Abstract

The present invention relates generally to a system and method of managing a Push To Talk (PTT) conversation while the recipient is watching television. PTT messages may be conveyed by an initiator to a recipient through the use of a telephone connected to a network. The network is also connected to either a set top box (STB) or a Digital Video Recorder (DVR). Within the network resides a presence state machine, which determines if a PTT conversation may be initiated. Upon initiation of a PTT conversation the presence state machine may pause the television by a command to the STB or DVR. If the television has been paused, upon termination of the PTT conversation, the presence state machine instructs the STB or DVR to resume television display.

Claims

1. A presence state module for enabling a push to talk (PTT) communication between an initiator and a recipient of said PTT communication, comprising:

a first module operatively connected to a set top box or a digital video recorder, wherein said first module is configured to collect recipient presence data;

a data storage medium operatively connected to said first module, wherein said data storage medium is configured to store received presence data from said first module, wherein said presence data identifies a current television program being displayed, and wherein said presence data further identifies a first television program designated to be interrupted for said PTT communication and a second television program designated to not to be interrupted for said PTT communication; and

a second module operatively connected to said data storage medium, wherein said second module is configured to filter said PTT communication to said recipient based on said presence data, wherein said PTT communication is allowed to interrupt said current television program when said first television program is being broadcast, and wherein said PTT communication is not allowed to interrupt said current television program when said second television program is being broadcast.

2. The presence state module of claim 1 wherein said current television program is interrupted by pausing said current television program.

3. The presence state module of claim 2 wherein said current television program is recorded during said PTT communication.

4. The presence state module of claim 1 wherein said first television program comprises television commercials, and wherein said second television program comprises said current television program.

5. The presence state module of claim 1 wherein said presence data further identifies either or both of a whitelist or a blacklist to aid in determining whether a request for said PTT communication will be allowed to interrupt said current television program depending if the initiator is on the whitelist or the blacklist.

18. The presence state module of claim 1 wherein said presence data further identifies hours of a day that said PTT communication may or may not interrupt said current television program.

6. An apparatus, comprising:

means for collecting recipient presence data through a module operatively connected to a set top box or a digital video recorder, wherein said presence data identifies a current television program being displayed, and wherein said presence data further identifies a list of television programs during which said current television program may not be interrupted for a push to talk (PTT) communication;

means for storing said presence data on a computer readable medium, wherein said medium is operatively connected to said module;

means for filtering PTT communication requests based, at least in part, on said stored presence data;

means for displaying a filtered PTT request when said current television program is not included in said list of television programs; and

means for automatically refusing said PTT communication when said current television program is included in said list of television programs.

7. The apparatus of claim 6 wherein said PTT communication is automatically accepted when a television commercial is being displayed during said current television program.

8. The apparatus of claim 6 wherein said PTT communication is automatically accepted when said current television program is not included in said list of television programs, and wherein said current television program is temporarily interrupted during said PTT communication.

19. The apparatus of claim 6 wherein said presence data further identifies channels and hours of a day that said PTT communication may or may not interrupt said current television program.

9. A method comprising:

receiving presence data identifying a current television program being displayed, wherein said presence data further identifies a list of television programs designated as not to be interrupted by a push to talk (PTT)communication;

storing said presence data on a computer readable medium;

receiving a PTT;

filtering said PTT request based, at least in part, on said presence data;

establishing said PTT communication based on said filtered PTT request when said current television program is not included in said list of television programs, wherein said current television program is temporarily interrupted during said PTT communication; and

automatically rejecting said PTT communication based on said filtered PTT request when said current television program is included in said list of television programs.

10. The method of claim 9 wherein temporarily interrupting said current television program comprises pausing said current television program.

11. The method of claim 9 wherein said PTT communication is only allowed to interrupt said current television program during a commercial break.

12. The method of claim 9 wherein said presence data further identifies a blacklist to aid in determining whether said current television program is to be interrupted, and wherein said PTT communication, when associated with a PTT initiator included in said blacklist, is automatically rejected.

20. The method of claim 9 wherein said presence data further identifies hours of a day and days in a week that said PTT communication may or may not interrupt said current television program.

13. A computer-readable medium having instructions stored thereon, wherein execution of said instructions by at least one device causes said at least one device to:

receive presence data, wherein said presence data indicates a current television program being displayed, and wherein said presence data further indicates a list of television programs that may not be interrupted for a push to talk (PTT) communication;

store said presence data;

receive a PTT request from an initiator;

filter said PTT request based, at least in part, on said presence data;

establish said PTT communication in response to said filtered PTT request when said current television program is not included in said list of television programs, wherein said current television program is temporarily interrupted during said PTT communication; and

automatically reject said PTT communication when said current television program is included in said list of television programs.

14. The computer-readable medium according to claim 13 wherein said presence data further indicates a preference to have the current television program paused during said PTT communication.

15. The computer-readable medium according to claim 13 wherein said presence data further identifies a group of current viewers of said current television program.

16. The computer-readable medium according to claim 15 wherein PTT communications from one or more of said group of current viewers are allowed to interrupt said current television program.

17. The computer-readable medium according to claim 13 wherein said PTT communication is automatically established when said PTT request is received during a commercial break of said current television program.
