Method and apparatus for providing coder independent packet replacement

摘要

A method and apparatus for providing coder independent packet replacement in the presence of frame erasures without requiring that modifications be made to either the encoder or the decoder. An input buffer management process identifies the presence of lost or missing packets and informs a playout buffer management process therof. Then, when packets have been lost, the playout buffer management process advantageously synthesizes an actual signal segment in the absence of a corresponding decoded packet.
