There are two major reasons you’d want to run HDMI signal over Ethernet cable:

1. If you have to run the cable over long distances HDMI cable is not the most reliable. Ethernet cable, Cat 6 specifically, on the other hand, is way superior when it comes to reliably transmitting signal over hundreds of feet. It’s also less expensive.

2. You spend all that money of a glitzy 4K Ultra HD TV set and had it neatly mounted on the wall. But you still had to run the cables from TV to DVR, Blu-ray Player, what have you. All of that equipment is likely staked up in the TV stand/console nearby. It’s got to be a better way.

Absolutely. You can run HDMI audio, 1080p, 2K and 4K video and IR signal for your remote up to 220 feet using only a single Cat6 cable and have all of your video equipment neatly stored somewhere in the basement in an enclosed rack or cabinet. The product is called HDMI Extender or 4K HDBaseT Balun and it the set consists of one transmitter and one receiver – one or both powered by AC adapters. The built-in IR extender in HDBaseT adapter allows IR remote control of source devices from a remote viewing location by sending IR commands received in the vicinity of your TV set back to the source devices. This device is 4K, 2D and 3D compliant and it runs at 340 MHz bandwidth.

There are a few things to note.
