For a modest home theater system, the HDMI ports on the back of your home theater receiver act as a matrix switch. They allow you to plug in several HDMI sources and output each source to your display (TV or projector).

HDBaseT matrix switchers use category cables to send the audio and video signals long distances via baluns/receivers, with limitations typically to 328 feet.
