A:Answer This means you can connect you Blu Ray player, Satellite, or Game console to the receiver via HDMI and the receiver channels the same resolution video signal back out and into the TV. You'll notice on the back of the receiver there are multiple HDMI inputs for devices and 1 HDMI output for the TV. It's meant to streamline your device sound options. So essentially, The video signal is "Passing Through" the receiver to the TV. Hope that helps.
