Abstract
The present invention relates to a multimedia data encoding/decoding method and apparatus. The encoding method includes generating a data area comprising a plurality of media data areas; generating a plurality of track areas corresponding to the plurality of media data areas, respectively; and generating a meta area comprising a first area comprising identification information on media data and a second area comprising position information on the media data. 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.
Claims27
An encoding method comprising:
