    • The invention relates to a method for determining a predicted image area for an image area, in which a temporal predictor for the image area is determined based on a reconstructed image that precedes said image, a local predictor for the image area is determined within a reconstructed image area of the image, a margin of error between the image area and the image area predicted based on the temporal and local predictors being minimized, and the predicted image area is determined by means of the local predictor using the reconstructed image area and by means of the temporal predictor using one of the preceding images. The invention further relates to a method for reconstructing a predicted image area. Also disclosed are an establishing device for carrying out the method for determining a predicted image area as well as a reconstructing device for carrying out the reconstruction method.

    • Header elements are coded by means of a code word table in order to compress data blocks for transmission with header information, whereby a code word is allocated to each of said header elements, or a transition between two serial header elements, which is transmitted instead of the actual header information. A current header information is predicted by using the code words for the corresponding header elements and the code word length selected to be inversely proportional to the probability of occurrence of a header element, determined by statistical evaluation of the header information from preceding data blocks and the code word table for coding the current or a subsequent data block arranged by means of the distribution for individual header elements obtained thus, such that a next most statistically-significant header element is assigned the next shortest code word.
