The digital TV switchover is the process of turning off the UK's analogue TV signal and replacing it with a digital signal.
The digital TV switchover is
Government policy. It will mean that almost everyone will be able to
receive digital TV through an aerial (Freeview).
Digital TV also uses less broadcast space which means that after
switchover, there will be more room for new services such as wireless
broadband, local TV and High Definition Television (HDTV). To keep your TV service, you will need to convert your TVs to digital
before your area’s switchover date.
Digital TV offers new ways to enjoy your TV service:
Greater choice of TV channels
New features such as on-screen listings, interactivity, audio description and subtitling for people with visual and audio impairments.
Optional additional channels and services including premium channels(e.g movies, sports), broadband and telephony.
