DCAN 14: Siting and Design of Radio Telecommunication Equipment
2.24 Digital terrestrial broadcasting will in most cases use existing TV rooftop aerials for domestic reception. The signals received are transmitted from broadcast masts. The current analogue services will in time be replaced with digital broadcasting for both radio and television, although both technologies will have to run in parallel for a period. Digital broadcasting will add to the range of services, for example, greater choice, interactive programmes, home shopping and internet access.
