Method and apparatus for generating media-exchangeable multimedia data and method and apparatus for reconstructing media-exchangeable multimedia data

摘要

A method of generating multimedia data is provided. The method includes generating a scene tree by allocating at least one piece of object information to each of a plurality of nodes and then linking the nodes based on the relationship between a plurality of pieces of object information allocated to the nodes, adding a null node to which the object information of an exchangeable media object is allocated, and thereafter recording the null node in a scene descriptor area in a scene description language.
