Method and apparatus for applying waveform prediction to subbands of a perceptual coding system

(57) In order to reduce further the requirements for signaling information by which summary coding was carried out, the division zone consciousness coding system using waveform prediction coding generalized in the frequency band is offered. The rank of a prediction machine is chosen so that predictive accuracy and the requirements to rapid response time may be balanced. Between the intervals at which a prediction-coding profit is not realized, prediction coding is forbidden accommodative within a band.
