AVID start [9:8]
AVID start [9:0]
AVID start pixel number, this is a absolute pixel location from HS start pixel 0.
The TVP5158 updates the AVID start only when the AVID start MSB byte is written to. AVID start pixel register also controls the
position of SAV code. If these registers are modified, then the TVP5158 will retain the values for each video standard until the
device is reset. The values for a particular video standard should be set by forcing the TVP5158 to the desired video standard first
using register 0Dh then setting this register. This should be repeated for each video standard where the default values need to be
changed.

AVID pixel width. The number of pixels width of active video must be an even number. This is an absolute pixel location from HS
start pixel 0.
The TVP5158 updates the AVID pixel width only when the AVID pixel width MSB byte is written to. AVID pixel width register also
controls the position of EAV code. If these registers are modified, then the TVP5158 will retain the values for each video standard
until the device is reset. The values for a particular video standard should be set by forcing the TVP5158 to the desired video
standard first using register 0Dh then setting this register. This should be repeated for each video standard where the default
