Quantel
Quantel was a company based in the United Kingdom and founded in 1973 that designed and manufactured digital production equipment for the broadcast television, video production and motion picture industries. They were headquartered in Newbury, Berkshire. Quantel acquired Snell Ltd. in March 2014. Following a period of consolidation the two companies started operating under the Snell name, trading as Snell Advanced Media or SAM, from September 2015, following the staged removal of the Quantel board of directors by incoming CEO Ray Cross. The name Quantel came from Quantised Television, in reference to the process of converting a television picture into a digital signal. History Quantel founder, Peter Michael, had previously founded Micro Consultants Group (MCG). MCG had pioneered a range of fast data conversion products that could be used for converting video signals from analog to digital and back to analog. These devices found use in many early Quantel products. In the 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantel Paintbox
The Quantel Paintbox was a dedicated computer graphics workstation for composition of broadcast television video and graphics. Produced by the British production equipment manufacturer Quantel (which, via a series of mergers, is now part of Grass Valley), its design emphasized the studio workflow efficiency required for live news production. At a price of about per unit, they were used primarily by large TV networks such as NBC, while in the UK, Peter Claridge's company CAL Videographics was the first commercial company to purchase one. Following its initial launch in 1981, the Paintbox revolutionised the production of television graphics. Original line Paintbox DPB 7000/7001 The first generation Paintbox, the 1981 ''DPB-7001,'' was built from readily-available off-the-shelf components, supported by Programmable Array Logic ICs which were custom-programmed by Quantel. Artist Martin Holbrook worked with Quantel's development team to develop the artist-oriented functionalit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Link Electronics Ltd
Link Electronics Ltd. was a major UK industrial and broadcast television equipment manufacturer and systems integrator in the 1970s and 1980s. The company was founded by John Tanner and David Mann, who began manufacturing television cameras in 1966. Link was known mainly for its range of broadcast television cameras, but was also a manufacturer of outside broadcast (OB) vehicles, including the BBC "Type 5". Link also produced a wide range of ancillary studio equipment, such as distribution amplifiers, measuring sets and test-signal generators. Cameras Link started as an industrial camera manufacturer but soon moved into broadcast equipment when the BBC approached it to develop a successor to the commercially successful EMI 2001, when EMI's own design for the 2001's successor, the 2005, failed to meet expected standards when launched around 1975. The poor performance of this camera, considering its development cost, led to EMI exiting the broadcast camera industry. A similar ...

Framebuffer
A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame. Modern video cards contain framebuffer circuitry in their cores. This circuitry converts an in-memory bitmap into a video signal that can be displayed on a computer monitor. In computing, a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display. The screen buffer may also be called the video buffer, the regeneration buffer, or regen buffer for short. Screen buffers should be distinguished from video memory. To this end, the term off-screen buffer is also used. The information in the buffer typically consists of color values for every pixel to be shown on the display. Color values are commonly stored in 1-bit binary (monochrome), 4-bit palettized, 8 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carlton Communications
Carlton was a British media company. It was led by Michael P. Green and listed on the London Stock Exchange from 1983 until 2 February 2004, when it was bought by Granada plc in a corporate takeover to form ITV plc. Carlton shareholders gained approximately 32% of ITV plc.

Non-linear Editing
Non-linear editing is a form of offline editing for audio, video, and image editing. In offline editing, the original content is not modified in the course of editing. In non-linear editing, edits are specified and modified by specialized software. A pointer-based playlist, effectively an edit decision list (EDL), for video and audio, or a directed acyclic graph for still images, is used to keep track of edits. Each time the edited audio, video, or image is rendered, played back, or accessed, it is reconstructed from the original source and the specified editing steps. Although this process is more computationally intensive than directly modifying the original content, changing the edits themselves can be almost instantaneous, and it prevents further generation loss as the audio, video, or image is edited. A non-linear editing system (NLE) is a video editing (NLVE) program or application, or an audio editing (NLAE) digital audio workstation (DAW) system. These perform non-des ...

Berkshire
Berkshire ( ; in the 17th century sometimes spelt phonetically as Barkeshire; abbreviated Berks.) is a historic county in South East England. One of the home counties, Berkshire was recognised by Queen Elizabeth II as the Royal County of Berkshire in 1957 because of the presence of Windsor Castle, and letters patent were issued in 1974. Berkshire is a county of historic origin, a ceremonial county and a non-metropolitan county without a county council. The county town is Reading. The River Thames formed the historic northern boundary, from Buscot in the west to Old Windsor in the east. The historic county, therefore, includes territory that is now administered by the Vale of White Horse and parts of South Oxfordshire in Oxfordshire, but excludes Caversham, Slough and five less populous settlements in the east of the Royal Borough of Windsor and Maidenhead. All the changes mentioned, apart from the change to Caversham, took place in 1974. The towns of Abingdon, Didcot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Picture-in-picture
Picture-in-picture (PiP) is a feature that can be found in television receivers, personal computers and smartphones, consisting of a video stream playing within an inset window, freeing the rest of the screen for other tasks. For televisions, picture-in-picture requires two independent tuners or signal sources to supply the large and the small picture. Two-tuner PiP TVs have a second tuner built in, but a single-tuner PiP TV requires an external signal source, which may be an external tuner, videocassette recorder, DVD player, or a cable box. Picture-in-picture is often used to watch one program while waiting for another to start, or advertisements to finish. History Adding a picture into an existing picture was done long before affordable PiP was available on consumer products. The first PiP was seen on the televised coverage of the 1976 Summer Olympics where a Quantel digital framestore device was used to insert a close-up picture of the Olympic flame during the opening ceremo ...

D1 (Sony)
D-1 or 4:2:2 Component Digital is an SMPTE digital recording video standard, introduced in 1986 through efforts by SMPTE engineering committees. It started as a Sony and Bosch - BTS product and was the first major professional digital video format. SMPTE standardized the format within ITU-R 601 (orig. CCIR-601), also known as Rec. 601, which was derived from SMPTE 125M and EBU 3246-E standards. Format D-1 or 4:2:2 D-1 (1986) was a major feat in real time, broadcast quality digital video recording. It stores uncompressed digitized component video, encoded at Y'CbCr 4:2:2 using the CCIR 601 raster format with 8 bits, along with PCM audio tracks as well as timecode on a 3/4 inch (19 mm) videocassette tape (though not to be confused with the ubiquitous 3/4-inch U-Matic/U-Matic SP cassette). The uncompressed component video used enormous bandwidth for its time: 173 Mbit/sec (bit rate). The maximum record time on a D-1 tape is 94 minutes. Because of the uncompromis ...
