Kitzbüheler Horn Transmitter
The Kitzbüheler Horn Transmitter (german: Sender Kitzbüheler Horn) is a transmission tower made of reinforced concrete on the summit of the Kitzbüheler Horn near Kitzbühel in Austria. The Kitzbühler Horn Transmitter does not have a cylindrical shaft. It broadcasts TV and VHF radio programmes. The tower was taken into service on 12 December 1969 as a combined radio and television transmission facility for the ORF after a difficult two-year-long construction period, preceded by lengthy and intensive negotiations with local authorities and land owners. To facilitate the switchover to DVB-T, the analogue channels ORF 1 ORF 1 (''ORF eins'') is an Austrian public television channel owned by ORF. It was the first television channel in Austria, started in 1955. ORF 1 is one of four public TV channels in Austria. It is funded by a mixture of advertising revenue and ...

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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Tyrol (state)
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATV (Austria)
ATV is the largest commercial television station in Austria, and was the first commercial station to be aired via transmitters after a long time when commercial broadcasts in Austria were only possible via satellite or cable and the national public broadcaster ORF held a monopoly of using the airwaves. According to the current broadcasting legislation in Austria, ATV has to be transmitted nationwide alongside the two public channels ORF1 and ORF2 via digital terrestrial television and satellite as well as all cable companies in Austria have to provide at least these three channels to their subscribers. Satellite broadcasts are encrypted as are the ORF channels but it is possible to watch ATV by using the decoding cards issued by ORF. These cards can be obtained only by people living in Austria and paying the television license fees. Another important Austrian commercial television stations available on digital terrestrial television, satellite and cable is Puls 4, although the ...

Bit Rate
In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time. The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction with an SI prefix such as kilo (1 kbit/s = 1,000 bit/s), mega (1 Mbit/s = 1,000 kbit/s), giga (1 Gbit/s = 1,000 Mbit/s) or tera (1 Tbit/s = 1,000 Gbit/s). The non-standard abbreviation bps is often used to replace the standard symbol bit/s, so that, for example, 1 Mbps is used to mean one million bits per second. In most computing and digital communication environments, one byte per second (symbol: B/s) corresponds to 8 bit/s. Prefixes When quantifying large or small bit rates, SI prefixes (also known as metric prefixes or decimal prefixes) are used, thus: Binary prefixes are sometimes used for bit rates. The International Standard ( IEC 80000-13) specifies differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coded Orthogonal Frequency-division Multiplexing
In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a type of digital transmission and a method of encoding digital data on multiple carrier frequencies. OFDM has developed into a popular scheme for wideband digital communication, used in applications such as digital television and audio broadcasting, DSL internet access, wireless networks, power line networks, and 4G/ 5G mobile communications. OFDM is a frequency-division multiplexing (FDM) scheme that was introduced by Robert W. Chang of Bell Labs in 1966. In OFDM, multiple closely spaced orthogonal subcarrier signals with overlapping spectra are transmitted to carry data in parallel.webe.org - 2GHz BAS Relocation Tech-Fair, COFDM Technology Basics 2007-03-02 Demo ...

Forward Error Correction
In computing, telecommunication, information theory, and coding theory, an error correction code, sometimes error correcting code, (ECC) is used for controlling errors in data over unreliable or noisy communication channels. The central idea is the sender encodes the message with redundant information in the form of an ECC. The redundancy allows the receiver to detect a limited number of errors that may occur anywhere in the message, and often to correct these errors without retransmission. The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. ECC contrasts with error detection in that errors that are encountered can be corrected, not simply detected. The advantage is that a system using ECC does not require a reverse channel to request retransmission of data when an error occurs. The downside is that there is a fixed overhead that is added to the message, thereby requiring a hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modulation
In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the '' carrier signal'', with a separate signal called the ''modulation signal'' that typically contains information to be transmitted. For example, the modulation signal might be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal representing a sequence of binary digits, a bitstream from a computer. The carrier is higher in frequency than the modulation signal. In radio communication the modulated carrier is transmitted through space as a radio wave to a radio receiver. Another purpose is to transmit multiple channels of information through a single communication medium, using frequency-division multiplexing (FDM). For example in cable television which uses FDM, many carrier signals, each modulated with a different television channel, are transported throug ...

Multiplex (TV)
A multiplex or mux (called virtual sub-channel in the United States and Canada, and bouquet in France) is a grouping of program services as interleaved data packets for broadcast over a network or modulated multiplexed medium. The program services are split out at the receiving end. In the United Kingdom, a terrestrial ''multiplex'' (usually abbreviated ''mux'') has a fixed bandwidth of 8 MHz CODFM of interleaved H.222 packets containing a number of ''channels''. In the United States, a similar arrangement using 6 MHz 8VSB is often described as a ''channel'' with ''virtual sub-channels''. Pay television multiplexes In regards to television, the term multiplex is often used to refer to a single broadcaster offering multiple channels of programming as a single bundle to its subscribers. The term is most synonymous with premium television services, such as those devoted to films (where the term evokes the symbolism of multiplex cinemas) or sports; for instance, film services may ...

TV Channel
A television channel is a terrestrial frequency or virtual number over which a television station or television network is distributed. For example, in North America, "channel 2" refers to the terrestrial or cable band of 54 to 60 MHz, with carrier frequencies of 55.25 MHz for NTSC analog video ( VSB) and 59.75 MHz for analog audio ( FM), or 55.31 MHz for digital ATSC ( 8VSB). Channels may be shared by many different television stations or cable-distributed channels depending on the location and service provider Depending on the multinational bandplan for a given regional n, analog television channels are typically 6, 7, or 8 MHz in bandwidth, and therefore television channel frequencies vary as well. Channel numbering is also different. Digital terrestrial television channels are the same as their analog predecessors for legacy reasons, however through multiplexing, each physical radio frequency (RF) channel can carry several digital subchannels. ...

Life Radio
The Pentecostal Missionary Church of Christ (4th Watch), also known as PMCC (4th Watch), is a nontrinitarian Christian denomination based in the Philippines. It was founded in 1971 by Arsenio T. Ferriol and registered on August 27, 1973. The church claims to be the 'One True Church of Christ', with its beliefs coming from the Bible as the sole basis for all its doctrines and prophecies about the 'Church of Jesus Christ' established by a living modern-day Apostle in the modern era (whereas the church doctrine calls it "The 4th Watch") (Filipino transl. "Ikaapat na Pagpupuyat") The church has an estimated 800,000 members worldwide and 900 local churches across the globe, with Marikina Main Church serving as the largest and headquarters of the denomination.

Radio Tirol
Radio Tirol is the regional radio for Tyrol and the German-speaking population of South Tyrol, and is part of the Österreich 2 group. It is broadcast by the ORF, and the programmes from Radio Tirol are made in the ORF Tirol Studio. History The first radio broadcasting tryouts in Tyrol started in 1926 in Aldrans close to Innsbruck. The history of the ORF Tirol Studio reaches back to the 1945 built "''Sendergruppe West''. This group had 2 studios, one in Tyrol and one in Vorarlberg. In 1952 the transmitters were handed over to the state government of Tyrol. The program was mixed, from news and information shows to classical music, radio dramas and other features. In the literature department of Radio Tirol, talents like Axel Corti, Otto Grünmandl or Bert Breit were found. During 1954 and 1956 the ''Sendergruppe West'' was integrated into the |
