20090216541 | Method of Encoding and Decoding an Audio Signal - An apparatus for encoding and decoding an audio signal and method thereof are disclosed, by which compatibility with a player of a general mono or stereo audio signal can be provided in coding an audio signal and by which spatial information for a multi-channel audio signal can be stored or transmitted without a presence of an auxiliary data area. The present invention includes extracting side information embedded in non-recognizable component of audio signal components and decoding the audio signal using the extracted side information. | 08-27-2009 |
20090006105 | Method for Generating Encoded Audio Signal and Method for Processing Audio Signal - A method for generating an encoded audio signal, and a method for processing the same during the multi-channel audio coding are disclosed. The present invention provides the method for generating an encoded audio signal comprising: generating basic spatial information including basic configuration information requisite for a multi-channel audio coding process and basic data corresponding to the basic configuration information; and generating extension spatial information including extension configuration information selectively required for the multi-channel audio coding process and extension data corresponding to the extension configuration information. | 01-01-2009 |
20080304513 | Method For Signaling of Splitting Information - A signaling method for signal division information is disclosed. The signaling method divides a signal into several signals, and effectively represents division information of the divided signals. The present invention provides the method signaling for signaling signal division information comprising: assigning number of lower nodes equal to the number of divisions to a lower layer if a node of an upper layer is represented by a division identifier (ID); and un-assigning any lower node to the lower layer if the node of the upper layer is represented by a non-division identifier (ID), wherein the signal division information includes the division ID and the non-division ID indicating the presence or absence of a signal division at a node of a layer. | 12-11-2008 |
20080228499 | Method For Generating Encoded Audio Signal and Method For Processing Audio Signal - A method for generating an encoded audio signal, and a method for processing the same during the multi-channel C audio coding are disclosed. The present invention provides the method for generating an encoded audio signal comprising: including fixed channel configuration information acting as configuration information of a predetermined output channel; and including arbitrary channel configuration information. | 09-18-2008 |
20080228475 | Method for Generating Encoded Audio Signal and Method for Processing Audio Signal - A method for generating an encoded audio signal, and a method for processing the same during the multi-channel audio coding are disclosed. The present invention provides the method for generating an encoded audio signal comprising: including basic configuration information requisite for a multi-channel audio coding process; and including extension configuration information, wherein the extension configuration information includes configuration information of extension environment which is identified by a type identifier (ID). | 09-18-2008 |
20080219475 | Method for Processing Audio Signal - 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. | 09-11-2008 |
