Cannot decode some standards with ADV7441A

Dear Sr.,

 

We are working with EVAL-ATV-OPxZ Rev.E evaluation kit of boards and we are facing some problems with settings in the scripts (we are using VER.MB3.0 version).

 

For example, when we try to decode CVBS video (PAL or NTSC) into RGB 24-bit 4:4:4, the output seems to have a color deviation (HDMI output in the script provided by Analog Devices). We have measured the output bus (with a ramp video signal at the CVBS input) and we don't see what we expect, so it seems that ADV7441A is not working as we want. Could you check the scripts or tell me what are we doing wrong?

 

Other question is, if we want to get 30-bit instead of 24, we have to set OF_SEL to 0100, is that correct?

 

Many thanks in advance,

Oriol
