摘要
In this paper, a new error-resilient video coding method with scene adaptation is proposed, which is based on video redundancy coding (VRC) of H.263 Version 2, formerly known as H.263+. The proposed error-resilient mechanism adaptively changes the VRC coding parameters for multiple threads according to the channel status. Also, the scene-adaptation is incorporated into the network-aware error resilient method in order to reduce the motion-jerkiness occurred by an abrupt scene change. Simulation results show that the proposed adaptive VRC mechanism does not only react properly to the time-varying network status, but also reduce fluctuations of the video quality.
