Hi,

 

As the topic title suggests I am wanting to send Sky around the house over HDMI.  I wanted to use a product that doesnt cost the earth, but equally I need it to work and be reliable.  I am considering the LKV383PRO running on its own network. The plan is to have the box in the network rack and have receivers at each TV.  The reason this one appealed is that it is easy to add more receivers to the network.

Has anyone used this specific model before?  I have seen the previous topic, same brand but different line.

 

PBtech sells locally but pretty cost prohibitive, so am looking at Amazon or Alibaba

 

With 3 receivers we are looking at $325+ shipping.  Any thoughts on this or another product that worked well for you?

 

 

 

Cheers

Do you have cabling to allow for simply sending HDMI over the cat5e/cat6 cable? This is a lot cheaper.

I've talked to a lot of people who install cheap HDMI products that transmit over category cable.

 

All but those who are terminally hopeless have learned their lesson with cheap products falling over on them.

 

The cheapies are still popular amongst the electricians who wire houses and then disappear - just in case something ever goes wrong.

I used a cheaie HDMI over ethernet thing, it had 100 megabit interfaces and was pushing about 60 megabit of data out (looking at switch port figures so could be totally wrong like when I looked at what the playstation was streaming). Looked bad. Really bad. Mosquito noise around any text edges, only seemed to support 422 colour so useless on a PC for that too, and there were plenty of dropped frames and things where it would only get the top half of a frame and the bottom part would be held over from the one before it.

 

Output was always at 60p, even when it had 50p going into it.

 

Perhaps if you were just using it to watch something that already looked crap on the other screens it would be ok, but I found it way to unacceptable. It was similar to the junky wireless HDMI I tried for lack of quality.

 

It did seem to not put HDCP on the ouput even when giving an input with it, so it had that going for it.

Big difference between the HDMI over CAT5/6 boxes and the HDMI over ethernet ones. The ethernet ones encode it as jpeg images and stream it as IP data, so will go thru switches etc, and apparently (never tried it) will enable multicast if you have more than one reciever box on the network so you can do a one to many with it only carrying a single stream of data on the network.

 

Basic HDMI over cat cable boxes just send the data as is at their many gigabits data rate, which is why they have shorter lengths they will go on the same cables compared to ethernet. Those have no lag, no processing etc, just have issues on if the edid negotiates properly and what the max data rate on them is. Some will strip HDCP, others pass it all thru as-is to the other end.

That's only an extender to run HDMI over cable - it is not an IP adapter to convert HDMI to IP to run it over network infrastructure as the OP wanted.

 

Extenders like yours work well these days, but if you want IP distribution you need to pay a lot more for it.

Anyone got suggestions for a good Sky distribution system including IR for up 5-6 TVs over CAT6 cabling. Either HDMI extender / matrix setup or IP. Budget $1500-2000 ish.

I am about to lay the cat6 cabling, so yes it would be for the TV's only.  I thought the gear I was suggesting worked like that.  The plan was to run a separate non internet based LAN.  Open to any and all suggestions to get this working well.  If I am being cheap and the quality is bad then definitely happy to listen to better ideas.  Only requirement is to get sky going from server location to 3 tv's over cat6

Get the ones that are not ethernet based and you will be fine, either 3 pairs of the cheapes and a HDMI splitter at the source or else spend a little more on a multiple output sender end. You can go getting matrix switching and stuff if you will end up with other sources there that you want.

 

The standard for HDMI over cat cables is HD base T - but there are many other propriatary ones done by various manufacturers.

 

Just do not get the ones that use 2 cables - they tend to not really buffer and amplify the control signals and some even just dump the HDMI signals straight onto the cat 6 cable without any processing. The single cable ones are so much more reliable.

There are two ways to distribute HDMI signals -

 

The first is to simply have an adapter at each end which allows you to run a HDMI link over cat5e/cat6 cable in a point to point configuration. You need to have one adapter at each end.

 

The second approach is for the master device to encode the stream allowing it to be broadcast over a local LAN allowing point to multipoint.

 

These days if you have modern TV's neither are the approach I'd take. With many TV's now supporting apps or IPTV capabilities I'd simply encode the HDMI stream at source onto my LAN allowing it to be watched from any TV either via an app or UDP/IPTV streaming if it supports it, or a standalone device such as a Pi

The LKV383 units introduce a delay in the signal. You can make an offer on mine (two tx/rx pairs, one of which has never been unboxed). The delay made them unsuitable for my application (feeding a projector at a church).

Looks like with the advice this is the way I will be headed.  Do you know if the IR works with Sky? Cheers

I've given this some thought, trialling one of these https://www.matchmaster.co.nz/amplifiers-and-modulators/10mm-mt47/ I think distributing over coax is the right solution, at least for me. But the mt47 doesn’t produce a satisfactory result.  I will next be looking at something like this https://www.amazon.co.uk/Edision-HDMI-Modulator-Full-Distribution/dp/B00KBXKJ2A  I'm distributing the COAX with one of these which https://www.matchmaster.co.nz/amplifiers-and-modulators/30mm-dda28/ allows for a backfeed from the mt47.  This works great.

 

Edit changed a link to Amazon
