Digital Audio Broadcasting (DAB)

Digital audio broadcasting (DAB) transmits digital signals rather than the analog audio signals traditionally used in broadcast radio. DAB is broadcast on terrestrial networks, with future prospects for satellite broadcasting. Apart from receiving high-quality audio entertainment via the radio, programs can be accompanied by text, such as lyrics. The DAB-IP variant used by Virgin U.K. can support video.
