CD Video (also known as CDV, CD-V, or CD+V) is a format of optical media disc that was introduced in 1987 that combines the technologies of standard compact disc and LaserDisc. CD-V discs are the same size as a standard 12 cm (4.7 in) audio CD, and contain up to 20 minutes' worth of CD audio that can be played on any audio CD player. It also contains up to 5 minutes of LaserDisc video information with digital CD-quality sound, which can be played back on a newer LaserDisc player capable of playing CD-V discs or CD-V-only players.[1]
The "CD Video" brand was also used to market some 20 cm (7.9 in) and 30 cm (12 in) LaserDiscs which included a digital soundtrack[2] but no CD-compatible content.
