ABSTRACT:
A media over packet networking appliance provides a network interface, a voice transducer, and at least one integrated circuit assembly coupling the voice transducer to the network interface. The at least one integrated circuit assembly provides media over packet transmissions and holds bits defining reconstruction of a packet stream having a primary stage and a secondary stage. The secondary stage has one or more of linear predictive coding parameters, long term prediction lags, parity check, and adaptive and fixed codebook gains. The packet stream has an instance of single packet loss, and the reconstruction includes receiving a packet sequence represented by P(n)P(n−1)′, [Lost Packet], P(n+2)P(n+1)′, and P(n+3)P(n+2)′, obtaining as information from the secondary stage one or more of the linear predictive coding parameters, long term prediction lags, parity check, and adaptive and fixed codebook gains, and performing an excitation reconstruction utilizing said packet sequence thus received.
