Late frame recovery method

A method of processing communication signals, comprising:

• receiving a transmitted encoded media data stream comprising a plurality of data elements, each data element representing a portion of a transmitted media session;
• if a late data element is not received by a specified deadline, generating an estimated media sample corresponding to the late data element;
• updating a decoder state based on the estimated media sample;
• and
• if the late data element is subsequently received after the specified deadline, updating the decoder state based on the late data element, wherein if the late data element is received after the specified deadline, the data element is not decoded.

A receiver for processing transmitted media data, comprising:

• a decoder operable to decode transmitted media data elements, the decoder being operable to store and update a state of the decoder;
• and
• a late data element recovery engine, wherein if a late data element is not received by a specified deadline, the late data element recovery engine is operable to generate an estimated media sample corresponding to the late data element and the decoder is operable to update the decoder state based on the estimated media sample;
• wherein if the late data element is subsequently received after the specified deadline, the decoder is operable to decode the late data element to generate a decoded media sample, and wherein the decoder is operable to update the decoder state based on the decoded media sample.

A receiver for processing transmitted media data, comprising:

• a decoder operable to decode transmitted media data elements, the decoder being operable to store and update a state of the decoder;
• and
• a late data element recovery engine, wherein if a late data element is not received by a specified deadline, the late data element recovery engine is operable to generate an estimated media sample corresponding to the late data element and the decoder is operable to update the decoder state based on the estimated media sample;
• wherein if the late data element is subsequently received after the specified deadline, the decoder is operable to update the decoder state based on the late data element, and the data element is not decoded by the decoder.

A receiver for processing transmitted media data, comprising:

• a jitter buffer operable to receive and store each transmitted media data element until a deadline specified for the data element is reached, at which time the data element is provided to the decoder;
• a decoder operable to decode transmitted media data elements, the decoder being operable to store and update a state of the decoder;
• and
• a late data element recovery engine, wherein if a late data element is not received by a specified deadline, the late data element recovery engine is operable to generate an estimated media sample corresponding to the late data element and the decoder is operable to update the decoder state based on the estimated media sample;
• wherein if the late data element is subsequently received after the specified deadline, the decoder is operable to update the decoder state based on the late data element.
