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; IC2601, which selects the video input signals and IC2602, which

selects the audio input signals. Composite video, luminance and

chrominance signals from the digital tuner pass through the DG board and

enter IC2601 of the H board via the connector H1/DG1. 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.
