Abstract
A parallel decoder for an MPEG-2 encoded video signal includes a deformatter which separates the input bit stream into multiple portions, each representing a respectively different section of the HDTV image. The separate portions are processed in parallel by respective decoders. In order to perform motion compensated processing, each of the four decoders includes a memory that holds data representing the entire image. Each decoder provides its decoded output data to all of the decoders to maintain the data in the respective memories.
