Types of Digital TV
Digital TV can be broadcast in different ways, such as via satellite or fibre-optic cable. This short guide will tell you more about each method of digital TV signal broadcast, and the relevant providers.
DTTV – Digital Terrestrial Television
This is the free-to-air digital service which replaced analogue TV. The method of broadcasting is similar to analogue in that your aerial receives the signal, but the picture and sound quality is greatly improved.
The channels that were previously available through analogue without subscription, such as BBC One, BBC Two, ITV1, Channel 4 and Channel 5, are all included, as well as several +1 and sister stations that are also subscription-free. DDTV allows for a wider range of channels, whilst improving quality, which is one of the reasons why it was decided that the nation should switch to digital.
