    • An apparatus (10) for independently routing channels from a plurality of serial, digital audio data streams to corresponding channels of a plurality of predetermined serial digital audio stream outputs. Apparatus according to the invention comprise a plurality of signal inputs (421, 422, 423,...42N) for receiving serial audio data streams. Each audio data stream input may include two or more discrete channels of audio data with each input having the same number of channels. The apparatus also includes an input retiming circuit (40) to time-align corresponding channels of each input audio data stream and a switch (20) which accepts the plurality of time-aligned input data streams (721, 722, 723, ...72N) and exclusively routes predetermined channels of predetermined inputs to corresponding channels of predetermined outputs (801, 802, 803, ...80M).
    • 一种用于独立地将多个串行数字音频数据流中的信道路由到多个预定串行数字音频流输出中的相应信道的装置(10)。 根据本发明的装置包括用于接收串行音频数据流的多个信号输入(421,422,423,... 42N)。 每个音频数据流输入可以包括两个或更多个音频数据的离散声道,每个输入具有相同数量的声道。 该装置还包括输入重定时电路(40),用于对每个输入音频数据流的相应通道进行时间对准;以及开关(20),其接收多个时间对齐的输入数据流(721,722,723,...) 并且将预定输入的预定通道专用于预定输出(801,802,803,80 ... 80M)的相应通道。
