ADV7188 Decoder - NTSC Line Length problem

Hi

We are using the ADV7188 Decoder in our video card

Lately we have changed the camera type.

We noticed the video picture turned to be a bad picture: wrong colors, wrong brightness, flickers , etc.

We have read the Decoder Status registers (0x10, 12 , 13) and noticed the only change between the regular good camera and the new "bad" camera

is that bit LL_NSTD is now set.

We are trying to figure out with the camera supplier (SONY)  if there is a way to correct this issue , but since we don't expect a fast answer from them,

I would like to ask if you can instruct us of a way to match the decoder initialization with the current camera state so the picture will be good again.

Issue is that if we are using a different video card we do get a good camera, so we understand the ADV7188 is not flexible for Line Length problems.

Can you help us to make it so?

 

Thanks

Amnon
