We have developed a real-time MPEG2 (simple profile at main level) encoder chip set with ENC-M for motion compensation and ENC-C for coding/control. This set has full functions and sufficient processing power for real-time compression of NTSC 4:2:0 video signals (720 x 480 pels, 30 frames/s), with only three external memories: 4-Mbit VRAM, 16-Mbit synchronous DRAM, and 2-Mbit FIFO-structured DRAM. These features enable us to implement, for example, a small PC board for NTSC video CODEC.
