Reference excerpt

Canada is served by various multichannel television services, including cable television systems, two direct-broadcast satellite providers, and various other wireline IPTV and wireless MMDS video providers. Canadian multichannel television providers are legally referred to as broadcast distribution undertakings (BDUs). They must be licensed by the Canadian Radio-television and Telecommunications Commission (CRTC) and comply with its policies, including those on the packaging of their services. Additionally, the CRTC licences specialty channels; licensing was previously mandatory for all services, and restrictions were placed on their content in order to discourage direct competition in certain categories. The CRTC began to phase out these policies by the 2010s, and in 2012, it began exempting networks with less than 200,000 subscribers, as well as certain ethnic services not broadcasting in Canada's official or indigenous languages, from formal licensing. Per its New Media exemption order, the CRTC does not regulate internet television or video content delivered over the public internet, such as over-the-top subscription services. Some of the CRTC's policies in regard to multichannel television are intended to protect and encourage the production of Canadian content, and prevent foreign broadcasters from unduly harming domestic outlets. U.S. and international channels can be authorized for distribution in Canada if they are deemed to not be unduly competitive to Canadian outlets (although their programming may be affected by differing broadcast rights). Affiliates of the U.S. ABC, CBS, Fox, NBC, and PBS networks are also readily available in Canada, but their programming is subject to a CRTC rule known as simultaneous substitution (or simsub), which gives Canadian broadcast stations within a viewer's market the right to require that U.S. feeds of programs be substituted by BDUs with their own if they are broadcasting the same program in simulcast. This rule serves to protect Canadian advertising revenue. The majority of Canada's multichannel television industry is dominated by vertically integrated companies and their respective services, including Bell Canada's Bell Satellite TV satellite and fibreoptic Fibe TV IPTV services, Rogers Communications' cable systems (primarily in Ontario and Atlantic Canada), Shaw Communications' cable systems (primarily in Western Canada; the Shaw family also owns Corus Entertainment, a major operator of Canadian specialty channels), Telus' Optik TV and Vidéotron (which operates mainly in its home province of Quebec, and is owned by local conglomerate Quebecor).

Worked examples

Example 1 — a first encounter with Multichannel television in Canada

Start with the simplest possible case. Write down what Multichannel television in Canada claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Multichannel television in Canada before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Multichannel television in Canada ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Multichannel television in Canada

In research: Multichannel television in Canada appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Multichannel television in Canada in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Multichannel television in Canada is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cable television in Canada, Mass media regulation in Canada, Satellite television, so understanding it makes those chapters shorter.
In everyday life: Look for Multichannel television in Canada outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
