          DIGITAL SWITCHOVER PROGRAMME  2009

                                WHAT IS IT ALL ABOUT.

   The country is heading into a new a revolution in Television Broadcast standards. Currently we are using an analogue transmission system which has been in place approximately 70 yrs and has changed very little since the early days of television.

  With the arrival of Digital Television much more will be available to the consumer including Interactive services, H.D.T.V. (not from transmitters until the switchover is complete), and much more channels than currently be broadcast in analogue format (approx 8 digital can be compressed into 1 analogue broadcast channels bandwidth).

   
             HOW WILL IT AFFECT US. (WHAT YOU WILL NEED)

  OLDER TELEVISIONS

      The older T.V.s contain analogue tuners only and these will not work when the switchover happens in order to carry on using these a Digital Freeview box will be needed and this will do the job and act as a replacement for your t.v. s tuner.

   Digital T.V.s 

     Newer T.V.s may contain a Digital Tuner if the Television has the D.V.B. logo on the front or the rear of the set then this indicates that the set has an integrated Digital  Tuner not all T.V.s that say the are Digital Ready actually contain these tuners so make sure you ask the sales people first.

             DIGITAL RECEPTION WHAT'S NEEDED

  Digital Television Aerial reception is slightly different  from the Analogue  signals as each channel carries approx 8 Digital compressed channels, which means that if one of these channels is weak through your existing T.V. Aerial then a few channels will break up or disappear altogether.

   A good quality T.V. Aerial will help and must be aligned using a Digital T.V. Aerial meter to ensure that all Digital frequencies are being received  otherwise channels will be missing a good quality T.V. Aerial fitted on Heavy duty brackets will cost £110.00 fully fitted with a 2 yr warranty, more rooms can be added to this system and we offer a complete four room upgrade for £230.00 fully fitted (includes all new brackets and cabling) Go to our Aerial page for more info on T.V. Aerials.

      These are the Signal Levels needed to have trouble free viewing for Digital Television any more Signal or any less can cause Digital Breakup.
