Patent ID: 7590249

Claim:
An object-based three-dimensional audio terminal system comprising: an audio decoding unit demultiplexing and decoding a multiplexed audio signal including object sounds, background sounds, and scene information applied through a medium wherein the audio decoding unit comprises a demultiplexer for demultiplexing data applied through the medium and multiplexed to separate them into background sound object data, sound source data, and audio scene information data and a decoder for decoding the background sound object data, the sound source data, and the audio scene information data separated by the demultiplexer; an audio scene-synthesizing unit selectively synthesizing the object sounds with the audio scene information decoded by the audio decoding unit into a 3-D audio scene under the control of a user, the audio scene-synthesizing unit including a sound source object processor for receiving the background sound objects, the sound source objects and the audio scene information data and an object mixer for mixing the sound source objects processed by the sound source object processor with the background sound objects decoded by the audio decoding unit to output the results; a user control unit providing a user interface so as to selectively synthesize the audio scene by the audio scene synthesizing unit under the control of the user, wherein the sound source object processor further includes a motion processor analyzing a plurality of sound source data and the audio scene information, calculating a location of each sound source object moving with its particular trajectory, and modifying its trajectory under the control of the user through the user control unit; and an audio reproducing unit reproducing the 3-D audio scene synthesized by the audio scene-synthesizing unit.
