Method and system for monitoring video with single path of video and multiple paths of audio
The present invention provides a method and system for video surveillance with a single channel of video and multiple channels of audio. The method comprises: a device end allocating a fixed initial SSRC value for each channel of audio; a client end and the device end establishing an RTSP interaction mode; the client end requesting, from the device end, a single channel of video and multiple channels of audio, the device end randomly generating, for each channel of audio, a corresponding modified SSRC value, and sending the same to the client end; the device end capturing the single channel of video and the multiple channels of audio and sending an RTP packet of the single channel of video to the client end, and after modifying the initial SSRC value in the RTP packet of each channel of audio to the corresponding modified SSRC value, sending the RTP packet of each channel of audio including the modified SSRC value to the client end; the client end distinguishing individual channels of audio according to the modified SSRC values in the RTP packets of the multiple channels of audio, and playing the video and/or the audio of a corresponding channel according to a user's demand. The present invention can implement audio-video capturing of multiple channels of audio and a single channel of video, and enable a user to select freely and play video and/or audio of a corresponding channel.
