Abstract:

Wyner-Ziv (WZ) video coding -a particular case of distributed video coding (DVC) -is a new video coding paradigm based on two major Information Theory results: the Slepian-Wolf and Wyner-Ziv theorems. Many of the practical WZ video coding solutions available in the literature make use of a feedback channel (FC) to perform rate control at the decoder which implies there must be a FC available in the application scenario addressed. The FC-based DVC solutions also have implications in terms of delay and decoder complexity since several iterative decoding operations may be needed to decode the data to the target quality level. In this context, this paper proposes an encoder rate control (ERC) solution for the transform domain WZ coding architecture previously using a FC driven rate control. Although this is the first solution in the literature, promising results are achieved with the proposed ERC solution without significantly increase the encoder complexity.
