Abstract
PURPOSE:To reduce the load of software of a microcomputer by directly sending sub-code data required for a transfer format for transferring digital data from a digital audio apparatus to another apparatus to a transmitter. CONSTITUTION:Digital data on a magnetic tape 15 are reproduced by a magnetic head 14 and inputted to a signal processing part 12. The processing part 12 separates the reproduced data into digital audio data and sub-code data and the digital audio data are converted into an analog signal by a digital audio D/A converter 18. On the other hand, only a part necessary for the transfer format is selected from the sub-code data and sent to the transmitter 20 together with the digital audio data. Both the signals are converted into data along the prescribed transfer format and outputted through a line driver. Since the data are not passed through the microcomputer 13, no load is applied to the software.
