a) NRSC (National Radio Systems Committee) term for the next generation of digital radio equipment.

b) Modulations for sending digital rather than analog audio signals by either terrestrial or satellite transmitter with audio response up to compact disc quality (20 kHz). c) DAB was started as EUREKA project EU 147 in 1986. The digital audio coding process called MUSICAM was designed within EUREKA 147 by CCETT. The MUSICAM technique was selected by MPEG as the basis of the MPEG-1 audio coding, and it is the MPEG-1 Layer II algorithm which will be used in the DAB system. The EUREKA 147 project, in close cooperation with EBU, introduced the DAB system approach to the ITU-R, which subsequently has been contributing actively for the worldwide recognition and standardization of the DAB system. EBU, ETSI and EUREKA 147 set up a joint task committee with the purpose of defining a European Telecommunications Standard (ETS) for digital sound broadcasting, based on the DAB specifications. ETSI published the EUREKA 147 system as standard ETS 300 401 in February 1995, and market adoption is forthcoming; the BBC, for instance, plans to have 50% transmission coverage in 1997 when DAB receivers are being introduced to the public.
