ABSTRACT:
In response to an error signal from a source of an MPEG audio data stream, a decoder replaces data with an error code and temporarily enables error handling. The error code is a valid bit combination rarely found in MPEG audio data frames. During audio decoding with error handling enabled, the decoder checks for the error code and replaces the error code with reconstructed data. Typically, some subband data are replaced with zeros so that an error only changes some of the frequency components.
