在当前帧间视频压缩系统中，编码器执行预测编码以利用连续帧的相似性。关于具有仅在解码器处可用的边信息的源编码的Wyner-Ziv定理表明，其中单独帧被单独编码但有条件地解码（给定时间相邻帧）的非对称视频编解码器可以实现类似的效率。我们报告的第一个结果的Wyner-Ziv编码方案的运动视频，使用帧内编码，但帧间解码。
In current interframe video compression systems, the encoder performs predictive coding to exploit the similarities of successive frames. The Wyner-Ziv theorem on source coding with side information available only at the decoder suggests that an asymmetric video codec, where individual frames are encoded separately, but decoded conditionally (given temporally adjacent frames) could achieve similar efficiency. We report the first results on a Wyner-Ziv coding scheme for motion video that uses intraframe encoding, but interframe decoding.
