ABSTRACT:
The present invention relates to a transmission device and a transmission method which can efficiently perform transmission of audio signals with infrared ray and suppress the complication of data processing in modulation and demodulation processes to the minimum level. Audio signals reproduced by a digital audio instrument are transmitted to and recorded into a digital audio recorder through an audio signal transmission device by infrared ray. In the digital audio recorder, the recorded audio signals are immediately reproduced, transmitted and output to a digital audio instrument through an audio transmission device with infrared ray. In the transmitters, a transmission channel clock having the frequency of 5/4-times the data clock thereof from the audio signals, and modulated signals obtained by modulating the audio signals are output at the timing of the transmission channel clock.
