Television set in the context of Computer game

A television show, TV program (British English: programme), or simply a TV show, is the general reference to any content produced for viewing on a television set that is transmitted via over-the-air, satellite, and cable, or distributed digitally on streaming platforms. This generally excludes breaking news or advertisements that are aired between shows or between segments of a show. A regularly recurring show is called a television series, and an individual segment of such a series is called an episode. Content is produced either in-house on a television stage with multiple cameras or produced by contract with film production companies. Episodes are usually broadcast in annual sets, which are called seasons in North America and series in other regions. A one-off television show may be called a television special, while a show with a limited number of episodes is a miniseries. A television film, or telefilm, is a feature film produced for broadcast by a terrestrial or cable network.

Television shows by terrestrial and cable networks are most often scheduled for broadcast ahead of time and appear on electronic guides or other TV listings. The rise of streaming television, however, has made television schedules less relevant than in earlier decades. Some programming may be aired live—that is, events are broadcast at the time they happen rather than at a later time or date—but the vast majority of programming is produced ahead of time. Originally, viewers had no practical way to record a show for later viewing; this changed with the advent of home video, first in the form of videotape recorded on VCRs and later in the form of digital video recorders. Cable television providers began offering certain programming "pay-per-view" or on-demand, with viewers paying a one-time fee to watch a program at a time of their own choosing. Streaming television allows viewers to watch programming at any time with a subscription to the OTT platform service.

A video game, computer game, or simply game, is an electronic game that involves interaction with a user interface or input device (such as a joystick, controller, keyboard, or motion sensing device) to generate visual feedback from a display device, most commonly shown in a video format on a television set, computer monitor, flat-panel display or touchscreen on handheld devices, or a virtual reality headset. Most modern video games are audiovisual, with audio complement delivered through speakers or headphones, and sometimes also with other types of sensory feedback (e.g., haptic technology that provides tactile sensations). Some video games also allow microphone and webcam inputs for in-game chatting and livestreaming.

Video games are typically categorized according to their hardware platform, which traditionally includes arcade video games, console games, and computer games (which includes LAN games, online games, and browser games). More recently, the video game industry has expanded onto mobile gaming through mobile devices (such as smartphones and tablet computers), virtual and augmented reality systems, and remote cloud gaming. Video games are also classified into a wide range of genres based on their style of gameplay and target audience.

A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms on an oscilloscope, a frame of video on an analog television set (TV), digital raster graphics on a computer monitor, or other phenomena like radar targets. A CRT in a TV is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term cathode ray was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons.

In CRT TVs and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster. In color devices, an image is produced by controlling the intensity of each of three electron beams, one for each additive primary color (red, green, and blue) with a video signal as a reference. In modern CRT monitors and TVs the beams are bent by magnetic deflection, using a deflection yoke. Electrostatic deflection is commonly used in oscilloscopes.

A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information that is supplied has an electrical signal the display is called an electronic display.

Common applications for electronic visual displays are television sets or computer monitors.

Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter.

A satellite receiver decodes the desired television program for viewing on a television set. Receivers can be external set-top boxes, or a built-in television tuner. Satellite television provides a wide range of channels and services. It is usually the only television available in many remote geographic areas without terrestrial television or cable television service. Different receivers are required for the two types. Some transmissions and channels are unencrypted and therefore free-to-air, while many other channels are transmitted with encryption. Free-to-view channels are encrypted but not charged-for, while pay television requires the viewer to subscribe and pay a monthly fee to receive the programming.

An over-the-top media service, also known as over-the-top television (OTT), is a digital distribution service of video and audio delivered directly to viewers via the public Internet, rather than through an over-the-air, cable, satellite, or IPTV provider. The term is synonymous with streaming platform.

OTT services may be subscription-based or free, and are typically accessed via television sets with integrated Smart TV platforms, streaming devices such as Apple TV, Amazon Fire TV and Roku, video game consoles, websites on personal computers, and apps on smartphones and tablets.

Multi-monitor, also called multi-display and multi-head, is the use of multiple physical display devices, such as monitors, televisions, and projectors, in order to increase the area available for computer programs running on a single computer system. Research studies show that, depending on the type of work, multi-head may increase the productivity by between 50 and 70 percent.

Video art is an art form which relies on using video technology as a visual and audio medium. Video art emerged during the late 1960s as new consumer video technology such as video tape recorders became available outside corporate broadcasting. Video art can take many forms: recordings that are broadcast; installations viewed in galleries or museums; works either streamed online, or distributed as video tapes, or on DVDs; and performances which may incorporate one or more television sets, video monitors, and projections, displaying live or recorded images and sounds.

Video art is named for the original analog video tape, which was the most commonly used recording technology in much of the form's history into the 1990s. With the advent of digital recording equipment, many artists began to explore digital technology as a new way of expression. Video art does not necessarily rely on the conventions that define theatrical cinema. It may not use actors, may contain no dialogue, and may have no discernible narrative or plot. Video art also differs from cinema subcategories such as avant garde cinema, short films, and experimental film.

An entertainment center (or centre), also known as an entertainment complex or a home entertainment center, is a piece of furniture designed to house consumer electronic appliances and components. It is sometimes a large cabinet with an exterior styled to appear like upscale furniture and an interior dedicated to electronic gear, such as home audio, television sets and video game equipment.

Antique or modern reproduction armoires or standing cabinets are used for entertainment centers, as are shelves and shelving systems. Part of the purpose of an entertainment center is to neatly house the many wires and cables that are associated with audio and video components, and they often contain dedicated areas (either drawers or other spaces) for storage of records, videotapes, CDs and/or DVDs.

A remote control, also known colloquially as a remote or clicker, is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other digital home media appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside.

Early television remote controls (1956–1977) used ultrasonic tones. Present-day remote controls are commonly consumer infrared devices which send digitally coded pulses of infrared radiation. They control functions such as power, volume, channels, playback, track change, energy, fan speed, and various other features. Remote controls for these devices are usually small wireless handheld objects with an array of buttons. They are used to adjust various settings such as television channel, track number, and volume. The remote control code, and thus the required remote control device, is usually specific to a product line. However, there are universal remotes, which emulate the remote control made for most major brand devices.

A scan line (also scanline) is one line, or row, in a raster scanning pattern, such as a line of video on a cathode-ray tube (CRT) display of a television set or computer monitor.

On CRT screens the horizontal scan lines are visually discernible, even when viewed from a distance, as alternating colored lines and black lines, especially when a progressive scan signal with below maximum vertical resolution is displayed. This is sometimes used today as a visual effect in computer graphics.

An electron gun (also called electron emitter) is an electrical component in some vacuum tubes that produces a narrow, collimated electron beam that has a precise kinetic energy.

The largest use is in cathode-ray tubes (CRTs), used in older television sets, computer displays and oscilloscopes, before the advent of flat-panel displays. Electron guns are also used in field-emission displays (FEDs), which are essentially flat-panel displays made out of rows of extremely small cathode-ray tubes. They are also used in microwave linear beam vacuum tubes such as klystrons, inductive output tubes, travelling-wave tubes, and gyrotrons, as well as in scientific instruments such as electron microscopes and particle accelerators.

An electronic visual display is a display device that can display images, video, or text that is transmitted electronically. Electronic visual displays include television sets, computer monitors, and digital signage. They are ubiquitous in mobile computing applications like tablet computers, smartphones, and information appliances. Many electronic visual displays are informally referred to as screens, and those that also contain some means of touch input are called touchscreens.

Starting in the early 2000s, flat-panel displays began to dominate the industry, as cathode-ray tubes (CRT) were phased out, especially for computer applications. Starting in the mid 2010s, curved display panels began to be used in televisions, computer monitors, and smartphones.
