Connect Android TV box to Atem production studio

I am trying to setup an Android TV box as input for an Atem Production studio 4K. The other camera’s are 720p50, but when I set the Android box to that resolution, I don’t see anything on that input channel. Any tips about settings that I might have overlooked?

Looks like the box does not output 720P50 then. You can check this to plug it into a HDMI of a tv and see what resolution the TV reports.

Also it could very well be that the Android box has a HDCP encryption on. Because normally these boxes display content that may not be copied. The Atem is not allowed to run HDCP content so it will stay black.

TV's may display HDCP content as they are an End device. (There is no posibility to output the signal again. )
