Motion-compensated oversampled filterbanks for robust video coding

During the past years, many efforts are devoted for efficient coding of video. However, this high coding efficiency results in an increased sensitivity to transmission errors. This is the motivation for developing techniques allowing altogether to transmit video sequences efficiently and to be robust to the transmission errors. This paper proposes a joint source-channel coding scheme using motion-compensated oversampled filterbanks (OFBs). Previous work for robust transmission using OFBs have concentrated on still images. Here, OFBs are combined with motion compensation techniques. The redundancy introduced by the overcomplete representation is employed for error correction of the motion compensated frames. Experimentations have shown that performances are acceptable even when the compressed stream is transmitted through a binary symmetric channel with crossover probability of 10(-2).
