SO, i have a similar situation to a lot of people. I moved in to a new home about a year ago and have rg6 coax ran to every room in the house. I have Directv and have a piggyback feed of one of my receivers to the rest of the house, however the quality is fairly poor. I want to see if there is any way to get HD to at least 1 other room. My tv is 2 floors away and running new cable, hdmi or component, is out of the question. I have researched this for a while now. I have seen products that can produce an HD feed over coax, but are mostly for businesses and cost WAY too much. I have seen a few cheaper devices and wondered if anyone could offer any advice as to whether either of them would work in combination with one another.
My first idea is HDMI to CAT6 ethernet. While I cannot run an ethernet 2 floors up I wondered about a powerline adapter. So basically hdmi-ethernet-powerline and back again. I feel this would never work, but in theory it might, probably very poor quality with all the interference im bound to get.
My 2nd idea is using my existing coax. So basically HDMI to ethernet, and ethernet through my existing coax. Ive seen devices (MoCA adapter) that can transfer high speed data over rg6 coax. So, hdmi to ethernet adapter to MoCA adapter and back again. I know this all sounds ridiculous. But im not paying $600 dollars or tons more to get hd on another tv with some other devices ive seen. I also dont want to dish out the initial cost and $10 a month fee for another receiver.
Im basically starting this thread so someone smarter than me can tell me there is some sort of non-compliance issue or technical concern as to why either of these ideas will never work.
I am open to any input or suggestions but please dont suggest any "solutions" that going to cost hundreds or thousands. Because I know there are HD rf modulators that would do the trick.
I know there are threads very close to this one however I think mine is unique. Please help, this whole situation has been racking my brain for over a year now. Any input is appreciated. Thanks!
