That's really helpful - as usual. Many thanks, BW (and since you were writing in the middle of the night, perhaps Pillow Bag should now be "Big Owl - Pal" ?!)
Have to embark on major re-wiring shortly - you've provided some great ideas, if I can face channelling all those walls :-(
That's the only bad thing about it. The cables, any cables, don't install themselves. Now if someone were to come up with an idea like a self installing system, it would make life a lot easier, Eh ?. :-))
Good luck with it.
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.Cheers,
Ian
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
I had no idea this was possible - do you know where I can find more details about exactly how to do this? I'm interested in using my PC to record video, and play back on the TV in the next room (which is already connected by CAT5).

A web search for "SCART to PC" or "PC Monitor to SCART" and variations of, brings up a few sites with loads of information. Look out for a switching box that connects a mass of units together and can distribute them to each other and does loads of magic tricks with video and audio. And for the work it can do, I think is somewhere in the region of 100 GBP's, so it ain't to expensive really.
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 time.
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. 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.
