Abstract :
Low bandwidth makes real-time video over wireless and mobile networks expensive and limits transmission length. An architecture that substitutes a person´s face with a text-based facial vector description transmitted over a network in tandem with a voice stream requires minimal bandwidth, enabling real-time videophony over various wireless networks
