1. A frame error concealment method comprising:
- selecting one mode from among a plurality of modes associated with repetition and smoothing, for a frame in a time domain signal generated after time-frequency inverse transform processing; and
performing a corresponding time domain error concealment processing on the frame based on the selected mode,wherein the frame is classified as a current error frame or a next good frame after a single error frame or a next good frame after a burst error frame, andwherein the plurality of modes include a first mode related to the current error frame, a second mode related to the next good frame after the single error frame, and a third mode related to the next good frame after the burst error frame.

Abstract
Disclosed is a frame error concealment (FEC) method. The method includes: selecting an FEC mode based on states of a current frame and a previous frame of the current frame in a time domain signal generated after time-frequency inverse transform processing; and performing corresponding time domain error concealment processing on the current frame based on the selected FEC mode, wherein the current frame is an error frame or the current frame is a normal frame when the previous frame is an error frame.
