Multicast Video Transport overiPOINT ATM Testbed

Abstract

In addition to the development of Video Server and Video Client applications, we have designed and implemented a novel ATM Network Video Interface Module. This module receives ATM cells from an ATM switch port, performs all the re-assembly functions and extracts video data from the adaptation layer frames. This module also detects any lost data in the video stream and sends a repair request to the Video Server. We have used an X86 embedded controller with an ISA interface, an ISA backplane, a FIFO module on an ISA board for developing this network module. The embedded controller feeds video data (MPEG-2) to a hardware decoder board. The decoder board provides NTSC output such that full-motion decoded MPEG-2 video can be viewed on an NTSC terminal.
