Description
not used
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.
This flag indicates the presence of copy-guarded video
content from STBs or VCRs. It can be used for
debugging and other purposes.
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.
This flag is active, if a proper frame (50 Hz or 60 Hz) is
detected. It can be used for debugging and other
purposes.
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.
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.
