ABSTRACT:
A method for replacing parts of a digitally coded picture (11) is proposed. The digitally coded picture (11) may correspond to a sub-picture which is displayed on the screen of a television set (10). In the method, each line of the picture (11) is run length-coded. The replaceable parts of a line of the picture are run length-coded separately. The part which replaces the replaceable, original part of a line of the picture (11) is run length-coded in such a way that it has the same number of data units (data bytes) as the original part of this line of the picture (11). The replacement of the data for the run length coding words is carried out in a memory device (51). The replacement is possible in a simple manner by virtue of the fact that the original part of a line of the picture and the new part of the line of the picture have the same number of data units. Moreover, a device for carrying out the method is also proposed.
