Video Object (VOB) is a container format used in DVD-Video media, originally developed and maintained by the DVD Forum. It is primarily utilized within the DVD-Video structure for storing multiplexed digital video, audio, subtitles, and navigation menus. Although largely considered a legacy format replaced by modern containers like MP4, it remains a standard for physical media and often utilizes Content Scramble System technology for encryption and digital rights management.
