摘要： In a picture information encoding apparatus that outputs picture compression information according to a picture encoding system such as MPEG4/AVC, when it is determined whether the mode of a predetermined block is a skip mode or a spatial direct mode, moving vector information and so forth for all of predetermined adjacent blocks needs to have been computed. However, when each block is processed in parallel to speed up the entire processes, moving vector information and so forth of the predetermined adjacent blocks may not be always obtained. In this case, moving vector information and so forth of neighbor blocks instead of adjacent blocks are pseudo-used to determine the mode of the block without need to wait until moving vector information and so forth of adjacent blocks have been computed.

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.

摘要： The present invention is directed to an image information encoding apparatus, used in receiving compressed image information through network media when processing of such compressed image information is performed on storage media. A picture sorting buffer delivers information of picture type of frame Picture_type to a picture type discrimination unit. The picture type discrimination unit transmits command to a motion prediction/compensation unit on the basis of that information. The motion prediction/compensation unit generates predictive picture by using filter coefficients having the number of taps lesser than that of P picture with respect to B picture for which operation quantity and the number of memory accesses are required to more degree as compared to P picture on the basis of that command.
