Webdiffusion
vignette|Homme qui diffuse quelque chose sur le web. La webdiffusion (ou webcasting, mot anglais dont la traduction littérale est « diffusion sur le web ») désigne la diffusion de contenus audio et/ou vidéo sur Internet. La diffusion peut s'effectuer en flux continu ou en téléchargement. Selon le site de l'Office québécois de la langue française : . En France, la Commission générale de terminologie et de néologie a adopté les termes « diffusion systématique sur la toile » et « diffusion sur la toile » mais ces derniers ne semblent pas être passés dans l'usage courant.
Television studio
A 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.
Promo (media)
A promo (a shorthand term for promotion) is a form of commercial advertising used in broadcast media, either television or radio, which promotes a program airing on a television or radio station/network to the viewing or listening audience. Promos usually appear during commercial breaks, although sometimes they appear during another program. Promos typically run from 15 to 60 seconds, with 30-second spots being the most common, although some occasionally last run as little as five seconds or as long as 90 seconds.
Electronic news gathering
Electronic 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.
Audience (média)
L'audience d'un média définit l'ensemble des individus exposés, ou leur nombre ; elle fait l'objet de mesures : l'audimétrie (souvent en France, on parle d'audimat, bien que ce soit en réalité une marque de Médiamétrie, qui est donc utilisée comme nom). L'audimétrie relève de sondages. Il est parfois improprement fait référence à des audiences, au pluriel. Cet emploi concerne en fait, les résultats (de mesure) d'audience. Il existe cinq indicateurs : La part d'audience (PDA) ou part de marché (PDM) est l'indicateur le plus utilisé.
Cable converter box
A cable converter box or television converter box is an electronic tuning device that transposes/converts channels from a cable television service to an analog RF signal on a single channel, usually VHF channel 3 or 4, or to a different output for digital televisions such as HDMI. The device allows a television set that is not "cable ready" to receive cable channels. While later televisions were "cable ready" with a standard converter built-in, the existence of premium television (aka pay per view) and the advent of digital cable have continued the need for various forms of these devices for cable television reception.
Electronic media
Electronic media are media that use electronics or electromechanical means for the audience to access the content. This is in contrast to static media (mainly print media), which today are most often created digitally, but do not require electronics to be accessed by the end user in the printed form. The primary electronic media sources familiar to the general public are video recordings, audio recordings, multimedia presentations, slide presentations, CD-ROM and online content. Most new media are in the form of digital media.
Multichannel Multipoint Distribution Service
Le MMDS Multichannel Multipoint Distribution System, soit en français « Système de Distribution Multipoint Multicanal » (SDMM), est un système de diffusion de la télévision par voir hertzienne normalisé au début des années 1990. Par ce procédé, les programmes télévisuels sont diffusés par un émetteur terrestre qui fonctionne dans des bandes de fréquences micro-ondes de 2,6 ou 3,5 GHz (bande S et C) selon les pays. Les signaux sont analogiques, en modulation de fréquence ou en modulation d'amplitude.
Communication simplex
En télécommunications, la communication simplex utilise un canal de communication qui envoie l’information dans une direction seulement. Un canal de communication « duplex » nécessite deux canaux « simplex » qui envoient l’information dans des directions opposées. Selon l’union internationale des télécommunications (UIT), le terme simplex désigne un canal de communication qui fonctionne dans une direction à la fois, mais dont la direction peut être inversée ; ce mode de communication est aussi appelé half-duplex dans d’autres contextes.
