Abstract (en)

[origin: WO2006006812A1] The present research, which relates to a terminal an method for separating audio objects from a combined audio stream, suggests a node structure that can separate audio objects which are compressed into one elementary stream b using Binary Format Scene and provides a terminal capabl of separating the audio objects from the combined audio stream by using the suggested node structure, and a metho thereof . The terminal includes: a decoder for decoding a elementary stream having audio objects compressed therei to thereby produce a decoded audio stream; and a composito for separating the audio objects from the decoded audi stream by using an audio object separation node, an forming an audio scene by using the separated audio objects wherein the audio object separation node includes: a fiel for describing the number of audio objects to be separated; and a field for describing whether to perform objec separation.
