Noobie question

Dear Folks,

I read the FAQ, but didn't see my question answered, so here I am.

From the FAQ
----------------------------
Q. What is component video ?

A. The "normal" hookups for TV are "composite video" and "S-video".
Composite video is normal video on a single wire, just like a VHS
camera outputs. S-video was a supposedly advanced standard. However,
neither of these standards was adquete to deliver true HDTV.
Component hookups give each of the three primary colors in an HDTV
signal its own cable. This is the most prevailent way to hook
up HDTV. Other methods are S-VGA and digital.
----------------------------

1. Is a "Component hookup" just a standard RCA cable?
2. Is there a seperate cable for the audio?
3. I'm building a new home and was considering running 2 coax cables
throughout the house. Is there a way to modulate the HD video and
audio and send that over coax, and demodulate on the other end to plug
into multiple HDTV's? The reason I ask is that I'm considering
getting a HD DVR and would like to have that DVR capability throughout
the entire house.

Thanks!

Yes. You will find some are better than others. The bandwidth requirement
for video is much higher than for audio. Usually they come in threes, color
coded to RGB (although they don't really carry Red, Green, and Blue the same
way VGA does.)


> 2. Is there a seperate cable for the audio?

Yes. Two or more in fact.

Not today. You are talking about creating your own HDTV modulator. AFAIK,
they are not within reach of consumers yet.

You will have to settle for SD for now.

Three of them, actually. And it is more correctly a 75-ohm shielded cable
with RCA connections.

>2. Is there a seperate cable for the audio?

Yes. Depending on what you are hooking up, this may take the form of a
stereo pair, or an optical or coaxial digital audio connection.

Not within a consumer realm that I know of. However, your DVR may have a
standard-def (NTSC) output as well, and this can be modulated using existing
methods. Also, additional DVRs are cheap (typically under $10/month from the
cable company); if you can afford multiple HDTVs you might as well get multiple
DVR cable boxes to feed them.

1. Component uses 3 separate coax cables (with RCA ends) to carry video -
like RGB (as in VGA) except encoded as luminance and color differences
(Y-Pb-Pr) to reduce noise sensitivity.
2. yes.. audio is separate, DD5.1 on optical or coax
3. carrying HD in analog for long distances is bad, remodulation is not
really an option AFAIK.
Posiblity looks like DVI/Toslink extenders but it looks pricey -

I know of no networked HD distribution solutions at present although there
is talk of a wireless 802.11g distribution system to be built into HD
components. You may be SOL on remoting the DVR for a while. In the long
term, I suspect there will eventually be TCP/IP solutions that ride on
anything capable over 20Mb/sec like Ethernet 100BaseT or better.

But DO get an HD DVR - they are really great and will change the way you
watch HDTV
