ADV7611 Interlace Video Capturing

Hi All,

I am trying to capture interlace HDMI formats from the ADV7611 Encoder via 16-bit parallel bus. I was successfully able to capture 1080p and 720p video formats through IMX6Q application processor, but have no luck in capturing 1080i and some other interlace formats. I am using following i2c settings in encoder driver :

 

[Bash] ADV7611 settings - Pastebin.com 

 

The attached image shows the capturing of 1080i input.  As shown, captured frames moving very fast vertically for 1080i input. So what else should be in my checklist to get this work from ADV7611 side ? I wonder whether my EDID data set is applicable for the input specifications. 

 

Thanks in Advance

Anuradha
