Japanese Patent JP3428024
Kind Code:
B2
Abstract:
In a method and device for signal encoding according to this invention, a first encoder (124) separately encodes noise components of a plurality of channels and a second encoder (125) commonly encodes noise components of a plurality of channels. Then a discriminating means (123) detects the characteristics of the noise components and selects the output from either of the encoders (124 and 125) based on the discriminated results. When the noise components the compression ratio of the noise components of a plurality of channels can be increased. When the components are not commonly encoded, on the other hand, undesired effects of common encoding can be prevented.
