Digital television transition in India began in 2010.
31 March 2022 marked an important milestone in the history of India's broadcasting landscape as the national broadcaster, Doordarshan, phased out the last set of obsolete analogue terrestrial TV transmitters.
The Television Networks (Regulation) Amendment Act, 2011 has made digital satellite and cable television transition mandatory in four phases. It was implemented after multiple extensions of analogue switch-off dates. The broadcasters, Multi System Operators (MSOs), and Local Cable Operators (LCOs) were ordered by the Ministry of Information and Broadcasting to end analogue transmission completely on 31 March 2017.

| Phase | Area | Regulatory direction for Analogue Switch-off | Actual Implementation Date |
|---|---|---|---|
| I | 4 metros – Mumbai, Delhi, Kolkata, Chennai | 30 June 2012 | 31 October 2012 (Delhi and Mumbai); 15 February 2013 (Kolkata); 17 August 2017 (Chennai) [5] |
| II | 38 cities with a population of more than 1 million | 31 March 2013 | 1 January 2014 |
| III | All other urban areas across India with a municipality | 30 September 2014 | 31 January 2017 [6] [7] |
| IV | Rest of India | 31 December 2014 | 31 March 2017 [1] |
The Telecom Regulatory Authority of India had set the deadlines for the completion of the transition to digital-terrestrial TV Phase I (Metro cities) by 31 December 2019, Phase II (cities having a population of more than one million) by 31 December 2021, and Phase III (the rest of India) by 31 December 2023.
Digital Video Broadcasting (DVB) is a set of international open standards for digital television. DVB standards are maintained by the DVB Project, an international industry consortium, and are published by a Joint Technical Committee (JTC) of the European Telecommunications Standards Institute (ETSI), European Committee for Electrotechnical Standardization (CENELEC) and European Broadcasting Union (EBU).
Terrestrial television or over-the-air television (OTA) is a type of television broadcasting in which the content is transmitted via radio waves from the terrestrial (Earth-based) transmitter of a TV station to a TV receiver having an antenna. The term terrestrial is more common in Europe and Latin America, while in Canada and the United States it is called over-the-air or simply broadcast. This type of TV broadcast is distinguished from newer technologies, such as satellite television, in which the signal is transmitted to the receiver from an overhead satellite; cable television, in which the signal is carried to the receiver through a cable; and Internet Protocol television, in which the signal is received over an Internet stream or on a network utilizing the Internet Protocol. Terrestrial television stations broadcast on television channels with frequencies between about 52 and 600 MHz in the VHF and UHF bands. Since radio waves in these bands travel by line of sight, reception is generally limited by the visual horizon to distances of 64–97 kilometres (40–60 mi), although under better conditions and with tropospheric ducting, signals can sometimes be received hundreds of kilometers distant.
DVB-T, short for Digital Video Broadcasting – Terrestrial, is the DVB European-based consortium standard for the broadcast transmission of digital terrestrial television that was first published in 1997 and first broadcast in Singapore in February, 1998. This system transmits compressed digital audio, digital video and other data in an MPEG transport stream, using coded orthogonal frequency-division multiplexing modulation. It is also the format widely used worldwide for Electronic News Gathering for transmission of video and audio from a mobile newsgathering vehicle to a central receive point. It is also used in the US by Amateur television operators.
Television in Hong Kong is primarily in Cantonese and English. It is delivered through analogue and digital terrestrial, cable, IPTV, and the Internet. Satellite TV is not common, although many housing estates have dishes and re-distribute a limited number of free channels through coaxial cables. The dominant broadcaster is TVB, ViuTV and HOY TV.
Digital terrestrial television is a technology for terrestrial television where television stations broadcast television content in a digital format. DTTV is a major technological advance over analog television, and has largely replaced analog television broadcast, which had been in common use since the middle of the 20th century. Test broadcasts began in 1998 with the changeover to DTTV, also known as the Analog Switchoff (ASO) or Digital Switchover (DSO), which began in 2006 and is now complete in many countries. The advantages of digital terrestrial television are similar to those obtained by digitizing platforms such as cable TV, satellite, and telecommunications: more efficient use of radio spectrum bandwidth, provision of more television channels than analog, better quality images, and potentially lower operating costs for broadcasters.
PALplus is an analogue television broadcasting system aimed to improve and enhance the PAL format by allowing 16:9 aspect ratio broadcasts, while remaining compatible with existing television receivers, defined by International Telecommunication Union (ITU) recommendation BT.1197-1. Introduced in 1993, it followed experiences with the HD-MAC and D2-MAC, hybrid analogue-digital widescreen formats that were incompatible with PAL receivers. It was developed at the University of Dortmund in Germany, in cooperation with German terrestrial broadcasters and European and Japanese manufacturers. The system had some adoption across Europe during the late 1990s and helped introduce widescreen TVs in the market, but never became mainstream.
The television industry in India is very diverse and produces thousands of programs in many Indian languages. More than half of all Indian households own a television. As of 2016, the country had over 900 channels of which 184 were pay channels. National channels operate in Hindi and English, in addition to channels in several other languages including Telugu, Tamil, Kannada, Malayalam, Bengali, Marathi, Odia, Punjabi, Assamese, Gujarati, Urdu, Bhojpuri, Kashmiri, Konkani and Haryanvi, among others. The Hindi, Telugu and Tamil language television industries are by far the largest television industries in India.
Malaysian television broadcasting was introduced on 28 December 1963. Colour television was introduced on 28 December 1978. Full-time colour transmissions were officially inaugurated on New Year's Day 1982. There are currently 16 national free-to-air terrestrial television channels in Malaysia and 3 national pay subscription television operators in Malaysia.
Analogue television in the United Kingdom includes terrestrial, satellite and cable services that were broadcast using analogue television signals. Following the termination of Virgin Media's analogue cable television service in Milton Keynes in November 2013, all television in the United Kingdom is broadcast in digital only.
Digital terrestrial television in Australia commenced on 1 January 2001 in Sydney, Melbourne, Brisbane, Adelaide and Perth using DVB-T standards. The phase out of analogue PAL transmissions began on 30 June 2010 and was completed by 10 December 2013.
DTMB is the digital TV standard for mobile and fixed devices, developed in the People's Republic of China. It is used there and in both of their special administrative regions, and also in Cambodia, the Comoros, Cuba, East Timor, Laos, Vietnam, and Pakistan. In Pakistan, as part of the China–Pakistan Economic Corridor Project, ZTE Corporation will provide Pakistan Television Corporation collaboration across several digital terrestrial television technologies, staff training, and content creation, including partnerships with Chinese multinational companies in multiple areas, such as television sets and set top boxes, as a form of "International Cooperation".
DVB-T2 is an abbreviation for "Digital Video Broadcasting – Second Generation Terrestrial"; it is the extension of the television standard DVB-T, issued by the consortium DVB, devised for the broadcast transmission of digital terrestrial television. DVB has been standardized by ETSI.
There are four major forms of digital television (DTV) broadcast in the United Kingdom: a direct-to-home satellite service from the Astra 28.2°E satellites provided by Sky UK, a cable television service provided by Virgin Media ; a free-to-air satellite service called Freesat; and a free-to-air digital terrestrial service called Freeview. In addition, an IPTV system known as BT TV is provided by BT. Individual access methods vary throughout the country. 77% of the United Kingdom has access to HDTV via terrestrial digital television. Satellite is the only source of HDTV broadcast available for the remaining 23%.
Digital terrestrial television in Canada is transmitted using the ATSC standard. Because Canada and the U.S. use the same standard and frequencies for channels, people near the Canada–United States border can watch digital television programming from television stations in either country where available. The ATSC standards are also used in Mexico, the Dominican Republic, Suriname, and South Korea.
Digital television in the United States is available via digital terrestrial television (DTT), digital cable, satellite television, and IPTV providers.
In Malaysia, digital television broadcasts, DTV or DHD, can be received via cable, internet, satellite, or via free over-the-air (OTA) digital terrestrial television - much like analogue television broadcasts have been. It began in the mid-1990s with the introduction of the Astro satellite television service, now followed by new paid television services in the 2000s, as well as the digitalisation of over-the-air TV which was expected to be complete by the mid-2010s before being shelved. This article discusses various platforms where DTV is applied in Malaysia, including Digital Video Broadcasting (DVB) and Internet Protocol Television (IPTV). Following its successful nationwide digital transition on 31 October 2019, the country became the third in Southeast Asia with digital broadcasts after neighbouring Brunei and Singapore.
Television in Belgium was introduced in 1953 and began with one channel each in Dutch and French. The country is heavily cabled, with 93% of households watching television through cable as of 2003.
Digitenne is the Dutch digital terrestrial television platform. It is owned by KPN. Digitenne uses the DVB-T2 standard. The national public television channels NPO 1, NPO 2, NPO 3 and the regional public television channels are free-to-air. For all other television channels a subscription is required.
The digital television transition, also called the digital switchover (DSO), the analogue switch/sign-off (ASO), the digital migration, or the analogue shutdown, is the process in which older analogue television broadcasting technology is converted to and replaced by digital television. Conducted by individual nations on different schedules, this primarily involves the conversion of analogue terrestrial television broadcasting infrastructure to digital terrestrial (DTT), a major benefit being extra frequencies on the radio spectrum and lower broadcasting costs, as well as improved viewing qualities for consumers.
