VOB stands for Video Object. It is a file format used in DVD-Video media to store and stream audio, video, and other related data. VOB files are essentially MPEG-2 system streams that contain audio, video, and subtitle streams multiplexed together. They are the main container format used in DVDs.
A VOB file is typically a large file that represents a single video title, such as a movie or an episode of a TV series, stored on a DVD disc. It contains the compressed audio and video data intended for playback on a DVD player or a computer with DVD playback capabilities.
The VOB format supports various audio codecs, such as Dolby Digital and DTS, as well as different video codecs like MPEG-2. It can also include subtitle streams that allow for displaying subtitles or captions during playback.
When a DVD is played, the VOB files are accessed and decoded by the DVD player software or hardware. The audio and video streams are decompressed, synchronized, and presented to the user as a coherent audiovisual experience.
In summary, VOB is a file format specifically designed for storing and playing back video content on DVDs. It contains audio, video, and subtitle streams multiplexed together in a compressed format, allowing for high-quality playback on compatible devices.
