Television in the UK is changing.
Between 2007 and 2012 (depending on your location) the government will switch off the analogue TV signal.
This process of turning off the analogue signal and changing to the new digital signal is called the digital swithcover.
After the digital switchover has taken place only TV's and video recording equipment that have been adapted or upgraded will be able to receive digital television programmes.
However when the TV sets and video recording equipment have been adapted or upgraded, you will be able to get all the channels you recieve today through an aerial, and many more as standard (including digital channels from the BBC including BBC3, BBC4, Cbeebies, BBC News 24 and independant channels like, ITV2, ITV3 and More4. The coverage of Five which currently has limited coverage through the UK today, will also be significantly extended after the switchover.
Any analogue television can be converted with a set top box, either a digital terrestrial, digital cable, digital satellite or broadband / DSL box.
Alternatively, another option is to you buy an integrated digital television (iDTV) with an inbuilt digital tuner.
Some areas in the UK will not be able to receive digital terrestrial services until the digital switchover has taken place, but it is quick and easy to perform an online postcode check to see what you can receive in your area.
A normal television licence is all that is needed to watch analogue or digital television.
