Problems solved by technology

However, this approach may not be used for media with continuous sound sources such as soap operas or movies
[0009] In addition, when sound field information is inserted into the header of an audio pack having a compressed sound source (for example, MPEG compressed sound source), the sound field information may be destroyed every time the header is destroyed by conversion and / or transmission such as format conversion
In addition, when extracting sound field information from the sound source itself, problems are: accuracy cannot be guaranteed, real-time processing may not be possible, and sound field characteristics are significantly different for most types of media
Therefore, this method is difficult to implement

Embodiment Construction

[0027] Now, embodiments of the present general inventive concept will be described in detail, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0028] The present general inventive concept provides a method of embedding a sound field control factor (hereinafter, referred to as 'SFC factor') representing a sound field characteristic of an uncompressed sound source using a watermark. Watermarked sound sources are able to maintain their sonic properties even if SFC factors are embedded in them. In addition, SFC factors are used to process the sound field, said SFC factors being decoded by an extraction method corresponding to the embedding method.

[0029] figure 2 is a block diagram showing an apparatus for embedding SFC factors into a sound source according to the present gen...

Abstract

A method of embedding sound field control factors (SFC factors) into a sound source. The method includes coding sound field factors and sound field information to obtain sound field control factors for the sound source in a binary data type, and the sound field factors represent an acoustic characteristic of the sound source and the sound field information represents an environment under which the sound source is recorded, and watermarking the sound field control factors into the sound source without compressing the sound source. In this method, the SFC factors that represent characteristics of the sound source are embedded into the sound source itself using a digital watermarking technology. Therefore, the SFC factors need not be manually set by a user. In addition, the SFC factors can be reliably transmitted, irrespective of header corruption caused by format conversion and transmission of a compressed sound source.

Description

[0001] This application claims priority from Korean Patent Application No. 2004-73367 filed on September 14, 2004 in the Korean Intellectual Property Office, which is hereby incorporated by reference in its entirety. technical field [0002] The present general inventive concept relates to a method of controlling a sound field, and more particularly, to a method of embedding sound field factors and sound field information into a sound source and a method of processing sound source factors and sound field information. Background technique [0003] Generally, transmitting sound field information for sound field processing requires the user to directly specify the sound field information. In addition, sound field information is usually inserted into the headers of packets with compressed sound sources. Sound field information can also be extracted from the sound source itself. [0004] A user specifies sound field informa...
