A video data receiving system for a videophone, which is characterized in that the system comprises a video pre-decoding module, a key frame request module and a video receiving module; wherein,
一种可视电话的视频数据接收系统，其特征在于，该系统包括：视频预解码模块、关键帧请求模块和视频接收模块；其中，
Through the structure of the video data receiving system for the videophone, the video pre-decoding module is utilized to pre-decode each frame of the received video data and judge whether the video data is damaged, the key frame request module is utilized to discard the damaged offset frame data in the video data and send a key frame request signal to the videophone at the opposite terminal when the number of the continuously discarded offset frame data reaches a preset value; then the video receiving module is utilized to receive the key frame data generated by the videophone at the opposite terminal by coding the current video transmission data according to the key frame request signal.
通过本发明所述可视电话的视频数据接收系统的上述结构，利用视频预解码模块对所接收的每一帧视频数据进行预解码，判断每一帧视频数据的关键数据是否损坏，利用关键帧请求模块根据视频预解码模块的预解码结果，丢弃视频数据中损坏的偏移帧数据，并统计连续丢弃的偏移帧数据的数目，当连续丢弃的所述偏移帧数据的数目达到一预设数值时，向对端可视电话发送关键帧请求信号；之后通过视频接收模块接收对端可视电话根据所述关键帧请求信号对当前视频传输数据进行编码生成的关键帧数据。
Step S205: the key frame request module of the first videophone obtains the analysis result of the video analysis module and the judgment result of the video pre-decoding module, and directly transmits the frame of video image data into the video decoding module of the first videophone for playing when the pre-decoding result of the frame of video image data is normal data, or although being error data, the frame of video image data is I frame data; discards the frame of video image data and counts the number of error frames of P frame data when the frame of video image data is P frame data and the pre-decoding result is error data, and sends a key frame request signal to the second videophone according to the H. protocol standard if the number of continuous error frames reaches 3.
步骤S205：第一可视电话的关键帧请求模块获取视频分析模块的分析结果以及视频预解码模块的判断结果，当该帧视频图像数据的预解码结果为正常数据或者虽然为出错数据，但数据类型为I帧数据时，则直将该帧视频图像数据转入第一可视电话的视频解码模块进行解码之后播放；当该帧视频图像数据为P帧数据，且预解码结果为出错数据时，则丢弃该帧视频图像数据，同时累计P帧数据的出错帧数，若连续出错帧数达到3帧时，则根据H.协议标准向第二可视电话发送关键帧请求信号。
Step S204: the video pre-decoding module of the first videophone pre-decodese the frame of video image data, and analyzes the key information of the video data according to the syntax and the semanteme drawn up in the H. protocol standard to judge whether the frame of video image data is damaged.
步骤S204：第一可视电话的视频预解码模块对该帧视频图像数据进行预解码，根据H.协议标准设定的句法和语义分析该帧视频图像数据的关键信息，判断该帧视频图像数据是否损坏。
After the video pre-decoding module pre-decodes the received video data, the method also comprises the following steps
