Vorrichtung und Verfahren zur Datenmischung und -entmischung
摘要
To equalize the information content of image data prior to compression, a shuffling and deshuffling technique divides the video image into a multitude of image blocks, and selects a predetermined number of the image blocks from different spatial locations in the image, to form a succession of data sets representative of the video image information. The selection of the image representing blocks is such that the information content in each data set is similar to the information content in each other data set and similar to the average information content of the entire video image. <IMAGE>
