We developed a low-power, low-cost, single-chip MPEG2 (half-D1) video codec LSI for portable consumer-products applications. We achieved this by limiting the functions, reducing the maximum processing image size, adopting an efficient search range for motion estimation, and supporting a field offset sub-sampling method. This LSI can encode and decode at 27 MHz with a power consumption of 0.5 W at 1.8 V
