    • A wireless digital audio distribution system includes a transmitter that performs parallel acquisition of audio data from plural audio data channels. The acquired data is stored to a first buffer during intervals defined by a first clock unit. A radio transmitter provides for the packetization of the parallel collected data and the inclusion of a timing marker in a predetermined packet of data transmitted during an interval. A receiver unit delivers audio output data corresponding to one of the audio data channels. The receiver unit includes a radio receiver for receiving packetized data and storing second parallel collected data to said second buffer. A demultiplexer is coupled to the second buffer to select the audio output data corresponding to the selected one of the plural audio data channels, whereby the audio output data is available for the selective reproduction of the chosen audio data channel.
    • 无线数字音频分配系统包括执行来自多个音频数据信道的音频数据的并行获取的发送器。 所获取的数据在由第一时钟单元定义的间隔期间被存储到第一缓冲器。 无线电发射机提供并行收集的数据的分组并且在时间间隔期间发送的预定数据分组中包括定时标记。 接收机单元传送对应于音频数据信道之一的音频输出数据。 接收器单元包括用于接收分组数据并将第二并行收集的数据存储到所述第二缓冲器的无线电接收器。 解复用器耦合到第二缓冲器以选择对应于多个音频数据通道中的所选一个的音频输出数据,由此音频输出数据可用于选择性再现所选择的音频数据通道。
