HDBaseT is the new kid on the block. Its primary use case is HD video distribution over longer distances -- but may soon be the standard connector between set-top box & TV (the TV could power the set-top box via the Cat5e/6 cable or vice versa). HDBaseT leverages HDMI & other common hardware stacks, encoding them all into a PAM signal. If fully embraced, we may soon see a single-board computer, monitor & control surfaces all connected via Cat5e/6 cables & powered by a single PoE wall wort. A single-board computer sporting HDBaseT should ideally support daisy-chaining via two RJ45 jacks.
