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.
Claims25
A method comprising the steps of:
- receiving video signals transmitted over a network;
- identifying an escape sequence signal encoded within the video signals, said escape sequence signal demarcating telephone number data, and said escape sequence signal being perceptually invisible;
- capturing the demarcated telephone number data;
- and
- transmitting the captured telephone number data over a telephone network to initiate a telephone call.
An interactive communication system comprising:
- means for transmitting video signals from at least one central provider to a plurality of video receiving devices, each of said video receiving devices comprising:
- means for receiving said video signals;
- means for capturing telephone number data encoded into said video signals by identifying an escape sequence signal encoded within said video signals demarcating said telephone number data, where said escape sequence signal is perceptually invisible;
- and
- means for transmitting dialing information corresponding to said captured telephone number data over a telephone network to initiate a telephone call.
A video receiving device comprising:
- means for receiving video signals;
- means for capturing telephone number data encoded into said video signals by identifying an escape sequence signal encoded within said video signals demarcating said telephone number data where said escape sequence signal is perceptually invisible, said telephone number data representing more than one telephone number, each telephone number being identified by a separate escape sequence signal;
- and
- means for transmitting DTMF tones corresponding to the telephone number data for a particular telephone number over a telephone network to initiate a telephone call.
