ENTROPY ENCODING METHOD USING AN ADAPTIVE THRESHOLD AND AN APPARATUS USING THE SAME FOR ENCODING ENTROPY ACCORDING TO A PREDETERMINED THRESHOLD

摘要

PURPOSE: An entropy encoding method using an adaptive threshold and an apparatus using the same are provided to adaptively set up a threshold by encoding/decoding entropy and to perform entropy encoding suitable for the property of residual coefficient.;CONSTITUTION: An apparatus determines a threshold value(S400). The apparatus codes a run-mode(S410). The apparatus codes a level of coefficient which does not 0 in a run-mode. If a set threshold value is satisfied, the apparatus performs level mode coding(S420,S430).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) No; (CC) Yes; (DD) End; (S400) Determining threshold; (S410) Performing run mode coding; (S420) Whether to satisfy a set threshold?; (S430) Performing level mode coding
