Abstract

A macro-block level parallel video decoder for a parallel processing environment is provided. The video decoder includes a Variable Length Decoding (VLD) block for decoding the encoded Discrete Cosine Transform (DCT) coefficients, a master node that receives the decoded DCT coefficients, and multiple slave nodes/processors for parallel implementation of Inverse Discrete Cosine Transform (IDCT) and motion compensation at the macro-block level. Also provided is a method for macro-block level video decoding in a parallel processing system.
