摘要

an audio decoder to provide a decoded audio signal representation based on an encoded audio signal representation is configured to adjust decoding parameters depending on configuration information and is also configured to decode one or more audio frames using current configuration information. the audio decoder is configured to compare configuration information in a configuration structure associated with one or more frames to be decoded by the current configuration information, and make a transition to perform a decoding using the configuration information in the associated configuration structure with the one or more frames to be decoded as a new configuration information if the configuration information in the configuration structure associated with the one or more frames to be decoded, or a relevant portion of the configuration information in the configuration structure associated with the one or more frames to be decoded, is different from the current configuration information. the audio decoder is configured to consider a stream identifier information included in the configuration structure when comparing the setup information, such that a difference between a stream identifier previously acquired by the audio decoder and a stream identifier represented by the stream information flow identifier in the configuration structure associated with the one or more frames to be decoded causes the transition to be made.
