Abstract:
A process for storing digital video data of an image, comprising the steps of:the image being chopped into a plurality of image blocks (h, v), wherein: each block of said plurality of image blocks (h, v) consisting of v lines of h pixels; and a set of image blocks from said plurality of image blocks constituting a row over an image width; the digital video data being stored successively as the plurality of image blocks in an order corresponding to a television type scanning where the plurality of image blocks are stored in successive pages of a dynamic random access memory (DRAM) used for reading at least one image block (H, V) consisting of V lines of H pixels, wherein, when considering positions of the plurality of image blocks (h, v) of the image and of the successive pages containing the plurality of image blocks (h, v), an horizontal shift D corresponding to an amount of the plurality of blocks (h, v), of a boundary of a page from the successive pages that corresponds to a row I of the image in respect to a boundary of a page from the successive pages corresponding to a next row of the image, which is implemented by leaving at least one memory space unused when storing the digital video data, so that the shift (D) is equal or greater than the maximum number of blocks (BM) minus 1 over which the at least one block (H, V) can be horizontally distributed.
