Abstract
An error concealment method and device for recovering lost data in the AAC bitstream in the compressed domain. The bitstream are partitioned into frames each having a plurality of data parts including the header/global gain, scale factors and QMDCT coefficients. The data parts are stored in a plurality of buffers, so that if one or more data parts of a current frame is corrupted or lost, the corresponding data part in the neighboring frames is used to conceal the errors in the current frame.
