Video is a consumer video format used to store digital video on
DVD discs, and as of 2003[update] was the dominant consumer video
format in Asia, North America, Europe, and Australia. Discs using
Video specification require a
DVD drive and an MPEG-2 decoder
(e. g., a
DVD player, or a computer
DVD drive with a software DVD
DVD movies are encoded using a combination MPEG-2
compressed video and audio of varying formats (often multi-channel
formats as described below). Typically, the data rate for
ranges from 3
Mbit/s to 9.5 Mbit/s, and the bit rate is
usually adaptive. It was first available on November 1, 1996 in Japan.
Video specification was created by
DVD Forum and can be
DVD Format/Logo Licensing Corporation for a fee of
$5,000. The specification is not publicly available and every
subscriber must sign a non-disclosure agreement. Certain information

To record moving pictures, DVD-
Video uses either H.262/MPEG-2 Part 2
compression at up to 9.8
Mbit/s (9,800 kbit/s) or MPEG-1
Part 2 compression at up to 1.856
Mbit/s (1,856 kbit/s).
Video supports video with a bit depth of 8-bits per color YCbCr
with 4:2:0 chroma subsampling.
The following formats are allowed for
H.262/MPEG-2 Part 2
H.262/MPEG-2 Part 2 video:
At a display rate of 25 frames per second, interlaced (commonly
used in regions with 50 Hz image scanning frequency):
720 × 576 pixels (same resolution as D-1)
704 × 576 pixels
352 × 576 pixels (same as the
China Video Disc
China Video Disc standard)
352 × 288 pixels
At a display rate of 29.97 frames per second, interlaced
(commonly used in regions with 60 Hz image scanning frequency):
720 × 480 pixels (same resolution as D-1).
704 × 480 pixels
352 × 480 pixels (same as the
China Video Disc
China Video Disc standard).
352 × 240 pixels
The following formats are allowed for MPEG-1 video:
352 × 288 pixels at 25 frame/s, progressive (Same as the VCD
352 × 240 pixels at 29.97 frame/s, progressive (Same as the VCD
Video with 4:3 frame aspect ratio is supported in all video modes.
Widescreen video is supported only in D-1 resolutions.
The MPEG-1 Part 2 format does not support interlaced video. The
H.262/MPEG-2 Part 2
H.262/MPEG-2 Part 2 format supports both interlaced and
progressive-scan content[clarification needed]. Content with a frame
rate different from one of the rates shown above can be encoded to
H.262/MPEG-2 Part 2
H.262/MPEG-2 Part 2 by using pulldown. This is most commonly used to
encode 23.976 frame/s content for playback at 29.97 frame/s. Pulldown
can be implemented directly while the disc is mastered, by actually
encoding the data on the disc at 29.97 frames/s; however this practice
is uncommon for most commercial film releases, which provide content
optimized for display on progressive scan television sets.
Alternately, the content can be encoded on the disc itself at one of
several alternate frame rates, and use flags that identify scanning
type, field order and field repeating pattern. Such flags can be added
in video stream by the
H.262/MPEG-2 Part 2
H.262/MPEG-2 Part 2 encoder. A
DVD player uses
these flags to convert progressive content into interlaced video in
real-time during playback, producing a signal suitable for interlaced
TV sets. These flags also allow reproducing progressive content at
their original, non-interlaced format when used with compatible DVD
players and progressive-scan television sets.
The audio data on a
DVD movie can be PCM, DTS, MPEG-1 Audio Layer II
Dolby Digital (AC-3) format. In countries using the PAL
system standard DVD-
Video releases must contain at least one audio
track using the PCM, MP2, or AC-3 format, and all standard
must support all three of these formats. A similar standard exists in
countries using the
NTSC system, though with no requirement mandating
the use of or support for the MP2 format. DTS audio is optional for
all players, as DTS was not part of the initial draft standard and was
added later; thus, many early players are unable to play DTS audio
tracks. Only PCM and DTS support 96 kHz sampling rate. Because
PCM, being uncompressed, requires a lot of bandwidth and DTS is not
universally supported by players, 96 kHz sampling rate is rare
for DVDs. The vast majority of commercial DVD-
Video releases today
employ AC-3 audio. The official allowed formats for
the audio tracks on a
PCM: 48 kHz or 96 kHz sampling rate, 16 bit or 24 bit Linear
PCM, 2 to 6 channels, up to 6,144 kbit/s; N. B. 16-bit
48 kHz 8 channel PCM is allowed by the DVD-
but is not well-supported by authoring applications or players;
AC-3: 48 kHz sampling rate, 1 to 5.1 (6) channels, up to 448
DTS: 48 kHz or 96 kHz sampling rate; channel layouts = 2.0,
2.1, 5.0, 5.1, 6.1; bitrates for 2.0 and 2.1 = 377.25 and 503.25
kbit/s, bitrates for 5.x and 6.1 = 754.5 and 1509.75 kbit/s;
MP2: 48 kHz sampling rate, 1 to 7.1 channels, up to 912 kbit/s.
DVDs can contain more than one channel of audio to go together with
the video content, supporting a maximum of eight simultaneous audio
tracks per video. This is most commonly used for different audio
formats – DTS 5.1, AC-3 2.0 etc. – as well as for
commentary and audio tracks in different languages.
Video discs have a raw bitrate of 11.08 Mbit/s, with a
Mbit/s overhead, leaving a payload bitrate of
10.08 Mbit/s. Of this, up to 3.36
Mbit/s can be used for
subtitles, a maximum of 10.08
Mbit/s can be split amongst audio and
video, and a maximum of 9.80
Mbit/s can be used for video alone.
In the case of multiple angles the data is stored interleaved, and so
there is a bitrate penalty leading to a max bitrate of 8
angle to compensate for additional seek time. This limit is not
cumulative, so each additional angle can still have up to 8
Professionally encoded videos average a bitrate of 4–5 Mbit/s
with a maximum of 7–8
Mbit/s in high-action scenes. Encoding at
less than the max bitrate (like this) is typically done to allow
greater compatibility among players, and to help prevent buffer
underruns in the case of dirty or scratched discs
Aiming to improve picture quality over standard editions, Columbia
TriStar Home Entertainment offered "Superbit" – a premium line
Video titles having average bitrates closer to 6 Mbit/s.
Audio quality was also improved by the mandatory inclusion of both
Dolby Digital and DTS 5.1 surround audio tracks. Multiple languages,
angles, and extra audio tracks were eliminated to free up more space
for the main title and thereby to ensure the highest data rate
possible. In January 2007 the
Superbit line was discontinued.
DVD hardware or software players may play discs whose MPEG files
do not conform to the above standards; commonly this is used to
support discs authored with formats such as VCD and SVCD. While VCD
and CVD video is supported by the
DVD standard, neither SVCD video nor
VCD, CVD, or SVCD audio is compatible with the
Some hardware players will also play DVD-ROMs or CD-ROMs containing
"raw" MPEG video files; these are "unauthored" and lack the file and
header structure that defines DVD-Video. Standard DVD-
contain extra information (such as the number of video tracks,
chapters and links to extra features) that
DVD players use to navigate
The maximum chapters allowed per title is 99 and the maximum titles
DVD is 99.
Almost all DVD-
Video discs use the UDF bridge format, which is a
combination of the
DVD MicroUDF (a subset of UDF 1.02) and ISO 9660
file systems. The UDF bridge format provides backwards
compatibility for operating systems that support only ISO 9660.
DVD players read the UDF filesystem from a DVD-
Video disc and
ignore the ISO9660 filesystem.
Directory and file structure
DVD volume for the DVD-
Video format has the following structure of
directories and files:
Layout of files for DVD-Video
AUDIO_TS directory: empty or not present on DVD-
Video discs; contains
files only on
DVD Audio discs; it is also known as an Audio Title Sets
directory; included on DVD-
Video discs for compatibility reasons
VIDEO_TS directory: stores all data for the DVD-Video; it is also
known as a
Video Title Sets directory. This directory is required to
be present on a DVD-compliant disc.
Video Manager (VMG) files:
IFO file: the
Video Manager (VMG) information file – stores
control and playback information for the entire
DVD – e. g. the
First Play PGC (Program Chain), locations of all
Video Title Sets
(VTS), table of titles, number of volumes, domains for multiple
languages and regional and parental control settings, information
about subtitles, audio tracks, etc. This file is required to be
present on a DVD-compliant disc.
VIDEO_TS.BUP file: the backup copy of the VIDEO_TS.
IFO file. It is
Video Manager (VMG).
VOB file: the first-play
Video Object of the DVD-
usually a copyright notice or a menu. It is part of
(VMG). This file is not required to be present on a DVD-compliant
Video Title Set (VTS) files:
IFO file: stores control and playback information for the
Video Title Set 01 – e. g. information about chapters,
subtitles and audio tracks. A "VTS_zz_0.IFO" file (where "zz" is from
01 to 99) is required to be present on each VTS.
VTS_01_0.BUP file: a backup copy of the VTS_01_0.
IFO file. This file
is required to be present on a DVD-compliant disc. It is part of Video
Title Set (VTS).
Video Title Set 01,
Video Object 0, contains the
menu for this title. This file is not required to be present on a
Video Title Set 01,
Video Object 1, contains the
video for this title. At least one file "VTS_zz_1.VOB" is required in
the VTS and each "VTS_zz_x". DVD-
Video can contain up to 99 (1–99)
titles with max 10 (0–9)
VOB files each. The last possible
IFO files store control and playback information – e. g.
information about chapters, subtitles and audio tracks. They do not
store any video or audio data or subtitles.
BUP files are only backups of the
Data structures recorded on a DVD-compliant disc are components of one
of the four data groups called domains:
First-play (FP) – First Play PGC located in the VIDEO_TS.
Video Manager (VMG) – contains VIDEO_TS.IFO, VIDEO_TS.BUP and
Video Title Set (VTS) – contains "VTS_zz_x.IFO", "VTS_zz_x.BUP" and
"VTS_zz_x.VOB" files (where "x" is from 1 to 9)
Video Title Set Menu (VTSM) – uses "VTS_zz_0.VOB" files
Main article: VOB
Video, audio, subtitle and navigation streams are multiplexed and
stored on a DVD-
Video disc in the
VOB container format (
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 AC-3,
DTS, LPCM or subtitles used in
VOB files) in the form of so-called
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
DVD recorders can use
DVD+VR format instead of DVD-Video.
DVD-VR format store multiplexed audiovisual content in VRO
containers. VRO file is an equivalent to a collection of
VOB files. Fragmented VRO files are not widely supported
by hardware or software players and video editing software. DVD+VR
standard defines a logical format for DVD-
Video compliant recording on
optical discs and is commonly used on DVD+R/RW media.
DVD-VR and DVD+VR
Video may also include up to 32 subtitle or subpicture tracks.
Subtitles are usually intended as a visual help for the deaf and
hearing impaired and for translating dialogs.
Subtitles can serve other purposes as well. For example, in the DVD
release of Thirteen Days one of the subtitle tracks includes history
notes, giving additional information timed to the events depicted in
the film. In the release of
For All Mankind
For All Mankind subtitles display names of
the NASA missions and names of the people shown on the screen. Shaun
of the Dead also features trivia facts about the making of the film on
its subtitles menu.
Subtitles are stored as bitmap images and therefore can contain
messages in any language. Subtitles are restricted to four colors,
including transparent "color", and thus tend to look cruder than
permanent subtitles on film. Transparency allows laying subtitles
over the video during playback. The subtitle tracks are contained
VOB file of the DVD.
Video may also contain closed captioning material which can only
be viewed on a television set with a decoder.
Chapters and angles
Video may contain chapters for easy navigation (and continuation
of a partially watched film). If space permits, it is also possible to
include several versions (called "angles") of certain scenes, though
today this feature is mostly used – if at all – not to
show different angles of the action, but as part of
internationalization to, for example, show different language versions
of images containing written text, if subtitles will not do
(e. g., the Queen's spell book in Snow White, and the scrolling
text in the openings of the
Star Wars films). Multiple angles have
found a niche in markets such as yoga, erotica and live performances.
A significant selling point of
Video is that the storage capacity
allows for a wide variety of extra, or bonus, features in addition to
the feature film. These extra features can include audio commentary;
documentary features, commonly about the making of the main title;
interviews; deleted footage; outtakes; photo galleries; storyboards;
isolated music scores; trivia text commentary; simple games; film
shorts; TV spots; radio spots; theatrical trailers which were used to
promote the main title; and teaser trailers advertising related movies
Extra features often provide entertainment or add depth and
understanding to the film. Games, bloopers, and galleries provide
entertainment. Deleted scenes and alternative endings allow the
audience to view additional content which was not included in a
theatrical release. Directors cuts allow the audience to see how the
director envisioned the main title without the constraints which are
placed on a theatrical release.
Other extras that can be included on DVDs are motion menus, still
pictures, up to 32 selectable subtitles, seamless branching for
multiple storylines, up to 9 camera angles, and
DVD-ROM / data files
that can be accessed on a computer.
Extra features require additional storage space, which often means
encoding the main title with lower than possible data rate to fit both
the main title and the extras on one disc. Lower data rate may
decrease visual and sound quality, which manifests itself in various
compression artifacts. To maintain quality the main title and the
extras may be released on several discs, or the extras may be omitted
completely like in the "Superbit" line of DVDs.
Video has four complementary systems designed to restrict the DVD
user in various ways: Macrovision,
Content Scramble System (CSS),
region codes, and disabled user operations (UOPs). There are also
anti-ripping techniques intended to foil ripping software.
Content Scramble System
Video titles use
Content Scramble System (CSS) encryption,
which is intended to discourage people from copying the disc. Usually,
users need to install software provided on the
DVD or downloaded from
the Internet such as MPlayer, TotalMedia Theatre, PowerDVD, VLC or
DVD to be able to view the disc in a computer system.
CSS does not make it difficult (any more) to copy the digital content
now that a decoder (DeCSS) has been released, nor is it possible to
distinguish between legal and illegal copies of a work, but CSS does
restrict the playback software that may be used.
CSS has caused major problems for the inclusion of
DVD players in any
open source operating systems, since open source player
implementations are not officially given access to the decryption keys
or license to the patents involved in CSS. Proprietary software
players were also difficult to find on some platforms. However, a
successful effort has been made to write a decoder by reverse
engineering, resulting in DeCSS. This has led to long-running legal
battles and the arrest of some of those involved in creating or
DeCSS code, through the use of the
Digital Millennium Copyright Act
Digital Millennium Copyright Act (DMCA), on the
grounds that such software could also be used to facilitate
unauthorized copying of the data on the discs. The
however, went on to make the libdvdcss library. Unlike DeCSS,
libdvdcss can access a CSS-encrypted
DVD without the need of a cracked
key, thus enabling playback of such discs on opensource players
without legal restraints (although
DVD rippers using this library may
still be subject to restrictions).
The DMCA currently affects only the United States, however many other
countries are signatories to the similar WIPO Treaty. In some
countries it is not illegal to use de-scrambling software to bypass
DVD restrictions. A number of software programs have since
appeared on the Web to view DVDs on a number of different platforms.
Other measures such as anti-ripping, as well as U.S. and non-U.S.
copyright law, may be used to prevent making unauthorized copies of
DVDs. CSS decrypting software, or ripping software, such as DVD
Decrypter, AnyDVD, MacTheRipper, and
DVD Shrink allows a disc to be
copied to hard disk unscrambled. Some
DeCSS applications also remove
Macrovision, region codes, and disabled user operations (UOPs).
DeCSS ripping software became available, companies developed
techniques to introduce errors in DVD-
Video discs that do not normally
affect playback and navigation of a disc, but can cause problems in
software that attempts to copy the entire disc. These approaches,
which are not part of the official DVD-
Video specification, include
Sony ARccOS Protection,
Macrovision RipGuard, X-protect, ProtectDisc
SecureBurn, Anaho, Fortium, and others. All of these methods have
been circumvented (as might have been expected, since all standard DVD
players naturally circumvent them to play and navigate the discs
Riplock is a feature that reduces drive noise during
playback but inadvertently reduces ripping speed.
Disabled user operations
Main article: User operation prohibition
Video allows the disc to specify whether or not the user may
perform any operation, such as selecting a menu, skipping chapters,
forwarding or rewinding – essentially any function on the
remote control. This is known as User Operation Prohibitions, or
Prohibited User Operations (UOPs or PUOs). Most
DVD players respect
these commands (e. g., by preventing skipping or fast-forwarding
through a copyright message or an advertisement at the beginning of a
disc). However, grey market players ignore UOPs and some DVD
"re-authoring" software packages allow the user to produce a copy
without these restrictions. The legality of these activities varies by
jurisdiction and is the subject of debate. (See fair use.)
DVD region code
DVD region codes across the world
Video disc contains one or more region codes, denoting the
area(s) of the world in which distribution and playback are intended.
DVD player specification dictates that a player must
only play discs that contain its region code. In theory, this allows
the motion picture studios to control the various aspects of a release
(including content, date and price) on a region-by-region basis, or
ensure the success of "staggered" or delayed cinema releases from
country to country. For example, the British movie
28 Days Later
28 Days Later was
Europe several months prior to the film's release
in North American movie theaters. Regional coding kept the European
DVD unplayable for most North American consumers, thereby ensuring
that ticket sales would be relatively unaffected.
In practice, many
DVD players allow playback of any disc, or can be
modified to do so. Entirely independent of encryption, region coding
pertains to regional lockout, which originated in the video game
From a worldwide perspective regional coding may be seen as a
failure. A huge percentage of players outside of
North America can
be easily modified (and are even sold pre-modified by mainstream
stores such as Amazon.co.uk) to ignore the regional codes on a disc.
This, coupled with the fact that almost all televisions in
Australasia are capable of displaying
NTSC video (at the very least,
in black and white), means that consumers in these regions have a huge
choice of discs. Contrary to popular belief, this practice is not
illegal and in some countries that strongly support free trade it is
DVD player can only play region-coded discs designated for
the player's own particular region. However, a code-free or
DVD player is capable of playing DVDs from any of the six
regions around the world.
The CSS license prohibits manufacturing of
DVD players that are not
set to a single region by default. While the same license prohibits
manufacturers from including prominent interfaces to change the region
setting it does not clearly prevent them from including "hidden" menus
that enable the player's region to be changed; as such, many high-end
models in the U.S. include password-protected or otherwise hidden
methods to enable multi-region playback. Conversely in the UK and
Ireland many cheap
DVD players are multi-region while more expensive
systems, including the majority of home cinema systems, are preset to
play only region 2 discs.
In China, DVD-Videos for television series are usually released in
MPEG-1 video, with MP2 audio. By forgoing Dolby standards,
manufacturers cut costs considerably; encoding in lower bit-rates also
allows a TV series to be squeezed onto fewer discs. There is no region
coding in such cases.
There are also two additional region codes, region 7, which is
reserved, and region 8, which is used exclusively for passenger
transport such as airlines and cruise ships.
A virtual machine implemented by the
DVD player runs bytecode
contained on the DVD. This is used to control playback and display
special effects on the menus. The instruction set is called the
Virtual Machine (VM)
DVD command set. There are 16 general parameter
registers (GPRM) to hold temporary values and 24 system parameters
(SPRM). As a result of a moderately flexible programming interface,
DVD players can be used to play games, such as the
DVD re-release of
Dragon's Lair, along with more sophisticated and advanced games such
as Scene It, all of which can be run on standard
Players and recorders
DVD player and
DVD recorders often support additional formats, including
DVD+/-R/RW, CD-R/RW, MP3, WMA, SVCD, JPEG, PNG, SVG, KAR and MPEG-4
(DivX/Xvid). Some also include USB ports or flash memory readers.
Player prices range from as low as US$ 20 (GB£ 10)[citation
needed] to as high as US$2,700 (GB£1,350).
DVD drives for computers usually come with one of two kinds of
Regional Playback Control (RPC), either RPC-1 or RPC-2. This is used
to enforce the publisher's restrictions on what regions of the world
DVD can be played. (See
Regional lockout and
DVD region codes.)
Open source software
DVD players allow everything, commercial
ones (both standalone models and software players) come further
encumbered with restrictions forbidding the viewer from skipping (or
in some cases fast-forwarding) certain content such as copyright
warnings or advertisements. (See User operation prohibition.)
Video game systems with DVD-
Video playback functionality include:
Panasonic Q, PlayStation 2, PlayStation 3, PlayStation 4,
Wii (with an
unsupported hack), Xbox (additional remote required), Xbox 360,
and Xbox One.
Competitors and successors
In April 2000, Sonic Solutions and Ravisent announced hDVD, a
high-definition extension to DVD. However h
DVD failed to gain much
On November 18, 2003, the Chinese news agency Xinhua reported the
final standard of the Chinese government-sponsored Enhanced Versatile
Disc (EVD) which is another extension of standard DVD. Shortly
thereafter the development of the format was halted by a licensing
dispute between Chinese companies and On2 Technologies, but on
December 6, 2006, 20 Chinese electronic firms unveiled 54 prototype
EVD players and announced their intention for the format to completely
replace DVDs in China by 2008. However, due to a lack of sales,
support for EVD has recently[when?] been dropped by the Xinhua
Bookstore in Wuhan, which was a major supporter of the format.
Blu-ray Disc and HD DVD
See also: High definition optical disc format war
Two competing high-definition (HD) optical-disc formats, HD
Blu-ray, were introduced in 2006. The HD
DVD format, promoted by
Toshiba, had the backing by the
DVD Forum, which voted to make it the
official successor to DVD. Opposing HD
DVD was the
Blu-ray format, led
Blu-ray Disc Association, which shares many members with the
DVD launched in March 2006 and
Blu-ray launched in June of the
same year, a format war started. Industry analysts likened the
situation to the VHS/
Betamax format war of the 1980s. At the time of
their launch, consumer awareness of either high-definition format was
severely limited, with the end result that most consumers avoided both
formats, already content with DVD. In February 2008, Toshiba
capitulated, citing low demand for HD
DVD and the faster growth of
Blu-ray, and the inclusion of the format in the video game system
PlayStation 3 (PS3), among other reasons. Toshiba ended production
of their HD
DVD players and discontinued promotion of the format,
while the HD
DVD movie release schedule concluded by June 2008.
DVD was discontinued,
Blu-ray became the de facto
high-definition optical disc format. However, sales figures suggest
DVD is in no immediate danger of disappearing. All standard DVDs
will play on existing
Blu-ray players, making the switch to Blu-ray
much easier than the switch from
VHS to DVD. Moreover, some labels are
cutting back on
Blu-ray Disc releases in favor of DVD-Video, claiming
that low sales do not justify the more expensive
format. In addition, a growing number of hardware vendors are
Blu-ray players with Internet connectivity for
subscription-based video downloads.
