Most DVD-authoring applications focus exclusively on video DVDs and do not support the authoring of DVD-Audio discs. Stand-alone DVD recorder units generally have basic authoring functions, though the creator of the DVD has little or no control over the layout of the DVD menus, which generally differ between models and brands.
Optical disc authoring, including CD, DVD, and Blu-ray Disc authoring, is the process of assembling source material—video, audio or other data—into the proper logical volume format to then be recorded ("burned") onto an optical disc (typically a compact disc or DVD).
Each sector (or "timecode frame") consists of a sequence of channel frames. These frames, when read from the disc, are made of a 24-bit synchronization pattern with the constant sequence 1000-0000-0001-0000-0000-0010, not present anywhere else on the disc, separated by three merging bits, followed by 33 bytes in EFM encoding, each followed by 3 merge bits.
A compressed audio optical disc, MP3 CD, or MP3 CD-ROM or MP3 DVD is an optical disc (usually a CD-R, CD-RW, DVD-R or DVD-RW) that contains digital audio in the MP3 file format. Discs are written in the " Yellow Book " standard data format (used for CD-ROMs and DVD-ROMs ), as opposed to the Red Book standard audio format (used for CD-DA audio CDs).
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 specifications created and updated by the DVD Forum are published as so-called DVD Books (e.g. DVD-ROM Book, DVD-Audio Book, DVD-Video Book, DVD-R Book, DVD-RW Book, DVD-RAM Book, DVD-AR (Audio Recording) Book, DVD-VR (Video Recording) Book, etc.).
The rotation speed of DVD at ×1 CAV (~580 rpm) is around three times as high as CD at ×1 (~200 rpm) Disc write time in table does not include overhead, leadout, etc. The following table describes the maximal speed of DVD-R and the relative typical write time for a full disc according to the reviews from cdrinfo.com and cdfreaks.com.
