| Abstract: | In this paper, we propose an embedded video terminal that supports MPEG-4 and fits in with multimedia teaching system. The terminal is based on JADE Z228, which is a typical system-on-chip （Soc） processor. With the hardware and software design introduced, the terminal is able to decode MPEG-4 bit stream up to 30 frames per second at VGA resolution （640x480）. The Z228-based terminal boasts its high performanceto-cost ratio, featuring in the whole complex MPEG-4 decoder implemented by oniy a single chip. |
