摘要

研究了一种MPEG2数字视频压缩方案的误差控制。压缩视频通过异步传输模式(ATM)网络传输。我们提出将错误控制编码与错误隐藏相结合。具体来说，我们使用经典的错误检测来定位压缩域中的错误，将这些信息转换到未压缩域中，然后在错误位置使用标准错误隐藏。用这种方法解决误差定位问题是本工作的主要贡献。

Combined error detection and error concealment for MPEG2 over ATM

We study error control for an MPEG2 digital video compression scheme. The compressed video is transmitted over an asynchronous transfer mode (ATM) network. We propose to combine error control coding with error concealment. Specifically we use classical error detection to locate errors in the compressed domain, translate this information to the uncompressed domain and then use standard error concealment in the error locations. The solving of the error location problem in this way is the main contribution of this work.
