Method for replacing parts of a digitally coded picture, and device for carrying out the method

摘要

The method involves separately run length-coding each line of the image (11). The part of the image which replaces the replaceable, original part of the image line is run length-coded in such a way that the associated coding words occupy the same number of data units as the coding words of the original part of this image line. The replacement of the data for the run length coding words is performed in a memory device. The digitally coded image can be a sub-image displayed on the screen of a display device.
