ABSTRACT:
A coding method codes a sequence of digitized images with a plurality of macro blocks in error-prone networks in which case the macro blocks in a section of the image are coded in a first intra-coding mode depending on predetermined criteria. In addition, the macro blocks in a section of the image are coded in a second intra-coding mode or in an inter-coding mode in which case in the inter-coding mode for the macro blocks, movement vectors are selected from the number of accessible reference images. The selection from the number of accessible reference images is limited in such a way that referencing takes place from image areas that were not subjected to the first intra-coding mode at a later stage.
