Video Input Selection Block Diagram
Figure 20
The H board contains the Video inputs 1, 2, and 3, Component Video Inputs 1 and 2,
and the Program Out jacks. All the Audio/Video input signals are applied to this board
for selection. There are two input selection ICs on this board; IC2602, which selects the
video input signals and IC2605, which selects the audio input signals. Video signals
from the digital tuner and the HDMI receiver board (DV board) pass through the DG
board and enter IC2602 of the H board via the connector H2/DG2. The selected video
signals are output to the DG Board without alteration. The output signals can be in any
of the three formats; Video, Y/C, or Y, Pb, Pr.
The PC input signal simply passes through the H board and enter the DG board via the
same connector. Selection between PC and other input signals takes place on the DG
board.
