720p60
720p (1280×720 px; also called HD ready, standard HD or just HD) is a progressive HDTV signal format with 720 horizontal lines/1280 columns and an aspect ratio (AR) of 16:9, normally known as widescreen HDTV (1.78:1). All major HDTV broadcasting standards (such as SMPTE 292M) include a 720p format, which has a resolution of 1280×720; however, there are other formats, including HDV Playback and AVCHD for camcorders, that use 720p images with the standard HDTV resolution. The frame rate is standards-dependent, and for conventional broadcasting appears in 50 progressive frames per second in former PAL/SECAM countries (Europe, Australia, others), and 59.94 frames per second in former NTSC countries (North America, Japan, Brazil, others). The number ''720'' stands for the 720 horizontal scan lines of image display resolution (also known as 720 pixels of vertical resolution). The ''p'' stands for progressive scan, i.e. non-interlaced. When broadcast at 60 frames per second, 720p f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AVCHD
AVCHD (Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video. It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around the camcorders. Developed jointly by Sony and Panasonic, the format was introduced in 2006 primarily for use in high definition consumer camcorders. Related specifications include the professional variants AVCCAM and NXCAM. Favorable comparisons of AVCHD against HDV and XDCAM EX solidified perception of AVCHD as a format acceptable for professional use. Both Panasonic and Sony released the first consumer AVCHD camcorders in spring of 2007. Panasonic released the first AVCHD camcorder aimed at the professional market in 2008, though it was nothing more than the (by then discontinued) FLASH card consumer model rebadged with a different model number. In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-definition Television
High-definition television (HD or HDTV) describes a television system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since 1936; in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television and Blu-ray Discs. Formats HDTV may be transmitted in various formats: * 720p (1280 horizontal pixels × 720 lines): 921,600 pixels * 1080i (1920×1080) interlaced scan: 1,036,800 pixels (~1.04 MP). * 1080p (1920×1080) progressive scan: 2,073,600 pixels (~2.07 MP). ** Some countries also use a non-standard CEA resolution, such as 1440×1080i: 777,600 pixels (~0.78 MP) per field or 1,555,200 pixels (~1.56 MP) per frame When transmitted at two megapixels per frame, HDTV provides about five times ...

Telecine
Telecine ( or ) is the process of transferring film into video and is performed in a color suite. The term is also used to refer to the equipment used in the post-production process. Telecine enables a motion picture, captured originally on film stock, to be viewed with standard video equipment, such as television sets, video cassette recorders (VCR), DVD, Blu-ray Disc or computers. Initially, this allowed television broadcasters to produce programs using film, usually 16mm stock, but transmit them in the same format, and quality, as other forms of television production. Furthermore, telecine allows film producers, television producers and film distributors working in the film industry to release their productions on video and allows producers to use video production equipment to complete their filmmaking projects. Within the film industry, it is also referred to as a TK, because TC is already used to designate timecode. Motion picture film scanners are similar to telecines. ...

Interlaced Video
Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. The interlaced signal contains two fields of a video frame captured consecutively. This enhances motion perception to the viewer, and reduces flicker by taking advantage of the phi phenomenon. This effectively doubles the time resolution (also called ''temporal resolution'') as compared to non-interlaced footage (for frame rates equal to field rates). Interlaced signals require a display that is natively capable of showing the individual fields in a sequential order. CRT displays and ALiS plasma displays are made for displaying interlaced signals. Interlaced scan refers to one of two common methods for "painting" a video image on an electronic display screen (the other being progressive scan) by scanning or displaying each line or row of pixels. This technique uses two fields to create a frame. One field contains all od ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Widescreen
Widescreen images are displayed within a set of aspect ratios (relationship of image width to height) used in film, television and computer screens. In film, a widescreen film is any film image with a width-to-height aspect ratio greater than the standard 1.37:1 Academy aspect ratio provided by 35 mm film. For television, the original screen ratio for broadcasts was in fullscreen 4:3 (1.33:1). Largely between the 1990s and early 2000s, at varying paces in different nations, 16:9 (1.78:1) widescreen TV displays came into increasingly common use. They are typically used in conjunction with high-definition television (HDTV) receivers, or Standard-Definition (SD) DVD players and other digital television sources. With computer displays, aspect ratios wider than 4:3 are also referred to as widescreen. Widescreen computer displays were previously made in a 16:10 aspect ratio (e.g. 1680 × 1050), but now are usually 16:9 (e.g. 1920 × 1080). Film History Widescreen was ...

Ultra-high-definition Television
Ultra-high-definition television (also known as Ultra HD television, Ultra HD, UHDTV, UHD and Super Hi-Vision) today includes 4K UHD and 8K UHD, which are two digital video formats with an aspect ratio of 16:9. These were first proposed by NHK Science & Technology Research Laboratories and later defined and approved by the International Telecommunication Union (ITU). The Consumer Electronics Association announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of 16:9 or wider and at least one digital input capable of carrying and presenting native video at a minimum resolution of . In 2015, the Ultra HD Forum was created to bring together the end-to-end video production ecosystem to ensure interoperability and produce industry guidelines so that adoption of ultra-high-definition television could accelerate. From just 30 in Q3 2015, the forum published a list up to 55 commercial services available aroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4K Resolution
4K resolution refers to a horizontal display resolution of approximately 4,000 pixels. Digital television and digital cinematography commonly use several different 4K resolutions. In television and consumer media, 38402160 (4K Ultra-high-definition television, UHD) is the dominant 4K standard, whereas the digital cinema, movie projection industry uses 40962160 (Digital Cinema Initiatives, DCI 4K). The 4K television market share increased as prices fell dramatically during 2014 and 2015. 4K standards and terminology The term "4K" is generic and refers to any resolution with a horizontal pixel count of approximately 4,000. Several different 4K resolutions have been standardized by various organizations. The terms "4K" and "Ultra HD" are used more widely in marketing than "2160p". While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3840×2160 ...

Vlaamse Radio- En Televisieomroeporganisatie
The VRT (), is the national public-service broadcaster for the Flemish Community of Belgium. History VRT is the successor to a succession of organisations. The Belgian National Institute of Radio Broadcasting was known as the Nationaal Instituut voor de Radio-omroep (NIR) in Flemish and the L'Institut National de Radiodiffusion (INR) in French, was founded in 1930 and existed until 1960. This became the Belgische Radio- en Televisieomroep (BRT) in 1960 and the Belgische Radio- en Televisieomroep Nederlandstalige Uitzendingen (BRTN) from 1991 to 1998. The NIR/INR and BRT (Radio-Télévision Belge, or RTB, in French) had each been single state-owned entities with separate Dutch- and French-language production departments. They were housed in Le Flagey, formerly known as the Maison de la Radio, from when the new building was completed in 1938 until 1974, when the building became too small. However, in 1977, as part of the ongoing state reform in Belgium broadcasting became r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
France Télévisions
France Télévisions (; stylized since 2018 as ) is the French national public television broadcaster. It is a state-owned company formed from the integration of the public television channels France 2 (formerly Antenne 2) and France 3 (formerly France Régions 3), later joined by the legally independent channels France 4 (formerly Festival), France 5 (formerly La Cinquième) and France Info.

ARD (broadcaster)
ARD is a joint organisation of Germany's regional public-service broadcasters. It was founded in 1950 in West Germany to represent the common interests of the new, decentralised, post-war broadcasting services – in particular the introduction of a joint television network. The ARD has a budget of €6.9 billion, 22,612 employees and is the largest public broadcaster network in the world. The budget comes primarily from a licence fee which every household, company and public institution are required by law to pay. For an ordinary household the fee is currently €18.36 per month. Households living on welfare are exempt from the fee. The fees are not collected directly by the ARD, but by the Beitragsservice (formerly known as Gebühreneinzugszentrale GEZ), a common organisation of the ARD member broadcasters, the second public TV broadcaster ZDF, and Deutschlandradio. ARD maintains and operates a national television network, called '' Das Erste'' ("The First") to differentiate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
