Abstract
A video system that captures telephone number data encoded into video signals transmitted over a video network to at least one display device is disclosed. Video signals are received that contain an escape sequence demarcating telephone number data. The system identifies the escape sequence, and captures the telephone number data. Upon command, dialing data corresponding to the telephone number data are transmitted over a telephone network to initiate a telephone call to the desired party.
