High-definition television transition

Last updated

The transition to high-definition television is a process by which standard-definition (SD) television signals are upgraded to a high-definition (HD) format. [1] In this process, channels usually either simulcast their HD signals alongside the existing SD signals or broadcast exclusively in HD. The transition to the latter is often referred to as the standard-definition television switch-off.

Contents

In most territories around the world, the complete shutdown of the lower-resolution signals has not yet begun or is still in its early stages, notably in the many countries that are still undergoing the analogue switch-off.

In territories and services where SD signals have already ceased, television sets that do not support terrestrial HD signals are required to be replaced or equipped with set-top boxes compatible with HD signals. [1] [2] [3] In some cases, this switch-off has led to a high demand for new set-top boxes and TV sets, resulting in shortages. [4]

Transition by country or territory

Transitions to HD and SD switch-offs completed

Asia

  • Flag of Brunei.svg  Brunei: Radio Television Brunei began incoporating HD channels by 2010 [5] and fully migrated all its channels to HD digital service on 1 January 2018. [6]
  • Flag of Singapore.svg  Singapore: On 10 June 2006, Singapore became the first country in Southeast Asia to begin trials of high definition television service, involving MediaCorp and cable provider StarHub. The beginning of the trials coincided with the 2006 FIFA World Cup, with StarHub launching HD service for 1,000 participants. It would carry all matches from the tournament in HD, and then two HD trial channels afterward. MediaCorp would launch its terrestrial trial service just over a week later 18 June, carrying a part-time service in prime time with a mix of original and acquired HD programming and films (some of which simulcast from Channel 5), with its inaugural broadcast featuring the film The Lord of the Rings: The Two Towers [7] [8] . On 11 November 2007, the trial service was relaunched as HD5, an HD simulcast of Channel 5. MediaCorp also tested interactive television. In June 2012, after a trial conducted by Mediacorp and StarHub in Ang Mo Kio and Bedok, the Media Development Authority officially announced that Singapore would adopt the DVB-T2 standard, with Mediacorp aiming to make all seven of its free-to-air channels available in digital by the end of 2013, with Channel 5, 8, Suria, and Vasantham also being in high definition. The member countries of the Association of Southeast Asian Nations (ASEAN) agreed to complete their transitions by 2020.

As of April 2024, All the Singaporean native channels are now in high definition.

Following the switchover to DVB-T2 on 8 March 2022, [16] the HD versions of Italian channels were moved to the top of the list, while the SD versions were positioned from 500 onwards. [17] Channels still broadcasting in SD began to be shut down on 21 December 2022, [18] with the total closure taking place on 1 January 2023, [19] [2] although many channels still carry the HD identifier in their logos.

[22] Regarding private broadcasters, the first HD simulcasts were launched by Telecinco on 20 September 2010, [23] followed by Antena 3 on 28 September [24] and La Sexta on 1 November. In April 2016, the first channels with just a high-definition feed began to appear: Atreseries and BeMad TV, as well as the public broadcasts of Real Madrid TV. Originally, the Spanish government planned to require all standard definition broadcasts to cease on 1 January 2023, along with Italy, but the decision was postponed. [25] On 17 January 2023, a decree issued by the Ministry of Digital Transformation set the final closing date at 14 February 2024. [26] [27] The first channel to shut down its SD broadcasts was Extremaduran channel Canal Extremadura on 15 January 2024. It was followed by Canarian Televisión Canaria and all the Catalan channels from Televisió de Catalunya, which did so the next day. [28] [29] [3] TVE closed all its SD channels on 6 February, coinciding with the launch of its 4K channel, TVE UHD  [ es ], [30] [31] while Telemadrid and the Basque channels from ETB did the switch-off on 8 February. Most regional channels carried out the switch-off on 12 February, with the exception of La 7 in Murcia, which did so on the 13th, just one day before the full closure of SD signals. [29] Most private channels cut out SD signals on 14 February. SD-only channels, such as Boing, Disney Channel, DMAX and DKiss, switched their feeds to HD. [32]
    • Flag of Catalonia.svg  Catalonia: The HD version of flagship public channel TV3 was launched on 23 April 2007, being fully implemented in March 2011. [33] On 30 October 2023, channels 3/24, SX3, Esport3 and El 33 started broadcasting in HD online, through the 3Cat platform. In January 2024, Televisió de Catalunya announced the shutdown of all SD signals would take place on 16 January, with the SD version of TV3 being shut down and all the other channels automatically switching their feeds into HD. [34] [35] [36] [28] The Balearic channel IB3, which until then had only broadcast in poor SD quality due to the limited space left in the multiplex, also made the switch to HD on the same day. [3] The switch-off of SD television caused queues and shortages of adapters and television sets across Catalonia. [37]
