Embodiment Construction

[0014] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0015] The signaling method of segmentation information (also referred to as "separation information") according to the present invention will be described below with reference to the accompanying drawings.

[0016] The signaling method of segmented information according to the present invention is classified according to the signal category.

[0017] Before describing the present invention, it should be pointed out that the signal is configured in various ways, such as blocks, frequency bands and channels. The "signaling method" may include the meaning of "signaling" or the meaning of "identifying the signaling signal".

[0018] The term "node" is a point indicating whether a signal is split or not.

[0019] The term "spatial information" is information capable of downmixing or upmixing a multi-channel signal. ...

Abstract

A method for processing an audio signal during the multi-channel audio coding is disclosed. The present invention provides the method for processing an audio signal comprising: generating a fixed output channel using a down-mix signal and a basic matrix; and generating an arbitrary output channel using the fixed output channel and a post matrix.

Description

technical field [0001] The present invention relates to a multi-channel encoding method, in particular to a method for processing audio signals. Background of the invention [0002] In general, signals can be configured in various ways (eg, blocks, frequency bands, and channels). During static periods in which the signal can maintain predetermined statistical properties, the signal can be processed without dividing it into units, as this is advantageous for compressing the signal. [0003] It is preferable to process the signal in a segmented manner during transient periods in which the signal characteristics change abruptly, since signal distortion is prevented. [0004] However, if the user wants to process the aforementioned signal in a divided manner, there is no detailed method of signaling the divided information. Therefore, it is difficult to efficiently process the signal. Contents of the invention [0005] Accordingly, the present invention is directed to a met...
