An encoder based rate smoothing scheme which uses explicit slicebased mode selection has been proposed recently. The algorithm provides significantly smoother bitstream from a variable bit rate (VBR) encoder and reduces the network queuing delay while maintaining quality for the end-user. In this paper we investigate the error robustness of the proposed scheme based on H.264/AVC codec. The results show that, the proposed scheme maintains error resilience properties without extra delay. Compared to the standard frame based scheme, the algorithm provides almost the same average distortion while reducing the distortion variance which helps improving the subjective video quality. We investigate the performance in random and bursty packet loss environments, and it shows that the proposed scheme is applicable for error prone networks, for example, wireless networks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
