摘要： It is a purpose of the present invention to provide a video encoding apparatus and a video decoding apparatus which are capable of providing real-time processing having improved coding performance. A video encoding apparatus AA includes an inter-encoding predicted value generating unit 2 configured to receive, as input signals, an input image a, a local decoded value d acquired from an encoded block, prediction direction information e acquired from the encoded block, and interpolation filter initial control information b.

摘要： As the encoding mode, a moving-picture encoding apparatus includes an encoding mode that relies only on inference based on encoding information of a previously encoded unit block so as to encode a picture of a unit block. The encoding information in this encoding mode is imparted with secondary encoding information for improving the prediction performance, e.g., MV information. The MV information is produced by an MV-information producing unit 21 to which an input picture and MV information in a previously encoded MB are input. A locally-decoded picture producing unit 22 produces a locally-decoded picture (pixel value) of the previously encoded MB. As the secondary encoding information, a DC component of an orthogonal transformation result relative to a prediction error or a value equivalent to an average value of prediction errors can also be used.

摘要： A video encoder according to the present invention improves coding efficiency of a super high definition video by setting an area of MB size and optimally determining size of the area. A locally decoded image (a) is subjected to frequency analysis in a frequency analyzing unit. Based on the result, an area setting unit sets a local area in a picture to which the maximum MB size is applied. An area boundary correcting unit corrects an area boundary in accordance with a representative motion characteristic, and an N-value calculating unit determines the maximum MB size (N×N) of each area based on a result of encoding a neighboring picture. The area setting and the N-value calculation are performed step by step.

摘要： When packets reach from the 0 system and the 1 system, the packet selecting means 21 determines, based on the sequence numbers held in the packet output record register 22, whether or not the corresponding packet has passed, interrupts passing of the corresponding packet to the output side if passed, and allows the corresponding packet to pass to the output side if not passed. When the packet selecting means 21 selects a packet and allows the packet to pass to the output side, the packet output record register 22 holds the sequence number of the corresponding packet as a packet output record. Phase adjusting means that absorbs an average difference in delay for transmission between the systems may be provided at a stage before the packet selecting means 21.
