Abstract
A method and apparatus for providing multiple interactive video teleconferencing sessions over a standard ISDN line is described. Multiple sets of audio, video, and data information are generated and transmitted to a bandwidth allocation device which determines what portion of that information will be transmitted over the ISDN line. Additionally, priority request values are generated that assist the bandwidth allocation device in performing its allocation function such that users interacting with the audio, video and data generation sources will experience acceptable levels of interaction even when bandwidth demand is greater than the supply.
