Abstract:
The present invention relates to an entropy decoding method and to a decoding apparatus using same. The entropy decoding method according to the present invention comprises: a step of decoding a bin of a syntax element; and a step of acquiring information on the syntax element based on the decoded bin. In the step of decoding the bin, context-based decoding or bypass decoding is performed for each bin of the syntax element.

Claim (Index 11):
A method for image encoding performed by an encoding apparatus, the method comprising:\n deriving, by the encoding apparatus, a chroma intra prediction mode of a current block; determining, by the encoding apparatus, a value of an intra_chroma_pred_mode syntax element based on the derived chroma intra prediction mode; and encoding, by the encoding apparatus, bins of a bin string for the intra_chroma_pred_mode syntax element based on the value of the intra_chroma_pred_mode syntax element, wherein a first bin among the bin string for the intra_chroma_pred_mode syntax element is encoded based on regular coding using context information and remaining bins among the bin string for the intra_chroma_pred_mode syntax element are encoded based on bypass coding.
