Description
Result of AGC pulse detection
0: No 1: Yes
Result of color stripe phase detection
00: 0° 01: 90° 10: 180° 11: 270°
Result of detection of the number of color stripe groups per field
Result of detection of the color stripe split position
00: No 01: Latter half 10: First half 11: Indefinite
Result of detection of the number of color stripe lines per field
(Implement the spcnt/spgcnt based on the result of spcnt and spgcnt
detection. Then determine if the 4- or 2-line mode is set.)
Result of detection of sync reduction
00: V=H 01: H>V 11: V>H

Description
Detection data
First data=0043h[0]
Number of data items the intermediate values of which are detected
(from the 600 kHz LPF signal)
(Number of bits out of the 14 data bits)
Number of data items the intermediate values of which are detected
(from the 6 MHz LPF signal)
(Number of bits out of the 14 data bits)
The number of line where the data is detected
00: Not detected 01: 19(282)H 10: 20(283)H 11: 21(284)H
Result of reference pulse detection
0: Not detected 1: Detected
Reliability of the detection result
0: Not good
1: OK (The imvwdet bit is set to 1 and all data fixed with CRC
added.)

00: Not detected 01: 19(282)H 10: 20(283)H 11: 21(284)H
Result of Clock Run-In detection
0: Not detected 1: Detected
Reliability of the detection result
0: Not good
1: OK (The imvwdet bit is set to 1 and start code and bi-phase
acceptable)
