Ogg is a file format, which can contain audio, video as well as text datas. It is thereby a Multimedia container. Ogg was conceived with the goal of storing Multimedia contents efficiently and of streamen at the same time of having and a free and alternative unrestricted of software patents to prop. guessing eras formats. The development of the container is led of the Xiph.Org Foundation, which is responsible for some codecs, which compress contents in a Ogg container.
The most well-known codec is thereby the audio codec Vorbis, with which Ogg is frequently falsely confounded or seen as unit, although Ogg of the containers for Vorbis coded contents is. The container format Ogg is used also with different Wiki projects like the Wikiprojekt spoken Wikipedia.
For technical aid for playing Ogg formats see Wikipedia: Audio.
The development of the container format began 1993 under the name "Squish", which hurt however trademark laws. Therefore the name was replaced by an expression from the computer game Netrek, which meant as much as tons ogg: "ton of DO anything forcefully, possibly without consideration OF the drain on future resources "(about: "somewhat very energetically concern, possibly also without consideration for the negative effects "). With the name one of the main characters of the disk world novels, the witch Nanny Ogg, had this naming according to the Xiph.Org Foundation however nothing to do What's in A on the web page of the Xiph.Org Foundation, 2004.
In the autumn 1998 Christopher Montgomery began with the development of the audio codec Vorbis, after the institute for Fraunhofer began to implement royalties for its popular MP3-Format. By the increasing spreading of Vorbis the container format Ogg experienced an upswing.
On 12 July 2002 Ogg in the version 1.0 was released, those as the first stable version also for final users meant was Nico Jurran: Free audio format Ogg Vorbis shines golden on Heise on-line, 12 July 2002.
In May 2003 the definition followed by RFCs: RFC 3533 defines the encasing data stream, while RFC 3534 defines the type of MIME medium of Ogg files, application/ogg. Rarely the still used type of medium application/x ogg however originates from earlier time, than the official type was not yet specified.
The current version of the Ogg Containerformats is the version of 1.1.3 Web servers of the Xiph.Org Foundation, 19 January 2006.
The Ogg Containerformat is a Bitstream format. It groups and codes thereby the packages into sequential sides of a structured Bitstreams. These as logical Bitstreams marked rivers are coded thereby only in each case with a codec. However several logical Bitstreams can be in a container. Several video Bitstreams can also e.g. be contained, which may overlay also temporally. This logical Bitstreams is then transferred for storage or the actual Streamen to another equipment or program into a physical Bitstream, from which the decoder sets the individual logical Streams again together.
The codecs used in the logical Bitstreams are the audio, video and text codecs of the Xiph.Org Foundation. The most important codecs are thereby the audio codecs Vorbis and FLAC, like that as the video codec Theora and the language data codec Speex.
Ogg was established in the IT-industry meanwhile as a standard. First of all within the audio range Ogg in connection with the audio codec Vorbis of a set of software is supported like also hardware products (see also the article Vorbis). In the video range the spreading of Ogg is still moderate in connection with Theora, since the development is not finally considered as yet (see also the article Theora). He enjoys however in the free software scene of increasing popularity.
The designation Ogg was registered in the year 2001 as mark. A company with seat in London could use this mark according to own data medium-term for warnings, i.e. who uses the designation Ogg then without valid license e.g. on homepage, the risk would run, by warning to high cash payments to be requested. According to an Telepolis article a such business purpose offends however meanwhile against German right wolf Dieter Roth: Is "Ogg" soon no more open in Telepolis, 02 October 2005.
