Open publisher page 1 citations

Abstract

The quality of real-time video in network monitoring system can be easily affected by network bandwidth.This paper introduced a Closed-Loop rate control strategy based on RTCP.This strategy analyzes the feedback of the receiver report(RR) in RTCP,adjusts the bit rate of encoding,adaptive network carrying capacity.This paper also proposed a stream traffic shaping policy to solve the problem of the data burst of H.264 stream by inhibiting data burst,thus avoiding sudden transient network congestion and reducing packet loss.Experimental results show that the strategy effectively reduces the transmission stream packet loss rate and improves the quality of real-time video.
