Description

[Technical Field]

[0001] The present invention relates to a display device. [Background technology]

[0002] Mobile phones that can access Internet sites and television programs are becoming increasingly popular. 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 do on their mobile phones, as well as technologies that allow users to use their mobile phones as remote controls to operate televisions.

[0003] 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 whole program from start to finish on an indoor recording and playback device after returning home.

[0004] 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 the email data is 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 URL information is used to access a server device connected to a wireless communication network different from the wireless communication network, and the information obtained is displayed on the display device.

[0005] Furthermore, Patent Document 3 describes the use of a communication terminal device that normally has a different function as a remote control for remotely operating another communication terminal device.

[0006] Patent Document 4 describes a video conference system that uses a mobile phone connected to a video conference server via the Internet and capable of exchanging information with the video conference server, and a display device that is connected to the mobile phone via a communication function and can display the information, to control devices connected to the video conference server via a network, the video conference system comprising information display means that displays a first video phone screen that displays the information in text on a first display of the mobile phone, and a second video phone screen that displays image information included 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 video on a PC display screen. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2006-286855 A (Abstract) [Patent Document 2] JP 2005-135346 A (Abstract) [Patent Document 3] JP 2006-338406 A (paragraph number 0152) [Patent Document 4] JP 2007-74265 A (Claim 7, paragraph 0068) Summary of the Invention [Problem to be solved by the invention]

[0008] The mobile terminal etc. of Patent Document 1 is configured to display a list of programs that have been watched in the past (Figure 7) and play a selected program from the list on a video playback device in order to meet requests such as wanting to watch a program that was watched while out again on a large screen when returning home, or wanting 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 whole program from start to finish on an indoor recording and playback device when you return home (paragraph 0006).

[0009] However, there is a demand for a video playback device to take over viewing of content that is currently being viewed on a mobile terminal, for example, when a user is viewing a program on a mobile terminal in a room where a video playback device is installed and wants to take over viewing of that program.

[0010] In such a case, the mobile terminal described in Patent Document 1 requires the user to end viewing on the mobile terminal and then select the program they want to play on the video playback device from a list of programs they have previously viewed, which poses a problem of requiring many operational steps.

[0011] According to the email terminal described in Patent Document 2, by transmitting a URL, an information processing device can receive information on whether an internet site has been viewed on a mobile phone. 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 many operational steps.

[0012] Patent Documents 3 and 4 do not describe handing over the viewing of content that was being viewed on a communication terminal device to a television, etc. Therefore, when handing over the viewing of content that is 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 an operation to end viewing on the mobile terminal and an operation to play the video on the video playback device, respectively, which poses a problem of many operational steps.

[0013] As described above, there is no mention of how to smoothly perform a linked operation when attempting to transfer viewing of content currently being viewed on a mobile terminal to a video playback device.

[0014] In consideration of the above problems, the present invention aims to provide a mobile terminal, an information processing device, a content display system, and a content display method that enable content viewing on a mobile terminal to be smoothly handed over to an information processing device. [Means for solving the problem]

[0015] One embodiment of the present invention may be configured, for example, as described in the claims. [Effects of the Invention]

[0016] According to the present invention, it is possible to provide a mobile terminal, an information processing device, a content display system, and a content display method that enable viewing of content on a mobile terminal to be smoothly handed over to an information processing device.

Fig. 1 shows an overview of the related equipment and connection environment when the internet connection terminal 100 and mobile terminal 101 connect to the internet 104 via an input unit 102, a base station 103, and the internet 104. The mobile terminal 101 refers to a portable information processing terminal such as a mobile phone, a PDA, or a smartphone.

[0021] The input unit 102 is an input device for the mobile terminal 101, and is configured with, for example, a plurality of buttons, etc. A user operates the mobile terminal 101 using the keys, buttons, and dials provided on the input unit 102.

[0022] The base station 103 is a base station with which the mobile terminal 101 communicates wirelessly when connecting to the Internet.

[0023] The Internet 104 is a conceptual representation of a collection of so-called web servers and various internet services, and is connected to an internet connection terminal 100 and a base station 103. A mobile terminal 101 connects to the Internet 104 via the base station 103.

[0024] The internet connection terminal 100 is a device that has a function of outputting video and connecting to the internet, such as a television device, an STB, or a DLNA (Digital Living Network Alliance) compatible home server. The internet connection terminal 100 is capable of connecting to the internet and displaying websites, etc., and is also capable of viewing digital broadcasts distributed via terrestrial waves, BS, CS, the internet, etc. As shown in Fig. 2, the internet connection terminal 100 includes a digital broadcast receiving unit 200, a digital broadcast signal processing unit 201, a system control unit 202, an audio processing unit 203, a speaker 204, a video processing unit 205, a display unit 206, a network communication unit 207, an internet browser 208, a data storage unit 209, and a data transmission / reception unit 210.

[0025] The digital broadcast receiving unit 200 is a circuit that receives desired broadcast data from an antenna or cable, and restores data that can be digitally processed by the digital broadcast signal processing unit 201 (described later) based on the received signal.

[0026] The digital broadcast signal processing unit 201 is composed of, for example, a signal separator that performs demuxing, a compound device that performs decoding, etc. The digital broadcast signal processing unit 201 inputs digital broadcast data obtained from the digital broadcast receiving unit 200, separates the audio data and video data contained in the data, converts them into data formats that can be processed by the audio processing unit 203 and the video processing unit 205, which will be described later, and outputs them.

[0027] The system control unit 202 is configured by, for example, a microprocessor, and controls the operation of each processing unit required for playing digital broadcasts and accessing the Internet.

[0028] The audio processing unit 203 is configured by, for example, an AD converter, etc. The audio processing unit 203 converts the digital audio data supplied from the digital broadcast signal processing unit 201 into analog audio data, and outputs it to the speaker 204.

[0029] The speaker 204 converts the analog audio data supplied from the audio processing unit 203 into audio and emits the audio.

[0030] The video processing unit 205 is configured by a processing device such as an ASIC, FPGA, MPU, etc. The video processing unit 205 converts video data supplied from the digital broadcast signal processing unit 201 or an internet browser 208 (described later) into a format that can be processed by the display unit 206 and outputs the converted data.

[0031] The display unit 206 is configured with a display device such as a liquid crystal display, a plasma display, etc. The display unit 206 is configured with a display panel, a panel control circuit, and a panel control driver, and displays on the display panel an image configured with data supplied from the image processing unit 205. Here, if the internet connection terminal is an STB (set-top box) or a DLNA-compatible home server, instead of being provided with the display unit 206, it outputs an image signal configured in an RGB format or the like to an external display device.

[0032] The network communication unit 207 is configured by, for example, a communication module that can be connected to the Internet, etc. The network communication unit 207 transmits and receives predetermined data to and from the Internet 104 in accordance with a request from the system control unit 202.

[0033] The internet browser 208 is software that, in accordance with instructions from the system control unit 202, controls and manages the display of content obtained from the internet 104 via the network communication unit 207. 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 by a dedicated circuit.

[0034] The URL displayed on the internet browser 208 is received from the data transmission / reception unit 210 or the network communication 207, which will be described later, or is acquired by the user inputting it using a remote control or the like (not shown).

[0035] 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 of received digital broadcasts, content obtained from the Internet 104, and data necessary for the operation of each processing unit.

[0036] The data transmitter / receiver 210 is configured by a communication device that performs wireless communication with an external terminal such as the mobile terminal 101 in accordance with a standard such as Bluetooth or wireless LAN. The data transmitter / receiver 210 outputs data and signals obtained through this communication to the system control unit 202.

[0037] 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, a video processing unit 304, a display unit 305, and a data transmission / reception unit 306.

[0038] The communication unit 300 has a 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 a request from a system control unit 301 (described later). The communication unit 300 is configured by, for example, a transmission / reception device such as a front-end module.

[0039] The system control unit 301 is configured with an information processing device such as an MPU or a microprocessor, and controls each processing unit required for accessing the Internet and other operations of the mobile terminal 101 .

[0040] Internet browser 302 is software that manages and controls the display of content obtained from Internet 104 via communication unit 300 and base station 103 in accordance with instructions from system control unit 301. Internet browser 302 is stored in memory, and system control unit 301 reads it from the data storage unit and controls it. Internet browser 302 may also be implemented by a dedicated circuit. The URL of an Internet site is configured to be obtained by URL input unit 102, communication unit 300, or data transmission / reception unit 306, which will be described later.

[0041] The data storage unit 303 is configured by a flash memory or the like, and stores content acquired from the Internet 104 and data required for the operation of each processing unit.

[0042] The video processing unit 304 is configured by a processing device such as an MPU, etc. 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 the converted content.

[0043] The display unit 305 is configured, for example, by a display panel, a panel control circuit, and a panel control driver, and displays an image configured by data supplied from the image processing unit 304 on the display panel.

[0044] The data transmitter / receiver 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.

[0045] As will be described later, 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 further 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.

[0046] State A shows the screen states of both terminals while the user is browsing the Internet on the mobile terminal 101. Screen display 401 shows an example when an Internet site is displayed on the display unit 305 of the mobile terminal 101. Also, button display 402 is an icon displayed on the display unit 305 of the 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 to the Internet connection terminal 100, which will be described later, 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 the mobile terminal 101. Screen display 403 shows an example when a television program is displayed on the display unit 206 of the Internet connection terminal.

[0047] 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 when an operation guide is 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 when an Internet site is displayed on the display unit 206 of the Internet connection terminal. Furthermore, screen display 406 shows how the homepage of the Internet site that was displayed on the mobile terminal 101 in screen state 401 is now displayed on the Internet connection terminal 100. In this example, when the user uses input unit 102 to press a button corresponding to the selection of button display 405, a process is performed to switch the display of the Internet site from the Internet connection terminal 100 to the mobile terminal 101, as described below.

[0048] Here, when switching from state A to state B, the display of the internet site on the mobile terminal 101 is terminated. Also, when switching from state B to state A, the display of the internet site on the internet connection terminal 100 is terminated.

[0049] Instead of the button displays 402 and 405 and the corresponding buttons, a touch panel type input device may be provided.

[0050] Next, the operation of the internet connection terminal 100 and mobile terminal 101 configured as above will be described with reference to the flowcharts of FIGS.

[0051] When the URL of an internet site is transmitted by wireless communication from the mobile terminal 101 in response to a user operation while receiving and playing back a digital broadcast, the internet connection terminal 100 displays the internet site indicated by the URL. After this display, the internet connection terminal 100 also accepts operations of the internet connection terminal 100 from the mobile terminal 101.

[0052] First, the operation of the internet connection terminal 100 to receive and play back digital broadcasts will be described with reference to FIG.

[0053] It is assumed that the user instructs the Internet connection terminal 100 to start receiving and playing back digital broadcasts by operating a remote control or the like (not shown).

[0054] In this case, in response to the instruction, the internet connection terminal 100 replaces the signal that the data transmitter / receiver 210 has received from the remote controller, which instructs the start of reception and playback of digital broadcasting, with predetermined information and notifies the system control unit 202. The system control unit 202 instructs the digital broadcasting receiving unit 200, digital broadcasting signal processing unit 201, audio processing unit 203, and video processing unit 205 to start reception processing.

[0055] In response to an instruction 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. The digital broadcast receiving unit 200 also outputs the restored data to the digital broadcast signal processing unit 201.

[0056] The digital broadcast signal processor 201 separates the video data and audio data contained in the received data, converts them into predetermined video signals and audio signals, and outputs them. At this time, the output timing of each signal is synchronized so that the video signals and audio signals are output in correspondence with each other.

[0057] 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 the converted signal.

[0058] On the other hand, video processing unit 205 converts the video signal received from digital broadcast signal processing unit 201 into a signal suitable for input to display unit 206, and outputs the converted signal.

[0059] Through the above series of operations, the internet connection terminal 100 receives and plays back digital broadcasts.

[0060] Next, the operation of the internet connection terminal 100 accessing the internet 104 and displaying an internet site will be described with reference to FIG.

[0061] As will be described later, it is assumed 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 by wireless communication using the mobile terminal 101. 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.

[0062] System control unit 202 outputs the URL to internet browser 208. Upon receiving the URL, internet browser 208 accesses the internet site indicated by the URL via system control unit 202 and network communication unit 207, and receives the home page data of the internet site.

[0063] 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 a homepage from the received data, converts the image into a video signal suitable for input to the video processing unit 205, and outputs the image.

[0064] Video processing unit 205 converts the video signal obtained from internet browser 208 into a signal suitable for input to display unit 206 and outputs it. As a result, the image of the homepage is output from display unit 206. Furthermore, in the series of operations described above, if there is data to be temporarily stored in the terminal, internet browser 208 stores the data in data storage unit 209 as necessary.

[0065] When a specific user operation, described below, is performed while displaying an internet site, the mobile terminal 101 transmits the URL of the internet site to the internet connection terminal 100 via wireless communication, and following this transmission, the mobile terminal 101 becomes capable of operating the internet connection terminal 100, allowing the user to operate the internet connection terminal 100 using the mobile terminal 100.

[0066] 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 FIG.

[0067] It is assumed that the user performs a predetermined operation on the mobile terminal 101 via the input unit 102 of the mobile terminal 101 to instruct the mobile terminal 101 to display an internet site thereon.

[0068] In this case, the system control unit 301 of the mobile terminal 101 starts up the internet browser 302 that displays the 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 startup via the communication unit 300 and to receive the home page data of the internet site.

[0069] Communication unit 300 communicates with base station 103 via wireless communication, accesses Internet 104 via base station 103, and receives data for the homepage of the Internet site. Communication unit 300 then outputs the data to Internet browser 302 via system control unit 301. Internet browser 302 creates an image to be displayed as a homepage from the received data, converts the image into a video signal suitable for input to video processing unit 304, and outputs it. Video processing unit 304 converts the video signal obtained from Internet browser 302 into a signal suitable for input to display unit 305, and outputs it. As a result, the image of the homepage is output from display unit 305. Furthermore, during the above series of operations, if there is data to be temporarily stored in the terminal, Internet browser 302 stores the data in data storage unit 303 as necessary.

[0070] Similarly, the mobile terminal 101 acquires a URL entered by the user or embedded in a hyperlink, and controls the mobile terminal 101 to access the internet site indicated by the URL. The system control unit 301 also controls the internet browser 302 to store the URL of the internet site displayed in the data storage unit 303.

[0071] 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 of Figures 4 and 5.

[0072] 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 is taken as an example to be a mobile phone, and the internet connection terminal 100 is taken as an example to be a television with internet connection functionality.

[0073] First, the user sets the type of television to be used for browsing the Internet (described later) on a predetermined setting screen on the mobile phone in advance by specifying the manufacturer and model number using, for example, input unit 102 (step 501). Data storage unit 303 stores the input model number and other numbers, operations performed by the user, and signals and information to be transmitted in association with each other. 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.

[0074] The user turns on the television through a predetermined operation, and the television receives and plays back 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 uses the television alone, and this state is referred to as the television's normal mode. The power-on state refers to a state in which at least the main power is on.

[0075] The user performs an operation to start displaying a predetermined 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, allowing the user to view the Internet site (step 502).

[0076] The steps 501 and 502 are the state when the user uses the mobile phone by itself, and this state is the normal mode of the mobile phone.

[0077] Suppose that while browsing the Internet site, the user wishes to view the same Internet site on a television. In this case, the user operates 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 a display switching mode, which is a state for switching the display of the Internet site to a television.

[0078] When the mobile phone enters the display switching mode, system control unit 301 of the mobile phone transmits the URL of the internet site being displayed to the television via data transmission / reception unit 306 (step 504). After transmitting the URL, or simultaneously with transmitting the URL, system control unit 301 controls display unit 305 and the like 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, together with the URL, instructing the television to display the internet site.

[0079] 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 in 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.

[0080] On the other hand, after transmitting the URL, the mobile phone is configured so that the system control unit 301 can operate a television (described later) using some of the keys on the input unit 102, and this state is called the operation switching mode. The display unit 305 displays, for example, as shown on screen display 404, a message explaining to the user the contents of the operations that can be performed by pressing the keys (step 505).

[0081] Here, the configuration capable of operating the television means that, by pressing some keys on input unit 102, data indicating an operation for the television can be transmitted, which can identify the type of television set in step 501, and this data has the same content 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 a selection item on an Internet site displayed on the television or confirming a selection item, the user presses a key on input unit 102 of the mobile phone that corresponds to the operation content shown on screen display 404, and information and signals indicating the operation instruction are transmitted 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. The operation of this step is also performed, for example, by control 301.

[0082] The television receives the information and signals indicating the operation instructions from the mobile phone via the data transmitter / receiver 210, and reflects the contents of the instructions in the screen of the screen display 406 that displays the Internet and in the operation of the Internet browser 208 under the control of the system controller 201 (step 517).

[0083] When the user wishes to return from browsing an internet site on the television to browsing the internet site on the mobile phone, the user selects button display 405 displayed on display unit 305 of the mobile phone (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 transmitter / receiver 306 (step 508). Furthermore, after transmitting the URL, or simultaneously with transmitting the URL, system control unit 202 controls display unit 206 and the like to terminate the display of the internet site on the television.

[0084] The television, which has received the data via the data transmission / reception unit 210, stops displaying the internet site (step 518). Furthermore, the television 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, for example, as shown in screen display 403 (step 520). In step 520, the television returns to a state in which it can operate independently 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.

[0085] 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, so the mobile phone enters display switching mode. The operation of this step is performed, for example, under the control of control unit 301. The operation of this step also resumes display of the internet site on the mobile phone.

[0086] 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 normal mobile phone (step 511). Also, 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 step 512, the mobile phone returns to a state where it can operate on its own again, and so goes into normal mode.

[0087] 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 further operates the internet connection terminal 100 that displays the internet site using the mobile terminal 101.

[0088] 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 a normal mode in which the mobile terminal 101 operates alone to a display switching mode in which the display is switched to the Internet connection terminal 100, and then to an operation switching mode in which the Internet connection terminal 100 is operated by the mobile terminal 101. Also, when displaying the Internet on the mobile terminal 101 again, simply pressing the button once to view the Internet on the mobile terminal 101 ends the operation switching mode, transitions to the display switching mode, and then returns to the normal mode, a series of operations are performed.

[0089] This allows the user to display the internet site on a larger screen by simple operations using only the mobile terminal 100 without operating the terminal on which the new internet site is to be displayed, and further allows the user to continue using the mobile terminal 100 to operate the terminal on which the new internet site is displayed, and the user can smoothly switch the display of the internet site between different terminals.

[0090] 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 in part of the screen.

[0091] 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 is switched 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.

[0092] In addition, 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 under the following circumstances.

[0093] 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 cases where viewing using a television or other display needs to be suddenly interrupted. Specifically, this occurs when multiple people are watching television and it becomes difficult for individuals to view Internet sites.

[0094] In this case, if the user wants to continue viewing an internet site or the like on the mobile terminal 100, one possible approach would be to turn off the TV screen displaying the internet site, start up the browser on the mobile phone with communication capabilities, and input the URL that was displayed on the screen into the mobile phone, thereby continuing viewing on the mobile phone with communication capabilities. However, this method has the problem of requiring a large number of steps for operation.

[0095] In contrast to this, 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 can also be conveniently switched from the internet connection device 100 to the mobile terminal.

[0096] In this embodiment, an internet site has been described as an example of content information, but this is not limiting and information indicating other content, such as a television program, may also be used. Also, a URL has been described as an example of identification information, but this is not limiting. For example, information indicating a television program channel may also be used as identification information. [Example]

[0097] Next, a description will be given of a second embodiment. In this embodiment, a method will be described in which the Internet connection terminal 100 and the mobile terminal 101 of the first embodiment use infrared communication for communication used for sending and receiving URLs and instructions for various operations to realize operations equivalent to those of the first embodiment.

[0098] The present embodiment will be described below with reference to the drawings. In the following, the same reference numerals are used to designate the same components as those in the previous embodiment, and their description will be omitted to avoid duplication.

[0099] The internet connection terminal 100 of the second embodiment shown in FIG. 6 differs from the first embodiment shown in FIG. 2 in that the data transmission / reception unit 210 is an infrared transmission / reception unit 600, and the infrared transmission / reception unit 600 transmits and receives data using, for example, an infrared command communication format specified by the manufacturer or infrared communication conforming to the IrDA standard.

[0100] The mobile terminal 101 of the second embodiment shown in FIG. 7 differs from the mobile terminal of the first embodiment shown in FIG. 3 in that the data transmitter / receiver unit 306 is an infrared transmitter / receiver unit 700, which transmits and receives data using, for example, infrared signals conforming to the IrDA standard.

[0101] The operation of this embodiment will be described below with reference to the flowcharts of Figures 6, 7 and 8. In this embodiment, when the URL of an internet site is transmitted by infrared communication from the mobile terminal 101 in response to a user operation while the internet connection terminal 100 is receiving and playing back digital broadcasting, 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.

[0102] 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 in box 500 and the operation of internet connection terminal 100 in 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, 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 function will be used as an example of internet connection terminal 100.

[0103] First, the user sets in advance on a predetermined setting screen on the mobile phone the type of television to be used for browsing the Internet (described later) by specifying the manufacturer and model number using, for example, 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 for each manufacturer and is a format used for communication with the attached remote control.

[0104] The user turns on the television through a predetermined operation, and the television receives and plays back the broadcast received from the digital broadcast receiving unit 200 according to the mechanism described above (step 514).

[0105] The user performs an operation to start displaying a predetermined 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, allowing the user to view the Internet site (step 502).

[0106] Suppose that while browsing the Internet site, the user wishes to view the same Internet site on a television, in which case the user performs an operation to select button 402 displayed on display unit 305 of the mobile phone (step 503).

[0107] As a result of this operation, infrared transceiver 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). The television, upon receiving this infrared command, starts IrDA communication (step 801) and requests an IrDA communication connection from the mobile phone (step 802). Meanwhile, immediately after transmitting the infrared command in step 800, the mobile phone prepares to start the IrDA connection, responds to the IrDA communication connection request from the television, and an IrDA communication connection between the television and the mobile phone is established (step 803). In addition, after transmitting the URL, or in conjunction with transmitting the URL, system control unit 301 controls display unit 305 and the like to end the display of the Internet site on mobile terminal 101.

[0108] When the IrDA communication connection is established, the system control unit 301 of the mobile phone transmits the URL of the internet site being displayed to the television via IrDA communication by the infrared transmitting / receiving unit 700 (step 504).

[0109] The television receives the URL from the mobile phone via infrared transmitter / receiver 600 (step 515). The television then transmits data indicating successful reception of the URL to the mobile phone via IrDA communication using infrared transmitter / receiver 600 (step 804). When the mobile phone receives the data indicating successful reception of the URL (step 805), it disconnects the IrDA communication using infrared transmitter / receiver 700 (step 806). This disconnection also causes the television to terminate IrDA communication using infrared transmitter / receiver 600 and enter a state in which it can accept normal infrared commands from a remote control (not shown) or the like. The television then connects to the Internet site indicated by the URL using the procedure described above, and displays the Internet site on display 206, as shown in screen display 406 (step 516).

[0110] On the other hand, after transmitting the URL, the mobile phone uses some of the keys on the input unit 102 to configure the mobile phone to operate a television (described later), and displays on the display unit 305 a display explaining to the user the operations that can be performed by pressing the keys, as shown in 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 for operating a television that can identify the type of television set in step 501 is transmitted via the infrared transmitting / receiving unit 700, and the infrared command has the same content as the infrared command transmitted from a remote control (not shown) for 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 on an internet site displayed on the television or deciding on a selection item, the user presses a key on the input unit 102 of the mobile phone that corresponds to the operation shown in screen display 404, and transmits an instruction for the operation from the mobile phone to the television (step 506).

[0111] The television set that has received the operation instruction from the mobile phone reflects the content of the instruction on the screen of screen display 406 that displays the Internet and in the operation of Internet browser 208 (step 517).

[0112] When the user wishes to return from browsing an Internet site on the television to browsing the Internet site on the mobile phone, the user selects button display 405 displayed on display unit 305 of the mobile phone (step 507). This operation causes the mobile phone to send an infrared command to the television via infrared transmitter / receiver unit 700, indicating that the Internet display is to be terminated (step 508).

[0113] Upon receiving the infrared command, the television stops displaying the Internet site (step 518). Furthermore, the television starts IrDA communication 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 starts IrDA communication, receives the IrDA communication connection request from the television, and an IrDA communication connection is established (step 809).

[0114] Upon establishing the communication connection, the television transmits the URL of the Internet site last displayed on the television to the mobile phone via 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 infrared transceiver 600, and becomes ready to 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 in screen display 403, for example (step 520).

[0115] Meanwhile, the mobile phone, which has received the URL of the Internet site last displayed on the television, ends 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). Also, 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).

[0116] In this way, the URL of the internet site to be viewed on mobile terminal 101 is transmitted to internet connection terminal 100 by infrared communication, the internet site is displayed on internet connection terminal 100 that has received the URL, and the user operates internet connection terminal 100 that is displaying the internet site using mobile terminal 101. When transmitting these URLs and operation instructions, the television can be operated using a mobile phone by switching between communication using infrared commands received from a remote control or the like and communication using IrDA, as described above.

[0117] This allows the user to display the internet site on a larger screen by simple operations using only the mobile terminal 100 without operating the terminal on which the new internet site is to be displayed, and further allows the user to continue using the mobile terminal 100 to operate the terminal on which the new internet site is displayed, and the user can smoothly switch the display of the internet site between different terminals.

[0118] In the configuration of this embodiment, IrDA communication is used when transmitting the URL, but the communication method is not limited to IrDA communication and other communication means may be used.

[0119] Furthermore, in this embodiment, examples of the Internet connection terminal 100 include a television device, a set box device, and a DLNA-compatible server, and applying this embodiment to these devices can solve the problems that arise under the circumstances described below.

[0120] For example, general-purpose infrared commands used in television devices are limited in the types of commands that can be sent and received, or have limitations on communication speed. Meanwhile, 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 general-purpose infrared commands are used, 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.

[0121] On the other hand, when performing communication conforming to IrDA, it is necessary to establish communication between the mobile terminal 101 and the Internet connection terminal 100 in order to send and receive information. For this reason, unless communication is switched from general-purpose commands to IrDA, the information processing device must always be in a state of waiting for communication by IrDA. If the connection is always kept in an established state, a problem occurs in which the Internet connection terminal 100 cannot perform infrared communication with other devices.

[0122] In contrast to this, in this embodiment, communication is switched using a general-purpose infrared command as a trigger, so the above-mentioned problem can be eliminated and usability can be improved.

[0123] Although the present embodiment has been described using IrDA communication as an example, it is also possible to use Bluetooth communication, wireless communication such as wireless LAN, short-range communication such as sound wave communication, etc. This embodiment is particularly useful when communication is performed using a communication method that requires the establishment of a communication link to send and receive information.

[0124] In this embodiment, an internet site has been described as an example of content information, but this is not limiting and information indicating other content, such as a television program, may also be used. Also, a URL has been described as an example of identification information, but this is not limiting. For example, information indicating a television program channel may also be used as identification information. [Example]

[0125] Next, a description will be given of a third embodiment. In this embodiment, when transmitting and receiving a URL or various operation instructions in the internet connection terminal 100 and the mobile terminal 101 of the first embodiment, a method will be described in which the internet site indicated by the URL is not simply displayed, but 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.

[0126] Here, the display state refers to, for example, a state in which a screen after login is displayed on the mobile terminal 101 for an internet site that requires authentication. Also, the display state refers to, for example, a display state after a change in an internet site where the display state of the content changes dynamically while the URL remains the same.

[0127] The information indicating the display state may include, 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 and that affects the display on the display screen 305 when browsing an internet site. The information indicating the display state may also include information indicating character encoding such as Shift-JIS, EUC, or UTF-8. For example, a cookie may also be used as the information indicating the display state. The information indicating the display state may also be information indicating the position of a pointer or scroll bar that was displayed on the display unit 305 when the display was switched when an internet site was 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 of the pointer on the internet connection terminal 100 even if the sizes of the display areas of the mobile terminal 101 and the internet connection terminal 100 are different.

[0128] This embodiment will be described below with reference to the drawings. In this description, an example will be described in which an internet site that involves authentication processing is handed over from a mobile terminal 101 to an internet connection terminal 100. In the following, the same reference numerals will be used to designate parts equivalent to those in the previous embodiment, and their description will be omitted to avoid duplication.

[0129] Figure 9 shows an example of the data components and contents 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 a user browses the internet site in this embodiment, and the mobile terminal 101 stores the operation history 900 in the data storage unit 303.

[0130] The information included in this operation history 900 may include, for example, character strings entered in text boxes, information indicating buttons or icons clicked on an Internet site, and information indicating content selected in a list box. The information included in operation history 900 may also include information indicating URLs displayed as a result of such operations.

[0131] 10 shows an example of the data components and contents of an operation history 1000 of user operations on Internet content recorded by the mobile terminal 101 when the user browses the 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.

[0132] FIG. 11 shows transmission data 1100 that the mobile terminal 101 sends to the internet connection terminal 100 in this embodiment, and the transmission data 1100 is composed of header data 1101 containing identification information such as the data length and data type, an internet site URL 1102, and an operation history 900.

[0133] The operation of this embodiment will be described below with reference to the flowcharts of 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 browsed by the user is an internet site that involves authentication processing or internet content whose content changes dynamically without changing the URL. Furthermore, in the same manner as in the first embodiment, when the mobile terminal 101 transmits the URL of the internet site to the internet connection terminal 100, it transmits transmission data 1100 that includes the URL and the operation history 900. Furthermore, 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 in the operation history 900 on the displayed internet site, and displays the internet site in a state where the operation has been completed.

[0134] Fig. 12 adds steps shown in bold frames to the flowchart of Fig. 5 used in Example 1 of the present invention. As with Fig. 5, Fig. 12 shows the operation of mobile terminal 101 in box 500 and the operation of internet connection terminal 100 in box 513, and in the following explanation, the operation flow in box 500 and the operation flow in box 513 will be explained in parallel. In other words, the operation flow of each of mobile terminal 101 and internet connection terminal 100, and the relationship between the operation flows of both terminals will be explained simultaneously. 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 function.

[0135] In this embodiment, when 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 data storage unit 209 (step 1201).

[0136] At this time, the mobile phone does not need to record operation history 900 and operation history 1000 for all internet sites viewed by the user, and may record operation history 900 and operation history 1000 only for internet sites where security is important, for example, where the URL begins with HTTPS (Hypertext Transfer Protocol Security), where the internet site is dynamically generated using a function such as ASP (Active Server Pages), or where the document configuration information of the displayed internet site includes interactive content such as so-called FLASH (registered trademark).If the internet site includes FLASH or ASP content, the content is defined by tags in the source file, and the mobile phone can determine the type of site from these tags.

[0137] 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 in 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 inputs performed on the dynamic content.

[0138] Next, in this embodiment, in step 503, when the user attempts to view the Internet site on the television and selects a button corresponding to button display 402 displayed on display unit 305 of the mobile phone, the mobile phone creates transmission data 1100 including URL 1102 of the Internet site that was the starting point for recording operation history 900 or operation history 1000, and operation history 900 or operation history 1000, and further including header data 1101, and transmits transmission data 1100 to the television. Furthermore, after transmitting the URL, system control unit 301 controls display unit 305 etc. so as to terminate display of the Internet site on the mobile terminal.

[0139] Meanwhile, when the television receives the transmission data 1100 (step 1203), it accesses the internet site of 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).

[0140] In steps 509 and 519, when a URL is sent from the television to the mobile phone, and the terminal that accesses and displays the Internet site is returned to the mobile phone, the same method as above is used.

[0141] In this way, when the internet site that the user browses on the mobile phone is an internet site 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 the user's operations on the internet site in data storage unit 209. Furthermore, the television transmits to the television transmission data 1100 consisting 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.

[0142] This allows the user 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 that will access the new internet site, even if the internet site being viewed is an internet site that requires authentication processing or is internet content whose content changes dynamically without changing the URL.

[0143] 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 is 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 to reflecting the operations on the mobile phone, but the mobile terminal 101 and Internet connection terminal 100 of this embodiment make it possible to reduce the effort required for such operations.

[0144] Although each embodiment has been described above, other information processing terminals, instead of the mobile terminal 101, can also be used to perform communication via the Internet and smooth switching of access between a plurality of terminals. [Explanation of symbols]
