Using talking heads for real-time virtual videophone in wireless networks
Yang Xiao, Max Garzón, M. Nolen · IEEE Multimedia · 2006
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.
