy is shown in Table 2:

表2Table 2

在表2中，一个预案可以对应一项管控策略。每两个预案中的管控策略，可以完全不同，也可以部分相同，本申请实施例对此不作限定。国庆节预案，可以理解为国庆节场景下实施的预案。日常预案，可以理解为除国庆节之外的普通日常场景下实施的预案。以目标业务流回放为例，表2给出了日常预案和国庆节预案。其中，国庆预案的执行时间是2021年10月1日的00:00至2021年10月7日的23:59，最大允许的取流路数为N2，目标业务流的内容可以是与欢度国庆相关的视频流。日常预案的执行时间是2021年10月8日的00:00至2022年9月30日的23:59，最大允许的取流路数为X，目标业务流的内容可以是与广告相关的视频流。示例性的，在第一场景为国庆节场景的情况下，第一管控策略可以实现为表2中的国庆节预案。In Table 2, a plan can correspond to a control strategy. The management and control strategies in each of the two plans may be completely different, or may be partially the same, which is not limited in this embodiment of the present application. The National Day plan can be understood as the plan implemented under the National Day scene. Daily plans can be understood as plans implemented in ordinary daily scenarios except for National Day. Taking the target service stream playback as an example, Table 2 shows the daily plan and the National Day plan. Among them, the implementation time of the National Day plan is from 00:00 on October 1, 2021 to 23:59 on October 7, 2021, the maximum allowed number of access channels is N2, and the content of the target business stream can be related to celebrating the National Day. related video streams. The execution time of the daily plan is from 00:00 on October 8, 2021 to 23:59 on September 30, 2022. The maximum allowed number of streams is X, and the content of the target business stream can be videos related to advertisements. flow. Exemplarily, when the first scenario is a National Day scenario, the first management and control strategy may be implemented as the National Day holiday plan in Table 2.

其中，S302a的具体实现包括如下示例：The specific implementation of S302a includes the following examples:

示例1a，以假期场景为例，针对用户甲，第一取流请求指示用户甲获取n1路预览视频流。此种情况下，第一视频流媒体服务平台采用的第一管控策略至少指示：在假期场景下，用户甲针对目标监控点的预览业务允许的最大取流路数为N2。在原有已请求路数n0的基础上，再新增请求n1路预览视频流后，若n0+n1之和小于或等于N2，则第一取流请求的校验结果a指示满足第一管控策略的要求。反之，若n0+n1之和大于N2，则第一取流请求的校验结果a指示不满足第一管控策略的要求。Example 1a, taking a holiday scenario as an example, for user A, the first stream request instructs user A to obtain n1 preview video streams. In this case, the first management and control strategy adopted by the first video streaming service platform at least indicates that in the holiday scenario, the maximum number of access streams allowed by User A for the preview service of the target monitoring point is N2. On the basis of the original number of requested channels n0, after adding n1 channels of preview video streams, if the sum of n0+n1 is less than or equal to N2, the verification result a of the first streaming request indicates that the first control policy is satisfied requirements. Conversely, if the sum of n0+n1 is greater than N2, the verification result a of the first flow fetch request indicates that the requirements of the first management and control policy are not met.

示例2a，以图书馆场景为例，针对用户甲，第一取流请求指示用户甲获取n1路预览视频流。此种情况下，第一视频流媒体服务平台采用的第一管控策略至少指示：在图书馆场景下，用户甲针对目标监控点的预览业务允许的最大取流路数为N3。在原有已请求路数n0的基础上，再新增请求n1路预览视频流后，若n0+n1之和小于或等于N3，则第一取流请求的校验结果a指示满足第一管控策略的要求。反之，若n0+n1之和大于N3，则第一取流请求的校验结果a指示不满足第一管控策略的要求。Example 2a, taking the library scene as an example, for user A, the first stream request instructs user A to obtain n1 preview video streams. In this case, the first management and control strategy adopted by the first video streaming media service platform at least indicates: in the library scenario, the maximum number of access streams allowed by User A for the preview service of the target monitoring point is N3. On the basis of the original number of requested channels n0, after adding a new request for n1 channels of preview video streams, if the sum of n0+n1 is less than or equal to N3, the verification result a of the first streaming request indicates that the first control policy is satisfied requirements. Conversely, if the sum of n0+n1 is greater than N3, the verification result a of the first flow fetching request indicates that the requirements of the first management and control policy are not met.

示例3a，以动物园场景为例，针对用户甲，第一取流请求指示用户甲获取n1路预览视频流。此种情况下，第一视频流媒体服务平台采用的第一管控策略至少指示：在动物园场景下，用户甲针对目标监控点的预览业务允许的最大取流路数为N4。在原有已请求路数n0的基础上，再新增请求n1路预览视频流后，若n0+n1之和小于或等于N4，则第一取流请求的校验结果a指示满足第一管控策略的要求。反之，若n0+n1之和大于N4，则第一取流请求的校验结果a指示不满足第一管控策略的要求。Example 3a, taking the zoo scene as an example, for user A, the first streaming request instructs user A to obtain n1 preview video streams. In this case, the first management and control strategy adopted by the first video streaming service platform at least indicates that in the zoo scenario, the maximum number of streams allowed by User A for the preview service of the target monitoring point is N4. On the basis of the original number of requested channels n0, after adding a new request for n1 channels of preview video streams, if the sum of n0+n1 is less than or equal to N4, the verification result a of the first stream request indicates that the first control policy is satisfied requirements. Conversely, if the sum of n0+n1 is greater than N4, the verification result a of the first flow fetch request indicates that the requirements of the first management and control policy are not met.

应理解，上述示例1a到示例3a中，n0为正整数。上述示例1a到示例3a仅示出了单个关联对象的处理过程。而第一管控策略用于组合管控关联对象a中每个关联对象的取流行为，所以，S302a包括上述示例的组合，或其他示例的组合，可以参见S302的介绍，此处不再一一赘述。It should be understood that in the above examples 1a to 3a, n0 is a positive integer. The above examples 1a to 3a only show the processing of a single associated object. The first management and control strategy is used to combine and control the retrieval behavior of each associated object in the associated object a. Therefore, S302a includes a combination of the above examples, or a combination of other examples, you can refer to the introduction of S302, which will not be repeated here. .

相应的，在第一视频流媒体服务平台执行S302a的情况下，S303中的目标业务流是满足第一管控策略的视频流。若第一场景是国庆假期场景，则第一客户端设备上播放关于欢度国庆的视频流。若第一场景是元旦假期场景，则第一客户端设备上播放关于欢度元旦的视频流。若第一场景是图书馆场景，则第一客户端设备上播放关于图书介绍的视频流。若第一场景是动物园场景，则第一客户端设备上播放关于动物介绍的视频流。Correspondingly, when the first video streaming media service platform executes S302a, the target service stream in S303 is a video stream that satisfies the first management and control policy. If the first scene is a National Day holiday scene, a video stream about celebrating the National Day is played on the first client device. If the first scene is a New Year's Day holiday scene, the first client device plays a video stream about celebrating New Year's Day. If the first scene is a library scene, the video stream about the book introduction is played on the first client device. If the first scene is a zoo scene, a video stream about the introduction of the animal is played on the first client device.

如此，在不同的场景下，第一视频视频流媒体服务平台能够灵活、快捷地确定与第一场景匹配的管控策略，即上述第一管控策略，以对第一取流请求进行校验，从而向第一客户端设备提供满足相应管控策略的目标业务流，使得第一客户端设备上播放与第一场景相匹配的目标业务流，满足不同场景下的视频切换播放的需求。In this way, in different scenarios, the first video streaming media service platform can flexibly and quickly determine a management and control strategy that matches the first scenario, that is, the above-mentioned first management and control strategy, so as to verify the first streaming request, thereby The first client device is provided with a target service stream that satisfies the corresponding management and control policy, so that the first client device plays the target service stream matching the first scene to meet the needs of video switching and playback in different scenarios.

应理解，S302a中仅以管控策略a中与场景匹配的第一管控策略为例，进行介绍。类似的，管控策略b中也存在与场景匹配的条件，和/或，管控策略c中也存在与场景匹配的条件，具体校验过程可以参见S302a的描述，此处不再一一赘述。It should be understood that, in S302a, only the first management and control strategy matching the scenario in the management and control strategy a is used as an example for introduction. Similarly, the management and control strategy b also has conditions that match the scenario, and/or the management and control strategy c also has conditions that match the scenario. For the specific verification process, please refer to the description of S302a, which will not be repeated here.

在一些实施例中，部分关联对象与监控点的业务权限绑定，以基于监控点的业务权限来管控取流行为，具体步骤如图5b所示，S302替换为S302b：In some embodiments, some associated objects are bound with the business authority of the monitoring point, so as to manage and control the access behavior based on the business authority of the monitoring point. The specific steps are shown in Figure 5b, and S302 is replaced by S302b:

S302b、第一视频流媒体服务平台根据第二管控策略对第一取流请求进行校验，以得到第一取流请求的校验结果b。S302b, the first video streaming media service platform verifies the first streaming request according to the second management and control policy, so as to obtain a verification result b of the first streaming request.

其中，管控策略a包括第二管控策略。第二管控策略指示基于目标监控点的业务权限配置，组合管控关联对象a中每个关联对象针对目标监控点的取流行为。目标监控点的业务权限可以被配置为开启或关闭。Wherein, the management and control strategy a includes a second management and control strategy. The second management and control policy indicates that based on the business authority configuration of the target monitoring point, the combined control and control of the access behavior of each associated object in the associated object a with respect to the target monitoring point. The business permission of the target monitoring point can be configured to be enabled or disabled.

示例性的，预配置的监控点有多个。以N个监控点为例，分别记为监控点1至N。N为正整数。每个监控点上部署有云台，云台上安置有图像采集设备。取流控制系统可以预先配置每个监控点的业务权限。其中，监控点的业务权限，可以理解为，监控点上的图像采集设备所采集的视频流针对上述目标业务的权限。监控点的业务权限开启，可以理解为，监控点上的图像采集设备所采集的视频流允许预览、回放或下载。监控点的业务权限关闭，可以理解为，监控点上的图像采集设备所采集的视频流不允许预览、回放和下载。Exemplarily, there are multiple preconfigured monitoring points. Taking N monitoring points as an example, they are recorded as monitoring points 1 to N respectively. N is a positive integer. A PTZ is deployed on each monitoring point, and an image acquisition device is installed on the PTZ. The flow control system can pre-configure the business authority of each monitoring point. The service authority of the monitoring point can be understood as the authority of the video stream collected by the image acquisition device on the monitoring point for the above-mentioned target service. When the service authority of the monitoring point is enabled, it can be understood that the video stream collected by the image acquisition device on the monitoring point is allowed to be previewed, played back or downloaded. When the service authority of the monitoring point is closed, it can be understood that the video stream collected by the image acquisition device on the monitoring point is not allowed to preview, play back and download.

其中，目标监控点可以是上述监控点1，目标监控点上的图像采集设备可以是上述本域前端设备集群102，以采集第一客户端设备意图获取的目标业务流。示例性的，目标监控点的业务权限配置方式如下：仍以N个监控点为例，针对某一目标关联对象1而言，若该目标关联对象1针对目标业务的业务权限是开启，且上述N个监控点全部未被选中，则默认上述N个监控点针对该目标业务的业务权限均开启。若该目标关联对象1针对目标业务的业务权限是开启，且上述N个监控点中监控点1未被选中，监控点2至监控点N被选中，则默认上述监控点1针对目标业务的业务权限开启。The target monitoring point may be the above-mentioned monitoring point 1, and the image acquisition device on the target monitoring point may be the above-mentioned local front-end device cluster 102 to collect the target service flow that the first client device intends to acquire. Exemplarily, the configuration method of the business authority of the target monitoring point is as follows: still taking N monitoring points as an example, for a certain target associated object 1, if the target associated object 1's business authority for the target service is enabled, and the above If none of the N monitoring points are selected, by default, the service permissions of the above N monitoring points for the target service are all enabled. If the service authority of the target associated object 1 for the target service is enabled, and the monitoring point 1 is not selected among the above N monitoring points, and the monitoring points 2 to N are selected, the default service of the above-mentioned monitoring point 1 for the target service is Permissions are enabled.

应理解，上述示例仅以未被选中的监控点作为目标监控点为例，进行介绍。当然，也可以选中的监控点作为目标监控点。例如，仍以N个监控点为例，针对某一目标关联对象1而言，若该目标关联对象1针对目标业务的业务权限是开启，且上述N个监控点全部被选中，则默认上述N个监控点针对目标业务的业务权限开启。若该目标关联对象1针对目标业务的业务权限是开启，且上述监控点1被选中，监控点2至监控点N未被选中，则默认上述监控点1针对目标业务的业务权限开启。或者，反之，若该目标关联对象1针对目标业务的业务权限是关闭，且上述N个监控点全部被选中，则默认上述N个监控点针对目标业务的业务权限均开启。若该目标关联对象1在目标业务上的业务权限是关闭，且上述N个监控点中监控点1被选中，监控点2至监控点N未被选中，则默认上述监控点1针对目标业务的业务权限开启。It should be understood that the above example is only described by taking the unselected monitoring point as the target monitoring point as an example. Of course, the selected monitoring point can also be used as the target monitoring point. For example, still taking N monitoring points as an example, for a certain target associated object 1, if the service authority of the target associated object 1 for the target service is enabled, and all the above N monitoring points are selected, the above N monitoring points are defaulted. The business authority of each monitoring point for the target business is enabled. If the service authority of the target associated object 1 for the target service is enabled, and the monitoring point 1 is selected, and monitoring points 2 to N are not selected, then the service authority of the monitoring point 1 for the target service is enabled by default. Or, conversely, if the service authority of the target associated object 1 for the target service is disabled, and all the N monitoring points are selected, the service authority of the N monitoring points for the target service is enabled by default. If the service authority of the target associated object 1 on the target service is closed, and the monitoring point 1 is selected among the above N monitoring points, and the monitoring point 2 to monitoring point N are not selected, then the default monitoring point 1 for the target service. Business permissions are enabled.

其中，S302b的具体实现包括如下示例：The specific implementation of S302b includes the following examples:

示例1b，第一取流请求指示用户甲获取n1路上述监控点1的预览业务流。此种情况下，第一视频流媒体服务平台采用的第二管控策略至少指示：在上述监控点1的视频流中，用户甲针对预览允许的最大取流路数为N3。在原有已请求路数n0的基础上，再新增请求n1路预览视频流后，若n0+n1小于或等于N3，则第一取流请求的校验结果b指示满足第二管控策略的要求。反之，若n0+n1大于N3，则第一取流请求的校验结果b指示不满足第二管控策略的要求。Example 1b, the first stream fetch request instructs user A to obtain n1 preview service streams of the monitoring point 1. In this case, the second management and control strategy adopted by the first video streaming service platform at least indicates that in the video stream of monitoring point 1, the maximum number of streams that User A allows for preview is N3. On the basis of the original number of requested channels n0, after adding a new request for n1 channels of preview video streams, if n0+n1 is less than or equal to N3, the verification result b of the first streaming request indicates that the requirements of the second management and control strategy are met. . Conversely, if n0+n1 is greater than N3, the verification result b of the first flow fetching request indicates that the requirements of the second management and control policy are not met.

应理解，上述示例1b中，n0为正整数。第二管控策略还指示其他关联对象针对监控点1的预览业务的最大取流路数，S302b还对其他关联对象指示的最大取流路数进行校验，可以参见S302的介绍，此处不再一一赘述。It should be understood that in the above example 1b, n0 is a positive integer. The second management and control policy also indicates the maximum number of access paths for the preview service of monitoring point 1 by other associated objects, and S302b also checks the maximum number of access streams indicated by other associated objects. Please refer to the introduction of S302, which is not repeated here. Repeat them one by one.

相应的，在第一视频流媒体服务平台执行S302b的情况下，S303中的目标业务流是满足第二管控策略的视频流。仍以目标监控点实现为上述监控点1为例，第一客户端设备上播放关于监控点1的目标业务流。Correspondingly, when the first video streaming media service platform executes S302b, the target service stream in S303 is a video stream that satisfies the second management and control policy. Still taking the implementation of the target monitoring point as the above-mentioned monitoring point 1 as an example, the first client device plays the target service flow related to the monitoring point 1 .

如此，第一视频视频流媒体服务平台能够通过配置目标监控点的业务权限，来管控对目标监控点的目标业务流的取流行为，使得第一客户端设备上播放满足第二管控策略的目标业务流。In this way, the first video video streaming service platform can control the fetching behavior of the target service stream of the target monitoring point by configuring the service authority of the target monitoring point, so that the first client device can play the target that satisfies the second control strategy. business flow.

需要说明的是，上述管控策略a、管控策略b和管控策略c中的取流路数可以是取流控制系统预先配置的，也可以是由用户(或用户组、或客户端设备)配置的。下面，仅以管控策略a为例，对管控策略a的取流路数确定过程进行介绍，如图6a所示，本申请实施例取流控制方法300还包括S306和S307：It should be noted that the number of flow access paths in the above management and control strategy a, management and control strategy b, and management and control strategy c may be pre-configured by the flow control system, or may be configured by a user (or a user group, or a client device) . In the following, only the management and control strategy a is taken as an example to introduce the process of determining the number of flow paths for the management and control strategy a. As shown in FIG. 6a, theflow control method 300 in this embodiment of the present application further includes S306 and S307:

S306、第一客户端设备向第一视频流媒体服务平台发送取流参数a。相应的，第一视频流媒体服务平台接收来自第一客户端设备的取流参数a。S306: The first client device sends the streaming parameter a to the first video streaming service platform. Correspondingly, the first video streaming service platform receives the streaming parameter a from the first client device.

其中，取流参数a是目标关联对象1被配置的取流参数。示例性的，以关联对象X为关联对象Y配置取流参数为例，关联对象Y是上述某一目标关联对象1。关联对象X和关联对象Y是关联对象a中的部分对象。关联对象X与关联对象Y可以是同一关联对象。例如，关联对象X和关联对象Y均实现为用户，如取流参数a指示用户甲为自身配置取流路数的最大值，以方便用户灵活配置自身的取流参数。或者，关联对象X与关联对象Y也可以是不同关联对象。例如，关联对象X和关联对象Y均实现为用户，如取流参数a指示用户甲为用户乙配置取流路数的最大值，以方便用户为其他用户灵活配置取流参数。The stream access parameter a is the configured stream access parameter of the target associated object 1 . Illustratively, it is taken as an example that the associated object X configures the flow fetching parameter for the associated object Y, and the associated object Y is the above-mentioned certain target associated object 1 . Related object X and related object Y are partial objects in related object a. The related object X and the related object Y may be the same related object. For example, both the associated object X and the associated object Y are implemented as users. For example, the access parameter a instructs the user A to configure the maximum number of access paths for himself, so as to facilitate the user to flexibly configure his own access parameters. Alternatively, the related object X and the related object Y may be different related objects. For example, both the associated object X and the associated object Y are implemented as users. For example, the stream access parameter a instructs user A to configure the maximum number of access streams for user B, so as to facilitate the user to flexibly configure stream access parameters for other users.

应理解，取流参数a指示的取流参数适用于每一种类型的业务。例如，仍以取流参数a指示用户甲为自身配置取流路数的最大值为例，该最大值可以是用户甲针对预览取流路数的最大值，也可以是用户甲针对回放取流路数的最大值，还可以是用户甲针对下载取流路数的最大值。以上仅以关联对象X和关联对象Y均实现为用户为例，进行介绍，关联对象X和关联对象Y也可以实现为用户组、或客户端设备，此处不再一一赘述。It should be understood that the streaming parameter indicated by the streaming parameter a is applicable to each type of service. For example, still take the flow parameter a instructing user A to configure the maximum number of streams for himself as an example, the maximum value can be the maximum number of streams taken by user A for preview, or the maximum number of streams taken by user A for playback. The maximum value of the number of channels may also be the maximum value of the number of streams taken by user A for downloading. The above only takes the example that both the associated object X and the associated object Y are implemented as users for introduction. The associated object X and the associated object Y can also be implemented as user groups or client devices, which will not be repeated here.

示例性的，参见图6b，第一客户端设备向第一视频流媒体服务平台的VSCS组件发送配置管控参数。相应的，第一视频流媒体服务平台的VSCS组件接收来自第一客户端设备的配置管控参数。其中，配置管控参数即为上述取流参数a。Exemplarily, referring to FIG. 6b, the first client device sends the configuration management parameter to the VSCS component of the first video streaming media service platform. Correspondingly, the VSCS component of the first video streaming service platform receives the configuration control parameters from the first client device. The configuration control parameter is the above-mentioned flow acquisition parameter a.

S307、第一视频流媒体服务平台根据取流参数a确定管控策略a中的取流路数。S307: The first video streaming media service platform determines the number of streaming channels in the management and control strategy a according to the streaming parameter a.

示例性的，第一视频流媒体服务平台将取流参数a指示的取值，作为管控策略a中的取流路数。或第一视频流媒体服务平台对取流参数a进行一定的处理，如取流参数a是多个的情况下，将多个取流参数a中的最大值、最小值或平均值，作为管控策略a中的取流路数。Exemplarily, the first video streaming media service platform takes the value indicated by the streaming parameter a as the number of streaming channels in the management and control policy a. Or the first video streaming media service platform performs certain processing on the streaming parameter a. For example, when there are multiple streaming parameters a, the maximum value, the minimum value or the average value among the multiple streaming parameters a is used as the control and control value. The number of access paths in strategy a.

示例性的，参见图6b，VSCS组件存储配置管控参数，如存入数据库，然后，VSCS组件进行筛选，如按照一定的规则从多个配置管控参数中进行筛选，以得到候选参数，基于候选参数，确定候选管控策略中的取流路数，再将候选管控策略发送给VNSC组件，以使VNSC组件保存候选管控策略。VNSC组件和VSCS组件按照一定的规则，从候选管控策略中确定实际运行中采用的管控策略，即上述管控策略a，实现配置同步。Exemplarily, referring to FIG. 6b, the VSCS component stores the configuration control parameters, such as storing them in a database, and then the VSCS component performs screening, such as screening from multiple configuration control parameters according to certain rules, to obtain candidate parameters, based on the candidate parameters. , determine the number of access channels in the candidate management and control strategy, and then send the candidate management and control strategy to the VNSC component, so that the VNSC component saves the candidate management and control strategy. The VNSC component and the VSCS component determine, according to certain rules, the management and control strategy adopted in the actual operation from the candidate management and control strategies, that is, the above-mentioned management and control strategy a, to achieve configuration synchronization.

如此，第一视频流媒体服务平台能够基于第一客户端设备提供的取流参数，来确定管控策略a中的取流路数，增加了管控策略配置的灵活性。In this way, the first video streaming media service platform can determine the number of streaming channels in the management and control strategy a based on the streaming parameters provided by the first client device, which increases the flexibility of the configuration of the management and control strategy.

应理解，S306和S307仅以管控策略a为例进行介绍，当然，管控策略b和管控策略c也可以参见上述过程，此处不再一一赘述。It should be understood that S306 and S307 are only introduced by taking the management and control strategy a as an example. Of course, the management and control strategy b and the management and control strategy c may also refer to the above process, which will not be repeated here.

在一些实施例中，若某一(些)监控点突发紧急情况，这些监控点的业务权限被关闭，以防止上述监控点的指定类型的业务流泄露，如图7所示，本申请实施例取流控制方法300还包括S308和S309：In some embodiments, if an emergency occurs at a certain monitoring point(s), the service authority of these monitoring points is closed to prevent the leakage of the specified type of service flow of the above monitoring points. As shown in FIG. 7 , this application implements For example, theflow control method 300 further includes S308 and S309:

S308、第一视频流媒体服务平台更新管控策略a。S308, the first video streaming media service platform updates the management and control strategy a.

其中，更新后的管控策略a指示拒绝提供目标监控点的指定类型的业务流。指定类型的业务包括至少一种业务，如预览、回放、或下载。示例性的，仍以目标监控点是上述监控点1为例，在指定类型的业务是预览的情况下，监控点1的业务权限从开启更新为关闭，即监控点1的视频流无法被预览。Wherein, the updated management and control policy a indicates that the specified type of service flow of the target monitoring point is refused to be provided. The specified type of service includes at least one service, such as preview, playback, or download. Exemplarily, still taking the above-mentioned monitoring point 1 as an example, when the specified type of service is preview, the service authority of monitoring point 1 is updated from on to off, that is, the video stream of monitoring point 1 cannot be previewed. .

S309、第一视频流媒体服务平台根据更新后的管控策略a，切断针对目标监控点的已提供业务流中的指定类型的业务流。S309: The first video streaming media service platform cuts off the service flow of the specified type in the provided service flow for the target monitoring point according to the updated management and control policy a.

示例性的，第一视频流媒体服务平台不再向第一客户端设备提供监控点1的预览业务流。相应的，第一客户端设备无法预览监控点1的视频流。也就是说，第一视频流媒体服务平台针对监控点设置快捷管控入口，从而快速地收回监控点的业务权限。Exemplarily, the first video streaming service platform no longer provides the first client device with the preview service stream of the monitoring point 1 . Correspondingly, the first client device cannot preview the video stream of the monitoring point 1 . That is to say, the first video streaming media service platform sets a quick control entry for the monitoring point, so as to quickly recover the business authority of the monitoring point.

应理解，第一视频流媒体服务平台也可以针对某一(些)监控点设置关联对象集合，如描述为白名单。一个关联对象集合包括一个或多个关联对象a，关联对象集合中的关联对象a可以是用户、用户组。在该集合内的关联对象能够获取该监控点的指定类型的业务流，其他关联对象无法获取该监控点的指定类型的业务流。或者，反之，该关联对象集合描述为黑名单。在该集合内的关联对象无法获取该监控点的指定类型的业务流，其他关联对象可以获取该监控点的指定类型的业务流。It should be understood that the first video streaming media service platform may also set an associated object set for a certain monitoring point(s), such as a white list described. An associated object set includes one or more associated objects a, and the associated object a in the associated object set may be a user or a user group. The associated objects in the set can obtain the specified type of business flow of the monitoring point, and other associated objects cannot obtain the specified type of business flow of the monitoring point. Or, conversely, the set of associated objects is described as a blacklist. The associated objects in this set cannot obtain the specified type of business flow of the monitoring point, and other associated objects can obtain the specified type of business flow of the monitoring point.

也就是说，第一视频视频流媒体服务平台能够通过配置目标监控点的业务权限，来管控对目标监控点的视频流的取流行为，如目标监控点的业务权限关闭的情况下，第一视频流媒体服务平台不再提供该目标监控点的指定类型的业务流，以防止该目标监控点指定类型的业务流泄露，提高了取流过程管控的灵活性。That is to say, the first video video streaming media service platform can control the fetching behavior of the video stream of the target monitoring point by configuring the business authority of the target monitoring point. For example, when the business authority of the target monitoring point is closed, the first The video streaming media service platform no longer provides the service flow of the specified type of the target monitoring point, so as to prevent the leakage of the service flow of the specified type of the target monitoring point, and improve the flexibility of the management and control of the flow acquisition process.

在一些实施例中，本申请实施例取流控制方法300还能够对云台进行管控。作为一种可能的实现方式，本级云台的管控步骤如图8a所示：In some embodiments, theflow control method 300 according to the embodiment of the present application can also manage and control the PTZ. As a possible implementation, the management and control steps of the PTZ at this level are shown in Figure 8a:

S310、第二客户端设备向第一视频流媒体服务平台发送指令X。相应的，第一视频流媒体服务平台接收来自第二客户端设备的指令X。S310. The second client device sends an instruction X to the first video streaming media service platform. Correspondingly, the first video streaming media service platform receives the instruction X from the second client device.

其中，第二客户端设备与第一客户端设备，可以是同一设备，也可以不同设备，本申请实施例对此不作限定。The second client device and the first client device may be the same device or different devices, which are not limited in this embodiment of the present application.

其中，指令X包括第一关联对象对第一监控点的管控信息。第一关联对象是关联对象a中的一个关联对象，如第一关联对象是关联对象a中的用户，或用户组。Wherein, the instruction X includes management and control information of the first monitoring point by the first associated object. The first associated object is an associated object in the associated object a, for example, the first associated object is a user or a user group in the associated object a.

示例性的，指令X包括用户甲对第一监控点的管控信息，或者，指令X包括用户组1对第一监控点的管控信息。Exemplarily, the instruction X includes the management and control information of the first monitoring point by the user A, or the instruction X includes the management and control information of the first monitoring point by the user group 1 .

应理解，管控信息包括以下至少一项：锁定云台的信息，或操作云台的信息。其中，锁定云台是指，某一用户或权限级别高于该用户的其他用户能够操作该云台，或某一用户组或权限级别高于该用户组的其他用户组能够操作该云台。用户的权限级别和用户组的权限级别是预定义的，如按照公司或机构中组织架构来配置权限级别。示例性的，在管控信息实现为锁定云台的信息的情况下，指令X也可以描述为云台锁定指令。It should be understood that the management and control information includes at least one of the following: information about locking the PTZ, or information about operating the PTZ. Among them, locking the PTZ means that a user or other users with higher authority levels can operate the PTZ, or a user group or other user groups with higher authority levels can operate the PTZ. User permission levels and user group permission levels are predefined, such as configuring permission levels according to the organizational structure in a company or institution. Exemplarily, in the case that the control information is implemented as information for locking the pan/tilt, the instruction X may also be described as a pan/tilt locking instruction.

操作云台是指，响应于用户或用户组的指令，来调整云台的工作状态，如云台的转动速度、云台的俯仰角度等。应理解，对于某一云台而言，若该云台未被锁定，则云台可以响应不同用户或用户组的指令，来调整自身的工作状态。反之，若该云台已被某一权限级别(如权限级别A)的用户锁定，则云台可以响应高于该级别A的用户的指令，来调整自身的工作状态。若云台接收到的指令来自于权限级别A的其他用户，或低于权限级别A的用户，则云台不响应接收到的上述指令，云台的工作状态不发生变化。类似的，上述情况也适用于用户组的权限级别。示例性的，在管控信息实现为操作云台的信息的情况下，指令X也可以描述为云台控制指令。Operating the gimbal refers to adjusting the working state of the gimbal, such as the rotation speed of the gimbal and the pitch angle of the gimbal, in response to the instructions of the user or the user group. It should be understood that, for a certain pan/tilt, if the pan/tilt is not locked, the pan/tilt can adjust its working state in response to instructions from different users or user groups. Conversely, if the pan/tilt has been locked by a user with a certain authority level (eg, authority level A), the pan/tilt can adjust its working state in response to an instruction from a user with a higher level A. If the command received by the PTZ is from another user with permission level A, or a user with lower permission level A, the PTZ will not respond to the above-mentioned command received, and the working status of the PTZ will not change. Similarly, the above also applies to the permission level of the user group. Exemplarily, in the case where the management and control information is implemented as information for operating the pan/tilt, the instruction X may also be described as a pan/tilt control instruction.

其中，第一监控点包括支撑图像采集设备。图像采集设备用于采集视频流。示例性的，以图2中的曲线a所示的场景为例，第一视频流媒体服务平台实现为本域视频流媒体服务平台100，第一监控点上的云台可以与本域视频流媒体服务平台100通信连接。相应的，第一监控点上的图像采集设备是本域前端设备集群102。以图2中的曲线c所示的场景为例，第一视频流媒体服务平台实现为本域视频流媒体服务平台100，第二视频流媒体服务平台实现为第二邻域视频流媒体服务平台120，第一监控点上的云台可以与第二邻域视频流媒体服务平台120通信连接。相应的，第一监控点上的图像采集设备是第二邻域前端设备集群122。Wherein, the first monitoring point includes a supporting image acquisition device. Image capture devices are used to capture video streams. Exemplarily, taking the scenario shown by the curve a in FIG. 2 as an example, the first video streaming media service platform is implemented as the local video streamingmedia service platform 100, and the PTZ on the first monitoring point can be connected with the local video streaming service platform. Themedia service platform 100 is communicatively connected. Correspondingly, the image acquisition device on the first monitoring point is the local front-end device cluster 102 . Taking the scenario shown by the curve c in FIG. 2 as an example, the first video streaming media service platform is implemented as the local video streamingmedia service platform 100, and the second video streaming media service platform is implemented as the second neighborhood video streaming media service platform. 120. The PTZ on the first monitoring point can be connected in communication with the second neighborhood video streamingmedia service platform 120. Correspondingly, the image acquisition device on the first monitoring point is the second neighborhood front-end device cluster 122 .

示例性的，参见图8b，指令X实现为云台锁定指令。第二客户端设备向第一视频流媒体服务平台的DAC组件发送云台锁定指令。相应的，第一视频流媒体服务平台通过DAC组件接收来自第二客户端设备的云台锁定指令。参见图8c，指令X实现为云台控制指令。第二客户端设备向第一视频流媒体服务平台的DAC组件发送云台控制指令。相应的，第一视频流媒体服务平台通过DAC组件接收来自第二客户端设备的云台控制指令。其中，图8b和图8c仅以本级云台管控为例进行介绍。在本申请实施例中，本级云台，可以理解为，被管控的云台与发送云台锁定指令(或云台锁定指令)的客户端设备接入同一服务平台。Exemplarily, referring to Fig. 8b, the instruction X is implemented as a pan/tilt lock instruction. The second client device sends a PTZ locking instruction to the DAC component of the first video streaming service platform. Correspondingly, the first video streaming service platform receives the PTZ locking instruction from the second client device through the DAC component. Referring to Fig. 8c, the instruction X is implemented as a PTZ control instruction. The second client device sends a PTZ control instruction to the DAC component of the first video streaming service platform. Correspondingly, the first video streaming service platform receives the PTZ control instruction from the second client device through the DAC component. Among them, Fig. 8b and Fig. 8c only take the PTZ management and control of this level as an example for introduction. In the embodiment of the present application, the PTZ at this level can be understood as that the PTZ under control and the client device that sends the PTZ locking instruction (or the PTZ locking instruction) access the same service platform.

参见图8d，指令X实现为云台锁定指令。第二客户端设备向第一视频流媒体服务平台的本级NCG组件发送云台锁定指令。相应的，第一视频流媒体服务平台通过本级NCG组件接收来自第二客户端设备的云台锁定指令。参见图8e，指令X实现为云台控制指令。第二客户端设备向第一视频流媒体服务平台的本级NCG组件发送云台控制指令。相应的，第一视频流媒体服务平台通过本级NCG组件接收来自第二客户端设备的云台控制指令。其中，图8d和图8e仅以跨级云台管控为例进行介绍。在本申请实施例中，跨级云台，可以理解为，被管控的云台与发送云台锁定指令(或云台锁定指令)的客户端设备接入不同的服务平台。Referring to Fig. 8d, the command X is implemented as a gimbal locking command. The second client device sends a PTZ locking instruction to the NCG component at the current level of the first video streaming service platform. Correspondingly, the first video streaming service platform receives the PTZ locking instruction from the second client device through the NCG component at the same level. Referring to Fig. 8e, the instruction X is implemented as a PTZ control instruction. The second client device sends a PTZ control instruction to the NCG component at the current level of the first video streaming service platform. Correspondingly, the first video streaming service platform receives the PTZ control instruction from the second client device through the NCG component at the same level. Among them, FIG. 8d and FIG. 8e only take the cross-level PTZ management and control as an example for introduction. In the embodiment of the present application, the cross-level PTZ can be understood as that the PTZ under management and the client device that sends the PTZ locking instruction (or the PTZ locking instruction) access different service platforms.

S311、第一视频流媒体服务平台对指令X进行校验，以得到指令X的校验结果。S311. The first video streaming media service platform verifies the instruction X to obtain a verification result of the instruction X.

示例性的，第一视频流媒体服务平台确定第一关联对象对第一监控点的访问权限是否开启，以及确定第一监控点是否被其他关联对象锁定。其中，其他关联对象的权限级别高于第一关联对象的权限级别。Exemplarily, the first video streaming service platform determines whether the access authority of the first associated object to the first monitoring point is enabled, and determines whether the first monitoring point is locked by other associated objects. The permission level of other associated objects is higher than the permission level of the first associated object.

参见图8b或图8c，如第一视频流媒体服务平台所在的虚线方框所示，VSCS组件校验是否使能。具体地，VSCS组件确定第一关联对象对第一监控点的访问权限是否开启，若不开启，则VSCS组件的校验结果指示不通过。反之，若开启，则VSCS组件的校验结果指示通过。在VSCS组件的校验结果指示通过的情况下，DAC组件进行权限校验，具体地，DAC组件确定第一监控点是否被其他关联对象锁定，若是，则DAC组件的校验结果指示不通过。反之，若否，则DAC组件的校验结果指示通过。Referring to Fig. 8b or Fig. 8c, as shown in the dotted box where the first video streaming service platform is located, the VSCS component checks whether it is enabled. Specifically, the VSCS component determines whether the access authority of the first associated object to the first monitoring point is enabled, and if it is not enabled, the verification result of the VSCS component indicates that it fails. On the contrary, if it is turned on, the verification result of the VSCS component indicates that it is passed. When the verification result of the VSCS component indicates a pass, the DAC component performs authority verification. Specifically, the DAC component determines whether the first monitoring point is locked by other associated objects, and if so, the verification result of the DAC component indicates that it fails. Conversely, if not, the verification result of the DAC component indicates a pass.

参见图8d或图8e，如第一视频流媒体服务平台所在的虚线方框所示，VSCS组件校验是否使能，以及权限校验。其中，检验是否使能，以及权限校验的介绍可以参见图8b或图8c，此处不再赘述。Referring to Fig. 8d or Fig. 8e, as shown in the dotted box where the first video streaming media service platform is located, the VSCS component checks whether it is enabled, and checks the authority. The description of whether the verification is enabled and the permission verification may refer to FIG. 8b or FIG. 8c, and details are not repeated here.

其中，访问权限开启，可以理解为，第一关联对象拥有对第一监控点的访问权限。访问权限关闭，可以理解为，第一关联对象不具有对第一监控点的访问权限。Wherein, when the access authority is enabled, it can be understood that the first associated object has the access authority to the first monitoring point. When the access authority is closed, it can be understood that the first associated object does not have the access authority to the first monitoring point.

其中，指令X的校验结果包括如下四种情况：Among them, the verification result of instruction X includes the following four cases:

情况a1，第一关联对象对第一监控点的访问权限开启，且第一监控点未被其他关联对象锁定。In case a1, the access authority of the first associated object to the first monitoring point is enabled, and the first monitoring point is not locked by other associated objects.

情况b1，第一关联对象对第一监控点的访问权限开启，但第一监控点已被其他关联对象锁定。In case b1, the access authority of the first associated object to the first monitoring point is enabled, but the first monitoring point has been locked by other associated objects.

情况c1，第一关联对象对第一监控点的访问权限关闭，且第一监控点未被其他关联对象锁定。In case c1, the access authority of the first associated object to the first monitoring point is closed, and the first monitoring point is not locked by other associated objects.

情况d1，第一关联对象对第一监控点的访问权限关闭，但第一监控点已被其他关联对象锁定。In case d1, the access authority of the first associated object to the first monitoring point is closed, but the first monitoring point has been locked by other associated objects.

应理解，第一视频流媒体服务平台可以先确定访问权限是否开启，再确定是否被其他关联对象锁定。或者，第一视频流媒体服务平台可以先确定是否被其他关联对象锁定，再确定访问权限是否开启。或者，第一视频流媒体服务平台可以同时确定是否被其他关联对象锁定，以及访问权限是否开启，本申请实施例对此不作限定。每个关联对象对第一监控点的访问权限可以是取流控制系统预配置的。示例性的，表3示出了各个关联对象在云台上的访问权限。It should be understood that the first video streaming media service platform may first determine whether the access authority is enabled, and then determine whether it is locked by other associated objects. Alternatively, the first video streaming service platform may first determine whether it is locked by other associated objects, and then determine whether the access authority is enabled. Alternatively, the first video streaming media service platform may simultaneously determine whether it is locked by other associated objects and whether the access authority is enabled, which is not limited in this embodiment of the present application. The access authority of each associated object to the first monitoring point may be pre-configured by the flow control system. Exemplarily, Table 3 shows the access rights of each associated object on the PTZ.

表3table 3

关联对象associated object目标业务target business访问权限access permission联网系统networking system云台控制PTZ control开启、关闭open close用户user云台控制PTZ control开启、关闭open close用户组user group云台控制PTZ control开启、关闭open close

在表3中，关联对象有3种，包括联网系统、用户和用户组。目标业务包括云台控制。访问权限有2种，包括开启和关闭。示例性的，以用户所在行为例，某一用户在云台控制业务上的访问权限可以是开启，即该用户能够对云台进行管控。某一用户在预览业务上的业务权限也可以是关闭，即该用户无法对云台进行管控。其他关联对象的访问权限介绍可以参见表3，此处不再一一赘述。In Table 3, there are three types of associated objects, including networked systems, users and user groups. The target business includes PTZ control. There are 2 types of access rights, including on and off. Exemplarily, taking the user's house as an example, the access authority of a certain user on the PTZ control service may be enabled, that is, the user can manage and control the PTZ. The service authority of a user in the preview service can also be disabled, that is, the user cannot control the PTZ. For the introduction of the access rights of other associated objects, please refer to Table 3, which will not be repeated here.

示例性的，作为一种可能的实施例，云台控制与第一管控策略可以在同一预案中配置，如表2所示的预案中，还指示了关联对象对第一监控点的访问权限。Exemplarily, as a possible embodiment, the pan-tilt control and the first management and control strategy may be configured in the same plan. As shown in Table 2, the plan also indicates the access authority of the associated object to the first monitoring point.

若指令X的校验结果实现为上述情况b1、情况c1或情况d1，则第一视频流媒体服务平台执行S312，如图8a中示例1所在的方框所示。若指令X的校验结果实现为上述情况a1，且第一监控点上的云台与第一视频流媒体服务平台通信连接，则第一视频流媒体服务平台执行S313，如图8a中示例1所在的方框所示。若指令X的校验结果实现为上述情况a1，且第一监控点上的云台与第二视频流媒体服务平台通信连接，则第一视频流媒体服务平台执行S314，如图8a中示例2所在的方框所示。其中，S312至S314的介绍如下：If the verification result of the instruction X is realized as the above-mentioned case b1, case c1 or case d1, the first video streaming media service platform executes S312, as shown in the block of Example 1 in FIG. 8a. If the verification result of the instruction X is realized as the above-mentioned situation a1, and the PTZ on the first monitoring point is communicatively connected to the first video streaming media service platform, the first video streaming media service platform executes S313, as shown in Example 1 in Figure 8a shown in the box. If the verification result of the instruction X is realized as the above situation a1, and the PTZ on the first monitoring point is in communication connection with the second video streaming media service platform, then the first video streaming media service platform executes S314, as shown in Example 2 in Figure 8a shown in the box. Among them, the introduction of S312 to S314 is as follows:

S312、第一视频流媒体服务平台向第二客户端设备发送拒绝信息。相应的，第二客户端设备接收来自第一视频流媒体服务平台的拒绝信息。S312. The first video streaming media service platform sends rejection information to the second client device. Correspondingly, the second client device receives the rejection information from the first video streaming service platform.

其中，拒绝信息指示对第一监控点的管控无效，如图8b和图8c所示的错误码。The rejection information indicates that the control of the first monitoring point is invalid, such as the error codes shown in FIG. 8b and FIG. 8c.

此种情况下，第一监控点上云台的工作状态不发生变化。In this case, the working state of the gimbal on the first monitoring point does not change.

在一些实施例中，云台与监控点存在对应关系，若某一(些)监控点突发紧急情况，这些监控点的云台访问权限被关闭，以防止上述监控点的云台被恶意用户操作，所以，第一视频流媒体服务平台针对监控点设置快捷管控入口，从而快速收回云台管控权限。如此，第一视频视频流媒体服务平台能够通过配置第一监控点的访问权限，来管控第一监控点，如某一监控点有突发紧急情况时，部分关联对象或全部关联对象对该监控点上第一监控点的访问权限设置为关闭，以避免不必要的关联对象或恶意的关联对象操控该监控点上的第一监控点。和/或，在第一监控点被权限级别更高的关联对象锁定的情况下，第一视频流媒体服务平台不再基于指令X来控制第一监控点，以便于权限级别更高的关联对象来操控第一监控点。In some embodiments, there is a corresponding relationship between the PTZ and the monitoring points. If an emergency occurs at a certain monitoring point(s), the PTZ access rights of these monitoring points are closed to prevent the PTZ of the monitoring point from being used by malicious users. Therefore, the first video streaming service platform sets up a quick control entry for the monitoring point, so as to quickly recover the PTZ control authority. In this way, the first video video streaming media service platform can manage and control the first monitoring point by configuring the access authority of the first monitoring point. If there is an emergency at a certain monitoring point, some or all of the related objects will monitor the monitoring point. The access authority of the first monitoring point on the point is set to be off, so as to prevent unnecessary associated objects or malicious associated objects from manipulating the first monitoring point on the monitoring point. And/or, in the case where the first monitoring point is locked by an associated object with a higher authority level, the first video streaming service platform no longer controls the first monitoring point based on the instruction X, so as to facilitate the associated object with a higher authority level. to control the first monitoring point.

S313、第一视频流媒体服务平台响应于指令X，控制第一监控点。S313: The first video streaming media service platform controls the first monitoring point in response to the instruction X.

示例性的，参见图8b，如第一视频流媒体服务平台所在的虚线方框所示，DAC组件向第一监控点的云台1发送锁定云台的信息，以锁定云台1。Exemplarily, referring to FIG. 8b , as shown by the dotted box where the first video streaming service platform is located, the DAC component sends the information of locking the PTZ to the PTZ 1 of the first monitoring point, so as to lock the PTZ 1 .

参见图8c，如第一视频流媒体服务平台所在的虚线方框所示，DAC组件向第一监控点的云台1发送操作指令，以操作第一监控点的云台1，如操作指令指示云台1的转动速度、转动时长等信息，以调整云台1的工作状态。Referring to Fig. 8c, as shown in the dotted box where the first video streaming service platform is located, the DAC component sends an operation instruction to the PTZ 1 of the first monitoring point to operate the PTZ 1 of the first monitoring point, as indicated by the operation instruction Information such as the rotation speed and rotation duration of the gimbal 1 to adjust the working state of the gimbal 1 .

如此，即可对本级云台进行管控。In this way, the PTZ at this level can be managed and controlled.

S314、第一视频流媒体服务平台向第二视频流媒体服务平台发送指令Y。相应的，第二视频流媒体服务平台接收来自第一视频流媒体服务平台的指令Y。S314: The first video streaming media service platform sends the instruction Y to the second video streaming media service platform. Correspondingly, the second video streaming media service platform receives the instruction Y from the first video streaming media service platform.

其中，指令Y包括第一视频流媒体服务平台对第一监控点的管控信息。第一监控点和管控信息可以参见指令X的介绍，此处不再赘述。Wherein, the instruction Y includes the management and control information of the first monitoring point by the first video streaming service platform. For the first monitoring point and the management and control information, reference may be made to the introduction of the instruction X, which will not be repeated here.

示例性的，参见图8d或图8e，如第一视频流媒体服务平台所在的虚线方框所示，VSCS组件的校验结果指示通过的情况下，VSCS组件通过本级级联组件和中间级级联组件向第二视频流媒体服务平台的VSCS组件发送指令Y。Exemplarily, referring to FIG. 8d or FIG. 8e, as shown in the dashed box where the first video streaming service platform is located, when the verification result of the VSCS component indicates that it is passed, the VSCS component passes through the cascading component of this level and the intermediate level. The cascade component sends instruction Y to the VSCS component of the second video streaming service platform.

S315、第二视频流媒体服务平台对指令Y进行校验，以得到指令Y的校验结果。S315 , the second video streaming media service platform verifies the instruction Y to obtain the verification result of the instruction Y.

示例性的，第二视频流媒体服务平台确定第一视频流媒体服务平台对第一监控点的访问权限是否开启，以及确定第一监控点是否被其他关联对象锁定。Exemplarily, the second video streaming media service platform determines whether the access authority of the first video streaming media service platform to the first monitoring point is enabled, and determines whether the first monitoring point is locked by other associated objects.

参见图8d或图8e，如第二视频流媒体服务平台所在的虚线方框所示，VSCS组件校验是否使能，以及权限校验。其中，检验是否使能，以及权限校验的介绍可以参见图8b或图8c，此处不再赘述。Referring to FIG. 8d or FIG. 8e , as shown in the dotted box where the second video streaming media service platform is located, the VSCS component checks whether it is enabled, and the authority checks. The description of whether the verification is enabled and the permission verification may refer to FIG. 8b or FIG. 8c, and details are not repeated here.

其中，指令Y的校验结果包括如下四种情况：Among them, the verification result of instruction Y includes the following four cases:

情况a2，第一视频流媒体服务平台对第一监控点的访问权限开启，且第一监控点未被其他关联对象锁定。In case a2, the access authority of the first video streaming media service platform to the first monitoring point is enabled, and the first monitoring point is not locked by other associated objects.

情况b2，第一视频流媒体服务平台对第一监控点的访问权限开启，但第一监控点已被其他关联对象锁定。In case b2, the access authority of the first video streaming media service platform to the first monitoring point is enabled, but the first monitoring point has been locked by other associated objects.

情况c2，第一视频流媒体服务平台对第一监控点的访问权限关闭，且第一监控点未被其他关联对象锁定。In case c2, the access authority of the first video streaming service platform to the first monitoring point is closed, and the first monitoring point is not locked by other associated objects.

情况d2，第一视频流媒体服务平台对第一监控点的访问权限关闭，但第一监控点已被其他关联对象锁定。In case d2, the access authority of the first video streaming media service platform to the first monitoring point is closed, but the first monitoring point has been locked by other associated objects.

应理解，第二视频流媒体服务平台可以先确定访问权限是否开启，再确定是否被其他关联对象锁定。或者，第二视频流媒体服务平台可以先确定是否被其他关联对象锁定，再确定访问权限是否开启。或者，第二视频流媒体服务平台可以同时确定是否被其他关联对象锁定，以及访问权限是否开启，本申请实施例对此不作限定。It should be understood that the second video streaming service platform may first determine whether the access authority is enabled, and then determine whether it is locked by other associated objects. Alternatively, the second video streaming service platform may first determine whether it is locked by other associated objects, and then determine whether the access authority is enabled. Alternatively, the second video streaming media service platform may simultaneously determine whether it is locked by other associated objects and whether the access authority is enabled, which is not limited in this embodiment of the present application.

若指令Y的校验结果实现为上述情况b2、情况c2或情况d2，则第二视频流媒体服务平台执行S316。若指令Y的校验结果实现为上述情况a2，且第一监控点的云台与第二视频流媒体服务平台通信连接，则第二视频流媒体服务平台执行S317。其中，S316和S317的介绍如下：If the verification result of the instruction Y is realized as the above-mentioned case b2, case c2 or case d2, the second video streaming media service platform executes S316. If the verification result of the instruction Y is realized as the above situation a2, and the PTZ of the first monitoring point is in communication connection with the second video streaming media service platform, the second video streaming media service platform executes S317. Among them, the introduction of S316 and S317 is as follows:

S316、第二视频流媒体服务平台向第一视频流媒体服务平台发送拒绝信息。相应的，第一视频流媒体服务平台接收来自第二视频流媒体服务平台的拒绝信息。S316. The second video streaming media service platform sends rejection information to the first video streaming media service platform. Correspondingly, the first video streaming media service platform receives rejection information from the second video streaming media service platform.

其中，拒绝信息指示对第一监控点的管控无效，如图8d和图8e所示的错误码。The rejection information indicates that the control of the first monitoring point is invalid, such as the error codes shown in FIG. 8d and FIG. 8e.

对于第一视频流媒体服务平台而言，执行S316之后，执行S312，以向第二客户端设备反馈拒绝信息。For the first video streaming media service platform, after S316 is performed, S312 is performed to feed back rejection information to the second client device.

此种情况下，第一监控点的云台工作状态不发生变化。In this case, the working state of the PTZ of the first monitoring point does not change.

S317、第二视频流媒体服务平台响应于指令Y，控制第一监控点。S317: The second video streaming media service platform controls the first monitoring point in response to the instruction Y.

其中，S317的实现过程可以参见S312的介绍，此处不再赘述。The implementation process of S317 may refer to the introduction of S312, which will not be repeated here.

如此，即可对跨级云台进行管控。In this way, the cross-level PTZ can be managed and controlled.

应理解，图8d和图8e中，仅以三级服务平台为例，对跨级云台管控进行介绍，在执行S315之后，若指令Y的校验结果实现为上述情况a2，则第二视频流媒体服务平台向第三视频流媒体服务平台发送指令Z。相应的，第三视频流媒体服务平台接收来自第二视频流媒体服务平台的指令Z。其中，指令Z包括第二视频流媒体服务平台对第一监控点的管控信息。第一监控点和管控信息可以参见指令X的介绍。第三视频流媒体服务平台对指令Z进行校验，然后，基于指令Z的校验结果对第一监控点进行管控。It should be understood that in FIG. 8d and FIG. 8e, only the three-level service platform is taken as an example to introduce the cross-level PTZ management and control. After executing S315, if the verification result of the instruction Y is realized as the above situation a2, then the second video The streaming media service platform sends the instruction Z to the third video streaming media service platform. Correspondingly, the third video streaming media service platform receives the instruction Z from the second video streaming media service platform. Wherein, the instruction Z includes the management and control information of the first monitoring point by the second video streaming service platform. For the first monitoring point and control information, please refer to the introduction of instruction X. The third video streaming service platform verifies the instruction Z, and then controls the first monitoring point based on the verification result of the instruction Z.

在一些实施例中，本申请实施例取流控制方法300还能够在安全方面对取流行为进行管控，具体步骤如图9a所示：In some embodiments, the flow fetchingcontrol method 300 according to the embodiment of the present application can also manage and control the flow fetching behavior in terms of security, and the specific steps are shown in FIG. 9a :

S318、第一视频流媒体服务平台根据第一信息中的第一策略，在目标业务流中加载水印信息。S318: The first video streaming media service platform loads watermark information in the target service stream according to the first policy in the first information.

其中，第一信息指示第二关联对象被配置的水印策略，以及第二关联对象的优先级。第二关联对象是关联对象a中的至少一个关联对象。The first information indicates the configured watermark policy of the second associated object and the priority of the second associated object. The second associated object is at least one associated object in the associated object a.

水印策略，用于指示目标业务流中加载水印信息的方式。示例性的，加载水印信息的方式，包括以下至少一项：调阅者名称、调阅者ID、监控点名称、IP、实施时间、自定义文本、水印显示方式等。其中，水印显示方式包括字体大小、字体颜色、不透明度以及旋转角度和布局、亮暗程度等。The watermark policy is used to indicate the way of loading watermark information in the target service flow. Exemplarily, the method of loading watermark information includes at least one of the following: caller name, caller ID, monitoring point name, IP, implementation time, custom text, watermark display mode, and the like. Among them, the watermark display mode includes font size, font color, opacity, rotation angle and layout, brightness and darkness, etc.

示例性的，参见表4，表4示出了多种水印策略。For example, see Table 4, which shows various watermarking strategies.

表4Table 4

在表4中，关联对象有5种，包括联网系统、应用、用户、用户组和客户端设备。5种关联对象对应的水印策略在内容上包括：调用方ID，调用方名称，监控点名称，IP地址，实时时间和自定义文本。水印策略在显示配置上均包括字体颜色，字体大小，透明度，旋转角度和布局等。In Table 4, there are five types of associated objects, including networked systems, applications, users, user groups, and client devices. The watermark policies corresponding to the five associated objects include: caller ID, caller name, monitoring point name, IP address, real-time time and custom text. The watermark strategy includes font color, font size, transparency, rotation angle and layout, etc. in the display configuration.

在关联对象a中，每个关联对象或部分关联对象被配置水印策略。不同关联对象被配置的水印策略可以不同。例如，用户甲意图预览的目标业务流中加载有用户甲的信息，如用户甲的名称。用户乙意图预览的目标业务流中加载有用户乙的信息，如用户乙的名称。或者，不同关联对象被配置的水印策略可以相同。例如，用户甲意图预览的视频流，与用户乙意图预览的视频流，均源自同一监控点的前端设备，如均源自本域前端设备集群102。用户甲与用户乙预览的视频流中均加载有同一监控点的信息，如该监控点的名称，或该监控点上的本域前端设备集群102的名称。In the associated object a, each associated object or part of the associated objects is configured with a watermark policy. The watermark policies configured for different associated objects can be different. For example, the target business flow that User A intends to preview is loaded with information of User A, such as User A's name. The target business flow that user B intends to preview is loaded with information of user B, such as the name of user B. Alternatively, the configured watermark policies for different associated objects may be the same. For example, the video stream intended to be previewed by user A and the video stream intended to be previewed by user B both originate from the front-end device at the same monitoring point, for example, both originate from the front-end device cluster 102 in the local domain. The video streams previewed by user A and user B are loaded with information of the same monitoring point, such as the name of the monitoring point, or the name of the local front-end device cluster 102 on the monitoring point.

优先级，用于指示水印信息加载过程中，第二关联对象被配置的水印策略的重要程度。一个关联对象被配置的优先级越高，该关联对象被配置的水印策略的重要程度越高。例如，仍以用户甲和用户乙预览源自本域前端设备集群102的视频流为例，涉及的关联对象包括用户(如上述用户甲和用户乙)和前端设备(如上述本域前端设备集群102)。The priority is used to indicate the importance of the watermark policy configured on the second associated object during the watermark information loading process. The higher the priority of an associated object is configured, the higher the importance of the watermark policy configured for the associated object. For example, still take user A and user B to preview the video stream originating from the front-end device cluster 102 in the domain as an example, the related objects involved include users (such as the above-mentioned user A and user B) and front-end devices (such as the above-mentioned local front-end device cluster) 102).

用户这一关联对象被配置的水印策略包括：在目标业务流中加载意图预览该视频流的用户信息。此种情况下，以取流请求1为例，取流请求1中携带用户的信息，且该用户是采用第一客户端设备发送取流请求1，且意图预览视频流的用户。第一视频流媒体服务平台需区分哪一用户的取流请求1。例如，若用户甲预览某一视频流，则第一视频流媒体服务平台响应于用户甲的取流请求1，该目标业务流中加载有用户甲的信息，如用户甲的名称。若用户乙预览某一视频流，则第一视频流媒体服务平台响应于用户乙的取流请求1，该目标业务流中加载有用户乙的信息，如用户乙的名称。The watermark policy configured for the associated object of the user includes: loading the user information intended to preview the video stream in the target service stream. In this case, taking streaming request 1 as an example, streaming request 1 carries user information, and the user is a user who uses the first client device to send streaming request 1 and intends to preview the video stream. The first video streaming media service platform needs to distinguish which user has the streaming request 1 . For example, if user A previews a certain video stream, the first video streaming media service platform responds to user A's streaming request 1, and the target service stream is loaded with user A's information, such as user A's name. If user B previews a certain video stream, the first video streaming media service platform responds to user B's streaming request 1, and the target service stream is loaded with user B's information, such as user B's name.

前端设备这一关联对象被配置的水印策略包括：在目标业务流中加载前端设备的信息。此种情况下，以取流请求2为例，取流请求2中携带前端设备的信息，且该前端设备用于提供取流请求2意图获取的目标业务流。第一视频流媒体服务平台无需区分哪一用户的取流请求2，关注前端设备即可。例如，用户甲意图预览的目标业务流，与用户乙意图预览的目标业务流，均源自同一监控点的前端设备，如均源自本域前端设备集群102。用户甲与用户乙预览的目标业务流中均加载有同一监控点的信息，如该监控点的名称，或该监控点上的本域前端设备集群102的名称。The watermark policy configured for the associated object of the front-end device includes: loading the information of the front-end device in the target service flow. In this case, taking the flow request 2 as an example, the flow request 2 carries the information of the front-end device, and the front-end device is used to provide the target service flow that the flow request 2 intends to acquire. The first video streaming media service platform does not need to distinguish which user's streaming request 2, and only needs to pay attention to the front-end device. For example, the target service flow that user A intends to preview and the target service flow that user B intends to preview both originate from front-end devices at the same monitoring point, for example, both originate from the front-end device cluster 102 in the domain. The target service flows previewed by user A and user B are loaded with information of the same monitoring point, such as the name of the monitoring point, or the name of the front-end device cluster 102 in the domain on the monitoring point.

其中，第一策略是满足优先级条件的第二关联对象所被配置的水印策略。示例性的，优先级条件包括：每两个优先级中选择较高的优先级，每三个或更多优先级中选择最高的优先级，每三个或更多优先级中选择次高的优先级。优先级条件也可以有更多示例，此处不再一一赘述。下面，仅以优先级条件实现为每两个优先级中选择较高的优先级为例，进行介绍：仍以上述用户和前端设备这两个关联对象被配置的水印策略为例，若用户的优先级高于前端设备的优先级，则第一策略是用户这一关联对象的水印策略。第一视频流媒体服务平台按照用户这一关联对象的水印策略来加载水印信息，无需按照前端设备这一关联对象的水印策略来加载水印信息。若用户的优先级低于前端设备的优先级，则第一策略是前端设备这一关联对象的水印策略。第一视频流媒体服务平台无需按照用户这一关联对象的水印策略来加载水印信息，而是按照前端设备这一关联对象的水印策略来加载水印信息。The first policy is a watermark policy configured for the second associated object that satisfies the priority condition. Exemplarily, the priority conditions include: selecting a higher priority among every two priorities, selecting a highest priority among every three or more priorities, and selecting a second highest priority among every three or more priorities. priority. There may also be more examples of priority conditions, which will not be repeated here. In the following, only the priority condition is implemented to select the higher priority among the two priorities as an example to introduce: still take the watermark policy configured on the two associated objects of the user and the front-end device as an example, if the user's If the priority is higher than that of the front-end device, the first policy is the watermark policy of the associated object of the user. The first video streaming service platform loads the watermark information according to the watermark policy of the associated object of the user, and does not need to load the watermark information according to the watermark policy of the associated object of the front-end device. If the priority of the user is lower than the priority of the front-end device, the first policy is the watermark policy of the associated object of the front-end device. The first video streaming service platform does not need to load the watermark information according to the watermark policy of the associated object of the user, but loads the watermark information according to the watermark policy of the associated object of the front-end device.

示例性的，参见图9b，以全部关联对象a为例，第一视频流媒体服务平台按照每个关联对象a的优先级，对关联对象a进行排序。首先，针对优先级最高的关联对象a，第一视频流媒体服务平台确定该关联对象a是否配置有水印策略。若是，则该关联对象a被配置的水印策略即为上述第一策略。第一视频流媒体服务平台按照此水印策略来加载水印信息。反之，若该关联对象a未配置水印策略，则第一视频流媒体服务平台按照优先级的排列顺序，确定是否存在下一个关联对象a。若是，则第一视频流媒体服务平台将下一个关联对象a确定为当前的关联对象，再次确定当前的关联对象是否配置有水印策略，若是，则按照优先级次高的关联对象a被配置的水印策略来加载水印，若否，则确定是否存在下一个关联对象。如此循环，直至下一个关联对象不存在，此种情况下，第一视频流媒体服务平台无需在目标业务流中加载水印信息。Exemplarily, referring to FIG. 9b, taking all the associated objects a as an example, the first video streaming media service platform sorts the associated objects a according to the priority of each associated object a. First, for the associated object a with the highest priority, the first video streaming service platform determines whether the associated object a is configured with a watermark policy. If so, the watermarking strategy configured for the associated object a is the above-mentioned first strategy. The first video streaming service platform loads the watermark information according to the watermark policy. On the contrary, if the associated object a is not configured with a watermark policy, the first video streaming media service platform determines whether there is a next associated object a according to the priority order. If so, then the first video streaming media service platform determines the next associated object a as the current associated object, and determines again whether the current associated object is configured with a watermark policy, if so, according to the second highest priority associated object a is configured. watermark strategy to load the watermark, if not, determine if there is the next associated object. This cycle is repeated until the next associated object does not exist. In this case, the first video streaming media service platform does not need to load watermark information in the target service stream.

应理解，在本申请实施例中，满足管控策略a，可以理解为，满足每个目标关联对象1的管控策略。例如，目标关联对象1为一个。相应的，管控策略为一个。满足管控策略a，可以理解为，满足一个管控策略。再如，目标关联对象1为至少两个。相应的，管控策略为至少两个，且与目标关联对象1的数量一致。满足管控策略a，可以理解为，满足至少两个管控策略中的全部。满足管控策略b，以及满足管控策略c的理解，可以此类推，不再赘述。It should be understood that, in the embodiment of the present application, satisfying the management and control strategy a can be understood as satisfying the management and control strategy of each target associated object 1 . For example, target associated object 1 is one. Correspondingly, the control strategy is one. Satisfying the management and control strategy a can be understood as satisfying a management and control strategy. For another example, there are at least two target associated objects 1 . Correspondingly, there are at least two management and control strategies, which are consistent with the number of target associated objects 1 . Satisfying the management and control strategy a can be understood as satisfying all of at least two management and control strategies. The understanding of satisfying management and control strategy b and satisfying management and control strategy c can be deduced by analogy, and will not be repeated here.
