Abstract
A data shuffling method for shuffling data for rearranging predetermined data which are contained in a plurality of data units in predetermined numbers each and can be interpolated by using adjoining data in a two-dimensional array comprised of these data units so as to facilitate concealment of data errors occurring during transmission. The method includes the steps of: dividing the two-dimensional array into a plurality of processing units each containing a predetermined number of the data units; establishing correspondence between each of the predetermined data and each serial number indicating the position of each of the predetermined data in each the processing units for every processing unit; calculating for every processing unit each of the sums or differences of each of the serial numbers corresponding to each of the predetermined data with a predetermined coefficient; calculating for every processing unit each of the values of the remainder system of each of the sums or the differences with respect to the maximum value of the serial numbers; and arranging each of the predetermined data corresponding to each of the values of the remainder system at a position in the processing unit indicated by each of the values of the remainder system to shuffle the predetermined data for every processing unit and, a data shuffling apparatus for the same.
