001 = 8-bit 4:2:2 YCbCr
010 = 8-bit BT.656
011 = 16-bit linear RGB
100 = 16-bit gamma-corrected RGB
101 = 24-bit linear RGB
110 = 24-bit gamma-corrected RGB
111 = Blue screen
These bits are ignored except during linear RGB input modes.
0 = 1 / 2.2
1 = 1 / 2.8
These bits must be set to “11” in 24-bit RGB input modes. Internal mixing should not be
selected in BT.656 input mode.
00 = No mixing
01 = Internal mixing
10 = External mixing
11 = Disable overlays
This bit must be set to “0” during BT.656 input mode and when the flicker filter is enabled.
0 = Full resolution (2X upscaling disabled)
1 = SIF resolution (2X upscaling enabled)
0 = None
1 = Y Lowpass filtering enabled
0 = None
1 = Lower limit of composite active video is about half the sync height
0 = Never reset SCH phase
1 = Reset SCH phase every 4 (NTSC) or 8 (PAL) fields
0 = Don’t add blanking pedestal to RGB output
1 = add blanking pedestal to RGB output
0 = use HMP8156 assignments
1 = SCART connector compatible
This bit is ignored unless flicker filtering is enabled. This bit is ignored on the HMP8156.
0 = First line of active video in odd fields is on an odd line number
1 = First line of active video in odd fields is on an even line number
These bits must be “00” during 8-bit YCbCr and BT.656 input modes, and SIF input resolution
mode. These bits are always “00” on the HMP8156A.
00 = No flicker filtering
01 = reserved
10 = reserved
11 = 3-line flicker filtering enabled
000 = 16-bit 4:2:2 YCbCr
