• U1 (MPEG2 Encoder/Decoder) diverges from the 13.5MHz crystal, then generates
VSYNC and HSYNC.
• U1 does RGB encoding, copy guard processing and D/A conversion of 10bit Video
signal converted into analog signal is outputted via amplifer of analog part.
• U1 inputted from pin 131 with 13.5MHz generates HSYNC and VSYNC which are
based on video signal. U1 is synchronous signals with decoded video signal.
• The above signals, which are CVBS (Composite Video Burst
Synchronized),Y(S_Video),C(S_Video),Y(Component)/G(Green),Cr(component)/R(Red),
Cb(component)/B(Blue), are selectively outputted 576i(interlaced Video Output),
576P(progressive Video Output).
• U1 adopts 10bit D/A converter. U1 perform video en- coding as well as copy
protection.
• IC216(HA118827) switch whole the I/O signals of jack block. This switch IC is
controlled by I2C protocol between FIC1(IO front micom).
