VOB file & its significance

VOB, short for Video Object, serves as a container format designed for storing various elements of DVD content, including audio, video, images, subtitles, DVD menus, navigation content, and streaming data. These DVD files can exist in both encrypted and unencrypted forms, with the default storage location being within the VIDEOS_TS folder found at the root of the DVD folder structure.

The VOB file format conforms to the MPEG program stream standard and is structured as MPEG-2 system streams. VOB video files are compatible with a wide range of media players, including VLC Media Player, Windows Media Player, Potplayer, GOM Player, KMPlayer, ALLPlayer, Elmedia, HandBrake, Pinnacle Studio, and more. They can also be played on DVD Players, provided that the BUP/IFO files necessary for DVD navigation are present.
