Abstract

In accordance with one embodiment of the present invention, a method is provided for communicating a presence notification to an end-point of a demand-based messaging system. The method includes monitoring an auxiliary output port for a video signal; detecting a video signal on the auxiliary output port; and reporting a video projection status to the end-point. In additional or alternative embodiments of the method, the method may include receiving a message from the end-point and blocking the message from being displayed on the auxiliary output port. In yet another additional or alternative embodiment of the method, the method may include sending a message to the end-point indicating that the message has been blocked.

Claims

1. A method for providing a presence notification to an end-point of a demand-based messaging system, the method comprising:

monitoring an auxiliary output port;

determining if the auxiliary output port is configured for video projection; and

reporting a video projection status to the end-point if the auxiliary output port is configured for video projection.

2. The method of claim 1, further comprising:

receiving a message from the end-point; and

blocking the message from being displayed on the auxiliary output port.

3. The method of claim 1, further comprising:

receiving a first message from the end-point;

blocking the message from being displayed on the auxiliary output port; and

sending a second message to the end-point indicating that the first message has been blocked.

4. The method of claim 1, wherein the step of reporting the video projection status comprises:

inserting a privacy element as an extension to a Presence Information Data Format message.

5. The method of claim 1, wherein the step of determining if the auxiliary output port is configured for video projection comprises:

detecting a video signal on the auxiliary output port.

6. The method of claim 1, wherein the step of determining if the auxiliary output port is configured for video projection comprises:

detecting a video signal on the auxiliary output port; and

determining that an internal display is configured to display the same data as the auxiliary output port.

7. The method of claim 1, wherein the step of determining if the auxiliary output port is configured for video projection comprises:

detecting activation of an internal video projecting function that explicitly configures the auxiliary output port for projecting.

8. The method of claim 1, wherein the step of determining if the auxiliary output port is configured for video projection comprises:

detecting activation of an application-level control that configures the auxiliary output port for projecting.

9. An apparatus for providing a presence notification to an end-point of a demand-based messaging system, the apparatus comprising:

a first processing component operable to monitor an auxiliary output port and determine if the auxiliary output port is configured for video projection; and

a second processing component operable to report a video projecting status end-point if the first processing component determines that the auxiliary output port is configured for video projection.

10. The apparatus of claim 9 further comprising:

a third processing component operable to receive a message from the end-point; and

a fourth processing component operable to block the message from being displayed through the auxiliary output port.

11. The apparatus of claim 10 further comprising:

a fifth processing component operable to send a message to the end-point indicating that the message has been blocked.

12. The apparatus of claim 9, further comprising a network interface component;

wherein the second processing component reports the video projecting status through the network interface component.

13. The apparatus of claim 9, wherein the second processing component reports the video projecting status as a privacy element in Presence Information Data Format message.

14. The apparatus of claim 9, further comprising:

a network interface component;

a third processing component operable to receive a message from the end-point through the network interface component; and

a fourth processing component operable to block the message from being displayed through the auxiliary output port.

15. The apparatus of claim 14 further comprising:

a fifth processing component operable to send a message to the end-point through the network interface component indicating that the message has been blocked.

16. The apparatus of claim 9, wherein the first processing component determines if the auxiliary output port is configured for video projection by:

detecting a video signal on the auxiliary output port.

17. The apparatus of claim 9, wherein the first processing component determines if the auxiliary output port is configured for video projection by:

detecting a video signal on the auxiliary output port; and

determining that an internal display is configured to display the same data as the auxiliary output port.

18. The apparatus of claim 9, wherein the first processing component determines if the auxiliary output port is configured for video projection by:

detecting activation of an internal video projecting function that explicitly configures the auxiliary output port for projecting.

19. The apparatus of claim 9, wherein the first processing component determines if the auxiliary output port is configured for video projection by:

detecting activation of an application-level control that configures the auxiliary output port for projecting.

20. Software for providing a presence notification to an end-point of a demand-based messaging system, the software being embodied in a computer readable medium and comprising code such that when executed is operable to:

monitor an auxiliary output port;

determine if the auxiliary output port is configured for video projection; and

report a video projection status to the end-point if the auxiliary output port is configured for video projection.

21. The software of claim 20, wherein the code is further operable to:

receive a message from the end-point; and

block the message from being displayed on the auxiliary output port.

22. The software of claim 21, wherein the code is further operable to:

send a message to the end-point indicating that the message has been blocked.

23. The software of claim 20, wherein the code for determining if the auxiliary port is configured for video projection comprises code such that when executed is operable to:

detect a video signal on the auxiliary output port.

24. The software of claim 20, wherein the code for determining if the auxiliary port is configured for video projection comprises code such that when executed is operable to:

detect a video signal on the auxiliary output port; and

determine that an internal display is configured to display the same data as the auxiliary output port.

25. The software of claim 20, wherein the code for determining if the auxiliary port is configured for video projection comprises code such that when executed is operable to:

detect activation of an internal video projecting function that explicitly configures the auxiliary output port for projecting.

26. The software of claim 20, wherein the code for determining if the auxiliary port is configured for video projection comprises code such that when executed is operable to:

detect activation of an application-level control that configures the auxiliary output port for projecting.

27. Software comprising:

means for monitoring an auxiliary output port;

means fordetermining if the auxiliary output port is configured for video projection; and

means for reporting a video projection status to an end-point of a demand-based messaging system if the auxiliary port is configured for video projection.

28. The software of claim 27 further comprising:

means for receiving a message from the end-point; and

means for blocking the message from being displayed on the auxiliary output port.

29. The software of claim 28 further comprising:

means for sending a message to the end-point indicating that the message has been blocked.
