Signal
Function
C-GUARD
Detects copy guard (pseudo SYNC).
0: No copy guard detected 1: Copy guard detected
Detects whether input signal has copy-guard signal in the systems of 60-Hz 525 I/P, 60-Hz 1125 I, and
60-Hz 750 P, but does not detect copy-guard of HD/VD input signal.
N-DET
Detects noise.
0: Small amount detected 1: Large amount detected
Set noise detection level in NOISE LEVEL.
N-DET is detected only when 525I Y or CVBS signal is input.
V-STD
Detects NTSC standard/non-standard.
0: Standard detected 1: Non-standard detected
Detects vertical-sync-signal input in standard cycle. V-STD is detected only when 525I Y or CVBS
signal is input.
H-LOCK
Detects H-LOCK.
0: Unlock detected 1: Lock detected
Detects lock/unlock of input signal and H-AFC.
H-LOCK is detected in the systems of 60-Hz 525 I/P, 60-Hz 1125 I, and 60-Hz 750 P.
Note: This register may show UN-LOCK, when H-SYNC width of 525I Y or CVBS input is narrow.
HD-OUT
Detects HD-OUT (pin 17) self-diagnosis.
0: NG (no signal) 1: OK (signal detected)
VD-OUT
Detects VD-OUT (pin 15) self-diagnosis.
0: NG (no signal) 1: OK (signal detected)
SYNC-IN
Detects SYNC IN (pins 2 and 4 or 30) self-diagnosis.
0: NG (no signal) 1: OK (signal detected)
At small signal, NG.
Y1/2-IN
Detects Y1/2 IN (pin 2 or 4) self-diagnosis.
0: NG (no signal) 1: OK (signal detected)
At small signal, NG.
Y3-IN
Detects Y3 IN (pin 30) self-diagnosis.
0: NG (no signal) 1: OK (signal detected)
At small signal, NG.
D-SYNC2
Detects D-SYNC2 IN (pin 6) self-diagnosis.
0: NG (no signal) 1: OK (signal detected)
At small signal, NG.
H-STAB
Detects stability of horizontal signal.
0: Stable 1: Not stable
Determines not stable when fluctuation of horizontal signal is detected within one field.
H-STAB is detected only when 525I Y or CVBS signal is input.
V-SYNC
Detects vertical sync of input signal.
0: No vertical sync detected 1: Vertical sync detected
Detects whether input signal has vertical sync.
V-SYNC is detected in the systems of 60-Hz 525 I/P, 60-Hz 1125 I, and 60-Hz 750 P.
ACC
Detects status of automatic color control (ACC) circuit.
0: Maximum 1: Other
ACC is detected only when NTSC signal is input.
