Align the Subtitle Projector with the Screen
This procedure assumes that you have installed the cinema subtitling projector (CSP) and it is connected
to the XD20 with the Cinema Subtitling System (CSS) option installed.
Datasat Digital Entertainment recommends you use the test film SMPTE RP40 (flat), which is represented
by the gray (or light blue) background in Figure 2, next page.
If you don’t have the test film, you’ll have to approximate the alignment of the subtitles
projection with the horizontal and vertical centerlines of the screen.
1.
Remove masking on the CSP projector’s EMA (if present) and set it aside. (You will reinstall it
later.)
2.
Turn on the CSP using the XD20 menu (Playback
→
Film
→
CSS Playback
→
CSS Mode). (In
the CSS Mode menu, choose ON.)
3.
Turn on the film projector and run the RP40 test film.
4.
Set the RP40 test film so that the target image is correct on the screen for the format that is
playing (flat).
5.
Turn on the alignment pattern in the CSP. The image size should be 100%.
(In the XD20 menu system, select
Setup
→
CSS Projector Setup
→
Image Size
and choose
100%.) The alignment pattern will project onto the screen.
6.
Adjust the Vertical Offset to “0” (zero).
From the XD20
CSS Projector Setup
menu, select
Vertical Offset
and use the up/down arrows
to adjust the setting to “0”. Press
Enter
to activate the setting. The alignment pattern will move to
the new position when
Enter
is pressed.
7.
Adjust the zoom lens on the CSP to project the largest possible image. Focus this image. Then
adjust the zoom lens to make the image smaller, if needed, to fit inside the lower half of the
RP40 projected image area (between line1 and line 6 in Figure 2, below).
If the image is still too large when zoomed to its smallest size, adjust the image size to 90% or
80% using the Image Size menu (See step 5, above). If the resulting image is still too small,
adjust the zoom again to get the correct size.
8.
Manually adjust the position of the CSP so that the upper horizontal line (of the alignment
pattern) aligns with the horizontal centerline of the screen (line 1 in Figure 2).
The alignment pattern can be smaller, but not larger than the area bounded by lines
1 and 6. Make sure the top line of the alignment pattern is exactly horizontal, not tilted.
9.
Manually adjust the CSP so that the vertical centerline of the alignment pattern aligns with the
vertical centerline of the screen (line 7).
