Abstract

A method and apparatus for performing satellite selection in a broadcast communication system is provided. In some embodiments, a controlling data stream broadcast on a first satellite over a broadcast channel is utilized to indicate that information signals such as a television program are being carried on the same channel on a different satellite. Remote receiving apparatus utilize the controlling data stream to locate the information signals by switching to the satellite identified in the controlling data stream.

Claims

1. For use in a broadcast communication system for delivering a plurality of channels of information to a plurality of remote receiving apparatus, a method of facilitating satellite selection by the remote receiving apparatus comprising the steps of:

broadcasting an information signal over a first channel on a first satellite; and

,

broadcasting a controlling data stream over the first channel on a second satellite, the controlling data stream including information identifying the first satellite as carrying the information signal whereby, if a remote receiving apparatus tunes to the first channel on the second satellite, the identifying information contained in the controlling data stream directs the remote receiving apparatus to tune to the first channel on the first satellite.

2. A method as defined in claim 1 wherein the plurality of remote receiving apparatus each include first and second antenna receiving elements and first and second input ports, and further comprising the step of predefining an order in which the first and second antenna receiving elements are coupled to the first and second input ports for each of the remote receiving apparatus within the broadcast communication system.

3. A method as defined in claim 2 wherein the identifying information identifies the first satellite by identifying the first input port of the remote receiving apparatus and wherein the first antenna receiving element is directed at the first satellite and is coupled to the first input port.

4. A method as defined in claim 2 wherein the identifying information identifies the first satellite by identifying a frequency and polarization of the first channel and an orbit location of the first satellite.
