I have spent quite a few hours looking for a solution to my problem, and I just can't seem to find a solution that isn't insanely expensive.
Currently in my house there is a utility room in my basement with a hub for all the coax/Cat5e runs that I have going to every room in the house. My ultimate goal is to build a HTPC with XBMC, and send the audio/HDvideo from that PC to the different TVs in my house.
Now I am aware of HDMI over Ethernet and some of the products that Monoprice has. This may sound stupid, but from what I understand no use of switches or anything would allow you to use that ethernet run for your Computer Network + HDMI signal. So this effectively would be turning my ethernet runs into long HDMI cables. My issue with this solution is that I really would like to utilize my ethernet runs for computer networking.
So my next thought is to try and send my HD signal over Coax. Wow... not cheap. I found a couple different solutions. The cheapest being Cables to Go 40574 TruLink HDMI over Coax Transmitter and Receiver. Its $282 on Amazon for a Transmitter and Receiver, then an additional $150 for each receiver after that.
From there I came across "Channel Plus 5415HD Single-Channel HD Modulator" And Zeevee. Love the idea, hate the cost. I think the prices are so high on these because they are mostly used commercially .
A solution I would love to see(If it even exists), is something that uses your ethernet network to send your audio and video. Then you buy some device that you plug your ethernet cable into, then it outputs HDMI or Component to the TV. Pretty much VNC without the computer. I have found things that do this wireless, but reviews are not very good and its often limited to one transmitter/receiver.
I guess to explain my overall problem is that I stream 95% of our TV and Movie watching from my server. Currently I have Popcorn Hour A-100 devices on each of the TVs. I want to upgrade them, but I hate the idea that every time I need to upgrade my media streamers, I need to shell out the cash for 5 different devices.
Thanks in advance.
