Abstract

A run-level domain transcoder (134) receives a stream of compressed frames (136) carried in a bit stream. The run-level domain transcoder decodes the bit stream into run-level pairs and selectively processes the compressed frames so as to, among other things, reduce the number of bits necessary to represent the compressed frames.
