To implement high definition video distribution, you will need amplifiers to boost your signal over longer distances. You will also need various splitters to split the signal into multiple outputs. HDMI Switchers will be needed if multiple sources are being accessed. The longer cable runs also cause noise to be picked along the cables. “Baluns” convert signals at each end to cancel out signal noise picked up. “Matrix” switchers and extenders provide advanced signal routing capabilities.
Some equipment provides Infrared (IR) routing functions which allow the use of remote controls via the system without needing the cable box in the same room.
