Re: ADV7511 snow noise

Hello Guenter !

I try to turn off the input video until the hdcp is authenticated.

But it also has the snow screen.

Our input is 480p bt656.

I wait a long time to ensure the hdcp is authenticated and the 0xc8[3:0]==4,then I turn on the input bt656.

It appears snow.

When I turn off the hdcp,this operation will not appear snow.

So do you have other way to avoid this problem?

Thanks!
