Figure 8-3 Domino block
A matrix switch STV6618 [7210] controlled by the Domino
Host via I
2
C-bus is used for Video I/O switching. All used
outputs excluding pin 21 (Y/CVBS-REC) have a 6dB-
ampli
fi
cation and a 75 ohms-driver-stage inside. This IC also
includes several digital outputs, which are used for switching
purposes on the Analog board.
This matrix switch routes the selected inputs to the correct
output lines for TV viewing and further processing in the
Digital board.
The record selector inside the switch selects between the
inputs from Tuner Frontend (CVBS_TV), CVBS Scart1
(CVBSIN1), CVBS Scart2 (CVBSIN2) or D_CVBS from
the DENC (on Digital board). The output signal CVBS_RE
together with the other signals CVBS_FIN, Y_FIN & C_FIN
from the Front and RCB from Scart2 are routed directly to the
VIP (on Digital board) for further processing.
The signals D_C and D_Y are fed through [7606] (6dB
ampli
fi
cation) and D_C via transistors [7213 & 7212] as driver
to the S-Video output socket. Likewise the signal D_CVBS is
fed through [7606] (6dB ampli
fi
cation) to the rear CVBS cinch
socket.
8.3. Digital
Board
The Digital Board is based on the highly integrated LSI
‘Domino’ BGA chip (Ball Grid Array), DMN-8602. This IC has
an on-chip ATAPI controller and integrates an analog video
encorder, and provides build-in support for non-simultaneous
progressive and interlaced video output. A 1394 link layer
function is also integrated so a simple external physical layer
device is required. The DMN-8602 also has a set of integrated
USB Physical Layer Interface.
The board encodes and multiplexes analogue video and
digital uncompressed audio (I
2
S) into an MPEG2 stream. This
MPEG2 stream is formatted for recording by the DVD+RW
engine. In the playback, the board will decode the MPEG2
video into analogue video. In addition, a DV stream can be
received via IEEE 1394 (i-Link), and transformed to MPEG2
format.
