Description
Detection data
First data=0045h[0]
Number of data items the intermediate values of which are detected
(from the 600 kHz LPF signal)
Number of data items the intermediate values of which are detected
(from the 6 MHz LPF signal)
The number of line where the data is detected
00: Not detected 01: 20(283)H 10: 21(284)H 11: 22(285)H
Result of Clock Run-In detection
0: Not detected 1: Detected
Reliability of the detection result
0: Not good
1: OK (The imccdet bit is set to 0 and all data fixed)
Description
Color killer use
1/4 of the number of lines with no burst gate generated during a
period of 128H.
Color killer use
The total number (absolute value) of APC errors resulted during a
period of 128H.
Result of detection of weak electromagnetic field sync noise
(The number of pulses in the sliced and binary-coded Csync in a
single field)
Standard signal discrimination
(Discriminated as a standard signal if the number of clocks per 1H
period is within a range of 910±7.)
0: Standard 1: Nonstandard
Field discrimination
0: Second field (even) 1: First field (odd)
Signal detection result
0: Detected 1: Not detected
Result of weak electromagnetic field detection
The integrated noise value (0 to 255) in a period of 6H V-blanking.
Discrimination of frame skipping in the frame sync block
0: No skip 1: Skipped
Discrimination of frame hold in the frame sync block
0: No hold 1: Hold
