HDMI over Ethernet (4K)

I've got it to work by "Direct" connection in/out from the patch panel. So it works. But I'll be going down the IP route as soon as I can. 7 bed 3 Reception rooms in the main house plus more TV's in the games room and then the cinema room but That'l be dedicated equipment when that gets done.
 
I’m using HDBaseT adapters. One sender via a network switch to two receivers upstairs. It works very well but required dedicated cabling.

I tried it over my existing wired network and found that while it worked everything became very slow. I’m assuming it just floods the network with broadcast packets.

HDBaseT is an evolving standard for running HDMI over typical Ethernet Cabling and connections. It is not meant to interoperate with an Ethernet Network. It is meant to use the commodity Plugs, wall plates and Cables that are easy to buy and install, rather than using an entirley new connection scheme. The equipment on your HDBaseT "network" needs to be ALL HDBaseT equipment. Connecting an Ethernet device on a HDBaseT network will cause the HDBaseT components to switch to “Ethernet Fallback Mode" (EFM) , which should do no damage, but will not support HDBaseT signals. The HDBaseT 1.0 spec is based on the "5Play" feature set.

its a HDBaseT specific network switch - yes ?
 
Yes. I use separate switch (and cabling) for the HDBaseT.

The switch I'm using is an old 3Com Gigabit desktop model.

The product description at the time I bought my adapters gave the impression that they'd work over an existing network. It took some digging to find out that they won't.

I've been happy with them for sending from the Sky HD box downstairs. The picture looks perfect on a 32" 1080P TV and only required a single Cat5e cable that was already in place.
 
sorry to hijack thread but it seems old thread and OP solved his problem.

Similar problem but im looking to mix 2 x 4k tv, and 3 1080p tv. I know this is going to probably cause problem with EDID and 1 of the 4k tv is 30 metres away.

I currently have 5 TVs hooked up to the sky q box on mix of 1080p and 720p. Sky q box goes into 1080p hdmi spliiter, 2 TVs get fed by hdmi (one via a 30 metres HDMI 1.4 cable, and 1 TV standard length 1.4 cable - both 1080p) remaining 3 TVs get fed via RF modulator (max 720p) and shared via coax.

I thought above would give me the 4k to both TV, 1 via a 30m cat6 cable. I would like to keep existing setup via 1080p hdmi splitter to RF modulator to feed to other TVs via coax.

So the final puzzle for me is how do I feed both 4k and RF modulator (720p) at same time? if I get a switch like below is it going to be feed 2 x 4k TV at same time or feed 3 x TVs via coax and RF modulator. The switch listed below would go direct into sky q box.

also im looking to do this on the cheap if I can only watch 4k say on the 2 TVs at the same time that is fine (with the 3 others not working). But I need to be able to switch to 1080p on all 5 sets. If need be I can have 2 hdmi cables connected to each set that run 4k/1080p. 1 coming from the HDbaseT, 1 coming from current HDMI 1080p splitter and using the awakelion switch to change between 4k/1080p

can you get some Q minis , for the 3 tv's , with their headphone RCA/analogue convertors ?

The linked Infasctor has no reviews, and a lot cheaper than the 1K setup, i had linked, so I would check out that it will really drive the distance
 
i have 2 spare neet extenders which are brand new in the box somewhere. so could do 2 separate rooms.

they basically send 1080p hdmi signal along an ethernet cable. if you are interested i could always stick a thread up on the members market.
 
Think I've found my alternative to the switch at the top of chain only feeding 1080p or 4k.

Not too bad price wise, some of the scaler "matrixes" were £1000s.

Above would be from sky q box. Hdmi out 1 would then go into :

https://www.amazon.co.uk/Infacter-E...188619&sr=8-3&keywords=infacter+hdmi+extender

and feed the two 4k TV

Hdmi out 2 would then go to my existing 1080p splitter and feed the 1080p/720p TVs.

Unsure if going through a splitter/scaler then getting split again is going to cause problems?
 
...explain why Qmini would not satisfy 1080/720 need ?

scaler'$$$ !, does scaler work with 10bit colour, ... or, later, with hdr ?
... put the money into a more assured/long-term hdbasetT solution.

Qmini would work but as I already have a aerial in each room, wanted to use coax where 720p was only needed. It would also limit me to 3 x minis.

I would be using a hdbasetT solution to feed a 4k TV 30 metres away and 1 4k TV at transmitter source. The receiver would also allow me to add 3rd 4k TV but I'm guessing the cable would be limited 3m from receiver if I wanted 4k.

Scaler seems pretty future proof

Did have a look at just add power,
juts had a look ... maybe their (Chinese?) product is good but the website is confusing

3G ULTRA HD OVER IP PLATFORM (4K)

Build a 4K & Ultra HD matrix using the Third Generation of Just Add Power Transmitters and Receivers. Distribute HDCP 2.2 content to multiple displays HDMI 2.0 or otherwise over a 1Gb network. The built-in scaler on the Receiver allows for seamless display on both 1080p and 4K screens. Mix and match 3G, 3G+AVP, 2GΩ/3G, and 2GΩ/3G+ models to get the exact feature set needed.

Are they referring to 2G/3G mobile network ? that is the signification of that, in Europe
if so, first time I have heard that is robust for delivering a lossless 4K stream. ?

EDIT: ok
1) The 3G products are significantly better than the 2G products when it comes to compression, but it requires significantly more bandwidth (more expensive switches). The original 2G stuff used JPEG2000 compression, I cannot remember off the top of my head what the 3G stuff is using. The 3G stuff is usable in a house, but I wouldn't be using it in a theater or for any critical viewing.
so g=generation , they are compression products

One mini might do it, adjacent to the q box, if you can use its composite+stereo outputs.

maybe sky will adopt HLG, but otherwise if they uise HDR10 the capabilities of the colour space mapping 2020->709 on the scalar could be important ...
but if you don't like it can always send it back ?
