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. 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. VOB file cannot contain AAC audio (MPEG-2 Part 7), MPEG-4 compression
formats and others, which are allowed in MPEG program stream standard.
A player of generic MPEG-2 files can usually play unencrypted VOB files,
which contain MPEG-1 Audio Layer II audio. Other audio compression formats
such as AC-3 or DTS are less widely supported. The VOB format is based
on the MPEG program stream format, but with additional limitations and
specifications in the private streams. Digital Versatile Discs, more commonly
called DVDs, use the VOB file format for storing the audio and video content
within the same file. VOB files typically are quite large and cannot be
played once removed from a DVD. 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. Many DVD-Video
titles are encrypted with Content Scramble System (CSS). This is a data
encryption and communications authentication method designed to prevent
copying video and audio data directly from the DVD-Video discs. Decryption
and authentication keys needed for playing back encrypted VOB files are
stored in the normally inaccessible lead-in area of the DVD and are used
only by CSS decryption software (e.g., in a DVD player or software player).
What is WebM?
The WEBM container format is based on the Matroska container, which stores
Matroska video in .MKV files. Most major Web browsers will support WebM
as part of HTML5 video delivery. Google acquired ON2, the original developer
of VP8 technology. VP8 is now an open and free technology. VP8 is a highly
efficient video compression technology that was developed by On2 Technologies.
Google acquired On2 in February, 2010. For more information, see the -VP8
Video Codec" section below. In mid-2010, Simon Phipps, a board member
for the Open Source Initiative, expressed doubts as to whether the original
WebM license was an open-source license, since it had not been submitted
to the OSI for approval. The team that created VP8 have been pioneers in
video codec development for over a decade. VP8 delivers high quality video
while efficiently adapting to the varying processing and bandwidth conditions
found on today's broad range of web-connected devices. Also ST-Ericsson
and Huawei have hardware implementations in their computer chips. A WebM
file consists of VP8 video and Vorbis audio streams, in a container based
on a profile of Matroska. Skype has implemented the VP8 codec into the
Skype 5.0 software. In January 2011, Google announced that the WebM Project
Team will release plugins for Internet Explorer and Safari to allow playback
of WebM files through the standard HTML5 <video> tag. As of 9 June
2012, a public preview version of this plug-in is available for Internet
Explorer 9. VP8's efficient bandwidth usage will mean lower serving costs
for content publishers and high quality video for end-users. The codec's
relative simplicity makes it easy to integrate into existing environments
and requires less manual tuning to produce high quality results. These
existing attributes and the rapid innovation we expect through the open-development
process make VP8 well suited for the unique requirements of video on the
web.
