Effio
Sony EFFIO HD CCTV Video Format is an uncompressed analog streaming video format used in for closed-circuit television especially used for crime prevention and video surveillance and monitoring. As of August 2012, little is known about the inner workings of the format. It does seem to be a version of the broadcast uncompressed streaming SDI, similar to HDCCTV, HDMI High-Definition Multimedia Interface (HDMI) is a proprietary digital interface used to transmit high-quality video and audio signals between devices. It is commonly used to connect devices such as televisions, computer monitors, projectors, gam ..., and DVI. Effio chips can be assembled in a variety of CCTV Cameras and are common in usage by many manufacturers of CCTV Cameras. Thursday, 19 January 2017 References Video formats {{Tv-tech-stub ...

Closed-circuit Television
Closed-circuit television (CCTV), also known as video surveillance, is the use of closed-circuit television cameras to transmit a signal to a specific place on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point, point-to-multipoint (P2MP), or mesh wired or wireless links. Even though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that require additional security or ongoing monitoring ( videotelephony is seldom called "CCTV"). The deployment of this technology has facilitated significant growth in state surveillance, a substantial rise in the methods of advanced social monitoring and control, and a host of crime prevention measures throughout the world. Though surveillance of the public using CCTV is common in many areas around the world, video surveillance has generated significant debate about balancing its us ...

Analog Signal
An analog signal (American English) or analogue signal (British and Commonwealth English) is any continuous-time signal representing some other quantity, i.e., ''analogous'' to another quantity. For example, in an analog audio signal, the instantaneous signal voltage varies continuously with the pressure of the sound waves. In contrast, a digital signal represents the original time-varying quantity as a sampled sequence of quantized values. Digital sampling imposes some bandwidth and dynamic range constraints on the representation and adds quantization noise. The term ''analog signal'' usually refers to electrical signals; however, mechanical, pneumatic, hydraulic, and other systems may also convey or be considered analog signals. Representation An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, ...

Streaming Media
Streaming media refers to multimedia delivered through a Computer network, network for playback using a Media player (other), media player. Media is transferred in a ''stream'' of Network packet, packets from a Server (computing), server to a client-server model, client and is rendered in real-time; this contrasts with file downloading, a process in which the end-user obtains an entire media file before consuming the content. Streaming is more commonly used for video on demand, streaming television, and music streaming services over the Internet. While streaming is most commonly associated with multimedia from a remote server over the Internet, it also includes offline multimedia between devices on a local area network. For example, using DLNA and a home server, or in a personal area network between two devices using Bluetooth (which uses radio waves rather than Internet Protocol, IP). Online streaming was initially popularized by RealNetworks and Microsoft in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video
Video is an Electronics, electronic medium for the recording, copying, playback, broadcasting, and display of moving picture, moving image, visual Media (communication), media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types. Video systems vary in display resolution, Display aspect ratio, aspect ratio, refresh rate, color capabilities, and other qualities. Analog and digital variants exist and can be carried on a variety of media, including radio broadcasts, magnetic tape, optical discs, Video file format, computer files, and Streaming media, network streaming. Etymology The word ''video'' comes from the Latin verb ''video,'' meaning to see or ''videre''. And as a noun, "that which is displayed on a (television) screen," History Analog video Video developed from facsimile systems developed in the mid-19th century. Early mecha ...

Crime Prevention
Crime prevention refers to strategies and measures that seek to reduce the risk of crime occurring by intervening before a crime has been committed. It encompasses many approaches, including developmental, situational, community-based and criminal-justice interventions, to address risk factors at individual, family, community and societal levels. These strategies aim to deter potential offenders, reduce opportunities for offending and mitigate the fear of crime among the public, and are used by many governments in their efforts to reduce crime, enforce the law, maintain criminal justice and uphold overall stability. Studies Criminologists, commissions and research bodies such as the World Health Organization, the United Nations, the United States National Research Council and the UK Audit Commission have analyzed their and others' research on what lowers the rates of interpersonal crime. They agree that governments must go beyond law enforcement and criminal justice to tackle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

HDMI
High-Definition Multimedia Interface (HDMI) is a proprietary digital interface used to transmit high-quality video and audio signals between devices. It is commonly used to connect devices such as televisions, computer monitors, projectors, gaming consoles, and personal computers. HDMI supports uncompressed video and either compressed or uncompressed digital audio, allowing a single cable to carry both signals. Introduced in 2003, HDMI largely replaced older analog video standards such as composite video, S-Video, and VGA connector, VGA in consumer electronics. It was developed based on the CEA-861 standard, which was also used with the earlier Digital Visual Interface (DVI). HDMI is electrically compatible with DVI video signals, and adapters allow interoperability between the two without signal conversion or loss of quality. Adapters and active converters are also available for connecting HDMI to other video interfaces, including the older analog formats, as well as digital fo ...

Digital Video Interactive
Digital Video Interactive (DVI) was the first multimedia desktop video standard for IBM-compatible personal computers. It enabled full-screen, full motion video, as well as stereo audio, still images, and graphics to be presented on a DOS-based desktop computer using a special compression chipset. The scope of Digital Video Interactive encompasses a file format, including a digital container format, a number of video and audio compression formats, as well as hardware associated with the file format. History Development of DVI was started around 1984 by Section 17 of The David Sarnoff Research Center Labs (DSRC) then responsible for the research and development activities of RCA. When General Electric purchased RCA in 1986, GE considered the DSRC redundant with its own labs, and sought a buyer. In 1988, GE sold the DSRC to SRI International, but sold the DVI technology separately to Intel corporation. DVI technology allowed full-screen, full motion digital video, as well as stere ...
