System for providing signals from an auxiliary audio source to a radio receiver using a wireless link
First Claim
1. A system for providing audio signals to a radio receiver from an auxiliary audio source comprising:
- an input for receiving said audio signals from said auxiliary audio source;
a processing device connected to said input and operable to substantially continuously monitor a selected radio frequency spectrum to identify radio frequency channels that satisfy a predetermined open channel criteria, and to automatically select at least one radio frequency satisfying said predetermined open channel criteria at which to transmit said audio signals to said radio receiver via a wireless link, and to modulate said audio signals on said selected radio frequency; and
an antenna connected to said processing device and operable to transmit said audio signals to said radio receiver using said at least one radio frequency;
wherein said processing device further comprises an output device for indicating said at least one radio frequency to a user to allow said user to tune said radio receiver to said at least one radio frequency.

Abstract
An apparatus and method are provided for transmitting audio signals from an auxiliary source such as a satellite broadcast receiver or a CD or cassette player to a radio receiver located, for example, in a vehicle, using a wireless link. The apparatus comprises a scanning device for locating open radio frequencies in the RF spectrum of the radio receiver. The apparatus displays plural RF channel options on a display device and provides a selection device with which a user selects an RF channel. The apparatus modulates the audio signals using the selected radio frequency, and the user tunes the vehicle radio receiver to the selected RF channel. The scanning device continuously scans for open RF channels and monitors the quality of the RF channel already selected for use as the wireless link. The apparatus provides the user with an indication to select another open channel when the RF channel in use degrades.
