Abstract

PROBLEM TO BE SOLVED: To produce more effective 3D sounds by extending spatiality of sound sources of contents. SOLUTION: An illustrated sound source forms a plane sound source including an area of Δy×Δz by being extended vertically to a vector defined in a "direction" field based on "source Dimension" field values (0, Δy, Δz). Thus, when the dimension and location of the sound source are defined, a point sound source is located on a surface of the extended sound source. In the present invention, the locations of the point sound sources are calculated so as to be distributed uniformly on the surfaces of the extended sound source. COPYRIGHT: (C)2008,JPO&INPIT

Description

technical field [0001] The present invention relates to a method for processing a three-dimensional audio scene with sound sources whose spatiality is extended, in particular to a method for processing a three-dimensional audio scene to extend the spatiality of sound sources in a three-dimensional audio scene Methods. Background technique [0002] Generally, the content providing server encodes the content with a predetermined encoding method and sends the encoded content to the content consumption terminal that consumes the content. The content consumption terminal decodes the content in a predetermined decoding method and outputs the transmitted content. [0003] Therefore, the content providing server includes an encoding unit for encoding content and a sending unit for sending the encoded content. On the other hand, the content consumption terminal includes a receiving unit for receiving the transmitted encoded content, a decoding unit for decoding the encoded content,...
