SENSORY EFFECT EXPRESSION METHOD AND APPARATUS THEREFOR, AND COMPUTER-READABLE RECORDING MEDIUM WHEREON SENSORY DEVICE COMMAND METADATA ARE RECORDED

摘要

The present invention deals with a sensory effect expression method and apparatus therefor, and a computer-readable recording medium whereon sensory device command metadata are recorded. The sensory effect expression method of the present invention comprises a step wherein sensory effect metadata including sensory effect information are received as input, a step wherein the sensory effect metadata are analyzed to acquire said sensory effect information, and a step wherein sensory device command metadata are generated corresponding to the sensory effect information; the sensory device command metadata include sensory device command technology information for commanding the sensory device. According to the present invention, sensory effects are also implemented when media are provided so that the playback effects of media can be maximized.
