Abstract
A system and method for communication of information using channels of different latency combine a high latency communication channel with a low latency communication channel to reduce the communication delay perceived by a user. The system and method includes separating information into first and second components based on a parameter correlated to the perceived delay, communicating the first component via a first channel, communicating the second component via a second channel having a communication delay greater than the first channel, and generating a representation of the information based on the first component. The second component of the information may be used to augment or modify the information represented by the first component. In one embodiment, the invention is applied to video teleconferencing where voice information and basis image information is transmitted via the low latency channel while background and other non-real-time information is communicated via the high latency communication channel.
