Preliminary Data Sheet
System Description
With FRSEL a colored frame is added to the inset picture. The chip can display two
different types of frames, one simple monochrome frame and a more sophisticated
frame giving a three dimensional impression.
The frame elements are always placed outside the inset picture, except for the inner
shade of three dimensional frame or inner frame in multipip-mode. There is no shift of
the inset picture position if the inset frame width is modified.
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 FRWIDHV. If desired, frame color is displayed over the whole PIP size
or whole picture size of the main channel when PIPBG is set accordingly.

Selectable picture configurations
64 background colors are programmable by BGY, BGU, BGV, 2 bits for each
component. Alternatively BGFRC sets the background to frame color.

16:9 Inset Picture Support
To remove dark stripes at 16:9 inset pictures the vertical display area is reducable with
VPSRED. The number of omitted lines depends on the vertical decimation factor.
