Video standard:
0000 = Autoswitch mode (default)
0001 = Reserved
0010 = (M, J) NTSC ITU-R BT.601
0011 = Reserved
0100 = (B, G, H, I, N) PAL ITU-R BT.601
0101 = Reserved
0110 = (M) PAL ITU-R BT.601
0111 = Reserved
1000 = (Combination-N) PAL ITU-R BT.601
1001 = Reserved
1010 = NTSC 4.43 ITU-R BT.601
1011 = Reserved
1100 = SECAM ITU-R BT.601
With the autoswitch code running, the user can force the device to operate in a particular video standard
mode and sample rate by writing the appropriate value into this register.

AVID stop pixel MSB [9:2]
Active video cropping stop pixel MSB [9:2], set this register first before setting the register 2Ah. The
TVP5154A decoder updates the AVID stop values only when register 2Ah is written to. This stop pixel
value is relative to the default values of the AVID stop pixel.

Active video cropping stop pixel LSB [1:0]: The number of pixels of active video must be an even number.
The TVP5154A decoder updates the AVID stop values only when this register is written to.
