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: The apparatus for the inter-object regeneration relation and volume information storage and interpretive method and this easily can easily force and restriction of the object-based audio service by advance defining the force/constraint condition about the regeneration relation of inter-object and replay volume. CONSTITUTION: The object-based audio player(101) inputs the audio object information and the force/condition information included within the object-based audio file(102) to the force/condition information Analysis module. Object the audio track or the group. The combination generation consisting of the group is the audio track or group. The force/condition information Analysis module(103) interprets and the magnetic track decoded before the decryption algorithm of the audio object is or reject adopted.
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:
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 for storing and analyzing play relation between objects for an object based audio service and volume information and a device thereof are provided to predefine and store play relation between objects and forcible/constraint conditions for play volume and enable a terminal to efficiently analyze the forcible/constraint conditions and the play relation. CONSTITUTION: An object based audio player(101) inputs audio track information and forcible/constraint information included in an object based audio file(102) to a forcible/constraint information analyzing module(103). The forcible/constraint information analyzing module analyzes the inputted information to select a track to be decoded. The forcible/constraint information analyzing module constrains play volume information of a track in a mixing step. An operation of an object based audio player to which forcible/constraint information is reflected is performed.
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.
