A receiving device for receiving a satellite broadcast comprising: a receiver for receiving a sustaining satellite beam; and a controller for switching the receiver to receive a high power content beam in response to a determination that the high power content beam can be received by the receiving device. A communication satellite transmits the high power content beam to different geographical areas at different times. The sustaining beam allows the receiving device to remain synchronised with the communication satellite when the high power content beam is directed elsewhere. The sustaining beam may be a lower power beam. The determination that the high power content beam can be received may be performed based on information in the sustaining beam. Alternatively or additionally, the determination that the high power content beam can be received may be made by monitoring the signal strength of a frequency associated with the high power content beam.
