Error Resiliency of Distributed Video Codingin Wireless Video Communication

摘要

Distributed Video Coding (DVC) is a new paradigm in video coding, based on the Slepian-Wolf and Wyner-Zivtheorems. DVC offers a number of potential advantages: flexible partitioning of the complexity between theencoder and decoder, robustness to channel errors due to intrinsic joint source-channel coding, codec independentscalability, and multi-view coding without communications between the cameras. In this paper, we evaluate theperformance of DVC in an error-prone wireless communication environment. We also present a hybrid spatialand temporal error concealment approach for DVC. Finally, we perform a comparison with a state-of-the-artAVC/H.264 video coding scheme in the presence of transmission errors.
