AUDIO PACKET RECEIVER, AUDIO PACKET RECEIVING METHOD AND PROGRAM

摘要

The audio packet receiver according to the present invention includes a buffer unit (101) for extracting audio coded data from an audio packet and storing the extracted audio coded data into a buffer, and also for detecting the packet loss; a distance calculating unit (102) for calculating the distance between a location in the buffer unit (101) where the packet loss is detected and a location where the next audio coded data is stored; a controlling unit (103) for determining a gain value of the audio data for the concealed audio based on the distance calculated at the distance calculating unit (102); and a decoding unit (104) for performing audio error concealment based on the gain value of the audio data for the concealed audio that is determined by the controlling unit (103).
