ADV7842 3D_Comb(TBC=Off) , Output picture has small waving noise issue at CVBS input.

Hello,

When I start 3D_Comb function, Output picture has small waving noise issue at when I used CVBS input.

However, this issue doesn't happen when I used Y/C input.

also, when I stopped 3D_Comb, this issue disappear even I used CVBS input.

System contens

3D_Comb = On

TBC=Off

64Mb SDR

It seems this issue is relating 3D Comb function.

How can I fix this?

Regards,

Bogey

  • Hi Bogey,

    AVES is software that runs on Windows and allows you to read/write registers.

    The software driver (also known as repeater software) runs on the Blackfin processor, uses RS232 for input/output, and configures the ADV7842/ADV7511 to accept a particular input (CVBS, S-Video, VGA, HDMI) and output over HDMI.

    If you have EVAL-ADV7842-7511, this software starts automatically.

    If you have EVAL-ADV7842-7511P, this software can be started by typing "startrep" at the command line.

    Just use RS232 communications program like Teraterm and watch RS232 output after power-up. Make sure AVES software is closed. Only one program can access RS232 port at a time.
