Changing bandwidth usage based on user events
First Claim
1. A method comprising:
- sending from a network interface a stream of an active video conference to a video terminal;
receiving at the network interface a first message from the video terminal, wherein the first message was generated based on a user of the video terminal changing a focus of the user;
changing in a codec, the stream of the active video conference based on the first message; and
sending from the network interface, the changed stream of the active video conference to the video terminal.

Abstract
Once an active video conference is set up and a user is viewing the active video conference at a video terminal, the video terminal looks for different events that indicate a change in focus of the user to or from the active video conference. For example, the user brings up another application and starts using the application or the user has minimized a window that is displaying the active video conference. The video terminal sends a change of focus message based on the event to a video conference bridge or another video terminal that is streaming the active video conference to the user. The video conference bridge/video terminal processes the message and changes video portion of the stream of the active video conference based on the message. The result is that there is improved use of bandwidth between the video terminal and the video conference bridge/video terminal.
