"device and method for generating a coded multichannel signal and device and method for decoding a coded multichannel signal". In a multichannel encoder that generates several different parameter sets for reconstructing a multichannel output signal using at least one transmission channel, the data rate (26) is written (25) so that two parameter sets are decodable from each other. way independent of each other. thus, a multichannel decoder can skip an optional parameter set and / or have a higher version number when reading the data rate and still perform a valid multichannel reconstruction using a required or optional set data set. a sufficiently low version number. This achieves a flexible encoder / decoder concept, suitable for future upgrades, characterized by backwards compatibility and reliability.
