Abstract:  This paper describes a novel approach towards achieving efficient transfer of video disparity data, i.e. data conveying depth information of a video scene, over a constant bit-rate ATM channel. Disparity data are produced from the processing of video data from two or more video cameras and are used in conjunction with the video bit-streams to generate intermediate views on an autostereoscopic monitor. Errors in the coded disparity bit-stream cause large synthesis errors in the recreated image even when the lossy algorithms are configured for high quality mode. Thus a lossless compression algorithm has to be used for compressing the disparity information. In our approach, we use a simple but robust method of controlling the output bit-rate of the lossless compression algorithm while reducing the degradation of the recreated autostereoscopic scene. This method minimizes the number of rejected frames and spreads the introduced ‘noise’ so that it remains visually undetected.
