    Abstract: 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.

    Abstract translation: 一种无线输出输入设备(WOID)数字音频播放器,用于存储和/或接收数字音频并保留数字流,而无需在调制和传输之前将流转换为模拟的固有失真,包括FM接收机和FM发射机 用于将音频发送到外部FM收音机或接收机。 设备自动和周期地扫描FM频带上的多个频道以确定具有最小干扰量的信道,然后将FM发射机调谐到该频道的频率,并显示外部接收机应被调谐到的频道。 可以提供遥控器以选择性地向玩家的FM接收器发送信号,以控制玩家的操作。
