All data during vertical blanking
is replaced with black (Y =
0x40, C = 0x200)
Only active lines are digitized.
If input video is NTSC, HD10AVA
also digitizes the luminance data
present on lines 10-20 and lines
272-283, in addition to normal active
video lines.
If input video is PAL, HD10AVA also
digitizes the luminance data present
on lines 6-22 and lines 318-335 in
addition to normal active video lines.
