Test Conditions and Error Concealment for SVC Based on RTP Encapsulation
Wei Liu, Yongsheng Liang, Xu Chen, Jihong Zhang · 2010
Real-time Transport Protocol (RTP) is usually used to provide real time transportation and quality guarantee of scalable video coding (SVC) stream. Base on the analysis of SVC stream structure and real-time transport protocol, RTP encapsulation is implemented for H.264/SVC stream. A simulation method is proposed to simulate the transport process of the scalable video in the common test conditions by isolating the base layer and enhancement layers. Error concealment based on RTP encapsulation is proposed to improve the video quality, and it solve the problem that enhancement layer may be lost. Simulation test shows the effectiveness, compatibility and extendibility of the RTP encapsulation mechanism.
