Description

[Technical field]

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

[0002] Mobile phones that can browse Internet sites and TV programs are becoming more and more common. Meanwhile, televisions that can connect to networks are also becoming more and more common. In this environment, technologies that allow users to conveniently view the same content on their televisions as they view on their mobile phones, and technologies that allow users to use their mobile phones as remote controls to operate televisions, are being considered.

[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 have watched while out again on a large screen after returning home, or to watch part of a program in your free 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 obtained information 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 sending and receiving information to and from 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, characterized in that the video conference system has an information display means that displays a first videophone screen that displays the information in text on a first display of the mobile phone, and displays a second videophone 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 image 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 number 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 previously watched (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 when returning home, or watching part of a program in some free time while out and then watching the rest, the parts before or after that, or the whole program from start to finish on an indoor recording and playback device when returning 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 the viewing.

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

[0011] According to the mail 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 mail terminal described in Patent Document 2, when the user wishes to view an Internet site on the information processing device side, the user must operate the information processing device. This poses the problem of many operational steps.

[0012] Patent Documents 3 and 4 do not mention 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 needs to 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] Thus, there is no description of how to smoothly carry out a linked operation when the viewing of content currently being viewed on a mobile terminal is to be handed over to a video playback device.

[0014] In consideration of the above problems, the present invention has an object to provide a mobile terminal, an information processing device, a content display system, and a content display method that enable smooth handover of content viewing on a mobile terminal 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. Effect 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.

[0030] The video processing unit 205 is configured with a processing device such as an ASIC, an FPGA, an 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 composed of a display device such as a liquid crystal display, a plasma display, etc. The display unit 206 is composed of a display panel, a panel control circuit, and a panel control driver, and displays an image composed of data supplied from the image processing unit 205 on the display panel. 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, a video signal composed of an RGB format or the like is output to an external display device.

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

[0033] The internet browser 208 is software that performs display control and management of content acquired from the internet 104 via the network communication unit 207 in accordance with instructions from the system control unit 202. 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 with a communication device that performs wireless communication with an external terminal such as the mobile terminal 101 in compliance with standards such as Bluetooth and wireless LAN. The data transmitter / receiver 210 outputs data and signals obtained through the 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 response to a request from a system control unit 301 (described later). The communication unit 300 is configured by, for example, a transmitting / receiving device such as a front-end module.

[0039] The system control unit 301 is composed of 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] The internet browser 302 is software that manages and controls the display of content acquired from the internet 104 via the communication unit 300 and the 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 out 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 acquired by the URL input unit 102, the communication unit 300, or the data transmission / reception unit 306, which will be described later.

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

[0042] The video processing unit 304 is configured with 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 composed of, for example, a display panel, a panel control circuit, and a panel control driver, and displays an image composed of 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 compliance with standards such as Bluetooth (registered trademark) and 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 an 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 configurations 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 state 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 in the display unit 305 of the mobile terminal 101, and displays the relationship between the operation performed by the button display 402 and the button related thereto. The same is true for button display 405. In this example, when the user uses the input unit 102 to press a button corresponding to the selection of 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. The button is usually assigned other functions of a mobile phone, and may be configured to be assigned to the switching process when the 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 when the user is browsing the Internet with the Internet connection terminal 100. Screen display 404 shows an example of a case where 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. Also, while the screen display 404 is displayed, the mobile terminal 101 can operate the Internet connection terminal 100. Screen display 406 shows an example of a case where an Internet site is displayed on the display unit 206 of the Internet connection terminal. Also, the screen display 406 shows a state where the home page of the Internet site displayed on the mobile terminal 101 in the screen state 401 is 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 the button display 405, whereby a process of switching the display of the Internet site described later from the Internet connection terminal 100 to the mobile terminal 101 is performed.

[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 their corresponding buttons, a touch panel type input device may be provided.

[0050] Next, the operation of the Internet connection terminal 100 and the 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 from the mobile terminal 101 via wireless communication by a user operation while receiving and playing a digital broadcast, the internet connection terminal 100 displays the internet site indicated by the URL. After this display, the internet connection terminal 100 accepts operations of the internet connection terminal 100 by the mobile terminal 101.

[0052] First, the operation of the Internet connection terminal 100 for receiving and reproducing digital broadcasting will be described with reference to FIG.

[0053] It is assumed that a user instructs the Internet connection terminal 100 to start receiving and playing back a digital broadcast 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 received by the data transmitter / receiver 210 from the remote control, which instructs the start of receiving and playing the digital broadcast, with predetermined information and notifies the system control unit 202. The system control unit 202 gives instructions to the digital broadcast receiving unit 200, the digital broadcast signal processing unit 201, the audio processing unit 203 and the video processing unit 205 to start receiving 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 an antenna and a 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 and audio signals, and outputs them. In addition, the output timing of each signal is synchronized so that the video and audio signals are output in correspondence with each other.

[0057] The audio processor 203 converts the audio signal received from the digital broadcast signal processor 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] Assume that a user transmits the URL of an internet site to the internet connection terminal 100 by wireless communication using the mobile terminal 101 as described below, using the input unit 102 etc. 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. Having received 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 of 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] 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, in the series of operations described above, if there is data to be temporarily stored in the terminal, the internet browser 208 stores the data in the 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. Following the transmission, the mobile terminal 101 becomes capable of operating the internet connection terminal 100, enabling 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 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 to be displayed immediately after startup via the communication unit 300 and to receive the home page data of the internet site.

[0069] The communication unit 300 communicates with the base station 103 by wireless communication, accesses the Internet 104 via the base station 103, and receives data of 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 a homepage from the received data, converts the image into a video signal suitable for input to the video processing unit 304, and outputs the converted image. 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 the converted image. As a result, the image of the homepage is output from the display unit 305. Furthermore, in the above series of operations, if there is data to be temporarily stored in the terminal, the Internet browser 302 stores the data in the data storage unit 303 as necessary.

[0070] Similarly, the mobile terminal 101 obtains a URL input 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, the details of the operation of using the internet connection terminal 100 and the mobile terminal 101 to display an internet site to be displayed on the mobile terminal 101 on the internet connection terminal 100 and subsequently operating the internet connection terminal 100 using the mobile terminal 101 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 in box 500 and the operation flow in 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 an Internet connection function.

[0073] First, the user sets in advance on the mobile phone the type of television to be used for browsing the Internet (described later) on a predetermined setting screen, for example by specifying the manufacturer and model number using input unit 102 (step 501). Here, the input model number and other numbers, operations performed by the user, and signals and information to be transmitted are stored in association with each other in data storage unit 303. Then, control means 301 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 makes it possible to transmit commands that can be recognized by the television from the mobile phone.

[0074] The user turns on the television by a predetermined operation, and the television receives and plays the broadcast received from the digital broadcast receiving unit 200 by the mechanism described above (step 514). The above step 514 is the state when the user uses the television alone, and this state is called the normal mode of the television. The state where the power is on refers to the state where 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 display unit 305 of the mobile phone to display an Internet site as shown in screen display 401, and the user can view the Internet site (step 502).

[0076] The above steps 501 and 502 are the states when the user uses the mobile phone alone, and this state is referred to as the normal mode of the mobile phone.

[0077] Suppose that while browsing the Internet site, the user wishes to view the Internet site on a television. In this case, the user operates the input unit 102 to select the button 402 displayed on the 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 goes into 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 etc. to end the display of the internet site on the mobile terminal. The mobile phone may also be configured to transmit, together with the URL, a signal to instruct 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 in which 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 display on the television 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, which will be described later, using some of the keys on the input unit 102, and this state is called an operation switching mode. The display unit 305 displays, for example, as shown on screen display 404, a display 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 of 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, and the data has the same content as the data transmitted by the remote control of 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 of an Internet site displayed on the television or deciding on a selection item, the user presses a key of the input unit 102 of the mobile phone that corresponds to the operation content shown on screen display 404, thereby transmitting information or a signal indicating an instruction 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. The operation of this step is also performed, for example, by the control of control 301.

[0082] The television receives information or signals indicating the operation instructions from the mobile phone via the data transmission / reception unit 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 control unit 201 (step 517).

[0083] When the user wishes to return from browsing an Internet site on the television to browsing an Internet site on the mobile phone, the user performs an operation to select 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 by 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.

[0084] The television receiving the data by 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 again operates independently and goes into 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 by the television, accesses the URL of the Internet site, 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 a 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 causes the display of the Internet site on the mobile phone to resume.

[0086] At this time, system control unit 301 changes the functions assigned to some of the keys of 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 in which it can operate by itself again, and so the mobile phone enters the 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 which receives the URL, and the user further uses the mobile terminal 101 to operate the internet connection terminal 100 which is displaying the internet site.

[0088] When the user simply presses a 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 a 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.

[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 be displayed in only a part of the screen.

[0091] In this embodiment, when an Internet site is 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. For this reason, 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 a television device, a set box device, and a DLNA-compatible server. By applying this embodiment to these devices, problems that arise under the following circumstances can be solved.

[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 display such as a television needs to be suddenly interrupted. Specifically, this is the case 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, he or she can, for example, turn off the display screen of the Internet site on the television, start up the browser of the mobile phone with communication functions, and input the URL that was being displayed on the screen into the mobile phone, thereby continuing viewing on the mobile phone with communication functions. However, this method has the problem that it requires a large number of steps in operation.

[0095] In contrast, the mobile terminal 101 and Internet connection device 100 of this embodiment solve the problems described above, 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.

[0096] In this embodiment, an Internet site is described as an example of content information, but the present embodiment is not limited to this, and may be information indicating other content such as a television program. Also, a URL is described as an example of identification information, but is not limited to this. For example, information indicating a television program channel may be used as identification information. EXAMPLES

[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 sending and receiving 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 parts 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 Internet connection terminal 100 of 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 defined by the manufacturer or the like, 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 101 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 infrared signals conforming to the IrDA standard, for example.

[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 from the mobile terminal 101 by infrared communication in response to a user's operation while the internet connection terminal 100 is receiving and playing a digital broadcast, the internet connection terminal 100 displays the internet site, and subsequently accepts operation of the internet connection terminal 100 by the mobile terminal 101 via infrared communication.

[0102] Fig. 8 is obtained by adding steps shown in bold frames to the flowchart of Fig. 5 used in the first embodiment of the present invention. As with Fig. 5, Fig. 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 in box 500 and the operation flow in box 513 are explained in parallel to simultaneously explain 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 is used as an example of mobile terminal 101, and a television with an Internet connection function is 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, for example, specifying the manufacturer and model number using the 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, a format determined for each manufacturer and 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 through 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 display unit 305 of the mobile phone to display an Internet site as shown in screen display 401, and the user can 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 set, in which case the user performs an operation to select button 402 displayed on display unit 305 of the mobile phone (step 503).

[0107] By this operation, infrared transmission / reception unit 700 of the mobile phone instructs the television to start IrDA communication by transmitting an infrared command that can be recognized by the type of television set in step 501 (step 800). The television that receives the infrared command starts IrDA communication (step 801) and requests an IrDA communication connection to the mobile phone (step 802). Meanwhile, immediately after transmitting the infrared command in step 800, the mobile phone prepares to start an IrDA connection, responds to the request for the IrDA communication connection from the television, and an IrDA communication connection between the television and the mobile phone is established (step 803). Furthermore, system control unit 301 controls display unit 305 etc. to end the display of the Internet site on mobile terminal 101 after or at the same time as transmitting the URL.

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

[0109] The television receives the URL from the mobile phone via the infrared transmitter / receiver 600 (step 515). The television then transmits data indicating that the URL was successfully received to the mobile phone via IrDA communication by the infrared transmitter / receiver 600 (step 804). When the mobile phone receives the data indicating that the URL was successfully received (step 805), it disconnects the IrDA communication by the infrared transmitter / receiver 700 (step 806). This disconnection also causes the television to end the IrDA communication by the infrared transmitter / receiver 600, and to enter a state in which it can accept normal infrared commands from a remote control (not shown) or the like. Furthermore, the television connects to the Internet site indicated by the URL using the procedure described above, and displays the Internet site on the display unit 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 of the input unit 102 to configure the mobile phone to be operable to operate the television (described later), and displays on the display unit 305 an explanation to the user of the contents of the operations that can be performed by pressing the keys, for example, as shown in the screen display 404 (step 505). Here, the configuration to operate the television means that, by pressing some of the keys of the input unit 102, an infrared command for operating the television that can be identified as the type of television set in step 501 is transmitted via the infrared transmission / reception unit 700, and the infrared command has the same contents as the infrared command transmitted by a remote control (not shown) of the type of television set in step 501. As a result, when the user wishes to perform an operation such as moving a selection item of an internet site displayed on the television or deciding on a selection item, the user presses a key of the input unit 102 of the mobile phone that corresponds to the operation contents shown in the 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 in 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 an Internet site on the mobile phone, the user performs an operation to select button display 405 displayed on display unit 305 of the mobile phone (step 507). This operation causes the mobile phone to transmit an infrared command to the television via infrared transmission / reception unit 700, indicating the end of the Internet display (step 508).

[0113] The television receiving the infrared command 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] With the communication connection established, the television transmits the URL of the Internet site last displayed on the television to the mobile phone via the infrared transmission / reception unit 600 (step 519). The mobile phone receives the URL (step 509) and transmits data indicating successful reception of the URL to the television by IrDA communication (step 810). The television receives the data (step 811), terminates the IrDA communication by the infrared transmission / reception unit 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 it started displaying the Internet site, for example as shown on screen display 403 (step 520).

[0115] Meanwhile, the mobile phone that has received the URL of the Internet site last displayed by the television ends the IrDA communication (step 813), accesses the Internet site of that URL, and displays it (step 510). At this time, system control unit 301 changes the functions assigned to some of the keys of 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 from screen display 404 to screen display 401, for example, and the user continues browsing the Internet site displayed as screen display 401 (step 512).

[0116] In this way, the URL of the internet site to be viewed on the mobile terminal 101 is transmitted to the internet connection terminal 100 by infrared communication, the internet site is displayed on the internet connection terminal 100 that has received the URL, and the user operates the internet connection terminal 100 that displays the internet site using the mobile terminal 101. In addition, 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] In addition, in this embodiment, it has been stated that examples of the Internet connection terminal 100 include a television device, a set-top box device, and a DLNA-compatible server, and by applying this embodiment to these devices, it is possible to solve the problems that arise under the circumstances described below.

[0120] For example, the general-purpose infrared commands used in television devices are limited in the types of commands that can be sent and received, or the communication speed is limited. On the other hand, signals indicating URLs and operation 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, there is a problem that it is not possible to send and receive URLs and operation 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 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. Therefore, if communication is not switched from general-purpose commands to IrDA, it is necessary to always keep the information processing device in a standby state 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, in this embodiment, communication is switched using a general-purpose infrared command as a trigger, so that the above-mentioned problems can be eliminated and usability can be improved.

[0123] In this embodiment, IrDA communication has been described as an example, but it is also possible to use Bluetooth communication, wireless communication such as wireless LAN, and short-distance communication such as sound wave communication. 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 is described as an example of content information, but the present embodiment is not limited to this, and may be information indicating other content such as a television program. Also, a URL is described as an example of identification information, but is not limited to this. For example, information indicating a television program channel may be used as identification information. EXAMPLES

[0125] Next, a third embodiment will be described. 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 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 will be described.

[0126] Here, the displayed state refers to, for example, a state in which a screen 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, 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, the information indicating the display state may be a cookie. The information indicating the display state may also be information indicating the position of a pointer or the position of a 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 or the like 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 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 involving 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] FIG. 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 in this embodiment, which is recorded by the mobile terminal 101 when a user browses the Internet site, 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 into text boxes, information indicating buttons or icons clicked on an Internet site, information indicating contents selected in a list box, etc. The information included in the operation history 900 may also include information indicating a URL displayed as a result of such operations.

[0131] 10 shows an example of the components and contents of data in operation history 1000 of user operations on Internet content recorded by mobile terminal 101 when a user browses Internet content whose contents change dynamically without changing the URL in this embodiment, and mobile terminal 101 stores operation history 1000 in data storage unit 303. Operation history 1000 includes, for example, information indicating the position of the clicked coordinates.

[0132] FIG. 11 shows transmission data 1100 that the mobile terminal 101 transmits to the Internet connection terminal 100 in this embodiment, and the transmission data 1100 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 the Internet site browsed by the user is, for example, an Internet site involving authentication processing or Internet content whose contents change dynamically without changing the URL. In addition, 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 consisting of the operation history 900 in addition to the URL. 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 by 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 is a flowchart of Fig. 5 used in the first embodiment of the present invention, with the steps shown in bold frames added. As in 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. That is, the respective operation flows of mobile terminal 101 and Internet connection terminal 100, and the relationship between the operation flows of both terminals will be explained simultaneously. Also, in the following explanation, mobile terminal 101 will be taken as an example of a mobile phone, and Internet connection terminal 100 will be taken as an example of a television with an 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 the operation history 900 and the operation history 1000 in the data storage unit 209 (step 1201).

[0136] In this case, the mobile phone does not need to record the operation history 900 and the operation history 1000 for all Internet sites viewed by the user, and may record the operation history 900 and the operation history 1000 only for Internet sites where security is important, for example, where the URL starts with HTTPS (Hypertext Transfer Protocol Security), where the Internet site is dynamically generated by 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 source file is defined by tags, and the mobile phone can determine the type of the site by these tags.

[0137] Also, even if the Internet site is a dynamically generated Internet site, it is not necessary to store all operation histories 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 is the starting point for recording operation history 900 or 1000, operation history 900 or 1000, and header data 1101 added thereto, 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 end the 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 has been performed (step 1204).

[0140] In steps 509 and 519, when a URL is transmitted from the television to the mobile phone, and the terminal for accessing and displaying the Internet site is returned to the mobile phone, the same method as described above is used.

[0141] In this way, when the Internet site that the user browses on the mobile phone is an Internet site that involves authentication processing or is Internet content whose contents change 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 is the starting point for recording operation history 900 and operation history 1000, and operation history 900 and operation history 1000. Furthermore, upon receiving the transmission data 1100, the television accesses the Internet site indicated by the URL, performs the operations indicated by operation history 900 and operation history 1000 on the Internet site, and displays the Internet site in a state in which 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 accessing the new Internet site, even if the Internet site being viewed is an Internet site that requires authentication processing or Internet content whose contents change dynamically without changing the URL.

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

[0144] Although each embodiment has been described above, other information processing terminals other than 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]
