How do the interactive features work?
DVD-Video players (and software DVD-Video navigators) support a command set that provides rudimentary interactivity. The main feature is menus, which are present on almost all discs to allow content selection and feature control. Each menu has a still-frame graphic and up to 36 highlightable, rectangular “buttons” (only 12 if widescreen, letterbox, and pan & scan modes are used). Remote control units have four arrow keys for selecting onscreen buttons, plus numeric keys, select key, menu key, and return key. Additional remote functions may include freeze, step, slow, fast, scan, next, previous, audio select, subtitle select, camera angle select, play mode select, search to program, search to part of title (chapter), search to time, and search to camera angle. Any of these features can be disabled by the producer of the disc.

Each menu has a still or motion background and up to 36 highlightable, rectangular “buttons” (only 12 if widescreen, letterbox, and pan & scan modes are used). Remote control units have up/down/left/right arrow keys for selecting onscreen buttons, along with numeric keys, a select (enter) key, a menu key, a top menu (title) key, and a return key.

Commands can also control player settings, jump to different parts of the disc, and control presentation of audio, video, sub-picture, camera angles, and so on. The command set enables relatively sophisticated discs, such as games or interactive educational programs.
