Abstract:

Distributed video coding（DVC）is a new compression paradigm based on Slepian ＆ Wolf and Wyner ＆ Ziv theorems.Compared with traditional video coding standard,its typical characteristics make it be a very comparable solution scheme to encode and to transmit video signal for wireless application.This paper provides the analysis of its key technologies,reviews the advances of fundamental building blocks of distributed video coding,and points out its key problems in future development.

Key words: video compression, distributed video coding, Wyner-Ziv coding, key frame, side information
