Hi

7282.png

AD_RESULT[2:0] is always 000 whenever the video source is PAL or NTSC, bu IN_LOCK is right.  The IN_LOCK is 0 when vedio source is not connected, and IN_LOCK is 1 when vedio source is connected.


I checked 0x02(Video Selection 2 ) is 0x04, and 0x07(Autodetect enable ) is 0x7f.

How to enable video source autodetect ?

 

Thanks !
