Multiple description video coding using adaptive temporal sub-sampling

Abstract

Multiple description coding (MDC) is a promising alternative for robust transmission of information over non-prioritized and unpredictable networks. Especially, MDC has emerged as an attractive approach for video applications where retransmission is unacceptable or infeasible. In this paper, an effective MD video codec is designed based on pre- and post-processing of video sequences, without any modification to the source or channel codec. Considering different motion information of inter-frame, adaptive temporal sub-sampling is employed to the original video data. As a result, adaptive redundancy can make a better tradeoff between the reconstruction quality and compression efficiency. The experimental results exhibit better performance of the proposed scheme than other schemes. © 2007 IEEE.
