hello, I have several questions about the usage of ADV7611,

 

      As mentioned  in datasheet UG-180,if CP CSC is configured in automatic mode,we have to program register INP_COLOR_SPACE to a proper value.

      my first question is if we program INP_COLOR_SPACE as default value (0b1111,as mentioned in UG-180,input color space base on the primary mode and video standard settings) and left PRIM_MODE && VID_STD to default value again ,what will happen?

     and the second question is:

      if input video resolution changes, for example change from 1080p to 720p ,then do we need to update PRIM_MODE && VID_STD values to match receive video ?Is there an auto mode of these two registers?

 

    Thanks!
