AVID start [9:8]
AVID active:
0 = AVID out active in VBLK (default)
1 = AVID out inactive in VBLK
AVID start [9:0]:
AVID start pixel number, this is an absolute pixel location from HSYNC start pixel 0.
NTSC 601 default: is 85 (55h)
PAL 601 default: is 95 (5Fh)
The TVP5147M1 decoder updates the AVID start only when the AVID start MSB byte is written to. If the user changes these registers,
then the TVP5147M1 decoder retains values in different modes until this device resets. The AVID start pixel register also controls the
position of the SAV code.

AVID stop [9:8]
AVID stop [9:0]:
AVID stop pixel number. The number of pixels of active video must be an even number. This is an absolute pixel location from HSYNC
start pixel 0.
For NTSC 601, default is 805 (325h)
For PAL 601, default is 815 (32Fh)
The TVP5147M1 decoder updates the AVID stop only when the AVID stop MSB byte is written to. If the user changes these registers, then
the TVP5147M1 decoder retains values in different modes until this device resets. The AVID start pixel register also controls the position of
the EAV code.
