Abstract
In a method for coding a video data stream of a video sequence consisting of image blocks, a motion estimate for each block by determining a motion vector for that individual image block. The motion vectors of adjacent blocks are checked for agreement with one another. The transformation coding of an image block to be coded is suppressed, if the motion vector for that image block best corresponds, as the result of the agreement check image vector of a preceding, already transformation-coded image block. In this way, a considerable savings of the required data rate for the transmission of the video data stream to the receiver is achieved, as is a considerable savings in computing expense for the execution of the transformation coding.
