Notes when using SG MODE/SG PATTERN
• During factory mode, choose the correct route when changing.
• Basically, during VDEC SG output, make sure to connect SG output's Y or G to the AVI input terminal of VDEC.
• During SG MODE, turn off the blanking 50IRE setup function.
• During VDEC SG output, set the YC seperation setting to NTSC.
• It is possible to use ANALOG OUT MODE together during DIGITAL OUT MODE.
The Main VDEC can output digital color difference, in which colors will appear.
But the route to VDEC input cannot be analysed therefore care should be taken when using.
Depending on the situation, please use the proper analog/digital output.
• The SG MODE outputs color difference and RGB only. Therefore, in the case of CVBS, only the Y input is used resulting in no color.
This is not a damage result nor error.
• The SG MODE's ANA AD RGB (route to input 525i to AD by RGB) as a set's route, the setting does not exist. For this account the
latter part from MVDEC does not have set values, resulting in having funny colors in colorbar, the brightness changes after
switching, etc.
This is not a damage result nor error.
• Depending on MVDEC's part version, ANA_MVDEC_YCBCR may not display colors.
