摘要
A system for converting a heterogeneous compressed moving picture data, includes: a variable length decoder for generating variable length decoded data as first compressed moving picture data from a first data bit stream; a compressed moving picture data analyzer for analyzing layer types of the first compressed moving picture data; a layer-matching device for matching layers of the first compressed moving picture data to layers of second compressed moving picture data, thereby generating the second compressed moving picture data; and a variable length encoder for generating variable length coded data as a second data bit stream. Thereby, the system can convert an H.261 compressed moving picture data to an MPEG-1 compressed moving picture data on a compression domain.
