| 摘 要： | When video signals are transmitted over noisy chan-nels such as wireless networks, there will be errors inthe transmitted bit stream. Traditional coding methodsmake video more sensitive to channel errors because ofspatial and temporal propagation due to using variablelength codes (VLC) and motion compensation, respec-tively. Error detection and concealment are extremelyimportant components of error robust video codec. Theprocess of error detection can be divided into two steps.First, video b…
