Interruptible Fold Back
Interruptible foldback (IFB), also known as interrupted foldback, interruptible feedback, or interrupt for broadcast, is a monitoring and cue (theatrical), cueing system used in television, filmmaking, video production, and radio broadcast for one-way communication from the TV director, director or assistant director to on-air talent or a remote location. The names are backronyms for the Telex Communications, Telex IFB-XXX model line. Less common names for the system include program cue interrupt (PCI) and switched talkback. IFB is often facilitated using an earpiece that on-air persons wear to get cues, feedback or direction from their control rooms. The earpiece itself may also be referred to as an IFB. Sometimes IFB is accomplished by the director talking to off-camera personnel who visually cue the on-camera talent. The IFB is a special intercom Telecommunication circuit, circuit that consists of a mix-minus program feed sent to an earpiece worn by talent via a wire, telephone ...

Mix-minus
In audio engineering, a mix-minus or clean feed is a particular setup of a mixing console or matrix mixer, such that an output of the mixer contains everything ''except'' a designated input. Mix-minus is often used to prevent echoes or feedback in broadcast or sound reinforcement systems. Examples The most common situation in which a mix-minus is used is when a telephone hybrid is connected to a console, usually at a radio station. The person on the telephone hears all relevant feeds, usually an identical mix to that of the master bus, including the DJ's mic feed, except that the caller does not hear their own voice. Because the feed being returned to the telephone has an identical mix, minus only one input, it is most efficient to employ a mix-minus as opposed to creating and mixing for a new independent output bus. Mix-minus is also often used together with IFB systems in electronic news gathering (ENG) for television news reporters and interview subjects speaking to a ho ...

Cue (theatrical)
A theatrical cue is the trigger for an action to be carried out at a specific time. It is generally associated with theatre and the film industry. They can be necessary for a lighting change or effect, a sound effect, or some sort of stage or set movement/change. Types Cues are generally given by the stage manager as a verbal signal over the headset system or backstage intercom, by a signal with a 'cue light' or by a show control system. There are 3 types of cues given. Warning, Standby, and Go. *Warning: Given about a minute prior to the cue and gives time for crew members to get ready and make sure everything is set (this is especially important with cues for set or rail changes). *Standby: Given a few seconds before the cue and tells the crew members everything should be set and they should be standing by to go. *Go: Given at the moment the cue should be executed. This sets the crew members in action. Calling and execution There are several common methods for the stage manag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
News Anchor
A news presenter – also known as a newsreader, newscaster (short for "news broadcaster"), anchorman or anchorwoman, news anchor or simply an anchor – is a person who presents news during a news program on TV, radio or the Internet. They may also be a working journalist, assisting in the collection of news material and may, in addition, provide commentary during the program. News presenters most often work from a television studio or radio studio, but may also present the news from remote locations in the field related to a particular major news event. History The role of the news presenter developed over time. Classically, the presenter would read the news from news "copy" which they may or may not have helped write with a news writer. This was often taken almost directly from wire services and then rewritten. Prior to the television era, radio-news broadcasts often mixed news with opinion and each presenter strove for a distinctive style. These presenters were r ...

In-ear Monitor
In-ear monitors (IEMs) are devices used by musicians, audio engineers and audiophiles to listen to music or to hear a personal mix of vocals and stage instrumentation for live performance or recording studio mixing. They are also used by television presenters in order to receive vocal instructions, info, and breaking news announcements from a producer that only the presenter hears. They are often custom fitted for an individual's ears to provide comfort and a high level of noise reduction from ambient surroundings. Their origins as a tool in live music performance can be traced back to the mid-1980s. A stage monitor system is any system that provides a mix of audio sources to a performer on stage. Traditionally, loudspeakers were placed on the stage directed toward the performers. These loudspeakers can have disadvantages. First, floor wedges greatly increase the onstage volume, in some cases to potential hearing damage levels. Second, while floor wedges can be placed in front ...

Propagation Delay
Propagation delay is the time duration taken for a signal to reach its destination. It can relate to networking, electronics or physics. ''Hold time'' is the minimum interval required for the logic level to remain on the input after triggering edge of the clock pulse. Networking In computer networks, propagation delay is the amount of time it takes for the head of the signal to travel from the sender to the receiver. It can be computed as the ratio between the link length and the propagation speed over the specific medium. Propagation delay is equal to ''d / s'' where ''d'' is the distance and ''s'' is the wave propagation speed. In wireless communication, ''s''=''c'', i.e. the speed of light. In copper wire, the speed ''s'' generally ranges from .59c to .77c. This delay is the major obstacle in the development of high-speed computers and is called the interconnect bottleneck in IC systems. Electronics In electronics, digital circuits and digital electronics, the propagati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Auxiliary Service
A broadcast auxiliary service or BAS is any radio frequency system used by a radio station or TV station, which is not part of its direct broadcast to listeners or viewers. These are essentially internal-use backhaul channels not intended for actual reception by the public, but part of the airchain required to get those signals back to the broadcast studio from the field. usually to be integrated into a live production. Examples include: * studio/transmitter link (STL) * transmitter/studio link (TSL) *remote pickup unit (RPU) * electronic news gathering (ENG) Several of these bands exist, but the most frequently used band is the 2 GHz microwave BAS band for point-to-point transmission from mobile newsgathering units to mountaintop receivers. Seven 12-MHz wide channels exist in the band. In North America, DVB-T, precisely the same modulation technique as European Broadcast, is used, using a constellation of QPSK, 16QAM, or 64QAM, enabling sufficient digital bandwidths at 6 M ...

Return Link
In communications systems, the return channel (also reverse channel or return link) is the transmission link from a user terminal to the central hub. Return links are often, but not always, slower than the corresponding forward links. Examples where this is true include asymmetric digital subscriber line, cable modems, mobile broadband and satellite internet access. The return channel need not use the same medium as the main channel. For example, some hybrid Internet access services use a one-way cable television system for the forward channel and a dial-up modem for the return channel. Even when the return and forward channels use the same medium, their differences often dictate the use of very different data modulation and coding techniques. For example, in a star radio network, only the central hub transmits on the forward link, so channel access method is a consideration only on the return link. The "forward/return" terminology is also used for spacecraft communication links fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telephone Hybrid
A telephone hybrid is the component at the ends of a subscriber line of the public switched telephone network (PSTN) that converts between two-wire and four-wire forms of bidirectional audio paths. When used in broadcast facilities to enable the airing of telephone callers, the broadcast-quality telephone hybrid is known as a broadcast telephone hybrid or telephone balance unit. The need for hybrids comes from the nature of analog plain old telephone service (POTS) home or small business telephone lines, where the two audio directions are combined on a single two-wire pair. Within the telephone network, switching and transmission are almost always four-wire circuits with the two signals being separated. Hybrids perform the necessary conversion. In older analog networks, conversion to four-wire was required so that repeater amplifiers could be inserted in long-distance links. In today's digital systems, each speech direction must be processed and transported independently. The line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic News Gathering
Electronic news-gathering (ENG) or electronic journalism (EJ) is usage of electronics, electronic video and sound recording and reproduction, audio technologies by journalist, 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. Beginnings Shortcomings of film The term ENG was created as television news departments moved from film-based news-gathering to electronic field production technology in the 1970s. Since film requires chemical processing before it can be viewed and edited, it generally took at least an hour from the time the film arrived back at the television station or network news department until it was ready to be broadcast. Film editing was done by hand on what was known as "Complementary colors, color reversal" film, usually Eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breaking News
Breaking news, interchangeably termed late-breaking news and also known as a special report or special coverage or news flash, is a current issue that broadcasters feel warrants the interruption of scheduled programming or current news in order to report its details. Its use is also assigned to the most significant story of the moment or a story that is being covered live. It could be a story that is simply of wide interest to viewers and has little impact otherwise. Many times, breaking news is used after the news organization has already reported on the story. When a story has not been reported on previously, the graphic and phrase "Just In" is sometimes used instead. Formats Television The format of a ''special report'' or ''breaking news'' event on broadcast television commonly consists of the following: 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 it ...

Live Television
Live television is a television production broadcast in real-time, as events happen, in the present. In a secondary meaning, it may refer to streaming television over the Internet when content or programming is played continuously (not on demand). For example, the Pluto TV app has two categories for viewing: "Live TV" & "On Demand." On its website, Xfinity states "Watch TV series and top rated movies live and on demand with Xfinity Stream." In most cases live programming is not being recorded as it is shown on TV, but rather was not rehearsed or edited and is being shown only as it was recorded prior to being aired. Shows broadcast live include newscasts, morning shows, awards shows, sports programs, reality programs and, occasionally, episodes of scripted television series. Live television was more common until the late 1950s, when videotape technology was invented. Because of the prohibitive cost, adoption was slow, and some television shows remained live until the 1970s, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cue Card
Cue cards, also known as note cards, are cards with words written on them that help actors and speakers remember what they have to say. They are typically used in television productions where they can be held off-camera and are unseen by the audience. Cue cards are still currently being used on many late night talk shows including ''The Tonight Show Starring Jimmy Fallon'', ''Late Night with Seth Meyers'' and '' Conan'' as well as variety and sketch comedy shows like ''Saturday Night Live'' due to the practice of last minute script changes. Many other TV shows, including game and reality shows, still use cue cards due to their mobility, as a teleprompter only allows the actor or broadcaster to look directly into the camera. History Cue cards were originally used to aid aging actors. One early use was by John Barrymore in the late 1930s. Cue cards however did not become widespread until 1949 when Barney McNulty a CBS page and former military pilot, was asked to write ailing ...
