Triple Play (optical discs)

Last updated

Triple Play is a form of home entertainment optical disc distribution which provides the buyer with a film or TV series in three different formats in a single keep case. The formats are Blu-ray Disc, DVD, and a digital copy. In some cases, an Ultraviolet copy will be included in place of a DVD.

Home video is pre-recorded video media that is either sold, rented or streamed for home entertainment. It is a type of home media. The term originates from the VHS/Betamax era, when the predominant medium was videotape, but has carried over into optical disc formats like DVD and Blu-ray and, since the 2000s, into methods of digital distribution such as Netflix, Hulu, and Amazon Video.

Optical disc flat, usually circular disc which encodes binary data

In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc which encodes binary data (bits) in the form of pits and lands on a special material on one of its flat surfaces. The encoding material sits atop a thicker substrate which makes up the bulk of the disc and forms a dust defocusing layer. The encoding pattern follows a continuous, spiral path covering the entire disc surface and extending from the innermost track to the outermost track. The data is stored on the disc with a laser or stamping machine, and can be accessed when the data path is illuminated with a laser diode in an optical disc drive which spins the disc at speeds of about 200 to 4,000 RPM or more, depending on the drive type, disc format, and the distance of the read head from the center of the disc. Most optical discs exhibit a characteristic iridescence as a result of the diffraction grating formed by its grooves. This side of the disc contains the actual data and is typically coated with a transparent material, usually lacquer. The reverse side of an optical disc usually has a printed label, sometimes made of paper but often printed or stamped onto the disc itself. Unlike the 3½-inch floppy disk, most optical discs do not have an integrated protective casing and are therefore susceptible to data transfer problems due to scratches, fingerprints, and other environmental problems.

Keep case

A keep case or poly-box is a type of packaging, most commonly used with DVDs.

    DVD-Video consumer video format used to store digital video on DVD discs

    DVD-Video is a consumer video format used to store digital video on DVD discs. DVD-Video was the dominant consumer home video format in Asia, North America, Europe, and Australia in the 2000s until it was supplanted by the high-definition Blu-ray Disc. Discs using the DVD-Video specification require a DVD drive and an MPEG-2 decoder. Commercial DVD movies are encoded using a combination MPEG-2 compressed video and audio of varying formats. Typically, the data rate for DVD movies ranges from 3 Mbit/s to 9.5 Mbit/s, and the bit rate is usually adaptive. DVD-Video was first available in Japan on November 1, 1996.

"Digital copy" is also commonly referred to as "Digital HD".
