• When the unit is in SG MODE, do NOT input signals to INPUTs 4-6.
• The setting of the Y/C separation function should be set to the NTSC during the VDEC SG mode.
• Only the component and RGB signals can be output during SG mode, so only the Y signal is input at the CVBS signal mode, thus
the picture is composed in black and white color. This isn't a failure.
• ANA AD RGB (the route for inputting the 525i RGB signal to AD) in SG MODE is a setting for a nonexistent route for the unit.
Therefore, there is no setting value at the stages after the MVDEC. For this reason, there may be discoloration of the color bars or
slow change of the luminance after SG MODE is set to ANA AD RGB, but it is not a failure.
Important notice of the SG MODE and SG PATTERN
