Abstract
This paper discusses video compression and decompression strategies for use on general purpose computer systems where no specialized hardware is available. We first examine the alternatives and describe the performance and limitations of the first generation of such methods. A brief description is given of the possible algorithmic approaches. We introduce requirements for the encoder/decoder, and show that a vector quantization based scheme with image preprocessing and classification can provide the required performance. The remainder of the paper deals with the algorithm design and the tradeoffs made to meet the goals of realtime decode capability, compression ratio and image quality. Finally, we present results for the optimized algorithm and indicate areas which appear to be most promising for further work.
