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] |
Digital 3&4
Digital 3&4 is a consortium consisting of ITV plc, STV Group plc and the Channel Four Television Corporation, which operates a multiplex broadcasting from a number of transmitter sites in the United Kingdom, carrying television and radio channels, together with interactive services, from both ITV and Channel 4. Unlike other multiplexes, the regional ITV broadcaster has control over which services are to be broadcast on their allotted amount of the capacity, leading to small regional differences across the country. Channels carried *ITV1 / STV *ITV1 +1 / STV +1 (except Channel Islands) *ITV2 *ITV3 *ITV4 *ITVBe (Channel Islands only, in the GB mainland it's on COM4) *Channel 4 * S4C (Wales only) *Channel 4 +1 *Film4 *More4 * E4 *E4 +1 * Channel 5 *Freeview Information page *Accessible TV Guide See also *List of digital terrestrial television channels (UK) This is a list of the current channels available on digital terrestrial television (DTT) in the United Kingdom, and thos ...

DVB-T2
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. This system transmits compressed digital audio, video, and other data in "physical layer pipes" (PLPs), using OFDM modulation with concatenated channel coding and interleaving. The higher offered bit rate, with respect to its predecessor DVB-T, makes it a system suited for carrying HDTV signals on the terrestrial TV channel (though many broadcasters still use plain DVB-T for this purpose). , it was implemented in broadcasts in the United Kingdom (Freeview HD, eight channels across two multiplexes, plus an extra multiplex in Northern Ireland carrying three SD channels), Italy ( Europa 7 HD, twelve channels), Finland (21 channels, five in HD), Germany (six HD (1080p50) channels, with 40 in planning), ...

Bauer Northern Ireland
Bauer Media Audio UK is a UK-based radio division of the Bauer Media Group. History In early 2008, German magazine publisher Bauer bought the radio division of British company Emap, which had been established as East Midland Allied Press in 1947. Consequently, Emap Radio Limited was renamed to Bauer Radio Limited. Emap's assets included national stations Kiss, Kerrang! and Magic, and local stations under the Big City Network brand in England, Scotland and Northern Ireland. These included 22 local FM stations in Scotland which Emap had bought from Scottish Radio Holdings in 2005. In April 2011, Bauer Radio announced it would be restructuring its radio portfolio into two divisions: locally focused and heritage stations – including many of the Big City stations, South Coast station Wave 105 and London station Magic 105.4 FM – would become part of the "Bauer Place" division, with branded music-category stations such as Kiss and Kerrang forming a second sub-brand, "Bauer Pa ...

Digital Switchover
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. The transition may also involve analogue cable conversion to digital cable or Internet Protocol television, as well as analog to digital satellite television. Transition of land based broadcasting was begun by some countries around 2000. By contrast, transition of satellite television systems was well underway or completed in many countries by this time. It is an i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiplexing
In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium. The aim is to share a scarce resource - a physical transmission medium. For example, in telecommunications, several telephone calls may be carried using one wire. Multiplexing originated in telegraphy in the 1870s, and is now widely applied in communications. In telephony, George Owen Squier is credited with the development of telephone carrier multiplexing in 1910. The multiplexed signal is transmitted over a communication channel such as a cable. The multiplexing divides the capacity of the communication channel into several logical channels, one for each message signal or data stream to be transferred. A reverse process, known as demultiplexing, extracts the original channels on the receiver end. A device that performs the multiplexing is called a multiplexer (MUX), and a dev ...

Coverage Map
Coverage maps are designed to indicate the service areas of radiocommunication transmitting stations. Typically these may be produced for radio or television stations, for mobile telephone networks and for satellite networks. Such maps are alternatively known as propagation maps. For satellite networks, a coverage map is often known as a footprint. Definition of coverage Typically a coverage map will indicate the area within which the user can expect to obtain good reception of the service in question using standard equipment under normal operating conditions. Additionally, the map may also separately denote supplementary service areas where good reception may be obtained but other stations may be stronger, or where the reception may be variable but the service may still be usable. Technical details The field strength that the marked service boundary on a coverage map represents will be defined by whoever produces the map, but typical examples are as follows: VHF(FM) / Band II ...
