:00:34. > :00:41.Now it is time for.... -- time for It may sound like a lot of noise

:00:41. > :00:45.but this week we look at the Secret Life of static. Tablet in the - we

:00:45. > :00:48.check out the readers with an appetite for more than just books.

:00:48. > :00:54.Saving your memories before they fade. We look at the technology

:00:54. > :01:00.that can give your old foe days a facelift. We have the old -- the

:01:00. > :01:05.latest technology news and the look at how to make your own game in

:01:06. > :01:11.which -- Webscape. Around the world, TV services that have been

:01:11. > :01:15.broadcasting for decades are being switched off. Old analogue signals

:01:15. > :01:21.are being cleared from the Airways and being replaced with digital

:01:21. > :01:26.signals. The result of this is that lots of the radio spectrum is being

:01:26. > :01:30.freed up but that extra space will not remain free for long. We look

:01:30. > :01:37.at how be broadcast spectrum will be carved up as soon as your TV

:01:37. > :01:44.pictures have faded into the ether. In 1936, broadcasting history was

:01:44. > :01:48.made. Television signals were transmitted from the BBC studios at

:01:48. > :01:53.Alexandra Palace. For the first time, sound and vision from across

:01:53. > :02:03.the group could crackle into life at the nation -- in the nation's

:02:03. > :02:04.

:02:04. > :02:13.living rooms. The cameras and crews have long since fallen silent. Soon

:02:13. > :02:21.we will have to make the switch to digital television. As silent as

:02:21. > :02:30.our airwaves will be as soon as we make way for completely digital

:02:30. > :02:37.television broadcasts. Different devices each use different parts of

:02:37. > :02:43.the broadcast spectrum. The UK spectrum will be auctioned in 2012.

:02:43. > :02:48.OFCOM is designing this auction. In the UK and other countries around

:02:48. > :02:54.the world we are replacing analogue broadcasts with digital. The

:02:54. > :02:59.switch-off process started in the UK in 2007 and is due to finish in

:02:59. > :03:09.2012. One of the great benefits of doing that's it will create massive

:03:09. > :03:11.

:03:11. > :03:15.deficiencies in the way the spectrum is used. -- that is. As we

:03:15. > :03:20.prepare to switch off analogue television in favour of digital, a

:03:20. > :03:24.wide variety of different technologies are poised to take

:03:24. > :03:29.advantage of the broadcast space freed up by the death of all school

:03:29. > :03:33.analogue television. Analogue television broadcasts used up more

:03:33. > :03:39.of the spectrum than digital does so news services can take advantage

:03:39. > :03:43.of the space which will become available on the air waves. The

:03:43. > :03:53.mobile phone operators are the team is to grab the largest slice of

:03:53. > :03:59.

:03:59. > :04:04.this newly freed up they want to -- newly freed up broad band. There is

:04:05. > :04:10.a huge demand for mobile data, being fuelled by smartphones and

:04:10. > :04:14.mobile data services such as e-mail, video streaming, messaging services,

:04:14. > :04:18.mapping services and social networking. Studies have been made

:04:18. > :04:23.that mobile broadband is the application that delivers the

:04:23. > :04:33.greatest economic and societal benefits and mobile broadband means

:04:33. > :04:38.

:04:38. > :04:43.that new technology can be deployed. 3G and 4G - Imagine if you were

:04:43. > :04:49.building a motorway and you wear it using for decks on the motorway.

:04:49. > :04:55.You would not use more land but you can have more traffic passing

:04:55. > :04:58.through it. The mobile phone companies are tipped to grab the

:04:58. > :05:05.lion's share of the broadcast spectrum but the story does not end

:05:05. > :05:11.there. Some technology companies see the old-fashioned television

:05:11. > :05:16.signal as the gift that keeps on giving. Television broadcasts used

:05:17. > :05:22.parts of the spectrum back trouble very well through solid objects.

:05:22. > :05:26.Most of the spectrum is not used. The white space project found this.

:05:26. > :05:31.That is technology that tries to use parts of the spectrum that are

:05:31. > :05:40.not being used so we can use it on an ad-hoc basis. Brad Symes

:05:40. > :05:46.spectrum here and pass some traffic through it. -- grab some spectrum.

:05:47. > :05:52.Engineers working in conjunction with the Cambridge White Spaces

:05:52. > :05:58.Consortium are trying to bring the internet to people in remote areas.

:05:58. > :06:08.We are trying to bring the internet while asleep to people who do not

:06:08. > :06:08.

:06:08. > :06:15.have an ADSL connection. It is you UHF signal, using the gaps in the

:06:15. > :06:20.TV channels at the moment. You used radio modulation techniques to send

:06:20. > :06:30.the signal to remote places. We have a base station here which we

:06:30. > :06:31.

:06:31. > :06:35.are using to broadcast a signal and used for communications,

:06:35. > :06:42.specifically with the aim to provide all well with an internet

:06:42. > :06:47.service. Prior to the trial, Wed speeds in this all well home were

:06:47. > :06:51.typically between 100 or 200 kilobits per second. The trial

:06:51. > :06:59.technology has increased those speeds to eight megabits per second,

:06:59. > :07:02.making it possible to stream video or use services like Skype. The

:07:02. > :07:05.trials in Cambridgeshire are ongoing but one thing is certain -

:07:05. > :07:14.analogue television is on the way out but the air waves analogue

:07:14. > :07:24.television uses are set to be just as crowded. Now I look at this

:07:24. > :07:24.

:07:25. > :07:30.week's -- a wee look at this week's techniques. Mark Zuckerberg's

:07:30. > :07:38.thanksgiving for prayers have been published online after it uses

:07:38. > :07:48.alerted the internet to security problems with the social networking

:07:48. > :07:51.

:07:51. > :07:55.giant. Apple's stored that supplies the books fought the iPhone and

:07:56. > :08:00.iPad is likely to come under scrutiny after it the European

:08:00. > :08:10.Union's anti-trust watchdog has launched an investigation into

:08:10. > :08:33.

:08:33. > :08:36.whether they have been using Google is celebrating its 10

:08:36. > :08:42.billion Thor app download from the Andra Market but a lot of them are

:08:42. > :08:47.free. Despite the rapid growth of And rode smartphones, the quality

:08:47. > :08:52.of the apps might have an effect on whether people buy anything.

:08:52. > :08:56.Exports users will gain more controls of the televisions through

:08:56. > :09:06.Kinect as new software rolls out this week, improving boys' control

:09:06. > :09:10.

:09:10. > :09:14.and more television content. -- voice control. We have spent a lot

:09:14. > :09:19.of the last year or so talking about tablets and tablet operating

:09:19. > :09:22.systems but long before there were any tablets there was a different

:09:22. > :09:32.kind of portable device that allowed you to read your content on

:09:32. > :09:46.

:09:46. > :09:55.the move - e-reader. There are seven-inch tablets masquerading as

:09:55. > :09:59.e-reader. This is the Kindle Fire, which has proved massively

:09:59. > :10:03.disruptive. It is opening up the tabloid market to an entire

:10:03. > :10:08.different demographic because it is half the price of one of the fully

:10:08. > :10:18.featured tablets. This is Amazon's attempt to create a cat making door

:10:18. > :10:35.

:10:35. > :10:45.which is not just a reading device, which can take on Apple. This is a

:10:45. > :10:47.

:10:47. > :10:54.similar attempt. This is a classic Android feel. This is another one

:10:54. > :10:59.from Amazon. Are they any good as tablets? Should you consider buying

:10:59. > :11:05.one of these. They are not fully featured tablets. You do not get

:11:05. > :11:09.the screen real-estate for newspapers, if you like. You have

:11:09. > :11:14.something which is a bit bigger than a smartphone. You do not have

:11:14. > :11:19.Bluetooth or GPS, you do not have a camera or a microphone. You have a

:11:19. > :11:24.slightly slower processor. All these things have less storage.

:11:24. > :11:29.There is no 3G option. You will not be satisfied with a device like

:11:29. > :11:31.this if you worry power user but if you want to get into a tablet

:11:32. > :11:38.experience and want something at half the price of the fully

:11:38. > :11:48.featured tablets but would spend perhaps a bit more than a

:11:48. > :11:48.

:11:48. > :11:53.traditional e-reader, this could be for you. They are good to read

:11:53. > :12:03.books on. You can read books even in dark conditions, which cannot

:12:03. > :12:13.with and the reader. These are back of it. -- backlit. Outdoors they

:12:13. > :12:14.

:12:14. > :12:18.are not as good. They are reflective. They need a big, heavy

:12:18. > :12:28.battery so they are not as white and -- light and not as comfortable

:12:28. > :12:33.

:12:33. > :12:37.Last week we told you how to convert old film into high-quality

:12:37. > :12:41.digital copies. If you are archiving this material for future

:12:41. > :12:45.generations, you obviously want the best results possible and here, you

:12:45. > :12:49.are not limited to the quality of the originals. Our reporter has

:12:49. > :12:53.been testing some of the new technology that improves our

:12:53. > :13:00.memories and makes them better than you.

:13:00. > :13:05.-- better than the new. My late father locked away hundreds

:13:05. > :13:09.of home movies and negatives from the 1950s. After capturing them

:13:09. > :13:13.digitally, I realised that some of the originals had begun to

:13:13. > :13:18.deteriorate. Even the best kept images eventually succumbed to

:13:18. > :13:22.chemical breakdown. But once again and, they are frozen in time. But

:13:22. > :13:27.then the challenge is how to undo the damage.

:13:27. > :13:33.Experts agree that you should avoid using the free software that often

:13:33. > :13:36.comes with a scanner. To get the best quality results, this man is

:13:36. > :13:42.using photo quality plug-ins and stand-alone software.

:13:42. > :13:47.The biggest problem is often his visual noise - meaning of the grain

:13:47. > :13:53.found in dark areas of film. Fortunately, the algorithms used to

:13:53. > :14:00.detect that are getting better and better. Noise capital fixer is one

:14:00. > :14:10.of -- noise Sanaa fixer is one programme that improves the image

:14:10. > :14:18.and avoids it looking too soft. Noise is only one aspect of the

:14:18. > :14:23.photo restoration. Perfectly Clear can do all sorts of things to

:14:23. > :14:25.dramatically clean up an image. But crucially, it automatically

:14:25. > :14:31.controls the order in which those steps are done.

:14:31. > :14:35.You generally find noise removal at the beginning. If you can get a

:14:35. > :14:40.clean image at the beginning, you can then compare it to sharpening

:14:40. > :14:46.the images later. Often only small areas of a photo

:14:46. > :14:53.are degraded. A method has been invented to specifically it just

:14:53. > :15:02.any part of an image. I can put a control. On the damaged

:15:02. > :15:06.area and I can fix certain areas. It really helps because pictures

:15:06. > :15:12.don't fade uniformly. Sometimes they are fed in different areas.

:15:12. > :15:21.Some bargains have become industry -- some plug ends have become

:15:21. > :15:26.industry standards. Prince present a different

:15:26. > :15:30.challenge especially if they are severely damaged. The process can

:15:30. > :15:33.be complicated although there are books that can help but not

:15:33. > :15:40.everybody has the time nor the skill to bring back their photos to

:15:40. > :15:44.a pristine condition. Holocaust su suion Rosen treasures her

:15:44. > :15:49.post Second World War two collection of photographs. Every

:15:49. > :15:53.family men be -- at memory prior to that was destroyed by the Nazis.

:15:53. > :15:59.This image of her children is one she is particularly fond off of.

:15:59. > :16:03.This picture when I go to bed at night I curse this picture. When

:16:03. > :16:07.you came into this room, you could not help but notice it because it

:16:07. > :16:13.really sort of look to you. The after many decades, every trace

:16:13. > :16:21.of colour has vanished. So Marion has taken her photo to a

:16:21. > :16:23.restoration expert. He quickly comes to the conclusion

:16:23. > :16:29.that there photograph is so faded that automated colour detection

:16:29. > :16:35.software will be useless. How ever there are some hints of

:16:35. > :16:40.what she will helpful -- be helpful. I presumed that this area was

:16:40. > :16:45.natural wood, so that gives me one reference point. Of course at the

:16:45. > :16:50.skin tone gives me another. Ultimately, he decides he will have

:16:50. > :16:54.to paint their colours by hand. Sebastien is a part technical

:16:54. > :16:59.expert and part historian. He can often pinpoint a period of time by

:16:59. > :17:05.looking for clues. For example, American wedding photographs were

:17:05. > :17:08.devoid of smiles before 1925. Marion's Botha meanwhile has a new

:17:08. > :17:10.lease of life. Would you like to see how it came

:17:10. > :17:14.out? I would.

:17:14. > :17:17.He ate it is. I, my goodness!

:17:17. > :17:23.What do you think of that was mac he would not think it is the same

:17:23. > :17:28.picture. It is beautiful.

:17:28. > :17:32.I am glad you like it. Her memory is triggered seeing the

:17:40. > :17:46.She has returned home with a photograph she is convinced is

:17:46. > :17:51.better than the original. My own family portrait of my sister

:17:51. > :17:59.and I also benefited from the human eye. No software I don't get away

:17:59. > :18:04.the exact colour and make-up of my tracksuit. -- knows software are

:18:04. > :18:08.our own. It has taken hundreds of hours to upgrade my late father's

:18:08. > :18:13.library of the images that hopefully it will be worth it as in

:18:13. > :18:17.many more generations to come are able to enjoy them.

:18:17. > :18:22.Were you one of those children who would bark yourself a weight in

:18:22. > :18:28.your bedroom with your BBC Micro trying to write a computer game?

:18:28. > :18:32.Yes that was me and everybody else in this team. Today's children do

:18:32. > :18:39.not get the same opportunity to practise the nuts and bolts of

:18:39. > :18:44.programming. That said, they can still have a go at codeine again.

:18:44. > :18:50.-- coding again. These days you do not need any

:18:50. > :18:54.experience. Just a simple package that you can download free. These

:18:54. > :18:59.games are built using flash and there are some basic templates

:19:32. > :19:36.your game, it can be uploaded to the website for comments from the

:19:36. > :19:40.community. Although this package looks incredibly complicated at

:19:40. > :19:44.first, it really is just step-by- step logic that will all fall into

:19:44. > :19:50.place once you have covered the basics and after mastering their

:19:50. > :20:00.game creation system, why not try a mobile game? This is a great

:20:00. > :20:03.

:20:03. > :20:12.resource if you fancy your hand at game design. Do you ever get the
