Abstract
A system for decoding variable length coded DVC data and methods of operating the same result in a variable length decoder engine that receives video frames having a plurality of digital interchange format (DIF) sequences and provides contiguous decoded run-length amp pairs. The variable length decode engine comprises a concatenation engine configured to contiguously format a plurality of DIF blocks of a DIF sequence to provide contiguous DCT blocks. The concatenation engine has a controller that utilizes several passes capable of running simultaneously to return the DIF blocks coded according to IEC standards to their original variable length sequences. A run-length amp pair generator coupled to the concatenation engine configured to decode the contiguous DCT blocks to provide the run-length amp pairs.
