Method and system for providing continuous presence video in a cascading conference
First Claim
1. A cascading continuous presence composition controller (CCCC) adapted to manage the composition of a cascading continuous presence stream in a video conference involving a plurality of multipoint control units (MCUs), each MCU associated with a plurality of endpoints, wherein the CCCC is configured to:
- communicate with each of the plurality of MCUs;
select one or more endpoints to be included in the cascading continuous presence stream, independently of which MCU is associated with which endpoint;
instruct a first MCU to compose an associated continuous presence video stream that comprises video streams from the selected endpoints associated with the first MCU and send the associated continuous presence video stream to a second MCU; and
instruct the second MCU to compose the cascading continuous presence stream comprising video streams received from the selected endpoints associated with the second MCU and the video streams comprised in the associated continuous presence video stream received from the first MCU.

Abstract
Disclosed herein are methods and systems for providing continuous presence video stream in a cascading video conference, i.e., a video conference that is conducted over more than one MCU. A cascading continuous presence composition controller (CCCC) selects which endpoints from among all of the endpoints participating in the conference should be displayed in the layout, regardless of which endpoints are associated with which MCU. The CCCC can be resident on one of the MCUs, resident on a cascading conference server, or can be distributed among all of the MCUs involved in a cascading conference.
