Abstract

This paper presents an improved motion compensated version of the Visual Pattern Image Sequence Coding (VPISC) paradigm. It is a high performance video codec that is easily implemented in software. Software video codecs are not only cheaper, but are more flexible system solutions because they enable multi-vendor computers to exchange encoded video information without requiring on-board protocol compatible video codec hardware. The codec is intended for real-time desktop computer applications like multimedia delivery, and local area network (as well as point-to-point) televideo conferencing. We describe a version of motion compensated VPISC (MCVPISC) that has achieved bit rates of 0.025 bpp or better for MPEG test sequences (source coding has further reduced the bit rate by about half). The computational complexity of the encoder is less than 3 integer operations per pixel. The decoder is bounded between 0.016 and 0.125 logical and integer operations per pixel.
