ABSTRACT:
The present invention relates to a method for correcting errors in a data frame including horizontal parity data enabling correction of errors in the rows of the frame based on horizontal syndromes calculated on the rows, and vertical parity data enabling correction of errors in the columns of the frame based on vertical syndromes calculated on the columns. The method includes the steps of calculating, on the fly, the horizontal and vertical syndromes of a current frame on the data of the current frame being received in a slow memory, storing these syndromes in a fast memory area, and, as the data of the next frame are being received in the slow memory, finding the values and positions of the errors of the current frame based on the syndromes stored in the fast memory area.
