Abstract: An object-based audio service is provided to improve the service functions, and easily access to the audio contents. An audio encoding apparatus(500) receives a plurality of audio objects comprising the audio content, and produces a plurality of frames about each object(500-502). The audio encoding apparatus groups the produced plurality of frames by playout time, and generates the corresponding index according to the frame group(506). Then, the audio encoding apparatus stores the grouped frames as an object data, stores the corresponding index information to the header, and produces multiple object audio contents(508).

Abstract: An object-based 3-dimensional audio service providing system and method using preset audio scenes are provided to offer previously generated preset audio scenes to users such that the users do not personally control audio signals and easily use object-based audio service. A 3-dimensional audio service providing system includes an audio input unit(31), an audio scene generator(32), an encoder(33), and a transmitter(34). The audio input unit receives an audio signal. The audio scene generator extracts object audio signals from the received audio signal, arranges the extracted object audio signals in a 3-dimensional space, and edits attributes of the object audio signals to generate at least one 3-dimensional audio scene. An encoder encodes the audio signal and the 3-dimensional audio scene. The transmitter converts the encoded object-based 3-dimensional audio scene according to a transmission format and transmits the object-based 3-dimensional audio scene to an audio playing terminal(40) through a digital broadcasting network(50).
