ADV7181C - RGB to 422 EAV/SAV

Hello,

Right now we are testing the ADV7181C on the EVAL-ADV7181CEBZ board. For that we are using the ADV Register Control program (Version 3.56) and the sample script version 3.2c.

Unfortunately the sample script does not offer the option RGB (as input) and 422 EAV/SAV (as output) using the color space converter.

Is there maybe a new version for the sample script that offers that? Or are there other resources we can use to test that?

Thanks.

Sincerly

    Hi Peter,

    Is your input in graphics mode then?  You would essentially take the input piece from a script that has your input format.  Then you need to program the CSC for the conversion-- unfortunately it's referenced in the manual that there is a section with examples but no such section exists.  I'll see if I can get something posted up here though.

    After that you just need to set up the Pixel Port output bus to whatever YCbCr format you want-- and take that piece from a script that has the same output as you want.

    Programming the CSC is not a straight forward task it would be best if you can use a sample script to start with. Can you define what exactly your input and output requirements ? Hopefully we will be able to supply you with something 'premade'.

  • Hello DaveD and VDPRx,

    Thank you for your input on our problem.

    We would like to test the following:

    IN: RGB XGA 1024x768 @ 60Hz with ext. hsync and vsync

    OUT: YCbCr 16bit 422 EAV/SAV

    Please let me know, if you need anything else.

    Peter

  • Hi Peter,

    Unfortunately, there is no script available to configure the EVAL-ADV7181CEBZ board for a RGB XGA @60Hz input, with the ADV7181C configured to output YCbCr 16bit 422 EAV/SAV. The encoder will not support such an XGA @60Hz type of resolution, and only 12 output bits from the ADV7181C are connected to HDMI transmitter.

  • Hello,

    In addition to the ADV7181C-evalboard

      we have prototypes of our own design with the ADV7181C as well.

    So we can use these to test the desired mode.

    Any help and input on finding register settings to test XGA-in and YCbCr-out

      on our prototypes is greatly appreciated.

    Thanks,

    Peter

    --- desired mode ----------------

    IN: RGB XGA 1024x768 @ 60Hz with ext. hsync and vsync

    OUT: YCbCr 16bit 422 EAV/SAV
