Abstract: A hypertext displaying apparatus in which when a link destination indicated in stored data is designated, a processing section instructs a transmission/reception section to download hypertext data at the link destination. Additionally, the processing section instructs a history storage section to register an identifier of the currently-displayed stored data. If a user indicates a “previous content” instruction, the processing section reads from a stored information storage section the stored data corresponding to the identifier registered in the history information storage section, so that the stored data is displayed on a screen.

Abstract: A terminal-side communications control unit makes a request to a server for retrieving an instruction file that describes an instruction for transmitting transmission data. The server transmits the instruction file in response to the request for retrieving the instruction file. On receiving the instruction file, the terminal-side communications control unit causes an application executing unit to execute an application, and also forwards the instruction file to a transmission data generating unit. On receiving the instruction file, the transmission data generating part refers to the instruction file to generate, from generated data stored in a generated data storage unit, transmission data to be transmitted to the server.

Abstract: A mobile communication device that flexibly supports various services which utilize both Internet communications and short-distance wireless communications. An instruction data receiving section receives instruction data indicating a protocol in which a set of data exchanges are to be performed. An instruction data analysis section analyzes the received instruction data, and controls a reception switching section and a transmission switching section based on a result of the analysis. The reception switching section receives data from either an Internet reception section or a short-distance wireless reception section under the control of the instruction data analysis section. The transmission switching section outputs data to either an Internet transmission section or a short-distance wireless transmission section under the control of the instruction data analysis section.

Abstract: In a mobile communication terminal device that obtains data including text or an image from an external server through a digital network, a display displays display data DD generated based on data in a first storage unit. A plurality of display modes are predetermined in a display mode switching unit. When instructed by a user while the display data is displayed on the display, the display mode switching unit switches the display mode according to a predetermined order. A display data generator generates the display data DD according to the next display mode. The display displays the display data DD generated by the display data generator. It is thus possible to provide a mobile communication terminal device capable of displaying data while switching among a plurality of display modes (character sets or image display forms) through simpler operation.

Abstract: In a communications terminal 3, a CPU 32 retrieves start-up data 112 from a server 1 using a Web browser 311, which is stored in a storage device 31. The CPU 32 performs data authentication with respect to authentication type data 1123 included in the start-up data 112. Then, when the authentication is succeeded, the CPU 32 follows the authentication type data 1123 so as to determine which authentication mode is to be used for authenticating the application data. In this manner, the authentication mode for authenticating the application data can be easily changed.

Abstract: There is provided a message delivery system which does not generate the lack of the message, by making possible to issue an instruction to the server unit from the client system to process a message, which is received by the client system, at a timing when the client system has completed to receive the message as the application, and then performing the message process on the server unit side in compliance with the instruction.

Abstract: A mobile terminal is provided which can obtain an image from a server and change the size of the image so as to use the image as a background image. An image obtaining unit obtains an image from a server. An over-size decision unit decides whether the entirety of the image obtained by the image obtaining unit can be displayed within the display area in a screen. When the over-size decision unit provides a negative decision, an image resizing unit changes the size of the image obtained by the image obtaining unit so that it can be displayed within the display area in the screen.

Abstract: An information processor that can exchange information in real time between particular users by using an email system, and that can display a mail message received from a non-particular user even when the information is being exchanged. The information processor 1 includes a mail message sending section 101 for sending the mail message, a mail message receiving section 102 for receiving the mail message, a display section 104 for displaying the mail message, and a control section 105 for controlling switching between a particular mail message display mode and a non-particular mail message display mode. When returning to the particular mail message display mode after switching to the non-particular mail message display mode from the particular mail message display mode, the control section 105 causes the display section 104 to redisplay the contents displayed at the time of switching.

Abstract: Command data 111 includes an address of terminal data 112 to be received. A data processor 100 first verifies a signature applied to the received command data 111, and then receives the terminal data 112 specified by the command data 111. Thus received terminal data is used for controlling the data processor 100 such as screen display. At this time, the received data may be segmented into a protected data region and an unprotected data region, and any data type included in the unprotected data region may be listed as an unprotection list. If listed, the unprotection list may be arranged in the protected data region. Alternatively, a signer certificate may indicate, by type, what data is signable by its signer, and at the time of data reception, determination may be made whether the signer has an authorization for signing the data classified under the type.

Abstract: An information terminal device 10 is connected to a server 1 storing instruction data 200. For the received instruction data 200, a determining unit 104 determines the corresponding application. An analyzing unit 105 analyzes the instruction data 200. An operation control unit 106 extracts message data from the instruction data 200. An application executing unit 107 operates based on the instruction data and the above application. A display unit 19 displays a message represented by the message data on a screen based on the execution of the application. With an execution checking unit further provided, it is possible to determine whether the application is to be executed based on the message data.

Abstract: A hypertext displaying apparatus is provided. When a link destination indicated in stored data is designated, a processing section 104 instructs a transmission/reception section 103 to download hypertext data at the link destination, and instructs a history storage section 110 to register an identifier ID of the currently-displayed stored data. If a user gives a “previous content” instruction, the processing section 104 reads from a stored information storage section 111 the stored data corresponding to the identifier ID registered in the history information storage section 110, so that the stored data is displayed on a screen.
