[1.2] What are the features of DVD-Video?

• Over 2 hours of high-quality digital video (a double-sided, dual-layer disc can hold about 8 hours of high-quality video, or 30 hours of VHS quality video).
• Support for widescreen movies on standard or widescreen TVs (4:3 and 16:9 aspect ratios).
• Up to 8 tracks of digital audio (for multiple languages, commentaries, etc.), each with as many as 8 channels.
• Up to 32 subtitle/karaoke tracks.
• Automatic seamless branching of video (for multiple story lines or ratings on one disc).
• Up to 9 camera angles (different viewpoints can be selected during playback).
• On-screen menus and simple interactive features (for games, quizzes, etc.).
• Multilingual identifying text for title name, album name, song name, cast, crew, etc.
• Instant rewind and fast forward (no "be kind, rewind" stickers and threats on rental discs)
• Instant search to title, chapter, music track, and timecode.
• Durable (no wear from playing, only from physical damage).
• Not susceptible to magnetic fields. Resistant to heat.
• Compact size (easy to handle, store, and ship; players can be portable; replication is cheaper than tapes or laserdiscs).
• Noncomedogenic.

Note: Most discs do not contain all features (multiple audio/subtitle tracks, seamless branching, parental control, etc.), as each feature must be specially authored. Some discs may not allow searching or skipping.

Most players support a standard set of features:

• Language choice (for automatic selection of video scenes, audio tracks, subtitle tracks, and menus). *
• Special effects playback: freeze, step, slow, fast, and scan.

• Programmability (playback of selected sections in a desired sequence).
• Random play and repeat play.
• Digital audio output (PCM stereo and Dolby Digital).
• Recognition and output of DTS Digital Surround audio tracks.

* Must be supported by additional content on the disc.
