Standard DVD Authoring and Recording SDK
Multiple PGC Title support
A video Title structure defined in DVD Spec may consist of at least one PGC (Program Chain). A PGC is a segment of video stream, and the presentation of a PGC always starts at 0 time code. When there is only one PGC in the title structure, this PGC is named as Sequential PGC, and the title, therefore, is called One_Sequential_PGC_Title. A sequential PGC consists of at least one Cell structure, also known as 'Chapter'. Chapters can be browsed during title presentation, by pressing 'Next/Prev' keys on the remote controller.
Title
The Title is called Multi_PGC_Title when it contains more
than one PGC. PGC's can be presenting in pre-defined order, but while
playing from one PGC to another, it will display noticeable seamed
transition. The 'Next/Prev' keys on the remote controller may be used to
browse PGC streams only if the Next_PGCN, Prev_PGCN commands have been
assigned during the authoring stage.
