Abstract
PURPOSE: A frame erasure concealment method and an apparatus thereof are provided to efficiently perform FEC(Frame Erasure Concealment) for a frame removed in a frame transmission process. CONSTITUTION: A coding mode setting unit sets up an operation mode from a plurality of operation modes in order to encode input audio data by using a codec(26). When the operation mode is in a High FER(Frame Erasure Rate) mode, the codec encodes a current frame of the input audio data in a plurality of FEC(Frame Erasure Concealment) modes. (Reference numerals) (AA) EVS codec(enhanced NB, enhanced WB)
