The Matroska Multimedia Container is an open standard free container format, a file format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file.〔(Matroska Format Specifications ), Matroska.org.〕 It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF), but is entirely open in specification, with implementations consisting mostly of open source software. Matroska file extensions are .MKV for video (with subtitles and audio), .MK3D for stereoscopic video, .MKA for audio-only files, and .MKS for subtitles only.〔See FAQ. "What file extensions does Matroska use?" http://www.matroska.org/technical/guides/faq/index.html〕 "Matroska" is derived from ''Matryoshka'' ((ロシア語:матрёшка) (:mɐˈtrʲɵʂkə)), which refers to the hollow, wooden, "Russian doll", or ''Matryoshka doll'', that opens to expose another doll that in turn opens to expose another doll, and so on. The logo uses "Matroška", with the caron over the "s", as the letter š represents the "sh" sound (as in "Matryoshka") in the Slavic languages in which it is used. == History == The project was announced on 6 December 2002〔(【引用サイトリンク】url=http://www.matroska.org/news/archives2.html )〕 as a fork of the Multimedia Container Format (MCF), after disagreements between MCF lead developer Lasse Kärkkäinen and soon-to-be Matroska founder Steve Lhomme about the use of the Extensible Binary Meta Language (EBML) instead of a binary format. This coincided with a long coding break by the MCF's lead developer, during which most of the community quickly migrated to the new project. In 2010, it was announced that the WebM audio/video format would be based on a profile of the Matroska container format together with VP8 video and Vorbis audio.〔(''Frequently Asked Questions'' ), the WebM project〕 On October 31, 2014, Microsoft confirmed that Windows 10 will support HEVC and Matroska out of the box, according to a statement from Gabriel Aul, the leader of Microsoft Operating Systems Group's Data and Fundamentals Team. Windows 10 Technical Preview Build 9860 added platform level support for HEVC and Matroska. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Matroska」の詳細全文を読む スポンサード リンク
