What are the benefits of DTT?
One of the advantages of DTT is that it doesn’t require a dish to be installed on your roof or a cable to be laid to your house. And, like any digital TV system, DTT is much more economical in terms of the amount of bandwidth it uses than analogue terrestrial TV. In an analogue TV home, viewers in the UK can only generally receive five TV channels. But with DTT, you can (in principle) get up to 30 digital TV channels without needing to pay a subscription.

In addition to the extra channel choice available, DTT should generally offer much better picture and sound quality than analogue terrestrial TV (although this is not always the case in practice).

Other features include the ability to receive TV pictures in widescreen format, and to interact with TV programmes. Because of the way the DTT system used in the UK was originally designed, it will also be able to be used in the future for broadcasts to moving vehicles such as cars, buses or trains.
