Abstract
Wyner-Ziv and wavelet video coding is described. In one aspect, Wyner-Ziv frames from multiple frames of source video content are zero-tree entropy encoded to generate encoded Wyner-Ziv content. The zero-tree entropy encoding operations are based on high-order statistical correlations among wavelet transforms from the Wyner-Ziv frames. The encoded Wyner-Ziv content is communicated to a decoder for decoding to generate reconstructed Wyner-Ziv frames for presentation to a user.
