IntercomAn intercom, also called an intercommunication device, intercommunicator, or interphone, is a stand-alone voice communications system for use within a building, small collection of buildings or portably within a small coverage area, which functions independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles, but can also be detachable and portable. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones, and other intercom systems.
Outside broadcastingOutside broadcasting (OB) is the electronic field production (EFP) of television or radio programmes (typically to cover television news and sports television events) from a mobile remote broadcast television studio. Professional video camera and microphone signals come into the production truck for processing, recording and possibly transmission. Some outside broadcasts use a mobile production control room (PCR) inside a production truck. Outside radio broadcasts have been taking place since the early 1920s and television ones since the late 1920s.
Television crewTelevision crew positions are derived from those of film crew, but with several differences. Pre-production Work before shooting begins is called the pre-production stage. The crew in this stage include the casting director, costume designer, director, location manager, make-up artist, researcher, screenwriter, set designer, and television producer. Casting director The casting director casts actors, and so is usually one of the first crew members on the project.
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.
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.
News broadcastingNews broadcasting is the medium of broadcasting various news events and other information via television, radio, or the internet in the field of broadcast journalism. The content is usually either produced locally in a radio studio or television studio newsroom, or by a broadcast network. It may include material such as sports coverage, weather forecasts, traffic reports, political commentary, expert opinions, editorial content, and other material that the broadcaster feels is relevant to their audience.
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.
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.
Microwave transmissionMicrowave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300MHz to 300GHz(1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles.
