OSDPixFmt
[13:11]
When GoOSD is set, specifies the pixel format for OSD
data of the associated OSD window, as shown below.
ScaleH
[10:9]
Specifies the horizontal scale factor for OSD data, as
shown below. This scaling is applied before the square
pixel scaling selected by the SqPixel bit. Square pixel
scaling is limited to pixel output rates less than or equal
to one fifth of the DMN-8600 internal clock (480P at
148.5 MHz). OSD data is scaled by duplicating pels
horizontally by the scale factor amount.
ScaleV
[8:7]
Specifies the vertical scale factor for OSD data. OSD
data is scaled by duplicating pels vertically by the scale
factor amount.
Programming
Note:
2x vertical scaling for interlaced output is best achieved by
displaying both fields of OSD data in each field–that is, both
the top set and the bottom set.
Bott
6
If set, bottom field data is displayed in OSD windows and
video out windows. If set at the same time as Top, data
from each field is displayed on alternate lines, with top
