Abstract: A DVD authoring system in a processor-based system removes an author from consideration of the DVD Specification during authoring. According to a preferred embodiment, the authoring system provides an authoring engine having an interactive graphical authoring interface, a data management engine, an emulator, a compiler, a multiplexer and a simulator. Using summary authoring data, the compiler builds a skeleton-form PGC layout structure comprising control PGC abstractions and router PGC abstractions. The compiler then resolves the PGC abstractions according to source-target connections. During playback on a DVD player, the PGC abstractions form elements in a connection-switching abstraction superstructure. Accordingly, in response to DVD-consumer and other control events, a source PGC preferably determines target PGC information and then transfers control, via virtual connections through necessary router PGC abstractions, to a target PGC abstraction. The target PGC abstraction then correspondingly initiates playback of a movie chapter or displays a menu.

Abstract translation: 基于处理器的系统中的DVD制作系统在创作过程中将作者从DVD规范的考虑中删除。 根据优选实施例，创作系统提供具有交互式图形创作界面，数据管理引擎，仿真器，编译器，复用器和模拟器的创作引擎。 使用摘要创作数据，编译器构建一个骨架形式的PGC布局结构，包括控制PGC抽象和路由器PGC抽象。 编译器然后根据源目标连接解析PGC抽象。 在DVD播放器播放期间，PGC抽象在连接切换抽象上层建筑中形成元素。 因此，响应于DVD消费者和其他控制事件，源PGC优选地确定目标PGC信息，然后经由必要的路由器PGC抽象的虚拟连接将控制转移到目标PGC抽象。 目标PGC抽象然后相应地启动电影章节的回放或显示菜单。
