Abstract: A video monitoring scheme of video was proposed under a heterogeneous network, which included a network condition evaluation method and a video coding method under network with adjustable parameters. Firstly, a model of the video monitoring system for the south-to-north water diversion project under heterogeneous network was proposed. Secondly, a network parameters evaluating method based on the real-time transport protocol/real-time transport control protocol (RTP/RTCP) was presented to improve video coding efficiency with adjustable parameters. Finally, the performance of the video monitoring scheme was proved by the system deployed in the middle route of south-to-north water diversion project. The performance of the video coding in current bandwidth and the video transmission efficiency were improved under heterogeneous network. The video monitoring system met the design requirements of four channel 720P video monitoring. -
