I know I'm a bit out of touch these days, but when I was in the
TV business, baseband 625line broadcast TV bandwidth was 50c/s to
5.5Mc/s. (never did catch on to this Hertz lark :-) )
Not arguing, just wondering what's changed.
nothing and everything...
PAL TV style video is the same as you describe, but when talking about
remote display technologies like video senders, remote KVM switches etc,
the phrase "video" is often referring to the video output of a computer
to its display.
A hi-res display running at say 1600 x 1200 with a refresh rate of 85Hz
will be running at a line rate over 100KHz rather than the usual 15KHz
for PAL, and pixel clock capable of displaying 1600 pixels per line is
going to push the video bandwidth required into the 100s of MHz
In the 50's they all said internal combustion engine would be extinct and we
would all have nuclear powered flying cars by 2000 ......... not too many of
them in my street.
If you are building a new house it makes total sense to flood wire with
CAT5, it is peanuts in price compared to building costs - and so what if in
the future you don't use it.
But it is a hell of a pain if you want it and didn't put in in during build
I have built a new place and put in several km's of CAT5 and also more than
a km of CT100.
I put multiple rums of each to every room, extra CAT5 to ceiling sensor
locations, alarm detectors, inside & out, possible projector locations etc.

I imagine your home must be lit up like a christmas tree to a passing
thunderstorm which is looking to dissipate some energy to the ground
Seriously though, if a lightning strike came to earth somewhere close
to your home I would expect all that extra wiring to act as a
conductive path to possibly take out the whole house. Have you taken
any precautions about that possibility?
Also, could you not use fibre optic, which doesn't have the lightning
issue to deal with. More expensive of course, but more than adequate
for future transmission speeds.
Just go along to B&Q and buy a home network cabling starter kit -- all
cabling bits and tools you need plus decent instruction -- Screwfix and
Maplin do similar kits but B&Q are on special offer and they also throw in
a free mouse.
