PROBLEM TO BE SOLVED: To provide a method for the transfer error concealment of a digital signal divided into a plurality of continuous frames associated with different time intervals in which a deletion frame and a valid frame are included in a signal in reception, and at least two steps are executed for displacing at least a first deletion frame (N) after the valid frame, and a first step (E1) of preparation includes at least one analysis of a valid decoded signal without generating a missing sample, and a second step (E2) of concealment includes generating the missing sample of a signal corresponding to the deletion frame.SOLUTION: A first step and a second step are executed with different time intervals. This invention relates to a concealment device for executing the method and a decoder having such a device. This invention makes it possible to disperse the complexity of error concealment with different time intervals. |
