Abstract:
1. A device for generating a multi-channel signal using input data which include transmission channel data representing M transmission channels and parameter data to obtain K output channels, wherein the M transmission channels and the parameter data together represent N original channels, wherein M is less than N and equal to or larger than 1, and wherein K is larger than M, wherein the input data comprise a parameter configuration cue, comprising: a multi-channel reconstructor designed to generate the K output channels from the transmission channel data and the parameter data; and a configurator connected to the multi-channel reconstructor, wherein the configurator is adapted to configuring the multi-channel reconstructor, wherein the configurator is designed to read the input data to interpret the parameter configuration cue, when the parameter configuration cue has a first meaning, extract configuration information contained in the input data and effect a configuration setting of the multi-channel reconstructor, and when the parameter configuration cue has a second meaning differing from the first meaning, configure the multi-channel reconstructor using information on a coding algorithm with which the transmission channel data have been decoded from a coded version thereof so that the configuration setting of the multi-channel reconstructor is identical to a configuration setting of the coding algorithm or depends on a configuration setting of the coding algorithm, wherein the multi-channel reconstructor or the configurator comprises a hardware implementation.
