About of DIGITAL AUDIO BROADCAST

Like this page? What is DAB digital radio? Digital Audio Broadcasting is a new transmission system bringing the benefits of digital to the world of radio.

. DAB technology allows broadcasters to transmit far more radio stations within the same comparable amount of radio spectrum compared to FM.

. DAB technology explained Who invented DAB? D igital A udio B roadcasting or 'DAB digital radio' has been developed by a consortium of manufacturers and broadcasters.

. The BBC pioneered DAB digital radio and was the first broadcaster in the UK to build a transmission network and start broadcasting DAB in 1995.

. This vastly reduces the potential for the broadcast to be corrupted during transmission by weather conditions, and other problems that can degrade the quality of reception. How is this different from FM? The 'multipath' interference which disturbs FM reception (caused by radio signals bouncing off buildings and hills) is eliminated within DAB signals.

. Some of the latest DAB products can pick up a broadcast E.P.G (Electronic Programme Guide) which provides free, useful information programme information for up to 7 days in advance prior to broadcast, allowing users to programme the set to record a particular show automatically - or even an entire series of programmes.

> Mobile Computing Definitions - Digital audio broadcasting Mobile Computing Definitions - powered by whatis.com BROWSE DEFINITIONS: Search for: - OR - Search this site: digital audio broadcasting Digital audio broadcasting (DAB), also known as digital radio and high-definition radio, is broadcasting in which audio is converted into a signal and transmitted on an assigned channel in the AM or (more usually) FM frequency range.

. DAB is said to offer compact disc - quality audio on the (frequency modulation) broadcast band and to offer FM-quality audio on the (amplitude modulation) broadcast band.

. Digital audio broadcast signals are transmitted in-band , on-channel ( IBOC ).

. A digital signal offers several advantages over conventional analog transmission, including improved sound quality, reduced fading and multipath effects, enhanced immunity to weather, noise, and other interference, and expansion of the listener base by increasing the number of stations that can broadcast within a given frequency band.

Digital Audio Broadcasting - Il DAB: cos'è? - Le reti SFN - sperimentazione RAI DAB - "Bouquet" DAB RAI - Introduzione del DAB in Italia - Futuri sviluppi del DAB - Impianti DAB in funzione

DAB: Digital Audio Broadcasting Questo sistema non è riuscito ancora, soprattutto in Italia, a oltrepassare il campo delle applicazioni sperimentali, seppure oramai portate avanti su aree geografiche sempre più vaste.

. IL DAB: cos'è ? Il DAB, Digital Audio Broadcasting è la più importante innovazione nel campo della radio dopo l'introduzione della stereofonia in Modulazione di Frequenza.

. Il sistema DAB è stato sviluppato in Europa, nell'ambito del progetto EUREKA EU-147, da un consorzio di industrie elettroniche, broadcaster, network provider ed istituti di ricerca.

. Gli obiettivi del Digital Audio Broadcasting si possono così riassumere: fornire una buona qualità del servizio all'utente senza richiedere occupazioni di banda superiori a quelli dei sistemi tradizionali ridurre la potenza necessaria per l'emissione a parità di area di servizio possibilità di realizzare delle reti isofrequenziali.

. Partecipazione alla giornata di studio dell'AIIT sul tema "La radiofonia terrestre in tecnica numerica DAB e servizi multimediali: la Rai presenta alcune applicazioni multimediali che sfruttano le possibilità offerte dal Digital Audio Broadcasting.

Welcome to WorldDAB | FAQ

. DAB stands for Digital Audio Broadcasting.

. For the broadcaster, DAB provides a means of reaching listeners with sound quality on an equal footing with the CD player, and the ability to offer extra, potentially revenue-creating, services.

. DAB therefore is taking the oldest of broadcast media into the digital age.

. Digital Audio Broadcasting provides crystal clear sound that is comparable to near CD quality - you can hear music as though you're in a first class concert hall, or listen to a discussion programme as though you're right in the studio.

. Some broadcasters will transmit extra data along with the radio programme which identifies what sort of programme it isâ€“for example, Classical Music or News.

. All DAB receivers have digital displays (including some with large liquid crystal screens), and broadcasters will have the option to transmit additional programme-associated data (or PAD for short).

. Some broadcasters might offer special concerts available only on payment (because DAB is flexible, new services like Pay channelsâ€“or extra conventional free-to-air channelsâ€“can be added without having to switch off the ones already on the air) which you would subscribe to on an individual or long-term basis.

digital audio broadcasting: Information From Answers.com

On this page: digital audio broadcasting DAB ( D igital A udio B roadcasting) The digital radio standard in most countries except for the U.S., which uses iBiquity's HD Radio, and Japan, which uses Terrestrial Integrated Services Digital Broadcasting (ISDB-T).

. digital audio broadcasting Digital audio broadcasting or DAB is a technology for broadcasting audio programming in digital form that was designed in the late 1980s.

. The acronym DAB is used both to identify the generic technology of digital audio broadcasting, and specific technical standards, particularly the standard described below.

. DAB should not be confused with other types of audio broadcasting generically referred to as, but which are in fact primarily based on analog technology with a few complementary digital features such as synthesized tuning and LCD frequency displays.

. Another case is digital video broadcasting - terrestrial services which, although designed for digital video broadcasts, often incorporate some digital audio channels to utilise spare bandwidth.

Fanfare FM - DAB Digital Radio News

A Fanfare Report! (Updated and Digital Audio Radio Broadcasting(DAR or DAB) What's Really Happening? The concept of 'digital radio' (DAR) while it may be in the back of every broadcasting executive's mind right now, is certainly not in evidence anywhere else, such as 'on-air' personnel singing the "I can't wait to sound like a CD" song.

. The concept was presented a few years back as "How broadcasting will be done in the future".

. As a result, limited licenses have been issued in both Canada and Europe to broadcasters who wish to experiment using the digital transmission system by simulcasting with their AM or FM broadcasts.

. Sometime this year, if there are enough receiver manufacturers in evidence, Canada's public broadcaster, the C.B.C., will begin transmitting digital programming.

. As of this writing, the broadcasters and broadcast authorities have begun looking to the manufacturers of radio receivers to take up the DAR cause and present a good selection of equipment to the market.

. If you want the list broken down by state, In-band On-channel ("IBOC") digital audio broadcasting ("DAB") provides for enhanced sound fidelity, improved reception, and new data services.

. This technology allows broadcasters to use their current radio spectrum to transmit AM and FM analog signals simultaneously with new higher quality digital signals.

. IBOC was designed to bring the benefits of digital audio broadcasting to analog radio while preventing interference to the host analog station and stations on the same channel and adjacent channels.

. IBOC technology makes use of the existing AM and FM bands (In-Band) by adding digital carriers to a radio station's analog signal, allowing broadcasters to transmit digitally on their existing channel assignments (On-Channel).

. IBOC technology will also allow for radios to be "backward and forward" compatible, allowing them to receive traditional analog broadcasts from stations that have yet to convert and digital broadcasts from stations that have converted.
