DAB – Radio
Digital Audio Broadcasting. Pioneered by BBC Radio, DAB started in 1995 as a system of transmitting radio signals digitally. After a slow start due to lack of affordable receivers, DAB began to take off in 2001 as the cost of tuners came down and radios with DAB can be bought for under £50.
Offers distortion free, crystal clear radio reception with near CD quality sound, and additional text/data information such as name of station, disc playing, advertising and news. New digital –only radio stations are now transmitting, and virtually all radio stations in the UK transmit digitally. The DAB system conforms to the European standard known as Eureka 147 which uses digital compression to reduce the bit rate for each audio source, so that up to six stereo radio services can be multiplexed together, and a single frequency for each station can be used to cover the whole country.
