Abstract:
The present document relates to a method of layered encoding of a compressed sound representation of a sound or sound field. The compressed sound representation comprises a basic compressed sound representation comprising a plurality of components, basic side information for decoding the basic compressed sound representation to a basic reconstructed sound representation of the sound or sound field, and enhancement side information including parameters for improving the basic reconstructed sound representation. The method comprises sub-dividing the plurality of components into a plurality of groups of components and assigning each of the plurality of groups to a respective one of a plurality of hierarchical layers, the number of groups corresponding to the number of layers, and the plurality of layers including a baselayer and one or more hierarchical enhancement layers, adding the basic side information to the base layer, and determining a plurality of portions of enhancement side information from the enhancement side information and assigning each of the plurality of portions of enhancement side information to a respective one of the plurality of layers, wherein each portion of enhancement side information includes parameters for improving a reconstructed sound representation obtainable from data included in the respective layer and any layers lower than the respective layer. The document further relates to a method of decoding a compressed sound representation of a sound or sound field, wherein the compressed sound representation is encoded in a plurality of hierarchical layers that include a base layer and one or more hierarchical enhancement layers, as well as to an encoder and a decoder for layered coding of a compressed sound representation.

Claim (Index 18):
The apparatus of any one of  claims 10 - 17 , wherein the base layer includes at least one portion of additional basic side information corresponding to a respective layer and including information that specifies decoding of one or more components among the components assigned to the respective layer in dependence on other components assigned to the respective layer and any layers lower than the respective layer, the method comprising, for each portion of additional basic side information:\n decoding the portion of additional basic side information by referring to the components assigned to its respective layer and any layers lower than the respective layer; and correcting the portion of additional basic side information by referring to the components assigned to the highest usable layer and any layers between the highest usable layer and the respective layer, wherein the basic reconstructed sound representation is obtained from the components assigned to the highest usable layer and any layers lower than the highest usable layer, using the basic side information and corrected portions of additional basic side information obtained from portions of additional basic side information corresponding to layers up to the highest usable layer.
