摘要： A motion vector can be accurately detected in a video signal processing device that performs video signal processing with use of a plurality of processors. The video signal processing device includes motion vector detection units (121a, 121b) that detect motion vectors from an input video signal; a vector memory (122a, 122b) that stores information indicating the detected motion vectors; frame interpolation processing circuits (123a, 123b) that process video signals, the input video signal being divided into n (n being an integer greater than or equal to 2) regions, and processing of video signals corresponding to the regions being divided among the frame interpolation processing circuits (123a, 123b) and performed with use of the motion vector information stored in the vector memory (122a, 122b); and a screen synthesis unit (13) that generates an output video signal by synthesizing the processing results of the frame interpolation processing circuits (123a, 123b). The motion vector detection units (121a, 121b) detect motion vectors with respect to regions that include regions obtained by completely dividing the input video signal into two regions, and are larger than the obtained regions.

摘要： When a packet transfer equipment receives a packet, it extracts several types of information contained in the received packet such as the destination IP address and the destination port number and, using the extracted information as the key, inquires of a packet transfer method resolution server about the information related to the packet transfer method. The server keeps the correspondences between several types of information contained in the packet and one or more type of information related to the packet transfer method in the database and, in response to the inquiry from the packet transfer equipment, replies one or more type of information related to the packet transfer method. The packet transfer equipment rewrites several types of information such as the destination IP address and the destination port number according to one or more type of information obtained and transfers the received packet.

摘要： A DNS Proxy unit (A12a) holds the domain name of an encrypted communication target node in a CUG setting table (A125a), intercepts a name resolution request for a communication partner node output from an application (A11x) to a DNS server (B1a), determines by looking up the CUG setting table (A125a) whether the communication partner is an encrypted communication target node, and if the communication partner is an encrypted communication target node, registers the IP address of the name-resolved communication partner in an encrypted communication path setting table (A142a). A data packet sent from the application (A11x) to the IP address is intercepted by a data transmission/reception unit (A14a). A data packet to an IP address registered in the encrypted communication path setting table (A142a) is encrypted by a communication encryption unit (A141a) and transmitted to the communication partner. In this way, in executing encrypted communication with a plurality of communication partners by using a communication encryption function provided by an OS, setting of the encrypted communication target node can be done by using a domain name.
