技术领域technical field
本申请涉及无线通信技术领域，尤其涉及一种调节蓝牙A2DP(AdvancedDistribution Profile，简称A2DP)编码设置的方法和装置。The present application relates to the technical field of wireless communication, and in particular to a method and a device for adjusting Bluetooth A2DP (Advanced Distribution Profile, A2DP for short) encoding settings.
背景技术Background technique
蓝牙技术是一种工作在2.4GHz频段的无线通信技术，蓝牙技术的出现，使得用户可以通过蓝牙技术来听音乐。其实现原理为：当源端设备(Source，简称SRC，例如，可以是智能电视)与接收端设备(Sink，简称SNK，例如，可以是蓝牙音箱)建立AVDTP(Audio/videoDistribution Transport Protocol，简称AVDTP)链路后，源端设备对音频数据进行编码，然后将音频数据通过两个设备之间建立的AVDTP链路发送给接收端设备，接收端设备收到音频数据后，进行解码播放。在通过蓝牙技术播放音乐时，为保证高品质的音质，源端设备的编码设置显得尤其重要。Bluetooth technology is a wireless communication technology working in the 2.4GHz frequency band. The emergence of Bluetooth technology enables users to listen to music through Bluetooth technology. The realization principle is: when the source device (Source, referred to as SRC, for example, it can be a smart TV) and the receiver device (Sink, referred to as SNK, for example, it can be a Bluetooth speaker) establish an AVDTP (Audio/videoDistribution Transport Protocol, referred to as AVDTP ) link, the source device encodes the audio data, and then sends the audio data to the receiver device through the AVDTP link established between the two devices, and the receiver device decodes and plays the audio data after receiving it. When playing music through Bluetooth technology, in order to ensure high-quality sound quality, the encoding settings of the source device are particularly important.
目前，源端设备一般按照如下方法来确定编码设置，该方法包括：获取接收端设备所支持的编码信息，在源端设备和接收端设备均支持的编码信息中，选择高音质编码设置(低失真率，高码率)作为当前编码设置。At present, the source device generally determines the encoding setting according to the following method. The method includes: obtaining the encoding information supported by the receiving end device, and selecting a high-quality encoding setting (low Distortion rate, high bit rate) as the current encoding setting.
但是，当采用高音质编码设置对音频文件进行编码时，为了传递同样播放时间量的A2DP音频封包，需要更长的2.4GHz频段空中传输时间。如此一来，在存在2.4GHz频段WiFi信号干扰的情况下将更容易发生音质问题(顿音，杂音，扭曲)。However, when an audio file is encoded with a high-quality encoding setting, longer over-the-air time in the 2.4GHz band is required to deliver the same amount of playback time for A2DP audio packets. In this way, sound quality problems (stutter, noise, distortion) will be more likely to occur in the presence of WiFi signal interference in the 2.4GHz band.

This embodiment relates to a specific method for adjusting the Bluetooth A2DP encoding setting. The execution subject of this embodiment can be a separate device for adjusting the Bluetooth A2DP encoding setting, or a source device integrated with a device for adjusting the Bluetooth A2DP encoding setting. The following uses the execution subject as the source integrated with the device for adjusting the Bluetooth A2DP encoding setting terminal equipment as an example. Please refer to Fig. 2, the method provided in this embodiment may include the following steps:
S101、在AVDTP链路处于初始化状态时或上述AVDTP链路初始化之后发生WiFi模块状态变化事件时，为源端设备确定与上述源端设备的WiFi模块当前的状态参数匹配的编码设置。S101. When the AVDTP link is in the initialization state or when a WiFi module state change event occurs after the AVDTP link is initialized, determine for the source device a coding setting that matches the current state parameters of the WiFi module of the source device.
需要说明的是，源端设备的WiFi模块当前的状态参数能够表征源端设备当前的WiFi干扰程度，本步骤中，在AVDTP链路处于初始化状态时或上述AVDTP链路初始化之后发生WiFi模块状态变化事件时，通过为源端设备确定与上述源端设备的WiFi模块当前的状态参数匹配的编码设置，这样，可保证源端设备的编码设备始终能够适应WiFi干扰程度，以降低WiFi信号对传输数据的干扰。It should be noted that the current state parameters of the WiFi module of the source device can represent the current WiFi interference degree of the source device. In this step, the state of the WiFi module changes when the AVDTP link is in the initialization state or after the above-mentioned AVDTP link initialization When an event occurs, by determining the encoding settings for the source device that match the current state parameters of the WiFi module of the source device, it can be ensured that the encoding device of the source device can always adapt to the degree of WiFi interference, so as to reduce the impact of WiFi signals on the transmitted data. interference.
具体的，AVDTP链路指源端设备和与源端设备连接的接收端设备之间的AVDTP链路。此外，WiFi模块状态变化事件包括WiFi模块打开、WiFi模块关闭、WiFi模块连线2.4GHz路由器、WiFi模块断开2.4GHz断开路由器、WiFi模块开始扫描2.4GHz信道和WiFi模块结束扫描2.4GHz信道。Specifically, the AVDTP link refers to the AVDTP link between the source device and the sink device connected to the source device. In addition, the state change events of the WiFi module include the WiFi module turning on, the WiFi module turning off, the WiFi module connecting to the 2.4GHz router, the WiFi module disconnecting from the 2.4GHz router, the WiFi module starting to scan the 2.4GHz channel, and the WiFi module ending the scanning of the 2.4GHz channel.
本步骤中，在AVDTP链路处于初始化状态时或上述AVDTP链路初始化之后发生WiFi模块状态变化事件时，为源端设备确定与WiFi模块当前的状态参数匹配的编码设置。具体的，可按照如下方法为源端设备确定与WiFi模块当前的状态参数匹配的编码设置，即当WiFi模块当前的状态参数表征源端设备当前的WiFi干扰程度较高时，就从源端设备和接收端设备均支持的编码设置中选择同样源音频时间量需要空中传输时间较短的编码设置作为与WiFi模块当前的状态参数匹配的编码设置。关于为源端设备确定与WiFi模块当前的状态参数匹配的编码设置的具体实现方法和实现原理将在下面的实施例详细介绍，此处不再赘述。In this step, when the AVDTP link is in the initialization state or when the WiFi module state change event occurs after the above-mentioned AVDTP link initialization, determine the encoding setting that matches the current state parameters of the WiFi module for the source device. Specifically, the encoding setting that matches the current status parameters of the WiFi module can be determined for the source device according to the following method, that is, when the current status parameters of the WiFi module indicate that the current WiFi interference degree of the source device is relatively high, the source device Among the encoding settings supported by both the receiving end device and the same source audio time, the encoding setting that requires a shorter air transmission time is selected as the encoding setting that matches the current state parameters of the WiFi module. The specific implementation method and implementation principle of determining the encoding setting that matches the current state parameters of the WiFi module for the source device will be described in detail in the following embodiments, and will not be repeated here.
S102、根据上述AVDTP链路当前的状态，确定上述编码设置的启用策略。S102. According to the current state of the above-mentioned AVDTP link, determine the enabling policy of the above-mentioned encoding setting.
具体的，AVDTP链路的状态包括初始化状态、设置完成未播放状态以及播放状态。此外，源端设备会实时记录AVDTP链路的状态，可从源端设备读取AVDTP链路当前的状态。本步骤中，就根据AVDTP链路当前的状态，确定上述编码设置的启用策略。Specifically, the state of the AVDTP link includes an initialization state, a setting complete and unplayed state, and a playing state. In addition, the source device will record the status of the AVDTP link in real time, and the current status of the AVDTP link can be read from the source device. In this step, according to the current state of the AVDTP link, the enabling policy of the above encoding setting is determined.
可选地，在本申请一可能的实现方式中，本步骤中，若上述AVDTP链路当前的状态为初始化状态或设置完成未播放状态时，确定上述编码设置的启用策略为立即启用；若上述AVDTP链路当前的状态为播放状态时，确定上述编码设置的启用策略为在上述源端设备进入可调整状态时启用。Optionally, in a possible implementation of the present application, in this step, if the current state of the above-mentioned AVDTP link is the initialization state or when the setting is completed and the unplaying state is completed, it is determined that the enable policy of the above-mentioned encoding setting is to enable immediately; if the above-mentioned When the current state of the AVDTP link is the playing state, it is determined that the enabling policy of the above-mentioned encoding settings is enabled when the above-mentioned source device enters the adjustable state.
例如，在AVDTP链路处于初始化状态时，为源端设备确定与WiFi模块当前的状态参数匹配的编码设置后，此时，AVDTP链路处于初始化状态，确定上述编码设置的启用策略为立即启用。再例如，在上述AVDTP链路初始化之后发生WiFi模块状态变化事件时，为源端设备确定与WiFi模块当前的状态参数匹配的编码设置后，此时，若源端设备正在播放音乐，即AVDTP链路处于播放状态，则确定上述编码设置的启用策略为在源端设备进入可调整时机时启用。需要说明的是，当AVDTP链路处于播放状态时，通过将编码设置的启用策略设置为在源端设备进入可调整状态时启用，这样，在源端设备进入可调整状态时再启用上述编码设置，可降低对用户的影响，实现无接缝切换。For example, when the AVDTP link is in the initialization state, after determining the encoding settings that match the current state parameters of the WiFi module for the source device, at this time, the AVDTP link is in the initialization state, and the enabling strategy for determining the above encoding settings is to enable immediately. For another example, when the WiFi module state change event occurs after the above-mentioned AVDTP link initialization, after determining the encoding setting that matches the current state parameters of the WiFi module for the source device, at this time, if the source device is playing music, that is, the AVDTP link If the channel is in the playing state, it is determined that the enabling policy of the above encoding settings is enabled when the source device enters an adjustable timing. It should be noted that when the AVDTP link is in the playback state, by setting the enable policy of the encoding setting to enable when the source device enters the adjustable state, in this way, enable the above encoding settings when the source device enters the adjustable state , which can reduce the impact on users and realize seamless switching.
具体的，可调整状态包括曲目切换状态或播放暂停状态。具体实现时，源端设备需要监听从AVRCP应用的两个事件：EVENT_TRACK_CHANGED(曲目切换事件)和EVENT_PLAYBACK_STATUS_CHANGED(播放中到暂停的参数切换事件)，当监听到这两个事件时，表征源端设备进入可调整状态。Specifically, the adjustable state includes a song switching state or a playback pause state. During specific implementation, the source device needs to monitor two events from the AVRCP application: EVENT_TRACK_CHANGED (track switching event) and EVENT_PLAYBACK_STATUS_CHANGED (parameter switching event from playback to pause), when these two events are monitored, it indicates that the source device has entered Adjustable state.
S103、采用上述启用策略启用上述编码设置，并在上述编码设置启用时，将上述编码设置发送给与上述源端设备连接的接收端设备。S103. Use the enabling policy to enable the encoding setting, and when the encoding setting is enabled, send the encoding setting to the receiving end device connected to the source end device.
具体的，当经过步骤S101和步骤S102确定了与WiFi模块当前的状态参数匹配的编码设置以及该编码设置的启用策略时，本步骤中，就采用上述启用策略启用上述编码设置，并在上述编码设置启用时，将上述编码设置发送给与上述源端设备连接的接收端设备。例如，当启用策略为立即启用时，此时，就立即启用上述编码设置，并将上述编码设置发送给接收端设备，以使接收端设备根据接收到的编码设置重新配置本端的编码设置。Specifically, when the encoding setting that matches the current state parameters of the WiFi module and the enabling policy of the encoding setting are determined through steps S101 and S102, in this step, the above-mentioned enabling policy is used to enable the above-mentioned encoding setting, and in the above-mentioned encoding When the setting is enabled, the above encoding settings will be sent to the sink device connected to the above source device. For example, when the enabling policy is enabled immediately, at this time, the above-mentioned encoding settings are immediately enabled, and the above-mentioned encoding settings are sent to the receiving end device, so that the receiving end device reconfigures the encoding settings of the local end according to the received encoding settings.
再例如，当启用策略为在源端设备进入可调整状态时启用，此时，结合上面的描述，则在源端设备监听到曲目切换事件或播放中到暂停的参数切换事件时(当源端设备监听到上述事件时，表征源端设备进入可调整状态)，启用上述编码设置，并将上述编码设置发送给接收端设备。需要说明的是，此时，在源端设备将上述编码设置发送给接收端设备之前，源端设备会先将上述AVDTP链路的状态调整为设置完成未播放状态，然后将上述编码设置发送给接收设备，之后再将上述AVDTP链路的状态调整为播放状态，进而使用重新设置的编码设置播放音乐。For another example, when the enabling policy is enabled when the source device enters an adjustable state, at this time, combined with the above description, when the source device detects a track switching event or a parameter switching event from playing to pause (when the source device When the device detects the above events, it means that the source device enters an adjustable state), enables the above encoding settings, and sends the above encoding settings to the receiving end device. It should be noted that at this time, before the source device sends the above encoding settings to the receiving end device, the source device will first adjust the status of the above AVDTP link to the state of setting completed and not playing, and then send the above encoding settings to The receiving device then adjusts the status of the above-mentioned AVDTP link to the playback status, and then uses the reset encoding settings to play music.
本实施例提供的方法，在AVDTP链路处于初始化状态时或上述AVDTP链路初始化之后发生WiFi模块状态变化事件时，通过为源端设备确定与源端设备的WiFi模块当前的状态参数匹配的编码设置，并根据AVDTP链路当前的状态，确定上述编码设置的启用策略，进而采用上述启用策略启用上述编码设置，并在上述编码设置启用时，将上述编码设置发送给与所述源端设备连接的接收端设备。这样，可保证源端设备的编码设备始终能够适应WiFi干扰程度，以降低WiFi信号对传输数据的干扰，避免在存在WiFi干扰时因编码设置不当造成的音质问题。此外，通过确定编码设置的启用策略，进而采用确定出的启用策略启用编码设置，可实现无接缝调节，以降低因调节编码设置对使用者造成的影响。In the method provided by this embodiment, when the AVDTP link is in the initialization state or when a WiFi module state change event occurs after the above-mentioned AVDTP link initialization, by determining for the source device the code that matches the current state parameters of the WiFi module of the source device setting, and according to the current state of the AVDTP link, determine the enabling policy of the above-mentioned encoding settings, and then use the above-mentioned enabling policy to enable the above-mentioned encoding settings, and when the above-mentioned encoding settings are enabled, send the above-mentioned encoding settings to the receiving device. In this way, it can ensure that the encoding device of the source device can always adapt to the degree of WiFi interference, so as to reduce the interference of the WiFi signal on the transmitted data, and avoid sound quality problems caused by improper encoding settings when there is WiFi interference. In addition, by determining the enabling policy of the encoding setting, and then using the determined enabling policy to enable the encoding setting, seamless adjustment can be realized, so as to reduce the impact on the user caused by adjusting the encoding setting.
图3为本申请调节蓝牙A2DP编码设置的方法实施例二的流程图。本实施例涉及的是为源端设备确定与WiFi模块当前的状态参数匹配的编码设置的具体过程。请参照图3，在上述实施例的基础上，本实施例提供的方法，步骤S101具体包括：FIG. 3 is a flow chart of Embodiment 2 of the method for adjusting Bluetooth A2DP encoding settings in the present application. This embodiment relates to the specific process of determining the encoding settings that match the current state parameters of the WiFi module for the source device. Please refer to FIG. 3, on the basis of the above-mentioned embodiments, the method provided in this embodiment, step S101 specifically includes:
S201、确定与上述源端设备的WiFi模块当前的状态参数对应的干扰程度值。S201. Determine an interference degree value corresponding to a current state parameter of the WiFi module of the source device.
具体的，源端设备的WiFi模块的状态参数包括：WiFi模块的开关状态、WiFi模块的连线状态、WiFi模块的天线状态和WiFi模块的默认码率。本步骤中，可根据上述源端设备的WiFi模块当前的状态参数以及不同的状态参数与不同的干扰程度值的对应关系，确定与上述源端设备的WiFi模块当前的状态参数对应的干扰程度值。需要说明的是，与上述源端设备的WiFi模块当前的状态参数对应的干扰程度值＝WiFi模块的开关状态对应的干扰程度值*WiFi模块的天线状态对应的干扰程度值*(WiFi模块的连线状态对应的干扰程度值+WiFi模块的默认码率对应的干扰程度值)。例如，在本申请一可能的实现方式中，不同的状态参数与不同的干扰程度值的对应关系如表1所示：Specifically, the state parameters of the WiFi module of the source device include: the switch state of the WiFi module, the connection state of the WiFi module, the antenna state of the WiFi module, and the default code rate of the WiFi module. In this step, the interference degree value corresponding to the current state parameter of the WiFi module of the above-mentioned source-end device can be determined according to the current state parameters of the WiFi module of the above-mentioned source-end device and the corresponding relationship between different state parameters and different interference degree values . It should be noted that the interference degree value corresponding to the current state parameter of the WiFi module of the above-mentioned source device=the interference degree value corresponding to the switch state of the WiFi module*the interference degree value corresponding to the antenna state of the WiFi module*(connection of the WiFi module The interference degree value corresponding to the online state + the interference degree value corresponding to the default code rate of the WiFi module). For example, in a possible implementation of the present application, the corresponding relationship between different state parameters and different interference degree values is shown in Table 1:
表1不同的状态参数与不同的干扰程度值的对应关系Table 1 Correspondence between different state parameters and different interference degree values
下面给出一个具体的例子，用以详细介绍本步骤的具体实现过程。例如，在本申请一可能的实现方式中，源端设备的WiFi模块当前的状态参数如表2所示，此时，根据表1，确定WiFi模块的开关状态对应的干扰程度值为1、WiFi模块的天线状态对应的干扰程度值为1、WiFi模块的连线状态对应的干扰程度值为4、WiFi模块的默认码率对应的干扰程度值为2，进一步地，与上述源端设备的WiFi模块当前的状态参数对应的干扰程度值＝WiFi模块的开关状态对应的干扰程度值*WiFi模块的天线状态对应的干扰程度值*(WiFi模块的连线状态对应的干扰程度值+WiFi模块的默认码率对应的干扰程度值)，这样，确定与上述源端设备的WiFi模块当前的状态参数对应的干扰程度值等于6。需要说明的是，根据表1可知，当源端设备的WiFi模块的状态参数发生变化时，与上述源端设备的WiFi模块当前的状态参数对应的干扰程度值在0到16之间变化。A specific example is given below to introduce the specific implementation process of this step in detail. For example, in a possible implementation of the present application, the current state parameters of the WiFi module of the source device are shown in Table 2. At this time, according to Table 1, determine that the interference degree value corresponding to the switch state of the WiFi module is 1, WiFi The interference degree value corresponding to the antenna state of the module is 1, the interference degree value corresponding to the connection state of the WiFi module is 4, and the interference degree value corresponding to the default code rate of the WiFi module is 2. The interference degree value corresponding to the current state parameter of the module = the interference degree value corresponding to the switch state of the WiFi module * the interference degree value corresponding to the antenna state of the WiFi module * (the interference degree value corresponding to the connection state of the WiFi module + the default value of the WiFi module In this way, it is determined that the interference degree value corresponding to the current state parameter of the WiFi module of the source device is equal to 6. It should be noted that, according to Table 1, when the state parameter of the WiFi module of the source device changes, the interference degree value corresponding to the current state parameter of the WiFi module of the source device changes between 0 and 16.
表2源端设备的WiFi模块当前的状态参数Table 2 Current state parameters of the WiFi module of the source device
S202、若上述干扰程度值小于或者等于第一预设阈值，则确定上述源端设备当前的第一编码格式为与上述WiFi模块当前的状态参数匹配的编码格式、以及从上述源端设备和上述接收端设备均支持的上述第一编码格式对应的编码参数中选择与上述干扰程度值对应的编码参数，并确定选择的编码参数为与上述WiFi模块当前的状态参数匹配的编码参数。S202.

If the source device and the receiver device do not support APT-X HD, then determine that APT-X is an encoding parameter that matches the current state parameter of the WiFi module (for example, in one embodiment, both the source device and the receiver support The encoding parameters corresponding to the APT-X encoding format are APT-X HD, APT-X, and APT low delay. At this time, it is determined that APT-X HD is an encoding parameter that matches the current state parameters of the WiFi module).
