  As the best mode for carrying out the invention, first and second broadcast systems to which the present invention is applied will be described.

  The first broadcast system 1 will be described. FIG. 1 shows a conceptual diagram of the first broadcast system 1.

  As shown in FIG. 1, the first broadcast system 1 includes a broadcast station 2, a television device (hereinafter abbreviated as a TV device) 3, and a mobile terminal 4.

  The broadcast station 2 converts content data composed of television programs, commercials, and the like into broadcast signals, and releases the broadcast signals to the outside. The broadcast signal is distributed to the TV device 3 of each user via a broadcast network (whether wired or wireless). The broadcast signal may be a signal by broadcasting transmission using the Internet or the like as well as wireless broadcasting such as so-called TV broadcasting. In addition, the broadcasting station 2 adds related information related to the content of the content data to the broadcast signal in synchronization with the content. When synchronized and added to a broadcast signal, content data and related information associated with each other are provided to the user at the same time in time. For example, the name of the music performer currently being broadcast, the name of the music, sample data of the music, the name of the movie currently being broadcast, the name of the director, the name of the actor, and the information described in the pamphlet of the movie Information such as the name and price of the product currently being broadcast, the discount coupon, the name of the provider, etc. are included as related information in synchronization with the broadcast signal.

  FIG. 2 shows an internal configuration diagram of the TV device 3 and the portable terminal 4.

  As shown in FIG. 2, the TV apparatus 3 is extracted with a broadcast signal receiving unit 3-1 that receives a broadcast signal, a data separation unit 3-2 that extracts content data and related information from the received broadcast signal, respectively. A content output unit 3-3 that outputs the content data, and an NFC communication device 3-4 that outputs related information by a near field communication method (hereinafter referred to as an NFC (Near Field Communication) communication method). The NFC communication method is a wireless communication method that enables communication at a distance between devices that is equal to or less than a predetermined distance (for example, about 10 cm), and details thereof will be described later.

  The TV apparatus 3 receives the broadcast signal distributed from the broadcast station 2 and separates the received broadcast signal into content data and related information. Then, the TV device 3 outputs the content data from the content output unit 3-3, and outputs related information synchronized with the content data to be output from the NFC communication device 3-4.

  The portable terminal 4 is an information processing apparatus that can be carried by a user. For example, the mobile terminal 4 is a mobile phone, a small computer, or the like. As shown in FIG. 2, the mobile terminal 4 includes an NFC communication device 4-1 that receives related information using the NFC communication method, a storage unit 4-2 that stores the received related information, and a stored related information. And a display section 4-3 for displaying. The mobile terminal 4 receives the related information output from the TV device 3 by the NFC communication method, and stores the received related information in the storage unit 4-2. And the portable terminal 4 displays a relevant information on the display part 4-3 according to a user's operation. Note that the portable terminal 4 may be a card-like storage medium in which information cannot be input or displayed by itself, but only information storage can be performed.

  FIG. 3 shows a processing flow of the first broadcasting system 1, and an information flow in the first broadcasting system 1 will be described.

  In the first broadcast system 1, the broadcast station 2 broadcasts a broadcast signal. The broadcast signal includes content data and related information related to the content data in time synchronization. The TV device 3 receives the broadcast signal transmitted from the broadcast station 2, and outputs the content data and related information included in the broadcast signal (step S11). The related information is continuously transmitted from the NFC communication device 3-4 in the TV device 3 in synchronization with the output of the content data. However, in the case of the NFC communication method, even if information is transmitted from the TV apparatus 3, information is not transmitted unless there is another communication apparatus within the communicable range.

  Here, it is assumed that a user who is viewing the content at a certain timing desires to store related information on the content in his / her mobile terminal 4. At this time, as shown in FIG. 4, the user brings the mobile terminal 4 close to the TV device 3 until it is within the communicable range by NFC communication (step S12). This operation is hereinafter referred to as touch operation. When the touch operation is performed, the related information output from the TV device 3 at that time is transferred to the mobile terminal 4 (step S13). That is, since the related information and the content are synchronized, information related to the content of the content being viewed by the user is transferred to the mobile terminal 4.

  Then, the transferred related information can be referred to by the mobile terminal 4 (step S14). The related information 4 is stored in the mobile terminal 4 and can be referred to by the user later or transferred to another location.

  As described above, in the first broadcasting system 1, the content data and the related data are transmitted from the broadcasting station 2, and the TV apparatus 3 outputs the content data and outputs the related data in synchronization with the content data. Further, in the first broadcasting system 1, related data is transmitted by the NFC communication method.

  Therefore, in the first broadcasting system 1, it is possible to acquire the related information very easily when watching a television broadcast, for example. In particular, in the first broadcasting system 1, since information is acquired from the TV apparatus 3 using the NFC communication method, a natural operation feeling such as directly grabbing information from the TV apparatus 3 that is outputting content. Can be given to the user. Further, in the first broadcasting system 1, since the user does not have to perform a complicated operation, the related information can be acquired immediately, and the user can be made to actively acquire the related information. .

  As shown in FIG. 5, the first broadcast system 1 may include a content server 6. The content server 6 is a device for temporarily storing received broadcast data and shifting the broadcast time. As described above, in the system including the content server 1, content data is stored in the content server 6 and related information is also stored. The content server 6 outputs the time-shifted content data and outputs the related information in synchronization with the content data.

  FIG. 6 explains the flow of information in the first broadcasting system 1 provided with the content server 6.

  In the first broadcast system 1, the broadcast station 2 broadcasts a broadcast signal. The broadcast signal includes content data and related information related to the content data in time synchronization. The content server 6 receives the broadcast signal transmitted from the broadcast station 2 (step S21), and accumulates content data and related information included in the content broadcast signal (step S22).

  After the content data is stored in the content server 6, the TV device 3 reads out the content data and related information from the content server 6 and outputs the content data after a predetermined time (step S23). The related information continues to be transmitted from the NFC communication device 3-4 in the TV device 3 in synchronization with the output of the content data. However, in the case of the NFC communication method, even if information is transmitted from the TV apparatus 3, information is not transmitted unless there is another communication apparatus within the communicable range.

  Here, it is assumed that a user who is viewing the content at a certain timing desires to store related information on the content in his / her mobile terminal 4. At this time, the user brings the mobile terminal 4 close to the TV device 3 until it is within the communicable range by NFC communication (step S24: touch operation). When the touch operation is performed, the related information output from the TV device 3 at that time is transferred to the mobile terminal 4 (step S25). That is, since the related information and the content are synchronized, information related to the content of the content being viewed by the user is transferred to the mobile terminal 4. Then, the transferred related information can be referred to by the mobile terminal 4 (step S26). The related information 4 is stored in the mobile terminal 4 and can be referred to by the user later or transferred to another location.

  In the above example, the content data and the related information are transmitted at the same time. However, the content data is broadcast in real time, and the related data is downloaded and stored together for each program, for example, at the timing of the touch. The related information may be searched and transmitted to the mobile terminal 4.

  Next, an NFC communication apparatus provided in the TV apparatus 3 and the portable terminal 4 and an NFC communication system that is a communication system thereof will be described.

  FIG. 7 shows a configuration example of a communication system that performs communication using the NFC communication method.

  The NFC communication method is a two-way wireless communication method between the two devices 10 and 20, as shown in FIG.

  As shown in FIG. 7, the NFC communication method enables communication when the distance between two NFC communication devices is within a certain distance (communication possible distance) (for example, within 10 cm or within 50 cm). Is a communication method. The communicable distance is a distance that does not reach the distance unless the user actively moves the two NFC communication devices closer to each other. An operation in which a user actively brings NFC communication devices close to each other and a communicable distance also vary depending on functions and properties of devices to which the NFC communication device is applied. For example, if it is applied to a small and lightweight portable device that the user can hold with one hand, the operation of bringing NFC communication devices closer to each other within about 10 cm can be said to be an operation of actively approaching, and a pass gate is used for security. If the user's possession card and the gate security device communicate with each other when passing through, the operation of bringing the devices closer to about 50 cm can be said to be an operation of actively approaching.

  In the NFC communication method, processing is performed such that digital data is modulated and transmitted with respect to an electromagnetic wave of a predetermined carrier wave, the electromagnetic wave is received by an antenna, and the digital data modulated in the received signal is demodulated. Wireless communication system. The NFC communication method may be a half-duplex communication using a common frequency for electromagnetic waves transmitted by two devices, or may be a full-duplex communication by changing the frequency transmitted by the other device. Good. The carrier frequency used in the NFC communication system is, for example, 13.56 MHz in the ISM (Industrial Scientific Medical) band.

  The NFC communication system is also a communication system that enables data transmission in two modes, an active mode and a passive mode. The active mode is a system in which an electromagnetic wave obtained by modulating digital data is transmitted by supplying power to an antenna on the transmitting side, and the receiving side receives the electromagnetic wave. In the passive mode, the receiving side generates a magnetic field of a predetermined frequency (a magnetic field in which information is not modulated) from the loop antenna, and the transmitting side switches the load value of its own loop antenna according to digital data. In this method, digital data is transmitted from the transmission side to the reception side by changing the current flowing through the loop antenna. That is, the passive mode is a mode in which data is transmitted by the load modulation method. In the NFC communication system, the same digital modulation system is adopted in both the active mode and the passive mode, and the demodulator is shared. That is, in the NFC communication system, a digital modulation system (for example, ASK, PSK, QAM modulation, etc.) that can be modulated even in the passive mode is used.

  In the NFC communication method, when transmitting information in the passive mode and receiving information transmitted in the active mode, power is received from the received electromagnetic wave by electromagnetic induction and the internal electric circuit is operated. It is also a communication method that enables this. Therefore, when transmitting information in the active mode, sufficient transmission power is ensured so that sufficient power can be supplied within the communication distance on the assumption that the other party does not have internal power.

  The above are the physical characteristics of the NFC communication system.

  A device to which such an NFC communication system is applied may be any device. For example, an information processing apparatus that can be carried by a user, a personal computer, a large computer, a mobile phone, a notebook computer, and the like. Furthermore, the NFC communication method does not need to have a power supply in one communication device (because it can transmit in passive mode and can supply power based on the received radio wave power). The NFC communication apparatus can be applied to various objects such as storage media, wall-mounted advertisements, hanging advertisements, and the like.

  Next, a specific configuration of the NFC communication apparatus 10 will be described with reference to FIG.

  The NFC communication apparatus 10 includes a loop antenna 11.

  The loop antenna 11 constitutes a closed loop coil. The loop antenna 11 radiates electromagnetic waves to the outside by changing the current flowing through the closed loop. Further, in the loop antenna 11, a magnetic flux density passing through the closed loop is changed by an electromagnetic wave or a magnetic field incident from the outside, so that a current corresponding to the strength of the electromagnetic wave or the magnetic field flows through the closed loop.

  The NFC communication apparatus 10 tunes and detects the current flowing through the loop antenna 11, demodulates the code sequence from the detected signal, and the code sequence demodulated by the reception / demodulation unit 12. And a decoder 13 for performing a decoding process.

  The reception / demodulation unit 12 receives a current flowing through the loop antenna 11 and performs tuning and detection on the received signal. The reception / demodulation unit 12 performs a demodulation process corresponding to a predetermined modulation scheme (for example, ASK, PSK, QAM modulation, etc.) on the tuned and detected signal to generate a code string. The code string output from the reception / demodulation unit 12 is supplied to the decoder 13. The decoder 13 performs decoding processing corresponding to, for example, Manchester code, modified mirror, NRZ, and the like on the input code string to generate reception data, and outputs the generated reception data. The received data is supplied to a data processing unit or the like of a device to which the NFC communication apparatus is applied.

  Further, the NFC communication apparatus 10 encodes input transmission data to generate a code string, an encoder 14 that performs modulation and transmission according to the code string, and a code string according to the code string. A load modulation unit 16 that performs load modulation and a carrier output unit 17 that generates carrier signal power.

  The NFC communication apparatus 10 receives transmission data as data to be transmitted to a transmission partner from a data processing unit or the like of a device to which the NFC communication apparatus is applied. The encoder 14 performs an encoding process corresponding to, for example, Manchester code, a modified mirror, NRZ, or the like on the input transmission data to generate a code string. The generated code string is supplied to the modulation / transmission unit 15 and the load modulation unit 16.

  The modulation / transmission unit 15 modulates a carrier signal of a predetermined frequency based on the input code string by a predetermined modulation method (for example, ASK, PSK, QAM modulation, etc.), amplifies the modulation signal, To drive. Therefore, the modulation / transmission unit 15 can radiate an electromagnetic wave, in which information generated from its own loop antenna 11 is modulated, to the other party's loop antenna and transmit information to the other party.

  The load modulation unit 16 performs load modulation by changing the impedance of the loop antenna 11 when the loop antenna 11 is viewed as a coil based on the input code string. Therefore, if the magnetic field of a predetermined frequency is formed around the loop antenna of the communication partner and the own loop antenna 11 is in the magnetic field, the load modulation unit 16 has the loop antenna of the communication partner. Information can be transmitted to the communication partner by changing the current.

  The carrier wave output unit 17 amplifies a signal corresponding to a carrier wave having a predetermined frequency to drive the current of the loop antenna 11, and causes the loop antenna 11 to emit an electromagnetic wave in which information of the predetermined frequency is not modulated. As a result, a magnetic field having a predetermined frequency is formed around the own loop antenna 11. Therefore, if the communication partner's loop antenna is in the magnetic field and load modulation is performed by the communication partner, the current flowing through the loop antenna 11 of the communication partner changes and information can be received from the communication partner.

  The NFC communication apparatus 10 includes a power supply unit 18 and a control unit 19.

  The power supply unit 18 supplies direct current (DC) voltage to each unit of the NFC communication apparatus 10 and the entire apparatus in which the NFC communication apparatus 10 is provided. When power is supplied from a battery or the like, the power supply unit 18 generates a DC voltage based on the power. When there is no power supply from a battery or the like, the power supply unit 18 detects power from the loop antenna 11 and generates a DC voltage based on the power. That is, when there is no supply of power from a battery or the like, the power supply unit 18 generates a DC voltage based on the power of the electromagnetic wave radiated from the communication partner.

  The control unit 19 controls each block constituting the NFC communication apparatus 10.

  In such an NFC communication apparatus 10, the following operation is performed at the time of transmission and at the time of reception.

  During data transmission in the active mode, transmission data is input to the NFC communication device 10. In the NFC communication apparatus 10, after the input transmission data is encoded by the encoder 14, the loop antenna 11 is driven by the modulation / transmission unit 15. During data transmission in the active mode, the encoder 14 and the modulation / transmission unit 15 operate, and the reception / demodulation unit 12, the decoder 13, the load modulation unit 16, and the carrier wave output unit 17 do not operate.

  During data transmission in the passive mode, transmission data is input to the NFC communication device 10. In the NFC communication apparatus 10, after the input transmission data is encoded by the encoder 14, the impedance of the loop antenna 11 is switched by the load modulation unit 16. At the time of data transmission in the passive mode, the encoder 14 and the load modulation unit 16 operate, and the reception / demodulation unit 12, the decoder 13, the modulation / transmission unit 15 and the carrier wave output unit 17 do not operate.

  The NFC communication apparatus 10 may selectively perform switching between both the active mode and the passive mode, but the apparatus can perform only the active mode transmission operation or the passive mode transmission operation as the transmission operation. It may be. When performing the transmission operation only in the active mode, the load modulation unit 16 has a function that is not necessary. Therefore, the function of the load modulation unit 16 is always stopped, or the load modulation unit 16 is removed. May be. In addition, when performing transmission operation only in the passive mode, the function of the modulation / transmission unit 15 and the carrier wave output unit 17 is not necessary, so the functions of the modulation / transmission unit 15 and the carrier wave output unit 17 are always stopped. Alternatively, the modulation / transmission unit 15 and the carrier output unit 17 may be removed.

  Further, at the time of reception when the communication partner is performing active mode data transmission, a current flows through the loop antenna 11 by the electromagnetic wave radiated from the communication partner. In the NFC communication apparatus 10, the reception / demodulation unit 12 receives and demodulates a transmission signal based on the current flowing through the loop antenna 11, and the decoder 13 decodes the demodulated signal and outputs reception data. At the time of reception when the communication partner is performing data transmission in the active mode, the reception / demodulation unit 14 and the decoder 13 operate, and the encoder 14, the modulation / transmission unit 15, the load modulation unit 16, and the carrier wave output unit 17 operate. Not.

  At the time of reception when the communication partner is performing passive mode data transmission, the carrier wave output unit 17 generates a constant frequency electromagnetic wave (magnetic field) from the loop antenna 11 according to the load modulation of the communication partner. A current flows through the loop antenna 11. In the NFC communication apparatus 10, the reception / demodulation unit 12 receives and demodulates a transmission signal based on the current flowing through the loop antenna 11, and the decoder 13 decodes the demodulated signal and outputs reception data. At the time of reception when the communication partner is performing data transmission in the passive mode, the reception / demodulation unit 14, the decoder 13 and the carrier wave output unit 17 operate, and the encoder 14, the modulation / transmission unit 15 and the load modulation unit 16 operate. Not.

  The NFC communication apparatus 10 may be configured to perform reception corresponding to both the case where the communication partner is in the active mode and the case where the communication partner is in the passive mode. It may be a device that allows the other party to perform only the passive mode operation. When the communication partner performs only the operation in the active mode, the carrier wave output unit 17 becomes a function that is not necessary. Therefore, the function of the carrier wave output unit 17 is always stopped or the carrier wave output unit 17 is removed. It may be configured.

  The NFC communication apparatus and the NFC communication system which is the communication system as described above are applied to the TV apparatus 3 and the mobile terminal 4.

  Next, the second broadcast system 30 will be described.

  As shown in FIG. 9, the second broadcast system 30 includes a broadcast station 32, a TV device 33, a server 34, an external terminal 35, and a mobile terminal 36.

  The broadcast station 32 converts content data composed of television programs, commercials, and the like into broadcast signals, and releases the broadcast signals to the outside. The broadcast signal is distributed to the TV device 33 of each user via the broadcast network 37. Also, the broadcast station 32 adds related information related to the contents of the content data to the broadcast signal in synchronization with the contents. When synchronized and added to a broadcast signal, content data and related information associated with each other are provided to the user at the same time in time.

  FIG. 10 shows an internal configuration diagram of the TV device 33 and the portable terminal 36.

  As shown in FIG. 10, the TV apparatus 33 includes a broadcast signal receiving unit 33-1 that receives a broadcast signal, a data separation unit 32-2 that extracts content data and related information from the received broadcast signal, and an extraction unit. The content output unit 33-3 that outputs the content data that is output, the NFC communication device 33-4 that communicates with the mobile terminal 36 by the NFC communication method, and the related information is uploaded to the server 34 via the network 38 such as the Internet. And a network communication unit 33-5. The TV device 33 receives the broadcast signal distributed from the broadcast station 32 and separates the received broadcast signal into content data and related information. Then, the TV device 33 outputs the content data from the content output unit 33-3. When there is a request for acquiring related data from the portable terminal 36 via the NFC communication device 33-4 while the content data is being output, the TV device 33 synchronizes with the content data currently being output. Information is uploaded to the server 34 via the network 38.

  The server 34 is a data storage device provided on the network 38 and is accessed from the TV device 33 and the external terminal 35 via the network 38. When the related information is uploaded from the TV device 33, the server 34 identifies the ID of the mobile terminal 36 of the user who acquired the related information, and stores the related information for each ID.

  The external terminal 35 is a terminal installed in, for example, a station or a public facility. As shown in FIG. 9, the external terminal 35 includes a data receiving unit 35-1 that downloads related information from the server 34 via the network 38, and an NFC communication device 35-2 that communicates with the mobile terminal 36 using the NFC communication method. And.

  The portable terminal 36 is an information processing apparatus that can be carried by the user, and has the same configuration as the portable terminal 4 of the first broadcasting system 1 shown in FIG.

  When a touch operation is performed on the TV device 33 while the TV device 33 is outputting content data, the portable terminal 36 transmits a related information acquisition request to the TV device 33. When there is a request for acquiring related data from the mobile terminal 36, the TV device 33 uploads related information synchronized with the content data currently being output to the server 34 via the network 38.

  Further, when a touch operation is performed by the mobile terminal 36, the external terminal 35 downloads related information selected by the mobile terminal 36 from the server 34 and transfers it to the mobile terminal 36.

  In the second broadcasting system 30 as described above, related information acquired by the user using the mobile terminal 36 is uploaded on the server 34. Therefore, regardless of the data storage capacity of the portable terminal 36, the user can acquire a lot of related information, and the related information can be acquired as needed even when away from home.

  FIG. 11 shows a processing flow of information acquisition processing on the go in the second broadcasting system 30, and the information flow in the second broadcasting system 30 will be described.

  It is assumed that the user desires the income of related information acquired so far, for example, when going out. At this time, the user brings the mobile terminal 36 close to the external terminal 35 until it is within the communicable range by NFC communication (touch operation: step S31).

  Subsequently, the user presses the ID authentication button of the mobile terminal 36 (step S32). When the ID authentication button is pressed, ID information for identifying itself is transferred from the portable terminal 36 to the external terminal 35, and the external terminal 35 authenticates the ID (step S33). When the authentication is completed, the external terminal 35 downloads all the related information identified by the ID from the server 34 (step S34). Then, the external terminal 35 displays a list of downloaded related information (step S35).

  Subsequently, the user refers to the related information displayed on the external terminal 35 and searches for information that the user desires to transfer (step S36). If there is no relevant information to be transferred, the user ends the process.

  When there is related information desired to be transferred, the user selects information to be acquired using the portable terminal 36 (step S37). Subsequently, the user presses the transfer button of the mobile terminal 36 (step S38). When the transfer button is pressed, the external terminal 35 transfers the selected related information to the portable terminal 36 by NFC communication (step S39). When the related information is transferred to the portable terminal 36, the information is displayed by the portable terminal 36 (step S40).
