摘要:
An object of the present invention is to provide network devices and a network device control method which enable control network devices connected to an IP network, AV devices connected over 1394IF through gateway devices from the IP network, and home devices connected to ECHONET to be controlled without distinction among them. To achieve this object, a network device to serve as a controller comprises a controller application that detects a service of a target network device, using a message complying with an information exchange protocol common to the network, collects information such as an access method for the service, a function name, and parameters, and controls the network device upon request, and an information exchange protocol processing part that exchanges messages according to a protocol common to the network devices. The network device targeted for control comprises service that provides information for the controlling network device to perform control to the controller, and the information exchange protocol processing part.
摘要:
An authentication information and a verification information are previously generated and the authentication information is stored to an authentication data generating apparatus, while the verification information is stored to a gateway. When a controller tries to make communication With a customer premises apparatus, the authentication data generating apparatus connected to the controller generates an authentication data using the authentication information and the gateway verifies the authentication data using the verification information. Moreover, the gateway restricts, when connected to the authentication data generating apparatus, the communication between the controller located in the outside of customer premises and the customer premises apparatus. Moreover, the gateway changes, while connected to the authentication data generating apparatus, an address of the customer premises apparatus and stores the changed address to the authentication data generating apparatus. The address of the customer premises apparatus is not informed to the controller provided in the outside of customer premises. Consequently, a system for safely controlling the customer premises apparatus from the outside of customer premises with the controller without bringing this controller into the customer premises to register a controller identification information to the gateway can be provided.

Information terminal and information sharing method are provided which consider survival time of contents at a transmission destination and propagate the contents widely so as to be suitable for contents sharing. In the information terminal and information sharing method, contents allotted with survival time is received, the survival time allotted to the contents is changed, contents allotted with the changed survival time is transmitted to a different information terminal, and the contents is deleted after the changed survival time has expired.

摘要:
When conference conditions are set by a conference sponsor, a conference sponsor agent inquires of schedule management agents of requested attendants about available time within a range of set dates, determines an optimum conference schedule on the basis of the available time of the individual requested attendants, sends to the conference sponsor the conference schedule for confirmation thereof, and sends a conference notification to the requested attendants. In order to permit an input value set by a user to have a range in accordance with the kind of parameter requiring the input value and conditions at that time, an input value acquiring element acquires an input value of a parameter necessary for a processing realized by an application element, the input value being set by the user by an input element. An allowable value determining element determines an allowable value to be added to the input value on the basis of information supplied from the application element and corresponding to the kind of the parameter and conditions at that time, and an allowable value adding element determines a different input value from the acquired input value by adding the allowable value to the acquired input value and delivers the acquired input value and the thus determined different input value, as input values of the parameter, to the application element.
摘要:
A user interface application for an embedded device has a GUI-component general-purpose-structured-data generation section, a GUI-screen edition section, and a GUI-program generation section. The GUI-screen edition section provides to a user a means for creating a GUI screen by using a GUI component represented by the GUI-component general-purpose structured data generated by the GUI-component general-purpose-data generation section to generate, based on the GUI screen created by the user, GUI-screen general-purpose structured data in which any programming language can be used. The GUI-program generation section uses GUI-screen general-purpose structured data generated by the GUI-screen edition section and a program executable in a target device to generate a GUI application executable in the target device. The thus-configured present invention provides a technique for supporting development of a user interface application for an embedded device more easily than with conventional techniques.
