How to enable to convert cvbs input to HDMI output with ADV7181D demo board.

That's correct. The released scripts for the EVAL-ADV7181DEBZ only have HDMI on the following scripts:

* :525I YPrPb In 12Bit RGB DDR HS/VS HDMI:

* :625I YPrPb In 12Bit RGB DDR HS/VS HDMI:

* :525p/60Hz YPrPb In 12Bit 444 RGB HS/VS HDMI:

* :720p/60Hz YPrPb In 12Bit 444 RGB HS/VS HDMI:

* :1080i/60Hz YPrPb In 12Bit 444 RGB HS/VS HDMI:

* :640x480 _@ 60  Autodetecting sync source  25.175MHz Out through HDMI:

* :640x480 _@ 72 Autodetecting sync source  31.5MHz Out through HDMI:

* :640x480 _@ 75  Autodetecting sync source  31.5MHz Out through HDMI:

* :RGB 800x600 _@ 56 36MHz Out through HDMI:

* :RGB 800x600 _@ 60 40.000MHz Out through HDMI:

* :RGB 800x600 _@ 72 50.000MHz  Out through HDMI:

* :RGB 800x600 _@ 75 49.500MHz  Out through HDMI:

* :RGB  1024x768 _@ 60Hz 12-Bit DDR 65.000MHz Out through HDMI:

* :RGB  1024x768 _@ 70Hz 12-bit DDR 75.000MHz Out through HDMI:

      The question is i want to realize the function of cvbs PAL input and HDMI output with the ADV7181D demo board.

i tried to modify one of the items in the script file ADV7181D_ADV7181D@_ADV7341-VER.1.0c as following，but it don't realize,can you give a right register configuration for cvbs PAL input and HDMI output.

We don't support CVBS to HDMI on the EVAL-ADV7181DEBZ.

If you are interested in CVBS to HDMI, we recommend you look at the ADV7842 evaluation board (EVAL-ADV7842-7511) or the ADV7850 evaluation board (EVAL-ADV7850EBZ).
