Wrexham-Rhos Relay
The Wrexham-Rhos transmitting station is a digital television relay of Moel-y-Parc, and forms part of the Wales television region. Despite its name, the station is situated in Moss Village and serves the city of Wrexham, the northern area of Wrexham County Borough and south-western Flintshire. It is a free-standing lattice tower structure serving around 85,000 homes which are unable to receive broadcasts from Moel-y-Parc due to Hope Mountain. This area is traditionally served by English transmitters at Winter Hill and The Wrekin, which have historically provided English-language channels Channel 4 and Channel 5, plus the digital terrestrial services ONdigital/ITV Digital (from 1998 to 2002) and Freeview from 2002 onwards. Wrexham-Rhos was constructed to coincide with the 1977 National Eisteddfod in Wrexham, initially providing S4C and BBC One Wales, later joined by HTV Wales in 1997 and BBC Two Wales in 1999. The DAB digital radio transmitter on the site was switched on i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ITV Digital
ITV Digital was a British digital terrestrial television broadcaster which launched a pay-TV service on the world's first digital terrestrial television network. Its main shareholders were Carlton Communications plc and Granada plc, owners of two franchises of the ITV network. Starting as ONdigital in 1998, the service was re-branded as ITV Digital in July 2001. Low audience figures, piracy issues and an ultimately unaffordable multi-million pound deal with the Football League led to the broadcaster suffering large losses, and it entered administration in March 2002. Pay television services ceased permanently on 1 May of that year, but carriage of the remaining free-to-air channels such as BBC One and Channel 4 continued. In October, ITV Digital’s former terrestrial multiplexes were taken over by Crown Castle and the BBC to create the Freeview free-to-air service.

MPEG2
MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth. While MPEG-2 is not as efficient as newer standards such as H.264/AVC and H.265/HEVC, backwards compatibility with existing hardware and software means it is still widely used, for example in over-the-air digital television broadcasting and in the DVD-Video standard. Main characteristics MPEG-2 is widely used as the format of digital television signals that are broadcast by terrestrial (over-the-air), cable, and direct broadcast satellite TV systems. It also specifies the format of movies and other programs that are distributed on DVD and similar discs. TV stations, TV receivers, DVD players, and other equipment are often ...

DVB-T
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 (COFDM or OFDM) modulation. It is also the format widely used worldwide (including North America) 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. Basics Rather than carrying one data carrier on a single radio frequency (RF) channel, COFDM works by splitting the digital data stream into a large number of slower digital streams, each of which digitally modulates a set of closely spaced adjacent sub-carrier frequencies. In the cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HTV Wales
ITV Wales and West, previously known as Harlech Television (HTV), was an ITV franchise area in the United Kingdom until 31 December 2013, licensed to a broadcaster by the regulator Ofcom. There is no channel, past or present, named "ITV Wales and West". The licence relates to a "dual region", meaning that the franchise area was divided into two sub-regions, Wales and the West of England, each of which had to be served by distinct and separate ITV programme services, as more fully defined within the licence. From January 2014, the dual-region licence was split in two, with ITV Cymru Wales for Wales and ITV West Country covering the both the West of England sub-region and South West England. Both licences remain held by ITV plc through its subsidiary ITV Broadcasting Ltd, and the legal names of the former HTV companies have not yet been changed again.
