Video management system over satellite
First Claim
1. A videoconference system comprising:
- a plurality of videoconference terminals each configured to generate a videoconference signal and transmit the videoconference signal on a designated channel amongst a plurality of channels;
a router configured to receive the videoconference signals from each of the plurality of channels;
a control module configured to form a composite videoconference signal having the received videoconference signals, and transmit the composite videoconference signal over a multicast channel different from the plurality of channels, wherein the plurality of videoconference terminals receive the composite videoconference signal and present the videoconference signal; and
a frequency allocation manager configured to receive a communication request from one of the plurality of videoconference terminals, determine availability of the plurality of channels, and assign one of the plurality of channels to the one of the plurality of videoconference terminals on demand based on the determined availability.

Abstract
A videoconference system has videoconference terminals which communicate with a centralized station over satellite. Video signals from each videoconference terminal are unicast to the centralized station via satellite. The centralized station forms a composite signal of all the video signals multicasts the composite signal to the local videoconference terminals over satellite that can be received by hundreds, thousands or more recipients. The system dynamically allocates satellite bandwidth and other network resources to establish a high definition videoconference call on demand. A frequency allocation manager manages the resources available on the satellite network according with the capacity of each transponder and network resources available. It administrates the resources available and dynamically assigns a satellite capacity and network resources.

15. A videoconference system comprising a plurality of videoconference terminals each configured to generate a videoconference signal and transmit the videoconference signal on a designated channel amongst a plurality of channels via satellite to a centralized server which forms a composite videoconference signal having the received videoconference signals from each of the plurality of videoconference terminals, each of said plurality of videoconference terminals further configured to receive via satellite a composite videoconference signal on a multicast channel different from the plurality of channels from the centralized server, and present the videoconference signal.
- 16. A videoconference system comprising a centralized server associated with a plurality of communication channels and a dedicated control channel, said centralized server configured to receive a videoconference request signal from one of a plurality of videoconference terminals over the dedicated control channel, determine the availability of the plurality of communication channels, and assign one of the plurality of communication channels to the requesting videoconference terminal.
