RE: Confusion getting homevison onto TV

["Kenneth Watt" <kennethwatt@xxxxxxx>]

Graham,

This is on my "to-do" list as well! It seems nigh on impossible
with so many
different connections and sources that we (mostly) all seem to use. For
example, most of the TV/movies I watch are routed by S-Video from the VHS
player or DVD; even the old LD player is SV out. The reason being that for
my main viewing I generally use the projector, but elsewhere (obviously)
it's plain old CRT's. Luckily if I watch the TV it is only on one channel
only and switch using external tuners/sources (I regard TV's etc. as
monitors and nothing more) but anyone else in the house would not know this
and therefore, while I might get the message no-one else would.

I have a problem even hooking up external cameras because of this as,
effectively, I would have to modulate an RF signal round the house for all
the CRT's and have that signal taken, somehow, onto something that can
convert from RF to S-Video or I live without that feature where I mainly
watch TV. The something to convert RF to S-Video remains a mystery apart
from another video with S-Video out capability, but since standards
converter cost so much another VCR might just be the cheaper option.

As to the pop-ups and overlays I don't know, yet to get to that bit!

Subject: [ukha_d] Confusion getting homevison onto TV

I want to be able to show homevison messages on TVs around the house, with
the messages broadcast over the top of the existing TV program, is this
possible? I can see that it is possible to have a composite video feed
passed into Homevision and then the 'combined image' to be sent back out as
composite video. I can take a composite feed and modulate it so that it
appears on a dedicated channel. I can also use a signal booster/distributor
to pass UHF around the house.

I can see that if I had an aerial feed into a video recorder, took a
composite video feed out of that and into homevision, took a composite
video
feed (with overlay) out of homevision and into an rf modulator, took the rf
output from the modulator and into the booster/distributor I would then
have
'TV overlayed with Homevision' throughout the house, but everyone would be
watching the same channel to see the messages.

Am I missing some simple solution or is it impossible to achieve what I
want
to do.

Just in case this lot doesn't make sense, here is the bottom line:

Can I have homevision messages displayed over the top of terestrial TV
simultaneously on two TVs that are watching different channels?

Regards

Graham
