Radio networkThere are two types of radio network currently in use around the world: the one-to-many (simplex communication) broadcast network commonly used for public information and mass-media entertainment, and the two-way radio (duplex communication) type used more commonly for public safety and public services such as police, fire, taxicabs, and delivery services. Cell phones are able to send and receive simultaneously by using two different frequencies at the same time. Many of the same components and much of the same basic technology applies to all three.
Religious broadcastingReligious broadcasting, sometimes referred to as faith-based broadcasts, is the dissemination of television and/or radio content that intentionally has religious ideas, religious experience, or religious practice as its core focus. In some countries, religious broadcasting developed primarily within the context of public service provision (as in the UK), whilst in others, it has been driven more by religious organisations themselves (as in the United States).
Virtual channelIn most telecommunications organizations, a virtual channel is a method of remapping the program number as used in H.222 Program Association Tables and Program Mapping Tables to a channel number that can be entered as digits on a receiver's remote control. Often, virtual channels are implemented in digital television to help users to go to channels easily and in general to ease the transition from analogue to digital broadcasting.
Television studioA television studio, also called a television production studio, is an installation room in which video productions take place, either for the production of live television and its recording onto video tape or other media such as SSDs, or for the acquisition of raw footage for post-production. The design of a studio is similar to, and derived from, movie studios, with a few amendments for the special requirements of television production. A professional television studio generally has several rooms, which are kept separate for noise and practicality reasons.
Viacom (1952–2006)The original incarnation of Viacom Inc. (derived from "Video & Audio Communications") was an American mass media and entertainment conglomerate based in New York City. It began as CBS Television Film Sales, the broadcast syndication division of the CBS television network in 1952; it was renamed CBS Films in 1958, renamed CBS Enterprises in 1968, renamed Viacom in 1970, and spun off into its own company in 1971. Viacom was a distributor of CBS television series throughout the 1970s and 1980s, and also distributed syndicated television programs.
InfomercialAn infomercial is a form of television commercial that resembles regular TV programming yet is intended to promote or sell a product, service or idea. It generally includes a toll-free telephone number or website. Most often used as a form of direct response television (DRTV), they are often program-length commercials (long-form infomercials), and are typically 28:30 or 58:30 minutes in length. Infomercials are also known as paid programming (or teleshopping in Europe).
Police proceduralThe police procedural, police show, or police crime drama, is a subgenre of procedural drama and detective fiction that emphasizes the investigative procedure of police officers, police detectives, or law enforcement agencies as the protagonists, as contrasted with other genres that focus on non-police investigators such as private investigators. As its name implies, the defining element of a police procedural is the attempt to accurately depict law enforcement and their procedures, including such police-related topics as forensic science, autopsies, gathering evidence, search warrants, interrogation and adherence to legal restrictions and procedures.
TelevisaGrupo Televisa S.A.B., simply known as Televisa, is a Mexican multimedia mass media and entertainment company. A major Latin American mass media corporation, it often presents itself as the largest producer of Spanish-language content. In April 2021, Televisa announced that they would sell the company's media and entertainment assets to Univision Communications, which would form a new company to be known as TelevisaUnivision. The transaction was completed on January 31, 2022, with Televisa owning a 45% stake of the company.
Local insertionIn 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.
Radio masts and towersRadio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. The terms "mast" and "tower" are often used interchangeably.
