A multimedia system is an integrated computing environment that acquires different formats of data, integrates them while maintaining their relationships, manipulates them, and presents them selectively upon user commands. It should be powerful enough to handle various operations involving text, image, video, audio, and graphics data. We have developed one such system, the MediaStation 5000 (UWGSP5), a highly-integrated desktop multimedia system on a single PC plug-in board. It can perform multistandard compression, high-speed image processing, and fast 2-D & 3-D graphics functions. The processing power and the programmability is provided by the Texas Instruments Multimedia Video Processor (MVP), a single-chip multiprocessing device with a highly parallel internal architecture. The MediaStation 5000 is capable of performing real-time MPEG-1 video and audio encoding at SIF resolution, 30 frames per second. It is a highly integrated audio, video, image and graphics processing system which transforms a standard VL-Bus PC into a real-time multimedia supercomputer.
Precision Digital Images has licensed the right to use MediaStation 5000 technology in their line of image processing products.
