Abstract:
프리셋을 이용한 객체기반 오디오 시스템, 객체기반 오디오 제공 방법 및 객체기반 오디오 재생 방법이 개시된다. 객체기반 오디오 시스템은 객체기반 오디오 파일의 저장 위치를 참조하는 참조 정보를 제공하는 참조 정보 제공부 및 객체기반 오디오 파일을 구성하는 적어도 하나의 오디오 객체를 제어하기 위한 프리셋 정보를 제공하는 프리셋 정보 제공부를 포함한다.
Abstract:
PURPOSE: A system and a method of grouping tracks inside a file are provided to group presentation metadata when multimedia tracks include overlapped presentation metadata, thereby storing the grouped metadata in a file. CONSTITUTION: A plurality of multimedia tracks is saved according to a file format like the ISO file format. The multimedia tracks are compressed in the same encoding method. If parts of presentation metadata information about an included audio track are the same, the metadata information is displayed using a group box not to overlappingly save the metadata information.
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 method for generating/reproducing object-based audio contents and a computer-readable recording medium in which data having a file format structure for an object-based audio service is recorded are provided to store presets for plural audio objects efficiently. CONSTITUTION: A method for generating/reproducing object-based audio contents comprises the following steps of: receiving plural audio objects(310); generating at least one preset by using the received audio objects(320); storing a preset parameter about attributes of at least one preset and the audio objects in a box type(330).
Abstract:
PURPOSE: An object-based audio system, an object-based audio providing method and an object-based audio play system using preset are provided to control the audio objects constituting an object based audio file by providing preset information for controlling the audio object. CONSTITUTION: A reference information provider(310) provides the reference information for controlling an audio object constituting an object based audio file. The object based audio file is provided based on the reference information. The object based audio file is reproduced based on the preset information, and the preset information and the reference information are provided by being stored a preset file of an object-based box structure.
Abstract:
PURPOSE: A method and an apparatus for generating and playing an object based audio contents are provided to continuously play plural object-based audio contents according to the same audio preset. CONSTITUTION: A preset generating unit(110) generates an audio preset, and the audio preset includes the information on the plural audio objects which constitute audio contents. A preset ID setup unit(120) sets up the preset ID of the generated audio preset, and an encoding unit(140) encodes the plural audio objects, the audio preset and the preset ID. The encoding unit generates the object based audio contents.
