NHK BS8K
NHK BS8K is a satellite television broadcasting service offered by NHK. Launched on 1 December 2018, it is the world's first television channel to broadcast in 8K resolution. Background NHK Science & Technology Research Laboratories had started to develop an 8K broadcast resolution in 1995. The format was first publicly displayed at the Expo 2005 in Aichi Prefecture, Japan, whereas the first 8K live feed broadcast were tested at the 2012 Summer Olympics in London. Due to the successful tests, plans for a television channel dedicated to airing an 8K resolution were approved by the NHK. On 1 August 2016, NHK started to test an Ultra HD channel on BS17, to prevent terrestrial digital broadcasting on its other networks. It featured a variety of 4K and 8K resolution programming, before concluding on 23 July 2018, after which an 8K network was assigned to a newly created BS 14 channel. Overview NHK BS8K was launched on 1 December 2018 at 10:00 ( JST) as the world's first televis ...

4320p
8K resolution refers to an image or display resolution with a width of approximately 8,000 pixels. 8K UHD () is the highest resolution defined in the Rec. 2020 (UHDTV) standard. 8K display resolution is the successor to 4K resolution. TV manufacturers pushed to make 4K a new standard by 2017. At CES 2019, the first 8K TVs were unveiled. The feasibility of a fast transition to this new standard is questionable in view of the absence of broadcasting resources. It is predicted (2018 forecast by Strategy Analytics) that 8K-ready devices will still only account for 3% of UHD TVs by 2023 with global sales of 11 million units a year. However, TV manufacturers remain optimistic as the 4K market grew much faster than expected, with actual sales exceeding projections nearly six-fold in 2016. In 2013, a transmission network's capability to carry HDTV resolution was limited by internet speeds and relied on satellite broadcast to transmit the high data rates. The demand is expected to drive ...

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 ...

Kōhaku Uta Gassen
, more commonly known simply as ''Kōhaku'', is an annual New Year's Eve television special produced by Japanese public broadcaster NHK. It is broadcast live simultaneously on television and radio, nationally and internationally by the NHK network and by some overseas (mainly cable) broadcasters who buy the program. The show ends shortly before midnight. Before the show began broadcasting on television in late 1953, the show was held on 3 January and only consisted of a radio broadcast. The program divides the most popular music artists of the year into competing teams of red and white. The "red" team or is composed of all female artists (or groups with female vocals), while the "white" team or is all male (or groups with male vocals). At the end of the show, judges and the audience vote to decide which group performed better. The honor of performing on ''Kōhaku'' is strictly by invitation, so only the most successful singing acts in the Japanese entertainment industry can pe ...

International Space Station
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station to ...

A Space Odyssey (film)
''2001: A Space Odyssey'' is a 1968 science fiction novel written by Arthur C. Clarke and the 1968 film directed by Stanley Kubrick. It is a part of Clarke's ''Space Odyssey'' series, the first of four novels and two films. Both the novel and the film are partially based on Clarke's 1948 short story " The Sentinel", an entry in a BBC short story competition, and "Encounter in the Dawn", published in 1953 in the magazine ''Amazing Stories''. Resources After deciding on Clarke's 1948 short story "The Sentinel" as the starting point, and with the themes of man's relationship with the universe in mind, Clarke sold Kubrick five more of his stories to use as background materials for the film. These included "Breaking Strain", "Out of the Cradle, Endlessly Orbiting...", "Who's There?", "Into the Comet", and "Before Eden". Additionally, important elements from two more Clarke stories, "Encounter in the Dawn" and (to a somewhat lesser extent) "Rescue Party", made their way into ...

The Pantheon
The Pantheon (, ; la, Pantheum,Although the spelling ''Pantheon'' is standard in English, only ''Pantheum'' is found in classical Latin; see, for example, Pliny, '' Natural History'36.38 "Agrippas Pantheum decoravit Diogenes Atheniensis". See also '' Oxford Latin Dictionary'', s.v. "Pantheum"; ''Oxford English Dictionary'', s.v"Pantheon" "post-classical Latin ''pantheon'' a temple consecrated to all the gods (6th cent.; compare classical Latin ''pantheum'')". from Greek ''Pantheion'', " empleof all the gods") is a former Roman temple and, since 609 AD, a Catholic church (Basilica di Santa Maria ad Martyres or Basilica of St. Mary and the Martyrs) in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC – 14 AD). It was rebuilt by the emperor Hadrian and probably dedicated  126 AD. Its date of construction is uncertain, because Hadrian chose not to inscribe the new temple but rather to retain th ...

Roman Forum
The Roman Forum, also known by its Latin name Forum Romanum ( it, Foro Romano), is a rectangular forum (plaza) surrounded by the ruins of several important ancient government buildings at the center of the city of Rome. Citizens of the ancient city referred to this space, originally a marketplace, as the ', or simply the '. For centuries the Forum was the center of day-to-day life in Rome: the site of triumphal processions and elections; the venue for public speeches, criminal trials, and gladiatorial matches; and the nucleus of commercial affairs. Here statues and monuments commemorated the city's great men. The teeming heart of ancient Rome, it has been called the most celebrated meeting place in the world, and in all history. Located in the small valley between the Palatine and Capitoline Hills, the Forum today is a sprawling ruin of architectural fragments and intermittent archaeological excavations attracting 4.5 million or more sightseers yearly.

High Efficiency Video Coding
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard designed as part of the MPEG-H project as a successor to the widely used Advanced Video Coding (AVC, H.264, or MPEG-4 Part 10). In comparison to AVC, HEVC offers from 25% to 50% better data compression at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD, and unlike the primarily 8-bit AVC, HEVC's higher fidelity Main 10 profile has been incorporated into nearly all supporting hardware. While AVC uses the integer discrete cosine transform (DCT) with 4×4 and 8×8 block sizes, HEVC uses integer DCT and DST transforms with varied block sizes between 4×4 and 32×32. The High Efficiency Image Format (HEIF) is based on HEVC. , HEVC is used by 43% of video developers, and is the second most widely used video coding format after AVC. Concept In most ways, HEVC is an extensi ...

HDTV
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 a ...
