Abstract:
1. A device for generating a data stream for a multi-channel reconstruction of an original multi-channel signal, wherein the multi-channel signal comprises at least two channels, comprising: a fingerprint generator for generating fingerprint information from at least one base channel derived from the original multi-channel signal, wherein a number of base channels is equal to or larger than 1 and less than a number of channels of the original multi-channel signal, wherein the fingerprint information gives a progress in time of the at least one base channel; and a data stream generator for generating a data stream from the fingerprint information and of time-variable multi-channel additional information which, together with the at least one base channel, allow the multi-channel reconstruction of the original multi-channel signal, wherein the data stream generator is formed to generate the data stream so that a time connection between the multi-channel additional information and the fingerprint information may be derived from the data stream.
