In this article I describe what I do to split and extend my video signals.
Video Splitter:
For starters, I use multiple 16-port HDMI splitters to split signals:.
HDMI to Cat6 Baluns:
I send the video signals using HDMI to Cat6 video sender/receiver units. These devices are able to mux in the infrared signals to allow for remote control of devices. These devices take an HDMI signal and convert it so it can be carried by a Cat6 cable. You then reconvert at the other end from a Cat6 cable back to an HDMI signal. Each unit requires power to operate. Depending on the unit, they cost around $30-$90 and can send the signal 60-90 meters.
Stabilizing Video Signals on Long Runs":
I noticed that the video signal coming from the video switcher tends to drop in/out on some long runs. What I found works as a 'workaround' is to simply have a local device attached to the switcher - in my case I have a troubleshooting tv mounted in my wiring closet attached to a small HDMI switch that tends to stabilize all the signals from the large HDMI splitter. If you notice that your signals is dropping, you can try this method to 'stabilize' your signals.
Terminating the Cat6:
To terminate the Cat6 cables, I simply follow the T568B standard for both ends - whether the RJ45 plug or receptacle end.
Here is a custom weatherproof box that I made so that I can plug in a TV in the backyard. I simply added a keystone RJ45 and audio keystone to pass the video and sound signals:
