Video Compression for Desktop Applications

1 Video Compression for Desktop Applications Lawrence A. Rowe

University of California, Berkeley, CA, USA

This paper discusses the current state of compression for digital video on the desk-top. Today there are many choices for video compression that yield different perfor-mance 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 representa-tions for digital video unless PC’s can be assigned to dedicated applications. Alter-natively, 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
