Abstract
The role of computer-to-computer communication has become essential in today's society. Establishment of two-way image communication, between remote locations, has until recently suffered from the high bandwidth requirement associated with visual data. Over the past several years, scientists at the Communications Research Centre have been developing a bandwidth reduction coding scheme for the transmission of image data over various communication media. A two node network for interactive image communication, operating over 300 baud switched telephone lines, has been demonstrated at CRC in Ottawa. The system is based on the concept of a common visual space, wherein an identical image is presented to both users. The image may be modified by either participant, the results of which will be seen by both. TRUNCATED
