Method for entropy-encoding slice segment and apparatus therefor, and method for entropy-decoding slice segment and apparatus therefor

摘要

The present invention relates to entropy encoding and entropy decoding for encoding and decoding a video signal. The method for entropy-decoding a video signal comprises the steps of: determining a bin string and a bin index for the maximum encoding unit obtained from a bit stream; when determining the value of a syntax element by comparing the presently obtained bin string with the bin strings to be assigned to the syntax element in the bin index, if the syntax element is the last one in the last maximum encoding unit, and a subordinate slice segment can be included in the picture including the maximum encoding unit, storing the context parameters for the maximum encoding unit; and decoding the symbols of the maximum encoding unit by using the value of the previously determined syntax element.
