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 1):
A method for updating an audio decoder state, the method comprising:\n storing, by an audio decoder, decimated state data associated with decoding of stored encoded bits, from a decoder history buffer, the state data decimated by a decimation factor associated with a down-sampling output rate of the audio decoder, the encoded bits included in a sequence of encoded audio packets to generate output audio samples; updating the state of the audio decoder based on state data retrieved from the decoder history buffer, the retrieved state data associated with the decoding of the encoded bits and further associated with a first time equal to or earlier than a second time associated with concealment samples selected from a group of previous output audio samples; and re-decoding, by the audio decoder, the stored encoded bits associated with the retrieved state data, the state of the audio decoder further updated during the re-decoding.
