RF Video distribution with a twist

Just planning an install as we are gutting a house and gonna live in it.

My plan is to be able to distribute the output of the V+ cable box, DVD Player around the house (same channel on diff sets) and also to have a new ariel run in, and be able to run freeveiw in rooms too. I would like to be able to hook some kind of magic eye device so i can control the V+ from other rooms if possible. I also would like the coax to be able to distribute the Virgin cable feed which will be revealed below....

Thoughts...

All kit is to go in the pantry under the stairs.
Run a new ariel on the roof, and terminate this in the pantry.
Run good quality coax from the pantry to 3 bedrooms, kitchen/diner, and living room.
In each room, have a coax faceplate/direct cable into TV set.
In the lounge, run 3 coax cables to the pantry.
1 Feed from pantry into the TV set
2 Feed from the pantry carrying the virgin media signal into the v+ box (i wanted all my services in the pantry, with virgin terminating in there, and me distributing the virgin cable signal internally)
3 Return feed from a 2/3/4 way modulator in the lounge, that can modulate the DVD Player, and the Virgin box, and send that back into the pantry, and ultimatly into some kind of distribution amp with 3 inputs (TV ariel, modulated signal from Modulator, and also a direct cable feed so i could connect a cable box to the bedroom/kitchen sockets if required in the future.

Is this acheivable/overboard or totally the wrong way to do this?

I will also be running CAT5 into all rooms at the same time for networking, could i use this as well/instead of?

Thanks
Rich

Re: RF Video distribution with a twist

No, you need to use co-ax.
I would suggest a multi output amplifier to do the splitting.

Re: RF Video distribution with a twist

The first question is wht screens you are planning to feed. Anything above 32" or so would very poor with an RF cable. Freeveiw will be ok but the RF out from the dvd and virgin+ box will be bad. So I would consider using the CAT5e cable to share a component video signals around rather than the RF.

The next problem is how to share the Cable TV signal throughout the property. The simple answer is that you can not do it. It needs a specailist amp with a return path amplifer in to be able to pass the comms signals back to the cable tv operators.

HTH a little.

Re: RF Video distribution with a twist

If you are running cat5 why not use that for stereo Audio and Composite video (will be better than RF) and not much more money.

If your using Cat 5 Baluns you may as well use S video as the baluns are the same price give or take, the problem would be to get DVD and Virgin you'd need some kind of swicher and distribution or ideally a matrix switcher which does get expensive very quickley.

you also need to think about control as you'd need to control the switcher to change between virgin and DVD (as well as controlling the DVD and V boxes) a dinky link or similar may do the job (running on some of a cat 5) or a TV link plus if your integrating with a sky box.

My only suggestion would be think about what you want to achieve now and what you may want in the futre and the run cabling for that and add in a spare, cable is cheap when your installing it anyway, ripping up walls and floors to run an extra cat 5 later is a nightmare.

I''d say 2 Co-ax and 4 Cat5's to a local equipment location /TV from your main hub is not unreasonable and should allow you to do pretty much anything you want.

Re: RF Video distribution with a twist

-sp- is giving good advice the norm is 2 cat5e and 2 coax (these can fit in a double UK box easily buit not harm in running a couple of extra cat5 perhpas 2 coax and 2 cat5 to a double box and then 2 cat5 to single. This is great for all rooms for phone and data connections
