THE METHOD AND APPARATUS FOR FRAME ERROR CONCEALMENT, THE METHOD AND APPARATUS TO COMPOSITE METHOD OF FRAME ERROR CONCEALMENT

摘要

A kind of method and apparatus are arranged to form multiple pervious signal for hiding a frame error and a kind of method and apparatus for component frame error concealing method, to restore the frame signal that wherein a mistake is generated, to prevent from generating demodulated noise. A kind of method includes the following steps: for hiding a frame error: determining whether the mistake on a current n frameworks (200); For two similar blocks with correlation highest have primary block signal search, in the search section that n is framed in a previous frame (210) before; It includes first and second next signal to generate a combination signal that forming, which has each first and second similar block of first and second pervious signal, is used to restore n frameworks (220~240); It replicates and the combination signal for exporting generation enters at least one time (250) of n frameworks.
