Digital video encoder
pixel in X direction; defines half the number of active pixels per input line (identical to the length of
CBO pulses)
vertical offset in odd field; defines (in the odd field) the number of lines from VSVGC to first line with
active CBO; if no LUT data is requested, the first active CBO will be output at YOFSO + 2; usually,
YOFSO = YOFSE with the exception of extreme vertical downscaling and interlacing
vertical offset in even field; defines (in the even field) the number of lines from VSVGC to first line with
active CBO; if no LUT data is requested, the first active CBO will be output at YOFSE + 2; usually,
YOFSE = YOFSO with the exception of extreme vertical downscaling and interlacing
defines the number of requested input lines from the feeding device;
number of requested lines = YPIX + YOFSE

frame sync signal at pin FSVGC ignored in slave mode
frame sync signal at pin FSVGC accepted in slave mode
normal polarity of CBO signal (HIGH during active video)
inverted polarity of CBO signal (LOW during active video)
the SAA7104E; SAA7105E is timing master to the graphics controller
the SAA7104E; SAA7105E is timing slave to the graphics controller
if hardware cursor insertion is active, set LOW for non-interlaced input signals
if hardware cursor insertion is active, set HIGH for interlaced input signals
luminance sharpness booster disabled
