Standard which describes the method of transmitting digital audio.
Both a generic term and the proprietary name given to a transmission system for radio which uses parts of the upper end of the VHF spectrum. Around eight stations are bundled together into 'multiplexes' of simultaneous transmission on a given receiving frequency.
In the past, sound was transmitted via the analog formats of AM (amplitude modulation) and FM (frequency modulation). Today, pure, crisp, uninterrupted sound is delivered to satellite systems using DAB. The sound is transformed into binary code, which is then sent to a receiver and translated back to its perfect original form.
Another term for digital terrestrial radio.
(DAB) The generic name given to the new generation of radio transmission using digitally encoded audio waveforms.
DAB Digital Audio Broadcasting (DAB) is an audio broadcasting system that enables the transmission not only of CD-quality audio, but of characters, images and video. The industry standard is Eureka-147.
A radio wave comprised of digital information that is decoded by a compatible radio receiver into sound. Because the receivers read only the digital code, and ignore fluxuations in either the amplitude and frequency of the carrier wave, content is unaffected by atmospheric conditions, or subject to multipath distortion.
Digital Audio Broadcasting (DAB), also known as Eureka 147, is a technology for broadcasting of audio using digital radio transmission. DAB uses multiplexing and compression to combine multiple audio streams onto a single broadcast frequency called a DAB ensemble. Other digital audio broadcasting systems are listed in the article on digital radio.
