The book type is a field of four bits at the start of every DVD (in the physical format information section of the control data block) that indicates what the physical format of the disc is.
In information security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations.
In digital recording, audio signals picked up by a microphone or other transducer or video signals picked up by a camera or similar device are converted into a stream of discrete numbers, representing the changes over time in air pressure for audio, and chroma and luminance values for video, then recorded to a storage device.
DVD (an abbreviation of "digital video disc" or "digital versatile disc") is a digital optical disc storage format invented and developed by Philips and Sony in 1995.
A DVD player is a device that plays DVD discs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards.
DVD recordable and DVD rewritable refer to part of optical disc recording technologies.
DVD+R DL (DL stands for Double Layer) also called DVD+R9, is a derivative of the DVD+R format created by the DVD+RW Alliance.
DVD-R DL (DL stands for Dual Layer), also called DVD-R9, is a derivative of the DVD-R format standard. DVD-R DL discs hold 8.5 GB by utilizing two recordable dye layers, each capable of storing a little less than the 4.7 gigabyte (GB) of a single layer disc, almost doubling the total disc capacity. Discs can be read in many DVD devices (older units are less compatible) and can only be written using DVD-R DL compatible recorders. It is part of optical disc recording technologies for digital recording to optical disc. DVD-R DL has compatibility issues with legacy DVD-ROM drives known as pickup head overrun. To avoid this issue, the two layers of the disc need to be equally recorded. But this is a contradiction with the sequential nature of the DVD recording. Thus DVD Forum under Pioneer's lead developed a technology known as Layer Jump Recording (LJR), which incrementally record smaller sections of each layer to maintain compatibility with DVD-ROM drives. DVD-R DL media has been discontinued by most manufacturers. DVD+R DL is dominating the market for dual layered media.
The gigabyte is a multiple of the unit byte for digital information.
Layer Jump Recording (LJR) is a writing method used for DVD-R DL (Dual Layer).
MiniDVD (also Mini DVD or miniDVD) is a DVD disc which is in diameter.
MultiLevel Recording (ML) (also known as M-ary) was a technology originally developed by Optex Corporation and promoted by Calimetrics to increase the storage capacity of optical discs.
Opposite Track Path (OTP) is a technique used in optical technology, which when correctly implemented allows faster (though not un-noticeable) switching from layer 0 to layer 1.
In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc which encodes binary data (bits) in the form of pits (binary value of 0 or off, due to lack of reflection when read) and lands (binary value of 1 or on, due to a reflection when read) on a special material (often aluminium) on one of its flat surfaces.
Optical disc authoring requires a number of different optical disc recorder technologies working in tandem, from the optical disc media to the firmware to the control electronics of the optical disc drive.
Koninklijke Philips N.V. (Philips, stylized as PHILIPS) is a Dutch multinational technology company headquartered in Amsterdam currently focused in the area of healthcare.
commonly referred to as Pioneer, is a Japanese multinational corporation based in Tokyo, Japan that specializes in digital entertainment products.
