Standardization
Standardization (American English) or standardisation (British English) is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. Standardization can help maximize compatibility, interoperability, safety, repeatability, efficiency, and quality. It can also facilitate a normalization of formerly custom processes. In social sciences, including economics, the idea of ''standardization'' is close to the solution for a coordination problem, a situation in which all parties can realize mutual gains, but only by making mutually consistent decisions. Divergent national standards impose costs on consumers and can be a form of non-tariff trade barrier.

SMPTE
The Society of Motion Picture and Television Engineers (SMPTE) (, rarely ), founded by Charles Francis Jenkins in 1916 as the Society of Motion Picture Engineers or SMPE, is a global professional association of engineers, technologists, and executives working in the media and entertainment industry. As an internationally recognized standards organization, SMPTE has published more than 800 technical standards and related documents for broadcast, filmmaking, digital cinema, audio recording, information technology (IT), and medical imaging. SMPTE also publishes the ''SMPTE Motion Imaging Journal'', provides networking opportunities for its members, produces academic conferences and exhibitions, and performs other industry-related functions. SMPTE membership is open to any individual or organization with an interest in the subject matter. In the US, SMPTE is a 501(c)(3) organization, 501(c)3 non-profit charitable organization.

SMPTE 259M
SMPTE 259M is a standard published by SMPTE which "describes a 10-bit serial digital interface operating at 143/270/360 Mb/s." The goal of SMPTE 259M is to define a serial digital interface (based on a coaxial cable), called SDI or SD-SDI. There are 4 bit rate In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time. The bit rate is expressed in the unit bit per second (symbol: bit/s), often in conjunction ...s defined, which are normally used to transfer the following standard video formats: References Film and video technology SMPTE standards {{Measurement-stub ...

Serial Digital Interface
Serial digital interface (SDI) is a family of digital video Interface (computing), interfaces first standardized by SMPTE (The Society of Motion Picture and Television Engineers) in 1989. For example, ITU-R BT.656 and SMPTE 259M define digital video interfaces used for Broadcasting, broadcast-grade video. A related standard, known as high-definition serial digital interface (HD-SDI), is standardized in SMPTE 292M; this provides a nominal data rate of 1.485 Gbit/s. Additional SDI standards have been introduced to support increasing video resolutions (High definition video, HD, Ultra high definition, UHD and beyond), High frame rate, frame rates, 3D video, stereoscopic (3D) video, and color depth. Dual link HD-SDI consists of a pair of SMPTE 292M links, standardized by SMPTE 372M in 1998; this provides a nominal 2.970 Gbit/s interface used in applications (such as digital cinema or HDTV 1080P) that require greater fidelity and resolution than standard HDTV can provide. 3 ...

EDTV
''EDtv'' is a 1999 American satirical comedy film directed by Ron Howard. An adaptation of the Quebecois film '' Louis 19, King of the Airwaves (Louis 19, le roi des ondes)'' (1994), it stars Matthew McConaughey, Jenna Elfman, Woody Harrelson, Ellen DeGeneres, Martin Landau, Rob Reiner, Sally Kirkland, Elizabeth Hurley, Clint Howard, and Dennis Hopper. The movie received mixed-to-positive reviews, with some criticizing its similarity to '' The Truman Show'' (1998), and was a box office failure, grossing $35.2 million against an $80 million production budget. Plot Television network True TV is commencing interviews for a planned reality show that shows a normal person's life 24/7, created by TV producer Cynthia. They interview Ed Pekurny and his brother, Ray. When the producers see the interview, Cynthia chooses Ed. The show hits the airwaves under the title "Ed TV." It is a total failure at first, as only boring things happen. The producers want to pull the plug, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
480p
480p is the shorthand name for a family of video display resolutions. The p stands for progressive scan, i.e. non-interlaced. The ''480'' denotes a vertical resolution of 480 pixels, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio ( 640) or a horizontal resolution of 854 (848 should be used for mod16 compatibility) pixels for an approximate 16:9 aspect ratio ( 853.). Since a pixel count must be a whole number, in Wide VGA displays it is generally rounded up to 854 to ensure inclusion of the entire image. The frames are displayed progressively as opposed to interlaced. 480p was used for many early plasma televisions. Standard definition has always been a 4:3 aspect ratio with a pixel resolution of at 60 Hz for NTSC regions, and 720 or for PAL regions (1024 wide for widescreen displays). However, standard definition defines a 15.7k Hz horizontal scanrate, which means that interlacing has to be used for those resolution modes. The lowercase ...

576p
576p is the shorthand name for a video display resolution. The ''p'' stands for progressive scan, i.e. non-interlaced, the ''576'' for a vertical resolution of 576 pixels (the frame rate can be given explicitly after the letter). Usually it corresponds to a digital video mode with a 4:3 anamorphic resolution of 720x576 and a frame rate of 25 frames per second (576p25), and thus using the same bandwidth and carrying the same amount of pixel data as 576i, but other resolutions and frame rates are possible. ITU-R Recommendation BT.1358 allows the following resolutions, coded as R'G'B' or YCBCR, with timings compatible with BT.656: * 1024 x 576p ( 16:9 square pixel format) * 960 x 576p * 936 x 576p (based on 960 x 576p, blanking the first and last 12 pixels of each line) * 768 x 576p ( 4:3 square pixel format) * 720 x 576p (4:3 anamorphic) * 704 x 576p (based on 720 x 576p, blanking the first and last 8 pixels of each line) * 544 x 576p * 480 x 576p 576p is considered standar ...

Film And Video Technology
A film, also known as a movie or motion picture, is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, emotions, or atmosphere through the use of moving images that are generally, since the 1930s, synchronized with sound and (less commonly) other sensory stimulations. Etymology and alternative terms The name "film" originally referred to the thin layer of photochemical emulsion on the celluloid strip that used to be the actual medium for recording and displaying motion pictures. Many other terms exist for an individual motion-picture, including "picture", "picture show", "moving picture", "photoplay", and "flick". The most common term in the United States is "movie", while in Europe, "film" is preferred. Archaic terms include "animated pictures" and "animated photography". "Flick" is, in general a slang term, first recorded in 1926. It originates in the verb flicker, owing to the flickering appearance of early films. ...
