METHOD AND APPARATUS FOR MULTISTEP QUANTISATION Russian patent published in 2012 - IPC G10L19/12 G10L19/14

Abstract RU 2453932 C2

FIELD: information technology.

SUBSTANCE: invention relates to data compression techniques, particularly a method and apparatus for multistep quantisation. The result is achieved due to that, in the method for multistep quantisation, a reference codebook is obtained in accordance with the codebook of the previous step, the codebook of the current step is obtained in accordance with the reference codebook and a scaling factor, and the input vector is quantised using the codebook of the current step.

EFFECT: saving memory and more efficient use of resources.
