Re: Digital TV



Nigel,

Many thanks for your reply it has proved very useful.

I am sure I can probably use my existing Idratek HA for the IR
control (in addition it would also mean when I send the OFF command
the television is switched off by the wall plug rather than just
standby)

The RF route has some appeal in that the integrated digital tuners
mean each room can select different channels, whereas the Sky route
would seem to require a STB and feed from the dish (maximum of 3
choices assuming Sky + and 2 x Sky).

However, the Kat5 route looks good for high quality distribution for
example using DVD etc. For now I think I may go RF but drop 2 Co-
axial and 2 Cat5e to the wallplate for each TV.

you could distribute Digital Terrestrial this way and have a receiver
at each TV location (probably integrated with the TV). This would
also allow you to use the RF2 connection on your SKY box to
distribute that to the Tellys and use the remote eyes by each TV to
control the SKY box. Of course this means people in other rooms could
change the Sky channels you are watching so some discipline is
required.

or other device with a modulated o/p using something like this

allow you to share, for example,
a single freeview receiver across the house to all the tellys (as
long as it has a modulated o/p).

modulated RF route and adding all the bits together could cost a few
bob so it may be better to look at the design, possibly in phases,
and asses the costs... You will also have to deal with other channels
on the RF system from neighbouring transmitters as well as 'Taboo
Channels' see Keith Doxey's explanation here

Many systems use this as a way of sending TV, See www.kat5.tv
<http://www.kat5.tv/>  for more details.
Even Sky are looking at
connecting TVs in the home at HD using a central box (server) and 4
remote connections (HDMI?) so you can independently watch HD TV
around the house....
