Electronic field productionElectronic field production (EFP) is a television industry term referring to a video production which takes place in the field, outside of a formal television studio, in a practical location, special venue or fitting environment. Zettl defines EFP as using "both ENG (electronic news gathering) and studio techniques. From ENG it borrows its mobility and flexibility; from the studio it borrows its production care and quality control. EFP takes place on location (which may include shooting in someone's living room) and has to adapt to the location conditions.
Production truckA television production truck or OB van is a small mobile production control room to allow filming of events and video production at locations outside a regular television studio. They are used for remote broadcasts, outside broadcasting (OB), and electronic field production (EFP). Some require a crew of as many as 30 people, with additional trucks for additional equipment as well as a satellite truck, which transmits video back to the studio by sending it up through a communications satellite using a satellite dish, which then transmits it back down to the studio.
Electronic news gatheringElectronic news gathering (ENG) or electronic journalism (EJ) is usage of electronic video and audio technologies by reporters to gather and present news instead of using film cameras. The term was coined during the rise of videotape technology in the 1970s. ENG can involve anything from a single reporter with a single professional video camera, to an entire television crew taking a truck on location. The term ENG was created as television news departments moved from film-based news gathering to electronic field production technology in the 1970s.
RadiodiffusionLa radiodiffusion est l'émission de signaux par l'intermédiaire d'ondes électromagnétiques destinées à être reçues directement par le public en général et s'applique à la fois à la réception individuelle et à la réception communautaire. Ce service peut comprendre des émissions sonores, des émissions de télévision ou d'autres genres d'émission. Il s'agit d'une forme de radiocommunication. Le terme radio est souvent utilisé pour toute la chaîne de conception et de réalisation d'émissions de radio, la transmission avec les émetteurs radio et la réception au travers des postes de radio.
Broadcast engineeringBroadcast engineering is the field of electrical engineering, and now to some extent computer engineering and information technology, which deals with radio and television broadcasting. Audio engineering and RF engineering are also essential parts of broadcast engineering, being their own subsets of electrical engineering. Broadcast engineering involves both the studio and transmitter aspects (the entire airchain), as well as remote broadcasts. Every station has a broadcast engineer, though one may now serve an entire station group in a city.
InterphoneUn interphone (en anglais, intercom) est un téléphone qui utilise un réseau interne ; il n'est donc pas connecté au réseau téléphonique. Il est souvent équipé d'un haut-parleur et permet des communications sur de courtes distances, en général à l'intérieur d'un même bâtiment. Un interphone peut notamment être placé à l'entrée d'un immeuble afin d'en contrôler l'accès, est alors parfois doublé d'un visiophone. Dans ce cas, on parle également de parlophone (surtout en Belgique).

Un faisceau hertzien est un système de transmission de signaux mono-directionnel ou bi-directionnel et généralement permanent, entre deux sites géographiques fixes. Il exploite le support d'ondes radioélectriques, par des fréquences porteuses allant de (gamme des micro-ondes), focalisées et concentrées grâce à des antennes directives.
Camera pedestalA camera pedestal is an item upon which television cameras are mounted, typically seen in television studios. Unlike tripods, pedestals give camera operators the ability to move the camera in any direction (left, right, forward, back, up, down). They are commonly used on shiny-floor shows, sitcoms and soap operas. Whilst pedestals are most commonly seen in self-contained television studios, they are also seen on outside broadcasts. A pedestal typically consists of three main parts: a base (with wheels), the column (with steering ring), and the platform.
Professional video cameraA professional video camera (often called a television camera even though its use has spread beyond television) is a high-end device for creating electronic moving images (as opposed to a movie camera, that earlier recorded the images on film). Originally developed for use in television studios or with outside broadcast trucks, they are now also used for music videos, direct-to-video movies (see digital movie camera), corporate and educational videos, wedding videos, among other uses.
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.
