摘要

本文介绍了一种将预编码的MPEG-2比特流按视觉重要性递减的顺序划分为任意数量的分区的有效技术。对于固定的分区大小比率，这可以通过在一个或一组宏块内交错的VLC代码来实现。该算法能够重新创建一个语法正确的比特流，而不考虑次要分区上的错误率，这使得它适用于许多高效的传输方案。

Efficient partitioning of coded video bitstreams for multi-channel wireless transmission

This paper introduces an efficient technique for dividing a pre-coded MPEG-2 bitstream into an arbitrary number of partitions, in decreasing order of visual importance. For a fixed partition size ratio, this has been achieved by VLC code interleaving within a macroblock or group of macroblocks. The algorithm is capable of recreating a syntactically correct bitstream, regardless of the error rate on secondary partitions, making it applicable to many efficient transmission schemes.
