1. A method for composing a videoconferencing displayed image, comprising:
- creating a description of a videoconferencing displayed image;
providing the description to an endpoint;
providing one or more video streams to the endpoint; and
composing at the endpoint based on the description the videoconferencing displayed image from the one or more video streams,wherein the description comprises location and size information corresponding to each of the one or more video streams.

Abstract
The present disclosure provides methods and systems of multipoint videoconferencing wherein layout description information is used to create videoconferencing displayed images of a composite video of one or more video images and one or more accessory elements. The layout description information is responsive to events in the videoconferencing session. Synchronization between the images of the composite video and the one or more accessory elements is done by using synchronization information that reflects the event.

11. A videoconferencing apparatus, comprising:
-
a logic module adapted to create one or more endpoint layout description files corresponding to events in a videoconference, wherein the one or more endpoint layout description files, when processed at an endpoint, create from one or more received video streams a videoconferencing displayed image to be presented at the endpoint; and a network interface adapted to send the one or more endpoint layout description files to the endpoint. - View Dependent Claims (12, 13, 14, 15, 16)
