Abstract
A dial-up aural and visual communication system includes a telecommunication network with a switch connected thereto, a codec subsystem connected to the switch and video equipment connected to the switch via the codec subsystem with voice communication equipment connected directly to the switch. The codec subsystem is shared between several end users and can be located near the switch. Sharing the codec reduces cost and amount of equipment at end users desk. The codec subsystem can also switch video, including composite video, between local lines and can include frame and image storage. The codec can transmit at 9.6 kbps, p.times.64 kbps, and via ISDN. The system can be used for video conferencing, remote surveillance or desk-top services, and can include an image grooming system. Images may be stored in switch facilities traditionally used for voice mail.
