本申请一些实施例中，输入源信号还包括：图像数据在预监画面中的目标位置，在第二目标分辨率对应的预监画面上，展示第一目标分辨率对应的图像数据，可以为在预监画面的目标位置处，展示第一目标分辨率对应的图像数据，其中，目标位置与图像数据一一对应，例如，第1路输入源信号对应的图像数据为A，且该图像数据在预监画面中的位置为左上，则在预监画面的左上位置展示图像数据A，需要说明的是，上述图像数据包括但不限于：视频以及图片。In some embodiments of the present application, the input source signal also includes: the target position of the image data in the preview screen, and the image data corresponding to the first target resolution is displayed on the preview screen corresponding to the second target resolution, which can be At the target position of the preview screen, the image data corresponding to the first target resolution is displayed, wherein the target position corresponds to the image data one by one, for example, the image data corresponding to the first input source signal is A, and the image data If the position in the preview screen is the upper left, the image data A is displayed on the upper left position of the preview screen. It should be noted that the above image data includes but not limited to: video and pictures.
本申请一些实施例中，在基于多个第一目标分辨率和路数确定多个图像数据进行拼接后得到的预监画面的第二目标分辨率之后，可以接收目标对象的第一操作指令，选中预监画面中的至少一张第一目标图像数据，然后可接收目标对象的第二操作指令，需要说明的是，该第二操作指令用于指示将第一目标图像数据按照预定比例进行扩大或者缩小，根据第二操作指令，将第一目标分辨率对应的第一目标图像数据按照预定比例进行扩大或者缩小。例如，用户甲需要将预监画面中B图像中的视频数据进行重点查看，则可接收用户甲的第一操作指令，选中B图像，然后将该B图像放大预定比例进行查看，可以理解的，由于在扩大或者缩小第一目标图像的过程中，不改变该第一目标图像数据的分辨率，因此，并不会对预监画面的整体分辨率造成影响，因此，无需调整除了目标对象所选中的第一目标图像数据以外的其他图像数据的分辨率大小。In some embodiments of the present application, after determining the second target resolution of the preview screen obtained by splicing multiple image data based on the multiple first target resolutions and the number of channels, the first operation instruction of the target object may be received, Select at least one piece of first target image data in the preview screen, and then receive a second operation instruction of the target object. It should be noted that the second operation instruction is used to instruct to enlarge the first target image data according to a predetermined ratio Or shrinking, according to the second operation instruction, the first target image data corresponding to the first target resolution is enlarged or reduced according to a predetermined ratio. For example, if user A needs to focus on viewing the video data in image B in the preview screen, he can receive the first operation instruction from user A, select image B, and then enlarge the image B to a predetermined ratio for viewing. It is understandable that Since the resolution of the first target image data is not changed during the process of enlarging or reducing the first target image, it will not affect the overall resolution of the preview screen, so there is no need to adjust The resolution size of image data other than the first target image data.
本申请一些可选的实施例中，在基于多个第一目标分辨率和路数确定多个图像数据进行拼接后得到的预监画面的第二目标分辨率之后，可以接收目标对象的第三操作指令，选中预监画面中的至少一张第二目标图像数据，接收目标对象的第四操作指令，设置第二目标画面的第五图像分辨率，需要说明的是，第五图像分辨率大于第一目标分辨率，以用于在预监画面展示第五图像分辨率对应的第二目标图像数据，可以理解的，在预监画面分辨率大小一定的情况下，图像数据的分辨率越大，则图像画面对应的清晰度越大，人体肉眼观察到的图像越清晰、越细腻，例如，用户乙需要查看预监画面中的C图像数据的某些细节，则可接收用户乙的第三操作指令，选中该第三操作指令对应的C图像数据，并接收用户乙的第四操作指令，需要说明的是，该第四操作指令用于设置C图像数据的第五图像分辨率大小，将C图像数据当前的分辨率大小，调整为用户乙设置的第七分辨率大小，并对C图像数据进行展示，以便于用户乙查看C图像数据的某些图像细节。In some optional embodiments of the present application, after determining the second target resolution of the preview screen obtained after splicing multiple image data based on the multiple first target resolutions and the number of channels, the third resolution of the target object may be received. Operation instruction, select at least one piece of second target image data in the preview screen, receive the fourth operation instruction of the target object, and set the fifth image resolution of the second target image. It should be noted that the fifth image resolution is greater than The first target resolution is used to display the second target image data corresponding to the fifth image resolution on the preview screen. It can be understood that when the resolution of the preview screen is fixed, the resolution of the image data is larger , the higher the corresponding definition of the image screen is, the clearer and more delicate the image observed by the naked eye of the human body is. An operation instruction, select the C image data corresponding to the third operation instruction, and receive a fourth operation instruction from user B. It should be noted that the fourth operation instruction is used to set the fifth image resolution of the C image data, and set The current resolution of the C image data is adjusted to the seventh resolution set by the user B, and the C image data is displayed so that the user B can view certain image details of the C image data.
可以理解的，在预监画面展示第五图像分辨率对应的第二目标图像数据之前，可以调整预监画面中，除了第二目标图像数据以外的其他图像数据的第一目标分辨率，使得预监画面的第二目标分辨率保持不变，即，为了保证C图像数据的高清晰度，可以暂时降低其他图像数据的分辨率。It can be understood that before the second target image data corresponding to the fifth image resolution is displayed on the preview screen, the first target resolution of other image data other than the second target image data in the preview screen can be adjusted, so that the preview The second target resolution of the monitoring screen remains unchanged, that is, in order to ensure the high definition of the C image data, the resolution of other image data may be temporarily reduced.
容易注意到的是，由于对图像进行扩大或者缩小不会影响图像的分辨率，因此为了将某张图像的数据更加观察的更加清晰，可以先将图像的分辨率提高，然后，在将该图像进行放大。It is easy to notice that since expanding or reducing the image will not affect the resolution of the image, in order to observe the data of a certain image more clearly, you can first increase the resolution of the image, and then, in the image to zoom in.

该系统中，输入卡01，用于采集多路输入源信号，根据采集到的输入源信号的路数，确定第一目标分辨率，并按照第一目标分辨率对多路输入源信号对应的图像数据进行压缩，得到多个图像数据，其中，输入源信号包括：待显示图像数据的信息，输入源信号与图像数据一一对应；辅助卡02，用于基于多个第一目标分辨率和路数确定多个图像数据进行拼接后得到的预监画面的第二目标分辨率；多画面预监卡03，用于向目标编码芯片发送第二目标分辨率对应的预监画面，以用于在第二目标分辨率对应的预监画面上，展示第一目标分辨率对应的图像数据，达到了基于输入的输入源路数动态调整输入源信号对应的图像的分辨率以及各个输入源信号拼接形成的预监画面的分辨率的目的，从而避免了直接将大量输入源信号在编码芯片进行处理，实现了预监画面可以较为流畅清晰显示的技术效果，进而解决了由于相关技术在编码芯片对大量输入源信号进行数据处理造成的编码芯片处理数据压力过大，进而导致预监画面卡顿，画质下降的技术问题。In this system, the input card 01 is used to collect multi-channel input source signals, determine the first target resolution according to the number of channels of the collected input source signals, and determine the corresponding multi-channel input source signals according to the first target resolution. The image data is compressed to obtain a plurality of image data, wherein the input source signal includes: the information of the image data to be displayed, and the input source signal corresponds to the image data one by one; the auxiliary card 02 is used to The number of ways determines the second target resolution of the preview screen obtained after splicing multiple image data; the multi-screen preview card 03 is used to send the preview screen corresponding to the second target resolution to the target encoding chip for use in On the preview screen corresponding to the second target resolution, the image data corresponding to the first target resolution is displayed, and the resolution of the image corresponding to the input source signal can be dynamically adjusted based on the number of input source channels and the splicing of each input source signal can be achieved. The purpose of the resolution of the preview screen formed is to avoid directly processing a large number of input source signals in the encoding chip, and realize the technical effect that the preview screen can be displayed more smoothly and clearly, and then solve the problem caused by related technologies in the encoding chip. The data processing of a large number of input source signals causes the encoding chip to process data too much pressure, which leads to technical problems such as the freeze of the preview screen and the decline of image quality.
需要说明的是，第一目标分辨率包括：第一图像分辨率与第二图像分辨率，需要说明的是，第一图像分辨率大于第二图像分辨率，容易注意到的是，根据采集到的输入源信号的路数，确定图像数据压缩后对应的第一目标分辨率，包括：在采集到的输入源信号的路数小于预设阈值的情况下，则确定图像数据压缩后的第一目标分辨率为第一图像分辨率；在采集到的输入源信号的路数大于预设阈值的情况下，则确定图像数据压缩后的第二目标分辨率为第二图像分辨率，需要说明的是，上述预设阈值可以为接收用户的设置指令人为设置，也可以为系统根据自身运行情况，进行实时调整。It should be noted that the first target resolution includes: the first image resolution and the second image resolution. It should be noted that the first image resolution is greater than the second image resolution. It is easy to notice that according to the collected The number of channels of the input source signal, and determine the corresponding first target resolution after image data compression, including: in the case that the channel number of the collected input source signal is less than the preset threshold value, then determine the first target resolution after image data compression The target resolution is the first image resolution; when the number of input source signals collected is greater than the preset threshold, the second target resolution after image data compression is determined to be the second image resolution, which needs to be explained Yes, the above-mentioned preset thresholds can be set artificially for receiving user setting instructions, or can be adjusted in real time by the system according to its own operating conditions.
本申请一些可选的实施例中，第二目标分辨率包括：第三图像分辨率与第四图像分辨率，其中，第三图像分辨率大于第四图像分辨率，可基于第一目标分辨率确定图像数据拼接形成的预监画面对应的第二目标分辨率，具体地，在确定图像数据压缩后的第一目标分辨率为第一图像分辨率的情况下，则确定预监画面对应的第二目标分辨率为第三图像分辨率；在确定图像数据压缩后的第一目标分辨率为第二图像分辨率的情况下，则确定预监画面对应的第二目标分辨率为第四图像分辨率。In some optional embodiments of the present application, the second target resolution includes: a third image resolution and a fourth image resolution, wherein the third image resolution is greater than the fourth image resolution, and may be based on the first target resolution Determine the second target resolution corresponding to the preview screen formed by image data splicing. Specifically, if the first target resolution after image data compression is determined to be the first image resolution, then determine the second target resolution corresponding to the preview screen. The second target resolution is the third image resolution; in the case of determining that the first target resolution after image data compression is the second image resolution, then determine that the second target resolution corresponding to the preview screen is the fourth image resolution Rate.
图3是本申请一种可选的实施例中输入源预监实现的硬件链路框图，如图3所示，该链路图包括：输入卡01(Input card)，辅助卡02(Aux card，全称Auxiliary card)以及多画面预监卡03(Mvr card，全称Multi-screen-preview)。Fig. 3 is the block diagram of the hardware link that input source preview realizes in a kind of optional embodiment of the present application, as shown in Fig. 3, this link diagram includes: input card 01 (Input card), auxiliary card 02 (Aux card , full name Auxiliary card) and multi-screen preview card 03 (Mvr card, full name Multi-screen-preview).
具体地，每张输入卡支持4路输入源输入，共有30张输入卡，总共120个输入源。在输入预监清晰模式下，每个输入卡可以将4个输入源分别压缩到480x270大小，依次通过每张卡的百兆Eth网(Eth，以太网)链路将压缩后的输入源信息发送到辅助卡，辅助卡可将每个接口的输入源内容在辅助卡的ddr内存中按照顺序拼接成一个4Kx4K的画幅。Specifically, each input card supports 4 input source inputs, and there are 30 input cards in total, with a total of 120 input sources. In the clear mode of input preview, each input card can compress 4 input sources to a size of 480x270, and send the compressed input source information through the 100M Eth network (Eth, Ethernet) link of each card in turn To the auxiliary card, the auxiliary card can sequentially splice the input source content of each interface into a 4Kx4K frame in the ddr memory of the auxiliary card.
然后从ddr内存中读取后通过serdes(高速串行传输链路)传输到多画面预监卡，需要说明的是，受限于serdes的传输速率上限的限制，如果传输4Kx4K大小的画幅，视频帧率只能达到8帧左右，多画面预监卡可将接收到的输入预监画幅通过bt1120视频接口传输给编码芯片，编码芯片将输入预监画幅编码压缩后，可通过千兆网(Giga out)传输到交换机网络。Then read it from the ddr memory and transmit it to the multi-screen preview card through serdes (high-speed serial transmission link). The frame rate can only reach about 8 frames. The multi-screen preview card can transmit the received input preview frame to the encoding chip through the bt1120 video interface. out) to the switch network.
但如果输入源数量比较多，比如达到120个输入源都要进行预监时，海思编码芯片则会收到120个480x270的输入源画面，但受限于其压缩编码的能力，会导致编码后图像质量下降严重且帧率下降较多，画面卡顿严重以及马赛克现象严重。However, if the number of input sources is relatively large, for example, when there are 120 input sources to be previewed, the HiSilicon encoding chip will receive 120 480x270 input source images, but limited by its ability to compress and encode, it will cause encoding Afterwards, the image quality degrades seriously and the frame rate drops a lot, the picture freezes seriously and the mosaic phenomenon is serious.
如果通过切换到输入源流畅模式，即通过输入卡先把每个输入源的预监画面压缩到240x135的大小，再依次传输给辅助卡，辅助卡再将接受到120路输入源预监画面在辅助卡的ddr内存中按照顺序拼接成一个4kx2k的画幅，然后再从其内存中读取后通过serdes传输到多画面预监卡(此时帧率可达到30帧左右)，多画画预监卡再将接受到的输入预监画幅通过bt1120接口传输给海思编码芯片，海思芯片这时的编码压力则会小很多，编码输出的图像效果流畅且无明显马赛克现象。需要说明的是，上述输入卡、辅助卡、多画面预监卡的处理器类型包括但不限于：可编程逻辑阵列FPGA。If you switch to the input source smooth mode, that is, the input card first compresses the preview screen of each input source to a size of 240x135, and then transmits it to the auxiliary card in turn, and the auxiliary card will receive the preview screen of 120 input sources in the The ddr memory of the auxiliary card is spliced into a 4kx2k frame in order, and then read from its memory and transmitted to the multi-screen preview card through serdes (the frame rate can reach about 30 frames at this time), and the multi-drawing preview The card then transmits the received input preview frame to the HiSilicon encoding chip through the bt1120 interface. At this time, the encoding pressure of the HiSilicon chip will be much smaller, and the output image effect of the encoding is smooth without obvious mosaic phenomenon. It should be noted that the types of processors of the above-mentioned input card, auxiliary card, and multi-screen preview card include but are not limited to: programmable logic array FPGA.
可以理解的，在本申请中可以根据需要预监的输入源的多少，动态地进行这两种模式的切换，即输入源较少时采用清晰模式，输入源较多时采用流畅模式，以实现最大程度展现出较好的输入预监效果。It can be understood that in this application, these two modes can be switched dynamically according to the number of input sources that need to be previewed, that is, the clear mode is adopted when there are few input sources, and the smooth mode is adopted when there are many input sources, so as to achieve the maximum The degree shows a better input preview effect.
