    摘要: 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.

    摘要: An apparatus for decoding an audio signal and method thereof are disclosed. The present invention includes receiving the audio signal and spatial information, identifying a type of modified spatial information, generating the modified spatial information using the spatial information, and decoding the audio signal using the modified spatial information, wherein the type of the modified spatial information includes at least one of partial spatial information, combined spatial information and expanded spatial information. Accordingly, an audio signal can be decoded into a configuration different from a configuration decided by an encoding apparatus. Even if the number of speakers is smaller or greater than that of multi-channels before execution of downmixing, it is able to generate output channels having the number equal to that of the speakers from a downmix audio signal.
