Have anybody advice on HDMI Video Senders, had a Philips Scart which worked great, but new TV's have no scart.
I want to control my motorised system in the "mancabin"which is approx 30 meters from the nearest house tv across an open yard.
thanks

Terryl: Thanks for the info had also checked that link, but at £280.00 a bit steep.
I was hoping somebody on the forum had used/tried one of these devices that worked for them.

A little less analogue, and a lot more crap.

Just wondering..... what happens if you try and use a HDMI extender over homeplugs? Just a thought, not used video senders for years tbh, and HDMI ones never seem to get good reviews overall. Always assumed extenders using cat cables was the only way really for HD.

You could also use digital modulator, you would need to run a coax and use a freeview receiver in your den. The newer ones from Technomate also support the magic eye system for your remote signals.

The homeplug power-line LAN interfaces do not have the high frequency response needed for the HDMI to CAT 5/6 converters, the HDMI to CAT 5/6 interfaces need two CAT 5/6 cables to handle the HDMI HD signals, and have to be dedicated cables.

Any other signals running on top (or below) of the HDMI signals would cause all sorts of problems, the power line interface adapters have handshaking signals to find each other.

Thanks to everybody for your responses.
Running cable is not possible as the 30 Meters between the "mancabin" and the house is used for tractor and trailer to get into my very large back garden, and the Mrs does not want to see cables in the sky when she looks out the patio door.
Is there a SCART to a HDMI converter?

Can you dig a trench??/ This way a 3/4 inch PVC conduit can be run out to the mancabin.

All you would then need would be 2 CAT 5 or 6 cables out to the mancabin and the two HDMI to CAT 5/6 adapter, plus the SCART to HDMI adapter.

A method I used some years ago was making my own UHF transmitter.
Feed RF output of modulator (works with either analogue SD or digital HD modulators - for a while I used old VCRs fed with composite video from stb) into a UHF amplifier. Feed UHF amplifier to a portable TV UHF aerial. On receiving TV plug in portable aerial and tune TV to modulator output channel (may also work with main aerial if connected). With varying powers of UHF amplifiers I was able to get good reception from 10 meters up to 100 meters.

Strictly speaking this is illegal but if you live in the sticks and have no nearby neighbours then no problems

So, where did you get your transmitting licence from?:-lmao

(OTOH, many years ago when I worked at HP at Filton, Bristol, we had a roof-mounted EMI test range. That needed to be calibrated, which meant transmitting from one antenna to another up to 30m away. We were in clear sight of the TV transitter towers South of Bristol and the BAE Systems plant at Filton aerodrome - no licence but never got caught! :-lmao)

Ham radio operators can transmit SSTV on certain UHF channels, the equipment is available, but no one that I know of is doing digital HDTV.

I got my experimental TV license back in the 70's, I could go up to 1500 watts ERP if needed.

Rolls Royce. They subcontract HP for their IT stuff. Head offices are in Derby but RR obviously have a huge presence in Filton. I did some contract work there...

RR were probably somewhere at Filton at the time (late 1980's) but it was mainly BAE (or whatever it was called at the time) - took our first HP Bristol (mainly a storage peripherals R&D and manufacturing site at the time - but now long gone, I think) product into the BAE Environmental test labs for some shock & vibration testing, and it then stayed there for 2-3 weeks when they went on strike :-doh
