E4 is a British digital television channel, launched as a pay-TV companion to Channel 4 on 18 January 2001. The "E" stands for entertainment, and the channel is mainly aimed at the lucrative 15–35 age group. Programming includes US imports such as The Goldbergs, The Cleveland Show, The O.C., Smallville, Veronica Mars, Everwood, What About Brian?, Desperate Housewives, How I Met Your Mother, 90210, One Tree Hill, Ugly Betty, Scrubs, Rules of Engagement, The Big Bang Theory, 2 Broke Girls, Revenge, and formerly Friends. Other programming includes British shows such as Skins, My Mad Fat Diary, Misfits, The Inbetweeners, The Ricky Gervais Show, Shameless, Hollyoaks, and Made in Chelsea. Some US imports, such as Desperate Housewives and Ugly Betty are screened on E4 up to one week ahead of their Channel 4 broadcasts. Its most successful broadcast to date was on 11 October 2010 when an episode of The Inbetweeners pulled in over 3.7 million viewers.
On 16 December 2004, Channel 4 announced that the subscription channel would return to digital terrestrial television. From its launch until the closure of ITV Digital it was available as a bonus subscription channel. It became part of the Top Up TV subscription scheme until 27 May 2005, when the channel became available on Freeview, with the potential to increase advertising revenue by attracting a larger audience.
TV channel 16/12 — is the only independent news TV channel in Kazakhstan.
The Kazakhstan’s authorities have repeatedly tried to stop the broadcasting of Channel 16/12. The Channel’s employees were intimidated, arrested, their offices were searched and the equipment needed for their work seized. Specifically, in 2014, officers of the National Security Committee of Kazakhstan, along with law enforcement officers of Russia, burst into the office of the production company which was making videos for the TV Channel 16/12. They conducted a search, withdrew hard discs from the operating computers and took them away. Soon after that, a similar search was conducted in the Astana office of a company which was also making videos for the opposition channel. During the search, the equipment needed for their work was seized. Prior to this, Sanat Urnaliyev, journalist of TV Channel 16/12, and Viktor Gudz, the cameraman, were subjected to administrative arrest on a fake charge, along with a correspondent of Radio Azattyk, the Kazakh service of the Radio Liberty.
In computing, a channel is a model for interprocess communication and synchronization via message passing. A message may be sent over a channel, and another process or thread is able to receive messages sent over a channel it has a reference to, as a stream. Different implementations of channels may be buffered or not, and either synchronous or asynchronous.
Channels are fundamental to the process calculus approach to concurrency, and originated in communicating sequential processes (CSP), a formal model for concurrency, and has been used in many derived languages, such as occam, and Limbo programming language (via Newsqueak and the Alef programming language). They are also used in the C programming language threading library libthread, and in Plan 9 from Bell Labs, which uses libthread, as well as in Stackless Python and the Go programming language.
Channels modeled after the CSP model are inherently synchronous: a process waiting to receive an object from a channel will block until the object is sent. This is also called rendezvous behaviour. Typical supported operations are presented below using the example of the libthread channel API.
A price channel is a pair of parallel trend lines that form a chart pattern for a stock or commodity. Channels may be horizontal, ascending or descending. When prices pass through and stay through a trendline representing support or resistance, the trend is said to be broken and there is a "breakout".
Color digital images are made of pixels, and pixels are made of combinations of primary colors represented by a series of code. A channel in this context is the grayscale image of the same size as a color image, made of just one of these primary colors. For instance, an image from a standard digital camera will have a red, green and blue channel. A grayscale image has just one channel.
In the digital realm, there can be any number of conventional primary colors making up an image; a channel in this case is extended to be the grayscale image based on any such conventional primary color. By extension, a channel is any grayscale image the same size with the "proper" image, and associated with it.
"Channel" is a conventional term used to refer to a certain component of an image. In reality, any image format can use any algorithm internally to store images. For instance, GIF images actually refer to the color in each pixel by an index number, which refers to a table where three color components are stored. However, regardless of how a specific format stores the images, discrete color channels can always be determined, as long as a final color image can be rendered.
