Abstract	This paper discusses the current state of compression for digital video on the desktop. Today there are many choices for video compression that yield different performance in terms of compression factor, quality, bitrate, and cost. Users want a single low cost solution which, unfortunately, today is non-existent. Consequently, users will have to develop applications in an environment with multiple representations for digital video unless PC's can be assigned to dedicated applications. Alternatively, programmable compression/decompression boards can be used to solve the problem. Eventually, special-purpose hardware solutions will be replaced by general-purpose software running on desktop parallel processors which will be implemented by multiple CPU's per chip. 1.1 Introduction This paper presents my opinion of the current state of the art for compression for desktop digital video applications. Put simply, there are too many compression algorithms and standards and too few low-cost boards that implement the major standards. 1.2 Current State of the Art There are numerous video compression algorithms including: Apple's Roadpizza, Supermac's CINEPACK, Fractals, H.261, Intel's INDEO, motion JPEG (MJPEG), MPEG-1, MPEG-2, Sun's CELLB, and Wavelets. Users are confused by all these 2 1 Video Compression for Desktop Applications choices. They want to know which technology to use so they can make intelligent investment decisions. Unfortunately, the current situation is not very good because there is no single technology that can be used for all applications. For example, Apple's Roadpizza and Supermac's CINEPACK are designed for playback applications with softwareonly decoding, H.261 is designed for video teleconferencing, MPEG-1 is designed for low bitrate (e.g., 1.5Mbs) audio ...
