I have the EVAL-ADV7612-7511p video evaluation board .I'm using 7612 to receive HDMI inputs from camera(720p @60) , and then feed to 7511 to output the video to the screen.
camera -> 7612 --> 7511 --> screen
When adv7612 output 4:4:4 8bit ycrcb,i can see correct image on the screen,
But when i configure it to 4:2:2,the color is incorrect.
i change two registers:
1)ADV7612: 0x98 03 OP_FORMAT_SEL[7:0]
2)ADV7511: 0x72 15
if there are any other registers i should configure?

Note: The Y1Y0 bits (0x55[6:5]), which tell the sink whether YCbCr 4:2:2,4:4:4 or RGB are sent. Refer Page60 in ADV7511W programming guide. The ADV7511W can up-convert from 4:2:2 format to 4:4:4 format as well as down-convert from 4:4:4 to 4:2:2. To convert from 4:4:4 to 4:2:2, the video data always goes through a filter first to remove any artificial down-sampling noise. The ADV7511W accepts video data from as few as eight pins (YCbCr 4:2:2 with 2x pixel clock) or as many as 24 pins (RGB 4:4:4 or YCbCr 4:4:4). In addition it accepts HSYNC,VSYNC and DE (Data Enable). Refer Page26 in ADV7511W programming guide.
The ADV7511 and ADV7511W are the same die, just different pin outs. The software should be the same except the ADV7511W has a reduced set of options that will work.
I've solved the problem.
Thanks a lot.
