A New Feedback Control Strategy of Video Transmission Based on RTP
Lihong Xu, Shuhua Ai · 2006
The paper sources from a project of embedded video monitor system based on MPEG_4. The system uses RTP for real-time service and uses RTCP for QoS service. First the paper discusses the basic principle of RTP/RTCP, and then puts forward a new feedback control strategy based on RTP protocol. The strategy makes the system adjust the code rate and stream size dynamic and adjust itself to network state. The strategy offsets the disadvantages of TCP and UDP, which is very useful for video monitor
