A selective intra-coding approach for multiple description video coding
Multiple Description Coding (MDC) is a technique for video transmission over error prone networks where the descriptions are routed over multiple paths. Intra coding technique and MDC both provides error resiliency for realtime video transport over unreliable networks. In this paper, we present our investigation results for a new intra coding approach for MDC where selective frames are fully encoded in intra mode instead of coding selective macroblocks in intra mode in many frames. We implemented our scheme in the H.264/AVC reference software, JM16.0. Based on the experimental performance evaluation, we show that our method achieves higher average PSNR compared to the other optimized MDC schemes available in the literature.
