Title:
符号化されたマルチチャネル信号を発生するための装置および方法並びに符号化されたマルチチャネル信号を復号化するための装置および方法
Document Type and Number:
Japanese Patent JP4856641
Kind Code:
B2
Abstract:
In a multi-channel encoder generating several different parameter sets for reconstructing a multi-channel output signal using at least one transmission channel, the data stream is written such that the two parameter sets are decodable independently of each other. Thus, a multi-channel decoder is enabled to skip a parameter set which is marked as optional and/or has a higher version number when reading the data stream and still to perform a valid multi-channel reconstruction using a data set marked as mandatory or a data set having a sufficiently low version number. This achieves a flexible encoder/decoder concept suitable for future updates characterized by backward compatibility and reliability.
