Apparatus and method for decoding audio signal coding in a DSP system having a memory

摘要

A deciding apparatus and method for deciding an audio signal coding system. A digital signal processor receives a coded audio signal, selects a specific coding system for the coded audio signal based on a predetermined portion of a data sequence of additional data of the audio signal, and decodes the audio signal using the selected coding system. A memory stores decoded programs for decoding the coded audio signal.
