About DVD VOB

VOB, encoded with MPEG-2, is a container format in DVD-Video. As one of the Video Manager and Video Title files under VIDEO_TS directory, VOB stores all the media content of a DVD, including digital video, digital audio, subtitles, DVD menus and navigation of a DVD. Another two information files are IFO and BUP respectively, the former of which contains video control and playback information while the latter is just the backup copy of IFO. Let's make it much clearer by checking a DVD-Video structure picture:
