In this paper we consider two separate applications of Wyner-Ziv coding of motion video. The Wyner-Ziv Theorem on source coding with side information available only at the decoder suggests that an asymmetric video codec, where indi- vidual frames are encoded separately but decoded conditionally (given temporally adjacent frames) could achieve efficiency comparable to current interframe video compression systems. We report first results on a Wyner-Ziv coding scheme for motion video that uses intraframe encoding, but interframe decoding. Secondly, we apply Wyner-Ziv coding to the transmission of compressed video over an errorprone channel. We use Wyner-Ziv Coding to generate a supplementary bitstream which contains a coarsely quantized representation of the transmitted video signal
