Abstract

The present invention relates to a multimedia data encoding/decoding method and apparatus. The encoding method includes generating a data area including a plurality of media data areas; generating a media information area including a plurality of track areas corresponding to the plurality of media data areas, respectively; and generating an animation area having information on an animation effect to be applied to media data included in the media data area. According to the present invention, the multimedia data encoding/decoding method and apparatus has an effect of being capable of constructing a slide show by only a small amount of multimedia data. Thus, a time taken to process and transmit the multimedia data can reduce.
