public enum DVDMenu

Fields

Title = 0

The title selection menu allowing users to choose from available titles on the disc.

The title menu is typically the main entry point for selecting different programs or features on a DVD. For movie DVDs, this might include the main feature, deleted scenes, documentaries, or other bonus content. For TV series DVDs, this would list the available episodes.

This menu often appears as the first interactive screen after any automatic introductory sequences and serves as the primary navigation hub for the disc's content.

Root = 1

The root menu providing access to the main navigation options.

The root menu serves as the primary navigation interface, often providing access to play options, scene selection, setup menus, and special features. This is typically what users access when pressing the "Menu" button during playback.

The root menu may be context-sensitive, showing different options depending on whether it's accessed from the main menu system or during title playback. It serves as a central hub for navigating the DVD's features and content.

Subpicture = 2

The subpicture (subtitle) configuration menu for selecting subtitle options.

The subpicture menu allows users to configure subtitle and caption settings. This includes enabling or disabling subtitles, selecting from available subtitle languages, and sometimes choosing between different subtitle formats (such as regular subtitles versus closed captions for the hearing impaired).

DVDs can contain multiple subtitle streams in different languages, and this menu provides the interface for selecting the desired option. The availability of subtitle options varies by disc and region.

Audio = 3

The audio configuration menu for selecting audio tracks and settings.

The audio menu provides options for selecting different audio tracks available on the DVD. This commonly includes different languages, audio formats (such as stereo versus surround sound), or commentary tracks featuring directors, actors, or other production personnel.

Many DVDs include multiple audio options such as: - Different language dubs - Various surround sound formats (Dolby Digital, DTS, etc.) - Commentary tracks - Descriptive audio for visually impaired viewers

Angle = 4

The angle selection menu for choosing different camera angles.

The angle menu allows viewers to switch between different camera angles for scenes that were filmed from multiple perspectives. This feature is relatively rare and is typically found on special edition DVDs, concert recordings, or sports events.

Multi-angle content allows the DVD author to include several synchronized video streams that viewers can switch between in real-time. When available, viewers can see the same scene from different viewpoints, such as different camera positions at a concert or alternate takes of a movie scene.

Chapter = 5

The chapter selection menu for navigating to specific scenes or segments.

The chapter menu provides direct access to specific scenes or segments within a title. Chapters divide the content into logical sections, making it easy to jump to particular parts of a movie, specific scenes, or individual songs in a concert.

Chapter menus typically display: - Thumbnail images or titles for each chapter - Chapter numbers and sometimes timestamps - Descriptive names for each segment This allows for quick navigation without having to fast-forward through content.

Remarks

DVD menus provide interactive navigation and configuration options for DVD content. Different menu types serve specific purposes in the DVD navigation structure, allowing users to access various features and settings. These menus are defined by the DVD-Video specification and are standard across all compliant DVD players.

The availability of specific menu types depends on how the DVD was authored. Not all DVDs will include all menu types, and some may have limited or no menu functionality. When attempting to access a menu that doesn't exist on a particular DVD, the player typically either does nothing or returns to the current playback state.
