Digital Terrestrial Television (DTTV or DTT) is an implementation of digital technology to provide a greater number of channels and/or better quality of picture and sound using aerial broadcasts to a conventional antenna (or aerial) instead of a satellite dish or cable connection. The technology used is ATSC in North America and South Korea, ISDB-T in Japan, Brazil and Peru, DVB-T in Europe, Australia, New Zealand, Colombia, Uruguay and some countries of Africa, and DMB-T/H in China (including Hong Kong); the rest of the world remaining mostly undecided. ISDB-T is very similar to DVB-T and can share front-end receiver and demodulator components.
Transmission
DTTV is transmitted on radio frequencies through the airwaves that are similar to standard analog television, with the primary difference being the use of multiplex transmitters to allow reception of multiple channels on a single frequency range (such as a UHF or VHF channel).
The amount of data that can be transmitted (and therefore the number of channels) is directly affected by the modulation method of the channel. The modulation method in DVB-T is COFDM with either 64 or 16 state Quadrature Amplitude Modulation (QAM). In general a 64QAM channel is capable of transmitting a greater bitrate, but is more susceptible to interference. 16 and 64QAM constellations can be combined in a single multiplex, providing a controllable degradation for more important programme streams. This is called hierarchical modulation.
New developments in compression have resulted in the MPEG-4/AVC standard which will enable two high definition services to be coded into a 24 Mbit/s European terrestrial transmission channel.
The DVB-T standard is not used for terrestrial digital television in North America. Instead, the ATSC standard calls for 8VSB modulation, which has similar characteristics to the vestigial sideband modulation used for analogue television. This provides considerably more immunity to interference, but is not immune - as DVB-T is - to multipath distortion and also does not provide for single-frequency network operation (which is in any case not relevant in the United States).
Both systems use the MPEG-2 transport stream and video codec; they differ significantly in how related services (such as multichannel audio, captions, and program guides) are encoded.
Advantages and disadvantages
Advantages:
- Digital reception tends to be better overall, particularly with a good signal. With a weaker signal there is little perceptible difference, in fact analog can be better.
- It is easier to obtain the optimum digital picture than the optimum analogue picture.
- Many more channels can fit on the digital transmission.
- Interactive (red button) services can be provided.
Disadvantages:
- New equipment (Set-top box) may be required.
- Increased electricity consumption by the digital receiving equipment.
- An upgraded antenna installation may be required.
- Analog requires lower signal strength to get a watchable picture. By extension, digital does not degrade as gracefully as analog.
- Switching channels is slower because of the time delays in decoding digital signals.
Reception
DTTV is received via a digital set-top box, or integrated receiving device, that decodes the signal received via a standard aerial antenna. However, due to frequency planning issues, an aerial with a different group (usually a wideband) may be required if the DTTV multiplexes lie outside the bandwidth of the originally installed aerial.[clarification needed] This is quite common in the UK, see external links.
DTT Around the world
Europe
United Kingdom
The United Kingdom (1998), Sweden (1999) and Spain (2000) were the first to launch DTT with platforms heavily reliant on pay television. All platforms experienced many starter problems, in particular the British and Spanish platforms which failed financially. Nevertheless, Boxer, the Swedish pay platform which started in October 1999, proved to be very successful.
DTT in the United Kingdom was launched in November 1998 as a primarily subscription service branded as ONdigital, a joint venture between Granada Television and Carlton Communications, with only a few channels being available free to air. ONdigital soon ran into financial difficulties with subscriber numbers below expectations, and in order to attempt to reverse their fortunes, it was decided that the ITV and ONdigital brands should align, and the service was rebranded ITV Digital in 2001. Despite an expensive advertising campaign, ITV Digital struggled to attract sufficient new subscribers and in 2002 closed the service. After commercial failure of the Pay TV proposition it was relaunched as the free-to-air Freeview platform in 2002. Top Up TV, a lite pay DTT service, became available in 2004.
DSO has begun in the UK in some areas and will begin soon in others and over the next there years will be completed in all by the end of 2012. One multiplex for public service broadcasters has been given freed up and given over to HD on DTT and some areas will be able to receive Freeview HD in advance of digital switchover using the new 2nd generation DVB-T2 and MPEG4 set top boxes according to Freeview.[1][2]
Republic of Ireland
In the Republic of Ireland the establishment of DTT has been somewhat problematic. Initially, in the mid-1990s It's TV was the sole applicant for a digital terrestrial television license under the provisions of the Irish Broadcasting Act 2001 which also established Telífís na Gaeilge, now TG4. It proposed a triple play deployment with Broadband, TV and Digital Radio services. However, following financial difficulties with other DTT deployments, most particularly in the neighbouring UK and in Spain and Portugal, it's TV failed to get its license conditions varied or to get a time extension to securing funding and its license was eventually withdrawn for non performance.
Under subsequent legislation in May 2007, RTÉ and the spectrum regulator (ComReg)and the broadcasting regulator BCI (soon BAI) were mandated to invite applications during 2008 under the Broadcasting (Amendment) Act 2007and RTÉ and the BCI received licenses from ComReg and the BCI advertised and invited multiplex submissions by May 2, 2008. RTÉ Networks is required to broadcast in digital terrestrial TV (aerial TV) under the new Act and received an automatic license through the RTÉ Authority (soon the Broadcasting Authority of Ireland in its place) and will upgrade part of its network over a 5 year period.It will also make this network available to the commercial multiplex winner for rental of capacity. 1 Mux (group of channel radio wave space) will be provide the services of the public service broadcaster have a 98% population coverage. The other three multiplexes will have a 90% population coverage. Following ASO 1 addition PSB mux and 1 or more commercial muxes will be made available for DTT, mobile television and other services.
The BCI (soon BAI) received 3 conditional applications to operate the 3 muxes which were presented in public on May 12, 2008. It decided in principle to allocate the license to Boxer DTT Ltd, a consortium made up of the Swedish pay-DTT operator Boxer and the media group Communicorp at its board meeting on July 21, 2008.[3] On 20 April 2009, the BCI revealed that OneVision had been the second placed applicant and that following Boxer's withdrawal, it intended to ascertain whether it was still interested in operating the DTT multiplexes. [4]
A Houses of the Oireachtas Channel Oireachtas TV (reportedly shelved in December 2008) and Irish Film Channel (may be shelved) Commissions will also be established under the Broadcasting Act 2009 (soon to be enacted) as new public service broadcasters. The Broadcasting Authority of Ireland will replace the Broadcasting Complaints Commission, the Broadcasting Commission of Ireland and the RTÉ Authority and include Awards and Advisory Committees once the Broadcasting Bill 2008 is enacted as the Broadcasting Act 2009.[5]
Boxer DTT Ireland, tentative start date was January in 2009 in Ireland.[6] Standards chosen are MPEG4/H.264 and DVB-T. Boxer TV Access has a 50% holding in Boxer Ireland.It remains to be seen if Onevision as second placed applicant or the third will take up the pay DTT contract with the BCI that would also facilitate joint co-ordinated DTT Free-to-air and commercial DTT launches in time.[7] A DTT Information Campaign was announced by the Department of Communications, Energy & Natural Resources Irish Government Department to launch in March 2009 ahead of the September 2009 launch of Irish DTT.[8] As May 2009, the information campaign has not launched and has been postponed until late autumn 2009 to be undertaken by the BCI (BAI) with support of the Department. OneVision has been offered the opportunity to operate the pay-service pay DTT. It is expected that this service will launch late 2009 depending on whether negotiations conclude successfully or possibly early 2010.
The Netherlands
The Netherlands launched its DTT service 23 April 2003, and terminated analogue transmissions nationwide on 11 December 2006. KPN own Digitenne which provides pay DTT services. DTT is now proving to be an able competitor to cable in a highly cable dominated country.[9] It also provides a mobile broadcast DVB-H service as well as an IPTV service, with DTT the most popular of its products.[10]
Portugal
Portugal launched its DTT service on April 29 2009 available to around 20% of the Portuguese population and Portugal Telecom expects to reach 80% of the population by the end of the 2009. Airplus TV Portugal that was set up to compete for a licence to manage Portugal’s pay-TV DTT multiplexes, will dissolve as the licence as it didn't get the license and a Portuguese court ruled not to suspend the process for the awarding of a licence to Portugal Telecom, based on a complaint submitted by Airplus TV Portugal. The start of the pay-TV multiplexes will take place later in the year.[11]
Spain
In Spain most multiplexes closed after the failure of Quiero TV, the country's original pay DTT platform. DTT was relaunched on 30 November 2005, with 20 free-to-air national TV services as well as numerous regional and local services. Nearly 11 million DTT receivers had been sold as of July 2008. Positive approval for pay DTT services have reportely been given by Spain’s Ministry of Industry in a suprise move on (June 17) of the Advisory Council on Telecommunications and the Information Society (Catsi). IT will now be included in a Royal Decree. A number of leading Spanish media players including Sogecable, Telefónica, Ono, Orange and Vodafone have apparently criticised that as according to Prisa, Sogecable’s owner, “it caps a series of policy changes that benefits only a few audiovisual operators, those of terrestrial TV, to the detriment of satellite operators, cable and DSL.” There may be appeals lodged against the government’s decision. [12]
Sweden
In Sweden, DTT was launched in 1999 solely as a paid service. Today (2007) there are 38 channels in 5 MUXs. 11 of those are free-to-air channels from a number of different broadcasters. Switch-off of the analogue TV service started in September 2005 and finished on 15 October 2007. Boxer began the deployment of MPEG-4 receivers to new subscribers. Over the next six years from 2008 Sweden will gradually migrate from MPEG-2 visual coding to using MPEG-4, H.264. The Swedish Radio and TV Authority (RTVV) recently announced eight new national channels that will broadcast in the MPEG-4 format. From April 1 2008 Boxer is also responsible for approving devices to use on the network, will no longer accept MPEG-2 receivers for test and approval.Set Top Boxes must be backward compatible so that they can decode both MPEG-2 and MPEG-4 coded transmissions. [13]
Finland
Finland launched DTT in 2001, and terminated analogue transmissions nationwide on 1 September 2007. Finland has successfully launched a mixture of pay and free-to-air DTT services. Digita operates the DTT and Mobile Terrestrial networks and rents capacity to broadcasters on its network on a neutral market basis. Digita is owned by TDF (France).[14] ,[15].The pay-DTT service provider Boxer has acquired a majority stake in the leading Finnish pay DTT operator PlusTV which offers a number of commercial channels for a subscription. It started in October 2006. Boxer already provides pay-DTT services in Sweden and Denmark.[16]
Germany
Germany launched a free-to-air platform region-by-region, starting in Berlin in November 2002. The analogue broadcasts are planned to cease soon after digital transmissions are started. Berlin became completely digital on 4 August 2003 with other regions completing between then and 2008. Digital switchover has been completed throughout Germany as of the 2nd December 2008 and services are now available to 100% of the population following the update of infill for the remaining 10% of transmitters by Media Broadcast who set up broadcast antennas at 79 transmission sites and installed 283 new transmitter stations. More services are to be launched on DTT and some pay DTT channels are or have been launched in various areas such as Stuttgart and soon Leipzig.[17]
France
France's TNT (Télévision Numérique Terrestre) offers 18 free and 11 pay channels. An 89% DTT penetration rate is expected by December 2008. Free-to-view satellite services offering the same DTT offer were made available in June 2007. FTA TNT uses MPEG2 while pay TNT in 2008 uses the MPEG4 AVC/H.264 compression format.
Since 30-10-2008 France has four free HD channel (TF1 HD,France2 HD,Arte HD,M6 HD) and one pay TNT HD chanel (Canal+ HD) on TNT using the MPEG4 AVC/H.264 compression format. Following the huge success of the free TNT some pay channels now want to become free channels. ASO by 30th November 2011.
The Prime Minister François Fillon has confirmed that the final analogue switch-off date will be the 30th November 2011.[18] DTT coverage must reach 91% of a given department before analogue transmissions can be switched off.CSA announced a call to tender for more local DTT licences on June 15th 2009 and 66 new DTT sites went up since May 2009 to expand coverage to cover low population areas. [19][20]
Freesat began broadcasts from the Eutelsat Atlantic Bird 3 satellite from June 2009 as Fransat, providing for those unable to receive DTT signals for terrain reasons in preparation for ASO in 2011. Eighteen channels will be broadcast initially and although free to watch, viewers will need to buy an Set top box with smart card for €99 euros according to DVB.org article.[21]
Bulgaria
Bulgaria launched a free-to-air platform on Sofia region, starting in November 2004. Standards chosen are DVB-T/DVB-T2 and MPEG4/H.264 compression format.The Communications Regulatory Commission (CRC) has said that it received 6 bids for the licence to build and operate Bulgaria’s two nationwide DTT networks. A second licence tender for the operation of 3 DTT multiplexes was open until 27 May 2009.[22][23]Following the closing of this process, Hannu Pro, part of Silicon Group, and with Baltic Operations has secured the license to operate three DTT multiplexes in Bulgaria by the country’s Communications Regulatory Commission (CRC)Bulgaria is aiming to complete the transition to digital broadcasting in December 2012.[24]
Romania
In Romania, broadcasting regulations have been amended so that DTT service providers have only a single licence rather than the two previously required by the National Audiovisual Council (CNA).DTT services are set to launch in 2010 using the MPEG-4 (H.264 AVC) compression format.
The Ministry of Communications (MCSI) estimates that that 49% of Romania’s 7.5 million households get TV from cable and 27% from DTH services in Romania while terrestrial TV is used by 18% of the TV households. 6% are reported as not able to receive TV transmissions. Subsidies may be offered for those below a certain income to assist switchover for them.[25] Switchover is scheduled for January 2012.[26]
Luxembourg
Luxembourg launched DTT services in April 2006. The national service launched in June 2006. On 1 September 2006, Luxembourg became the first European country to transition completely to DTT.Luxe TV, a niche theme based station, will soon begin broadcasting on the Luxembourg DTT platform, transmitted from the Dudelange transmitter.The aim is to reach audiences in some parts of Germany as well as in Luxembourg.[27][28]
Poland
DTT launch in Poland is scheduled for Autumn 2009. Regulatory disagreements delayed its tender and approach until resolved recently and the multiplexs available for DTT were reduced to 3 and the 2nd is to licensed in the Autumn of 2009. The reduction from 5 to 3 enable mobile TV and broadband to get more spectrum allocation. Muxes 2 and 3 may therefore have limited coverage until ASO. Polsat, TVN, TV4 and TV Puls have officially applied to reserve space on the countries first multiplex set to start in September. Wirtualne Media is given as the source of the story.The public broadcaster’s three main channels TVP1, TVP2 and TVP Info have already been allocated capacity on the multiplex.
Poland is to switch off analogue transmissions by 31st July 2013. A mobile TV license has also been awarded in Poland to Info TV FM to use DVB-H standard. [29]
European Union
The EU recommended in December 2005 that its Member States cease all analogue television transmissions by the year 2012. Some EU member states decided to complete the transition as early as 2007 (e.g. Finland).[30][31] While Poland and Bulgaria had been looking towards 2015, Poland has now decided for June 2013 and Bulgaria 2012. See section on Poland above. It looks likely that ASO will be completed in Europe in 2013 though small hilly underpopulated isolated terrain areas will be awaiting DTT rollout beyond that date. [32]
North and South America
United States
In the United States by no later than June 12, 2009, all full power U.S. television broadcasts became exclusively digital, under the Digital Television and Public Safety Act of 2005.[33][34] Furthermore, starting March 1, 2007, new television sets that receive signals over-the-air, including pocket sized portable televisions, must include ATSC digital tuners for digital broadcasts.[35] Prior to June 12, most U.S. broadcasters were transmitting in both analog and digital formats; a few were digital-only. Most U.S. stations were not permitted to shut down their analog transmissions prior to February 16, 2009, unless doing so is required in order to complete work on a station's permanent digital facilities.[36] In 2009, the FCC will finish auctioning channels 52–59 (the lower half of the 700 MHz band) for other communications services,[37] completing the reallocation of broadcast channels 52–69 that began in the late 1990s.
The analog switch-off will render all non-digital televisions unable to receive most over-the-air television channels; however, low-power television stations and cable TV systems are not required to convert to digital until 2011 or later. Beginning January 1, 2008, consumers may request coupons to help cover most of the cost of these converters by calling a toll free number or via a website.[38] Some television stations have also been licensed to operate "nightlights", analog signals which consist only of a brief repeated announcement advising remaining analog viewers how to switch to digital reception.
Canada
In Canada, analog switchoff is scheduled for August 31, 2011. Most network stations are already broadcasting high-definition digital signals in Toronto, with partial network digital coverage in Ottawa, Montreal and Vancouver. In Mexico, digital signals are on-air in the largest markets, with more cities to be added in descending order of size until full national coverage is reached in 2021; at that point analogue broadcasts will end.
El Salvador
In El Salvador chose the American ATSC standard on March 11, 2009.
Nicaragua
In Nicaragua will be chosen the chinese standard DMB-T/H.
Venezuela
In Venezuela, tests are being performed with full deployment to start 2008-2009. DTT will coexist with analog standard television for some time, until full deployment of the system on a nationwide level is accomplished.
Brazil
In Brazil, they chose a modified version of the Japanese ISDB-T standard, called ISDB-Tb (or SBTVD) in June, 2006. Digital broadcast started in December 2, 2007 in São Paulo and now it is under expansion all over the country (as of April 25, 2009, only metro areas of São Paulo, Rio de Janeiro, Belo Horizonte, Brasilia, Goiânia, Curitiba, Porto Alegre, Salvador, Campinas and Cuiabá have digital terrestrial broadcasting). Analog shut-off is scheduled for June 29, 2016.
Cuba
Cuba has announced recently that it will decide on the norm to use, within the current year. According to official sources of the MIC (Ministry of Computer science and Telecommunications) the Caribbean island is deciding between the DMB-T/H format used by China. At the moment, Cuban specialists are performing tests in both formats but an "analogical blackout" is far away.
Uruguay
Uruguay has chosen the European DVB-T standard.[39]
Colombia
Colombia has chosen the European DVB-T standard on August 28,2008 and began digital broadcasting in that month. It is expected that by year end 2009 some 42% of the Colombian population will receive digital TV coverage.[40] Initially only the public service broadcasters will use the DTT platform but the nations private channels are also expected to join in the next few months.[41]
Ecuador
Ecuador is currently assessing which standard to use (2008-2009)[42].
Peru
Peru has chosen on April 23, 2009 the Brazilian modified version of the Japanese standard ISDB-T
Panama
Panama has chosen the European DVB-T standard on May 12, 2009[43]
Asia
Japan
Japanese Ministry of Internal Affairs and Communications and Dpa (The Association for Promotion of Digital Broadcasting-Japan) jointly set the specification and announced the guide line of "simplified DTT tuner" with price under 5,000 Japanese yen on December 25, 2007. MIAC officially solicit manufactures to put it on the market by end of March 2010 (end of fiscal year 2009). MIAC is estimating 14 million, at maximum, set of traditional non-digital TV remains and needs the "simplified DTT tuner" to be adapted even after complete transition to DTT after July 2011, and is aiming to avoid disposal of large number of useless TV sets without such a tuner at one time.
December 20, 2007, Japan Electronics and Information Technology Industries Association set the rule (of copy control) for DTT broadcasting allows consumers up to 10 time of dubbing of entire TV program with video and audio into DVD recorder and etc. by naming "Dubbing 10"(ja:ダビング10) (actually up to 9 times of copy then 1 time or last time of move) and is supposed to start the broadcasting with "Dubbing 10" at about 4:00 a.m. on June 2, 2008, but postponed, that settled after long talks with Japanese Society for Rights of Authors, Composers and Publishers, then confirmed to start about 4:00 a.m. on July 4, 2008. The manufacture for DVD recorder and associated DTT recorder will make unit conforming "Dubbing 10" rule and some manufacture shall release the down loading subprogram to up date recorder's internal software for existing user.
April 3, 2008, Dpa (The Association for Promotion of Digital Broadcasting-Japan) announced that total 32.71 million of DTT (ISDB-T) receiving TV sets (except 1seg receiver) are installed in Japan as of end of March 2008. Dpa also announced the guide line documentation to manufacture who make the DTT receive, record and replay unit to operate with Personal computer on April 8, 2008 . This add-on unit operates on USB or PCI BUS, and started to sell on reservation basis from late April and put on retail store in mid. May 2008.
May 8, 2008, the Ministry of Internal Affairs and Communications announced that 43.7% of homes have DTT (ISDB-T) receiving TV and/or Tuner with DVD recorder by end of March 2008, which was 27.8% in one year before, and expecting 100% by April 2011.
April 27, 2009, National Association of Commercial Broadcasters in Japan (NAB) revealed its official mascot, Chidejika, to replace Tuyoshi Kusanagi as the face of NBA after he was arrested on suspicion of public indecency.
Analogue to digital transition
The broadcasting of digital terrestrial transmissions has led to many countries planning to phase out existing analogue broadcasts. This table shows the launches of DTT and the closing down of analogue television in several countries.
- Official launch: The official launch date of digital terrestrial television in the country, not the start for trial broadcasts.
- Start of closedown: The date for the first major closedown of analogue transmitters.
- End of closedown: The date when analogue television is definitely closed down.
- System: Transmission system, e. g. DVB-T, ATSC or ISDB-T.
- Interactive: System used for interactive services, such as MHP and MHEG-5.
- Compression: Video compression standard used. Most systems use MPEG-2, but the more efficient H.264/MPEG-4 AVC has become increasingly popular among networks launching later on. Some countries use both MPEG-2 and H.264, for example France which uses MPEG-2 for standard definition free content but MPEG-4 for HD broadcasts and pay services.
