Transmission of a much clearer content with more images over a network with a limited band is in strong demand. The existing moving picture coding technology, however, is inadequate to respond to such needs, although expectations for the next generation moving picture coding technology with higher compression rates is increasing. The summary of the MPEG4-AVC/H.264, which is the latest international standard for the coding of moving pictures, is introduced in this paper, followed by the introduction of the technical features of the high-quality MPEG4-AVC/H.264 CODEC of Oki Electric.
