Video compression makes big gains

How new standards for video compression and new IC chips will change the worlds of computing, broadcasting, and communication is discussed. An explanation of how video compression works is given. The three digital video standards that have been proposed are described. They are the Joint Photographic Experts Group (JPEG) standard for still picture compression, the Consultative Committee on International Telephony and Telegraphy (CCITT) Recommendation H.261 for video teleconferencing, and the Moving Pictures Experts Group (MPEG) for full-motion compression on digital storage media. Some available chip sets are described, and the issue of design flexibility is considered.<
