RE: sorry if naive - which is best - coax or kat5 ?

Hi Umar,

Before I start, I will say that I build the KAT5 units so may be ever so
slightly biased, but the info provided here is correct.

Coax is best suited to the distribution of UHF and Satellite signals,
basically any signal that is modulated. Any TV can then view any source but
items like you VCR and Digibox will be Mono sound only via RF distribution

For non cabled solutions you can get Video Senders that work on 2.4GHz and
will give you Stereo Sound, but as you will note from this list, they can
interfere with each other and Wireless LAN's (as Phil has discovered)

KAT5 is designed to distribute line level S-Video and Stereo Audio signals
around the home over KAT5. The ONLY way to distribute S-Video over Coax is
to use 2 coax cables which MUST be EXACTLY the same length. If the length
of
the two cables was different then the Luma (Brightness) and Chroma (Colour)
signals that make up the s-Video signal will arrive at your TV at different
times. This will lead to a picture where the colours are shifted to either
the left or right of the image like a badly printed newspaper. KAT5 will
give the same quality of picture that you would get if your DVD player was
plugged directly into the TV

Coax is definately the cheapest option but lacks the ability for your own
sources to modulate onto the cable with stereo sound unless you spend a lot
of money on a Nicam Encoder. Putting multiple channels onto coax is not as
easy at it sounds, there are certain channels that cant be used because
they
interfere with each other.

The KAT5 system is still developing. At the moment it is only a point to
point link although it can have multiple receivers off one transmitter. An
InfraRed control system is under development as well as a multi-source,
multi-zone switcher which will allow all your AV kit to be distributed
anywhere in the house (provided you installed plenty of CAT5 cable!)

Hope that helps

Keith

as the subject says. ie which is

cheaper
more reliable
better quality output
best suited to muti source, multi output

where can I find out more

again - apologies for naivety - new to this and cant find it at the moment

cheers

Umar
