– (default)
1
Cropping enabled (unscaled: 704 pixels/line, down-scaled: 352 pixels/line)
Quan_Ctrl
10-bit to 8-bit quantization control. Dithering algorithm based on truncation error from previous pixel.
00
Enable simple truncation
01
Enable dithering (default)
10
Enable simple rounding

Reserved
Line_ID_Ctrl
Line ID control. For line-interleaved mode only.
0
Line ID continues counting through the vertical blanking interval - (default)
1
Line ID holds the terminal count from the end of active video through the vertical blanking interval
Chan_ID_SAVEAV_En
Channel ID inserted in SAV/EAV codes enable, active high. For pixel-interleaved mode only. Always disabled for
non-interleaved and line-interleaved modes.
0
Disabled (default)
1
Enabled
Chan_ID_Blank_En
Channel ID inserted in blanking level enable, active high. For pixel-interleaved mode only. Always disabled for non-interleaved and
line-interleaved modes.
0
Disabled (default)
1
Enabled
Video_Det_SAVEAV_En
Video detection status inserted in SAV/EAV codes enable, active high. For non-interleaved and pixel-interleaved
modes. Always enabled for line-interleaved mode.
0
