Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types.

Dolby Digital, originally synonymous with Dolby AC-3, is the name for a family of audio compression technologies developed by Dolby Laboratories. Called Dolby Stereo Digital until 1995, it is lossy compression. The first use of Dolby Digital was to provide digital sound in cinemas from 35 mm film prints. It has since also been used for TV broadcast, radio broadcast via satellite, digital video streaming, DVDs, Blu-ray discs and game consoles.

A boombox is a transistorized portable music player featuring one or two cassette tape players/recorders and AM/FM radio, generally with a carrying handle. Beginning in the mid 1990s, a CD player was often included. Sound is delivered through an amplifier and two or more integrated loudspeakers. A boombox is a device typically capable of receiving radio stations and playing recorded music. Many models are also capable of recording onto cassette tapes from radio and other sources. In the 1990s, some boomboxes were available with MiniDisc recorders and players. Designed for portability, boomboxes can be powered by batteries as well as by line current. The boombox was introduced to the American market during the late 1970s. The desire for louder and heavier bass led to bigger and heavier boxes; by the 1980s, some boomboxes had reached the size of a suitcase. Some larger boomboxes even contained vertically mounted record turntables. Most boomboxes were battery-operated, leading to extremely heavy, bulky boxes.

The LaserDisc (LD) is a home video format and the first commercial optical disc storage medium, initially licensed, sold and marketed as MCA DiscoVision in the United States in 1978. Its diameter typically spans 30 cm (12 in). Unlike most optical-disc standards, LaserDisc is not fully digital, and instead requires the use of analog video signals.

In telecommunications and computing, bit rate is the number of bits that are conveyed or processed per unit of time.

In computing, an optical disc drive is a disc drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, but recent drives can both read and record, also called burners or writers. Compact discs, DVDs, and Blu-ray discs are common types of optical media which can be read and recorded by such drives.

The preservation of optical media is essential because it is a resource in libraries, and stores audio, video, and computer data to be accessed by patrons. While optical discs are generally more reliable and durable than older media types, environmental conditions and/or poor handling can result in lost information.

<span class="mw-page-title-main">PSX (digital video recorder)</span> Sony digital video recorder with a integrated PlayStation 2

The PSX is a Sony digital video recorder with a fully integrated PlayStation 2 home video game console. It was released in Japan on December 13, 2003. Since it was designed to be a general-purpose consumer video device, it was marketed by the main Sony Corporation instead of Sony Computer Entertainment and does not carry the usual PlayStation branding. Initial sales were strong, with the console selling 100,000 units during its first week, thus selling out. Its high cost, however, resulted in poor sales later on, prompting Sony to cancel plans to release the PSX outside Japan. After the price had been lowered in September 2004, sales increased again.

A digital copy is a commercially distributed computer file containing a media product such as a film or music album. The term contrasts this computer file with the physical copy with which the digital copy is usually offered as part of a bundle. It allows the disc's purchaser to acquire a single copy of the film on a digital device such as a personal computer, smartphone, tablet computer, or digital media player, and view it on those devices without requiring access to the physical media. "Digital copy" is also commonly referred to as "Digital HD".
