Saving your memories before they fade. We look at the technology
that can give your old foe days a facelift. We have the old -- the
latest technology news and the look at how to make your own game in
which -- Webscape. Around the world, TV services that have been
broadcasting for decades are being switched off. Old analogue signals
are being cleared from the Airways and being replaced with digital
signals. The result of this is that lots of the radio spectrum is being
freed up but that extra space will not remain free for long. We look
at how be broadcast spectrum will be carved up as soon as your TV
pictures have faded into the ether. In 1936, broadcasting history was
made. Television signals were transmitted from the BBC studios at
Alexandra Palace. For the first time, sound and vision from across
the group could crackle into life at the nation -- in the nation's
living rooms. The cameras and crews have long since fallen silent. Soon
we will have to make the switch to digital television. As silent as
our airwaves will be as soon as we make way for completely digital
television broadcasts. Different devices each use different parts of
the broadcast spectrum. The UK spectrum will be auctioned in 2012.
OFCOM is designing this auction. In the UK and other countries around
the world we are replacing analogue broadcasts with digital. The
switch-off process started in the UK in 2007 and is due to finish in
2012. One of the great benefits of doing that's it will create massive
deficiencies in the way the spectrum is used. -- that is. As we
prepare to switch off analogue television in favour of digital, a
wide variety of different technologies are poised to take
advantage of the broadcast space freed up by the death of all school
analogue television. Analogue television broadcasts used up more
of the spectrum than digital does so news services can take advantage
of the space which will become available on the air waves. The
mobile phone operators are the team is to grab the largest slice of
this newly freed up they want to -- newly freed up broad band. There is
a huge demand for mobile data, being fuelled by smartphones and
mobile data services such as e-mail, video streaming, messaging services,
mapping services and social networking. Studies have been made
that mobile broadband is the application that delivers the
greatest economic and societal benefits and mobile broadband means
that new technology can be deployed. 3G and 4G - Imagine if you were
building a motorway and you wear it using for decks on the motorway.
You would not use more land but you can have more traffic passing
through it. The mobile phone companies are tipped to grab the
lion's share of the broadcast spectrum but the story does not end
there. Some technology companies see the old-fashioned television
signal as the gift that keeps on giving. Television broadcasts used
parts of the spectrum back trouble very well through solid objects.
Most of the spectrum is not used. The white space project found this.
That is technology that tries to use parts of the spectrum that are
not being used so we can use it on an ad-hoc basis. Brad Symes

Engineers working in conjunction with the Cambridge White Spaces
Consortium are trying to bring the internet to people in remote areas.
We are trying to bring the internet while asleep to people who do not
have an ADSL connection. It is you UHF signal, using the gaps in the
TV channels at the moment. You used radio modulation techniques to send
the signal to remote places. We have a base station here which we
are using to broadcast a signal and used for communications,
specifically with the aim to provide all well with an internet
service. Prior to the trial, Wed speeds in this all well home were
typically between 100 or 200 kilobits per second. The trial
technology has increased those speeds to eight megabits per second,
making it possible to stream video or use services like Skype. The
trials in Cambridgeshire are ongoing but one thing is certain -
analogue television is on the way out but the air waves analogue
television uses are set to be just as crowded. Now I look at this
week's -- a wee look at this week's techniques. Mark Zuckerberg's

of the last year or so talking about tablets and tablet operating
systems but long before there were any tablets there was a different
kind of portable device that allowed you to read your content on
the move - e-reader. There are seven-inch tablets masquerading as
e-reader. This is the Kindle Fire, which has proved massively
disruptive. It is opening up the tabloid market to an entire
different demographic because it is half the price of one of the fully
featured tablets. This is Amazon's attempt to create a cat making door
which is not just a reading device, which can take on Apple. This is a
similar attempt. This is a classic Android feel. This is another one
from Amazon. Are they any good as tablets? Should you consider buying
one of these. They are not fully featured tablets. You do not get
the screen real-estate for newspapers, if you like. You have
something which is a bit bigger than a smartphone. You do not have
Bluetooth or GPS, you do not have a camera or a microphone. You have a
slightly slower processor. All these things have less storage.
There is no 3G option. You will not be satisfied with a device like
this if you worry power user but if you want to get into a tablet
experience and want something at half the price of the fully
featured tablets but would spend perhaps a bit more than a
traditional e-reader, this could be for you. They are good to read
books on. You can read books even in dark conditions, which cannot

Last week we told you how to convert old film into high-quality
digital copies. If you are archiving this material for future
generations, you obviously want the best results possible and here, you
are not limited to the quality of the originals. Our reporter has
been testing some of the new technology that improves our
memories and makes them better than you.
-- better than the new. My late father locked away hundreds
of home movies and negatives from the 1950s. After capturing them
digitally, I realised that some of the originals had begun to
deteriorate. Even the best kept images eventually succumbed to
chemical breakdown. But once again and, they are frozen in time. But
then the challenge is how to undo the damage.
Experts agree that you should avoid using the free software that often
comes with a scanner. To get the best quality results, this man is
using photo quality plug-ins and stand-alone software.
The biggest problem is often his visual noise - meaning of the grain
found in dark areas of film. Fortunately, the algorithms used to
detect that are getting better and better. Noise capital fixer is one
of -- noise Sanaa fixer is one programme that improves the image
and avoids it looking too soft. Noise is only one aspect of the
photo restoration. Perfectly Clear can do all sorts of things to
dramatically clean up an image. But crucially, it automatically
controls the order in which those steps are done.
You generally find noise removal at the beginning. If you can get a
clean image at the beginning, you can then compare it to sharpening
the images later. Often only small areas of a photo
are degraded. A method has been invented to specifically it just
any part of an image. I can put a control. On the damaged
area and I can fix certain areas. It really helps because pictures
don't fade uniformly. Sometimes they are fed in different areas.
Some bargains have become industry -- some plug ends have become
industry standards. Prince present a different
challenge especially if they are severely damaged. The process can
be complicated although there are books that can help but not
everybody has the time nor the skill to bring back their photos to
a pristine condition. Holocaust su suion Rosen treasures her

This image of her children is one she is particularly fond off of.
This picture when I go to bed at night I curse this picture. When
you came into this room, you could not help but notice it because it
really sort of look to you. The after many decades, every trace
of colour has vanished. So Marion has taken her photo to a
restoration expert. He quickly comes to the conclusion
that there photograph is so faded that automated colour detection
software will be useless. How ever there are some hints of
what she will helpful -- be helpful. I presumed that this area was
natural wood, so that gives me one reference point. Of course at the
skin tone gives me another. Ultimately, he decides he will have
to paint their colours by hand. Sebastien is a part technical
expert and part historian. He can often pinpoint a period of time by
looking for clues. For example, American wedding photographs were
devoid of smiles before 1925. Marion's Botha meanwhile has a new
lease of life. Would you like to see how it came
out? I would.

Were you one of those children who would bark yourself a weight in
your bedroom with your BBC Micro trying to write a computer game?
Yes that was me and everybody else in this team. Today's children do
