Method for producing video coding and programme-product

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

• receiving motion vectors for a respective macroblock of the current image based on at least one previously received reference image stored in an image memory;
• calculating 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;
• providing 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;
• converting the prediction error matrix by coefficient sampling into a series of symbols;
• performing context-adaptive arithmetic encoding of the symbols on the basis of symbol frequencies with an already-encoded symbol appearing immediately before a given symbol for which context-adaptive arithmetic encoding is performed;
• and
• forming a bit stream using the context-adaptive arithmetic encoding of the symbols.
