(3) Zoom mode
In this mode, 4:3 images are reproduced on a 16:9 CRT by enlarging the picture without other modification. The
top and bottom of normal 4:3 images are lost, but almost the entire pieture can be reproduced for vista size video
software, etc. which already has black borders at the top and bottom. Setting the ASPECT register to 2Fh (100%)
allows zooming to be performed for 4:3 images without distortion. In this case, the number of scanning lines is
reduced to 360 Iines compared to 480 Iines for full mode. The zooming position can be shifted vertically by the
SCROLL register.
V blanking of the image normally begins from V sync and continues for 2H after the AKB reference pulse, and the
top and bottom parts are also blanked during this mode.
Adjust the following two registers with respect to the 16:9 CRT standard values for the register settings.
ASPECT = 2Fh
SCROLL = 1Fh or user control
(4) Subtitle-in mode
When CinemaScope size images which have black borders at the top and bottom of the picture are merely
enlarged with the zoom mode in (3) above, the subtitles present in the black borders may be lost. Therefore, this
mode is used to super-compress only the subtitle part and reproduce it on the display.
Add the LOWER VLIN adjustment to the zoom mode settings for the register settings.
ASPECT = 2Fh
SCROLL = 1Fh or user Control
LOWER VLIN = Adjustment value
LOWER VLIN causes the linearity at the bottom of the picture to deteriorate. Therefore, UPPER VLIN should also
be adjusted if the top and bottom of the picture are to be made symmetrical. Since the picture is compressed
vertically, the number of scanning lines exceeds 360 lines.
(5) Two-picture mode
This mode is used to reproduce two 4:3 video displays on a 16:9 CRT such as for P and P.
To achieve this, the V size must be further compressed from the condition where ASPECT = 0 (V size 75%: full
mode). This IC performs this compression with V UNDER SCAN.
16:9 CRT standard values are used with only V UNDER SCAN changed to "1" for the register settings.
V UNDER SCAN = 1
(6) Wide zoom mode
This mode reproduces 4:3 video software naturally on wide displays by enlarging 4:3 images without other
modification and compressing the parts of the image which protrude from the picture into the top and bottom parts
of the picture. The display enlargement ratio is controlled by ASPECT, and the compression ratios at the top and
bottom of the picture are controlled by UPPER VLIN and LOWER VLIN.
Adjust the following three registers with respect to the 16:9 CRT standard values for the register settings.
ASPECT = Adjustment value
UPPER VLIN = Adjustment value
LOWER VLIN = Adjustment value
(7) 4:3 CRT normal mode
This is the standard mode for 4:3 CRTs.
The register settings are the 4:3 CRT standard values.
