DATA TRANSFER METHOD AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To transfer audio data of plural channels and additional data without changing the number of data lines and increasing a load by adding a discrimination signal for discriminating a data array in which audio data of the plural channels coexist so as to transfer through the use of the number of data lines not more than the number of the usable data lines. SOLUTION: First DSP 1 divides inputted digital audio data into audio data of the respective channels to coexist audio data of the plural channels and adds the discrimination signal discriminating the data group to a data group to output by a data line. Second DSP 7 receives audio data from DSP 1 and separates transferred audio data into each audio data without the burden of processing such as arithmetic to output. Consequently audio data of the plural channels are transferred by simple constitution and without giving any load to DSPs 1 and 7.
