摘要： An encoding apparatus and an encoding method, a decoding apparatus and a decoding method, a recording medium, and a program suitable for encoding image signals with a higher compression ratio for transmission or accumulation. In an arithmetic coding section, from among the syntax elements of input image compression information, the frame/field flag is first encoded by a frame/field flag context model. When the macroblock to be processed is subjected to frame-based encoding, a frame-based context model, specified in the current H.26L standard, is applied. On the other hand, when the macroblock to be processed is subjected to field-based encoding, a field-based context model is applied for the syntax elements described below. The present invention is applied to an encoder for encoding image information and a decoder for decoding image information.

摘要： An image decoding method is for decoding a bit stream in an image decoding apparatus. The method includes receiving the bit stream and a weight parameter that is added to a luma quantization parameter by an addition operation. The method also includes decoding, in a decoding unit in the image decoding apparatus, the bit stream and generating a chroma component of quantized coefficients. In addition, the method includes performing, in a dequantization unit in the image decoding apparatus, dequantization on the chroma component of quantized coefficients using the chroma quantization parameter calculated on the basis of a luma quantization parameter weighted by the weight parameter.
