Method and apparatus for constructing sensory effect media data file, method and apparatus for playing sensory effect media data file, and structure of the sensory effect media data file

摘要

Disclosed is a method and apparatus for constructing and playing a sensory effect media data file, which includes information on sensory effects. A method for constructing a sensory effect media data file according to an embodiment of the present invention includes: inserting first composition information, which represents a property of media data, into a composition information container field; inserting second composition information, which represents a property of sensory effect data, into the composition information container field; inserting a sample of the media data into a media data field, where the sample represents data associated with a timestamp; and inserting a sample of the sensory effect data into the media data field.
