METHOD AND SYSTEM FOR MONITORING VIDEO WITH SINGLE PATH OF VIDEO AND MULTIPLE PATHS OF AUDIO

摘要

The present invention provides a method and system for monitoring video with single channel of video and multiple channels of audio. The method comprises: allocating a fixed initial SSRC value for each channel of audio by a device end; establishing an RTSP interaction mode between a client end and the device end; the client end requesting, from the device end, 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 modifying the initial SSRC value in the RTP packet of each channel of audio to the corresponding modified SSRC value, then sending the RTP packet of each channel of audio containing 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 user's demands. The present invention fulfills to audio-video capturing of multiple channels of audio and single channel of video and enables a user to select freely a video and/or audio of a corresponding channel to play.
