XMOVIE - ARCHITECTURE AND IMPLEMENTATION OF A DISTRIBUTED MOVIE SYSTEM

We describe a system for storing, transmitting, and presenting digital movies in a computer network. The hardware used in the system is stan dard hardware, as found in typical workstations today; no special hard ware is required, but if available it can be used to provide better pe rformance. The XMovie system has several innovative features. First, i t Contains a new algorithm for the gradual adaptation of the color loo kup table during the presentation of the movie to ensure optimal color quality on low-end workstations. Second, it is a multistandard system supporting the compression techniques MPEG, Motion JPEG, and a newly developed extension to the well-known Color Cell Compression method. T hird, it contains AdFEC, a new adaptable forward error correction meth od for our movie transmission protocol.
