信号処理方法及び装置
Document Type and Number:
Japanese Patent JP2011504250
Kind Code:
A
Abstract:
A method and apparatus for processing a signal are discussed. According to an embodiment, the method includes receiving extension information and a downmix signal decoded by either an audio coding scheme or a speech coding scheme, the downmix signal having a bandwidth of a low frequency signal; generating an upmixing signal from the downmix signal by using channel extension; determining an extension base signal corresponding to partial band of the upmixing signal based on the extension information; and generating an extended upmixing signal by applying the extension information to the extension base signal, the extended upmixing signal having a bandwidth extended by reconstructing a high frequency signal.
