Tasks for the president of the European Council are ensuring the external representation of the EU, driving consensus and resolving divergences among member states, both during meetings of the European Council and over the periods between them. The European Council should not be mistaken for
640-487: A DAB ensemble can be increased by lowering average bit rates, but at the expense of the quality of streams. Error correction under the DAB standard makes the signal more robust but reduces the total bit rate available for streams. DAB broadcasts a single multiplex that is approximately 1.5 MHz wide (≈1,000 kilobits per second). That multiplex is then subdivided into multiple digital streams of between 9 and 12 programs. In contrast, FM HD Radio adds its digital carriers to
768-530: A DMB video subchannel can easily be added to any DAB transmission, as it was designed to be carried on a DAB subchannel. DMB broadcasts in South Korea carry conventional MPEG 1 Layer II DAB audio services alongside their DMB video services. As of 2017 , DMB is currently broadcast in Norway, South Korea, and Thailand. Fifty-five countries provide regular or trial DAB(+) broadcasts. In spectrum management ,
896-421: A combination of both higher audio quality and more stations. One of the most important decisions regarding the design of a digital radio broadcasting system is the choice of which audio codec to use because the efficiency of the audio codec determines how many radio stations can be carried on a fixed capacity multiplex at a given level of audio quality. Error-correction coding (ECC) is an important technology for
1024-564: A consortium formed in 1986. The MPEG-1 Audio Layer II ("MP2") codec was created as part of the EU147 project. DAB was the first standard based on orthogonal frequency-division multiplexing (OFDM) modulation technique, which since then has become one of the most popular transmission schemes for modern wideband digital communication systems. A choice of audio codec , modulation and error-correction coding schemes and first trial broadcasts were made in 1990. Public demonstrations were made in 1993 in
1152-468: A digital communication system because it determines how robust the reception will be for a given signal strength – stronger ECC will provide a more robust reception than a weaker form. The old version of DAB uses punctured convolutional coding for its ECC. The coding scheme uses unequal error protection (UEP), which means that parts of the audio bit-stream that are more susceptible to errors causing audible disturbances are provided with more protection (i.e.
1280-425: A hybrid system of supranational and intergovernmental decision-making, and according to the principle of conferral (which says that it should act only within the limits of the competences conferred on it by the treaties ) and of subsidiarity (which says that it should act only where an objective cannot be sufficiently achieved by the member states acting alone). Laws made by the EU institutions are passed in
1408-468: A lower code rate ) and vice versa. However, the UEP scheme used on DAB results in a grey area in between the user experiencing good reception quality and no reception at all, as opposed to the situation with most other wireless digital communication systems that have a sharp "digital cliff", where the signal rapidly becomes unusable if the signal strength drops below a certain threshold. When DAB listeners receive

#17327910313621536-552: A maximum bit rate that can be carried, but this depends on which error protection level is used. However, all DAB multiplexes can carry a total of 864 "capacity units". The number of capacity units, or CU, that a certain bit-rate level requires depends on the amount of error correction added to the transmission, as described above. In the UK, most services transmit using 'protection level three', which provides an average ECC code rate of approximately 1 / 2 , equating to
1664-404: A maximum bit rate per multiplex of 1,184 kbit/s. Various different services are embedded into one ensemble (which is also typically called a multiplex ). These services can include: Traditionally, radio programmes were broadcast on different frequencies via AM and FM , and the radio had to be tuned into each frequency as needed. This used up a comparatively large amount of spectrum for
1792-693: A pilot broadcast started in Bavaria in October 1995. In the UK, commercial stations started broadcasting in November 1999. For various reasons such as high receiver costs and limited reception, adoption of DAB had initially been slow, with the exception of the United Kingdom and Denmark. In the UK, DAB radio receivers were high selling and 10% of households owned a DAB radio as of 2005, helped by local manufacturers creating affordable receivers such as
1920-537: A reaction to World War I and its aftermath. In this light the first advances for the idea of European integration were made. In 1920 John Maynard Keynes proposed a European customs union for the struggling post-war European economies, and in 1923 the oldest organisation for European integration, the Paneuropean Union was founded, led by Richard von Coudenhove-Kalergi , who later would found in June 1947
2048-644: A receiver receives a signal that has been transmitted from the different transmitters that are part of an SFN, the signals from the different transmitters will typically have different delays, but to OFDM they will appear to simply be different multipaths of the same signal. Reception difficulties can arise, however, when the relative delay of multipaths exceeds the OFDM guard interval duration, and there are frequent reports of reception difficulties due to this issue when propagation conditions change, such as when there's high pressure, as signals travel farther than usual, and thus
2176-463: A rectangular byte interleaver rather than Forney interleaving in order to provide a greater interleaver depth, which increases the distance over which error bursts will be spread out in the bit-stream, which in turn will allow the Reed–Solomon error decoder to correct a higher proportion of errors. The ECC used on DAB+ is far stronger than is used on DAB, which, with all else being equal (i.e., if
2304-446: A relatively small number of stations, limiting listening choice. DAB is a digital radio broadcasting system that, through the application of multiplexing and compression, combines multiple audio streams onto a relatively narrow band centred on a single broadcast frequency called a DAB ensemble . Within an overall target bit rate for the DAB ensemble, individual stations can be allocated different bit rates. The number of channels within
2432-721: A result most radio stations on DAB have a lower sound quality than FM, prompting complaints from listeners. As with DAB+ or T-DMB in Europe, FM HD Radio uses a codec based upon the MPEG-4 HE - AAC standard. HD Radio is a proprietary system from iBiquity Digital Corporation , a subsidiary of DTS, Inc. since 2015, which is itself owned by Xperi Corporation since 2016. DAB is an open standard deposited at ETSI. DAB can give substantially higher spectral efficiency , measured in programmes per MHz and per transmitter site, than analogue systems. In many places, this has led to an increase in
2560-598: A right of unilateral withdrawal under Article 50 of the Treaty on European Union. In addition, the principle of subsidiarity requires that only those matters that need to be determined collectively are so determined. Under the principle of supremacy , national courts are required to enforce the treaties that their member states have ratified, even if doing so requires them to ignore conflicting national law, and (within limits) even constitutional provisions. The direct effect and supremacy doctrines were not explicitly set out in

This combination of Reed–Solomon coding as the inner layer of coding, followed by an outer layer of convolutional coding – so-called "concatenated coding" – became a popular ECC scheme in the 1990s, and NASA adopted it for its deep-space missions. One slight difference between the concatenated coding used by the DAB+ system and that used on most other systems is that it uses

4096-427: Is generally more efficient in its use of spectrum than analogue FM radio, and thus can offer more radio services for the same given bandwidth. The broadcaster can select any desired sound quality, from high-fidelity signals for music to low-fidelity signals for talk radio, in which case the sound quality can be noticeably inferior to analog FM. High-fidelity equates to a high bit rate and higher transmission cost. DAB
4224-467: Is inconsistent with EU law. It is not possible to appeal against the decisions of national courts in the CJEU, but rather national courts refer questions of EU law to the CJEU. However, it is ultimately for the national court to apply the resulting interpretation to the facts of any given case. Although, only courts of final appeal are bound to refer a question of EU law when one is addressed. The treaties give
4352-685: Is more robust with regard to noise and multipath fading for mobile listening, although DAB reception quality degrades rapidly when the signal strength falls below a critical threshold (as is normal for digital broadcasts ), whereas FM reception quality degrades slowly with the decreasing signal, providing more effective coverage over a larger area. DAB+ is a " green " platform and can bring up to 85 percent energy consumption savings compared to FM broadcasting (but analog tuners are more efficient than digital ones, and DRM+ has been recommended for small scale transmissions). Similar terrestrial digital radio standards are HD Radio , ISDB-Tb , DRM , and

The Court has been led by president Koen Lenaerts since 2015. The CJEU is the highest court of the European Union in matters of Union law . Its case-law provides that EU law has supremacy over any national law that
10496-430: The Union as a whole, though the exact delimitation has on occasions become a subject of scholarly or legal disputes. In certain fields, members have awarded exclusive competence and exclusive mandate to the Union. These are areas in which member states have entirely renounced their own capacity to enact legislation. In other areas, the EU and its member states share the competence to legislate. While both can legislate,

In May 2024, concerns rise, that the outcome of the elections in June, can undermine some of the crucial policies of the EU in the domain of environment, diplomacy, economy . The war in Ukraine by creating inflation, lowering life level created a possibility of strong changes in the 2024 elections. Since the end of World War II , sovereign European countries have entered into treaties and thereby co-operated and harmonised policies (or pooled sovereignty ) in an increasing number of areas, in
10752-492: The United Kingdom and the Netherlands. Malta was the first country to launch DAB+ in Europe in October 2008. South Africa began a DAB+ technical pilot in November 2014 on channel 13F in Band ;3. If DAB+ stations launch in established DAB countries, they can transmit alongside existing DAB stations that use the older MPEG-1 Audio Layer II audio format, and most existing DAB stations are expected to continue broadcasting until
10880-467: The United States has reached an agreement with Canada to restrict L-Band DAB to terrestrial broadcast to avoid interference. In January 2017, an updated DAB specification (2.1.1) removed Modes II, III and IV, leaving only Mode I. From an OSI model protocol stack viewpoint, the technologies used on DAB inhabit the following layers: the audio codec inhabits the presentation layer . Below that

In March 1948 the Treaty of Brussels was signed, establishing the Western Union (WU), followed by the International Authority for the Ruhr . Furthermore, the Organisation for European Economic Co-operation (OEEC), the predecessor of the OECD, was also founded in 1948 to manage
11520-459: The closure of FM signals in 2017 were as follows: SRG SSR , Switzerland's public-service broadcaster, will shut down its FM transmission infrastructure on 31 December 2024. The corporation concluded that maintaining FM broadcasts along with DAB+ and Internet streaming was no longer cost-effective, as due to widespread adoption of DAB+ the share of the public relying exclusively on FM was under ten percent and decreasing. All other FM broadcasters in

The Presidency of the council rotates between member states, with each holding it for six months. Beginning on 1 July 2024, the position is held by Hungary. The European Parliament is one of three legislative institutions of
11776-554: The countries of Central and Eastern Europe . Assessing the progress of European integration the Messina Conference was held in 1955, ordering the Spaak report , which in 1956 recommended the next significant steps of European integration. In 1957, Belgium , France , Italy , Luxembourg , the Netherlands , and West Germany signed the Treaty of Rome , which created the European Economic Community (EEC) and established
11904-589: The country must shut down or convert to DAB+ by 31 December 2026. As of 2021 : DAB uses a wide-bandwidth broadcast technology and typically spectra have been allocated for it in Band III (174–240 MHz) and L band (1.452–1.492 GHz), although the scheme allows for operation between 30 and 300 MHz . The US military has reserved L-Band in the USA only, blocking its use for other purposes in America, and
12032-487: The coverage area of DAB broadcasts, although by this time sales of receivers had only taken off in the United Kingdom (UK) and Denmark . In 2006 there were approximately 1,000 DAB stations in operation worldwide. As of 2018, over 68 million devices have been sold worldwide, and over 2,270 DAB services are on air. In October 2018, the WorldDAB organisation introduced an all-new logo for DAB (specifically DAB+) to replace
12160-472: The end of 2020, across all EU countries, all radios in new cars must be capable of receiving and reproducing digital terrestrial radio." Following the European Union's obligation in 2020 to include DAB+ receivers in new cars, Belgium has stopped all sales of analogue radio receivers from 1 January 2023. Thus, consumers are no longer able to purchase AM or FM receivers for domestic use. "The obligation to incorporate DAB+ for new cars and domestic radio receivers
12288-540: The ensuing détente led to establishment of a first truly pan-European body, the Conference on Security and Co-operation in Europe (CSCE), predecessor of the modern Organization for Security and Co-operation in Europe (OSCE). In 1979, the first direct elections to the European Parliament were held. Greece joined in 1981. In 1985, Greenland left the Communities , following a dispute over fishing rights. During

Institutional and budgetary reforms are being discussed in order to
12928-425: The interests of the EU as a whole rather than their home state. The leader of the 27 is the president of the European Commission (presently Ursula von der Leyen for 2019–2024, reelected for the 2024-2029 term), proposed by the European Council , following and taking into account the result of the European elections, and is then elected by the European Parliament. The President retains, as the leader responsible for
13056-447: The inverse relationship between these two parameters, and the overall OFDM channel bandwidth is 1.537 MHz. The OFDM guard interval for TM I is 0.246 ms, which means that the overall OFDM symbol duration is 1.246 ms. The guard interval duration also determines the maximum separation between transmitters that are part of the same single-frequency network (SFN), which is approximately 74 km for TM I. OFDM allows
13184-486: The member states can only legislate to the extent to which the EU has not. In other policy areas, the EU can only co-ordinate, support and supplement member state action but cannot enact legislation with the aim of harmonising national laws. That a particular policy area falls into a certain category of competence is not necessarily indicative of what legislative procedure is used for enacting legislation within that policy area. Different legislative procedures are used within
13312-508: The number of stations available to listeners, especially outside of the major urban areas. This can be further improved with DAB+ which uses a much more efficient codec, allowing a lower bitrate per channel with little to no loss in quality. If some stations transmit in mono, their bitrate can be reduced compared to stereo broadcasts, further improving the efficiency. European Union in Europe (dark grey) The European Union ( EU )
13440-456: The previous logo that had been in use since before DAB's initial launch in 1995. The term "DAB" most commonly refers both to a specific DAB standard using the MP2 audio codec, but can sometimes refer to a whole family of DAB-related standards, such as DAB+, DMB, and DAB-IP. WorldDAB , the organisation in charge of the DAB standards, announced DAB+, a major upgrade to the DAB standard in 2006, when
13568-523: The process, the UK left the European Union on 31 January 2020, though most areas of EU law continued to apply to the UK for a transition period which lasted until 31 December 2020.

After the economic crisis caused by the COVID-19 pandemic , the EU leaders agreed for the first time to create common debt to finance
13696-634: The related DMB . The DAB standard was initiated as a European research project called Eureka-147 in the 1980s. DAB has been under development since 1981 at the Institut für Rundfunktechnik (IRT). The first DAB demonstrations were held in 1985 at the WARC-ORB in Geneva, and in 1988 the first DAB transmissions were made in Germany. Later, DAB was developed as a research project for the European Union ( EUREKA ), which started in 1987 on an initiative by
13824-478: The same category of competence, and even with the same policy area. The distribution of competences in various policy areas between member states and the union is divided into the following three categories: The European Union has seven principal decision-making bodies, its institutions : the European Parliament , the European Council , the Council of the European Union , the European Commission ,
13952-612: The same year, the Schengen Agreement paved the way for the creation of open borders without passport controls between most member states and some non-member states. In 1986, the Single European Act was signed. Portugal and Spain joined in 1986.

Later that year, Slovenia adopted the euro, followed by Cyprus and Malta in 2008, Slovakia in 2009, Estonia in 2011, Latvia in 2014, and Lithuania in 2015. On 1 December 2009,
14208-449: The several peoples of the separate member states, rather than from a single undifferentiated whole. This is reflected in the fact that the member states remain the 'masters of the Treaties', retaining control over the allocation of competences to the union through constitutional change (thus retaining so-called Kompetenz-kompetenz ); in that they retain control of the use of armed force; they retain control of taxation; and in that they retain
14336-430: The signals are likely to arrive with a relative delay that is greater than the OFDM guard interval. Low power gap-filler transmitters can be added to an SFN as and when desired in order to improve reception quality, although the way SFNs have been implemented in the UK up to now they have tended to consist of higher power transmitters being installed at main transmitter sites in order to keep costs down. An ensemble has
14464-473: The states have agreed to act as one. EU policies aim to ensure the free movement of people, goods, services and capital within the internal market; enact legislation in justice and home affairs; and maintain common policies on trade , agriculture , fisheries and regional development . Passport controls have been abolished for travel within the Schengen Area . The eurozone is a group composed of
14592-422: The take up of DAB has been much slower than expected. As of 2023 , Norway is the first country to have implemented a national FM radio switch-off, with others to follow in the next years. In recent years, DAB has become the most popular radio listening platform in Norway, Switzerland and the UK , and has become a requirement for all new cars sold in the EU since 2021. The original version of DAB used
14720-493: The three communities, which were collectively referred to as the European Communities . Jean Rey presided over the first merged commission ( Rey Commission ). In 1973, the communities were enlarged to include Denmark (including Greenland), Ireland, and the United Kingdom .

14848-406: The traditional 270 kilohertz-wide analog channels, with capability of up to 300 kbit/s per station (pure digital mode). The full bandwidth of the hybrid mode approaches 400 kHz. The first generation DAB uses the MPEG-1 Audio Layer II (MP2) audio codec, which has less efficient compression than newer codecs. The typical bitrate for DAB stereo programs is only 128 kbit/s or less and as
14976-451: The transmission powers remained the same), would translate into people who currently experience reception difficulties on DAB receiving a much more robust signal with DAB+ transmissions. It also has a far steeper "digital cliff", and listening tests have shown that people prefer this when the signal strength is low compared to the shallower digital cliff on DAB. Immunity to fading and inter-symbol interference (caused by multipath propagation)
15104-509: The ubiquitous MP3 (MPEG-1 Audio Layer III). The newer DAB+ standard adopted the LC-AAC and HE-AAC , including its version 2 audio codecs, commonly known as AAC , AAC+ or aacPlus . AAC+ uses a modified discrete cosine transform (MDCT) algorithm, and is approximately three times more efficient than MP2, which means that broadcasters using DAB+ are able to provide far higher audio quality or far more stations than they could with DAB, or
15232-487: The union for foreign affairs and security policy (presently Josep Borrell ) also takes part in its meetings. Described by some as the union's "supreme political leadership", it is actively involved in the negotiation of treaty changes and defines the EU's policy agenda and strategies. Its leadership role involves solving disputes between member states and the institutions, and to resolving any political crises or disagreements over controversial issues and policies. It acts as

In 2012, the EU received the Nobel Peace Prize for having "contributed to the advancement of peace and reconciliation, democracy, and human rights in Europe". In 2013, Croatia became the 28th EU member. From the beginning of the 2010s, the cohesion of the European Union has been tested by several issues, including a debt crisis in some of
15488-408: The use of single-frequency networks ( SFN ), which means that a network of transmitters can provide coverage to a large area – up to the size of a country – where all transmitters use the same transmission frequency block. Transmitters that are part of an SFN need to be very accurately synchronised with other transmitters in the network, which requires the transmitters to use very accurate clocks. When
15616-478: The vast majority of receivers support DAB+. In the UK, DAB+ launched in January 2016 following a trial period starting September 2014. Ofcom published a consultation for a new national multiplex containing a mix of DAB and DAB+ services, with the intention of moving all services to DAB+ in the long term. In February 2016, the new national network Sound Digital launched with three DAB+ stations. In August 2021

This treaty was created in 1952 the European Coal and Steel Community (ECSC), which was built on the International Authority for the Ruhr , installed by
16384-788: Was to include the also proposed European Defence Community , an alternative to West Germany joining NATO which was established in 1949 under the Truman Doctrine . In 1954 the Modified Brussels Treaty transformed the Western Union into the Western European Union (WEU). West Germany eventually joined both the WEU and NATO in 1955, prompting the Soviet Union to form the Warsaw Pact in 1955 as an institutional framework for its military domination in
