Abstract
Satellite broadcasting methods include providing a cellular satellite communications system configured to transmit information separately to a plurality of different geographic locations defined by a respective plurality of cellular satellite spotbeams, and concurrently transmitting a program signal on a plurality of different spotbeams. The plurality of different spotbeams may include less than a total number of spotbeams of the cellular satellite communications system. The plurality of different spotbeams may be selected adaptively from an available pool of spotbeams based on locations of users requesting the broadcast program signal. Corresponding satellite gateways, broadcast controllers and wireless user terminals are also provided.
