Abstract:
For use with a broadcast communication system for delivering a plurality of channels to a plurality of remote users, a remote receiving apparatus comprising:an output port;a first antenna receiving element for receiving information from the broadcast communication system;a logic circuit coupled to the first antenna receiving element and having an associated memory and an associated tuner, the tuner being adapted to select a tuned channel from the plurality of channels, the logic circuit receiving a viewer-channel-to-broadcast-channel (VCBC) map and storing the VCBC map in the memory, the VCBC map mapping a first controlling data stream to a first one of the plurality of channels and a second controlling data stream to a second one of the plurality of channels, wherein, when the tuner selects the first one of the channels, the logic circuit addresses the VCBC map and outputs the first controlling data stream to the output port and, when the tuner selects the second one of the channels, the logic circuit addresses the VCBC map and outputs the second controlling data stream to the output port, the second controlling data stream being structured to direct performance of a non-tuning operation.
