/* Analogue to digital transition */
'''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 (electronics)|antenna (or aerial)]] instead of a [[satellite dish]] or [[cable]] connection.
The technology used is [[ATSC Standards|ATSC]] in North America, [[Integrated Services Digital Broadcasting|ISDB-T]] in Japan, [[DVB-T]] in Europe and Australia, 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.
[[Image:Digital broadcast standards.svg|thumb|400px|right|DTT broadcasting systems by country.]]
== Transmission ==
DTTV is transmitted on [[radio frequency|radio frequencies]] through the airwaves that are similar to standard [[analog television]], with the primary difference being the use of [[Multiplexing|multiplex]] transmitters to allow reception of multiple channels on a single frequency range (such as a [[ultra high frequency|UHF]] or [[very high frequency|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 [[Orthogonal frequency division modulation|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 [[sideband|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 ==
*Digital reception tends to be better overall, particularly with a weaker signal. With a good signal there is little perceptible difference, in fact analogue 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) is required.
*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 [[Antenna (radio)|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. This is quite common in the UK, see external links.

{{main|List of digital television deployments by country}}
=== Europe ===
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.
[[Digital terrestrial television in the United Kingdom|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 (United Kingdom)|Freeview]] platform in 2002. [[Top Up TV]], a ''lite'' pay DTT service, became available in 2004. Of all countries, the UK DTT has currently the highest penetration rate, in mid 2007 there were over 8 million subscribers. UK covers Northern Ireland DTT.
[[Digital terrestrial television in Ireland|In the Republic of Ireland]] [[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 separate broadcasting (BCI soon BAI) and spectrum regulator (ComReg)and the BCI were mandated to invite applications during 2008 under the [[Broadcasting (Amendment) Act 2007].] The Commission for Communications Regulation (ComReg) have issued to the BCI and RTÉ spectrum licenses in December 2007 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 will 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 radiowave space) will be public service with 98% Analogue Switchover (ASO) coverage required for Digital Aerial TV (DTT). The BAI 3 will have a 90% coverage requirement at ASO. 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 for 3 muxes which were presented in public on [[May 12]], [[2008]] in Dublin, (conditional on all 3 muxes) and will decide on the winning consortium around [[July 21]], [[2008]].[http://www.bci.i /news_information/press183.html]
A Houses of the Oireachtas Channel and Irish Film Channel Commissions will also be established under the Broadcasting Act 2008 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. [http://www.oireachtas.ie/documents/bills28/bills/2008/2908/b2908s.pdf].
The winning bidder will launch in 2009 according to all 3 submissions received.[http://www.bci.ie/DTT/licensing.html]. Standards chosen are MPEG4/H.264 and DVB-T. However with the UK Regulator mandating conversion of a Freeview multiplex to DVB-T2 PSB3 High Definition TV, it remains to be seen whether ComReg and the BCI will update their minimum specification similarly when consumer set top boxes and transmission equipment of this standard are likely to be available by launch time.
Portugal is expected to launch its DTT service in 2009 also with the public service broadcaster PTP providing FTA services in partnership with commercial broadcasters. Anacom regulates this area.
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 approximately 30 free-to-air national and regional TV and radio services.
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 networks. Switch-off of the analogue TV service started in September 2005 and finished on [[15 October]] [[2007]].
Finland launched DTT in 2001, and terminated analogue transmissions nationwide as the third country in the world on [[1 September]] [[2007]]. Finland has successfully launched a mixture of pay and free-to-air DTT services.
[[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]].
France's TNT ([[Télévision Numérique Terrestre]]) offers 18 free and 11 pay channels. A 70% DTT penetration rate is expected by March 2007. Free-to-view satellite services offering the same DTT offer are also expected to be ready by the end of 2006. FTA TNT uses MPEG2 while pay TNT in 2008 uses MPEG4/H.254 standard.
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.
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), nevertheless two member states (unspecified in the announcement) have expressed concerns that they would not be able to switch due to technical limitations.
=== North and South America ===
In the [[United States]] by no later than [[February 17]], [[2009]], all U.S. television broadcasts will be exclusively digital, under the Digital Television and Public Safety Act of 2005.<ref>Title III of the [[Deficit Reduction Act of 2005]], Pub. L.

The analog switch-off will render all non-digital televisions unable to receive most over-the-air television channels obsolete; 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.<ref>http://www.dtv2009.gov Digital Transition website Access date= 2007-12-31 </ref>
In Canada, analog switchoff is scheduled for [[August 31]], [[2011]].
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.
In Brazil, they chose a modified version of the Japanese ISDB-T standard, called [[SBTVD]].
[[Cuba]] has announced recently that in the current year could leave defined the norm to use. According to official sources of the MIC (Ministry of Computer science and Telecommunications) the Caribbean island would be decided between European format DVB or the DSM used by China. At the moment, Cuban specialists make tests in both formats but "analogical blackout" is far away.
[[Uruguay]] has chosen the European DVB.T standard.
=== Asia ===
==== Japan ====
<!-- Need further sub section for Japan, bcz no other country info. is active, and own ISDB system than other Asian countries. -->[[Japan]]ese [[Ministry of Internal Affairs and Communications]] and Dpa (The Association for Promotion of Digital Broadcasting-Japan) jointly set the [[Specification (technical standard)|specification]] and announced the guide line of "simplified DTT [[Antenna tuner|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 [[Analog television|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 (music)|dubbing]] of entire TV program with video and audio into [[DVD recorder]] and etc. by naming "Dubbing 10"<!-- Note: "Dubbing 10" is tentative writing or expression purpose only, not yet official English writing is announce by authority as of Jan., 2, 2008. Reading or pronunciation is "Dubbing ten" in Katakana is decided and started as formal usage. It is just announced Japanese language naming only by authority on Dec., 20, 2007. -->([[: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 [[12-hour clock|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 [[12-hour clock|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, recod and replay unit to operate with [[Personal computer]] on [[April 8]], [[2008]] . This [[add-on]] unit operates on [[Universal Serial Bus|USB]] or [[Peripheral Component Interconnect|PCI]] [[Bus (computing)|BUS]], and started to sell on reservation basis from late April and put on retail store in mid. May 2008<!--by IO DATA, BUFFALO, PIXELA & + -->.
[[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 (electronics)|Tuner]] with [[DVD recorder]] by end of March 2008, which was 27.8% in one year before, and expecting 100% by April 2011.
==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 Standards|ATSC]] or [[ISDB-T]].
*Interactive: System used for interactive services, such as [[Multimedia Home Platform|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 the UK which uses MPEG-2 for standard content but MPEG-4 for some HD broadcasts.
