An Implementation of the Media Processing Unit for Multimedia Communication Terminal

In this paper, we propose the new architecture of the media processing unit of set top unit(STU) and show the result of its implementation in ETRI video on demand(VOD) system, IMPRESS (Interactive Multimedia exPRESS). The STU in our system has MPEG-2 video quality in movie on demand but low quality in bi-directional communication in consideration of implementation cost. The media processing unit in our STU consists of three parts. One is system control module which has RISC processor and it controls overall functions of the unit, another is MPEG-2 decoder module which decodes MPEG-2 transport stream(TS) in real time and presents the contents, and the third is audio/video communication module which enables bidirectional video conferencing each other.
