Re: TV and sound over CAT5

[akitson@xxxxxxx]

Keith,

OK so whats Composite Video and Audio.  Is RF TV the stuff we get from
teh arial.  Isn't there some way of applying a simple converter and
turning it into something that can be run.  On the sound front I read
elsewhere that it should be possible to use a balanced signal.  DO you
know of any boxes that can take the output from the amp and sned it
down and then convert it back at the other end.  Sorry to be a
ignoramous about all this stuff, but yoru help is appreciated.

Regards
Ashley.
