ABSTRACT:
Each of a plurality of pages of video data are shuffled, each of the pages being composed of a plurality of blocks of data, using a data memory having a memory capacity of one page. The one page data memory temporarily stores data in a current page. A data address generator generates an address of the data memory so that the data in the current page are written into the data memory in a first sequence and the written data are read out from the data memory in a second sequence which is different from the first sequence to thereby shuffle the data in the current page. The data address generator generates the address such that data in a block in the current page is read from a portion of the data memory indicated by the address generated by the data address generator, and such that data in a block in a next page is written into the portion of the data memory indicated by the address generated by the data address generator.
