HIFI (TV channel)

HIFI is a Canadian English language Category B specialty channel. The channel is owned by Blue Ant Media and broadcasts completely in high definition. HIFI broadcasts musical and art-based programming in the form of films, concerts, documentaries, and more.

History

In August 2005, John S. Panikkar (co-founder of High Fidelity HDTV), was granted a licence by the Canadian Radio-television and Telecommunications Commission (CRTC) to launch Artefact HD, a digital HD specialty channel devoted to "collectors and their collections, and will showcase creations, celebrate beauty, intricacy, aesthetics and the merits of an object for its own sake."

The channel launched on March 12, 2006 as Treasure HD; much of its programming and its name licensed from Rainbow Media, original owners of the now defunct Voom HD Networks. Like its American counterpart, the channel originally focused on factual art-based programming. When the American version ceased broadcasting in 2009, the Canadian channel broadened its programming to include live musical performance series and films.

TV Channel 16/12

TV channel 16/12 — is the only independent news TV channel in Kazakhstan.

Persecution of the Channel

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.

Channel (programming)

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.

Channel implementations

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.

Price channels

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".

Channel (digital image)

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.

Overview

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.
