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, by a central processing unit (CPU), an auxiliary output port;

determining, by the CPU, that the end-point is in a video projection mode by;

detecting that the end-point has been configured for projection by an internal video projection function;

determining that the end-point is in the video projection mode because the end-point has been configured for projection;

reporting, by the CPU, independently of an instant message, a video projection status that the end-point is in the video projection mode to one or more messaging system clients, the video projection status reported by inserting a privacy element as an extension to a message;

after reporting the video projection status, blocking an instant message sent by a sender; and

notifying the sender that the instant message was blocked.

2. The method of claim 1, wherein determining that the end-point is in a video projection mode comprises:

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

3. The method of claim 1, wherein determining that the end-point is in a video projection mode comprises:

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

4. The method of claim 1, wherein determining that the end-point is in a video projection mode comprises:

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

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

a memory; and

one or more processors configured to;

determine that the end-point is in a video projection mode by;

detecting that the end-point has been configured for projection by an internal video projection function;

determining that the end-point is in the video projection mode because the end-point has been configured for projection;

report, independently of an instant message, a video projecting status that the end-point is in the video projection mode to one or more messaging system clients, the video projection status reported by inserting a privacy element as an extension to a message;

after reporting the video projection status, block an instant message sent by a sender; and

notify the sender that the instant message was blocked.

6. The apparatus of claim 5, the one or more processors configured to:

report the video projecting status through a network interface component.

7. The apparatus of claim 5, the one or more processors configured to:

report the video projecting status as a privacy element in a Presence Information Data Format message.

8. The apparatus of claim 5, the one or more processors configured to:

receive the instant message through a network interface component; and

block the instant message from being displayed through an auxiliary output port.

9. The apparatus of claim 5, wherein the one or more processors determine that the end-point is in a video projection mode by:

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

10. The apparatus of claim 5, wherein the one or more processors determine that the end-point is in a video projection mode by:

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

11. The apparatus of claim 5, wherein the one or more processors determine that the end-point is in a video projection mode by:

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

12. One or more non-transitory computer readable storage media storing software for providing a presence notification to an end-point of a demand-based messaging system, the software comprising code such that when executed is configured to:

monitor an auxiliary output port;

determine that the end-point is in a video projection mode by;

detecting that the end-point has been configured for projection by an internal video projection function;

determining that the end-point is in the video projection mode because the end-point has been configured for projection;

report, independently of an instant message, a video projection status that the end-point is in the video projection mode to one or more messaging system clients, the video projection status reported by inserting a privacy element as an extension to a message;

after reporting the video projection status, block an instant message sent by a sender; and

notify the sender that the instant message was blocked.

13. The computer readable storage media of claim 12, wherein the code is configured to determine that the end-point is in a video projection mode by:

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

14. The computer readable storage media of claim 12, wherein the code is configured to determine that the end-point is in a video projection mode by:

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

15. The computer readable storage media of claim 12, wherein the code is configured to determine that the end-point is in a video projection mode by:

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