Apparatus and method for applying a waveform prediction sub-band perceptual coding systems

摘要

(57) Abstract The divided zone perception coded system which uses the corrugated predictive coding which is generalized in frequency zone is offered in order furthermore to make the signal intelligence important matter decrease which is encoded. Rank of the estimate vessel is selected in order estimate precision and the important matter for quick answering time to make balance. Predictive coding is prohibited be adapted inside the band in interval the interval where predictive coding profit is not actualized.
