CJNT-DT

CJNT-DT, virtual channel 62 (UHF digital channel 49), is a City owned-and-operated television station located in Montreal, Quebec, Canada. The station is owned by Rogers Media, a division of Rogers Communications (through its Rogers Broadcasting Limited division). CJNT's transmitter is located at Mount Royal Park, near Downtown Montreal. On Shaw Direct, the channel is available on 366 (Classic) or 097 (Advanced), and in high definition on channel 046 (Classic) or 546 (Advanced). This station can also be seen on Rogers Cable (corporate sister through parent company Rogers Communications) channel 122, Vidéotron cable channel 14 and in high definition on digital channel 614.

Prior to being acquired by Rogers in 2013, CJNT was a multicultural station throughout its existence.

History

The station signed on the air on September 8, 1997, but had its roots in the 1980s as La Télévision Ethnique du Québec (TEQ), a public access ethnic cable channel. It had plans on moving over-the-air as early as the early 1990s, but was dogged by financial problems. Even after it signed on, its finances were in such a state that it never signed on earlier than noon. Part of the problem was that its effective radiated power was only 11 kilowatts, easily the weakest full-power station in Montreal and one of the weakest in North America – roughly on the same level as low-powered UHF stations in the United States. This effectively limited its over-the-air footprint to the Island of Montreal, Jésus Island and a few areas on the mainland. Most viewers could only get a clear picture on cable.

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.
