Abstract
The present invention relates to a digital transmission system provided with a transmitter 11 and a receiver 12, wherein the transmitter 11 comprises a first clock extracting device 13, 14 for detecting a synchronizing signal contained in a first digital audio interface (DAI) format signal from the receiver 12 and generating a first clock signal of a predetermined frequency in being phase-locked with the synchronizing signal, a data read-out device 4 for reading out data from a recording medium on the basis of the first clock signal, and a first encoder 5 for encoding the data from the data read-out device 4 in a second digital audio interface (DAI) format signal on the basis of the first clock signal, while the receiver 12 comprises second clock extracting device 6, 7 for detecting a synchronizing signal contained in the second DAI format signal and generating a second clock signal of a predetermined frequency in being phase-locked with the synchronizing signal, a decoder 8 for decoding data from the second DAI format signal on the basis of the second clock signal, an oscillator 3 for generating a master clock, D/A a converter 9 for digital-to-analog converting the decoded data on…
