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).

Abstract:
Disclosed are an object-based audio system using preset, an object-based audio providing method, and an object-based audio playback method. The object-based audio system includes a reference information providing unit providing reference information referring a storage position of an object-based audio file and a preset information providing unit providing preset information to control one or more audio objects forming the object-based audio file.
Abstract:
PURPOSE: A system for extending user interface and a method thereof, and a recording medium storing the same are provided to extend the user interface of a limited smart terminal by enabling a user using the smart terminal to use a peripheral input/output device. CONSTITUTION: A master (100) generates or manages session between user peripheral devices in order to extend user interface to the user peripheral device including a user terminal. An input/output device (200) includes the user terminal. The input/output device is inputted with a command to control the user peripheral device included in the session generated or managed in the master. The input/output device outputs or performs the command to control the user peripheral device delivered through the session.
