초록
Scalable video coding (SVC) is currently being developed as an extension to the H.264/AVC by the Joint Video Team (JVT). The SVC addresses coding schemes for reliable video delivery over heterogenous network for diverse clients using available system resources. SVC error resilience strives for reliability as well as efficiency of video transmission under unreliable network conditions. This paper presents a polyphase downsampling based redundant picture coding for SVC error resilience. Simulation results report that the proposed method outperforms the SVC error concealment method by 1.7 dB on average in terms of the PSNR. ©2008 IEEE.
