Abstract:
A method of transmitting, in a DVD-Audio reproducing apparatus comprising a digital signal processing LSI and a D/A converting LSI which are connected to each other through an external bus for reproducing a DVD-Audio disk, a digital signal from the digital signal processing LSI to the D/A converting LSI through the external bus, comprising the steps of:processing inside the digital signal processing LSI the digital signal which has been read out of the DVD-Audio disk; scrambling inside the digital signal processing LSI the digital signal which has been processed; transmitting the scrambled digital signal from the digital signal processing LSI to the D/A converting LSI through the external bus; descrambling inside the D/A converting LSI the scrambled digital signal transmitted through the external bus; and converting inside the D/A converting LSI the digital signal which has been descrambled into an analog signal.
