The system control unit 301 also controls the data storage unit 303 to store the URL of the Internet site displayed by the Internet browser 302.

Next, using the Internet connection terminal 100 and the mobile terminal 101, an Internet site displayed on the mobile terminal 101 is displayed on the Internet connection terminal 100, and following this display, an operation of operating the Internet connection terminal 100 using the mobile terminal 101 is performed. The details will be explained with reference to the flowcharts of FIGS. 4 and 5.

In FIG. 5, the operation of the mobile terminal 101 is shown in a frame 500, and the operation of the Internet connection terminal 100 is shown in a frame 513. In the following explanation, the flow of operations in box 500 and the flow of operations in frame 513 will be explained in parallel, and the flow of operations of mobile terminal 101 and internet connection terminal 100, respectively, and the flow of operations of both terminals will be explained in parallel. At the same time, we will explain the relationship between In the following description, the mobile terminal 101 is taken as an example of a mobile phone, and the internet connection terminal 100 is taken as an example of a television having an internet connection function.

First, the user sets the type of TV to be used for browsing the Internet, which will be described later, on the mobile phone in advance by specifying the manufacturer and model number using the input unit 102 on a predetermined setting screen (step 501). ). Here, the data storage unit 303 stores input numbers such as model numbers, operations performed by the user, and signals and information to be transmitted in association with each other. Then, the control means 301 sets a command to be transmitted to the television by associating the input operation of the data storage unit with the information to be transmitted. Setting this command enables the mobile phone to send commands that can be recognized by the television.

The user turns on the television through a predetermined operation, and the television receives and reproduces the broadcast received from the digital broadcast receiving section 200 using the mechanism described above (step 514). Step 514 is a state when the user uses the television alone, and this state is defined as the normal mode of the television. A state where the power is on refers to a state where at least the main power is on.

The user performs an operation on the mobile phone to start displaying a predetermined Internet page. By this operation, the Internet site is displayed on the display unit 305 of the mobile phone as shown in the screen display 401, and the user can browse the Internet site (step 502).

Steps 501 and 502 are states when the user uses the mobile phone alone, and this state is the normal mode of the mobile phone.

Assume that the user attempts to view the Internet site on a television while viewing the Internet site. In this case, the user performs an operation using the input unit 102 to select the button 402 displayed on the display unit 305 of the mobile phone (step 503). By the above operation, the mobile phone enters a display switching mode, which is a state for switching the display of the Internet site to the television.

When the mobile phone enters the display switching mode, the system control unit 301 of the mobile phone transmits the URL of the Internet site being displayed to the television via the data transmission/reception unit 306 (step 504). Furthermore, the system control unit 301 controls the display unit 305 and the like to end the display of the Internet site on the mobile terminal after or at the same time as transmitting the URL. Furthermore, the mobile phone may be configured to transmit a URL and a signal instructing the television to display an Internet site.

The television receives the URL from the mobile phone via the data transmitter/receiver 210 (step 515), connects to the Internet site indicated by the URL according to the procedure described above, and displays the URL on the display 206 as shown in screen display 406. The Internet site is displayed (step 516). Through step 516, the television enters a state in which it accepts operations from a mobile phone, and this state is set as an external operation acceptance mode. Further, by the operation in step 516, the display on the television is switched from the content that was being displayed before to the content that corresponds to the URL received from the mobile phone.

On the other hand, in the mobile phone, after transmitting the URL, the system control unit 301 becomes configured to be able to operate the television, which will be described later, using some keys of the input unit 102, and this state is set as an operation switching mode. The display unit 305 displays a display explaining to the user the contents of the operation that can be performed by pressing the key, as shown in the screen display 404, for example (step 505).

Here, the configuration in which the television can be operated means that by pressing some keys on the input unit 102, data indicating an operation for the television is transmitted, which allows the type of television set in step 501 to be determined. Therefore, the data has the same content as the data transmitted by the type of television remote control set in step 501, for example. As a result, when the user attempts to perform an operation such as moving a selected item on an Internet site displayed on the television or determining a selected item, the screen display 404 key of the input unit 102 of the mobile phone is pressed. By pressing a key corresponding to the operation content indicated by , the mobile phone transmits information or a signal indicating the instruction for the operation to the television (step 506). By the operation in this step, the mobile phone functions as a remote control for the TV. Further, the operation of this step is performed under the control of the control 301, for example.

When the data transmitting/receiving unit 210 receives information or a signal indicating the operation instruction from the mobile phone, the television transmits the contents of the instruction to the screen display 406 that displays the Internet or the operation of the Internet browser 208 under the control of the system control unit 201. is reflected (step 517).

When the user attempts to return from viewing an Internet site on a television to viewing an Internet site on a mobile phone as described above, the user selects the button display 405 displayed within the display section 305 of the mobile phone. The user performs the following operation (step 507). As a result of this operation, the mobile phone transmits data indicating the end of Internet display to the television through communication via the data transmitting/receiving unit 306 (step 508). Furthermore, the system control unit 202 controls the display unit 206 and the like to end the display of the Internet site on the television after or at the same time as transmitting the URL.

The television, which has received the data through the data transmitter/receiver 210, stops displaying the Internet site (step 518). Furthermore, the URL of the Internet site that was last displayed on the television is transmitted to the mobile phone via the data transmitting/receiving unit 210 (step 519), and the television program that was being displayed before starting to display the Internet is displayed on the screen, for example. 403 (step 520). In step 520, the television returns to a state in which it operates by itself, and enters the normal mode. Also, in step 520, the television resumes displaying the content that was being displayed before receiving the URL from the mobile phone. Note that in step 520, the television may simply end displaying the Internet site. The user can reduce the effort required to end the display on the television.

Further, the mobile phone receives the URL of the Internet site that was last displayed on the television, accesses the Internet site of the URL, and displays the URL (step 510). This operation switches the display of the Internet site from the television to the mobile phone, so the mobile phone enters display switching mode. The operation of this step is performed under the control of the control unit 301, for example. Further, the operation of this step causes the display of the Internet site to be resumed on the mobile phone.

At this time, the system control unit 301 changes the functions assigned to some keys of the input unit 102 that were used to operate the TV from the mobile phone, and treats them as keys for operating a normal mobile phone (step 511). . Further, the screen display is switched from, for example, the screen display 404 to the screen display 401, and the user continues to browse the Internet site displayed as the screen display 401 (step 512). In step 512, the mobile phone returns to the state in which it operates as a standalone mobile phone, so the mobile phone enters the normal mode.

In this way, the URL of the Internet site to be viewed on the mobile terminal 101 is transmitted to the Internet connection terminal 100 by wireless communication, the Internet connection terminal 100 that receives the URL displays the Internet site, and the user further displays the Internet site. The mobile terminal 101 is used to operate the Internet connection terminal 100 as described above.

The mobile terminal 101 operates in a display switching mode in which the display is switched from a normal mode in which the mobile terminal 101 operates alone to the Internet connection terminal 100 by the user pressing a button once to switch the Internet display to the Internet connection terminal 100. , and then successively transitions to an operation switching mode in which the Internet connection terminal 100 is operated by the mobile terminal 101. Furthermore, when displaying the Internet on the mobile terminal 101 again, simply by pressing the button for viewing the Internet on the mobile terminal 101 once, the operation switching mode is exited, the display switching mode is entered, and the normal mode is entered. Perform a series of actions to return.

As a result, the user can display an Internet site on a larger screen by simple operations using only the mobile terminal 100, without having to perform any operations on the terminal on which the user wishes to display the Internet site, and furthermore, the user can continue using the mobile terminal 100. The user can use this to operate the terminal that newly displayed the Internet site, and the user can smoothly switch the display of the Internet site between different terminals.

Note that in the above-described embodiment, the screen display 406 displays the Internet site on the display unit 206 of the Internet connection terminal 101 in full-screen display, but the Internet site may be displayed on a portion of the screen.

In this embodiment, when an Internet site is viewed on the mobile terminal 101, a subject who performs communication via the Internet network and processing to output received information as a video connects the mobile terminal 101 to the Internet connection device. It will switch to 100. Therefore, for example, if the communication speed at which the Internet connection device 100 communicates via the Internet network is faster than the communication speed at which the mobile terminal 101 communicates via the network, the user may perform operations for browsing the Internet site. While using the mobile terminal 101, it is also possible to browse Internet sites through faster communication.

Furthermore, in this embodiment, examples of Internet connection terminals include a television device, a set box device, and a DLNA compatible server. When this embodiment is applied to these devices, the problems that occur under the conditions described below can be solved.

For example, these information processing devices such as televisions are often installed in living rooms and shared by multiple people. For this reason, it may be necessary to suddenly interrupt viewing using a display such as a television. Specifically, this is the case when multiple people are watching television, making it difficult for individuals to view Internet sites.

In this case, in order for the user to continue viewing the Internet site etc. on the mobile terminal 100, for example, the user can turn off the display screen of the Internet site on the TV, start the browser of the mobile phone with the communication function, and It is possible to continue viewing on a mobile phone with communication functions by inputting the displayed URL into the mobile phone. However, this method has a problem in that the operation requires a large number of steps.

On the other hand, according to the mobile terminal 101 and the Internet connection device 100 of this embodiment, for example, the above-mentioned problems are solved, and the main body of display and communication is not only switched from the mobile terminal 101 to the Internet connection device 100. , it becomes possible to easily perform the operation of switching from the Internet connection device 100 to a mobile terminal.

In this embodiment, an Internet site has been described as an example of content information, but the present embodiment is not limited to this, and information indicating other content such as a television program may be used. Furthermore, although a URL has been described as an example of identification information, the present invention is not limited to this. For example, the identification information may be information indicating a TV program channel.

Next, Example 2 will be explained. This embodiment describes a method for realizing the same operation as in Embodiment 1 by using infrared communication for communication used for sending and receiving URLs and instructions for various operations in the Internet connection terminal 100 and mobile terminal 101 of Embodiment 1. explain.

The present embodiment will be described below based on the drawings. Further, in the following, parts equivalent to those in the previous embodiment are given the same reference numerals, and their explanations are omitted to avoid duplication.

In the Internet connection terminal 100 of the second embodiment shown in FIG. 6, unlike the first embodiment shown in FIG. Data is sent and received using the infrared command communication format defined by the IrDA standard and infrared communication compliant with the IrDA standard.

In the mobile terminal 101 of the second embodiment shown in FIG. 7, unlike the first embodiment shown in FIG. Data is sent and received using this signal.

The operation of this embodiment will be described below with reference to the flowcharts of FIGS. 6, 7, and 8. In this embodiment, when a URL of an Internet site is transmitted from the mobile terminal 101 via infrared communication by a user operation while receiving and playing back a digital broadcast, the Internet connection terminal 100 displays the Internet site and displays the URL of the Internet site. Following the display, an operation of the Internet connection terminal 100 by the mobile terminal 101 is accepted through infrared communication.

FIG. 8 is a flowchart of FIG. 5 used in the first embodiment of the present invention with steps shown in thick frames added. Similar to FIG. 5, FIG. 8 shows the operation of the mobile terminal 101 in a frame 500, and the operation of the Internet connection terminal 100 in a frame 513. By explaining the flow of operations in frame 513 in parallel, the flow of each of the operations of the mobile terminal 101 and the Internet connection terminal 100 and the relationship between the flows of the operations of both terminals will be explained at the same time. In the following description, a mobile phone will be used as an example of the mobile terminal 101, and a television with an Internet connection function will be used as an example of the Internet connection terminal 100.

First, the user sets the type of TV to be used for browsing the Internet, which will be described later, on the mobile phone in advance by specifying the manufacturer and model number using the input unit 102 on a predetermined setting screen (step 501). ). In this embodiment, the command is, for example, a general-purpose infrared command that can be received and processed by a television. The general-purpose infrared command is, for example, a command transmitted in the form of a PPM (Pulse Position Modulation) signal. Further, the format of the general-purpose infrared command is determined by each manufacturer, for example, and is a format used for communication with the attached remote control.

The user turns on the television through a predetermined operation, and the television receives and reproduces the broadcast received from the digital broadcast receiving section 200 using the mechanism described above (step 514).

The user performs an operation on the mobile phone to start displaying a predetermined Internet page. By this operation, the Internet site is displayed on the display unit 305 of the mobile phone as shown in the screen display 401, and the user can browse the Internet site (step 502).

Assume that the user attempts to view the Internet site on a television while viewing the Internet site. In this case, the user performs an operation to select the button 402 displayed on the display section 305 of the mobile phone (step 503).

Through the above operation, the infrared transmitting/receiving unit 700 of the mobile phone instructs the television to start IrDA communication by transmitting an infrared command that can be recognized by the type of television set in step 501 (step 800). Upon receiving the infrared command, the television starts IrDA communication (step 801) and requests the mobile phone to establish an IrDA communication connection (step 802). On the other hand, immediately after transmitting the infrared command in step 800, the mobile phone prepares to start an IrDA connection, responds to the request from the television for connection of IrDA communication, and establishes an IrDA connection between the television and the mobile phone. A communication connection is established (step 803). Further, the system control unit 301 controls the display unit 305 and the like to end the display of the Internet site on the mobile terminal 101 after transmitting the URL or at the same time as transmitting the URL.

In response to the establishment of the IrDA communication connection, the system control unit 301 of the mobile phone transmits the URL of the Internet site being displayed to the television via the IrDA communication by the infrared transmitting and receiving unit 700 (step 504). ).

The television receives the URL from the mobile phone via the infrared transceiver 600 (step 515). Further, the television transmits data indicating that the URL has been successfully received to the mobile phone via IrDA communication by the infrared transmitting/receiving unit 600 (step 804). When the mobile phone receives data indicating that the URL has been successfully received (step 805), it disconnects IrDA communication by the infrared transmitting/receiving section 700 (step 806). As a result of the disconnection, the television also ends IrDA communication by the infrared transmitting/receiving section 600, and enters a state in which it can accept normal infrared commands from a remote controller (not shown) or the like. Furthermore, the Internet site indicated by the URL is connected according to the procedure described above, and the Internet site is displayed on the display section 206 as shown in the screen display 406 (step 516).

On the other hand, in the mobile phone, after transmitting the URL, the system control unit 301 uses some keys on the input unit 102 to configure the television, which will be described later, to be operable, and the display unit 305 displays, for example, a screen display 404. As shown in (step 505), a display is made to explain to the user the contents of the operations that can be performed by pressing the key. Here, the configuration in which the television can be operated means that, by pressing some keys on the input unit 102, an infrared transmitting and receiving unit transmits an infrared command to operate a television that can identify the type of television set in step 501. 700, and the infrared command has the same content as the infrared command transmitted by, for example, a remote controller (not shown) of the type of television set in step 501. As a result, when the user attempts to perform an operation such as moving a selection item or determining a selection item on the internnet site being displayed on the television, one of the keys on the input section 102 of the mobile phone can be By pressing a key corresponding to the operation content indicated by 404, an instruction for the operation is transmitted from the mobile phone to the television (step 506).

The television, which has received the operation instruction from the mobile phone, reflects the contents of the instruction on the screen display 406 that displays the Internet and the operation of the Internet browser 208 (step 517).

When the user attempts to return from viewing an Internet site on a television to viewing an Internet site on a mobile phone as described above, the user selects the button display 405 displayed within the display section 305 of the mobile phone. The user performs the following operation (step 507). By this operation, the mobile phone transmits an infrared command indicating the end of displaying the Internet to the television via the infrared transmitting/receiving section 700 (step 508).

Upon receiving the infrared command, the television stops displaying the Internet site (step 518). Further, the television starts IrDA communication and requests IrDA communication connection from the mobile phone (step 808). On the other hand, immediately after transmitting the infrared command in step 508, the mobile phone starts IrDA communication, receives a request from the television for IrDA communication connection, and establishes IrDA communication connection (step 809).

After the communication connection is established, the television transmits the URL of the Internet site that was last displayed on the television to the mobile phone via the infrared transmitter/receiver 600 (step 519). The mobile phone receives the URL (step 509), and transmits data indicating successful reception of the URL to the television via IrDA communication (step 810). The television receives the data (step 811), terminates IrDA communication by the infrared transmitting/receiving section 600, and enters a state in which it can accept normal infrared commands from a remote controller (not shown) or the like (step 812). Furthermore, the television displays the television program that was being displayed before starting to display the Internet, for example, as shown in screen display 403 (step 520).

On the other hand, the mobile phone that has received the URL of the Internet site that was last displayed on the television terminates IrDA communication (step 813), accesses the Internet site of the URL, and displays it (step 510). At this time, the system control unit 301 changes the functions assigned to some keys of the input unit 102 that were used to operate the TV from the mobile phone, and treats them as keys for operating a normal mobile phone (step 511). ). Further, the screen display is switched from, for example, the screen display 404 to the screen display 401, and the user continues to browse the Internet site displayed as the screen display 401 (step 512).

In this way, the URL of the Internet site to be viewed on the mobile terminal 101 is transmitted to the Internet connection terminal 100 by infrared communication, the Internet connection terminal 100 that receives the URL displays the Internet site, and the user further displays the Internet site. The mobile terminal 101 is used to operate the Internet connection terminal 100 as described above. Furthermore, when transmitting these URLs and operation instructions, the TV can be operated using a mobile phone while switching between communication using infrared commands received by the TV from a remote control or the like and communication using IrDA as described above.

As a result, the user can display an Internet site on a larger screen by simple operations using only the mobile terminal 100, without having to perform any operations on the terminal on which the user wishes to display the Internet site, and furthermore, the user can continue using the mobile terminal 100. The user can use this to operate the terminal that newly displayed the Internet site, and the user can smoothly switch the display of the Internet site between different terminals.

Note that in the configuration of this embodiment, IrDA communication is used when transmitting the URL, but the communication is not limited to IrDA communication, and other communication means may be used.

Furthermore, in this embodiment, a television device, a set box device, and a DLNA-compatible server are mentioned as examples of the Internet connection terminal 100, but if this embodiment is applied to these devices, problems will occur under the conditions described below. points can be resolved.

For example, with general-purpose infrared commands used in television devices, the types of commands that can be sent and received are limited, or the communication speed is limited. On the other hand, signals indicating URLs and operation information have a larger amount of information than signals sent and received simply to turn on and off the power with a remote control. Therefore, when using general-purpose infrared commands, there is a problem that URLs and operation information cannot be sent and received between the mobile terminal and the information processing device, or even if it is possible, it takes time to send and receive information.

On the other hand, when performing IrDA-compliant communication, it is necessary to establish communication between the mobile terminal 101 and the Internet connection terminal 100 in order to send and receive information. Therefore, if communication is not switched from general-purpose commands to IrDA, it is necessary to always put the information processing device in a state of waiting for IrDA communication. If the connection is always established, a problem arises in that the Internet connection terminal 100 cannot perform infrared communication with other devices.

In contrast, in this embodiment, communication is switched using a general-purpose infrared command as a trigger, so it is possible to eliminate the above-mentioned problems and improve usability.

Although this embodiment has been described using IrDA communication as an example, it is also possible to use short-range communication such as Bluetooth communication, wireless communication such as wireless LAN, and sound wave communication. This embodiment is particularly useful when communicating using a communication method that requires a communication link to be established in order to send and receive information.

In this embodiment, an Internet site has been described as an example of content information, but the present embodiment is not limited to this, and information indicating other content such as a television program may be used. Furthermore, although a URL has been described as an example of identification information, the present invention is not limited to this. For example, the identification information may be information indicating a TV program channel.

Next, Example 3 will be explained. In this embodiment, when the Internet connection terminal 100 and the mobile terminal 101 of the first embodiment transmit and receive URLs and instructions for various operations, the mobile terminal 101 not only displays the Internet site indicated by the URL, but also displays the Internet site indicated by the URL. A method for realizing the operation of transferring the Internet site display state from the mobile terminal 101 to the Internet connection device 100 will be explained.

Here, the displaying state refers to, for example, a state in which the mobile terminal 101 is displaying a screen after login for an Internet site that requires authentication. Furthermore, the display state refers to, for example, the display state after a change in an Internet site where the display state of the content dynamically changes while the URL remains unchanged.

Information indicating the display state includes, for example, information indicating a history of user operations that have affected the display on the display unit 305. The information indicating the display state may include information that is not included in the URL but affects the display on the display screen 305 when browsing the Internet site. Further, the information indicating the display state may be information indicating character encoding such as Shift-JIS, EUC, or UTF-8. Furthermore, for example, a cookie may be used as information indicating the display state. Information indicating the display state is information indicating the position of the pointer, the position of the scroll bar, etc. displayed on the display unit 305 when the display is switched when displaying an Internet site on the mobile terminal 101. But that's fine. Further, the position of the pointer or the like may be information indicating the relative position of the pointer on the display screen. As a result, even if the sizes of the display areas of the mobile terminal 101 and the Internet connection terminal 100 are different, their relative positions can be reproduced on the Internet connection terminal 100.

The present embodiment will be described below based on the drawings. In this description, an example will be described in which an Internet site that requires authentication processing is taken over from the mobile terminal 101 to the Internet connection terminal 100. Further, in the following, parts equivalent to those in the previous embodiment are given the same reference numerals, and their explanations are omitted to avoid duplication.

FIG. 9 shows an example of data components and contents of an operation history 900 of user operations on the Internet site recorded by the mobile terminal 101 when the user browses an Internet site that requires authentication processing in this embodiment. Then, the mobile terminal 101 stores the operation history 900 in the data storage unit 303.

The information included in this operation history 900 includes, for example, character strings entered in text boxes, information indicating buttons and icons clicked on Internet sites, and information indicating contents selected on list boxes. . Further, the information included in the operation history 900 may include information indicating a URL displayed as a result of such an operation.

FIG. 10 shows data of an operation history 1000 of user operations on the Internet content recorded by the mobile terminal 101 when the user views the Internet content whose contents change dynamically without changing the URL in this embodiment. An example of components and contents is shown, and the mobile terminal 101 stores the operation history 1000 in the data storage unit 303. The operation history 1000 includes, for example, information indicating the position of the clicked coordinates.

FIG. 11 shows transmission data 1100 that the mobile terminal 101 transmits to the Internet connection terminal 100 in this embodiment, and the transmission data 1100 includes header data 1101 in which data length and data type identification information are described. , an Internet site URL 1102, and an operation history 900.

The operation of this embodiment will be described below with reference to the flowcharts of FIGS. 9, 10, 11, and 12. In the present embodiment, the mobile terminal 101 is configured to detect the Internet site that the user browses, for example, when the Internet site that the user browses is an Internet site that requires authentication processing, Internet content whose contents change dynamically without changing the URL, etc. An operation history 900 of user operations on Internet sites is recorded. Furthermore, in the same manner as in the first embodiment, when transmitting the URL of an Internet site to the Internet connection terminal 100, the mobile terminal 101 transmits transmission data 1100 consisting of the operation history 900 in addition to the URL. do. Further, by receiving the transmission data 1100, the Internet connection terminal 100 accesses the Internet site indicated by the URL, performs the same operation as the user operation indicated by the operation history 900 on the displayed Internet site, and performs the same operation as the user operation indicated by the operation history 900. It displays the Internet site in a state where the operation has been completed.

FIG. 12 is a flowchart of FIG. 5 used in the first embodiment of the present invention, with steps shown in thick frames added. Similar to FIG. 5, FIG. 12 shows the operation of the mobile terminal 101 in a frame 500, and the operation of the Internet connection terminal 100 in a frame 513. The flow of operations within frame 513 will be explained in parallel. That is, the flow of the respective operations of the mobile terminal 101 and the Internet connection terminal 100 and the relationship between the flows of the operations of both terminals will be explained at the same time. Further, in the following description, the mobile terminal 101 is taken as an example of a mobile phone, and the internet connection terminal 100 is taken as an example of a television having an internet connection function.

In this embodiment, while the user is browsing the Internet site in step 502, the mobile phone records the operation history 900 and the operation history 1000 each time the user performs an operation such as selection or input on the Internet site. The information is recorded in the data storage unit 209 (step 1201).

Note that at this time, the mobile phone does not need to record the operation history 900 and the operation history 1000 for all Internet sites visited by the user; for example, it is not necessary for the mobile phone to record the operation history 900 and operation history 1000 for all Internet sites that the user has viewed. , the Internet site is dynamically generated using a function such as ASP (Active Server Pages), or the document structure information of the displayed Internet site contains interactive content such as so-called FLASH (registered trademark). In some cases, the operation history 900 and the operation history 1000 may be recorded only for these Internet sites. When an Internet site includes FLASH or ASP content, it is defined by a tag in its source file, so a mobile phone can determine the type of site based on this tag.

Further, even if the Internet site is a dynamically generated Internet site, it is not necessary to store all the operation history in the operation history 1100. Among the operation histories, a configuration may be adopted in which a history related to operations that change the display is recorded. For example, if the Internet site includes dynamic FLASH content, the operation history may be configured to record operations such as clicks and character string inputs performed on the dynamic content.

Next, in this embodiment, when the user attempts to view the Internet site on the television in step 503 and performs an operation to select a button corresponding to the button display 402 displayed on the display section 305 of the mobile phone, The mobile phone configures transmission data 1100 that includes the URL 1102 of the Internet site that is the starting point for recording the operation history 900 or 1000, the operation history 900 or 1000, and further adds header data 1101. and transmits the transmission data 1100 to the television. Furthermore, after transmitting the URL, the system control unit 301 controls the display unit 305 and the like to end the display of the Internet site on the mobile terminal.

On the other hand, when the television receives the transmission data 1100 (step 1203), it accesses the Internet site of the URL 1102, performs the operation indicated in the operation history 900 or the operation history 1000 on the Internet site, and executes the operation. The Internet site after visiting is displayed (step 1204).

Note that in steps 509 and 519, the same method as described above is used when transmitting a URL from the television to the mobile phone and returning the terminal that accesses and displays the Internet site to the mobile phone.

In this way, if the Internet site that a user views on a mobile phone is an Internet site that requires authentication processing, or is Internet content whose content changes dynamically without changing the URL, the TV can save data. In the section 209, an operation history 900 and an operation history 1000 of user operations on the Internet site are recorded. Further, the television transmits transmission data 1100 that includes the URL of the Internet site from which the operation history 900 and the operation history 1000 are recorded, and the operation history 900 and the operation history 1000. Further, the television, which has received the transmission data 1100, accesses the Internet site indicated by the URL, performs the operation indicated by the operation history 900 and the operation history 1000 on the Internet site, and the Internet site in a state where the operation is completed. will be displayed.

As a result, when users switch access to the same Internet site between different terminals, they can check whether the Internet site they are viewing requires authentication processing or whether the content can be changed dynamically without changing the URL. Even in the case of changing Internet content, access can be smoothly switched without having to perform authentication processing or content operations again for a terminal newly accessing an Internet site.

Furthermore, when transmitting a URL from a mobile phone to an information processing device such as a television without transmitting any display information, the information processing device must ensure that the Internet site indicated by the URL does not affect the display in any way. It will be displayed in a state where no operation is being performed. Therefore, the more complex the structure of the Internet site, the more operations are required from simply sending the displayed URL to reflecting the operations on the mobile phone. According to the example mobile terminal 101 and internet connection terminal 100, it is possible to reduce the effort involved in operating them.

Each embodiment has been described above. Instead of the mobile terminal 101, other information processing terminals can communicate via the Internet and smoothly switch access between a plurality of terminals.
