I have a Raspberry Pi running a slideshow. I would like it to display on the TV when the cable box is off, but show the cable box when it's putting out an HDMI signal.

Is there a way to do this? For example, an HDMI switch that will prioritize one input?

Or maybe a TV that will always show input on HDMI1 if there is a signal? And if no signal on HDMI1 then show HDMI2?
