On-screen Display
An on-screen display (OSD) is an image superimposed on a screen picture, commonly used by modern television sets, VCRs, and DVD players to display information such as volume, channel, and time. History In the past, most adjustments on TV sets were performed with analog controls such as potentiometers and switches. This was used more recently also in monochrome portable TVs. After remote controls were invented, digital adjustments became common. They needed an external display, which was LED, LCD, or VFD based. Including this display increased manufacturing costs. When electronics became more advanced, it became clear that adding some extra devices for an OSD was cheaper than adding a second display device. TV screens had become much bigger and could display much more information than a small second display. OSDs display graphical information superimposed over the picture, which is done by synchronizing the reading from OSD video memory with the TV signal. Some of the first ...

Television Set
A television set or television receiver (more commonly called TV, TV set, television, telly, or tele) is an electronic device for viewing and hearing television broadcasts, or as a computer monitor. It combines a tuner, display, and loudspeakers. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode-ray tube (CRT) technology. The addition of color to broadcast television after 1953 further increased the popularity of television sets in the 1960s, and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for the first recorded media for consumer use in the 1970s, such as Betamax, VHS; these were later succeeded by DVD. It has been used as a display device since the first generation of home computers (e.g. Timex Sinclair 1000) and dedicated video game consoles (e.g., Atari) in the 1980s. By the early 2010s, flat-pane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Television News Screen Layout
A television news screen layout or television news screen interface refers to the layout image displayed during a television news program broadcast. The layouts used differ between television stations and countries, and information displayed may include things such as main news topics and headlines within the lower third, Digital on-screen graphic, channel logos, a news ticker, a time clock, and in some cases weather and information in the economic and financial fields. Different layouts may be used within news broadcasting to achieve varying effects, and designs are often formulated by broadcast designers with the intention of being informative and visually appealing. The main purpose of television news screen layouts is to present to viewers a concentrated level of information within the shortest amount of time possible, whilst maintaining a reasonably adequate balance so that excessive detail does not confuse the viewer.Rodrigues, R., (2012).

HUD (video Gaming)
In video gaming, the HUD (heads-up display) or status bar is the method by which information is visually relayed to the player as part of a game's user interface. It takes its name from the head-up displays used in modern aircraft. The HUD is frequently used to simultaneously display several pieces of information including the player character's health points, items, and an indication of game progression (such as score or level). A HUD may also include elements to aid a player's navigation in the virtual space, such as a mini-map. Common elements While the information that is displayed on the HUD depends greatly on the game, there are many features that players recognize across many games. Most of them are static onscreen so that they stay visible during gameplay. Common features include: * Health/lives – this might include the player's character and possibly other important characters, such as allies or bosses. Real-time strategy games usually show the health of every uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HUD (computing)
A head-up display, or heads-up display, also known as a HUD () or head-up guidance system (HGS), is any transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments. Although they were initially developed for military aviation, HUDs are now used in commercial aircraft, automobiles, and other (mostly professional) applications. Head-up displays were a precursor technology to augmented reality (AR), incorporating a subset of the features needed for the full AR experience, but lacking the necessary registration and tracking between the virtual content and the user's real-world environment.

Digital On-screen Graphic
A digital on-screen graphic, digitally originated graphic (DOG, bug, network bug, or screenbug) is a watermark-like station logo that most television broadcasters overlay over a portion of the screen area of their programs to identify the channel. They are thus a form of permanent visual station identification, increasing brand recognition and asserting ownership of the video signal. The graphic identifies the source of programming, even if it has been time shifting, time-shifted—that is, recorded to videotape, DVD, or a digital personal video recorder such as TiVo. Many of these technologies allow viewers to skip or omit traditional between-programming station identification; thus the use of a DOG enables the station or network to enforce brand identification even when standard commercials are skipped. DOG watermarking helps to reduce off-the-air copyright infringement—for example, the distribution of a current series' episodes on DVD: the watermarked content is easily diffe ...

Computer Monitor
A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a electronic visual display, visual display, support electronics, power supply, Housing (engineering), housing, electrical connectors, and external user controls. The display in modern monitors is typically an Liquid-crystal display, LCD with LED-backlit LCD, LED backlight, having by the 2010s replaced cold-cathode fluorescent lamp, CCFL Backlight, backlit LCDs. Before the mid-2000s, most monitors used a cathode-ray tube, cathode-ray tube (CRT) as the image output technology. A monitor is typically connected to its host computer via DisplayPort, HDMI, USB-C, Digital Visual Interface, DVI, or VGA connector, VGA. Monitors sometimes use other proprietary connectors and signals to connect to a computer, which is less common. Originally computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers ( ...

Graphical User Interface
A graphical user interface, or GUI, is a form of user interface that allows user (computing), users to human–computer interaction, interact with electronic devices through Graphics, graphical icon (computing), icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based user interface, text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard. The actions in a GUI are usually performed through direct manipulation interface, direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and Distributed control system, industrial controls. The term ''GUI'' tends not to be applied to other lower-displa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monochrome
A monochrome or monochromatic image, object or palette is composed of one color (or values of one color). Images using only shades of grey are called grayscale (typically digital) or black-and-white (typically analog). In physics, monochromatic light refers to electromagnetic radiation that contains a narrow band of wavelengths, which is a distinct concept. Application Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-red. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype ("blueprint") images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image. In computing, monochrome has two meanings: * it may mean having only one color which is either on or off (a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camcorder
A camcorder is a self-contained portable electronic device with video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens. The earliest camcorders were tape-based, recording analog signals onto videotape cassettes. In the 2000s, digital recording became the norm, and additionally tape was replaced by storage media such as mini- HDD, MiniDVD, internal flash memory and SD cards. More recent devices capable of recording video are camera phones and digital cameras primarily intended for still pictures, whereas dedicated camcorders are often equipped with more functions and interfaces than more common cameras, such as an internal optical zoom lens that is able to operate silently with no throttled speed, whereas cameras with protract ...
