Abstract
In a method, apparatus and system for transmitting packet loss concealment (PLC) information, a subscriber device divides a voice sample into a plurality of packets, each including a plurality of successive frames having portions of the voice sample. The subscriber device determines if a predetermined look ahead time duration from the final frame of the plurality of successive frames in a current packet of the plurality of packets includes a noise to voice transition. When the predetermined look ahead time duration is determined to include the noise to voice transition, the subscriber device packs packing information regarding the predetermined look ahead time duration into the current packet. Finally, the subscriber device encodes the plurality of successive frames into the current packet for transmission.
