Phone-in
In broadcasting, a phone-in or call-in is a programme format in which viewers or listeners are invited to air their live comments by telephone, usually in respect of a specific topic selected for discussion on the day of the broadcast. On radio (especially talk radio), it is common for an entire programme to be dedicated to a phone-in session. On television, phone-in's are often part of a wider discussion programme: a current example in the UK is the "Jeremy Vine" TV show. The concept dates to the early radio era: a December 1924 BBC 5NG Nottingham phone-in programme is described in a 1925 Radio Times article: "listeners ... enjoyed the novelty of hearing their own voices taking part". A prior attempted phone-in to a BBC 2LO London programme "led to such a rush on the telephones that the Post Office had to intervene". Speech based Talk Radio UK was launched in 1995, with much of its programming featuring phone-ins. It also introduced the notion of the shock jock to the UK, with ...

ITV Play
ITV Play was a short-lived 24/7 participation television channel in the United Kingdom owned by ITV plc. The ITV Play name continued as a strand on the main ITV Network until December 2007. It was launched as a standalone channel on Freeview (taking on the slot which was previously occupied by the Men & Motors channel) on 19 April 2006 and started broadcasting on the Sky platform on 24 July 2006. The ITV Play channel was created in response to and hoping to cash in on the popularity of late night quiz shows on the ITV Network and ITV2 such as ''Quizmania'' and ''The Mint''. ITV Play also offered additional gambling services on their website. It cost at least 75p per call to participate. This charge was made even if the caller was not put through to the studio. A free entry route was available through the website. Users were restricted to 150 calls/web entries in a 24-hour period. At peak times callers had a 1 in 8500 chance of getting through to the studio to play. Criticism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liveline
''Liveline'' is an Irish radio interview and phone-in chat show broadcast on RTÉ Radio 1 each weekday afternoon between 13.45 and 15.00. The programme, which is currently presented by Joe Duffy and known for its slogan "Talk to Joe", seeks the public's opinion on various questions, normally one or more controversial current events. According to ''The New York Times'', it is Ireland's "most popular radio call-in program". According to the ''Irish Independent'', "His greeting at 1.45pm every weekday -- "Hello, good afternoon and you're very welcome to Liveline"—is the signal for 400,000 listeners to sit back and await some lively debate or the exposure of a scam or a social scandal". From its launch in 1985, ''Liveline'' was originally presented and produced by Marian Finucane and Doireann Ní Bhriain, but has been presented by Joe Duffy since 1999. During the presenter's absence, the role of presenter is typically filled by Philip Boucher-Hayes, Damien O'Reilly or previously ...

Joe Duffy
Joseph Duffy (born 27 January 1956) is an Irish broadcaster employed by Raidió Teilifís Éireann (RTÉ). One of RTÉ's highest-earning stars, he is the current presenter of ''Liveline'', an interview and phone-in chat show broadcast on RTÉ Radio 1 on Mondays to Fridays between 13:45 and 15:00. Duffy has a history as a student activist. As President of the Union of Students in Ireland (U.S.I.) he was once jailed for an occupation in which he had participated. He describes himself as a Christian socialist who advocates justice "very much based on Christian teaching and principles". Duffy retraced his Christian roots in 2010 by hosting an RTÉ One TV show called ''Joe Duffy's Spirit Level'' which discussed the great faith of the Irish people and various religions present in the country, and also queried whether David McSavage's satirical portrayal of Duffy could be considered blasphemous. Duffy is married, is the father of triplets, and resides in Clontarf, Dublin. He won a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Hybrid
A telephone hybrid is the component at the ends of a subscriber line of the public switched telephone network (PSTN) that converts between two-wire and four-wire forms of bidirectional audio paths. When used in broadcast facilities to enable the airing of telephone callers, the broadcast-quality telephone hybrid is known as a broadcast telephone hybrid or telephone balance unit. The need for hybrids comes from the nature of analog plain old telephone service (POTS) home or small business telephone lines, where the two audio directions are combined on a single two-wire pair. Within the telephone network, switching and transmission are almost always four-wire circuits with the two signals being separated. Hybrids perform the necessary conversion. In older analog networks, conversion to four-wire was required so that repeater amplifiers could be inserted in long-distance links. In today's digital systems, each speech direction must be processed and transported independently. The line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Line
A telephone line or telephone circuit (or just line or circuit industrywide) is a single-user circuit on a telephone communication system. It is designed to reproduce speech of a quality that is understandable. It is the physical wire or other signaling medium connecting the user's telephone apparatus to the telecommunications network, and usually also implies a single telephone number for billing purposes reserved for that user. Telephone lines are used to deliver landline telephone service and Digital subscriber line (DSL) phone cable service to the premises. Telephone overhead lines are connected to the public switched telephone network. The voltage at a subscriber's network interface is typically 48 V between the ring and tip wires, with tip near ground and ring at -48 V. In the United States In 1878, the Bell Telephone Company began to use two-wire circuits, called the local loop, from each user's telephone to end offices which performed any necessary electrical s ...

Mixing Console
A mixing console or mixing desk is an electronic device for mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds. Mixers may control analog or digital signals. The modified signals are summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded. Mixing consoles are used for applications including recording studios, public address systems, sound reinforcement systems, nightclubs, broadcasting, and post-production. A typical, simple application combines signals from microphones on stage into an amplifier that drives one set of loudspeakers for the audience. A DJ mixer may have only two channels, for mixing two record players. A coffeehouse's tiny stage might only have a six-channel mixer, enough for two singer-guitarists and a percussionist. A nigh ...

Impedance Matching
In electronics, impedance matching is the practice of designing or adjusting the input impedance or output impedance of an electrical device for a desired value. Often, the desired value is selected to maximize power transfer or minimize signal reflection. For example, impedance matching typically is used to improve power transfer from a radio transmitter via the interconnecting transmission line to the antenna. Signals on a transmission line will be transmitted without reflections if the transmission line is terminated with a matching impedance. Techniques of impedance matching include transformers, adjustable networks of lumped resistance, capacitance and inductance, or properly proportioned transmission lines. Practical impedance-matching devices will generally provide best results over a specified frequency band. The concept of impedance matching is widespread in electrical engineering, but is relevant in other applications in which a form of energy, not necessarily el ...

Sound Quality
Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to the sound or gauge its ''perceived'' similarity to another sound. The sound quality of a reproduction or recording depends on a number of factors, including the equipment used to make it, processing and mastering done to the recording, the equipment used to reproduce it, as well as the listening environment used to reproduce it. In some cases, processing such as equalization, dynamic range compression or stereo processing may be applied to a recording to create audio that is significantly different from the original but may be perceived as more agreeable to a listener. In other cases, the goal may be to reproduce audio as closely as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Signal Processing
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency. In digital electronics, a digital signal is represented as a pulse train, which is typically generated by the switching of a transistor. Digital signal processing and analog signal processing are subfields of signal processing. DSP applications include audio and speech processing, sonar, radar and other sensor array processing, spectral density estimation, statistical signal processing, digital image processing, data compression, video coding, audio coding, image compression, signal processing for telecommunications, control systems, biomedical engineering, and seismology, among others. DSP can involve linear or nonli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Call
A telephone call is a connection over a telephone network A telephone network is a telecommunications network that connects telephones, which allows telephone calls between two or more parties, as well as newer features such as fax and internet. The idea was revolutionized in the 1920s, as more and more ... between the called party and the calling party. First telephone call The first telephone call was made on March 10, 1876, by Alexander Graham Bell. Bell demonstrated his ability to "talk with electricity" by transmitting a call to his assistant, Thomas Watson. The first words transmitted were "Mr Watson, come here. I want to see you." This event has been called Bell's "greatest success", as it demonstrated the first successful use of the telephone. Although it was his greatest success, he refused to have a telephone in his own home because it was something he invented by mistake and saw it as a distraction from his main studies.
