Abstract: A portable information processor wherein a menu to be easily used by a user is displayed on a relatively small screen. The portable information processor is provided with an installation section (12) for installing a program; a category information acquiring section (13) which acquires category information displaying a category of a new program upon further installation of the new program; and a category judging section (15) which compares the category of the new program indicated by the category information acquired by the category information acquiring section (13) with categories of a plurality of existing programs and judges whether the category of the new program overlaps any of the categories of the existing programs upon installation of the new program.

Abstract: A surveillance system having surveillance terminals and a surveillance center is configured to perform effective hazard alert signaling, depending on the hazard type. The surveillance system comprises a plurality of surveillance terminals, which are connected to the surveillance center by a network, carries out hazard and alert signaling. One surveillance terminal detects a hazard and sends a hazard information signal reporting what hazard has just been detected to the surveillance center. The surveillance center receives the hazard information signal, identifies what type of hazard source and the surveillance terminal that sent the hazard information signal, selects surveillance terminals to be alerted to the hazard from among the plurality of surveillance terminals, depending on the identified type of the hazard source and its locality, and sends a hazard alert signal to the selected surveillance terminals.

Abstract: A gateway realizes a connection between a network where HAVi devices are hooked up and another network in accordance with a Play-and-Plug spec. (e.g. the internet protocol (IP)) other than the HAVi spec. An HAVi plug-in detector detects a plug-in of a device to the HAVi network. A virtual device functions as a gateway for accessing from a device plugged-in the IP network to the device plugged-in the HAVi network. A virtual device controller provides the virtual device with an IP identifier for accessing to the virtual device from the IP network, and turns the virtual device to a standby status waiting for connection. A pseudo address generator generates a pseudo address for the virtual device to communicate with the device in the HAVi network, and provides the virtual device with the pseudo address. An address-correspondence-controller controls the correspondence between an HAVi address and the IP identifier both provided to the virtual device.

Abstract: The present invention provides a surveillance system, surveillance terminals, and a surveillance center, the surveillance system being configured to perform effective hazard alert signaling, depending on the hazard type, and a hazard and alert signaling method. The surveillance system of the invention where a plurality of surveillance terminals are connected to the surveillance center by a network carries out hazard and alert signaling. One surveillance terminal detects a hazard and sends a hazard information signal reporting what hazard has just been detected to the surveillance center.

Abstract: There is disclosed a system including an access right setting apparatus and manager terminal in which a user having an access to a resource of a network limited issues a request, and thereby an access right can easily be set, and the user who desires to access the resource describes set contents of the access right, such as the resource, time, and access content, in access request information 303, and transmits the information to an access right setting apparatus 100 for managing the access right in the system. The received access request information 303 is transferred to a manager of the resource by access request information transfer means 102, and the manager simply confirms a request content and makes judgment of approval, so that the access right setting apparatus 100 automatically sets the access right.
