ERT B (formerly the second multiplexer of ERT Digital) is the second multiplexer of ERT. It started broadcasting in 2010. During 2010-2011, it broadcast its channels exclusively on the DVB-T / MPEG-4 system. In the beginning, it included only the then three main channels of ERT (ET1, NET and ET3) and the Parliament channel.
Due to a capacity problem, on April 27, 2011, the Parliament channel was moved from the first multiplexer to the second, to give space to the first to broadcast ERT HD, until June 11, 2013, when ERT was closed by a government decision.
As of June 11, 2015, when ERT reopened, it broadcasts only the following: four new public main channels (ERT1, ERT2, ERT3 and ERT HD) while the Parliament channel returned, respectively, from the second multiplexer to the first.
As of February 1, 2019, ERT B, covers 98% of the country's population, from 156 broadcasting centers, which were previously covered in many parts of the country through the 4th frequency of Digea, due to the absence of transponders. On February 9, 2019, ERT HD was renamed ERT Sports HD, which continued to be broadcast in High Definition 1080i resolution, and respectively, all sports events, of public television, were transferred to the station program.
Its channels are broadcast exclusively on MPEG-4, except for ERT1 HD, which on December 1, 2020, replaced ERT Sports, which was broadcast in High Definition 1080i resolution, while until the end of 2021, ERT will broadcast from 200 broadcasting centers.
It broadcasts only the three main public television stations of ERT S.A., the television station of the Hellenic Parliament, as well as five public radio stations, the worldwide Voice of Greece and the newly established Zeppelin 106.7.
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 Standardisé Institute (ETSI), European Committee for Electrotechnical Standardization (CENELEC) and European Broadcasting Union (EBU).
Public broadcasting involves radio, television and other electronic media outlets whose primary mission is public service. Public broadcasters receive funding from diverse sources including license fees, individual contributions, public financing and commercial financing.
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.
Advanced Television Systems Committee (ATSC) standards are an American set of standards for digital television transmission over terrestrial, cable and satellite networks. It is largely a replacement for the analog NTSC standard and, like that standard, is used mostly in the United States, Mexico, Canada, and South Korea. Several former NTSC users, in particular Japan, have not used ATSC during their digital television transition, because they adopted their own system called ISDB.
The Hellenic Broadcasting Corporation or ERT (ΕΡΤ) is the state-owned public radio and television broadcaster of Greece.
Digital terrestrial television is a technology for terrestrial television in which land-based (terrestrial) television stations broadcast television content by radio waves to televisions in consumers' residences in a digital format. DTTV is a major technological advance over the previous analog television, and has largely replaced analog which had been in common use since the middle of the 20th century. Test broadcasts began in 1998 with the changeover to DTTV beginning in 2006 and is now complete in many countries. The advantages of digital terrestrial television are similar to those obtained by digitising platforms such as cable TV, satellite, and telecommunications: more efficient use of limited radio spectrum bandwidth, provision of more television channels than analog, better quality images, and potentially lower operating costs for broadcasters.
Euro1080 was the first commercial broadcaster in Europe to broadcast full-time high-definition television (HDTV) content. It was founded by Gabriel Fehervari in 2004 and is owned by Alfacam, of which declared bankrupt in 2013.
Digital terrestrial television in the United Kingdom encompasses over 100 television, radio and interactive services broadcast via the United Kingdom's terrestrial television network and receivable with a standard television set. The majority of digital terrestrial television (DTT) services, including the five former analogue channels, are broadcast free-to-air, and a further selection of encrypted pay TV services are also available.
1080p is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes informally referred to as 2K, these terms reflect two distinct technical standards, with differences including resolution and aspect ratio.
BBC HD was a high-definition television channel provided by the BBC. The service was initially run as a trial from 15 May 2006 until becoming a full service on 1 December 2007 before closing on 26 March 2013. It broadcast only during the afternoon and evening and only broadcast material shot in high definition, either in a simulcast with another channel or by inserting a repeat of an HD programme.
In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called "multicasting".
9HD is an Australian television channel owned by Nine Entertainment, originally launched on 17 March 2008 featuring unique "breakaway" programming until 2009 and a high-definition simulcast of the Nine Network from 2009 to 2010 and again since 26 November 2015. The channel is available on high definition digital television viewers in metropolitan and regional areas through a number of owned-and-operated and affiliate stations. Originally 9HD only simulcast blocks of programming from the Nine Network, and in 2008 it added time-shifted news, movies, drama and entertainment programs. Following the launch of 9Go! in August 2009, 9HD reverted to a HD simulcast of the Nine Network. The channel was replaced completely in 2010 and the space occupied by the newly launched multichannel 9Gem. Following the government's decision to remove the SD Primary Channel limitations, the channel returned as a HD simulcast on channel 90 on 26 November 2015.
High-definition television describes a television system providing a substantially higher image resolution than the previous generation of technologies. The term has been used since 1936; in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television and Blu-ray Discs.
ABC HD is an Australian free-to-air public television channel.
ERT A is the first multiplexer of ERT and started broadcasting in March 2006 by ERT Digital. The first digital terrestrial television of its kind in Greece started through this multiplexer. Today it covers 80% of the country's population.
