摘要:
Provided are a coding device, a decoding device, and methods thereof, with which it is possible to implement high sound quality coding and decoding in layered coding (scalable coding or embedded coding) wherein each layer comprises a plurality of bit rates (multi-rate). In the coding device (100), a feature analysis unit (101) extracts feature values of an input signal. Then a bit rate determination unit (102) determines, on the basis of the feature values of the input signal, a combination of a coding rate (low region coding rate) of a low region signal coding unit (104) which carries out coding of a low region part of the input signal and a coding rate (high region coding rate) of a high region signal coding unit (105) which carries out coding of a high region part of the input signal.
