Error concealment method and apparatus for audio signal and decoding method and apparatus for audio signal using the same |
摘要 |
An error concealment method and apparatus for an audio signal and a decoding method and apparatus for an audio signal using the error concealment method and apparatus. The error concealment method includes selecting one of an error concealment in a frequency domain and an error concealment in a time domain as an error concealment scheme for a current frame based on a predetermined criteria when an error occurs in the current frame, selecting one of a repetition scheme and an interpolation scheme in the frequency domain as the error concealment scheme for the current frame based on a predetermined criteria when the error concealment in the frequency domain is selected, and concealing the error of the current frame using the selected scheme. |

1. An error concealment apparatus for an audio signal, the apparatus comprising:
an error concealment unit, implemented by a processor and configured to determine an error concealment scheme from a plurality of error concealment schemes, based on at least whether the audio signal is stationary when a frame corresponds to a current error frame or a next good frame after an error frame, and to conceal the frame based on the determined error concealment scheme. |
