Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

What is claimed is :

1. A method of synchronizing a client with a media signal, the method comprising:
receiving one or more actions corresponding to the media signal;
determining an application for handling at least one of the one or more received actions; and
causing the determined application to handle at least one of the one or more received actions.

2. The method of claim 1, wherein the media signal
comprises at least one of the following: an audio signal and a video signal.

3. The method of claim 1, wherein determining an
application comprises parsing action information.

4. The method of claim 3, wherein parsing action
information comprises determining if the action information corresponds to a URI (Universal Resource Indicator) .

5. The method of claim 3, wherein parsing action
information comprises determining if the action information corresponds to a command.

6. The method of claim 1, wherein causing the determined application to handle at least one of the actions comprises causing an Internet browser to navigate to a URI specified in the action.

7. The method of claim 1, further comprising prompting a user before causing the determined application to handle the action.

8. The method of claim 1, further comprising queuing the action.

9. The method of claim 1, wherein the action comprises at least one of the following: a URI and an application command.

10. The method of claim 9, wherein the action comprises an indication of when the determined application should handle the action.

11. The method of claim 10, wherein the indication
comprises a SMPTE (Society of Motion Pictures and Television Engineers) time-code.

12. The method of claim 1, wherein receiving the at least one actions comprises receiving the at least one actions from a server.

13. The method of claim 1, further comprising
receiving criteria associated with the action; and
evaluating the criteria.

14. The method of claim 13, wherein the criteria comprises one or more user characteristics.

15. The method of claim 14, wherein the user
characteristics comprises at least one of the following: age, location, and gender.

16. A computer program product, disposed on a computer readable medium, the computer program for synchronizing a client with a media signal, the program comprising instructions for causing a processor to: receive one or more actions corresponding to the media signal;
determine an application for handling at least one of the one or more received actions; and
cause the determined application to handle at least one of the one or more received actions.

18. A method of synchronizing one or more clients with a media signal, the method comprising:
receiving information identifying an action corresponding to the media signal;
receiving information identifying criteria for the action; transmitting the action and criteria toward the one or more clients.

19. The method of claim 18, wherein the action comprises identification of a time for processing the action and at least one of the following: a URI and an application command.

20. The method of claim 18, wherein transmitting the action and criteria toward one or more clients comprises
transmitting the action and criteria to a server.

21. The method of claim 20, further comprising determining at the server, based on the action criteria, whether to transmit the action to a client.

22. The method of claim 21, wherein determining comprises determining based on user characteristics associated with the client.

23. The method of claim 22, wherein the user
characteristics comprise one or more of the following: age, gender, and location.

24. The method of claim 18, further comprising
receiving the action and criteria at a client; and
determining at the client, based on the action criteria, whether to execute the action.

25. The method of claim 24, wherein determining comprises determining based on user characteristics.

26. The method of claim 25, wherein the user
characteristics comprise one or more of the following: age, gender, and location.

27. A method of synchronizing a client with a media signal, the method comprising:
receiving one or more actions corresponding to the media signal, the actions including an indication of a time to execute each action;
determining a delay time for the action; and
handling the action in accordance with the delay time.

28. The method of claim 27, wherein determining a delay time comprises determining a delay time based on the location of a client.

29. The method of claim 27, wherein determining a delay time comprises determining a delay time based on a broadcast medium used to transmit the media signal to a household of the client .

30. The method of claim 27, wherein handling the action comprises determining when to transmit the action from a server to the client .

31. The method of claim 27, wherein handling the action comprises determining when to execute the action at the client.
