摘要

FIELD: audio equipment.;SUBSTANCE: invention relates to the field of sound decoding. Bit stream decoding device comprises: selection unit configured to select, based on the parameter from the bit stream, one of the first and second decoding units; the first decoding unit, configured to decode the bitstream without the interframe prediction; the second decoding unit, configured to decode the bit stream with interframe prediction for the audio or speech recovering; wherein the first decoding unit comprises the dequantization unit with the array structure with limitation by units and the intraframe prediction module; at that, both the first decoding unit and the second decoding unit are configured to perform decoding using the identical number of bits per frame and perform the bitstream decoding, which is obtained based on the vocalized coding mode from the coding modes plurality.;EFFECT: technical result is increase in the bitstream decoding efficiency.;4 cl, 38 dwg, 9 tbl
