发明名称 SYSTEM FOR PROVIDING SIGNALS FROM AN AUXILIARY AUDIO SOURCE TO A RADIO RECEIVER USING A WIRELESS LINK
摘要 An apparatus and method are provided for transmitting audio signals from an auxiliary source (16) such as a satellite broadcast receiver or a CD or cassette player to a radio receiver (24) located, for example, in a vehicle, using a wireless link (15). 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 (36) and provides a selection device (30, 32 and 34) 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.
