Abstract  Abstract

providing a terminal and method for audio coding. the terminal comprises: a coding mode setting unit from a plurality of operation modes provided for operation mode for encoding the input audio data by the codec; A codec is configured to encode the input audio data based on the set operating mode such that when the mode of operation is a high frame erasure rate (FER) mode of operation coder and decoder according to the one or more frame erasure concealment (FEC) mode in one FEC mode the current frame of the input audio data. the encoding mode setting unit sets the operation mode is the high FER mode of operation the one or more FEC mode encoding mode setting unit from the high FER mode of operation a predetermined select said one FEC mode. The one FEC mode selection combining redundant based on the encoding of the input audio data or the input audio coded separating redundant information to control the codec.

An audio coding terminal and method is provided. The terminal includes a coding mode setting unit to set a mode of operation from plural modes of operation for coding by a codec of input audio data and the codec configured to code the input audio data based on the set mode of operation such that when the set mode of operation is a high frame erasure rate (FER) mode of operation the codec codes a current frame of the input audio data according to one frame erasure concealment (FEC) mode of one or more FEC modes. Upon the coding mode setting unit setting the mode of operation to be the High FER mode of operation the coding mode setting unit selects the one FEC mode from the one or more FEC modes predetermined for the High FER mode of operation to control the codec based on an incorporating of redundancy within a coding of the input audio data or as separate redundancy information separate from the coded input audio according to the selected one FEC mode.
