PROBLEM TO BE SOLVED: To enable the execution of correct processing of data between data processing parts even when there are not special circuits for the interface of external circuits or the like in the data processing parts by adding attribute data peculiar to transmission data, for example, data of an L channel and an R channel. SOLUTION: Digital audio data processing parts A, B are constituted of DSPs(digital signal processors) respectively and the communication of digital audio data is performed between them through a communication lines C. In this case, e.g. in 32-bit undata periods of the audio data, attribute data (statuses) indicating attributes of data just before the periods are added and the audio data are transmitted. Consequently, for example, when L channel and R channel are added to the status of data A and to the status of data B respectively in the digital audio data processing part A and the audio data are transmitted, the digital audio data processing part B ca easily distribute the respective data A, B as the data of the portion of the L channel and the portion of the R channel by viewing the respective statuses. |
