Description

The present invention relates to a display device.

Mobile phones that can access internet sites and television programs are becoming widespread. Meanwhile, televisions that can connect to networks are also becoming more common. In this context, technologies are being considered that allow users to conveniently view the same content on their televisions as they view it on their mobile phones, as well as technologies that allow mobile phones to be used as remote controls to operate televisions.

For example, Patent Document 1 discloses a mobile phone equipped with a broadcast receiving function that transmits the viewing history of viewed broadcast programs and playback instruction signals to a video playback device. With this mobile phone, it is possible to watch a program that you watched while out again on a large screen after returning home, or to watch part of a program in your spare time while out and then watch the rest, the parts before and after that, or the entire program from start to finish on an indoor recording and playback device after returning home.

Patent document 2 also describes a system including a mobile phone, an information processing device, and a display device in which, when email data with URL information is received by the mobile phone, the email data is transferred to the information processing device via wireless communication, the email data transferred from the mobile phone via wireless communication is received by the information processing device and displayed on the display device, and when an operation is performed on the URL information in the email data displayed on the display device, the system accesses a server device connected to a wireless communication network different from the wireless communication network mentioned above based on the URL information, and displays the obtained information on the display device.

Patent document 3 also describes using a communication terminal device that normally has a different function as a remote control to remotely operate another communication terminal device.

Patent Document 4 also describes a videoconferencing system that uses a mobile phone connected to a videoconferencing server via the Internet and capable of sending and receiving information with the videoconferencing server, and a display device that is connected to the mobile phone via a communications function and can display the information, to control devices connected to the videoconferencing server via a network. The videoconferencing system is characterized by having information display means that displays a first videophone screen that displays the information in text on a first display of the mobile phone, and a second videophone screen that displays image information contained in the information on a second display of the display device. Patent Document 4 also describes a system that uses a mobile phone to remotely control a surveillance camera and displays the images on a PC display screen.

JP 2006-286855 A (Abstract) JP 2005-135346 A (Abstract) JP 2006-338406 A (paragraph number 0152) JP 2007-74265 A (Claim 7, paragraph 0068)

The mobile terminal etc. of Patent Document 1 is configured to display a list of programs that have been previously viewed (Figure 7) and play a selected program from that list on a video playback device, in order to meet requests such as wanting to watch a program that was viewed while out again on a large screen after returning home, or watching part of a program in your spare time while out and then watching the rest, the parts before and after that, or the entire program from start to finish on an indoor recording and playback device after returning home (paragraph 0006).

However, there is a demand for the ability to take over viewing of content currently being viewed on a mobile device to a video playback device. For example, this may occur when a user is watching a program on a mobile device in a room where a video playback device is installed, and wants to continue viewing that program.

In such cases, with the mobile device described in Patent Document 1, the user must end viewing on the mobile device and then select the program they want to play on the video playback device from a list of programs they have previously viewed. This poses the problem of requiring many operational steps.

The email terminal described in Patent Document 2 allows an information processing device to receive information about whether an internet site has been viewed on a mobile phone by sending a URL. However, when using the email terminal described in Patent Document 2, if the user wishes to view an internet site on the information processing device, the user must operate the information processing device. This poses the problem of requiring many operational steps.

Patent Documents 3 and 4 do not mention handing over viewing of content currently being viewed on a communication terminal device to a television or the like. Therefore, when handing over viewing of content currently being viewed on a communication terminal device to a video playback device, even if the user uses a mobile terminal as a remote control, the user must perform two separate operations, such as ending viewing on the mobile terminal and playing the video on the video playback device, which poses the problem of multiple operational steps.

As such, there was no mention of how to smoothly perform linked operations when attempting to transfer viewing of content currently being viewed on a mobile device to a video playback device.

Taking these issues into consideration, the present invention aims to provide a mobile terminal, information processing device, content display system, and content display method that enable content viewing on a mobile terminal to be smoothly transferred to an information processing device.

One embodiment of the present invention may be configured, for example, as described in the claims.

This invention makes it possible to provide a mobile terminal, information processing device, content display system, and content display method that enable content viewing on a mobile terminal to be smoothly transferred to an information processing device.

The internet browser 208 is stored in memory, and the system control unit 202 reads it from the data storage unit and controls it. The internet browser 208 may also be implemented using a dedicated circuit.

The URL displayed on the Internet browser 208 is received from the data transmission/reception unit 210 or network communication 207 (described later), or obtained by the user entering it using a remote control (not shown) or the like.

The data storage unit 209 is composed of an information recording device such as a flash memory, optical disk, or magnetic disk, and stores program information from received digital broadcasts, content obtained from the Internet 104, and data required for the operation of each processing unit.

The data transmission/reception unit 210 is composed of a communication device that performs wireless communication with external terminals such as the mobile terminal 101 in accordance with standards such as Bluetooth or wireless LAN. The data transmission/reception unit 210 outputs data and signals obtained through this communication to the system control unit 202.

As shown in FIG. 3, the mobile terminal 101 includes a communication unit 300, a system control unit 301, an internet browser 302, a data storage unit 303, an image processing unit 304, a display unit 305, and a data transmission/reception unit 306.

The communication unit 300 has the function of performing wireless communication with the base station 103, and transmits and receives necessary data to and from the base station 103 in accordance with requests from the system control unit 301 (described below). The communication unit 300 is configured, for example, by a transmission/reception device such as a front-end module.

The system control unit 301 is composed of an information processing device such as an MPU or microprocessor, and controls each processing unit required for accessing the Internet and other operations of the mobile terminal 101.

The internet browser 302 is software that manages and controls the display of content obtained from the internet 104 via the communication unit 300 and base station 103 in accordance with instructions from the system control unit 301. The internet browser 302 is stored in memory, and the system control unit 301 reads it from the data storage unit and controls it. The internet browser 302 may also be implemented by a dedicated circuit. The URL of the internet site is configured to be obtained by the URL input unit 102, the communication unit 300, or the data transmission/reception unit 306, which will be described later.

The data storage unit 303 is composed of flash memory or the like, and stores content obtained from the Internet 104 and data necessary for the operation of each processing unit.

The video processing unit 304 is composed of a processing device such as an MPU. The video processing unit 304 converts the content supplied from the internet browser 302 into a format that can be processed by the display unit 305 and outputs it.

The display unit 305 is composed of, for example, a display panel, a panel control circuit, and a panel control driver, and displays images composed of data supplied from the image processing unit 304 on the display panel.

The data transmission/reception unit 306 performs wireless communication with external terminals such as the Internet connection terminal 100 in accordance with standards such as Bluetooth (registered trademark) or wireless LAN, and outputs data and signals obtained through these communications to the system control unit 301.

As described below, the internet connection terminal 100 and the mobile terminal 101 display the internet site currently being displayed on the mobile terminal 101 on the internet connection terminal 100, and the user can also operate the internet connection terminal 100 using the mobile terminal 101. As shown in Figure 4, an overview of the screen configuration and screen transitions of the internet connection terminal 100 and the mobile terminal 101 is shown by State A, screen display 401, button display 402, screen display 403, State B, screen display 404, button display 405, and screen display 406.

State A shows the screen state of both terminals while the user is browsing the Internet on mobile terminal 101. Screen display 401 shows an example when an Internet site is displayed on display unit 305 of mobile terminal 101. Button display 402 is an icon displayed on display unit 305 of mobile terminal 101, and indicates the relationship between the action performed by operating the button related to button display 402. The same is true for button display 405. In this example, when the user uses input unit 102 to press a button corresponding to the selection in button display 402, a process of switching the display of the Internet site described below to Internet connection terminal 100 is performed. This button is usually assigned another function of the mobile phone, and may be configured to be assigned to the switching process when an Internet site is displayed on mobile terminal 101. Screen display 403 shows an example when a television program is displayed on display unit 206 of the Internet connection terminal.

State B shows the screen states of both terminals while the user is browsing the Internet on the Internet connection terminal 100. Screen display 404 shows an example of an operation guide displayed on the display unit 305 of the mobile terminal 101 when using the mobile terminal 101 to operate the Internet connection terminal 100. Furthermore, while screen display 404 is displayed, the mobile terminal 101 can operate the Internet connection terminal 100. Screen display 406 shows an example of an Internet site displayed on the display unit 206 of the Internet connection terminal. Furthermore, screen display 406 shows how the homepage of the Internet site displayed on the mobile terminal 101 in screen state 401 is now displayed on the Internet connection terminal 100. In this example, the user uses the input unit 102 to press a button corresponding to the selection of button display 405, thereby switching the display of the Internet site described below from the Internet connection terminal 100 to the mobile terminal 101.

Here, when switching from state A to state B, the display of the internet site on the mobile terminal 101 ends. Also, when switching from state B to state A, the display of the internet site on the internet connection terminal 100 ends.

In addition, a touch panel input device may be provided instead of button displays 402, 405 and their corresponding buttons.

Next, the operation of the Internet connection terminal 100 and mobile terminal 101 configured as described above will be explained with reference to the flowcharts in Figures 2, 3, 4, and 5.

When the mobile terminal 101 transmits the URL of an internet site via wireless communication in response to a user operation while receiving and playing digital broadcasts, the internet connection terminal 100 displays the internet site indicated by the URL. Following this display, the internet connection terminal 100 also accepts operations on the internet connection terminal 100 from the mobile terminal 101.

First, the operation of the Internet connection terminal 100 to receive and play digital broadcasts will be explained with reference to Figure 2.

Let's assume that the user instructs the Internet connection terminal 100 to start receiving and playing digital broadcasts by operating a remote control (not shown) or the like.

In this case, in response to the instruction, the Internet connection terminal 100 replaces the signal received by the data transmitter/receiver 210 from the remote control instructing the start of reception and playback of digital broadcasting with specified information and notifies the system control unit 202. The system control unit 202 then instructs the digital broadcast receiving unit 200, digital broadcast signal processing unit 201, audio processing unit 203, and video processing unit 205 to start reception processing.

In response to instructions from the system control unit 202, the digital broadcast receiving unit 200 restores data that can be digitally processed by the digital broadcast signal processing unit 201 based on signals obtained from the antenna and cable. It also outputs the restored data to the digital broadcast signal processing unit 201.

The digital broadcast signal processing unit 201 separates the video and audio data contained in the received data, converts them into predetermined video and audio signals, and outputs them. It also synchronizes the output timing of each signal so that the video and audio signals are output in correspondence with each other.

The audio processing unit 203 converts the audio signal received from the digital broadcast signal processing unit 201 into a signal suitable for input to the speaker 204 and outputs it. This causes audio to be output from the speaker 204.

Meanwhile, the video processing unit 205 converts the video signal received from the digital broadcast signal processing unit 201 into a signal suitable for input to the display unit 206 and outputs it. This causes the video to be output from the display unit 206.

Through the above series of operations, digital broadcasts are received and played by the Internet connection terminal 100.

Next, the operation of the Internet connection terminal 100 to access the Internet 104 and display an Internet site will be described with reference to Figure 2.

Assume that a user uses the input unit 102 or the like to send the URL of an internet site to the internet connection terminal 100 via wireless communication using the mobile terminal 101, as described below. In this case, in response to the transmission of the URL, the internet connection terminal 100 receives the wireless communication data at the data transmission/reception unit 210 and notifies the system control unit 202 of the URL obtained from the data.

The system control unit 202 outputs the URL to the internet browser 208. Upon receiving the URL, the internet browser 208 accesses the internet site indicated by the URL via the system control unit 202 and the network communication unit 207, and receives the home page data of the internet site.

The network communication unit 207 accesses the Internet 104 using a communication protocol such as HTTP, receives data from the homepage of the Internet site, and outputs the data to the Internet browser 208 via the system control unit 202. The Internet browser 208 creates an image to be displayed as the homepage from the received data, converts the image into a video signal suitable for input to the video processing unit 205, and outputs it.

The video processing unit 205 converts the video signal obtained from the internet browser 208 into a signal suitable for input to the display unit 206 and outputs it. As a result, the image of the homepage is output from the display unit 206. Furthermore, if there is data to be temporarily stored in the terminal during the above series of operations, the internet browser 208 stores that data in the data storage unit 209 as necessary.

When a specific user operation, described below, is performed while an internet site is displayed on the mobile terminal 101, the mobile terminal 101 transmits the URL of the internet site to the internet connection terminal 100 via wireless communication. Following this transmission, the mobile terminal 101 enters a state in which the internet connection terminal 100 can be operated, allowing the user to operate the internet connection terminal 100 using the mobile terminal 100.

First, the operation of the mobile terminal 101 accessing the Internet 104 via the base station 103 and displaying an Internet site will be described with reference to Figure 3.

Let us assume that the user performs a predetermined operation on the mobile terminal 101 via the input unit 102 of the mobile terminal 101, instructing the display of an internet site on the mobile terminal 101.

In this case, the system control unit 301 of the mobile terminal 101 launches an internet browser 302 that displays an internet site in response to the user's instruction received via the input unit 102. The system control unit 301 instructs the internet browser 302 to access the internet site that is to be displayed immediately after launch via the communication unit 300 and receive the home page data of that internet site.

The communication unit 300 communicates with the base station 103 via wireless communication, accesses the Internet 104 via the base station 103, and receives data for the homepage of the Internet site. The communication unit 300 then outputs the data to the Internet browser 302 via the system control unit 301. The Internet browser 302 creates an image to be displayed as the homepage from the received data, converts the image into a video signal suitable for input to the video processing unit 304, and outputs it. The video processing unit 304 converts the video signal obtained from the Internet browser 302 into a signal suitable for input to the display unit 305, and outputs it. As a result, the image of the homepage is output from the display unit 305. Furthermore, during the above series of operations, if there is data to be temporarily stored in the terminal, the Internet browser 302 saves the data in the data storage unit 303 as necessary.

Similarly, the mobile terminal 101 acquires a URL entered by the user or embedded in a hyperlink, and controls access to the internet site indicated by this URL. 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, the internet site to be displayed on the mobile terminal 101 is displayed on the internet connection terminal 100, and the details of the operation of operating the internet connection terminal 100 using the mobile terminal 101 following this display will be explained with reference to the flowcharts in Figures 4 and 5.

In Figure 5, the operation of the mobile terminal 101 is shown in box 500, and the operation of the internet connection terminal 100 is shown in box 513. In the following explanation, the operation flow within box 500 and the operation flow within box 513 are explained in parallel, thereby simultaneously explaining the operation flow of each of the mobile terminal 101 and the internet connection terminal 100, and the relationship between the operation flows of both terminals. In the following explanation, the mobile terminal 101 will be taken as an example to be a mobile phone, and the internet connection terminal 100 will be taken as an example to be a television with internet connection functionality.

First, the user sets the type of television to be used for browsing the Internet (described below) on a specific settings screen on their mobile phone by, for example, specifying the manufacturer and model number using input unit 102 (step 501). The data storage unit 303 stores the input model number and other numbers, user operations, and signals and information to be transmitted, in association with each other. The control means 301 then sets commands to be transmitted to the television by associating the input operations with the information to be transmitted in the data storage unit. Setting these commands enables the mobile phone to transmit commands that can be recognized by the television.

The user turns on the television through a specific operation, and the television receives and plays the broadcast received from the digital broadcast receiving unit 200 using the mechanism described above (step 514). Step 514 is the state when the user is using the television alone, and this state is referred to as the television's normal mode. A power-on state refers to a state in which at least the main power is on.

The user performs an operation to start displaying a specified Internet page on the mobile phone. This operation causes the mobile phone's display unit 305 to display an Internet site, as shown in screen display 401, and the user can view the Internet site (step 502).

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

Suppose that while browsing the Internet site, the user attempts to view the same site on a television. In this case, the user uses input unit 102 to select button 402 displayed on display unit 305 of the mobile phone (step 503). This operation puts the mobile phone into display switching mode, a state in which the mobile phone can switch the display of the Internet site to a television.

When the mobile phone enters display switching mode, the mobile phone's system control unit 301 transmits the URL of the internet site being displayed to the television via the data transmission/reception unit 306 (step 504). After transmitting the URL, or in conjunction with transmitting the URL, the system control unit 301 controls the display unit 305 and other components to terminate the display of the internet site on the mobile terminal. The mobile phone may also be configured to transmit a signal to the television, along with the URL, instructing it to display the internet site.

The television receives the URL from the mobile phone via data transmission/reception unit 210 (step 515), connects to the Internet site indicated by the URL using the procedure described above, and displays the Internet site on display unit 206, as shown on screen display 406 (step 516). Step 516 puts the television in a state where it can accept operations from the mobile phone, and this state is called the external operation acceptance mode. Furthermore, the operation of step 516 switches the television display from the previously displayed content to the content corresponding to the URL received from the mobile phone.

On the other hand, after sending the URL, the mobile phone is configured so that the system control unit 301 can use some of the keys on the input unit 102 to operate the television (described below), and this state is called the operation switching mode. The display unit 305 displays a message explaining to the user the operations that can be performed by pressing the keys, as shown on screen display 404, for example (step 505).

Here, being able to operate the television means that by pressing some keys on the input unit 102, data indicating an operation for the television can be transmitted, which can identify the type of television set in step 501. This data will be the same as the data transmitted by a remote control for the type of television set in step 501, for example. As a result, when the user attempts to perform an operation such as moving between selection items on an Internet site displayed on the television or confirming a selection, the user presses a key on the input unit 102 of the mobile phone that corresponds to the operation shown on screen display 404, thereby transmitting information and signals indicating instructions for the operation from the mobile phone to the television (step 506). The operation of this step causes the mobile phone to function as a remote control for the television. Furthermore, the operation of this step is performed, for example, by control 301.

The television receives the information and signals indicating the operation instructions from the mobile phone via the data transmission/reception unit 210, and, under the control of the system control unit 201, reflects the contents of the instructions in the screen display 406 that displays the Internet and in the operation of the Internet browser 208 (step 517).

When the user described above wishes to return from browsing an internet site on a television to browsing the internet site on a mobile phone, the user selects button display 405 displayed on the mobile phone's display unit 305 (step 507). This operation causes the mobile phone to transmit data indicating the end of the internet display to the television via communication via data transmission/reception unit 306 (step 508). Furthermore, after transmitting the URL, or in conjunction with transmitting the URL, system control unit 202 controls display unit 206, etc., to terminate the display of the internet site on the television.

When the television receives the data via the data transmission/reception unit 210, it stops displaying the internet site (step 518). Furthermore, it transmits the URL of the internet site last displayed by the television to the mobile phone via the data transmission/reception unit 210 (step 519), and displays the television program that was displayed before the internet display began, as shown in screen display 403 (step 520). In step 520, the television returns to a standalone state and enters normal mode. Also in step 520, the television resumes displaying the content that was displayed before receiving the URL from the mobile phone. Note that in step 520, the television may simply end displaying the internet site. This reduces the user's effort in ending the television display.

The mobile phone also receives the URL of the internet site last displayed on the television, accesses the internet site at that URL, and displays it (step 510). This operation switches the display of the internet site from the television to the mobile phone, and the mobile phone enters display switching mode. The operation of this step is performed, for example, under the control of the control unit 301. The operation of this step also resumes displaying the internet site on the mobile phone.

At this time, the system control unit 301 changes the functions assigned to some of the keys on the input unit 102 that were used to operate the television from the mobile phone, and treats them as keys for operating a normal mobile phone (step 511). The screen display also switches, for example, from screen display 404 to screen display 401, and the user continues browsing the Internet site displayed as in screen display 401 (step 512). In step 512, the mobile phone returns to a state where it can operate on its own again, and so the mobile phone enters 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 via wireless communication, the internet site is displayed on the internet connection terminal 100 that receives the URL, and the user then operates the internet connection terminal 100 that is displaying the internet site using the mobile terminal 101.

When the user simply presses the button once to switch the Internet display to the Internet connection terminal 100, the mobile terminal 101 transitions from normal mode, in which the mobile terminal 101 operates alone, to display switching mode, in which the display is switched to the Internet connection terminal 100, and then to operation switching mode, in which the Internet connection terminal 100 is operated by the mobile terminal 101. Furthermore, when the user wishes to display the Internet on the mobile terminal 101 again, simply pressing the button once to view the Internet on the mobile terminal 101 will end the operation switching mode, transition to display switching mode, and then return to normal mode, a series of operations.

This allows the user to display the internet site on a larger screen with simple operations using only the mobile terminal 100, without having to operate the device on which the new internet site is to be displayed, and then continue to use the mobile terminal 100 to operate the device on which the new internet site is displayed, allowing the user to smoothly switch the display of the internet site between different devices.

In the above embodiment, the screen display 406 displays the internet site in full screen on the display unit 206 of the internet connection terminal 101, but the internet site may also be displayed on only part of the screen.

In this embodiment, when an internet site is being viewed on the mobile terminal 101, the entity that performs the communication via the internet network and the process of outputting the received information as video switches from the mobile terminal 101 to the internet connection device 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 can perform operations for browsing the internet site on the mobile terminal 101, while also being able to browse the internet site via faster communication.

Furthermore, in this embodiment, examples of Internet connection terminals include televisions, set-top boxes, and DLNA-compatible servers. Applying this embodiment to these devices can solve the problems that arise in the following situations.

For example, these information processing devices such as televisions are often installed in living rooms and shared by multiple people. For this reason, there are times when viewing on a television or other display needs to be suddenly interrupted. Specifically, this occurs when multiple people are watching television, making it difficult for individuals to view internet sites.

In this case, if a user wants to continue viewing an internet site or the like on their mobile terminal 100, they could, for example, turn off the internet site display on the television, start the browser on their mobile phone with communication capabilities, and enter the URL that was displayed on the screen into their mobile phone, thereby continuing viewing on their mobile phone with communication capabilities. However, this method has the problem of requiring a large number of steps.

In contrast, the mobile terminal 101 and internet connection device 100 of this embodiment solve the above-mentioned problems, and not only can the display and communication subject be switched from the mobile terminal 101 to the internet connection device 100, but it also makes it easy to switch from the internet connection device 100 to the mobile terminal.

In this embodiment, an internet site has been described as an example of content information, but this is not a limitation of this embodiment, and information indicating other content, such as a television program, may also be used. Furthermore, a URL has been described as an example of identification information, but this is not a limitation. For example, information indicating a television program channel may also be used as identification information.

Next, we will explain Example 2. In this example, we will explain a method for achieving operations equivalent to those of Example 1 using infrared communication for communication used to send and receive URLs and instructions for various operations in the Internet connection terminal 100 and mobile terminal 101 of Example 1.

This embodiment will be described below with reference to the drawings. Furthermore, in the following, parts equivalent to those in the previous embodiment will be given the same reference numerals, and their descriptions will be omitted to avoid duplication.

The internet connection terminal 100 of Example 2 shown in Figure 6 differs from Example 1 shown in Figure 2 in that the data transmission/reception unit 210 is an infrared transmission/reception unit 600, which transmits and receives data using, for example, an infrared command communication format specified by the manufacturer or infrared communication conforming to the IrDA standard.

The mobile terminal 101 of Example 2 shown in Figure 7 differs from Example 1 shown in Figure 3 in that the data transceiver unit 306 is an infrared transceiver unit 700, which transmits and receives data using infrared signals that comply with the IrDA standard, for example.

The operation of this embodiment will be explained below with reference to the flowcharts in Figures 6, 7, and 8. In this embodiment, when the URL of an internet site is transmitted from the mobile terminal 101 via infrared communication in response to a user operation while the internet connection terminal 100 is receiving and playing digital broadcasts, the internet connection terminal 100 displays the internet site, and following this display, accepts operation of the internet connection terminal 100 by the mobile terminal 101 via infrared communication.

Figure 8 adds steps shown in bold frames to the flowchart of Figure 5 used in Example 1 of the present invention. As with Figure 5, Figure 8 shows the operation of mobile terminal 101 within box 500, and the operation of internet connection terminal 100 within box 513. In the following explanation, the operation flow within box 500 and the operation flow within box 513 will be explained in parallel, thereby simultaneously explaining the operation flow of mobile terminal 101 and internet connection terminal 100, and the relationship between the operation flows of both terminals. In the following explanation, a mobile phone will be used as an example of mobile terminal 101, and a television with internet connection functionality will be used as an example of internet connection terminal 100.

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

The user turns on the television using a specified operation, and the television receives and plays the broadcast received from the digital broadcast receiving unit 200 using the mechanism described above (step 514).

The user performs an operation to start displaying a specified Internet page on the mobile phone. This operation causes the mobile phone's display unit 305 to display an Internet site, as shown in screen display 401, and the user can view the Internet site (step 502).

Suppose that while browsing the Internet site, the user attempts to view the same site on a television. In this case, the user selects button 402 displayed on the display unit 305 of the mobile phone (step 503).

As a result of this operation, the infrared transceiver 700 of the mobile phone instructs the television to begin IrDA communication by sending an infrared command that can be recognized by the type of television set in step 501 (step 800). The television, upon receiving this infrared command, begins IrDA communication (step 801) and requests an IrDA communication connection from the mobile phone (step 802). Meanwhile, immediately after sending the infrared command in step 800, the mobile phone prepares to begin the IrDA connection, responds to the IrDA communication connection request from the television, and an IrDA communication connection is established between the television and the mobile phone (step 803). Furthermore, the system control unit 301 controls the display unit 305, etc., to end the display of the Internet site on the mobile terminal 101 after or in conjunction with sending the URL.

Once the IrDA communication connection has been established, the mobile phone's system control unit 301 transmits the URL of the displayed Internet site to the television via IrDA communication using the infrared transceiver unit 700 (step 504).

The television receives the URL from the mobile phone via infrared transmitter/receiver unit 600 (step 515). The television then transmits data indicating successful reception of the URL to the mobile phone via IrDA communication via infrared transmitter/receiver unit 600 (step 804). When the mobile phone receives the data indicating successful reception of the URL (step 805), it disconnects IrDA communication via infrared transmitter/receiver unit 700 (step 806). This disconnection also causes the television to terminate IrDA communication via infrared transmitter/receiver unit 600, and it becomes ready to accept normal infrared commands from a remote control (not shown). Furthermore, it connects to the Internet site indicated by the URL using the procedure described above, and displays the Internet site on display unit 206, as shown in screen display 406 (step 516).

On the other hand, after transmitting the URL, the mobile phone's system control unit 301 uses some of the keys on the input unit 102 to configure the television (described below) to be operable, and the display unit 305 displays a message explaining to the user the operations that can be performed by pressing the keys, as shown on screen display 404, for example (step 505). Here, the configuration to operate the television means that by pressing some of the keys on the input unit 102, an infrared command to operate the television, which can identify the type of television set in step 501, is transmitted via the infrared transceiver unit 700. The infrared command will be the same as the infrared command transmitted by a remote control (not shown) for the type of television set in step 501. Thus, when the user wishes to perform an operation such as moving a selection item on an internet site displayed on the television or confirming a selection item, the user presses a key on the input unit 102 of the mobile phone that corresponds to the operation shown on screen display 404, thereby transmitting the instruction for the operation from the mobile phone to the television (step 506).

Upon receiving the operation instruction from the mobile phone, the television reflects the content of the instruction in the screen display 406 that displays the Internet and in the operation of the Internet browser 208 (step 517).

When a user such as the one described above returns from browsing an internet site on a television to browsing an internet site on a mobile phone, the user selects button display 405 displayed on the mobile phone's display unit 305 (step 507). This operation causes the mobile phone to send an infrared command to the television via infrared transmitter/receiver unit 700 indicating the end of the internet display (step 508).

Upon receiving the infrared command, the television stops displaying the Internet site (step 518). The television then initiates IrDA communications and requests an IrDA communication connection from the mobile phone (step 808). Meanwhile, immediately after sending the infrared command in step 508, the mobile phone initiates IrDA communications, receives the IrDA communication connection request from the television, and establishes an IrDA communication connection (step 809).

Once the communication connection has been established, the television transmits the URL of the Internet site last displayed on the television to the mobile phone via the infrared transceiver 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 the IrDA communication via the infrared transceiver 600, and enters a state in which it can accept normal infrared commands from a remote control (not shown) or the like (step 812). Furthermore, the television displays the television program that was displayed before the Internet display began, as shown on screen display 403, for example (step 520).

Meanwhile, the mobile phone, having received the URL of the Internet site last displayed by the television, terminates the IrDA communication (step 813), accesses the Internet site at that URL, and displays it (step 510). At this time, system control unit 301 changes the functions assigned to some of the keys on input unit 102 that were used to operate the television from the mobile phone, and treats them as keys for operating a regular mobile phone (step 511). Furthermore, the screen display switches, for example, from screen display 404 to screen display 401, and the user continues browsing the Internet site displayed as in screen display 401 (step 512).

In this way, the URL of the internet site to be viewed on the mobile terminal 101 is sent to the internet connection terminal 100 via infrared communication, the internet site is displayed on the internet connection terminal 100 that receives the URL, and the user then operates the internet connection terminal 100 that displays the internet site using the mobile terminal 101. Furthermore, when sending these URLs and operation instructions, the television switches between communication via infrared commands received from a remote control or the like and communication via IrDA as described above, thereby enabling operation of the television using a mobile phone.

This allows the user to display the internet site on a larger screen with simple operations using only the mobile terminal 100, without having to operate the device on which the new internet site is to be displayed, and then continue to use the mobile terminal 100 to operate the device on which the new internet site is displayed, allowing the user to smoothly switch the display of the internet site between different devices.

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

Furthermore, in this embodiment, examples of the Internet connection terminal 100 include a television device, a set box device, and a DLNA-compatible server. Applying this embodiment to these devices can solve the problems that arise in the following situations.

For example, the general-purpose infrared commands used by television devices are limited in the types of commands that can be sent and received, and there are also limitations on communication speeds. On the other hand, signals indicating URLs and operational information contain a larger amount of information than signals sent and received simply to turn the power on and off with a remote control. For this reason, when using general-purpose infrared commands, it is not possible to send and receive URLs and operational information between a mobile terminal and an information processing device, or even if it is possible, it takes a long time to send and receive the information.

On the other hand, when performing IrDA-compliant communications, it is necessary to establish communications between the mobile terminal 101 and the Internet connection terminal 100 in order to send and receive information. For this reason, unless communications are switched from general-purpose commands to IrDA, the information processing device must always be in a state where it is waiting for IrDA communications. If the connection is always kept in an established state, a problem occurs in which the Internet connection terminal 100 is unable to communicate with other devices via infrared.

In contrast, this embodiment switches communications using a general-purpose infrared command as a trigger, eliminating the above problem and improving usability.

In this embodiment, IrDA communication has been used as an example, but it is also possible to use Bluetooth communication, wireless communication such as wireless LAN, or short-range communication such as 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 this is not a limitation of this embodiment, and information indicating other content, such as a television program, may also be used. Furthermore, a URL has been described as an example of identification information, but this is not a limitation. For example, information indicating a television program channel may also be used as identification information.

Next, we will explain Example 3. In this example, when sending and receiving URLs and various operational instructions in the internet connection terminal 100 and mobile terminal 101 of Example 1, we will explain a method for realizing an operation in which not only the internet site indicated by the URL is displayed, but also the state in which the internet site was displayed on the mobile terminal 101 is taken over from the mobile terminal 101 to the internet connection device 100.

Here, the displayed state refers to, for example, the state in which the screen displayed after logging in to an internet site that requires authentication is displayed on the mobile terminal 101. Also, the displayed state refers to, for example, the display state after a change on an internet site where the content display state changes dynamically while the URL remains the same.

The information indicating the display state may include, for example, information indicating a history of user operations that affected the display on the display unit 305. The information indicating the display state may also include information that is not included in the URL and that affects the display on the display screen 305 when browsing an internet site. The information indicating the display state may also be information indicating character encoding such as Shift-JIS, EUC, or UTF-8. For example, the information indicating the display state may be a cookie. The information indicating the display state may also be information indicating the position of the pointer or scroll bar displayed on the display unit 305 when the display changes when an internet site is displayed on the mobile terminal 101. The position of the pointer may also be information indicating the relative position of the pointer on the display screen. This makes it possible to reproduce the relative position on the internet connection terminal 100 even if the display areas of the mobile terminal 101 and the internet connection terminal 100 are different in size.

This embodiment will be described below with reference to the drawings. Note that this description will focus on an example in which an internet site involving authentication processing is handed over from a mobile terminal 101 to an internet connection terminal 100. Furthermore, in the following, parts equivalent to those in the previous embodiment will be given the same reference numerals, and their description will be omitted to avoid duplication.

Figure 9 shows an example of the data components and content of an operation history 900 of user operations on an internet site that involves authentication processing and is recorded by the mobile terminal 101 when the user browses the internet site in this embodiment, and the mobile terminal 101 stores the operation history 900 in the data storage unit 303.

The information included in this operation history 900 may include, for example, character strings entered into text boxes, information indicating buttons or icons clicked on Internet sites, and information indicating selections made in list boxes. The information included in the operation history 900 may also include information indicating URLs displayed as a result of such operations.

Figure 10 shows an example of the data components and content of an operation history 1000 of user operations on Internet content recorded by the mobile terminal 101 when a user browses Internet content whose content changes dynamically without changing the URL in this embodiment, 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 coordinate position of the clicked point.

Figure 11 shows transmission data 1100 that the mobile terminal 101 sends to the internet connection terminal 100 in this embodiment. The transmission data 1100 consists of header data 1101 containing identification information such as the data length and data type, the URL 1102 of the internet site, and the operation history 900.

The operation of this embodiment will be described below with reference to the flowcharts in Figures 9, 10, 11, and 12. In this embodiment, the mobile terminal 101 records an operation history 900 of user operations on an internet site when, for example, the internet site viewed by the user is an internet site that involves authentication processing or internet content whose content changes dynamically without changing the URL. Furthermore, in a manner similar to that of embodiment 1, when the mobile terminal 101 transmits the URL of the internet site to the internet connection terminal 100, it also transmits transmission data 1100 consisting of the URL and the operation history 900. Furthermore, upon receiving the transmission data 1100, the internet connection terminal 100 accesses the internet site indicated by the URL, performs the same user operation on the displayed internet site as indicated by the operation history 900, and displays the internet site in a state where the operation has been completed.

Figure 12 adds steps shown in bold frames to the flowchart of Figure 5 used in Example 1 of the present invention. As with Figure 5, Figure 12 shows the operation of mobile terminal 101 within box 500 and the operation of internet connection terminal 100 within box 513, and in the following explanation, the operation flow within box 500 and the operation flow within box 513 will be explained in parallel. In other words, the operation flow of each of mobile terminal 101 and internet connection terminal 100, as well as the relationship between the operation flows of both terminals, will be explained simultaneously. Furthermore, in the following explanation, mobile terminal 101 will be taken as an example to be a mobile phone, and internet connection terminal 100 will be taken as an example to be a television with internet connection functionality.

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

In this case, the mobile phone does not need to record operation history 900 and operation history 1000 for all Internet sites visited by the user. For example, if the Internet site is one where security is important, such as one whose URL begins with HTTPS (Hypertext Transfer Protocol Security), if the Internet site is dynamically generated using a function such as ASP (Active Server Pages), or if the document configuration information of the displayed Internet site includes interactive content such as FLASH (registered trademark), the mobile phone may record operation history 900 and operation history 1000 only for these Internet sites. If the Internet site includes FLASH or ASP content, the source file defines the content, and the mobile phone can determine the type of site from this tag.

Furthermore, even if the internet site is a dynamically generated internet site, it is not necessary to store all operation history in the operation history 1100. The operation history may be configured to record history related to operations that have caused changes to the display. 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 input performed on that dynamic content.

Next, in this embodiment, in step 503, when the user attempts to view the Internet site on the television and selects the button corresponding to button display 402 displayed on the display unit 305 of the mobile phone, the mobile phone creates transmission data 1100 that includes the URL 1102 of the Internet site that was the starting point for recording operation history 900 or operation history 1000, operation history 900 or operation history 1000, and header data 1101, and transmits this transmission data 1100 to the television. Furthermore, after transmitting the URL, the system control unit 301 controls the display unit 305, etc., 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 at URL 1102, performs the operation indicated in operation history 900 or operation history 1000 on the internet site, and displays the internet site in its state after the operation was performed (step 1204).

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

In this way, if the internet site the user is viewing on their mobile phone is one that requires authentication processing or is internet content whose content changes dynamically without changing the URL, the television records operation history 900 and operation history 1000 of user operations on the internet site in data storage unit 209. Furthermore, the television transmits transmission data 1100 to the television, which consists of the URL of the internet site that was the starting point for recording operation history 900 and operation history 1000, and operation history 900 and operation history 1000. Furthermore, upon receiving transmission data 1100, the television accesses the internet site indicated by the URL, performs the operations on the internet site indicated by operation history 900 and operation history 1000, and displays the internet site in a state where the operations have been completed.

This allows users to smoothly switch access to the same Internet site between different terminals without having to perform authentication processing or content operations again on the terminal accessing the new Internet site, even if the Internet site they are viewing requires authentication processing or contains Internet content that changes dynamically without changing the URL.

Furthermore, when a URL is sent from a mobile phone to an information processing device such as a television without sending display information, the internet site indicated by the URL will be displayed on the information processing device without any operations that would affect the display. Therefore, the more complex the structure of the internet site, the more operations are required from simply sending the displayed URL until the operations on the mobile phone are reflected. However, the mobile terminal 101 and internet connection terminal 100 of this embodiment make it possible to reduce the effort required for these operations.

The above describes each embodiment. However, instead of the mobile terminal 101, other information processing terminals can also be used to communicate via the Internet and smoothly switch access between multiple terminals.
