Abstract:
Techniques are provided for updating state data of an audio decoder for packet loss concealment (PLC). A methodology implementing the techniques according to an embodiment includes decoding encoded bits in a sequence of audio packets. A decoder history buffer stores the encoded bits and decimated state data associated with the decoding of those bits. The decimation factor of the state data is based on a down-sampling rate of the decoder. The method further includes performing PLC for an invalid audio packet using concealment samples from a PLC history buffer. The state of the audio decoder is updated from the decoder history buffer, based on timing associated with the concealment samples. The method further includes re-decoding the stored encoded bits associated with the updated state data, to further update the state of the audio decoder for subsequent decoding of a valid audio packet following the invalid audio packet.

Claim (Index 17):
The computer readable storage medium of  claim 16 , wherein the concealment samples are selected from a group of previous output audio samples stored in a packet loss concealment (PLC) history buffer.
