Abstract :
We present an error resilient video coder compatible with the ITU-T H.263 standard. Resynchronization flag insertion, error detection, localization and concealment in the decoder, and dynamic programming mode selection based on error tracking are the three main adopted error-resilient strategies. An information feedback method, which utilizes the H.263 video bit stream but does not modify its syntax, is described. Simulation results for the binary symmetric channel (BSC) with random bit errors are given to show the robustness of the proposed video coder
