digital radio

DAB digital radio sets come equipped with a small screen which carries information about the programme you're listening to. This may be a plot summary to a play, the name of the track currently being played, email addresses, up to the minute sports results or competition details.

Who inverted DAB?

Digital Audio Broadcasting or 'DAB digital radio' has been developed by a consortium of manufacturers and broadcasters. The BBC pioneered DAB digital radio and was the first broadcaster in the UK to build a transmission network and start broadcasting DAB in 1995.

The advantages of DAB radio

The robust nature of DAB transmissions does away with the problem of the hiss and fade (multipath interference) that can spoil analogue radio transmissions. This is particularly good news for listeners to BBC Radio Five Live who can now hear the latest news and sport without all the usual problems associated with Medium Wave reception.

DAB signals are also far less likely to be affected by adverse weather conditions or local sources of interference - like pirate radio stations.

DAB technology allows broadcasters to transmit far more radio stations within the same comparable amount of radio spectrum compared to FM. It was this extra capacity that allowed the BBC to launch the five 'digital only' services in 2002 - in addition to our established stations: BBC Radio 1 to 5 as well as the BBC World Service. The flexible nature of our national DAB radio mutliplex means that the BBC can create secondary services - allowing us to offer Radio 4's Long Wave content via DAB, and double the coverage capacity of Radio Five Live with its sister channel; Five Live Sports Extra.

Digital radio text & data

Have you ever heard a song on the radio and wanted to know who it is by or what it's called, or tuned into speech radio and wanted to know what the programme is about or who is speaking?

DAB digital radio sets come equipped with a small screen which carries information about the programme you're listening to. This may be a plot summary to a play, the name of the track currently being played, email addresses, up to the minute sports results or competition details.

Some stations also scroll news headlines and other up-to-date information. Some of the latest DAB products can pick up a broadcast E.P.G (Electronic Programme Guide) which provides free, useful information programme information for up to 7 days in advance prior to broadcast , allowing users to programme the set to record a particular show automatically - or even an entire series of programmes.
