摘要： The present invention relates to, for example, 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 (5 8), from among the syntax elements of input image compression information, the frame/field flag is first encoded by a frame/field flag context model (91). When the macroblock to be processed is subjected to frame-based encoding, a frame-based context model (92), 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 (94) 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： It is an object of the present invention to provide a decoding apparatus with which the operation quantity and the number of memory accesses in motion prediction/compensation processing with respect to B picture can be reduced. The decoding apparatus decodes, by inverse-orthogonal transform and motion compensation, a compressed image information at least including intraframe, interframe forward predictive and interframe bi-directional predictive encoding images. The motion compensation processing is performed by using a first filter with respect to the interframe forward predictive encoding image, wherein interpolation processing of 1/2 pixel accuracy and interpolation processing of 1/4 pixel accuracy are performed by using the first filter having 8 taps and another filter having 8 taps, respectively, and motion compensation processing is performed by using a second filter having a fewer number of taps than the first filter, with respect to the interframe bi-directional predictive encoding image.

摘要： An encoding apparatus adds delay time information DTI indicating initial de-lay time i_d and delay time d of each group data to a position to be read prior to frame data by a decoding apparatus in the group data of encoding stream data DBI and transmits the same to the decoding apparatus 3. Namely, the encoding apparatus does not transmit initial offset delay time i_of to the decoding apparatus 3. The encoding apparatus starts to read and transmit the encoding stream data DBI from a transmission buffer at a predetermined bit rate R at timing designated by the initial offset delay time i_of.
