What is VOB

About VOB Format

VOB is short for Video Object, a container format in DVD-Video media. VOB can contain video, audio, subtitle and menu contents multiplexed together into a stream form. VOB is based on the MPEG program stream format, but with additional limitations and specifications in the private streams. The MPEG program stream has provisions for non-standard data (as used in VOB files) in the form of so-called private streams. VOB files are a very strict subset of the MPEG program stream standard. While all VOB files are MPEG program streams, not all MPEG program streams comply with the definition for a VOB file.

VOB files can be played by almost any conventional video player. They can be played on Macintosh using Apple DVD player, MPlayer, and VLC Media Player; on Linux using Xine, MPlayer, and VLC Media Player; and on Windows using CyberLink Power DVD, Media Player Classic (MPC), VLC Media Player, and Nero Showtime.

DVD VOB file and IFO file – the difference is as follows:

IFO normally refers to a file on DVD-Video disc and stands for InFOrmation.While the main content of DVD-Video disc are the VOB files which contain the actual MPEG-2 audio, video and subtitle streams, the IFO files provide information for DVD player where DVD-Video disc’s chapters start, where certain audio tracks are located, etc..

DVD VOB file and VIDEO_TS folder – the difference is as follows:

On a DVD disc, VOB files are stored in the VIDEO_TS folder. There is also an AUDIO_TS folder, this is where DVD-Audio would be stored, but usually the folder is empty. The TS stands for “title set” and is part of DVD structure. The before mentioned VIDEO_TS folder will hold all the pertinent information such as Informaton (IFO) and any backup (BUP) files that are necessary for the DVD to even be read.
