ABSTRACT:
An audio decoding apparatus capable of preventing a buffer for storing an audio stream from overflowing is provided. The audio decoding apparatus decodes an audio stream including various kinds of coded data. The audio decoding apparatus includes a bit buffer for temporarily storing the audio stream, a decoder for receiving the audio stream from the bit buffer and decoding the audio stream to produce decoded audio data, and a data extractor, operatively coupled to the bit buffer, for extracting coded data necessary for the decoder from the audio stream and supplying the audio stream including the extracted necessary coded data to the bit buffer.
