摘要： A method and apparatus to encode/decode an audio signal, in which a bit rate for each bit plane can be controlled. A method of encoding an audio signal for each of a plurality of bit plane can include dividing the audio signal into a plurality of frequency bands and encoding the bit planes of the frequency bands from a low frequency band to a high frequency band, wherein, in the encoding the bit planes of the frequency bands, the bit planes are encoded from the most significant bit (MSB) to the least significant bit (LSB) within bits allocated for the frequency bands, and when there are allocated bits remaining after the encoding of the currently encoded frequency band, un-encoded bit planes corresponding to the MSB in a frequency band that has the fewest encoded bit planes among frequency bands with a lower frequency than the currently encoded frequency band are encoded using the remaining allocated bits. Accordingly, when encoding/decoding an audio signal, an encoding sequence of bit planes is determined so that an audio signal that significantly affects audio quality during decoding is first encoded, thereby reducing audio quality deterioration at a low bit rate.

摘要： Provided is a scalable encoding method, apparatus, and medium. The method includes: encoding a base layer and encoding a first enhancement layer and a second enhancement layer in a frame having the base layer; and generating an encoded frame by synthesizing the encoded results. Accordingly, only if the loss of the encoding frame is not as great as the encoded first enhancement layer is damaged, a case where speech restoration with respect to partial frequency bands must be given up does not occur. Furthermore, since an encoder divides the second enhancement layer into a plurality of layers considering a distribution pattern of data belonging to the second enhancement layer and first encodes a layer in which lots of data are distributed among the divided layers, loss of audio information can be minimized even if a portion of the encoded second enhancement layer is damaged.

摘要： A method and an apparatus for encoding/decoding a digital signal are provided. First, a digital input signal is transformed into samples to remove redundant information among signals. Then, a lookup table corresponding to a characteristic of the input signal is selected among a plurality of lookup tables that indicate different numbers of bits allocated for each quantization unit depending on different characteristics of input signals, and the number of bits allocated for each quantization unit is acquired from the selected lookup table. Next, a distribution of samples within each quantization unit is divided into a predetermined number of sections, and the samples are linearly quantized using the allocated number of bits on a section-by-section basis. Thereafter, a bitstream comprised of frames is produced from the quantized samples and predetermined side information so that information about a frame length is stored in the end of frame.
