Video

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

Video systems vary greatly in the resolution of the display, how they are refreshed, and the rate of refreshed, and 3D video systems exist. They can also be carried on a variety of media, including radio broadcast, tapes, DVDs, computer files etc.

History

Video technology was first developed for Mechanical television systems, which were quickly replaced by cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.

Video recorders were sold for $50,000 in 1956, and videotapes cost $300 per one-hour reel. However, prices gradually dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) decks and tapes to the public.

National park

A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its Category II type of protected areas.

While this type of national park had been proposed previously, the United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. The first area to use "national park" in its creation legislation was the US's Mackinac Island, in 1875. Australia's Royal National Park, established in 1879, was the world's third official national park. In 1895 ownership of Mackinac Island was transferred to the State of Michigan as a state park and national park status was consequently lost. As a result, Australia's Royal National Park is by some considerations the second oldest national park now in existence.

Kruger National Park

Kruger National Park is one of the largest game reserves in Africa. It covers an area of 19,485 square kilometres (7,523 sq mi) in the provinces of Limpopo and Mpumalanga in northeastern South Africa, and extends 360 kilometres (220 mi) from north to south and 65 kilometres (40 mi) from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926.

To the west and south of the Kruger National Park are the two South African provinces of Limpopo and Mpumalanga. In the north is Zimbabwe, and to the east is Mozambique. It is now part of the Great Limpopo Transfrontier Park, a peace park that links Kruger National Park with the Gonarezhou National Park in Zimbabwe, and with the Limpopo National Park in Mozambique.

The park is part of the Kruger to Canyons Biosphere an area designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as an International Man and Biosphere Reserve (the "Biosphere").

Hotline Bling

"Hotline Bling" is a song by Canadian rapper Drake. It was released as a single on July 31, 2015, the same day that several diss tracks aimed at fellow rapper Meek Mill surfaced on the Internet.

The song received praise and criticism from music reviewers, praising the song for its presentation of Drake's emotional side on the track as well as its production, while others were critical of its lyrical content, considering it sexist. A Director X–directed music video for the song was also released, receiving positive reviews from critics. It subsequently gained popularity on YouTube and spawned several parodies of it. It has been included on numerous year-end critics' polls. "Hotline Bling" received commercial success worldwide, reaching number two on the Billboard Hot 100, becoming Drake's highest-charting single in the United States (tying with "Best I Ever Had" in 2009). It also reached number three in Drake's native Canada and the United Kingdom, where it became his highest-charting single as a lead artist. A spanish version by reggaeton and R&B singer Randy was released on February 2016.

Video game

A video game is an electronic game that involves human interaction with a user interface to generate visual feedback on a video device such as a TV screen or computer monitor. The word video in video game traditionally referred to a raster display device, but it now implies any type of display device that can produce two- or three-dimensional images. Video games are sometimes believed to be a form of art, but this designation is controversial.

The electronic systems used to play video games are known as platforms; examples of these are personal computers and video game consoles. These platforms range from large mainframe computers to small handheld computing devices. Specialized video games such as arcade games, while common in the 1980s, have gradually declined in use due to the widespread availability of home video game devices (e.g., PlayStation 4 and Xbox One) and video games on desktop and laptop computers and smartphones.

The input device used for games, the game controller, varies across platforms. Common controllers include gamepads, mouses, keyboards, joysticks, the touchscreens of mobile devices and buttons. In addition to video and (in most cases) audio feedback, some games include haptic, vibration or force feedback peripherals.
