Xbox (DVD) Two sets of media descriptors are used. Initially, and on typical DVD-ROM drives, only a short partition containing a brief DVD Video can be seen. The lead-out section of the disk stores a second set of media descriptors describing the bounds of the main partition. It also contains a partially-encrypted "security sector" used for ...
A sector is the primary data structure on a CD-ROM accessible to external software (including the OS). On a Mode-1 CD-ROM, each sector contains 2048 bytes of user-data (content) and 304 bytes of structural information. Among other things, the structural information consists of the sector number, the sector's relative and absolute logical position
DVD-ROM and DVD-R(W) use one encoding, DVD-RAM and DVD+R(W) uses another: Capacity: 4.7 GB (single-sided, single-layer – common) 8.5 GB (single-sided, double-layer) 9.4 GB (double-sided, single-layer) 17.08 GB (double-sided, double-layer) Up to four layers are possible in a standard form DVD. Read mechanism: 650 nm laser, 10.5 Mbit/s (1×)
Writing a DVD at 1× (1 385 000 bytes per second) [5] is approximately 9 times faster than writing a CD at 1× (153 600 bytes per second). [6] However, the actual speeds depend on the type of data being written to the disc. [6] For Blu-ray discs, 1× speed is defined as 36 megabits per second (Mbit/s), which is equal to 4.5 megabytes per second ...
The DVD-ROM's main-data (§16 [3]), which are consecutive logical blocks of 2048 bytes, are structured according to the DVD-Video format. The DVD-Video contains (besides others) an MPEG program stream which consists of so-called Packs. If CSS is applied to the disc then a subset of all Packs is encrypted with a title-key.
DVD+R DS (DS stands for Double Side) a sub category of DVD+R. It can only be written once. It can only be written once. (DVD+RW can be written, erased and rewritten) [ 1 ] [ 2 ]
Standard definition VCR replacement DVD video recorders typically has a set of standard recording modes for fitting 1, 2, 4, 6, 8, 10 hour modes (XP, SP, LP, EP, SLP, SEP, respectively) on single layer 12 cm discs (DVD5). [8] These modes are comparable to those found on VHS VCRs using standard 120-tapes, having SP, LP, SLP modes of 2, 4, 6 hour.
