: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

: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

:02:54. > :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

:03:11. > :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

: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
