PURPOSE:To continuously obtain data on the reception side even when transmitted data are temporarily interrupted by repeatedly transmitting the data plural times while compressing the pits of those data into digital data and 1/n. CONSTITUTION:Concerning digital audio data supplied from a CD player 1, the 16 bits of one sample are compressed to the 4 bits of one sample by a bit compression circuit 11, and these audio data compressed to the 1/4 data amount are repeatedly outputted four times as serial data and supplied to a transmitting data preparation circuit 12. Information concerning the output state of the compressed data is supplied from a bit compression circuit 11 to an address generation circuit 13, and the address generation circuit 13 generates address data synchronized to this supplied information and supplies these address data to the transmitting data preparation circuit 12. In the transmitting data preparation circuit 12, a bit-compressed data address is added and supplied to a transmission circuit 14. In the transmission circuit 14, this address is translated into an infrared signal and outputted by an infrared signal light emission part 15. |
