DVD stands for Digital Versatile Disc. Due to wide spreading of this disk as a media for high-quality video distribution, DVD is often called Digital Video Disc. But most people just use the abbreviation - DVD without specifying what V is. A DVD disc and a CD disc look the same (both 120mm diameter). But that's the end of the "sameness". It's essentially a bigger (not in size, but capacity), faster CD that can hold cinema-like video, better-than-CD 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 all major movie and music studios. With this unprecedented support, DVD has become the most successful consumer electronics product of all time in less than three years of its introduction.

DVD glossary

Galois Field

Mathematical concept where the elements of the binary field GF(2m) are represented by 2m m-bit binary bytes, each expressible by an m-bit column vector. For example, GF(28) contains 256 eight-bit bytes. Named for the brilliant French mathematician Evariste Galois who developed the concept in the early 1830's. Killed in a duel at the age of 25, his work was unknown until Liouville published Galois' papers in 1846.

GB

Gigabyte, 1 GB equals 230 bytes or 1024 megabytes. Or, 1 GB may equal 109 bytes. Gb may denote gigabits.

There are 4 standard formats. D10 and D18 are not as common.

A DVD-5 (single sided) DVD-Video disc will hold nominally 133 minutes of high quality MPEG-2 encoded video, together with three surround-sound audio channels and four subtitle channels. (Without video compression one DVD-5 disc would hold only about 3 minutes of video).

A DVD-9 (dual layer) disc increases the playing time to 240 minutes of continuous video.

A DVD-10 (double sided) disc will hold a nominal 133 minutes on each side (ie 266 minutes in all), but the disc needs to be turned over to play the other side.

A DVD-18 (dual layer, doubled sided) disc can hold 240 minutes on each side and the disc also needs to be turned over to play the other side.

Most DVD is D9 or D5 format. DVD-Cloner can clone D9 to just ONE DVDr/rw disc (D5 format) without evident losing.
