Bit Description
MUX2[2:0]; manual
muxing control for MUX2;
this setting controls which
input is routed to the ADC
for processing
Reserved
MAN_MUX_EN; enable
manual setting of the
input signal muxing
LB_TH[4:0]; sets the
threshold value that
determines if a line is
black
Reserved
LB_EL[3:0]; programs the
end line of the activity
window for LB detection
(end of field)
LB_SL[3:0]; programs the
start line of the activity
window for LB detection
(start of field)
ST_NOISE[10:8]
ST_NOISE_VLD
ST_NOISE[7:0]
SD_OFF_Cb[7:0]; adjusts
the hue by selecting the
offset for the Cb channel
SD_OFF_Cr[7:0]; adjusts
the hue by selecting the
offset for the Cr channel
SD_SAT_Cb[7:0]; adjusts
the saturation by affecting
gain on the Cb channel
SD_SAT_Cr[7:0]; adjusts
the saturation by affecting
gain on the Cr channel
NVBEG[4:0]; number of
lines after l
to set V high
NVBEGSIGN
NVBEGDELE; delay V bit
going high by one line
relative to NVBEG (even
field)
NVBEGDELO; delay V bit
going high by one line
relative to NVBEG (odd
field)

Default threshold for the detection of
black lines
01101 to 10000—increase threshold,
00000 to 01011—decrease threshold
Set as default
LB detection ends with the last line of
active video on a field, 1100b: 262/525
Letterbox detection aligned with the
start of active video, 0100b: 23/286 NTSC
