Ogg

The Ogg file format has been designed by Xiphophorous? as a free and open alternative to multimedia formats such as QuickTime and [Windows Media]?. As of November 2001, implementations support only the Vorbis lossy audio codec, but developers continue to work on other codecs.

• Vorbis: perceptual lossy audio compression that has already surpassed MP3 in quality bit-for-bit
• Tarkin?: lossy video compression
• MNG: animation based on PNG and JPEG. Ogg MNG can potentially replace the various incompatible [motion JPEG]? systems in existence.
• XML: text, good for subtitles and captions
