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

F1-Frame

Group of 24 8-bit bytes after scrambling and before CIRC encoding during a write operation. Alternatively, after CIRC decoding and before de-scrambling during read.

F2-Frame

Group of 32 8-bit bytes after scrambling and after CIRC encoding during a write operation. Alternatively, before CIRC decoding and de-scrambling during read.

F3-frame

Group of 33 8-bit bytes consisting of the F2-frame plus 8 subcode bits.

Father

The first electroformed part made from a glass master and containing a reversed data image of the final disc.

File

Named collection of information stored in one or more extents.

File Section

Part of the file that is stored in any one extent and identified by a descriptor in a directory.

Finalization

Action in which lead-in and lead-out areas are recorded that must be performed at the end of a recording operation if the disc is to be readable in a conventional drive. Also referred to as closure.

Flag

Bits appended to information that are used to indicate the status of that information.

Form 1

CD-ROM XA Mode 2 sector containing three levels of error correction for reliable retrieval of error- sensitive data.

Form 2

CD-ROM XA Mode 2 sector containing two levels of error correction for information tolerant of uncorrectable errors.

Format

Structure used to organize data for information storage and retrieval.

Frame

Information group containing data bytes along with other information such as sync, address, and parity bytes for error correction and detection.

Field
One half of a video frame, consisting of every other row (scan line).

File
A multiple of logical blocks on disk.

File System
Means of identifying files and their sector number on disc.

Frame
A complete, individual picture in a motion video.

Frame rate
The number of frames per second at which a video clip is displayed.

FPS
Frames Per Second. Rate at which motion video frames are displayed.

Full-Frame
Movies are shown theatrically in a widescreen presentation. One process of creating a widescreen film is to place "mattes" over the top and bottom of the 35 mm film frame (roughly 1.37:1) to alter the aspect ratio to 1.85:1 or other ratio. To avoid letterboxing bars on the top and bottom of a picture when displayed on a standard television, the original mattes are removed. Hence, the resulting video transfer shows more picture than was seen theatrically, and this process is called Full Frame. Often (erroneously) used interchangeably with pan-and-scan.

Full motion video
Video that plays back at thirty frames per second (NTSC) or 25 frames per second (PAL).
