CSS stands for Content Scrambling System.
In DVD-Video, an encryption scheme designed to protect copyrighted material that resides on a disc by periodically scrambling the data using encryption keys. A tool named Decss can allow users to circumvent it.
DVD-ビデオ、定期的に暗号鍵を使用してデータをスクランブルして、ディスク上に存在する著作物を保護するように設計された暗号方式である。 DeCSSのという名前のツールは、ユーザーがそれを回避できるようにすることができます。
Although Decss didn't exactly crack the CSS, but instead used leaked decryption keys.

On a DVD disc, DVD movie 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.
If you look at the files on a DVD, you will notice that most DVDs have both a VIDEO_TS and AUDIO_TS folder, but the AUDIO_TS folder is usually empty. DVD-Audio would be stored in an AUDIO_TS folder but is a separate format to DVD-Video.
VOB stands for DVD Video OBject.
The VOB file is one of the core files found on DVD-Video discs and contains multiplexed Dolby Digital audio (normally AC3 format) and MPEG-2 video.
VOB files on a DVD are numbered as follows: vts_XX_y.vob where XX represents the title and Y the part of the title.
There can be 99 titles and 10 parts, although vts_XX_0.vob does not contain any video, usually just menu or navigational information. You can find them on a DVD video disc in a subdirectory labelled VIDEO_TS. View VOB to MPEG Converter
ISO refers also to a CD or DVD image (not picture..) file with an extension of ".iso".
The extension comes from the full name of the CD-ROM and DVD-ROM filesystem specification, ISO 9660.
拡張機能は、CD-ROMやDVD-ROMのファイルシステムの仕様、ISO 9660のフルネームから来る。
Just like other CD/DVD image formats, ISO is a file that contains full content of the disc, including every single track,directory, file and information about the structure of the disc.
ただ、他のCD/ DVDイメージ形式のように、ISOはすべてのシングルトラック、ディレクトリ、ファイル、ディスクの構造に関する情報を含む、ディスクの完全な内容を含むファイルです。
Normally ISO files are being used to replicate existing CD/DVD discs, transfer those discs over the network to other location (or to other person) and burn back to CD/DVD which then would be an identical replica of the original disc.
通常のISOファイルは、既存のCD/ DVDディスクを複製、他の場所(または他の人に)ネットワークを介して、それらのディスクを転送し、CD / DVDた後、元のディスクの同一のレプリカだろうに戻って焼くために使用されている。
VCD stands for Video Compact Disc.
VCD is a standard developed in early 1990's that allows regular CD to contain 74 minutes of video and audio.
Both, video and audio, are encoded in MPEG1format and stored on the CD in specific format. A VCD can be played on almost all standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM driver with the help of a software based decoder/player.
VCD is a very popular method for movie distribution in China, Singapore, Malaysia, etc.. Some studios release some of their movies officially for VCD format in Asia . It has almost completely replaced regular VHS format in Asia, because cheap VCD recorders are widely available there. VCD's successor is called SVCD.
VCDは、中国、シンガポール、マレーシアなどでの映画配給のための非常に人気のある方法です。一部のスタジオでは、正式にアジアでVCD形式のための彼らの映画の一部を解放します。安いVCDレコーダーが広く入手可能であるので、それはほぼ完全に、アジアでの正規VHSフォーマットを置き換えています。 VCDの後継者は、SVCDと呼ばれ
SVCD stands for Super Video Compact Disc (called also SuperVCD or Chaoji VCD).
SVCD(またSuperVCDまたはChaoji VCDと呼ばれる)スーパービデオコンパクトディスクの略です。
SVCD is a new CD standard developed in 1998 by Chinese consumer electronics manufacturers, Chinese government and VCD consortium (Sony, Philips, Matsushita and JVC) that allows regular CD to contain 35-60 minutes of video and audio.
A SVCD is very similiar to a VCD, although SVCD's video bitrate is normally higher than VCD's.
SVCD contains very good quality full-motion MPEG2 video along with up to 2 stereo audio tracks (MPEG1 stereo audio layer II, MPEG2 stereo audio layer II or MPEG2 Multi-Channel 5.1 surround audio) and also 4 selectable subtitles.
A SVCD can be played on many standalone DVD Players and of course on all computers with a DVD-ROM or CD-ROM driver with the help of a software based decoder/player.
Just like VCDs (and audio CDs), SVCDs require a specific way how they are burned on the CD -- just sticking all the required files into CD structure doesn't make disc a SVCD compatible.
ただ、VCDの(やオーディオCD)のように、SVCDのは、それらがCDに焼かれているどのように特定の方法を必要とする - ちょうど必要なすべてのファイルをCD構造にを貼りませんディスクSVCD互換性を持たせる。
Most of the new CD burning applications support SVCD already, so authoring your own SVCDs should be relatively easy.
XVCD stands for eXtended VCD.
XVCD has same features as VCD but it is possible to use higher resolution and higher bitrates to get higher video quality.
XVCD burned in "VCD" Mode on a CD-R or CD-RW can be played on some hardware VCD or DVD players and many computers with appropriate software.
CD-RまたはCD-RWの "VCD"モードで焼かXVCDは、適切なソフトウェアを使用していくつかのハードウェアのVCDやDVDプレーヤーや多くのコンピュータで再生することができます。
XSVCD stands for eXtended SVCD.
XSVCD has same features as SVCD but it is possible to use higher resolution and higher bitrates to get higher video quality.
XSVCD burned in "SVCD" Mode on a CD-R or CD-RW can be played on some hardware DVD players and many computers with appropriate software like a software DVD player or a media player with a MPEG-2 codec.
CD-RまたはCD-RWの "SVCD"モードで焼かXSVCDは、ソフトウェアDVDプレーヤーやMPEG-2コーデックとメディアプレーヤーのような適切なソフトウェアを使用していくつかのハードウェアのDVDプレーヤーや多くのコンピュータで再生することができます。
VHS stands for Vertical Helix Scan.
VHS is the video casette format and technology introduced by JVC in 1976. It is an analog format capable of delivering 240 lines of video resolution, along with stereo sound that's nearly as good as CD.
Blank tapes usually feature either 120 minutes or 160 minutes of recording time at the highest recording speed (6 hours or 8 hours at the slowest speed).
In the Internet piracy scene, this term means a release of a movie, or some form of video, that has been taken from a VHS source.
It has been captured and then re-encoded to a digital format. Some groups are dedicated to releasing VCD copies of movies that haven't been released on DVD as of yet.
SVHS stands for SuperVHS.
SVHS is an improved, high-resolution VHS standard developed by JVC to offer better video quality than the VHS format.
SVHS recording can't be played back correctly with VHS videos, unless VHS VCR has something called "super quality playback" that allows playing SVHS tapes.
DVHS is a digital recording and playback format for High Definition material. It's based on the existing 1/2" VHS-sized cassettes.
DVHSは、高品位材料のためのデジタル録音·再生フォーマットです。それは、既存の1/2 "VHSサイズのカセットに基づいている。
NTSC stands for National Television System Committee.
NTSC is a color TV standard developed in the United States in 1953 by National Television System Committee. NTSC is used in most of the American continent countries and in various Asian countries. Rest of the world uses either some variety of PAL or SECAM standards.
NTSCは、ナショナルテレビジョンシステム委員会が1953年に米国で開発されたカラーテレビの標準です。 NTSCはアメリカの大陸のほとんどの国で、様々なアジアの国々で使用されています。世界の残りの部分は、PALまたはSECAM規格のいずれかのいくつかのさまざまなを使用しています。
NTSC runs on 525 lines/frame and it's vertical frequency is 60Hz. NTSC's framerate is 29.97 frames/sec.
NTSCは525ライン/フレーム上で動作し、それの垂直周波数が60Hzのである。 NTSCのフレームレートは29.97フレーム/秒です。
PAL, was introduced in the early 1960's in Europe, stands for Phase Alternating Line.
It has better resolution than in NTSC, having 625 lines/frame, but the framerate is slightly lower, being 25 frames/sec.
PAL is used in most of the western European countries (except France, where SECAM is used instead), Australia, some countries of Africa, some countries of South America and in some Asian countries.
ASX stands for Advanced Stream Redirector.
An asx file is used to store information on servers and media files for streaming video and audio over the Internet, such as multimedia web sites. The .asx file is a simple text file that contains server and media information, so you can easily find out the name of the file and server address of the streaming content with a text editor.
ASXファイルは、マルチメディアウェブサイト、インターネット経由でストリーミングビデオ及びオーディオ用のサーバおよびメディアファイルに関する情報を格納するために使用される。 。ASXファイルは、サーバーとメディア情報を含む単純なテキストファイルですので、簡単にテキストエディタを使用してストリーミングコンテンツのファイルおよびサーバー·アドレスの名前を見つけることができます。
Codec stands for Coder/Decoder.
Basically it is a piece of software or a driver that adds a support for certain video/audio format for your operating system. With codec, your system recognizes the format the codec is built for and allows you to play the audio/video file (=decode) or in some cases, to change another audio/video file into that format (=(en)code).
DRM stands for Digital Rights Management.
DRM doesn't mean just basic copy-protection of digital content (like ebooks, MP3s or DivX videos), but it basically means full protection for digital content, ranging from delivery to end user's ways to use the content.
somehow DRM system needs to know when the copying is allowed and when not -- users also have rights to make copies to their closest relatives, etc. So, normally this has been solved by allowing "hops" -- original file can be copied, but the copy of the original file cannot be copied any further.
何とかDRMシステムは、コピーが許可されているかを知る必要があるとしていないとき - ユーザーは、通常は、これは"ホップ"を可能にすることによって解決されている、だから彼らの最も近い親戚にコピーを作成する権限などを持っている - 元のファイルをコピーすることができ、しかし、元のファイルのコピーがそれ以上コピーすることはできません。
Obviously this also causes problems, if user accidentally deletes the original file, but still has the legal copy of the file.
Region codes in this instance mean flags implemented in DVD-Video discs that determine the geographic area where the DVD-Video disc is being sold and where it can be watched. These codes ensure that one country doesn't get a DVD movie before the same movie is out in that country's theatres. In their corporate omniscience, movie
studios have carved the planet into regions with each region having a specific code.
All DVD players and discs have region codes.
A DVD player and disc must be of the same region or the disc will not play.
If you want to watch movies from other countries, you need a multiregion DVD player.
This will allow you to play any disc from any region.
The region controls are also implemented in PC's DVD-ROM drivers, normally in three levels.
First of all, if the DVD-ROM driver is manufactured after 1st of January, 2000, the driver itself has physical locks implemented in it to permit playback of only specific region code. Secondly, all newer operating systems, including Windows 2000 and Windows XP, have region control measurements built-in. And finally, the DVD player software, such as WinDVD or PowerDVD, have region control measurements built-in.
DVD-ROMドライバが2000年1月1日以降に製造されている場合、すべての最初、ドライバ自体は、特定の地域コードの再生を可能にすることで実装されている物理ロックを有する。第二に、Windows 2000およびWindows XPを含むすべての新しいオペレーティングシステムでは、内蔵の領域制御測定値を持っている。そして最後に、このようなWinDVDのか、PowerDVDのようなDVDプレーヤーのソフトウェアは、内蔵の領域制御測定値を持っている。
Streaming format can send live or on-demand video or audio broadcast over the Internet. Popular streaming video formats include RealVideo, QuickTime (MOV) and WMV.
