Hi, all
If a progressive frame of data is stored in DDR , and I want to
output to a interlaced device such as NTSC mode TV, how can I achieve
this?
I just set the
VIDWINMD.VFF0/VIDWINMD.VFF1/OSDWIN0MD.OFF0/OSDWIN1MD.OFF1 to a field
mode and set the VMOD.ITLC to interlaced mode, also set the
osd_winYL(window height register) to 1/2 display height. but I can see
about 1/2 picture from the TV. if set osd_winYL to display height,
then output a mess-up picture. So how to display a progressive frame
in a interlace display device? Thanks for any comments.
