Abstract
A high efficiency coding method and apparatus includes quantization which takes into account correlation of input signals of plural channels in coding the input signals of the respective channels simultaneously. In the high efficiency coding method and apparatus, spectrum data from MDCT circuits or coefficient data are transmitted to another channel via an other-channel transmission circuit, and data from another channel are transmitted to correlation adaption circuits. The data from correlation adaption on circuits are transmitted to adaptive bit allocation circuits, respectively, wherein bit allocation in coding of the input signals of one channel takes into account the input signals of another channel.
