发明名称 Wireless output input device player
摘要 A wireless output input device (WOID) digital audio player for storing and/or receiving digital audio and preserving the digital stream without the inherent distortion of translating the stream to analog prior to modulation and transmission, which includes an FM receiver, and an FM transmitter for transmitting the audio to an external FM radio or receiver. The device automatically and periodically scans a plurality of channels on the FM band to determine the channel having the least amount of interference and then tunes the FM transmitter to the frequency of that channel and displays the channel to which the external receiver should be tuned. A remote control may be provided to selectively transmit signals to the player's FM receiver for controlling operation of the player.
