FRAME BIT APPARATUS

摘要

an perceptual entropy calculating unit(220) for calculating the perceptual entropy from the frame group(210) which has a multiple frames; an adaptive frame bit allocation unit(230) for allocating the bit of a frame adaptively in the frame group responding to the perceptual entropy; and a coder(240) for coding inputted multiple frames with allocating bits so as to increase a coding efficiency and improve a sound quality.
