Patent ID: 7864814

Claim:
A control logic means connectable to jitter buffer means adapted to receive and buffer incoming frames or packets and to extract data frames from the received packets, to decoding means connected to the jitter buffer means adapted to decode the extracted data frames, to time scaling means adapted to play out decoded speech frames adaptively, the control logic means comprises means for obtaining knowledge of whether a state recovery function is available, means for retrieving at least one parameter from at least one of the jitter buffer means, the time scaling means, and the decoding means, means for adaptively controlling at least one of an initial buffering time of said jitter buffer means based on the at least one parameter from the jitter buffer means and the knowledge of the availability of the state recovery function, and, means for adaptively controlling a time scaling amount of said time scaling means based on the at least one retrieved parameter from the time scaling means or the decoder and the knowledge of the availability of the state recovery function.
