There are plenty of wireless and IP HDMI options on aliexpress, the ones I have tried from best to worst were:

a 60GHz one - really nice, but will not go thru anything at all. With the transmitter behind the PC, I would be lucky to get 2 metres distance. Thru a doorway and down a hall its perfect - till the door is closed and it stops.

I tried a "5G" one that uses wifi between the 2 boxes. Cant choose a channel, and it just broadcasts its stuff and annialates anything else in that part of the band. Appears to use 40MHz in the lower group of channels. It compresses the image heavily, little bit of lag - no good for gaming or using a mouse, but its not unbareable to use a remote control.

3rd lot was HDMI over IP - that's the first lot I got. Terrible.

Compresses it even more than the wifi one. Sends it as broadcast over the lan. You can connect to it and change its IP addresses but that doesn't achieve anything. Even trying to put it on its own VLAN and it would take the network down. I blame the unifi switches for not coping with the broadcast storm for that one. Needs a dedicated cable or a dumb switch and nothing else you care about connected to the network.

Also it appears to always output 1080p60 from the receiver despite what was put into it, making for massive dropped and duplicated frames juddering. I only ever tried it with stereo audio, and it worked but I think it was processing it somehow as there was frequent clicks in the audio. A windows desktop is unreadable over it despite putting 1080 in, and getting 1080 out. Seems to use some very heavy jpeg compression as it was not cleaning up with no movement. video content was tollerable for things in the background but you wouldnt be watching a movie over it. Lag on par with the wireless one.

Gave up and got a non compressed needs its dedicated cable option and ran another piece of cat6 - it periodically drops out and resyncs with the display, and because its on a splitter it sometimes makes all the displays on that splitter drop out momentarily while it does its handshake thing.

For the next lot of stuff I repurposed coax cable for 3GSDI adapters - they work fine for video stuff but mangle anything you give it thats RGB into component and compress it to limited range, so PC use is ugly. Its sending the output of CCTV NVR's around the house to look at on other TVs with some BNC to F adapters, and replacing the F connector RF splitter with an active one made for 3GSDI - minimal dropouts usually with powering on noisy equipement and it may be on the HDMI side of things not the SDI side.

I would have thought HDMI over Ethernet and IP would be the most stable and reliable solution compared to doing it wirelessly. I was looking into doing this last year but it seemed very hit and miss from the reviews, and was wanting to do it with 4k rather the 1080.

I have never used Sky Go. Can I watch programs recorded on my MY Sky box?

I am sure there are better ones that actually use their IP addresses and unicast IP to the other device, but it seems that the cheap ones all go for the no effort to set up route of just spamming the network. It was the frame rate thing that made it useless for the situation because it made anything moving like sports into a juddering mess.

Commercial grade HDMI over IP is replacing HDMI cable runs / HDBaseT for the likes of sports bars where they run multiple displays off multiple Sky boxes etc.

Heck, it's how the commentators watch feeds at a central location for events like the Olympics / Commonwealth games etc.

However, the cheap products you find on-line aren't these products and will cause you a headache.

For a single point to point run in a domestic home, a HDMI over IP commercial solution would not make financial sense IMHO.

No you can't, but it does offer on demand content. Not sure if it will cover all the shows you wish to watch though.

I also think it's pretty unanimously agreed that the quality of Sky Go is very good, so it is definitely worth looking into.

How easy would it be to run a CAT6 Ethernet cable from TV to bedroom? I.E. is there good roof space access and is this a standalone home? The retirement village may have some flexiblity for this kind of work, or maybe you can get away with doing it anway?? What area is this in?

The village is in Napier and is the middle unit in a block of 3. Although there is some flexibility, i.e. we can hang pictures, we can't get a cable (of any sort) from the lounge to the bedroom as the cables would have do be run down the wall i.e. visible cables.

There is already an ethernet port in the bedroom, which I was going to use for internet for the Smart TV.

I am looking to be able to get recorded content from the lounge My Sky box to the bedroom TV and from the responses so far posted, Sky Go won’t allow recordings to be watched and an HDMI commercial solution doesn’t make financial sense in a domestic situation.

Wireless HDMI seems to be the only solution, but may not be reliable.

OK, so no ceiling space so that the exiting cables could be pulled up and then pull back down a second cable?

Unfortunately, no.

I am familiar with the process as I installed ethernet ports in every room in the house we just sold.

It would only be 1 or 2 cables, could probably be routed nicely down the back of some cornice then dropped down inside the wall with bell-hanger bits. I can understand the Village's initial reluctance but perhaps if your willing to use their approved trades along with stumping up not just the cost of installation but paying upfront a bond for reinstatement they might be more receptive?

Jase2985:

why not just use skygo in the bedroom and the regular decoder in the lounge? you are already entitled to it being a sky customer with a decoder

if that doesnt do the trick then look at the other options

Or get rid of Satellite Sky altogether and use an Apple TV (or similar) in each room, running Sky Sports Now and apps for whatever other services you want (Netflix, TVNZ, Three Now, etc).

When we renovated a couple of years ago, we ripped out the dish, aerial, coax wiring etc, and now do everything via internet. I know lots of people who spent time and effort getting Sky decoder etc set up and then had sport they really wanted to see, move to Spark Sport. I reckon in this day and age, you want an internet-based solution that covers your bases for the widest range of possible providers.

Just an update to let you know what I ended up with

We have moved into our new villa in the retirement village and we bought a new TV from Harvey Norman (on special) for the bedroom.
Harvey Norman appears to use different people to deliver different products. If you buy a washing machine, the person delivering has the knowledge to connect it.
The person delivering the TV was an Arial Installer, so I put my problem to him. His instant response was "you need an HDMI Cat 6 extender." So I researched this and bought one from Jaycar (Digitech AC1785).

Yes, it uses the home ethernet cabling, but has nothing to do with Internet Protocol.

It comes with two very small interfaces - a transmitter and a receiver and it even works with the HDMI Splitter I previously used.

In the lounge, the Sky box HDMI output goes to the splitter. One splitter output goes to the lounge TV. The other splitter output goes to the Digitech transmitter which needs a separate power supply (provided).
I then used a Cat 6 patch cable and plugged one end into the Digitech transmitter and the other end into the ethernet socket in the wall.
The villa has a small patch panel in the garage and I used a patch cable to connect the other end of the lounge ethernet cabling to the bedroom cabling. Note that this is just straight trough cabling and it bypasses the router/internet entirely.

In the bedroom I connected the Digitech receiver to the ethernet wall socket with another Cat 6 patch cable and connected the TV to the receiver with and HDMI cable. A separate power supply is not needed here as it uses PoC (Power over Cable - same as PoE).

And that is it. Perfect reception from the Sky box, whether it is live or recorded content.

However, fortuitously, the model I bought had an IR extender.
Two plug-in cables are provided. One plugs into the Digitech receiver in the bedroom and the other end gets stuck to the frame of the TV (or anywhere else that will be in line of sight of the Sky remote control). This receives any signal from the remote control.
The other one plugs into the Digitech transmitter in the lounge and the other end gets stuck over the IR of the Sky box.

Now I can watch Sky in the bedroom and use all the facilities of the remote control.

https://www.jaycar.co.nz/70m-hdmi-extender-over-single-cat6-with-infrared-40m-4k-or-70m-1080p/p/AC1785

Using this Cat6 extender however, you can achieve up to 70m transmission distance while still supporting up to 1080p 60Hz signals! or 40m transmission distance while still supporting up to 4K 30Hz signals! The receiver uses Power-Over-Cable (PoC) technology so it receives its power from the transmitter using the Cat5e/Cat6 cable. The transmitter module even includes HDMI pass-through, so you can connect the original source and still view the display while transmitting. Full audio support is included, with up to 7.1 surround sound. What’s more is the infrared extension too, so you can take your remote control with you and still control the remote device. Includes infrared emitter, infrared receiver and mains power adaptor.

Features:

. 40m(4K @ 30Hz), 70m (1080p @ 60Hz) Transmission Range

. Power Over Cat6 Cable (PoC)

. HDMI Pass-Through

. HDCP & 3D Support
