Tv connection: HDMI...
 

[Closed] Tv connection: HDMI to Cat7 and back to HDMI?

Is there an adaptor / converter that will convert an HDMI input cable through a CAT7 cable then back to HDMI?

At home I have the TV (Virgin) box in my front room but have the TV in the rear garden room.

I have a cat7 cable running between the two (perhaps I should have put HDMI or Coax in addition/instead)...

I've seen what I think might work online but not sure if it does- is is as simple as buying a converter box either end ?  Any suggested products?

(the remote works from the other room as its radio not IR)

Help/advice appreciated, thanks

Why don't you just move the box to be next to the TV?

I've used a Mirabox HSV373 HDMI extender before which is probably what you are looking for.  It was 63quid which is really quite cheap for these things but it seemed to work ok.  It's a transmitter receiver pair and you plug hdmi into one of each and then connect them with your network cable (I used cat 5 over 100m and it was fine)

Quality is ok but it's not a super robust solution.  I found you had to plug things in in a particular order to get it going the first time (I think it was network cable, receiver hdmi and then transmitter hdmi).  Once going it was ok

more expensive solutions are available 🙂

Note that it will work over a network as well rather than just a direct connection but I wouldn't as it just splatters data all over the place

That sounds plausible.  HDMI is an encrypted protocol, If the source can't communicate with the destination to establish security then you might well end up in a "computer says no" position.  Think Macrovision on steroids.

Cougar, because the box requires coax input direct from supply from wall, no coax route to rear room

You can get "Mirabox-a-likes" for half that, they even have the (unnecessary, I know) IR repeater.

Dan I think Cougar was suggesting getting Virgin to re position the box, not to simply move it next to the TV yourself.

You could try ringing them and seeing how much a second box would cost - they used to do deals on having a 2nd one?

@aphex,

I should have said I'm trying to avoid building work/running new cables

Or:

Get a streaming box/stick (NowTV, Roku, FireTV, whatever) or an internet-enabled TV (LG, Samsung, whatever) and connect that to the internet over the ethernet.

Then cancel your Virgin TV subscription and get a Netflix/whatever-you-fancy subscription instead?

@oldnpastit.

Yes another option, thing is I've had horrendous experiences with other internet providers (BT of course) and I actually have Virgin mainly for the internet anyway - its expensive but they actually provide a good service in my area and actually answer the phone and provide tech support when rarely needed.....

Does anyone who has streaming only ever get the TV crapping out periodically, stalling etc...  that would annoy me too.

I have one of these

https://www.amazon.co.uk/Neet%C2%AE-EXTENDER-FUNCTION-available-separately-BLACK/dp/B00HFUTTQY

Works well with 1080p signals, requires x2 Cat5 (or upwards)

Nah, I was suggesting extending the cable out.  The OP said, "I have a cat7 cable running between the two (perhaps I should have put HDMI or Coax in addition/instead)…"  So long as it's not been plastered into the wall or something daft, it should be trivial to run an extension lead alongside the existing cable.  Male F-connector at one end, female at the other, screw it into the existing cable termination.  Job jobbed, and a lot more elegant / robust than fannying about converting HDMI into something else that might or might not work downhill with a prevailing wind on alternate Thursdays.

what, like under the floorboads and then built into the lining of the wall behind a nice shiny new run of kitchen units?

errr....

In hindsight Should have put coax in at the same time.....

Hahaha sorry, didn't mean to insinuate anything!  Is it not in trunking or anything?  Bugger.

ha! yeah, will get something sorted.  I think there's also a coax-ethernet-coax solution but more expensive kit.....

TBH, at that point I'd be tempted to try jury-rigging something. You're not converting coax to Ethernet, you're converting coax to twisted pair.  There's no active networking going on, it's just a different wire.  For the price of a couple of F-connectors an Ethernet cable it might at least be worth a punt even if it doesn't work.

I use a splitter with Labgear HDMI 60m  Extender Over Single CAT5/6/7 it was about £70. i use it for sending sky hd to another room. it is great. i used a cheaper one before but used to get interfearence form light switches / central heating thermostat

Here.

Can be had for like a quid each if you're prepared to wait for them to arrive on a slow boat from China.  Just need a M/M coax lead for the TV end and a M/F extension lead if the existing cable won't reach the network socket.

NB I'm assuming the cable you've run is just a cable between the two rooms.  If there's a switch between the ends then this won't work!

Cheers cougar, as you say might as well give it a try if it's only8 a few quid
