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.

摘要： A corresponding MB2 for the left sequence is determined from the parallax vector of a coding-object MB1 of the frame Bi for the right sequence. The motion vector {circle around (2)} of the corresponding MB2 is used as an origin of the search area for finding the motion vector of the coding-object MB1. As an alternative, the motion vector {circle around (3)} of MB3 adjacent to the coding-object MB1 is used as an origin of the search area for finding a motion vector of the coding-object MB1. As another alternative, the motion vector {circle around (2)} or {circle around (3)}, whichever is higher in utility evaluation, is used as an origin. As a result, both the search area and the circuit size for detecting a motion vector can be reduced. This configuration provides a stereo video data motion vector coding apparatus small in circuit size and capable of detecting a motion vector with high accuracy.

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. The inter-encoding predicted value generating unit 2 includes a filter control unit 21. The filter control unit 21 extracts the tap size N of the interpolation filter and the initial value c0(i,j) of the filter coefficient of the interpolation filter from the interpolation filter initial control information b, and uses the initial value c0(i,j) of the filter coefficient of the interpolation filter as the filter coefficient c(i,j) of the interpolation filter.

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.
