Digital video encoder
defines the frequency of the synthesized pixel clock PIXCLKO;

horizontal offset; defines the number of PIXCLKs from horizontal sync (HSVGC) output to composite
blanking (CBO) output
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
