What is DVD?
DVD, which stands for Digital Video Disc, Digital Versatile Disc, or nothing, depending on whom you ask, is the next generation of optical disc storage technology. It’s essentially a bigger, faster CD that can hold video as well as audio and computer data. DVD aims to encompass home entertainment, computers, and business information with a single digital format, eventually replacing audio CD, videotape, laserdisc, CD-ROM, and perhaps even video game cartridges. DVD has widespread support from all major electronics companies, all major computer hardware companies, and about half of the major movie and music studios, which is unprecedented and says much for its chances of success (or, pessimistically, the likelihood of it being forced down our throats). It’s important to understand the difference between DVD-Video and DVD-ROM. DVD-Video (often simply called DVD) holds video programs and is played in a DVD player hooked up to a TV. DVD-ROM holds computer data and is read by a DVD-ROM driv
DVD is the term which describes the next generation CD-ROM standard. DVD was developed from the start to be a unified format for movies, audio, and computer storage. DVD disks are the same size as audio CD and CD-ROM discs, which makes DVD players backward-compatible with existing CD and CD-ROM disks. DVD was also developed to support future write-once (DVD-R) and read/write (DVD-RAM) discs. DVD is supported by a consortium of major entertainment, consumer electronics and computer makers including, Fleming Multimedia Computers (part of the Fleming Multimedia Group), Sigma Designs, Toshiba, Time-Warner, MGM, Columbia Tri-Star, Microsoft, Sony, Philips, Matsushita, IBM, JVC, Hitachi, Mitsubishi, Pioneer, Thomson, and many others. A DVD-ROM drive installed in a personal computer offers massive high-speed storage capacity of 17 gigabytes, which is over 25 times the capacity of a traditional CD-ROM. The same drive, which looks like a conventional CD-ROM drive, can support standard CD-ROM an
A.DVD looks like a Compact Disc. But instead of just playing music, it delivers more than two hours of high-quality video – for movies, children’s programming or music concerts. A single-sided, single-layer DVD can contain up to 133 minutes of video enough to handle 95% of all movies, without the interruption of flipping the disc over or changing discs. The optical disc technology of DVD completely outperforms videotape. For example, you can play a DVD hundreds of times, without picture degradation. You can go from scene to scene in a split second without rewinding! Because DVDs can deliver more than 500 lines of horizontal resolution, the picture detail is more than twice as good as a VCR. DVDs aren’t just for the eyes, they are truly music to your ears. They feature a new audio system: Dolby Digital multi-channel surround sound. Unlike Dolby Pro Logic sound, the new system is all-digital. Separate Left and Right Surround channels deliver pin-point accurate sound effects. Whats more,
DVD can stand for Digital Versatile Disk. An optical recording media similar to the familiar CD but having seven times its capacity on a single side. In television applications, DVDs are capable of carrying full-length commercial movies, plus additional material such as outtakes, director’s notes, movie trailers, etc. What is DVD-R and DVD-RW DVD-R is a non-rewriteable format and it is compatible with about 92% of all DVD Players and most DVD-ROMs. DVD-RW is a rewriteable format and it is compatible with about 75% of all DVD Players and most DVD-ROMs. These formats are supported by DVDForum.
