    • At a transmission side, an encoder 4 codes data of each channel and inserts a special character attributing to each channel. A character multiplex circuit 5a byte multiplex each channel for outputting. At a reception side, a character synchronization circuit 9 synchronized with a character by detecting the special character. A character demultiplex circuit 10a demultiplexes a signal by a character byte and obtains data of each channel. A channel identification circuit 11 identifies each channel by detecting the special character attributing to the channel without bit rotating for synchronization. A decoder 14 executes decoding without bit rotating and outputs a signal from a channel demultiplex circuit.
    • 在发送侧,编码器4对每个通道的数据进行编码,并插入属于每个通道的特殊字符。 字符多路复用电路5a字节复用每个通道用于输出。 在接收侧,通过检测特殊字符与字符同步的字符同步电路9。 字符解复用电路10a通过字符字节解复用信号,并获得每个通道的数据。 信道识别电路11通过检测属于信道的特殊字符来识别每个信道,而不进行位旋转以进行同步。 解码器14执行无位旋转的解码,并输出来自信道解复用电路的信号。
