ABSTRACT:
Embodiments herein provide a method and apparatus for recognition and tagging of multiple layered entropy coding system. The method comprises receiving a signal and performing entropy average coding to produce an entropy coded bit stream. Next, the method adds a tag to a beginning portion of the entropy coded bit stream. The tag comprises a plurality of headers, wherein each of the headers differs from one another, and wherein the headers comprise an elongated bit stream. Following this, the method reads the tag when processing the entropy coded bit stream and avoids subsequent entropy averaging on the entropy coded bit stream when the tag is present. The avoiding of the subsequent entropy averaging avoids unnecessary coding and entropy averaging of the entropy coded bit stream.
