1. A/V decoder VIC1(CL6120P)
VIC1 receives DVD data compressed from DIC6(Digital protection GA) and VCD and CD data compressed
from SIC7(Servo processor) for decoding. VIC8 and VIC9(74HC157, Digital mux.) are used to select one out of
two types of signals and the control signal is DVD_SEL signal inputted from pin 83 of main micom.
DRAM(VIC3, 4, 5, 6, 7 ; KM416C254DJ-6) of 20Mbytes is used for decoding data storage and EPROM(VIC2 :
AM27C4096-120) of 4Mbytes is used to save the decoding program. The signals of PVSREQ, BSTCLK, PLRERR,
PVSACK, etc. indicate a decoding state during DVD refresh and help a smooth decoding for communication
with DIC6.
