Subaddress 1C
Function
Vertical decimation of the input data stream:
111: not used
110: factor 4.0
101: factor 3.0
100: factor 2.0
011: factor 1.75
010: factor 1.5
001: factor 1.25
000: off
(In case of VDECON>0, spatial noise reduction as well as the motion
detection for scan rate conversion are disabled)
Horizontal decimation of the input data stream:
11: not used
10: factor 4.0
01: factor 2.0
00: off
(In case of HDECON>0, spatial noise reduction as well as the motion
detection for scan rate conversion are disabled)
Automatic movie mode for the motion detection for the scan rate
conversion:
In case of movie mode, the motion detection for scan rate conversion will
be automatically switched to
11: no motion
10: only frame difference
0X: off
Motion detection for the scan rate conversion:
1: based on frame difference and field difference
0: based only on frame difference
(In case of AMMON>1 and no movie mode, the motion detection for scan
rate conversion is still defined by FRAFION)
