ERT B

Last updated

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 September 2021, ERT will broadcast from 168 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 open standard for digital television broadcasting

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).

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.

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.

1080p Video mode

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.

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".
