Classification: G10L,H04B

Abstract:
Method for decoding a digital data stream representing an audio signal, in which at least a group of spectral components is calculated from the vector quantization indices included in the digital data stream, and where the spectral components of the said group are combined during the construction of a decoded version of the audio signal, each component of the group being associated with a set of vector quantization indices used in the calculation of this component, in which the digital data stream includes identification information for at least one pair of spectral components, each identified pair comprising a first and a second component, and where the second spectral component of at least one identified pair is associated with a set of vector quantization indices of which at least some are copied from a set of indices read from the data stream and associated with the first spectral component of the said identified pair.
