Low data rate video communications

It is pointed out that progress in technology is resulting in a greater coverage of digital data communication systems, as well as vast increases in the processing power of integrated circuits, particularly for video and data processing. The author describes the methods of motion video communication over integrated services digital networks and other low-data-rate links resulting from these advances in technology. Three main areas are covered: video conferencing, video telephony, and video surveillance. The different criteria for these areas are described, together with solution techniques and implementations. Associated topics, such as world standards and additional features and facilities, are also discussed
