Abstract
In a videoconference images are not always displayed across the entirety of a viewing endpoint's screen. For example, a user may wish to view more than one videoconference participant at a time. Providing images of more than one participant can result in large amounts of bandwidth being required to transmit the data for all the images from the endpoints to the Multi-Conference Unit and maintain the resolution for all the images. Therefore, the present invention provides a method for reducing the data sent by an endpoint in response to flow control messages sent by the MCU in response to a change in the size at which the endpoint's image is being viewed.
