The DVD (Digital Versatile Disc) video format refers to the storage and playback standard for digital video content on optical discs. DVDs use the MPEG-2 compression standard for video and various audio codecs, allowing for high-quality video and audio playback. DVDs typically store video, audio, and subtitle tracks in a structured format that includes menus and chapters, making them suitable for home entertainment systems. While DVDs have been largely superseded by digital streaming services, they remain a common and accessible medium for distributing and archiving video content.
