Patent ID: 8145498

Claim:
A device for generating a coded multi-channel audio signal representing an uncoded multi-channel audio signal comprising N original channels, wherein N is equal to or larger than 2, comprising: a unit for providing parameter information for reconstructing K output audio signal channels from M transmission channels, wherein M is equal to or larger than 1 and less than N, wherein K is larger than M and equal to or less than N, wherein the parameter information comprises at least one first parameter set and a different second parameter set for reconstructing one and the same output channel, wherein the second parameter set comprises associated syntax version information; and a unit for writing a data stream, wherein the unit for writing is designed to write the first and the second parameter sets into the data stream so that a reconstruction of at least one of the K output channels is performable by a decoder using the first parameter set and using at least one of the M transmission channels and without using the second parameter set, wherein the unit for writing is configured to write length information indicating an amount of data of the second parameter set into the data stream, and wherein the unit for providing or the unit for writing comprises a hardware implementation.
