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 sharp/blurred frame mode classifying unit specifies a frame to be subjected to sharp or blurred process. A 3D video signal extracting unit extracts a predetermined area or predetermined macro block in the specified target frame, and a 3D FFT 15 frequency-converts it to acquire a coefficient string. An intersection coordinate calculating unit finds a non-perceptible high frequency coefficient based on a spatio-temporal visual property model for the coefficient string, and a coefficient cut processing unit cuts the non-perceptible high frequency coefficient for a frequency conversion coefficient of orthogonal conversion of a predictive error signal. The code amount of a video signal is largely reduced for a high frame rate video by the processings only at the encode side without deteriorating the picture quality.

摘要： There is provided an intra prediction system having high prediction performance and satisfactory encoding efficiency in a pattern image in which pixel value is periodically changed and a pattern image in which pixel value has a constant change tendency like gradation effect. A frequency component extraction unit allows a pixel value of an encoded MB to be made one-dimensional for one-dimensional orthogonal conversion. A frequency component-considering prediction value calculation unit receives, as inputs, a pixel value of an encoded adjacent MB and an alternating current frequency component output to create an orthogonal conversion coefficient. The orthogonal conversion coefficient then is subjected inverted orthogonal conversion (IDCT) to generate a prediction value p(i). A prediction direction determination unit selects and outputs a prediction value p′ (i) in a prediction direction having the highest encoding efficiency among a conventional prediction value calculation unit and a prediction value calculation unit according to the present invention.

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.
