System Description
Preliminary Data Sheet
4096 frame colors are programmable by
FRY
,
FRU
, and
FRV
, 4 bits for each
component. Horizontal and vertical width of the frame are programmable independently
by
FRWIDH
and
FRWIDV
. If desired, frame color is displayed over the whole PIP size
or whole picture size of the main channel when
PIPBG
is set accordingly. 64 background
colors are programmable by
BGY
,
BGU
,
BGV
, 2 bits for each component. Alternatively
BGFRC
sets the background to frame color.
4.8.4
To remove dark stripes at 16:9 inset pictures the vertical display area is shrinkable with
VPSRED
. The number of omitted lines depends on the vertical decimation factor.

4.8.5
The phase of the output signals is locked to the rising edge of the horizontal sync pulse.
The frequency varies in a certain range to ensure correct aspect ratio for 16:9
applications depending on
HZOOM
. The horizontal and vertical scaling can be used for
all display frequencies.
