METHOD AND APPARATUS FOR PACKET LOSS CONCEALMENT, AND DECODING METHOD AND APPARATUS EMPLOYING SAME

摘要

A method for time domain packet loss concealment may comprise the steps of: checking whether the current frame is an erased frame and whether the erased frame is a good frame; if the current frame is an erased frame or the erased frame is a good frame, then acquiring signal characteristics; selecting a frame from among a phase-matching frame and a repetition and smoothing frame on the basis of a plurality of parameters comprising the signal characteristics; and carrying out the packet loss concealment process for the current frame by means of the selected frame.
