This letter presents a real‐time lossless compression/decompression unit for disparity map information used in 3D teleconferencing systems. A lossless compression algorithm is used to compress the disparity map data in real‐time, resulting in a variable bit‐rate data stream that has to be transmitted through a constant bit‐rate channel. The system uses a controlled‐data‐loss method for data rate adaptation and for minimizing the loss of information.
