Character Generator
A character generator, often abbreviated as CG, is a device or software that produces static or animated text (such as news crawls and credits rolls) for keying into a video stream. Modern character generators are computer-based, and they can generate graphics as well as text. History Monoscopes were used as character generators for text mode video rendering in computer displays for a short time in the 1960s. The CBS Laboratories Vidiac, and the A. B. Dick Videograph 990 System, were among the earliest character generators for broadcast television. CBS Laboratories later developed the more advanced Vidifont system in preparation for the 1968 US presidential elections, where a rapid method of all-electronic character generation was required so that news outlets could identify unexpected interviewees on the spot. A similar generator using analogue electronics, Anchor, was developed by the BBC in 1970 and used in the general election later that year. Usage In the televisio ...

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 where all viewers watch the same stream simultaneously, rather than watching video on demand. 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 scripted television shows remained live until the 1970s, such as soap operas. To prevent unforeseen issues, live television programs may be delayed, which allows censors to edit the program. Some programs may be broadcast live in certain time zones and delayed in others. Types of programs From the early days of television until about 1958, live television was used heavily, except for filmed programs such as ...

Channel Surf
Channel surfing (also known as channel hopping or zapping) is the practice of quickly scanning through different television channels or radio frequencies to find something interesting to watch or listen to. Modern viewers, who may have cable or satellite services beaming down dozens if not hundreds or thousands of channels, are frequently channel surfing. It is common for people to scan channels when commercial broadcasters switch from a show over to running commercials. The term is most commonly associated with television, where the practice became common with the wide availability of the remote control. The first published use of the term is November 1986, in an article by ''The Wall Street Journal''. Viewers' propensity to channel surf was apparently a factor leading toward the current ATSC standard for terrestrial television, digital television in North America. An ATSC signal can be locked onto and start being decoded within about one second, while it can take several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Score Bug
A score bug is a digital on-screen graphic which is displayed at either the top or lower third bottom of the television screen during a broadcast of a sporting event in order to display the current score and other statistics. History The concept of a persistent score bug for association football matches was devised by Sky Sports head David Hill, who was dissatisfied over having to wait to see what the score was after tuning into a match in-progress. The score bug was introduced during Sky's coverage of the then newly-formed English Premier League in August 1992. Hill's boss repeatedly demanded that the graphic be removed, describing it as the "stupidest thing ehad ever seen". Hill defied the boss's demands and kept the graphic in place. ITV introduced a score bug at the start of the 1993–94 football season, and the BBC introduced a score bug towards the end of 1993. The concept was introduced to the United States by ABC Sports and ESPN during coverage of the 1994 FIFA Worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Master Control
Master control is the technical hub of a broadcast operation common among most over-the-air television stations and television networks. It is distinct from a production control room (PCR) in television studios where the activities such as switching from camera to camera are coordinated. A transmission control room (TCR) is usually smaller in size and is a scaled down version of centralcasting. Master control is the final point before a signal is transmitted over-the-air for terrestrial television or cablecast, satellite provider for broadcast, or sent on to a cable television operator. Television master control rooms include banks of video monitors, satellite receivers, videotape machines, video servers, transmission equipment, and, more recently, computer broadcast automation equipment for recording and playback of television programming. Master control is generally staffed with one or two master control operators around-the-clock to ensure continuous operation. Master c ...

Computer Graphics
Computer graphics deals with generating images and art with the aid of computers. Computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications. A great deal of specialized hardware and software has been developed, with the displays of most devices being driven by graphics hardware, computer graphics hardware. It is a vast and recently developed area of computer science. The phrase was coined in 1960 by computer graphics researchers Verne Hudson and William Fetter of Boeing. It is often abbreviated as CG, or typically in the context of film as Computer-generated imagery, computer generated imagery (CGI). The non-artistic aspects of computer graphics are the subject of Computer graphics (computer science), computer science research.

Motion Graphics
Motion graphics (sometimes mograph) are pieces of animation or digital footage that create the illusion of motion or rotation, and are usually combined with audio for use in multimedia projects. Motion graphics are usually displayed via electronic media technology, but may also be displayed via manual powered technology (e.g. thaumatrope, phenakistoscope, stroboscope, zoetrope, praxinoscope, flip book). The term distinguishes static graphics from those with a transforming appearance over time, without over-specifying the form. While any form of experimental or abstract animation can be called motion graphics, the term typically more explicitly refers to the commercial application of animation and effects to video, film, TV, and interactive applications. History of the term Since there is no universally accepted definition of motion graphics, the official beginning of the art form is disputed. There have been presentations that could be classified as motion graphics as early as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compositing
Compositing is the process or technique of combining visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene. Live action, Live-action shooting for compositing is variously called "chroma key", "blue screen", "green screen" and other names. Today, most compositing is achieved through digital image manipulation. Pre-digital compositing techniques, however, go back as far as the trick films of Georges Méliès in the late 19th century, and some are still in use. Basic procedure All compositing involves the replacement of selected parts of an image with other material, usually, but not always, from another image. In the digital method of compositing, software commands designate a narrowly defined color as the part of an image to be replaced. Then the software (e.g. Natron (software), Natron) replaces every pixel within the designated color range with a pixel from another image, aligned to appear ...
