摘要

In distributed video coding, individual frames are encoded independently but decoded conditionally. The Wyner-Ziv theorem-based source coding with side information only available at the decoder states that an intraframe encoder with interframe decoder system can approach the efficiency of a conventional interframe encoder and decoder system. In this paper, a new block discrete cosine transform (DCT)-based Wyner-Ziv video codec with coding mode-aided motion compensation at the decoder is proposed. The key is that for each block, a large amount of candidate blocks are evaluated based on some criteria derived from Reed-Solomon (RS) decoding and best neighborhood matching to find the best candidate block as the side information. Another characteristic is that error correction code (ECC) decoding is proposed to participate in generating side information. Compared with some known Wyner-Ziv video coding systems, in the proposed video codec, no extra information should be transmitted and feedback channel is unnecessary. The coding performance of our method has been verified through simulations.
