Patent ID: 7251241

Claim:
An apparatus comprising: one or more processors; and a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to: receive frames to be transferred to a remote endpoint; exchange signaling with the remote endpoint to identify a reconstruction mode used by the remote endpoint, the reconstruction mode specifying an algorithm used by the remote endpoint to reconstruct lost packets or other information that is not available for playout; synthesize frames corresponding to the received frames using the identified reconstruction mode to locally simulate one or more potential loss concealment attempts by the remote endpoint; compare the received frames to the synthesized frames to identify at least first and second groups of the received frames, the first group of the received frames being more completely replicated by the synthesized frames than the second group of the received frames; and transmitting a representation of the second group advantageously with respect to a representation of the first group by transmitting more redundancy bits for the frames in the second group than the frames in the first group.
