Embedding MPEG-7 Metadata Within a Media File Format



Wo L. Chang


Embedding metadata within a media file format becomes evermore popular for digital media. Traditional digital media files such as MP3 songs and JPEG photos do not carry any metadata structures to describe the media content until these file formats got extended with ID3 and EXIF. Recently both ID3 and EXIF advanced to version 2.4 and version 2.2 respectively with much added new description tags. Currently, most MP3 players and digital cameras support the latest revisions of these metadata structures as the de- facto standard formats. Given the benefits of having metadata to describe the media content is very critical to consumers for viewing and searching media content. However, both ID3 and EXIF were designed with very different approaches in terms of syntax, semantic, and data structures. Therefore, these two metadata file formats are not compatible and cannot be utilized for other common applications such as slideshow for playing MP3 music in the background and shuffle through images in the foreground. This paper presents the idea of embedding the international standard of ISO/IEC MPEG-7 metadata descriptions inside the rich ISO/IEC MPEG-4 file format container so that a general metadata framework can be used for images, audio, and video applications.
