Abstract

A parallel-pipeline video signal processing system is disclosed which includes a statistical decoder, an arithmetic and logic unit and a pixel interpolator which operate in parallel under the control of sequencing circuitry to expand a compressed video signal. The video signal may have been developed using a variety of compression techniques including Huffman-type statistical encoding.
