摘要:
Upon receipt of a request to connect to an ad-hoc network from an external communication node, an address assigning unit obtains information on an IP address assigned to the external communication node. The address assigning unit determines whether the IP address is already used by any of communication nodes that are connected to the ad-hoc network based on network management information stored in a storage unit. The address assigning unit generates a new IP address that is used none of the communication nodes when the IP address is already used, and transmits the new IP address to the external communication node. The external communication node is assigned the new IP address, and connects to the ad-hoc network.

A communication scheme assigns address and determines the setting of address servers. In this scheme other communication devices are prohibited to transmit an address initialization request for a prescribed period of time since one communication device transmitted the address initialization request for an address managed by a control protocol, so that conflict of the initialization requests for the same address will not occur and the problem of assigning the address in overlap to the communication devices will not arise. Also, other communication devices are prohibited to transmit an address server detection request packet for a prescribed period of time since one communication device transmitted the address server detection request packet, so that the conflict on the network by a plurality of address server detection requests will not occur, and it is possible to determine the MAC address server uniquely.

According to a data display method, data having a program unit and instruction data for the program unit multiplexed on bit stream data is received. The program unit is extracted from the received data and is stored in a memory. The instruction data is extracted from the received data, and the program unit or part thereof specified by the instruction data is read from the memory and is executed. Then, the bit stream data and the execution result are displayed. This ensures smooth synchronization of reproduction of a bit stream with execution of an associated program and efficient use of resources.

A data transfer control device and a relay device which are suitable for use in the home network environment. For a case of controlling transfer of information data to a receiving node connected with a first physical network from a transmitting node connected with a second physical network, there is provided a data transfer control device connected with the second physical network which has: an establishing unit for establishing a channel in the second physical network for transmitting the information data; a reserving unit for reserving a communication path for transferring the information data transmitted through that channel to another data transfer control device belonging to the first physical network and/or the receiving node; and a commanding unit for commanding the transmitting node to transmit the information data through that channel, by using a protocol depending oh the second physical network.

A magnetic shielding door (10) opens and closes a gate (16) of a magnetic shielding room. Magnetic members (15) made of a magnetic material are aligned at intervals on walls of the magnetic shielding room. Magnetic shielding forming members (27) are disposed to correspond to the respective magnetic members (15) and are made of a magnetic body that forms a magnetic shielding in corporation with the magnetic members (15). A movable mechanism (28) moves the magnetic shielding forming members (27) at the door closing position at which the gate (16) is closed. The movable mechanism (28) moves the magnetic shielding forming members (27) between a join position at which the magnetic members (15) and the corresponding magnetic shielding forming members (27) are joined to each other and a spaced-apart position at which the magnetic members (15) and the corresponding magnetic shielding forming members (27) are spaced apart.

A magnetic shield structure having openings, the structure comprising a plurality of similar magnetic blind bodies 2, each blind body 2 having an imaginary blind core plane F and a plurality of magnetic material slats 1 being spaced from each other by a distance d required for magnetic shielding, each slat 1 intersecting the blind core plane F at a longitudinal central axis C thereof, the longitudinal central axes of the slats are oriented substantially in parallel to each other on the blind core plane F. The blind bodies 2a, 2b are coupled in a row by serially coupling each slat 1 in each blind body 2a to a corresponding slat 1 of adjacent blind body 2b through overlapping or abutting of slat terminal portions, whereby the blind core planes Fa, Fb of the blind bodies 2a, 2b are so coupled as to define a successive magnetic shield plane, and spaces d between adjacent slats 1 in each blind body 2a, 2b form openings in the magnetic shield structure. Preferably, three or more magnetic blind bodies 2 are coupled in a row so as to form a closed magnetic path. The blind bodies 2a, 2b may be stacked side by side in such a manner that the blind core plane Fa, Fb are parallel to each other and orientation of the slat central axes in each blind body 2a, 2b being selected so as to optimize attenuation of magnetic field across the magnetic shield structure.

摘要:
A relay device and a communication device capable of realizing the contents protection procedure between devices that are not connected to the same network are disclosed. A relay device and a communication device are so configured that between a device/service/sub-unit on the second network and a device on the first network which are a pair that is carrying out transmission or reception of contents to be protected, a device on the first network or a device/service/sub-unit on the second network can carry out the contents protection procedure while recognizing the target of the contents protection procedure as the relay device, so that there is no need for a device on the first network or a device/service/sub-unit on the second network to account for the other network that is connected via the relay device.
