Method of transmitting data among a plurality of LSIs, and recording medium reproducing apparatus using the method

摘要

There is provided a recording medium reproducing apparatus in which a digital signal immediately before being inputted to a D/A converting LSI is prevented from being taken out and unfairly copied A digital signal processing LSI and the D/A converting LSI are connected to each other through an external bus. A scrambling processing circuit for scrambling a digital signal outputted from a digital signal processing circuit is provided inside the digital signal processing LSI. A descrambling processing circuit for descrambling the scrambled digital signal transmitted through the external bus is provided inside the D/A converting LSI.
