DAB ensembles are groups of Digital audio broadcasting broadcasters transmitting multiple digital radio channels on a single radio transmission. Official DAB logo, found on compliant devices Digital Audio Broadcasting (DAB), also known as Eureka 147, is a technology for broadcasting of audio using digital radio transmission. ... Broadcasting is the distribution of audio and/or video signals which transmit programs to an audience. ... In telecommunications, transmission is the act of transmitting electrical messages (and the associated phenomena of radiant energy that passes through media). ... This article needs to be cleaned up to conform to a higher standard of quality. ... Channel, in communications (sometimes called communications channel), refers to the medium used to convey information from a sender (or transmitter) to a receiver. ... In telecommunications, transmission is the act of transmitting electrical messages (and the associated phenomena of radiant energy that passes through media). ...

The digital audio feeds from each radio station are multiplexed into one digital transmission, to be decoded by the receiver. While each station can use a different bitrate, and either monophonic or stereophonic (one or two channels of audio), all stations will have the exact same coverage area. Each ensemble can only have a certain maximum total bitrate, a sort of "bit budget" that participating broadcasters must work within. Increasing the number of stations on an ensemble requires lower quality audio, and while increasing audio quality requires removing audio channels. Digital audio comprises audio signals stored in a digital format. ... A radio station is an audio (sound) broadcasting service, traditionally broadcast through the air as radio waves (a form of electromagnetic radiation) from a transmitter to an antenna and a thus to a receiving device. ... In telecommunications, multiplexing (also muxing or MUXing) is the combining of two or more information channels onto a common transmission medium using hardware called a multiplexer or (MUX). ... A digital system is one that uses discrete values (often electrical voltages), especially those representable as binary numbers, or non-numeric symbols such as letters or icons, for input, processing, transmission, storage, or display, rather than a continuous spectrum of values (ie, as in an analog system). ... For other senses of the word code, see code (disambiguation). ... In radio terminology, a receiver is an electronic circuit that receives a radio signal from an antenna and decodes the signal for use as sound, pictures, navigational-position information, etc. ... In telecommunications and computing, bitrate (sometimes written bit rate, data rate or as a variable Rbit) is the number of bits that are conveyed or processed per unit of time. ... Monophonic can mean: In recorded audio, a monaural recording with only one channel. ... Stereophonic means having two channels of audio. ... Sound is a disturbance of mechanical energy that propagates through matter as a longitudinal wave, and therefore is a mechanical wave. ... In telecommunications and computing, bitrate (sometimes written bit rate, data rate or as a variable Rbit) is the number of bits that are conveyed or processed per unit of time. ... Look up budget in Wiktionary, the free dictionary. ...

The digital television equivalent is called a multiplex, though in some parts of the world, TV stations use a full channel for their own programming (one HDTV or multiplexed SDTV) and do not share with other stations. Digital television (DTV) is a telecommunication system for broadcasting and receiving moving pictures and sound by means of digital signals, in contrast to analog signals used by analog (traditional) TV. DTV uses digital modulation data, which is digitally compressed and requires decoding by a specially designed television set, or a... A television station is a type of radio station that broadcasts both audio and video to television receivers in a particular area. ... Projection screen in a home theater, displaying a high-definition television image. ... ...
