| Popis: | 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. |
