Abstract
As an encoded signal for transmission to a packet communication network or an ATM communication network, signals of a plurality of frequency subbands are independently encoded in units of frames, and an encoded bit rate is controlled in that frame unit. The deterioration of quality due to cell discarding is light, and an improvement in encoding efficiency can be expected through the joint use of entropy coding processing.
