Abstract
Abstract Improved apparatus and method for encoding and decoding information is disclosed herein. The invention uses the same marker segment information to engage an encoder or a decoder. The technique eliminates many of the complexities associated with building parameter lists, and generating various types of marker segments in a form compatible with both the decode and encode processing.
