Abstract
Provided are a method and apparatus for generating and accessing metadata in a media file format. The method of generating metadata in a media file format includes generating a time-track map composed of a plurality of map nodes that are distinguished according to track and unit time, and generating media objects corresponding to each of the map nodes, in which each of the map nodes includes position information of the corresponding media objects, thereby facilitating real-time reproduction and modification of content.
