1. A decoding apparatus, comprising:

  • circuitry configured to;

    set a first chroma quantization parameter (QP) included in a chroma QP range from 0 to 51 equal to a luma QP range, based on a parameter including a picture level chroma QP offset added to a luma QP; and

    inverse quantize quantization data that is decoded from a bit stream, based on the first chroma QP.
