Paper Abstract

The challenge of providing a robust six megahertz video data channel for remotely piloted vehicles (RPV's) has caused several old standby techniques to be reviewed. Spread spectrum methods, the most promising class for robust channel signalling, require source bandwidths much smaller than those of the channel. Consequently, the application of video data compression algorithms to limit source bandwidths play an important role. Several video data compression techniques that have been applied to the RPV problem to date are discussed, ranging from direct pictorial redundancy reduction, to reduction of frame rate, to data synthesis. These illustrate how special requirements of the RPV video problem are addressed in the designs. This paper describes the general scenario in which the RPV video capability will be used. Major techniques discussed will include transform coding on subpictures, hybrid coding, slow frame rate data processing and source content adaptive variable resolution data processing. The RPV video communications system truly provides a new challenge to the video data compression community.
