Abstract

An image processing and display system employs a high speed image LAN (31) for transferring image data separate from control data. A general purpose LAN (21) carries graphics data and control data of the system. One more image display controller (25) than display monitor (23) is used to provide off-line processing of images prior to display of the images. An analog cross-bar switch (45) povides the necessary connections between image display controllers (25) and the display monitors (23) to provide the desired views of selected images. Images are initially provided to the system from an image archive in a compressed manner. The images are decompressed and held in a local cache (35). With respect to each word of image data, different bytes of the word are compressed by different compression schemes to optimize transfer time of image data. A method is employed for transparently sharing a high performance image archive processor among various workstations of display monitors (23).
