Abstract

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
