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 ...

DOG Jimbo
The dog (''Canis familiaris'' or ''Canis lupus familiaris'') is a domesticated descendant of the gray wolf. Also called the domestic dog, it was selectively bred from a population of wolves during the Late Pleistocene by hunter-gatherers. The dog was the first species to be domesticated by humans, over 14,000 years ago and before the development of agriculture. Due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other canids. Dogs have been bred for desired behaviors, sensory capabilities, and physical attributes. Dog breeds vary widely in shape, size, and color. They have the same number of bones (with the exception of the tail), powerful jaws that house around 42 teeth, and well-developed senses of smell, hearing, and sight. Compared to humans, dogs possess a superior sense of smell and hearing, but inferior visual acuity. Dogs perform many roles for humans, such as hunting, herding, pull ...

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. Some topics in computer graphics include user interface design, Sprite (computer graphics), sprite graphics, raster graphics, Rendering (computer graph ...

Clock Ident
A clock ident is a form of television ident in which a clock is displayed, reading the current time, and usually alongside the logo of that particular television station. Clock idents are typically used before news bulletins and closedown, though in the past quite commonly preceded regular programming. In the United Kingdom, clock idents are also associated with schools programming. Appearance Clock idents are typically displayed as an analogue clock, although some broadcasters have experimented with digital clocks. In particular, during the 1970s and 1980s, many ITV regions in the UK adopted digital clock designs, which are overlaid onto a coloured card using CSO. The backgrounds were generally static, but some clocks had movement. For example, Associated-Rediffusion had a spinning Adastral. The final clocks from 1995 to 1998, used by RTÉ One and RTÉ Two, were overlaid onto a video background. The first station clocks were mechanical, but were converted to an electronic ...

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] |
Digital Watermark
A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data.H.T. Sencar, M. Ramkumar and A.N. Akansu: ''Data Hiding Fundamentals and Applications: Content Security in Digital Multimedia''. Academic Press, San Diego, CA, USA, 2004. It is typically used to identify ownership of the copyright of such a signal. Digital watermarking is the process of hiding digital information in a carrier signal; the hidden information should,Ingemar J. Cox: ''Digital watermarking and steganography''. Morgan Kaufmann, Burlington, MA, USA, 2008 but does not need to, contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Like traditional physical watermarks, digital watermarks are often only perceptible under certain conditions, e.g. af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).

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 ...

Screen Burn-in
Screen burn-in, image burn-in, ghost image, or shadow image, is a permanent discoloration of areas on an electronic visual display such as a cathode-ray tube (CRT) in an older computer monitor or television set. It is caused by cumulative non-uniform use of the screen. Newer liquid-crystal displays (LCDs) may suffer from a phenomenon called image persistence instead, which is not permanent. One way to combat screen burn-in was the use of screensavers, which would move an image around to ensure that no one area of the screen remained illuminated for too long. Causes With phosphor-based electronic visual displays (i.e. CRT-type computer monitors, oscilloscope screens, and plasma displays), non-uniform use of specific areas, such as prolonged display of non-moving images (text or graphics), repetitive contents in gaming graphics, or certain broadcasts with tickers and flags, can create a permanent ghost-like image of these objects or otherwise degrade image quality. This is beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcast Designer
A broadcast designer is a person involved with creating graphic designs and electronic media incorporated in television productions that are used by character generator (CG) Operator (profession), operators. A broadcast designer may have a degree in digital media (or a similar degree), or is self-taught in the software needed to create such content. CG stands for computer graphics, most broadcast designers studied either graphic design or visual communicationthis term is used for those designing motion graphics also for film, industrials, commercials, and the web. Broadcast designers take part in their field in creating visual content that combines creativity and technology. Broadcast design is the creation and combination of visual elements in a television production or Television show, television shows. These elements can include news graphics, channel logos, animation, and more. Broadcast designers not only have to be creative with visuals and aesthetics, but also have to have ...

Genlock
Genlock (generator locking) is a common technique where the video output of one source (or a specific reference signal from a signal generator) is used to synchronize other picture sources together. The aim in video applications is to ensure the coincidence of signals in time at a combining or switching point. When video instruments are synchronized in this way, they are said to be ''generator-locked'', or ''genlocked''. Possible problems Video signals generated and output by generator-locked instruments are said to be syntonized. Syntonized video signals will be precisely frequency-locked, but because of delays caused by the unequal transmission path lengths, the synchronized signals will exhibit differing phases at various points in the television system. Modern video equipment such as production switchers that have multiple video inputs often include a variable delay on each input to compensate for the phase differences and time all the input signals to precise phase coinc ...

Amiga
Amiga is a family of personal computers produced by Commodore International, Commodore from 1985 until the company's bankruptcy in 1994, with production by others afterward. The original model is one of a number of mid-1980s computers with 16-bit or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. These include the Atari ST as well as the Macintosh 128K, Macintosh and Acorn Archimedes. The Amiga differs from its contemporaries through custom hardware to accelerate graphics and sound, including sprite (computer graphics), sprites, a blitter, and four channels of sample-based audio. It runs a pre-emptive multitasking operating system called AmigaOS, with a desktop environment called Workbench (AmigaOS), Workbench. The Amiga 1000, based on the Motorola 68000 microprocessor, was released in July 1985. Production problems kept it from becoming widely available until early 1986. While ...
