Key takeaways

TV accessory belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect TV accessory to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of TV accessory from memory before moving on to harder problems.

Reference excerpt

A television accessory (TV accessory) is an accessory that is used in conjunction with a television (TV) or other compatible display device and is intended to either improve the user experience or to offer new possibilities of using it.

History The first TV accessory with which owners could actively influence the content displayed on the screen in real time was the Magnavox Odyssey, the first commercial home video game console, released in September 1972 by Magnavox for a list price of $99.95. One of the first TV accessories that could record TV programs available to consumers was the Clie Pega-VR100K by Sony, released on October 9, 2003, for a list price of $479.99. As of 2017, TV accessories are a rapidly growing market which is expected to grow even more rapidly in the near future. Some of the most popular manufacturers of TV accessories include Sony, Magnavox, Philips, LG, Apple, Nvidia, Amazon, Samsung, and Google, as well as many independent third-party suppliers.

Types

Soundbars

A soundbar (also called sound bar or media bar) is a type of loudspeaker that projects audio from a wide enclosure. Soundbars are one of the most popular TV accessories because they are affordable, very easy to install and a relatively large upgrade compared to other accessories, offering much better sound than most integrated TV loudspeakers.

Universal remotes

A universal remote is a remote control that can be programmed to operate various brands of one or more types of consumer electronics devices. On May 30, 1985, Philips introduced the first universal remote (U.S. Pat. #4774511) under the Magnavox brand name. In 1985, Robin Rumbolt, William "Russ" McIntyre, and Larry Goodson with North American Philips Consumer Electronics (Magnavox, Sylvania, and Philco) developed the first universal remote control.

Streaming television

Streaming television is the digital distribution of television content, such as TV shows, as streaming video delivered over the Internet. Most TVs today are smart TVs, meaning that they can connect to the Internet to use different functions. However, since there are many different TV manufacturers that use different interfaces for these functions, this may be confusing for some users. A dedicated streaming box like an Apple TV, Google Chromecast, Amazon Fire TV Stick or PlayStation TV offers a universal user experience across all TV brands. An Android TV box like the Nvidia Shield TV can also run all Android apps on the Play Store and stream PC gaming content to the TV.

HDMI switches An HDMI switch (also known as HDMI switcher or HDMI switching box) is a device that accepts input from multiple HDMI sources and sends the signal you select to your HDTV via an HDMI cable. When they also support USB devices, they are KVM switches.

Home video game consoles

A home video game console is a type of video game console that is designed to be connected to a display device, such as a television, and an external power source as to play video games. In contrast to many other TV accessories that improve the user experience, a home video game console offers new possibilities of using a TV, meaning that users of such can not only determine what should be shown on the television screen, but also actively influence it in real time.

Worked examples

Example 1 — a first encounter with TV accessory

Start with the simplest possible case. Write down what TV accessory 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 TV accessory 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 TV accessory 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 TV accessory

In research: TV accessory 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 TV accessory 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: TV accessory is common in secondary-school and first-year university syllabi. It links to neighbouring topics Consumer electronics, Electronics industry, Multimedia, so understanding it makes those chapters shorter.
In everyday life: Look for TV accessory 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.
