Now it is time for.... -- time for It may sound like a lot of noise

:00:34.:00:41.

but this week we look at the Secret Life of static. Tablet in the - we

:00:41.:00:45.

check out the readers with an appetite for more than just books.

:00:45.:00:48.

Saving your memories before they fade. We look at the technology

:00:48.:00:54.

that can give your old foe days a facelift. We have the old -- the

:00:54.:01:00.

latest technology news and the look at how to make your own game in

:01:00.:01:05.

which -- Webscape. Around the world, TV services that have been

:01:06.:01:11.

broadcasting for decades are being switched off. Old analogue signals

:01:11.:01:15.

are being cleared from the Airways and being replaced with digital

:01:15.:01:21.

signals. The result of this is that lots of the radio spectrum is being

:01:21.:01:26.

freed up but that extra space will not remain free for long. We look

:01:26.:01:30.

at how be broadcast spectrum will be carved up as soon as your TV

:01:30.:01:37.

pictures have faded into the ether. In 1936, broadcasting history was

:01:37.:01:44.

made. Television signals were transmitted from the BBC studios at

:01:44.:01:48.

Alexandra Palace. For the first time, sound and vision from across

:01:48.:01:53.

the group could crackle into life at the nation -- in the nation's

:01:53.:02:03.
:02:03.:02:04.

living rooms. The cameras and crews have long since fallen silent. Soon

:02:04.:02:13.

we will have to make the switch to digital television. As silent as

:02:13.:02:21.

our airwaves will be as soon as we make way for completely digital

:02:21.:02:30.

television broadcasts. Different devices each use different parts of

:02:30.:02:37.

the broadcast spectrum. The UK spectrum will be auctioned in 2012.

:02:37.:02:43.

OFCOM is designing this auction. In the UK and other countries around

:02:43.:02:48.

the world we are replacing analogue broadcasts with digital. The

:02:48.:02:54.

switch-off process started in the UK in 2007 and is due to finish in

:02:54.:02:59.

2012. One of the great benefits of doing that's it will create massive

:02:59.:03:09.
:03:09.:03:11.

deficiencies in the way the spectrum is used. -- that is. As we

:03:11.:03:15.

prepare to switch off analogue television in favour of digital, a

:03:15.:03:20.

wide variety of different technologies are poised to take

:03:20.:03:24.

advantage of the broadcast space freed up by the death of all school

:03:24.:03:29.

analogue television. Analogue television broadcasts used up more

:03:29.:03:33.

of the spectrum than digital does so news services can take advantage

:03:33.:03:39.

of the space which will become available on the air waves. The

:03:39.:03:43.

mobile phone operators are the team is to grab the largest slice of

:03:43.:03:53.
:03:53.:03:59.

this newly freed up they want to -- newly freed up broad band. There is

:03:59.:04:04.

a huge demand for mobile data, being fuelled by smartphones and

:04:05.:04:10.

mobile data services such as e-mail, video streaming, messaging services,

:04:10.:04:14.

mapping services and social networking. Studies have been made

:04:14.:04:18.

that mobile broadband is the application that delivers the

:04:18.:04:23.

greatest economic and societal benefits and mobile broadband means

:04:23.:04:33.
:04:33.:04:38.

that new technology can be deployed. 3G and 4G - Imagine if you were

:04:38.:04:43.

building a motorway and you wear it using for decks on the motorway.

:04:43.:04:49.

You would not use more land but you can have more traffic passing

:04:49.:04:55.

through it. The mobile phone companies are tipped to grab the

:04:55.:04:58.

lion's share of the broadcast spectrum but the story does not end

:04:58.:05:05.

there. Some technology companies see the old-fashioned television

:05:05.:05:11.

signal as the gift that keeps on giving. Television broadcasts used

:05:11.:05:16.

parts of the spectrum back trouble very well through solid objects.

:05:17.:05:22.

Most of the spectrum is not used. The white space project found this.

:05:22.:05:26.

That is technology that tries to use parts of the spectrum that are

:05:26.:05:31.

not being used so we can use it on an ad-hoc basis. Brad Symes

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

:06:08.:06:15.

TV channels at the moment. You used radio modulation techniques to send

:06:15.:06:20.

the signal to remote places. We have a base station here which we

:06:20.:06:30.
:06:30.:06:31.

are using to broadcast a signal and used for communications,

:06:31.:06:35.

specifically with the aim to provide all well with an internet

:06:35.:06:42.

service. Prior to the trial, Wed speeds in this all well home were

:06:42.:06:47.

typically between 100 or 200 kilobits per second. The trial

:06:47.:06:51.

technology has increased those speeds to eight megabits per second,

:06:51.:06:59.

making it possible to stream video or use services like Skype. The

:06:59.:07:02.

trials in Cambridgeshire are ongoing but one thing is certain -

:07:02.:07:05.

analogue television is on the way out but the air waves analogue

:07:05.:07:14.

television uses are set to be just as crowded. Now I look at this

and more television content. -- voice control. We have spent a lot

:09:10.:09:14.

of the last year or so talking about tablets and tablet operating

:09:14.:09:19.

systems but long before there were any tablets there was a different

:09:19.:09:22.

kind of portable device that allowed you to read your content on

:09:22.:09:32.
:09:32.:09:46.

the move - e-reader. There are seven-inch tablets masquerading as

:09:46.:09:55.

e-reader. This is the Kindle Fire, which has proved massively

:09:55.:09:59.

disruptive. It is opening up the tabloid market to an entire

:09:59.:10:03.

different demographic because it is half the price of one of the fully

:10:03.:10:08.

featured tablets. This is Amazon's attempt to create a cat making door

:10:08.:10:18.
:10:18.:10:35.

which is not just a reading device, which can take on Apple. This is a

:10:35.:10:45.
:10:45.:10:47.

similar attempt. This is a classic Android feel. This is another one

:10:47.:10:54.

from Amazon. Are they any good as tablets? Should you consider buying

:10:54.:10:59.

one of these. They are not fully featured tablets. You do not get

:10:59.:11:05.

the screen real-estate for newspapers, if you like. You have

:11:05.:11:09.

something which is a bit bigger than a smartphone. You do not have

:11:09.:11:14.

Bluetooth or GPS, you do not have a camera or a microphone. You have a

:11:14.:11:19.

slightly slower processor. All these things have less storage.

:11:19.:11:24.

There is no 3G option. You will not be satisfied with a device like

:11:24.:11:29.

this if you worry power user but if you want to get into a tablet

:11:29.:11:31.

experience and want something at half the price of the fully

:11:32.:11:38.

featured tablets but would spend perhaps a bit more than a

:11:38.:11:48.
:11:48.:11:48.

traditional e-reader, this could be for you. They are good to read

:11:48.:11:53.

books on. You can read books even in dark conditions, which cannot

:11:53.:12:03.

with and the reader. These are back of it. -- backlit. Outdoors they

:12:03.:12:13.
:12:13.:12:14.

are not as good. They are reflective. They need a big, heavy

:12:14.:12:18.

battery so they are not as white and -- light and not as comfortable

:12:18.:12:28.
:12:28.:12:33.

Last week we told you how to convert old film into high-quality

:12:33.:12:37.

digital copies. If you are archiving this material for future

:12:37.:12:41.

generations, you obviously want the best results possible and here, you

:12:41.:12:45.

are not limited to the quality of the originals. Our reporter has

:12:45.:12:49.

been testing some of the new technology that improves our

:12:49.:12:53.

memories and makes them better than you.

:12:53.:13:00.

-- better than the new. My late father locked away hundreds

:13:00.:13:05.

of home movies and negatives from the 1950s. After capturing them

:13:05.:13:09.

digitally, I realised that some of the originals had begun to

:13:09.:13:13.

deteriorate. Even the best kept images eventually succumbed to

:13:13.:13:18.

chemical breakdown. But once again and, they are frozen in time. But

:13:18.:13:22.

then the challenge is how to undo the damage.

:13:22.:13:27.

Experts agree that you should avoid using the free software that often

:13:27.:13:33.

comes with a scanner. To get the best quality results, this man is

:13:33.:13:36.

using photo quality plug-ins and stand-alone software.

:13:36.:13:42.

The biggest problem is often his visual noise - meaning of the grain

:13:42.:13:47.

found in dark areas of film. Fortunately, the algorithms used to

:13:47.:13:53.

detect that are getting better and better. Noise capital fixer is one

:13:53.:14:00.

of -- noise Sanaa fixer is one programme that improves the image

:14:00.:14:10.

and avoids it looking too soft. Noise is only one aspect of the

:14:10.:14:18.

photo restoration. Perfectly Clear can do all sorts of things to

:14:18.:14:23.

dramatically clean up an image. But crucially, it automatically

:14:23.:14:25.

controls the order in which those steps are done.

:14:25.:14:31.

You generally find noise removal at the beginning. If you can get a

:14:31.:14:35.

clean image at the beginning, you can then compare it to sharpening

:14:35.:14:40.

the images later. Often only small areas of a photo

:14:40.:14:46.

are degraded. A method has been invented to specifically it just

:14:46.:14:53.

any part of an image. I can put a control. On the damaged

:14:53.:15:02.

area and I can fix certain areas. It really helps because pictures

:15:02.:15:06.

don't fade uniformly. Sometimes they are fed in different areas.

:15:06.:15:12.

Some bargains have become industry -- some plug ends have become

:15:12.:15:21.

industry standards. Prince present a different

:15:21.:15:26.

challenge especially if they are severely damaged. The process can

:15:26.:15:30.

be complicated although there are books that can help but not

:15:30.:15:33.

everybody has the time nor the skill to bring back their photos to

:15:33.:15:40.

a pristine condition. Holocaust su suion Rosen treasures her

:15:40.:15:44.

post Second World War two collection of photographs. Every

:15:44.:15:49.

:15:49.:15:53.

This image of her children is one she is particularly fond off of.

:15:53.:15:59.

This picture when I go to bed at night I curse this picture. When

:15:59.:16:03.

you came into this room, you could not help but notice it because it

:16:03.:16:07.

really sort of look to you. The after many decades, every trace

:16:07.:16:13.

of colour has vanished. So Marion has taken her photo to a

:16:13.:16:21.

restoration expert. He quickly comes to the conclusion

:16:21.:16:23.

that there photograph is so faded that automated colour detection

:16:23.:16:29.

software will be useless. How ever there are some hints of

:16:29.:16:35.

what she will helpful -- be helpful. I presumed that this area was

:16:35.:16:40.

natural wood, so that gives me one reference point. Of course at the

:16:40.:16:45.

skin tone gives me another. Ultimately, he decides he will have

:16:45.:16:50.

to paint their colours by hand. Sebastien is a part technical

:16:50.:16:54.

expert and part historian. He can often pinpoint a period of time by

:16:54.:16:59.

looking for clues. For example, American wedding photographs were

:16:59.:17:05.

devoid of smiles before 1925. Marion's Botha meanwhile has a new

:17:05.:17:08.

lease of life. Would you like to see how it came

:17:08.:17:10.

out? I would.

:17:10.:17:14.

He ate it is. I, my goodness!

:17:14.:17:17.

What do you think of that was mac he would not think it is the same

:17:17.:17:23.

picture. It is beautiful.

:17:23.:17:28.

I am glad you like it. Her memory is triggered seeing the

- a quick fix on the digital image. -- the dress.

:17:37.:17:40.

She has returned home with a photograph she is convinced is

:17:40.:17:46.

better than the original. My own family portrait of my sister

:17:46.:17:51.

and I also benefited from the human eye. No software I don't get away

:17:51.:17:59.

the exact colour and make-up of my tracksuit. -- knows software are

:17:59.:18:04.

our own. It has taken hundreds of hours to upgrade my late father's

:18:04.:18:08.

library of the images that hopefully it will be worth it as in

:18:08.:18:13.

many more generations to come are able to enjoy them.

:18:13.:18:17.

Were you one of those children who would bark yourself a weight in

:18:17.:18:22.

your bedroom with your BBC Micro trying to write a computer game?

:18:22.:18:28.

Yes that was me and everybody else in this team. Today's children do

:18:28.:18:32.

not get the same opportunity to practise the nuts and bolts of

:18:32.:18:39.

programming. That said, they can still have a go at codeine again.

:18:39.:18:44.

-- coding again. These days you do not need any

:18:44.:18:50.

experience. Just a simple package that you can download free. These

:18:50.:18:54.

games are built using flash and there are some basic templates

:18:54.:18:59.

available. Or you can create a game at from scratch, and porting

:18:59.:19:01.

characters, enemies and establishing behaviours and an

:19:01.:19:06.

:19:06.:19:14.

pretty much a master and can be accessed through the health centre.

:19:28.:19:32.

your game, it can be uploaded to the website for comments from the

:19:32.:19:36.

community. Although this package looks incredibly complicated at

:19:36.:19:40.

first, it really is just step-by- step logic that will all fall into

:19:40.:19:44.

place once you have covered the basics and after mastering their
