In a portable device connectable to a network system, an access right information acquisition unit acquires access right information of a computer resource assigned to a user temporarily registered to the network system from a computer which manages the computer resource in the network system. An access right information preservation unit preserves the access right information acquired by the access right information acquisition unit. A network access unit accesses the network system using the access right information preserved in the access right information preservation unit.

Portable device and a method for accessing a computer resource of a temporary registered user

By using program information, the amount of which to be transmitted is not fixed, and related information which is related to the expected amount of the main information, an area for recording main information is ensured in advance on a recording medium. This ensures a reliable recording of a program, the recording of which has already been reserved, without affecting any program which has already been recorded. In addition, even when a change occurs in related information before or after the start of recording information on the recording medium, an area assigned before the start of the recording can be changed corresponding to related information after the change.

Apparatus for recording data, method for recording data and television program receiver

In a computer resource assignment apparatus, a registration request processing section assigns a computer resource to a user in response to a temporary registration request from the user. A computer resource management section manages the computer resource assigned to the user of the temporary registration request by unit of each user.

Computer resource assignment of a temporary user from a computer pool of available identifiers

A reservation processing apparatus. A data receiving section receives broadcast data including mainview data and preview data. The preview data represents information of next mainview data. A preview data record section records the preview data received by the data receiving section. A reservation list management section extracts the information of next mainview data from the preview data and stores the information as a reservation list. A reservation item execution section records the next mainview data according to the reservation list when the data receiving section receives the next mainview data transmitted.

Reservation processing apparatus and method

An integrated network management and apparatus for managing devices connected to a network which have the same function. Control modules prepare local management tables by reading information regarding recordings made on respective recording media of the devices, and an integrated control module communicates with the control modules to prepare an integrated management table by reading the local management tables. The integrated management table enables the integrated control module to recognize a correlation between a recorded program and the control module, recording medium and recording position. The integrated control module also controls the control modules in the respective devices in an integrated manner using the integrated management table.

Apparatus and method for network integrated management

A navigation communication system in which a plurality of clients access information stored in a server via a network, having a personal information control section provided in the server and controls the personal information of the users of the clients which access the same information and a personal information display section provided in the client and displays the personal information controlled by the personal information control section, a selector for selecting one of the personal information displayed, and a communication application section for communicating with a client corresponding to the selected personal information.

Communication navigation system which easily finds person who is

A network manager, when a transmission is requested from any FA equipment under control by the network manager, sets a flag indicating a loop direction for transmission in a transmission frame and transmits the transmission frame to other stations, and when network controllers receive the transmission frame with a flag indicating the loop direction set therein, the network controllers check whether the loop through which the transmission frame was actually received is the same as that indicated by the flag in the received transmission frame or not, and if it is determined that the loop through which the transmission frame was actually received is different from that indicated by the flag above, the network controllers send the transmission frame including an error report indicating the loop direction to the network manager.

Communication control method in network system based on duplex loop

The multicast communication scheme which can enable a user to easily comprehend the multicast groups existing on the network, easily carry out an operation to join a desired multicast group, and easily specify a desired communication quality. At each user terminal, a virtual space with a plurality of regions defined therein in correspondence to a plurality of multicast groups is displayed on a screen, while an information indicating a range of each region in the virtual space is stored in correspondence to an address information for a corresponding multicast group. A desired position in the virtual space on the screen is specified by an input device, and joining/leaving to/from multicast groups is controlled by using the address information stored in correspondence to a region in the virtual space which contains the desired position. The display on the screen may include a plurality of zones defined within each region in correspondence to a plurality of different communication qualities, so that a communication quality of a multicast communication to be received can be controlled according to a zone within a region in the virtual space which contains the desired position.
