Television Broadcasting
A television broadcaster or television network is a telecommunications network for the distribution of television content, where a central operation provides programming to many television stations, pay television providers or, in the United States, multichannel video programming distributors. Until the mid-1980s, broadcast programming on television in most countries of the world was dominated by a small number of terrestrial networks. Many early television networks such as the BBC, CBC, PBS, PTV, NBC or ABC in the US and in Australia evolved from earlier radio networks. Overview In countries where most networks broadcast identical, centrally originated content to all of their stations, and where most individual television transmitters therefore operate only as large " repeater stations", the terms "television network", " television channel" (a numeric identifier or radio frequency) and "television station" have become mostly interchangeable in everyday language, wit ...

Telecommunications Network
A telecommunications network is a group of Node (networking), nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals. Multiple nodes may cooperate to pass the message from an originating node to the destination node, via multiple network hops. For this routing function, each node in the network is assigned a network address for identification and locating it on the network. The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, and the wireless radio networks of cell phone telecommunication providers.

Breaking News
Breaking news, also called late-breaking news, a special report, special coverage, or a news flash, is a current issue that warrants the interruption of a scheduled broadcast in order to report its details. News broadcasters also use the term for continuing coverage of events of broad interest to viewers, attracting accusations of sensationalism. Formats Breaking news has been common to U.S. mass media since the 1930s, when the mass adoption of radio allowed the public to learn about new events without the need to print an extra edition of a newspaper. Television When a news event warrants an interruption of current non-news programming (or, in some cases, regularly scheduled newscasts), the broadcaster will usually alert all of its affiliates, telling them to stand by for the interruption. The network's feed will then switch to a countdown sequence, to allow any affiliated stations to switch to the network feed. If a national network newscast is in progress when the brea ...

Regional Variation
A regional variation generally refers to times when a radio station or television station simultaneously broadcasts different programs, continuity or advertisements to different parts of its coverage area. This may be so as to provide programming specific to a particular region, such as local news, or may be so as to allow advertisements to be targeted to a particular area. Some regional variations are the consequence of a federal style television network or radio network where a local station is a part of a larger broadcast network and broadcasts the network's programs some of the time and its own programming the rest of the time. The latter is therefore sometimes considered a regional variation. Examples of this include the UK's ITV network throughout much of its history, and American network affiliate stations. Regional variation is also a common term used in British television listings publications, such as magazines and newspapers, to show the different programs broadc ...

Emergency Alert
An emergency is an urgent, unexpected, and usually dangerous situation that poses an immediate risk to health, life, property, or environment and requires immediate action. Most emergencies require urgent intervention to prevent a worsening of the situation, although in some situations, mitigation may not be possible and agencies may only be able to offer palliative care for the aftermath. While some emergencies are self-evident (such as a natural disaster that threatens many lives), many smaller incidents require that an observer (or affected party) decide whether it qualifies as an emergency. The precise definition of an emergency, the agencies involved and the procedures used, vary by jurisdiction, and this is usually set by the government, whose agencies ( emergency services) are responsible for emergency planning and management. Defining an emergency An incident, to be an emergency, conforms to one or more of the following, if it: * Poses an immediate threat to life, ...

Station Identification
Station identification (ident, network ID, channel ID or bumper (broadcasting), bumper) is the practice of radio and television stations and broadcast network, networks identifying themselves on-air, typically by means of a call sign or brand name (sometimes known, particularly in the United States, as a "sounder", "stinger" or "sting (musical phrase), sting", more generally as a station or network ID). This may be to satisfy requirements of licensing authorities, a form of branding, or a combination of both. As such, it is closely related to production logos, used in television and cinema alike. Station identification used to be done regularly by an announcer at the halfway point during the presentation of a television program, or in between programs. Asia In Southeast Asia, idents are known as a ''montage'' in Thailand and the Malay world (except Indonesia, known as ''station ID'', terminology shared with the Philippines), and as an ''interlude'' in Cambodia and Vietnam.

Local Insertion
In broadcasting, local insertion (known in the United Kingdom as an opt-out) is the act or capability of a broadcast television station, radio station or cable system to insert or replace part of a network feed with content unique to the local station or system. Most often this is a station identification (required by the broadcasting authority such as the U.S. Federal Communications Commission), but is also commonly used for television or radio advertisements, or a weather or traffic report. A digital on-screen graphic ("dog" or "bug"), commonly a translucent watermark, may also be keyed (superimposed) with a television station ID over the network feed using a character generator using genlock. In cases where individual broadcast stations carry programs separate from those shown on the main network, this is known as regional variation (in the United Kingdom) or an opt-out (in Canada and the United States). Automated local insertion used to be triggered with in-band signali ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cable Channel
Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over-the-air by radio waves and received by a television antenna, or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation. A cable channel (sometimes known as a cable network) is a television network available via cable television. Many of the same channels are distributed through sa ...
