Anyone playing with a HDMI over IP setup?

Looking for a way to share devices between 2 rooms but can't put a cable in so was wondering if HDMI over IP (not extenders) would work over a decent powerline connection?

I've seen units with powerline built in so that suggests the bandwidth provided is a possibility and Sky can do it over wireless now with Sky Q so is there anything that captures and compresses to be sent over an existing active network (internet basically)?

Would mainly be for media pc and PS4
 
I used to use HDMI extenders over CAT6 for my SkyQ main box to my bedroom. But I ran a dedicated CAT6 cable from one end to the other. I do have a faceplate on one end though, and that was tricky enough to get working properly. Very occasionally still get a "snow-like" effect. Since getting rid of SkyQ, I now have a Now TV box set-up with it. I couldn't use Xbox One over it, as the controller dropped connection at that distance.

I would say that powerline networking doesn't have the bandwidth for full uncompressed HD. I have the TP Link AC1200 powerling things, among the fastest you can buy, and they don't really have the bandwidth. My connections max out around 6-8 MBPS when transferring files between computers, or downloading straight through there powerline network. It works OK for Plex and stuff, with lower bitrates, but for proper HD, it's just not fast enough (Proper HD can have bitrates of up to 40MBPS). I am currently planning to hardwire the whole house with CAT6 and ditch the powerlines anyway. Mine are notoriously unreliable. They need rebooted several times a week, on average. And I'm on my 4th set now. They have all been the same.

I am quite a heavy user though. My server sits in my cinema room, which is nowhere near my router, so I use the powerline to my server almost constantly. I am forever passing data through the powerline network to that particular point. Whether that be downloading / uploading from the server, or streaming media throughout the house / remotely with plex. That specific powerline adaptor does take a kicking. It is a 3 post one though. And I don't, admittedly, have any problems with the single port ones I also have. But my other 3 port does need reset more frequently than the rest too. So I think there is more of a problem with the 3 port models.
 
To save any headache I'd run cable and be done with it. I use HDMI to ethernet adaptors at work and have barely had any issue with them for years. 2 of them, device > LAN > Projector, in use several times a day, 5-6 days a week. They're powered 24/7 too, can't remember the brand though.

My experience of powerline networking over the years at home has been that it works fine for most stuff but isn't suitable for true HD streaming and can be frustratingly slow for backups/file transfers etc. And occasionally needs rebooting...
 
I've done the HDMI to Ethernet, but not through Powerline. The splitter was combined with the converter and I got converter and cable all in for about £50.

The infrared remote works perfect too and we get a fantastic picture on the upstairs TV.
 
Easiest and best option I agree is to run a cable but I can't, no way around that.

The standard HDMI to Ethernet adaptors won't work as they only use the physical attributes of the cable, I need to convert the video to a data stream sent over the existing network.

Ideally I need something that takes a HDMI in, captures it and sends it over the network compressed. This is what Sky Q does, Nvidia gamestreaming and the PS4 can do remoteplay but it doesn't work on the media apps. I've got lucky with the powerline adaptors and get a good connection (about 33MB/s), not great but Nvidia gamestreaming only needs a max of 20MB/s so in theory it should be enough.

Could the media PC capture it and send? Or would that just add a massive delay.
 
Sky Q directly streams the data packets received via satellite over IP without any additional processing other than decryption. A typical HD channel only needs 10-20Mbps at peak which a good enough wireless signal can cope with.

One option is to take the HDMI output from the box, feed it into a HDMI capture card and use something like ffmpeg to encode and transfer it via IPTV. You can then use whatever device you like as long as it can decode the stream at the selected bitrate.

TL-PA9020P is faster, it’s 2000Mbps and works perfectly fine for 1080p HD but won’t be able to do 4K. You don’t need to plug them into your router either if you just want to send the video signal as that’s what I do. I use them alongside a hdmi extender for Sky q and ps4 / Nintendo switch and works perfect.

Completely forgot about your thread, I even posted in it :o They still working well for you then, no issues with lip sync?

Currently using the powerline adaptors to connect the other room to the broadband router so would need everything going over the same connection and it does look like the current devices flood the network. A friend says he's had success with a wireless HDMI sender so going to borrow that and see how it performs.
 
I tried my HDbitT senders over my normal network and everything else on the network did gradually grind to a halt.

Over a dedicated Cat5e connection the picture (1080i from a Sky HD box) is perfect. With my senders the audio does gradually go out of sync and they need an occasional power cycle to fix it.
 
You aren’t meant to route the signal through a switch. Forgive me, but why would an end to end HDbaseT connection cause issues with network traffic?

Yeah they work with no issues at all. No delay, haven’t had any lip sync issues and takes about 2 seconds to appear on screen once I turn whatever device I’m using.

I have had it running connected to the router a few times and it didn’t cause any network flooding issues, but if you are really worried then just create a seperate vlan for the port you will use it on.
 
The general advice with video/audio over IP is to keep it away from regular network traffic as the two don't get on well together.

In practise then, that means you could use PowerLine once the AV signal is IP-ised, but you shouldn't have internet access over the same connection.

Companies such as Netstreams have a complete solution including approved network switches, but again the whole network sits isolated from the data traffic for internet and general PC use.

Yeah, that is what I am doing Lucid :)

I'm only running the video over the powerline adapters, it's not connected to my router, so no internet traffic hits it at all. If anyone did need to have internet traffic running through however, then I would just segment it with a separate vlan.

I've been told the new above extender can carry Dolby Digital 5.1 and also do 4k @ 60hz. I've asked to trial the product, as will be interesting to see if it can do what it says, but will report back once I've tested. The person I spoke to said that as long as it's going over a 1gb network, then the above will all be fine. Fingers crossed, as my adapters are saying they are connected to each other at 994mb which will be fast enough. I'm not too sure what compression method it will be using, just waiting to hear back on that, but guessing it will be something like JPEG2000.

Apologies for pulling up an old post.

I would like to find out if the following setup would work with SkyQ please:



Current setup:
  • SkyHD
  • Magic Eye (Coax cable)
  • TV in living room & TV in bedroom (35 meter distance between both)

Desired setup:
  • SkyQ
  • HDMI over IP
  • TV in living room, TV in bedroom, TV in guest room (35 meters and 20 meters distance from the living room)
  • These will be direct Cat-6 connections (i.e. not using powerline connectors)

Questions:
  1. Would this work with SkyQ?
  2. Do you think the provided IR Receivers and Blasters would work with SkyQ?
  3. Simmz, did you ever get to trial the http://www.scion-tech.co.uk/sc01_1108_hdmi_over_cat5.html? If so, how was it and would it be a better solution?

The alternative is he stays with SkyHD and his current setup.


Thank you advance!

JC

Not that it really matters, but the HDMI extender you've selected doesn't appear to be HDMI over IP. It is HDMI over Ethernet which isn't quite the same thing. HDMI over IP senders aren't going to limited to 40m.

I found that the IR senders on my set of extenders (different make and model) were very laggy and unreliable. We now control the Sky box using their iOS app which works much better.

Your diagram appears to show how they supposed to be used.

Thank you for your reply.

Yes, apologies, that's my naivety on this subject showing. HDMI over Ethernet sounds more accurate.

You're right, the diagram is the same as theirs and probably adds no further value other than showing the distances. It also helped me in better understanding how it all would go together as I drew it.

"I found that the IR senders on my set of extenders (different make and model) were very laggy and unreliable", aww fiddle sticks! Well that ends this device as a possible solution, although there must be something that works well?

Due to the circumstances, my father is eligible for a Sky accessibility remote. The 'plan' is to set this up for him as he is disabled, lives on his own and so is the only one who watches Sky - it would simply make life a little easier for him while keeping costs down (i.e. not having to pay the Sky Mini box multi room £12 a month subscription).

http://www.scion-tech.co.uk/sc01_1108_hdmi_over_cat5.html looks a cracking device, but I would be interested to know any feedback on it. Or, an alternative device someone might recommend that fits the bill?

Thanks again for the reply.

The 'different make and model' is the important thing here. The extender you've linked might work perfectly. If it doesn't you'd be able to return it for a refund.

Unfortunately, it's a chicken and egg scenario.

To test it, I would need to order a SkyQ box for him first.

If it doesn't work though, then I would be better off sticking with his current SkyHD & magic eye.
