a buffer/deformat for delaying a coded input signal for a designated time; a VLD for decoding the coded image data and producing various kinds of error flags; an error decoder for ascertaining the presence of an error in a picture start code, a slice start code and a macro block type so as to determine the logic values of a first error bit; and a second error bit; a first error corrector for generating a corrected information of the macro block; an adverse DCT for adverse-DCT processing; a adding machine for adding the output signal of the adverse-DCT to the output signal of the movement compensator; a third error corrector for generating a corrected information of the movement vector from the second and the third error bits; a movement compensator for supplying an estimated movement vector; and a second error corrector for controlling the switching of the switches so as to correct the errors of the macro block type. |
