	Wat is DAB?
		Voor de naam Eureka 147 werd gekozen, omdat een technische corporatie bestaat onder de naam Eureka.
		Eureka 147 ontwikkelde uiteindelijk het DAB-standard – het digitale radio systeem – dat de luisteraars een geluidskwaliteit biedt dat gelijk staat aan het geluid van de cd-speler en, naast de mogelijkheid om gebruik te maken van extra services, ook de uitzending goedkoper zal maken.
		Het was tijd om het Eureka 147 Consortium te versmelten met het World DAB forum, dat zich bezighoudt met het implementeren van het DAB systeem.

	Digital Raido -- The Eureka 147 DAB System
		Eureka 147 DAB is a reliable, multi-service, digital radio broadcasting system, designed specifically for robust reception by mobile, portable, and fixed receivers, using simple non-directional antennas.
		The Eureka 147 DAB system provides both the listener and the broadcaster with new opportunities and significant benefits compared with existing analogue radio systems.
		The Eureka 147 DAB system ensures that radio is well prepared for this revolution, and the commitment of the BBC to implementing DAB will ensure that the British public will be well served by digital radio, at the earliest possible opportunity.

		It concluded, with strong support from the Steering Board, that the WorldDMB IRC was the best way of focusing information sources, resources and outputs in the Project Office, which will be the location for all information and registration requests.
		The WorldDMB IRC collects information from many sources, such as the Eureka 147 Consortium and WorldDMB experts, the EBU library, ETSI and various standards bodies, and other related organisations such as the RDS Forum.
		'Customers' of the WorldDMB IRC are expected to be: Eureka 147 and WorldDMB members; corporate organisations - newly interested in Digital Radio, regardless of size; individuals, including journalists, students and interested members of the public.

	DIGITAL RADIO BROADCASTING (DRB) - Where are we up to? (Site not responding. Last check: )
		Eureka 147 technology combines several radio programs (and any data) into a single multiplexed data stream known as an 'ensemble' and delivers this to an advanced digital receiver which can do much more than simply provide audio to the listener.
		As with Eureka 147, it has also been under development for several years and has reached the point where the basic design has been completed, satellite construction has started and receiver design is well advanced.
		Broadcasters in the USA are currently reluctant to adopt systems such as Eureka 147 that use new spectrum as they are concerned that the transition to new spectrum could have a serious impact on existing market shares.

	Synchronization method and system for a digital receiver - Patent 6058101
		An audio input signal of the Eureka 147 DAB system is generally encoded with a masking-pattern universal subband integrated coding and multiplexing ("MUSICAM") to divide a signal into subbands and to minimize hearing threshold and masking to achieve data reduction.
		In mode 1, for example, this pseudoperiodicity is of 128 samples or bits because of the repetitive pattern of the time-frequency-phase parameters, h.sub.0 j, h.sub.1 j, h.sub.2 j, and h.sub.3 j, that appear sequentially in the PR symbol.
		The duration of the guard interval T.sub.g of the Eureka 147 signal is approximately 1/4 of the symbols' duration T.sub.u, and the symbols in the guard interval are reproduced from the final 1/4 of the symbols.

		In the fourth quarter of last year, some Eureka radio manufacturers such as Roberts Radio were able to drop prices to about $165 as newer, smaller chipset costs dropped, in turn lowering manufacturing costs.

	Digital Audio Broadcasting - Wikipedia, the free encyclopedia
		Digital Audio Broadcasting (DAB), also known as Eureka 147, is a technology for broadcasting of audio using digital radio transmission.
		DAB (or Eureka-147) was developed as a research project for the European Union (Eureka project number EU147), which started in 1987 on initiative by a consortium formed in 1986.
		Eureka 147 DAB uses a wide-bandwidth broadcast technology and typically spectra have been allocated for it in Band III (174–240 MHz) and L band (1452–1492 MHz), although the scheme allows for operation almost anywhere above 30 MHz.

	Synchronization method and apparatus for guard interval-based OFDM signals - Patent 5991289
		In the case of the Eureka 147 system, the predetermined delay should be set to equal the duration of the useful symbols, T.sub.u.
		Specifically for the Eureka 147 system signal, the high-to-low transition occurs at approximately 4/5 of the symbol period and the low-to-high transition occurs at the end of the symbol period or the beginning of the next symbol period.
		Therefore, since the signal level of the Eureka 147 system during the null symbol is below that of noise, the null symbol may be detected by a power estimator.

		That system, known as the Eureka 147, or DAB, uses an entirely new set of frequencies that gives broadcasters the power to transmit not only news and CD-quality music, but pictures and videos as well.
		Because the type of frequencies used by the Eureka 147 in the U.S. are reserved for the military, the specific technology can’t be developed here.
		And although radio listeners here won’t have all the advantages of the Eureka 147 technology, the new digital radio will still be an improvement.

	L band at AllExperts
		L band (20-cm radar long-band) is a portion of the microwave band of the electromagnetic spectrum ranging roughly from 0.39 to 1.55 GHz.
		It is used by some communications satellites, and by terrestrial Eureka 147 digital audio broadcasting (DAB).
		In the United States, the L band is held by the military for telemetry, thereby forcing digital radio to in-band on-channel (IBOC) solutions.

	C. Crane Company - The Digital Revolution is Coming to Your Radio, Part 2 (Site not responding. Last check: )
		Instead of going with the Eureka 147 system, which the BBC has been using since 1995, NAB opted for something called the In-Band/On Channel (IBOC) system, developed by USA Digital Radio (now partnered with Lucent in Ibiquity).
		There are several ideas as to why NAB opted to go with IBOC instead of Eureka 147, and, at the risk of making controversy, I'll mention a couple views here.
		Initially, NAB intended to go with the Eureka 147 system, based largely on tests done both in Canada and in the US (by NASA) that concluded Eureka 147 was more reliable than IBOC.
