Abstract

An apparatus and method for adapting an audio signal is provided. The apparatus adapts the audio signal to a usage environment including user's characteristic, terminal capacity and user's natural environments responsive to user's adaptation request, to thereby provide the user with a high quality of digital contents efficiently.

Description

technical field [0001] The present invention relates to an apparatus and method for adapting an audio signal; and, more particularly, to an apparatus and method for adapting an audio signal to different usage environments such as user characteristics, user's natural environment, and user terminal capabilities. Background technique [0002] The Moving Picture Experts Group (MPEG) has proposed a new standard work item, Digital Item Adaptation (DIA). A Digital Item (DI) is a structured digital object with standard representation, authentication and metadata, and DIA refers to the process for generating an adapted DI by modifying the DI in a source adaptation machine and / or a descriptor adaptation machine. [0003] Here, a source refers to an asset that can be identified individually, such as a video or audio clip, image or textual asset. A source can also represent a physical object. A descriptor refers to information related to a DI component or some of its items. Likewise,...
