  Next, the signal 600 transmitted by the mobile phone 100 will be described with reference to FIG. FIG. 6 is a diagram illustrating a configuration of a signal 600 transmitted from mobile phone 100 to television 110. Signal 600 includes a start bit 610, control data 620, and an end bit 630. Control data 620 includes, for example, a terminal management table (memory area 510 to area 530 in FIG. 5) that stores the functions of mobile phone 100. The terminal management table has a device ID (01234456789) for identifying the mobile phone 100.

  When television 110 receives signal 600, CPU 810 extracts control data 620 from signal 600. Further, the CPU 810 extracts a terminal management table from the control data 620. CPU 810 detects a control function of mobile phone 100 based on the table. For example, when the terminal management table having the data structure shown in FIG. 5 is transmitted to the television 110 by the mobile phone 100, the television 110 detects that the mobile phone 100 cannot realize the face authentication function by the camera 440. .

  Next, the television 110 according to the present embodiment will be described with reference to FIG. FIG. 7 is a block diagram showing a configuration of functions realized by television 110. The television 110 includes a weak radio wave reception unit 710, a remote control signal reception unit 720, a network reception unit 730, a content data storage unit 740, a broadcast signal reception unit 750, a control unit 760, a remote control signal transmission unit 770, A network transmission unit 780 and a display unit 790 are provided. The control unit 760 includes a terminal monitoring unit 761, an authentication unit determination unit 762, an authentication information request unit 763, an authentication processing unit 764, and a data processing unit 765.

  The weak radio wave receiving unit 710 receives radio waves transmitted by the mobile phone 100. For example, a signal that is transmitted for the mobile phone 100 to notify the base station of its own presence is received by the weak radio wave receiver 710. When the weak radio wave receiving unit 710 detects reception of the signal, the weak radio wave receiving unit 710 sends a signal indicating the detection to the control unit 760. For example, when mobile phone 100 is in a range defined in advance for television 110 (for example, a few meters from television 110), a signal transmitted by mobile phone 100 is received by weak radio wave receiver 710.

  The remote control signal receiving unit 720 receives a remote control signal transmitted to control the operation of the television 110. The remote control signal includes, but is not limited to, an infrared signal, a signal based on Bluetooth (registered trademark), and the like. When remote control signal receiving unit 720 detects reception of the signal, remote control signal receiving unit 720 extracts the control code included in the signal and sends the code to control unit 760. When control unit 760 performs control based on the code, television 110 performs an operation based on the control code transmitted by the remote control signal.

  The network receiving unit 730 receives a signal transmitted from the service providing server 120 connected to the Internet 130. The network receiving unit 730 is connected to a gateway device (not shown) and receives data transmitted by a known communication protocol. The network receiving unit 730 stores the data in the content data storage unit 740. In another aspect, network reception unit 730 sends control data included in the received data to control unit 760. The control unit 760 executes processing specified by the data item included in the data based on the data. Specific processing is realized by a data processing unit 765 described later.

  Broadcast signal receiving unit 750 receives an input of a television broadcast signal received by an antenna connected to television 110. The broadcast signal receiving unit 750 tunes to a frequency corresponding to the designated channel, receives a signal corresponding to the channel from the broadcast signal, and sends the signal to the control unit 760. When the control unit 760 executes display processing based on the signal, the television 110 displays an image based on the signal on the display.

  In the control unit 760, the terminal monitoring unit 761 uses a mobile communication terminal (for example, the mobile phone 100) in the vicinity of the television 110 (for example, a room in which the television 110 is installed) based on the signal transmitted by the weak radio wave receiving unit 710. It is determined whether or not exists. When the terminal monitoring unit 761 detects that the mobile phone 100 exists within the range, the terminal monitoring unit 761 sends a signal representing the detection result to the authentication means determination unit 762.

  Based on the signal received by television 110, authentication means determination unit 762 identifies the type of authentication means possessed by the mobile communication terminal that is the source of the signal. In one aspect, authentication means determination unit 762 identifies the type of authentication means possessed by the mobile phone based on the weak radio wave transmitted by mobile phone 100. The authentication means includes a camera, fingerprint sensor, character input, voice recognition, etc., but other authentication functions may be used. In another aspect, authentication means determination unit 762 identifies the authentication means included in the remote control signal transmission source based on the data included in the remote control signal transmitted toward television 110. The authentication means determination unit 762 sends the specific result to the authentication information request unit 763.

  The authentication information request unit 763 generates a signal for requesting authentication information based on the result of determination by the authentication means determination unit 762. Authentication information requesting unit 763 sends the generated signal to remote control signal transmitting unit 770. Remote control signal transmitter 770 transmits the signal as a control signal (for example, an infrared signal) transmitted from television 110. When a mobile communication terminal (for example, mobile phone 100) capable of receiving an infrared signal exists in the vicinity of television 110, the signal transmitted by remote control signal transmitter 770 is received by mobile phone 100. Based on the signal, the mobile phone 100 detects that authentication information corresponding to the authentication means it has is requested.

  Based on the output from the remote control signal receiving unit 720, the authentication processing unit 764 determines whether the authentication information included in the signal is valid. More specifically, the authentication processing unit 764 converts the authentication information into a packet, and communicates with the information providing apparatus (for example, the service providing server 120) that requests the authentication information via the network transmission unit 780. The service providing server 120 compares the authentication information transmitted from the television 110 with the authentication information registered in advance in the service providing server 120, and determines whether or not these authentication information matches. If the authentication information matches, the service providing server 120 determines that the access by the television 110 is valid, and transmits the result to the television 110. When the network reception unit 730 receives the result, the control unit 760 uses the authentication information (that is, the authentication information transmitted by the user of the mobile phone 100) included in the signal received by the remote control signal reception unit 720 for access. Data representing legitimate information is generated. Control unit 760 displays a result based on the data on display unit 790.

  The data processing unit 765 executes data processing for displaying an image on the display unit 790 based on data given to the television 110 or using data stored in the content data storage unit 740. . The data processing includes, for example, processing for displaying a screen for requesting transmission of authentication information, processing for changing the image quality of the displayed screen, generation of packet data sent to the network transmission unit 780, and the like. In another aspect, data processing unit 765 generates a control signal transmitted by remote control signal transmission unit 770.

  Remote control signal transmitter 770 transmits a weak radio wave based on the output from controller 760. The signal transmission unit 770 transmits a signal according to, for example, Bluetooth (registered trademark). Note that the signal to be transmitted is not limited to that in accordance with Bluetooth (registered trademark), but may be in another form. For example, an infrared signal may be transmitted.

  The network transmission unit 780 is connected to a gateway device (not shown) and communicates with another information communication device (for example, the service providing server 120) connected to the Internet 130. The network transmission unit 780 generates a packet by adding an IP (Internet Protocol) header or the like to the data output from the control unit 760 and transmits the packet to the Internet 130.

  Display unit 790 displays an image based on the output from control unit 760. Display unit 790 is realized by a liquid crystal display, an organic EL (Electro Luminescence) device, or the like.

  Next, a specific configuration of the television 110 will be described with reference to FIG. FIG. 8 is a block diagram showing a hardware configuration of television 110. The television 110 includes a receiving unit 806, an operation unit 808, a CPU 810, an external input unit 804, a tuner 814, a switching circuit 816, a signal processing circuit 820, a display driver 828, a display 830, an amplifier 836a, 836b, speakers 840a and 840b, and a storage device 860. Tuner 814 is connected to antenna 802. The CPU 810 includes a memory 812. The signal processing circuit 820 includes a separation circuit 822 and an OSD (On Screen Display) circuit 824.

  A signal received by the antenna 802 is sent to the tuner 814. The tuner 814 selects a channel designated based on a command from the CPU 810. The signal selected by the tuner 814 is sent to the switching circuit 816.

  The external input unit 804 receives a signal input from the outside of the television 110. External input unit 804 sends the signal to switching circuit 816.

  The switching circuit 816 switches the signal input source between the tuner 814 and the external input unit 804 based on a command from the CPU 810. A signal output from the switching circuit 816 is input to the signal processing circuit 820.

  The receiving unit 806 receives a control signal for controlling the operation of the television 110. The receiving unit 806 receives, for example, an infrared signal. In another aspect, the receiving unit 806 may receive a signal in accordance with Bluetooth (registered trademark). A signal received by the receiving unit 806 is sent to the CPU 810.

  The operation unit 808 receives an instruction input to the television 110. The operation unit 808 is realized by, for example, a button or a touch panel provided on the front surface of the television 110 casing.

  The communication I / F 870 communicates with another information communication device (for example, the service providing server 120) via the Internet 130 connected to the television 110. Communication I / F 870 sends a signal received from the outside of television 110 to CPU 810. Conversely, the communication I / F 870 sends the data given by the CPU 810 toward the Internet 130.

  CPU 810 executes a predetermined operation for television 110 based on data and programs stored in television 110 in advance and instructions given to television 110 from the outside. More specifically, CPU 810 sends a command for selecting a channel to tuner 814 based on a control signal transmitted by mobile phone 100 functioning as a remote control terminal.

  In another aspect, the CPU 810 causes the switching circuit 816 to switch the signal input source. Further, the CPU 810 communicates with another information communication device via the communication I / F 870 as an information processing device. More specifically, the CPU 810 generates an access request for accessing a specific service site, and forms a communication session with the service providing server 120. When the CPU 810 receives a request for transmitting authentication information from the service providing server 120, the CPU 810 transmits authentication information stored in advance on the television 110. In this case, if authentication information is not stored in the television 110, a request signal for authentication information is generated, and the signal is transmitted as a weak radio wave via the transmission unit 816. When the mobile phone 100 receives the signal, it detects that authentication information is required to access the service site.

  The signal processing circuit 820 separates the image signal output from the switching circuit 816 into a video signal and an audio signal based on a command given by the CPU 810 and outputs the separated image signal. More specifically, in the signal processing circuit 820, the separation circuit 822 separates a broadcast signal including an audio signal and a video signal into a video signal and an audio signal in accordance with a command from the CPU 810. The video signal is input to the OSD circuit 824. The audio signal is sent to the amplifiers 836a and 836b.

  The OSD circuit 824 adds character information and other information to the video signal based on a command from the CPU 810, and outputs a synthesized signal. The image added by the OSD circuit 824 includes, for example, a channel number displayed on the display 830, a message based on data prepared in advance in the memory 812, a URL of an Internet site to which the TV 110 is connected via the Internet 130, Includes the name of the site. The output composite signal is input to the display driver 828.

  The display driver 828 converts the signal given from the OSD circuit 824 into a format conforming to the standard of the display 830 and sends the converted signal to the display 830. Display 830 displays an image based on the signal. The displayed image includes an image based on the television broadcast signal received by the tuner 814, an image based on the data input via the external input unit 804, and an image based on the data received by the communication I / F 870. including.

  The amplifiers 836a and 836b amplify the audio signal sent from the separation circuit 822 based on the command given by the CPU 810, and send the amplified signals to the speakers 840a and 840b, respectively. Speakers 840a and 840b output sound based on the signals.

  Storage device 860 stores data given to television 110 in a nonvolatile manner. The storage device 860 is realized as a fixed storage device such as a hard disk or a flash memory. In another aspect, storage device 860 can be realized as a memory card, a DVD (Digital Versatile Disc), or other removable recording medium. Furthermore, the storage device 860 stores data unique to the remote control terminal that controls the television 110, as will be described later.

  Therefore, with reference to FIG. 9, a data structure of television 110 according to the present embodiment will be described. FIG. 9 is a diagram conceptually showing one mode of data storage in storage device 860. Storage device 860 includes a plurality of memory areas for storing data.

  More specifically, the device ID is stored in the memory area 910. The device ID identifies a remote control terminal that controls the television 110. The site ID is stored in the memory area 912. The site ID identifies a service site operated by an information providing apparatus (for example, the service providing server 120) to which the television 110 is connected via the Internet 130. For example, a URL is used as the site ID, but it may be a number uniquely given by the television 110. The television 110 forms a communication session with the service providing server 120 using the site ID.

  The user ID assigned by the service site is stored in the memory area 914. The password is stored in the memory area 916.

  In the example shown in FIG. 9, when the television 110 is controlled by a remote control terminal having a device ID (01234456789), the television 110 has a site ID (www.abc.co.jp). The user ID is “USER1234”. The password used at that time is “aaaaaa1234”. The television 110 can be controlled by a plurality of remote control terminals. More specifically, data about a remote control terminal (memory area 910) having “acouss-mobile” as the device ID is also retained.

  Authentication data registered in advance for the remote control terminal that controls the television 110 is stored in the memory areas 920 to 924. More specifically, the device ID is stored in the memory area 920. This data may overlap with the device ID stored in the memory area 910. When the remote control terminal having the device ID has a CCD camera or other imaging means and authenticates with a face image, the image data is stored in the memory area 922. The image data may be data after processing the data in addition to the data generated by photographing.

  Further, when other data is used as the authentication information, the data is stored in the memory area 924. For example, when a feature amount is calculated based on photographed image data, the feature amount is stored in the memory area 924 as teaching data. The data items stored as authentication information for each remote control terminal are not limited to those shown in FIG. Further, not all terminals may use the same type of authentication information. For example, one remote control terminal may use authentication information based on image data, and the other terminal may use authentication information based on feature values.

  The storage device 860 further stores a program for causing the television 110 to execute a predetermined process. More specifically, a network communication program for the television 110 to perform communication via the Internet 130 is stored in the memory area 930. A program for the television 110 to communicate with the mobile communication terminal is stored in the memory area 940. For example, the process of transmitting a request for authentication information is realized by this program. Firmware for realizing basic operations (for example, signal processing, image processing, etc.) in television 110 is stored in memory area 950. These programs are stored in advance when the television 110 is manufactured. Further, these programs may be changeable via the communication I / F 870. Alternatively, a new program may be added via the communication I / F 870.

  Next, communication between the television 110 and the mobile communication terminal will be described with reference to FIG. FIG. 10 conceptually shows a configuration of signal 1000 transmitted by television 110. Signal 1000 includes a start bit 1010, a control code 1020, and an end bit 1030.

  Start bit 1010 represents the beginning of signal 1000. Control code 1020 includes a request for the recipient of signal 1000 (eg, mobile phone 100). More specifically, the control code 1020 includes a request for camera authentication. In this case, it is assumed that the mobile phone 100 has a camera. The content of the control code 1020 is defined based on the presence or absence of image data (memory area 922) stored in the storage device 860. For example, when the mobile communication terminal that receives the signal 1000 does not have a camera, the control code 1020 includes a request for a user ID and a password instead of a “request for camera authentication”. End bit 1030 represents the end of signal 1000. In one aspect, the signal 1000 is transmitted by the transmission unit 816 as an infrared signal or a signal in accordance with Bluetooth (registered trademark).

  Next, a control structure of the content output system 10 according to the present embodiment will be described with reference to FIGS. FIG. 11 is a flowchart showing a part of a series of operations executed by mobile phone 100 and television 110.

  In step S1110, the television 110 is in a so-called standby state. More specifically, the television 110 is supplied with power from an outlet. The television 110 is in a state where it can receive a signal transmitted from the remote control terminal, although the main switch is off.

  In step S <b> 1112, mobile phone 100 is in a range where signals from television 110 can be received. In step 1120, mobile phone 100 transmits the table information. This table information includes, for example, data stored in memory areas 510 to 530. When the cellular phone 1000 detects a pressing operation on the operation button 420, the cellular phone 1000 transmits the table information via the remote control signal transmission unit 460.

  When the mobile phone 100 is within a range that can be received by the television 110, the television 110 receives the table information (step S1122). More specifically, the television 110 detects reception of the table information via the receiving unit 806. The received table information is temporarily stored in the memory 812.

  In step S1124, CPU 810 analyzes the table information. More specifically, data items constituting the table information are acquired, and the function of the mobile phone 100 is specified. For example, when table information having data (memory areas 510 to 530) shown in FIG. 5 is transmitted, the mobile phone 100 detects that the camera 1 to the camera 4 and the fingerprint sensor function are provided as authentication means. Further, the CPU 810 detects that an actually usable state (that is, an operation set to be valid) is a still image, a moving image, or a barcode as an authentication means (Control 7-Control 9).

  In step S 1130, CPU 810 of television 110 generates an instruction signal for turning on power of television 110, and transmits the signal via transmission unit 816. In step S1132, mobile phone 100 receives a signal transmitted from television 110 via receiver 404. CPU 410 obtains display information (power ON) included in the signal, and causes display 450 to display an image based on the data.

  In step S1140, CPU 410 determines whether or not there has been a power operation on television 110 based on the signal output from operation button 420. When CPU 410 determines that the operation has been performed (YES in step S1140), control is switched to step S1150. If not (NO in step S1140), CPU 410 switches control to step S1160.

  In step S1150, CPU 410 generates a control code having a command to turn on power of television 110 based on the power ON instruction output from operation button 420, and uses the generated signal as remote control signal transmitter 460. Call through. In step S1152, CPU 410 executes an application program stored in flash memory 444, and executes a program (so-called “remote control application”) for causing mobile phone 100 to function as a remote control terminal of television 110. When this program is executed, the mobile phone 100 can give instructions such as channel selection, volume up / down, etc. as a remote control terminal of the television 110. Further, in a certain aspect, an operation for performing Internet communication via the television 110 can be performed. An example of processing in this case will be described in detail with reference to FIG.

  In step S1154, CPU 810 of television 110 switches a switch that receives power supply based on a control signal transmitted by mobile phone 100 (that is, a signal having a control code for turning on the power). In step S1160, television 110 determines whether there is an instruction to turn on the power based on the output from receiving unit 806 or operation unit 808. This process is continuously executed while the power source of the television 110 is not turned on. If CPU 810 determines that there is an instruction to turn on the power (YES in step S1160), it switches control to step S1162. If not (NO in step S1160), CPU 810 switches control to step S1170.

  In step S1162, CPU 810 switches on the power of television 110 by sending a command to a power switch (not shown). This process is executed when an instruction is input from a remote control terminal other than the mobile phone 100 (for example, a remote control terminal as an accessory of the television 110).

  In step S1170, CPU 810 determines whether or not another device has been connected based on the input given to television 110. Input given to television 110 includes one of a signal received by external input unit 804, a signal received by communication I / F 870, and a remote control signal received by receiving unit 806.

  If CPU 810 determines that another device has been connected (YES in step S1170), it returns control to step S1122. If not (NO in step S1170), CPU 810 ends the process.

  When the process shown in FIG. 11 is executed, the main power supply of the television 110 is turned on and the CPU 810 can execute the process. More specifically, the television 110 can display an image based on a signal acquired from the tuner 854. In another aspect, the television 110 can form a communication session with the information providing server 120 and can communicate with the information providing server 120. On the other hand, the mobile phone 100 can function as a remote control terminal of the television 110 while maintaining the standby state of the phone.

  FIG. 12 is a flowchart showing a series of operations performed between mobile phone 100, television 110, and service providing server 120.

  In step S1210, CPU 410 of mobile phone 100 detects that mobile phone 100 is used as a remote control terminal based on the output from operation button 420 (corresponding to step S1152). CPU 410 generates a control code based on the output from operation button 420 and transmits a signal having the code (for example, an infrared signal, a signal in accordance with Bluetooth (registered trademark)) via remote control signal transmitter 460. The control code includes, for example, a code that instructs the television 110 to access the service providing server 120 via the Internet 130.

  In step S <b> 1212, television 110 detects reception of a control signal transmitted by mobile phone 100 based on the output from receiving unit 806. The CPU 810 obtains a connection request for the Internet 130 from the signal and connects to the service providing server 120 via the communication I / F 870. CPU 810 displays a list of service sites provided by service providing server 120 as a service menu based on data received via communication I / F 870. The service menu is displayed on the display 830.

  In step S1214, CPU 810 detects that the content included in the service menu has been selected based on the reception of the control signal transmitted by mobile phone 100. Upon detecting the selection, CPU 810 generates a packet having data specifying the content and an access request, and sends the packet to the Internet 130 via communication I / F 870. When the packet is received by the service providing server 120, the service providing server 120 determines whether or not the packet sent from the television 110 is from a valid user.

  In step S1216, the CPU (not shown) of service providing server 120 generates a transmission request for a user ID and a password registered in advance to access the content selected by television 110, and requests the request. Send to TV 110. Television 110 detects that the request has been received via communication I / F 870.

  In step S1220, CPU 810 determines whether or not mobile phone 100 has an authentication unit based on table information transmitted in advance by mobile phone 100 (step S1122, memory areas 520 and 530 in FIG. 5). When CPU 810 determines that mobile phone 100 has an authentication means (YES in step S1220), control is switched to step S1300. If not (NO in step S1220), CPU 810 switches control to step S1230.

  In step S1230, the user ID and password are entered as normal inputs. That is, an operation on the operation button 420 is performed by the user of the mobile phone 100. More specifically, in step S1232, mobile phone 100 detects that an input request transmitted by television 110 has been received. The CPU 410 detects this based on data output from the receiving unit 404. In response to the detection, CPU 410 causes display 450 to display a screen prompting input of a user ID and password registered in advance in the selected content (step S1214). In step S1234, based on the output from operation button 420, CPU 410 detects that the user ID and password prompted for input have been input by the user. CPU 410 generates a control signal having the user ID and password, and transmits the control signal via remote control signal transmitter 460.

  In step S 1236, television 110 detects that the control signal transmitted by mobile phone 100 has been received based on the output from reception unit 806. CPU 810 obtains the user ID and password from the signal, and temporarily stores them in memory 812. CPU 810 compares these IDs and passwords to confirm that the user ID and password are transmitted from a communication terminal registered in advance in television 110. When it is confirmed that the user ID and password are valid, the CPU 810 generates a packet based on the data. CPU 810 transmits the generated packet via communication I / F 870. This packet is transmitted to the service providing server 120 based on the IP address.

  When the service providing server 120 receives the packet, the service providing server 120 refers to the registered user ID and password stored in advance in the hard disk, and whether the user ID and password transmitted from the television 110 are valid. Determine whether or not. That is, in step 1240, the CPU of service providing server 120 determines whether or not access by television 110 is legitimate. If the CPU determines that the access is valid (YES in step S1240), the CPU switches control to step S1250. If not (NO in step S1240), the CPU generates data indicating that at least one of the user ID and the password transmitted by television 110 is incorrect, and sends the data to television 110. Send. After that, the television 110 executes again the process specified in step S1220.

  In step S1250, the CPU of service providing server 120 delivers the selected content (step S1214). For example, the service providing server 120 distributes the content data in a stream. In step S1252, CPU 810 displays the content on display 830 based on the content received via communication I / F 870.

  Referring to FIG. 13, in step S1300, a hardware authentication process by an authentication unit included in mobile phone 100 is executed.

  First, in step S1310, CPU 810 of television 110 generates a camera authentication request and transmits the generated signal via transmission unit 816. When the mobile phone 100 is located in a range where a signal transmitted from the television 110 can be received, such a signal can be received. In step S1312, the mobile phone 100 detects that a camera authentication request has been received via the receiving unit 404. The CPU 410 activates the camera authentication application by executing an authentication information acquisition program (memory area 570) stored in the flash memory 444.

  In step S1314, CPU 410 performs a shooting operation by camera 440 based on the shooting instruction given to operation button 420. Image data output from the camera 440 is temporarily stored in the RAM 446. The CPU 410 processes the image signal based on the camera authentication application. More specifically, the CPU 410 executes predetermined processing such as binarization processing of image signals and edge enhancement processing. The CPU 410 compares the data obtained by the processing with the teaching data (memory area 590) acquired in advance as the user of the mobile phone 100, and the acquired image is the image of the valid user. Authentication of whether or not.

  In step S1320, CPU 410 determines whether or not the user who has taken the image is the person registered in advance in mobile phone 100. When CPU 410 determines that the user is the user (YES in step S1320), CPU 410 transmits a signal representing the authentication result via remote control signal transmitter 460. In this case, the process is switched to step S1330. On the other hand, when CPU 410 determines that the user is not the user (NO in step S1320), CPU 410 switches control to step S1370.

  In step S1330, CPU 810 of television 110 receives the user ID and password for the service of mobile phone 100 stored in storage device 860 based on the reception of the authentication result via receiving unit 806. Extracted and stored in the memory 812. The CPU 810 converts the user ID and password into a packet and transmits the packet to the service providing server 120 via the communication I / F 870.

  The packet transmitted by the television 110 is received by the service providing server 120. In step S1340, the CPU of service providing server 120 compares the received user ID and password with the user ID and password already registered in service providing server 120, so that access by television 110 is valid. Authentication of whether or not it is a thing. If the CPU determines that the access is valid (YES in step S1340), it switches control to step S1350. If not (NO in step S1340), the CPU generates a packet representing the result and transmits the packet to television 110. When the television 110 receives the packet, it transmits a signal representing the contents of the packet to notify the mobile phone 100 that the authentication has failed. Note that the signal is generated based on data stored in advance in the television 110. Alternatively, a new packet in which a new header is added to the actual data portion of the packet may be transmitted.

  In step S1350, service providing server 120 reads the content requested for distribution from the storage device and transmits the content to television 110, for example, as stream data. The television 110 receives the data via the communication I / F 870 and displays a video based on the data on the display 830 (step S1360).

  In step S1370, mobile phone 100 executes other processing. More specifically, predetermined processing is executed when the user who has performed the operation is not the owner of the mobile phone 100. As an example, the mobile phone 100 blocks the input of a command to the CPU 410 so as to prohibit subsequent operations.

  As described above, according to the content output system according to the present embodiment, the information for specifying the authentication means (camera, fingerprint sensor, character input unit, voice input unit) included in the mobile communication terminal constituting the system. Is transmitted to the content output device constituting the system. Based on the information, the content output apparatus transmits an input request for authentication information necessary for authentication by the service site requested to be accessed by the mobile communication terminal to the mobile communication terminal.

  In the case of a camera-equipped mobile phone, the authentication information can be image data. In the case of a mobile phone with a fingerprint sensor, it may be fingerprint information. Alternatively, it may be a user ID and password input using an operation button of the mobile phone. In other aspects, information representing a voiceprint may be used.

  Further, when the mobile phone 100 includes a non-contact type IC or the like and can implement a wireless ID function, the authentication information may be information stored in the IC or other memory.

  The mobile communication terminal transmits any of such authentication information. The television 110 transmits the received authentication information to the service providing server 120 that operates the service site. The service providing server 120 determines whether or not access to the service site is possible by comparing the received authentication information with data registered as a user of the service site. As a result of the determination, if it is confirmed that the user is a valid user, the television 110 can receive distribution of content information and other services from the service providing server 120.

  In this way, the user of the mobile phone 100 does not need to always store authentication information for accessing the service site. Authentication by the service site is also facilitated. In addition, the television 110 can easily identify an individual. The means for authentication may differ depending on the function of the mobile communication terminal, but according to the content output system 10 according to the present embodiment, it depends on the authentication function of each terminal without depending on the mobile communication terminal. Authentication is realized.

<Modification>
Hereinafter, modifications of the present embodiment will be described. The content output system according to the present modification has the above-mentioned content output system in that the television 110 connected to the network has a function of performing authentication processing based on image data and accessing the service providing server 120 based on the result. Different from 10. Note that the mobile communication terminal and the content output device that constitute the content output system according to the present modification are realized by the mobile phone 100 and the television 110 described above as an example. Therefore, a content output system according to this modification will be described using the configurations of the mobile phone 100 and the television 110.

  With reference to FIG. 14, the control structure of the content output system according to the present modification will be described. FIG. 14 is a flowchart showing a series of operations of hardware authentication processing.

  At step S1410, CPU 810 of television 110 generates a camera authentication request based on the result of determination that mobile phone 100 has an authentication means (YES at step S1220), and transmits the signal via transmitter 816. To send. The mobile phone 100 receives the signal via the receiving unit 404.

  In step S1412, the mobile phone 100 starts the camera authentication application by executing the authentication information acquisition program (memory area 570) stored in the flash memory 444. In step S1414, CPU 410 drives camera 440 to photograph the subject, and executes authentication processing based on the image signal obtained by the photographing. More specifically, it is confirmed whether or not shooting has been performed in a predetermined manner for authentication on the television 110.

  In step S1416, CPU 410 transmits image data obtained by photographing via remote control signal transmitter 460. This signal is received by the receiving unit 806 of the television 110.

  In step S1418, CPU 810 of television 110 compares the image data received via receiving unit 806 with image data registered in advance in storage device 860. If CPU 810 determines that the sender of the image data is registered in advance in television 110, CPU 810 switches control to step S1420.

  More specifically, the CPU 810 reads the user ID and password stored in association with the image data from the storage device 860 and stores them in the memory 812. The CPU 812 generates a packet using the user ID and password, and transmits the generated packet to the Internet 130 via the communication I / F 870. The service providing server 120 receives the packet from the television 110.

  In step S1430, CPU of service providing server 120 requests access to the service site based on the user ID and password received from television 110 and the user ID and password registered in advance in the service providing server. Authentication is performed to determine whether or not the user is a valid user. If the CPU determines that the user is valid (YES in step S1430), the CPU switches control to step S1440. If not (NO in step S1430), CPU generates a packet indicating that the result of the authentication and the transmitted user ID and password cannot be accessed, and transmits the packet to television 110.

  In step S1440, service providing server 120 reads the content requested to be distributed from the content stored in the hard disk (not shown), and generates stream data. The CPU transmits the data to the television 110 via the Internet 130. In step S1450, television 110 displays the content on display 830 based on the data received via communication I / F 870.

  As described above, according to the content output system according to the present modification, the television 110 authenticates the sender of the data based on the data (image data) sent from the mobile phone 100. If it is determined that the user of the mobile phone 100 is valid as a result of the authentication, the user ID and password stored in the television 110 for the mobile phone 100 are transmitted to the service providing server 120.

  The service providing server 120 determines that the access using the user ID and password is valid, and implements the requested service (for example, distribution of content information).

  Here, functions implemented by the content output system according to the present embodiment will be described with reference to FIGS. 15 to 17 are diagrams showing the flow of data in the content output system.

  As shown in FIG. 15, the mobile phone 100 can transmit a remote control signal for controlling the television 110. Using this signal, a device ID for identifying the mobile phone 100 and a table for specifying the functions of the mobile phone 100 are transmitted. If the authentication performed between the mobile phone 100 and the television 110 is successful, the authentication information is transmitted to the service providing server 120 via the Internet 130. With such a configuration, in an existing service using broadband, the user of the mobile phone 100 does not need to store an ID and a password unique to the service. According to the content output system 10 according to the present embodiment, authentication of the person can be realized easily and reliably.

  More specifically, as shown in FIG. 16, when a communication session is formed between the service providing server 120 and the television 110 in one aspect, a service site provided by the service providing server 120 is identified. The site ID is transmitted to the television 110. Television 110 transmits a signal having a site ID. The mobile phone 100 extracts the site ID from the signal and stores the site ID.

  The mobile phone 100 stores a user ID and a password that are input when the service site is first accessed. The input at this time is performed by operating means such as a button of the mobile phone 100 or a jog dial. Therefore, the user can input authentication information using a familiar user input interface. Further, the mobile phone 100 stores the site ID in the flash memory 444. The site ID, user ID, and password are stored in association with each other. As a result, when accessing the service site for the second time or later, the user can transmit the user ID and password together with the site ID to the service providing server 120 without inputting the user ID and password again. In this case, in order to increase security, an authentication unit for confirming that the user is the user of the mobile phone 100 is provided.

  More specifically, referring to FIG. 17, the authentication unit authenticates whether or not the user is a valid user. For example, character input, face image acquisition, fingerprint acquisition, retina acquisition, and the like are performed. For example, as shown on a screen 1710, a screen of a specific site is displayed. When the “call ID” icon is selected, in response to the selection, a screen 1720 requesting input of the registered personal identification number is displayed on the mobile phone 100. When the personal identification number is input to the screen, the mobile phone 100 determines whether or not the personal identification number matches the registered personal identification number. If these passwords match, the mobile phone 100 transmits a signal having the user ID and password. When the television 110 receives the signal, it transmits the user ID and password to the service providing server 120 specified by the site ID.

  As a result, the user does not need to input a user ID and password every time the service site is accessed. In addition, there is no risk of erroneous input, and convenience is provided.

  In other words, according to mobile phone 100 according to the present embodiment, authentication information stored in mobile phone 100 can be used. As a result, for example, even if the family does not have the same mobile phone, each authentication information stored in each mobile phone can be used. Further, even if the specification of the mobile communication terminal is changed due to a change in the model of the mobile phone, the authentication information can be used. As a result, for example, the TV 110 manages personal authentication, so that control according to the family structure of the home can be easily realized. For example, so-called parental lock, viewing restriction of R-designated content, and the like can be realized.

  In addition, when data is input to the mobile phone 100 or a password unique to the mobile phone 100 is input, these data are stored in the mobile phone 100. As a result, since the ID / password stored in the mobile phone 100 can be used when the service site is used next time, the service site can be easily used without inputting data or characters again. As a result, operability or convenience can be improved.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention is applicable to, for example, a television receiver or other video display device, an audio output device, a mobile phone, a PDA, or other information communication terminal. In another aspect, an authentication function using a mobile phone can be applied to an entrance management system. In addition, since the television can grasp the user to be used, it can be applied to the Internet video distribution field in which the advertisement of the program is replaced for each user in the program distribution using the network.
