Apparatus for decoding audio data with scalability and method thereof

Image Number 5 for United States Patent #7831436.

An apparatus for decoding audio data that is capable of reducing the amount of calculations that are performed during the arithmetic decoding of an audio signal coded by bit sliced arithmetic coding (BSAC) to improve the performance of a decoder and a method thereof are provided. According to the embodiments of the present invention, it is possible to reduce the amount of calculations that are performed during the arithmetic decoding of an audio signal in the BSAC to 1/16 of the amount of calculations of the conventional full search method
