C Channel

C Channel was a Canadian premium television service specialising in arts programming. It was one of Canada's first licensed "pay TV" channels when it began in 1983 but it ended in failure within months.

History

Toronto-based company Lively Arts Market Builders Inc. was one of several companies that received a licence from the Canadian Radio-television and Telecommunications Commission (CRTC) to provide a subscription television service for Canadian cable companies. The company's offering, C Channel, would feature artistic content such as theatrical, opera and ballet performances. This format was distinct from the other new pay-movie services, First Choice and Superchannel.

C Channel, First Choice and Superchannel began their broadcasts on 1 February 1983. C Channel's President Edgar Cowan predicted 200,000 subscribers and financial equilibrium within a year.

Programming

C Channel was required as a condition of licence from the CRTC to spend no less than 20% of its revenues and 50% of its expenditures on Canadian produced programming. The channel had planned to spend $4 million (CA$) in production during its initial seven months of broadcasting.

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.

Channel V

Channel V (styled Channel [V]) is the brand name for multiple international music television networks owned by STAR TV and Fox International Channels, fully owned subsidiaries of 21st Century Fox.

Channel V Asia

Channel V Asia is the flagship of the Channel V network .It was founded after MTV Asia parted ways with the STAR TV Network. It was produced and operated from Hong Kong from 1 January 1994 until 1 January 2002, after which operations were shifted to Malaysia with some aspects still operating in Hong Kong. It was branded by Martin Lambie-Nairn. Since 1 January 2008, Channel V International has moved back to its original studio in Hong Kong, which is also the same studio of Channel V China and Taiwan.

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".
