if you are feeding several TV's around from one media server, its more
cost effective to use a HDMI modulator than to use several sets of HDMI
to ethernety adapters

I suspect, and others seem to agree, you could only pipe SD, not HD, TV around like that. It might be possible to hack something but I wouldn't
be the person to ask how to do that.

Its specs seem contradictory ...
    - DVB-T, not DVB-T2, which seems to imply SD only
    + 1080p (FHD)
... so what exactly to do these specs refer to? Particularly, does the '1080p' refer only to the HDMI output, or both the HDMI and the
modulated output?
refers to the modulated output, which will be SD only, while the HDMI
output will be the same as the input up to a max of 1080p.
And quite pricey if you buy it assuming it will give you HD modulated
output and then discover that too late that it won't!
It *does* give you one HD TV channel from a HDMI input.

In theory you can't be 100% sure every TV ever made will accept that combination (DVB-T, H.264, HD resolution) but it'd be unusual if it
didn't because I think that combination has, in the past, been used for broadcasts in a few parts of the world.

yes you are right as the kitchen TV has to be replaced as it cannot
display MPEG4 content which is what this modulator produces plus it uses

Naturally I yield to your actual experience of using them, but I still
think I was right to point out what I saw as potential pitfalls.
Also, for a single TV it's still quite pricey compared with the examples
of HDMI over ethernet that I've linked.

the loft..... you'd have to run 4 lots of ethernet to each TV set and
also there is no gaurantee that you'd get 1 HMDI to many TV sets working properly as you'd need a hub of some description....

You'd still need one of those modulators for each HDMI source, so it's approximately n x £80 as opposed to n x £2x.

Sounds an absurdly over-complex setup which I find barely believable, as often I struggle to find anything at all I want to watch of an entire evening, let alone 6 items all at once, and especially as so much stuff
is downloadable now, eg the BBC's using GetIPlayer. However, if indeed
you really do *NEED* 6 DVB cards, which I find the least credible part
of your setup, put them all in one or two servers man enough to run them
all at once, control the cards remotely over the LAN, and stream the recordings over the LAN.
Nevertheless, taking your setup as a given, you need a many-sources-to-many-sinks system for your HDMI over ethernet, which
most probably will mean a semi-professional or professional setup, and
yes probably that will be on the expensive side, because the cheap
Chinese chow on places like Amazon is not geared to someone like you.
It's mostly one or perhaps just a few internal designs in myriads of differently badged boxes geared towards someone who just wants to link
one or more sinks to a single or small number of sources which is/are
some distance away in another room.
*If* you could buy, say 10-12 of the cheaper device pairs for about £60 each, connect them all to a suitable ethernet switch and have them work harmoniously together, that would be about £6-700, but would they
actually work together or just interfere with each other?! The problem
is rather like having two devices responding to the same remote control,
only here you have a need analogous to having several remote controls
each needing to be capable of controlling any one of several devices.
You need some way of configuring each HDMI transmitter unit to have a different identity from the others, and a way of telling each receiver
which transmitter unit's output it should be displaying at any one time.
 In my brief search, I couldn't find anything cheap that will
definitely do what you want, nothing that definitely couldn't do what
you want, but I suspect that all of it probably won't do what you want.
There are units designed to handle multiple HDMI sources, the largest
number of HDMI inputs I've seen on a single sender was 8, but the ones
I've seen seem to output only one of those at a time, whereas what you
need is for each source to be output constantly, and for the receivers
to pick and choose which of those sources they want to display:
https://www.amazon.co.uk/PW-DT2108-Splitter-Extender-Ethernet-Resolution-1X8-150m/dp/B077YTPF57/
problem no 1 is my TV sets have 4 or less HDMI sockets on the back.
You should only need to connect one HDMI over ethernet RX unit. See
above ...
Problem no 2 is even if I use HDMI switch boxes at each TV set or DVB
card, I'd have to run 10 x ethernet cables from the loft down to
*each* TV set and *each* DVB card. so thats 120 ethernet cable runs
instead of using the existing 12 freeview co-ax runs.
I'd've done that first and not bothered with the co-ax runs, because a network connection is much more versatile, and you could use WiFi,
though of course generally it's less reliable than cable, but would be alright if you have a good signal and good reception.
problem no 3 is that I'd have to replicate each one of the 10 HDMI
sources 12 times over via Active HDMI splitters and they are not cheap.
No, the whole point of ethernet is to allow to multiple devices to talk together at the same time over the same network cabling, so
theoretically at least it should be possible to use your normal LAN to
do what you want, it's merely a question of finding kit that uses
network technology in the right way. It may involve a lot of trawling through hardware specs or finding someone with good knowledge of this particular problem, but in the end you might find something not too
expensive that will do the job. Certainly, it should be possible.
However, I think you're approaching this in the wrong way. The problem you're giving yourself is exemplified by the fact that you're taking
digital sources, encoding them as digital data onto HDMI signals,
encoding these again to be carried over a network, encoding them back
onto HDMI signals again, before finally converting them into analogue
that you can see and hear. It would be far better and easier if you get everything into digital form and keep it as such as far as possible
along the connection route, only converting it into analogue at the
point that you actually use it. In other words, you need to cut out the informationally redundant middle conversions.
Almost everything I commonly use is already digitised and resides either
on this PC or on a server on my LAN. I only ever need to convert it to analogue at the final stage of using it. What this means in practice is that all my old analogue LPs/ACs/VCs/photos are all digitised, and all
my digital sources such as CDs/DVDs/MDs have been backed up, onto this
PC and/or a server, and to play/use any of them I simply double-click a file. Almost all, but not quite all, TV I want to watch I can download
via GetIPlayer or stream from the channel site. Being an amateur
musician once upon a time, I have a USB soundcard connected to a HiFi to
get decent sound, and am content to watch video on this or another
laptop monitor, but this laptop has an HDMI output which I could use if
I really wanted that big screen experience. It's true that my current
setup was largely enforced by my particular and perhaps rather peculiar current circumstances, but I find I don't miss one jot the big AV rack
that I used to have in my previous home, and the many problems that I
used to have in making the various bits of it work together. I have absolutely no need now to attempt the sort of conversions that you are plaguing yourself with, the gigabit LAN does everything, and, more or
less, it 'just works'.
For the sort of money you are talking about, you could get a decent NAS
with about 8TB or more, mine are 16TB, digitise/backup everything you
and the family need, save yourself all these connection problems, and it would be more or less future proof.
