2-1-4. AD Adjustment of CVBS Video (NTSC)
System
1) Set input to AV1.
2) Input NTSC 50% window Signal 90 IRE in AV1.
3) Set picture quality mode to [PC/GAME].
Send “RGB Level” Command.
4) Adjust Y_OUT_LEVEL until the Green detection value is
within a setting value.
Detection setting value: 197 ± 3
5) Set Video Signal to NTSC 50% window 20 IRE.
6) Adjust Cb_OFFSET1 until the detection value of Blue
becomes same as that of Green.
7) Adjust Cr_OFFSET1 until the detection value of Red becomes
same as that of Green.
8) Repeat step 6-7 until it becomes the following detection
setting value.
Detection setting value: 44
R,G,B detection value dispersion: ± 1
9) Repeat step 2-7 until it is in the detection setting value of 4)
and 8).
10) Input NTSC 75% Color Bar signal into AV1. (Fig. 1)
