2-9.2. 1080I HD MODE ADJUSTMENT
1. Input a 1080i cross-hatch signal and an HD monoscope signal that
contains overscan markers.
2. Adjust the raster position per Section 2-8., only if this procedure was
not performed for full mode.
3. Adjust the geometry similar to Full DRC mode. Vertical size is 11.7
± 0.1 sq. and horizontal size is 15.6 ± 0.1 sq., if monoscope signal is
available. Otherwise, set the Vertical size to 91.0 ± 0.6% scan and
Horizontal size as 91.0 ± 0.6% scan.
4. Use the following register to adjust the horizontal parameter:
A2150-D2 01 HPOS
NOTE : If necessary, touch up the geometry using the data register
listed above for Full mode. Check NTSC full mode for side
effect and balance.
5. Write the data into memory before changing modes.
2-9.3. VERTICAL COMPRESSED MODE
CHECK AND CONFIRMATION
(FOR 4X3 CRT ONLY)
1. Input a monoscope and crosshatch signal.
2. Check vertical compressed mode.
3. Adjust VPIN if needed.
2-9.4. TWIN MODE/FAVORITE/INDEX/
NORMAL MODE GEOMETRY
CONFIRMATION
TWIN mode and FAVORITE mode use the FULL mode adjustment data.
The key point for TWIN mode adjustment is the blue border appearance.
The left border on the left picture should not be visible when the left
picture is selected. Similarly, the right border on the right picture should
not be visible when the right picture is selected. Balance the HPOS or
HSIZ data for FULL and TWIN mode.
For INDEX mode, however, no clipping of the picture edge should be
visible for the small sampled pictures on the right side. Adjust HSIZ/
HPOS to balance FULL and INDEX mode for this. Avoid displaying the
edge of the raster in FULL or FAVORITE mode.
