サンプルごとに正確なオーディオ信号表現のための方法、エンコーダ及びデコーダ

摘要

A method for providing information on the validity of encoded audio data is disclosed, the encoded audio data being a series of coded audio data units. Each coded audio data unit can include information on the valid audio data. The method includes: providing either information on a coded audio data level which describes the amount of data at the beginning of an audio data unit being invalid, or providing information on a coded audio data level which describes the amount of data at the end of an audio data unit being invalid, or providing information on a coded audio data level which describes both the amount of data at the beginning and the end of an audio data unit being invalid. A method for receiving encoded data including information on the validity of data and providing decoded output data is also disclosed. Furthermore, a corresponding encoder and a corresponding decoder are disclosed.
