Weak signal detection
PAL switch polarity
Field sequence status
Color killed
Macrovision detection [2:0]
Weak signal detection:
0 = No weak signal
1 = Weak signal mode
PAL switch polarity of first line of odd field:
0 = PAL switch is zero.
1 = PAL switch is one.
Field sequence status:
0 = Even field
1 = Odd field
Color killed:
0 = Color killer not active
1 = Color killer activated
Macrovision detection [2:0]:
000 = No copy protection
001 = AGC pulses/pseudo syncs present (type 1)
010 = 2-line colorstripe only present
011 = AGC pulses/pseudo syncs and 2-line colorstripe present (type 2)
100 = Reserved
101 = Reserved
110 = 4-line colorstripe only present
111 = AGC pulses/pseudo syncs and 4-line colorstripe present (type 3)

Fine gain [11:0]: This register provides the fine gain value of sync channel. See FGAIN 1 [11:0] in the AFE fine
gain for Pb_B register at subaddress 4Ah–4Bh (see Section 2.11.52).
1111 1111 1111 = 1.9995
1000 0000 0000 = 1
0010 0000 0000 = 0.5
Coarse gain [3:0]: This register provides the coarse gain value of sync channel. See CGAIN 1 [3:0] in the AFE
coarse gain for CH1 register at subaddress 46h (see Section 2.11.48).
1111 = 2
0101 = 1
0000 = 0.5
These AGC gain status registers are updated automatically by the TVP5146M2 decoder with AGC on. In
manual gain control mode these register values are not updated by the TVP5146M2 decoder.
