NOISE_DET R
-
This flag gets HIGH in case the video S/N (weighted)
drops below 30 dB. For proper and noise free video
signals it stays LOW. It can be used for debugging and
other purposes.
4
MAC_DET
R
-
This flag indicates the presence of copy-guarded video
content from STBs or VCRs. It can be used for
debugging and other purposes.
3
FIDT
R
-
This flag indicates the frame rate (50 Hz or 60 Hz).
When active, 60 Hz is detected. It can be used for
debugging and other purposes.
2
V_LOCK
R
-
This flag is active, if a proper frame (50 Hz or 60 Hz) is
detected. It can be used for debugging and other
purposes.
1
F_H_LOCK
R
-
This flag is active, if a proper H-sync (15.625 kHz or
15.734 kHz) is detected (Fast mode). It can be used for
debugging and other purposes.
0
N_H_LOCK
R
-
This flag is active, if a proper H-sync (15.625 kHz or
15.734 kHz) is detected (Normal mode). It can be used
for debugging and other purposes.
