摘要： A method and device to arithmetically decode scalable bit sliced arithmetic coding (BSAC) audio data are provided. The arithmetic decoding method includes checking whether all side information of a last layer of the BSAC audio data is to be decoded, and performing BSAC smart decoding and terminating the decoding when all the side information of the last layer is not decoded, and terminating decoding of the last layer when all the side information of the last layer is decoded. The BSAC smart decoding includes checking whether a symbol to be decoded is determined regardless of data read after the truncated bitstream, continuing the decoding when decoding can be performed regardless of data read after the truncated bitstream, and determining that ambiguity occurs and terminating the decoding, when the symbol to be decoded is determined dependent on the data read after the truncated bitstream. Accordingly, byte level scalability can be provided in a MPEG-4 BSAC decoder. Even though the bitstream is truncated, the decoding termination time can be known, and additional decoding with respect to a truncated portion of the bitstream can be performed.

摘要： An method and apparatus to extract an audio signal having an important spectral component (ISC) and a low bit-rate audio signal coding/decoding method using the method and apparatus to extract the ISC. The method of extracting the ISC includes calculating perceptual importance including an SMR (signal-to-mark ratio) value of transformed spectral audio signals by using a psychoacoustic model, selecting spectral signals having a masking threshold value smaller than that of the spectral audio signals using the SMR value as first ISCs, and extracting a spectral peak from the audio signals selected as the ISCs according to a predetermined weighting factor to select second ISCs. Accordingly, the perceptual important spectral components can be efficiently coded so as to obtain high sound quality at a low bit-rate. In addition, it is possible to extract the perceptual important spectral component by using the psychoacoustic model, to perform coding without phase information, and to efficiently represent a spectral signal at a low bit-rate. In addition, the methods and apparatus can be employed in all the applications requiring a low bit-rate audio coding scheme and in a next generation audio scheme.

摘要： A method of and an apparatus for encoding/decoding an MPEG-4 bit sliced arithmetic coding (BSAC) audio bitstream having ancillary information. A time domain audio signal is converted to a frequency domain audio signal and quantized. A number of data bits is counted and a number of available bits per layer is obtained. The number of available bits per layer is modified considering the size of ancillary information. Actual audio data is encoded in units of layers and ancillary information is embedded in the encoded bitstream. A header is decoded and a layer structure of an audio bitstream is calculated to determine the size of the ancillary information as a difference between a size of data up to a top layer and a size of a frame. The ancillary information is extracted to improve meta data and sound quality of audio contents.
