If you remember, there were proposals for broadband internet through
the outside power supply and fears that it would be a huge source of
QRN.

Well, here it is again except that the digital data is TV. I doubt
this makes any difference as far as QRN is concerned..

TV to come through mains supply
By Mark Ward
Technology correspondent, BBC News website

Soon you could be piping digital TV around your home via power
sockets.

At the Cebit technology fair, German hi-tech firm Devolo is showing
off home networking technology that can handle signals from a set top
box.

While many firms are working on ways to route data via the mains power
circuits in the home, Devolo is among the first to use it to send TV
signals.

Further improvements to the home networking system will help it handle
cable and satellite TV signals.

Although many people are connecting up all the digital devices in
their home via dedicated computer cables, increasing numbers are
choosing networking technology that route data via the same wires that
supply electricity to each and every room.

Data network

The systems typically work using a specially adapted plug that acts as
a mini-hub to route data to devices around the house.

As a data network this system can be used to stream video to devices
in other rooms or to route internet-based TV to displays or gadgets.

Now Devolo has found a way to route standard digital TV signals over
the same infrastructure.

"It connects to the set-top box and converts that TV signal to an IP
signal," said Andre Jansen, a spokesman for Devolo.

IP, or internet protocol, is a standard for sending data across
networks.

"The adapter has a range of 200m," he told the BBC News website, "and
that's enough for a normal private household."

Devolo has yet to announce prices or availability of the home TV
network system.

At the moment the system can only route a single digital TV channel
over the network but Devolo aims to improve this soon so people can
watch different channels in different rooms.

Next year Devolo hopes to have ready a technology that can pipe
satellite and cable TV pictures around the home.
