What is VOB?
VOB is the extension of the files contained in DVD-Video media. All DVD
movies are stored in VOB files on DVDs. VOB file contains video, audio,
subtitle and menu in stream form. On the DVD, all the content for one title
set is contiguous, but broken up into 1 GiB VOB files in the computer compatible
file systems for the convenience of the various operating systems. Images,
video and audio used in DVD menus are stored in VOB files. Basically VOB
file is just a basic MPEG-2 system stream -- meaning that it is a file
that contains multiplexed MPEG-2 video stream, audio streams (normally
AC3 and DTS formats) and subtitle streams. Since VOB files contain an MPEG-2
video codec, they can be opened and streamed individually with a media
player. IFO (information) files contain all the information a DVD player
needs to know about a DVD so that the user can navigate and play all DVD
content properly, such as where a chapter starts, where a certain audio
or subtitle stream is located, information about menu functions and navigation.
Authentication of the disc allows the copying of individual VOB files without
error, but the encryption keys will not be copied. If the copied undecrypted
VOB files are opened in a player, they will request the keys from the DVD-ROM
drive and will fail. Windows Media Player, VLC and Media Player Classic
are all free applications that support playback for these files. These
apps make it possible to view a disc's contents without loading it into
a DVD player, and resemble each other closely in terms of media management.
MPlayer, VLC media player, GOM player, Media Player Classic and more platform-specific
players like ALLPlayer play VOB files.
What is 3GP?
3GP is container formats similar to MPEG-4 Part 14 (MP4), which is also
based on MPEG-4 Part 12. Some cell phones use the .mp4 extension for 3GP
video. The Macintosh type is: 3GPP. The 3GP file format was designed to
decrease storage and bandwidth requirements in order to accommodate mobile
phones. 3GPP allowed use of AMR and H.263 codecs in the ISO base media
file format (MPEG-4 Part 12), because 3GPP specified the usage of the Sample
Entry and template fields in the ISO base media file format as well as
defining new boxes to which codecs refer. It also contains descriptions
of image sizes and bitrate. The MP4 and the AVC file format specifications
described usage of MPEG-4 content in the ISO base media file format. 3GPP
is the new worldwide standards for the creation, delivery and playback
of multimedia over 3rd generation, high-speed wireless networks. The 3GP
file type is primarily associated with '3GPP'. 3GPP is based on the MPEG-4
standard which was derived from Apple's QuickTime. The 3GP is used on 3G
mobile phones but can also be played on some 2G and 4G phones. It stores
video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264),
and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC or HE-AAC. For the
storage of MPEG-4 media specific information in 3GP files, the 3GP specification
refers to MP4 and the AVC file format, which are also based on the ISO
base media file format. 3GPP file format was designed for GSM-based Phones
and may have the filename extension ".3gp". Some newer/higher-end
phones without 3G capabilities may also playback and record in this format
(again, with said limitations).
