System and method for selecting channels for short range transmissions to broadcast receivers
First Claim
1. A method of identifying transmission channels for short range broadcasts to broadcast receivers, comprising:
- providing a transmitter configured to provide short range broadcasts to an external broadcast receiver configured to tune channels within a broadcast signal spectrum;
using a receiver to scan a plurality of channels within the broadcast signal spectrum;
determining for each channel a level of received signal strength for that channel;
comparing the received signal strength for each channel to a threshold power level, the threshold power level correlating to a transmit power for the transmitter;
identifying one or more channels that have received signal strengths below the threshold power level; and
outputting an indication these one or more channels.

Abstract
Methods and systems for determining transmission channels for short range transmissions are disclosed. A transmitter provides short range transmission to a broadcast receiver configured to receive and tune channels within a signal spectrum. Channels within the broadcast signal spectrum are scanned, and an indication of received signal strength is obtained for each channel. The received signal strength indication (RSSI) can then be compared to a threshold power level that correlates to a signal level that the transmitter will be capable of overpowering based upon the transmission power of the transmitter. The scan results in an indication of one or more channels that have received signal strengths below the threshold power level of the transmitter.

12. A system for providing short range broadcast to broadcast receivers, comprising:
-
a transmitter configured to provide short range broadcasts to a broadcast receiver configured to tune channels within a broadcast signal spectrum; a receiver configured to receive and tune channels within the broadcast signal spectrum; receive signal strength indication circuitry configured to determine a received signal strength for a channel tuned by the receiver; and control circuitry coupled to the receive signal strength indication circuitry and configured to compare the received signal strength for each channel to a threshold power level value correlating to a transmit power for the transmitter and to output an indication of one or more channels that have received signal strengths below the threshold value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
