1. A satellite system for providing broadcast services:
- a spot beam satellite operable in a first mode to provide broadcast data to a broadcast coverage area via a plurality of spot beams and operable in a second mode to provide spot beam transmissions via the plurality of spot beams to a plurality of spot beam coverage areas, wherein when the spot beam satellite is operating in the second mode, each spot beam may transmit different data to receivers within a spot beam coverage area associated with the spot beam.

Abstract
Techniques for providing broadcast services on spot beam satellite are provided. These techniques enable the mission of a spot beam satellite system to be changed from providing spot beam transmission to broadcast transmissions, and vice versa, without requiring that the satellite be reconfigured. Broadcast data may be encoded and transmitted concurrently on a plurality of spot beams. According to some embodiments, the broadcast data may be encoded using a space-time code and/or forward error corrected (FEC) encoded to enable a receiver to correct errors in the signal received from the spot beam satellite.

13. A broadcast signal source for providing broadcast data to a spot beam satellite broadcasting system, the broadcast signal source comprising:
-
a transmitter configured to transmit a plurality of uplink signals to a spot beam satellite, wherein each of the uplink signals corresponds to a spot beam of the spot beam satellite; and a data encoder module for encoding the broadcast data such that the spot beam satellite may simultaneously broadcast the encoded data on at least a portion of the plurality of spot beams using the same frequency. - View Dependent Claims (14, 15, 16, 17, 18, 19)
