摘要： PROBLEM TO BE SOLVED: To provide a method of replacing a shared key which can realize a key replacement rapidly and safely even by a device, such as a network home electric appliance, etc. in which calculating resources and memory resources, etc. are limited. SOLUTION: An external device 1 transmits a message based on an existing key replacement protocol, such as an IKE, etc. to a device 2 in a house through an HGW 3 before a cipher communication with the device 2 in the house. When the message for replacing a key is received from the external device 1, the HGW 3 performs a key replacing process with the external device 1 by proxy of the device 2 in the house. The HGW 3 distributes the shared key replaced from the external device 1 to the device 2 in the house. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To obtain the device capable of browsing by which a content of an image is easily grasped. SOLUTION: A frame of a video image is received in the STEP 3, two adjacent frames are compared in the STEP 4, and the result is detected as a degree of a change in the video image. Whether or not a scene change (SC) is in existence is discriminated based on the magnitude of a degree of change in the video image in the STEP 6. When the discrimination indicates the presence of SC, whether the degree of change in the video image is caused rapidly or slowly is checked in the STEP 7 so as to discriminate whether the SC whose presence is confirmed is a momentary SC or gradual SC. When the discrimination depicts the rapid SC, the point of discrimination time is detected as a start point of the period of the rapid SC and when the discrimination depicts the gradual SC, the point of discrimination time is detected as a start point of the period of the gradual SC. When the start point of the period of the gradual SC is detected, whether or not an end point of the period of the gradual SC is discriminated and the routine is returned to the STEP 6.

摘要： PURPOSE:To attain iris control corresponding to a change in a lighting state of all pattern when the iris is corrected to pick up an image in the back light state. CONSTITUTION:When a back light discrimination circuit 11 discriminates a back light state, a control signal generating circuit 12 outputs a control signal to an iris drive circuit 7 to allow the circuit 7 to implement iris control corresponding to an output of an in-area level detection circuit 5. When the control signal generating circuit 12 receives a signal from a timing signal 15, the circuit 12 outputs a control signal to the iris drive circuit 7 to allow the circuit 7 to implement the iris control corresponding to the entire pattern level detection circuit 4, then a field buffer 14 receives a signal from the timing signal generating circuit 15 and outputs the same image pickup signal as that of a preceding field. The back light state is discriminated based on the image pickup signal inputted in the iris state corresponding to the entire pattern level detection circuit 4.

摘要： PROBLEM TO BE SOLVED: To provide an outdoor access system capable of starting a communication with an indoor apparatus 201 at a desired timing from an outdoor apparatus 202. SOLUTION: An indoor apparatus 201 registers its own global IP (Internet Protocol) address and a port number in a server 205 (step 103), and periodically sends packets to a dummy address in order to maintain an NAPT (Network Address Port Translation) table of a router 203 (step S105). The router 203 periodically receives the packets destined to the dummy address from an indoor apparatus 201, thereby mainlining NAT (Network Address Translation) slots to the indoor apparatus 201 from the server 205. Upon receipt of a connection request from the outdoor apparatus 202 to the indoor apparatus 201, the server 205 changes the sending source to the dummy address to send packets of the connection request to the indoor apparatus 201 (step S109).

摘要： PROBLEM TO BE SOLVED: To transmit and receive the delete information of IP sec SA certainly in spite of a variety of mounting methods for maintaining ISAKMP SA in automatic key switching. SOLUTION: A transmitting side communication apparatus transmits a delete payload of the IP sec SA using the ISAKMP SA to meet transmission conditions, preferably, using all ISAKMP SA existing between communication apparatuses. A receiving side communication apparatus receives the delete payload by the ISAKMP SA to meet receiving conditions, preferably, by either of the ISAKMP SA existing between the communication apparatuses. As long as the IP sec SA established by using the ISAKMP SA exists, the ISAKMP SA is not deleted completely but maintained, and the sending and receiving of the delete payload is made possible at the ISAKMP SA.

摘要： PROBLEM TO BE SOLVED: To provide a radio communication system which can prevent the loss of a packet at hand over and perform packet transfer in a real time manner, even if the hand over is put into practice, and to provide a method of executing the hand over to be used in the radio communication system concerned. SOLUTION: A radio terminal 100 forecasts the No. of a packet at the time of executing the hand over and sends it to a base station 200(#1). The base station 200(#1) transfers the No. of a changeover packet to a switchboard 300. The switchboard 300 sends back packets addressed to the radio terminal 100 to the base station 200(#2) from the packet having the changeover packet No. in question. This way, the radio terminal 100 forecasts the No. of the packet to switch the base station, and informs the switchboard 300 of the No. in question.

摘要： PROBLEM TO BE SOLVED: To provide a filing system capable of effectively utilizing a free band. SOLUTION: A request reception part 601 requests registration of write data to a processing registration part 602. The processing registration part 602 stores the write data in a delay write buffer part 607 as a request storage phase, and in the case that a free area is present in a delay write buffer of the request storage phase, stores the write data further in the free area and attains the delay write buffer of a write phase. The write data stored in the delay write buffer of the write phase are actually written to a file server 102 by a write processing part 605.
