Abstract:

Broadcasts over designated bands of the radiofrequency spectrum allow for flexible use of the spectrum as well as for the receipt of return signals from receivers. To obtain return signals, information indicating one or more return channels and/or one or more return time windows may be sent with the broadcast transmission. The broadcast transmission may be made over UHF bands, with the return signals being made over VHF bands. Spectrum may be utilized more efficiently by transmitting one or more beacon signals that define parameters for the broadcast transmission. Receivers may be adapted to decode the data of the beacon signals and rapidly tune to the broadcast transmission.
