Extending HDMI Signal over IP or Coax

[brianfarm6767]

First post on the site, but have been coming here for years reading all the great info.

Reason I am posting is we are coming towards the end of building our first home. We have cut the cord and use Apple TV or Roku for all our TV and Streaming. We will have three TVs in the new house (Living Room, Bedroom and Back porch). One issue I have realized is that with things like PPV sporting events that in order for me to watch it in the living room and on the back porch like we could with cable I would have to purchase it on both streaming devices. So i set out to find a work around.

My plan is to have the living room Apple TV feed both the Living room TV along with the back porch tv when we entertain friends over for sporting events. Our house is prewired with coax and Cat5e so those are my options to transmit the signal. I know ideally I could run HDMI, but I want to avoid cutting new holes in my new walls for a little bit at-least. I plan to buy

to split the signal from the Apple TV, then run it to either a HDMI over IP

or HDMI to Coax converter

Concerns I have about the Cat5e option is the strain it would but on my networks bandwidth and could possible make streaming more difficult. The concerns I have with the coax option is that I have no real experience working with coax. Would I need to go into the attic and add a different kind of splitter rather than the one the house would come with which would be designed for an external source such as a satellite being connected?

Any input is greatly appreciated

I think you are assuming that you can use the same CAT 5e that you use for your network to distribute Apple TV to the remote TV. If you look at the diagram they don't show the wires connected to a router, modem or any computers. CAT cable is much thinner than HDMI so it's easier to run new cables (usually CAT6 or better these days). You want converters that are HDBaseT compliant like this one

I have used HDMI over coax and it can be tricky. The one you link to shows cameras and doesn't mention HDCP which you have to have for normal content. You need RG6 and splits and the quality of the terminations can affect whether it works.
If you can run a real HDMI cable it would be the best solution. A good installer may be able to do it without messing up the walls.
