Abstract
In recent years numerous standards such as H.261 [1], MPEG-1 [2], and MPEG-2 [3] have been introduced to address the compression of video data for digital storage and communication services. Together, the applications for these standards span the gamut from low bit-rate video telephony to high quality HDTV with a new emerging standard, H.263 [4], targeting the low bit-rate end. More specifically, the primary mission for H.263 is traditionally regarded as the coding of digital video at rates suitable for transmission over public switched telephone network (PSTN) lines. Fast modems suited for this application typically run at 28.8 Kbits per second (Kb/s) within which video, audio, data, and overhead must be transmitted. This places a demanding rate constraint on the video coder which in most cases must operate at less than 24 Kb/s. In terms of wireless mobile networks whose capacities are often less than 19.2 Kb/s [5], this range of operation is also very conducive. Not surprisingly then, in addition to traditional telephony, there has been a significant and growing interest in the extension of the H.263 standard to mobile and wireless applications [6].
