A type of packaging often used for multiple-CD sets. Digipacks are made from reinforced cardboard that folds out (like an old gatefold LP) to reveal the disc(s) in plastic trays fixed to the cardboard outer sleeve. Often Digipacks are protected from wear and tear by an additional outer sleeve or slipcase. See also Amaray.Back to top
A music product that combines audio and video content on a single disc. In addition to a full album on the CD player side, the DVD player side provides the full album in enhanced sound (such as Surround Sound and/or DVD-Audio or LPCM stereo), and also includes a range of content such as music videos, interviews, photo galleries, web links, concert footage or lyrics.Back to top
An audio format that provides music in multi-channel surround sound. Whereas a standard DVD, carrying both picture and sound, uses digital compression to store all the information on the disc, the DVD-A format takes advantage of the greater storage capacity of DVD compared with CD to provide up to six channels of uncompressed audio. Its main rival Super-Audio CD (SACD) is a modified CD format, not a DVD. See also Introduction to DVD-Audio.Back to top
The official term (sometimes abbreviated to 'PCM') for the high-quality stereo soundtrack found on most music DVDs. DVD supports higher-resolution versions of LPCM than CD, the most common of which is 48kHz/16 bit (as opposed to CD's 44.1kHz/16 bit). LPCM Stereo is 'uncompressed', offering higher quality than such 'compressed' alternatives as Dolby Stereo.Back to top
An informal term to describe a DVD release with significant extra material in addition to the main feature. Often these are two-disc sets, with the second disc devoted entirely to the bonus material.Back to top
