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.

Claims

1. 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.

2. The method of claim 1 wherein said step of capturing said telephone number data comprises the steps of:

storing the captured telephone number data in memory; and

retrieving the captured telephone number data from memory in response to a received access code.

3. The method according to claim 2 wherein the step of storing the captured telephone number data comprises:

storing other data which defines information relating to the telephone number data.

4. The method according to claim 2 further comprising the step of:

indicating the capture of telephone number data.

5. 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.

6. The device of claim 5 wherein said receiving means is a set-top box.

7. The device of claim 5 wherein said capturing means can be selectively enabled and disabled.

8. The device of claim 5 further comprising means for indicating the capture of telephone number data.

9. The device according to claim 8 wherein said indicating means is an LED indicator.

10. The device of claim 6 further comprising means for storing said captured telephone number data.

11. The device according to claim 5 wherein said telephone number data includes other data which defines information relating to the telephone number data.

12. 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.

13. The device of claim 12 wherein said receiving means is a television.

14. The device of claim 12 wherein said receiving means is a computer.

15. The device of claim 12 wherein said capturing means can be selectively enabled and disabled.

16. The device of claim 12 wherein said receiving means includes a set-top box.

17. The device of claim 12 wherein said capturing means comprises storing means for storing said telephone number data.

18. The device of claim 17 further comprising

means for assembling a history log of said stored telephone number data,

means for displaying said history log;

and

means for selecting telephone number data from said history log which represents a particular telephone number.

19. The device of claim 12 further comprising means for indicating the capture of telephone number data.

20. The device of claim 19 wherein said indicating means is an LED indicator.

21. The device of claim 12 wherein said telephone number data includes other data which defines information relating to the telephone number data.

22. A method comprising the steps of:

receiving video signals transmitted over a network;

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 a plurality of telephone numbers, said telephone number data representing each telephone number being identified by a separate escape sequence signal; and

transmitting DTMF tones corresponding to said captured telephone number data for a particular telephone number over a telephone network to initiate a telephone call.

23. The method according to claim 22 wherein said step of capturing the telephone number data comprises the steps of:

storing the captured telephone number data in memory; and

retrieving the captured telephone number data from memory in response to a received access code.

24. The method according to claim 23 wherein said step of storing said captured telephone number data comprises the step of:

assembling a history log of the telephone numbers represented by the telephone number data stored in memory.

25. The method according to claim 24 further comprising the steps of:

displaying said history log;

initiating the dialing of a particular telephone number in response to a selection of the particular telephone number from the history log.
