Abstract :
Research on high-capacity mobile communications is approaching modems capable of transmitting 64 kb/s in a 30-kHz channel. This rate has made it possible to conceive of new mobile services, the most ambitious of which is perhaps video. Although data rates of 64 kb/s are thought of as very high in the mobile environment, this is a very low rate for video. Many techniques for implementing video at rates between 64 and 128 kb/s have focused on teleconferencing or videophone over a high-quality channel. The results of the investigation into how to adapt the p×64 video coding standard so that it will be suitable for the coding of QCIF formal (176×144) video sequences for mobile transmission are presented. It is concluded that the codec design presented should be robust enough to allow reasonable quality video transmission over a mobile channel operating at 64 kb/s
