Hi,

     I would like to mention our requirement is that, the 480p resolution video from the HDMI source  should be converted into 8-bit 4:2:2 YUV data with 480p(720x480)  resolution.We are configuring 8-Bit SDR ITU-R BT.656 Mode 0 as  OP_FORMAT_SEL[7:0] in ADV7611. the corresponding VID_STD[5:0] is 001010.We taking the output to 8-bit single channel  4:2:2.

 

The input source which we taken as HDMI player and the output of the ADV7611 will be go to our processor through p7 connector of EVAL-ADV7611EB2Z(Evaluation Board).

 

When we tried with the V4L2 standard applications, we getting the output,but improper with colours and SYNC. The same setup of our driver is tested with the camera and we got the proper output.

 

Please let me know how I can fix this problem? From the driver part, everything is fine and tested.

 

I would like to enclose the register settings which we used for our requirement also.
