13-4 Video Input
13-4-1 Video Input Outline
DVD-R129 is the two AV Video input. AV 1 Video input is CVBS1 & S-Video1 at the Rear Panel. Line 2 Video
input is CVBS2 at the Front Panel.
The analog Video signal select AV 1 or AV 2 by the IC601 (Front Micom).
TIC1 (Video Decoder) diverges from the 27MHz crystal, then generates ITU-R656 (10bits) and
27MHz clock. VIC1 (Video Decoder) does closed caption, copy guard detect processing and A/D conversion
of analog Video signal converted into 11bit Digital Video signal (ITU-R656 Format) is outputted via DIC1 (MPEG2
Decoder &Encoder with video Encoder) of digital part.
