Method for producing video coding and programme-product

A device for video coding for a current image represented by macroblocks and part of a data stream, the device comprising:

• a processor;
• and
• a machine-readable memory, the memory storing instructions that, when loaded and executed by the processor, cause the processor to:
• receive motion vectors for the macroblock of the current image based on one or more previously received reference images, wherein at least one previously received reference image is stored in an image memory;
• calculate a prediction image based on the received motion vectors, the prediction image representing predicted movement of the macroblocks of the reference image based on the received motion vectors;
• provide a prediction error matrix, indicating a prediction error after transformation by a transformer and quantization by a quantizer, the prediction error representing a subtraction result by subtracting the prediction image from the current image by a subtractor;
• convert the prediction error matrix by coefficient sampling into a series of symbols;
• perform context-adaptive arithmetic encoding of the symbols on the basis of symbol frequencies with an already-encoded symbol, the already-encoded symbol appearing immediately before a given symbol for which context-adaptive arithmetic encoding is performed, and
• form a bit stream by the context-adaptive arithmetic encoding of the symbols.
