Abstract

This chapter focuses on digital versatile disc, popularly known as DVD. DVD is an advanced optical disc technology that is rapidly replacing video home system (VHS) tapes, laser discs, video game cartridges, audio Compact Discs (CD), and CD-ROMs. DVD technology is faster and provides a storage capacity that is about 6 to 7 times greater than the CD technology. Both have the same aerial space—4.75 inches and 3.1 inches, 1.2mm thick. DVD technology provides multiple languages on movies with multiple language subtitles. Since a beam of laser light touches the data portion of a DVD disc, it is never touched by a mechanical part when played, thus eliminating wear. There are three application formats of DVD—namely, DVD-Video, DVD-Audio, and DVD-ROM. The DVD-Video format which is commonly called “DVD” is by far the most widely known. DVD-Video is principally a video and audio format used for movies, music concert videos, and other video-based programming. The DVD-Audio format features high-resolution, two-channel stereo and multi-channel (up to six discrete channels) audio. DVD-ROM is a data storage format developed with significant input from the computer industry. It may be viewed as a fast, large-capacity CD-ROM. It is played back in a computer's DVD-ROM drive. It allows for data archival and mass storage as well as interactive and/or web-based content.
