<p>A video encoding method comprises: a conversion/quantization step that further comprises processing to convert a video signal of a space domain into a coefficient of a frequency domain for each of second processing units, one or more of which is contained in a first processing unit, and processing to quantize the coefficient of the frequency domain; and an arithmetic encoding step (S704) for arithmetically encoding a brightness CBF flag, which indicates whether a quantization coefficient is contained within the second processing unit upon which the conversion/quantization step was executed. In the arithmetic encoding step, a probability table to be used in the arithmetic encoding is determined (S702, S703), in accordance with whether the sizes of the first and second processing units are the same, and whether the size of the second processing unit is a prescribed maximum size (S701).</p> |
