Wanting to distribute HD all over the house

[Onceler2]

I am wanting to switch our video/audio to high definition,the house is wired with quad sheild coax need something that will modulate the HD to a TV channel so it can be distributed all over the house on existing wire to be picked up by the HDTVs HD tuners like a Channel plus but one that handles HD
Thanks

Maybe with commercial CATV equipment, something like this: http://www.blondertongue.com/Agile-QAM-Modulator/Agile_QAM_Modulators.php

But they cost upwards of $1000US.

Also, Philips is supposed to have one in May for about $300 (USD).

I haven't tried either, so I can't comment on them.

Good Luck!

neither of these do what I need them to

So you have an antenna and want to split it out to multiple TV sets?

Or you have cable with no cable box and want to split it out to multiple TV sets?

Or you have dbs (sat)?

Or a computer feeding a single DVI-D out?

Or what?

It's the closest thing I could find, and the info was supplied free of charge.

Thankyou for the information.
I have an antenna which goes to the channel plus,also on the channel plus there are DVD and direct TV modulated from video/audio in modulated on 2 different channels so that the TVs recieving the signal can view any of these just by changing channels.
I have 2 channel plus' set up this way each one distributes to four coax runs so there are eight alltogether.
I want to get HD DTV and have it distributed in a similar way.
