Ogg Vorbis will be described in more detail to help understand the concept according to the present invention.

Ogg Vorbis is a new kind of digital music format created against the charge of MP3. A series of volunteers, starting with Christopher Montgomery, a student at MIT University in 1998, who announced that Fraunhofer Institute will charge MP3, began researching a new music format to replace MP3. The goal of the new music format is: higher compression rates than MP3, better sound quality than MP3, and unlimited use, distribution, and development in open source formats.

The best representation of the Ogg Vorbis feature is that there is no restriction on the use of the format itself. Ogg Vorbis encoders and decoders require no royalties or licenses to author, distribute, or use. Development tools are also available, allowing users to modify and supplement their own code if desired.

Currently, anyone can download a free trial version of Ogg Vorbis via the web page (www.vorbis.com). Since only the prerelease "RC3" has been developed, there is a lack of file encoding time and stability. But Ogg Vorbis can create music files on music CDs just like MP3s, and can also listen to music through existing MP3 playback programs like WinAmp. In addition, the sound quality is better than that of MP3, but on average 38% less hard disk drive (HDD) capacity than MP3 files.

The biggest distinction between Ogg Vorbis files and traditional music files is that they support Variable Bit Rate (VBR) by default. Of course, MP3 also supports VBR format, but since it is VBR based on existing MP3, it is effective only in capacity reduction. The Ogg Vorbis file, on the other hand, supports VBR by default, and its bit rate width has been improved to 500 Kbps in the recently announced RC3, so you can enjoy high quality music without loss. Also, from the latest version, you can set various sound quality through an option called 'Quality'.
