These are not the most commonly installed devices but they do exist. You may already be familiar with powerline networking equipment which is used to send Ethernet signals over your existing mains electrical wiring which can be used to improve your internet and WIFI connection. These work as a pair in a similar manner with the difference being that instead of connecting a wired internet connection into your powerline adapters you would connect HDMI cables which would connect to your AV equipment and TV at either end. HDMI, or High-Definition Multimedia Interface is the modern replacement for coax in the home. It is used to carry signals between devices with the maximum amount of data possible for high definition or ultra-high-definition broadcasts. It can carry audio too. HDMI was invented by Japanese TV manufacturers to help improve picture quality and works exceptionally well.

For example, if you wanted to extend from the top floor of a building or to another house, you could run the cable through the walls or underground. HDMI over fiber can still be used for shorter extensions if you wanted also. For shorter extensions, HDMI over fiber can be used as a solution also even though it's made for longer extensions.Fiber optic HDMI cables can extend the connection similar to HDMI repeaters. You will only need a fiber optic HDMI cable instead of also needing extra extension devices or cables, which makes using fiber optic HDMI cables a cleaner option.

These cables aren't meant to be used with an extender, repeater, or switch and should be used alone. They also must be installed in the correct direction, with the output/ display label connecting to the side with the display. I’m including the HDMI video extenders plus USB here as they can be very helpful for CCTV systems where the DVR/ NVR and the monitor are in separate locations and you still wish to control the equipment. At the transmitter end a USB can be connected which connects into a port on the DVR/NVR where you would normally connect a mouse to control the unit and at the receiver end beside the TV a USB mouse can be connected which would allow you to control the CCTV equipment as you would normally do but in a separate location.

This is especially helpful for your home automation experience. Most people don’t want to have tons of boxes and cables in front of them when they’re trying to enjoy TV. No one wants to look at a ton of cords around their entertainment area.

When you wish to send HDMI over distance, using a HDMI cable it not the best way of doing things. The better option would be to convert the HDMI signal so that it can be carried on a twisted-pair data cable like a Category 5e or Category 6 cable. These video baluns come as a pair, a transmitter and a receiver, the transmitter connects to your HDMI device (Sky box, game console, Bluray etc,.) with a cable and the receiver connects to your TV with a second HDMI cable with an interconnecting data cable (or two) in between. Coaxial cable was invented sometime in the 19 th century to carry radio signals. It is comprised of a copper core of two layers surrounded by insulation and shielding. The idea was to deliver analog signals with a minimum of interference. The technology was in use until recently, first in radio and telegraphy, then TV and then broadband. It was gradually replaced with fiber or other technologies that offered faster transmission speeds. Even though coax is insulated, the signal needs frequent repeating and is subject to data loss over distance. Coax was popular because it was superior to anything else at the time, was cheap and easy to use. It was also very durable. Fiber is faster and can carry more data at once. Though fiber requires more upfront investment, it requires less maintenance. HDMI
