(First embodiment)
FIG. 1 is a block diagram of a receiving apparatus according to the first embodiment of the present invention connected to an interphone apparatus.

  In FIG. 1, a receiving system is configured by the receiving device 101 and the interphone device 130 that can be connected to the interphone device 130.

  Hereinafter, the configuration of each processing unit of the receiving apparatus 101 will be described together with the operation.

  A tuner 102 (receiving means for receiving a broadcast signal) receives a digital broadcast signal input via an antenna indicated by L101 or a cable TV line. The descrambler 103 performs demodulation processing and error correction processing on the signal received by the tuner 102 that is input via the signal line L103, and generates a transport stream (TS).

  The decoder 104 decodes (decodes) the video signal, audio signal, and program information output from the descrambler 103 and input via the signal line L104. The synthesizing unit 108 synthesizes the video signals and outputs them to the display unit 109 via the signal line L108.

  The synthesis target is the video signal input from the signal line L124, decoded by the decoder 104 and enlarged / reduced by the scaler 119, and the customer registration screen generation unit 112 input from the signal line L112. This is a video signal of the customer registration screen.

  The visitor registration screen generation unit 112 functions as a visitor registration screen generation unit that generates a visitor registration screen for registering a visitor image and a visitor name in association with each other.

  Further, what is to be synthesized is a video signal input from the signal line L124, decoded by the decoder 104, and enlarged / reduced by the scaler 119, and generated by the visitor screen generation unit 117 input from the signal line L115. This is a video signal of a visitor screen.

  The visitor screen generation unit 117 functions as a visitor screen generation unit that generates a visitor screen based on the visitor information from the intercom device 130 received via the communication unit 113.

  When the user inputs a visitor name on the visitor registration screen generated by the visitor registration image generation unit 112, the input visitor name is stored in the visitor name primary storage unit 120. The visitor name stored in the visitor name primary storage unit 120 is transmitted to the intercom device 130 via the communication unit 113 after the visitor registration screen is completed.

  The display unit 109 is a processing unit that displays the video signal combined by the combining unit 108 input from the signal line L108 using a display device such as an LCD (Liquid Crystal Display) or a PDP (Plasma Display Panel).

  The program information analysis unit 107 analyzes the program information decoded by the decoder 104 that is input via the signal line L106. The program end detection unit 106 detects the program end time currently being viewed from the program information input by the signal line L107 and analyzed by the program information analysis unit 107.

  The program information analyzed by the program information analysis unit 107 is an event information table (EIT: Event Information Table) in which an event (program) name (event_id), a broadcast start time (start_time), a program duration (duration), and the like are described. )including.

  The program end detection unit 106 detects the program end by determining the program end time from the value obtained by adding the program duration to the program start time in the event information table.

  The remote control receiving unit 105 is a receiving unit for receiving a remote control code input from a signal L102 such as an infrared signal. The remote control code analyzing unit 110 is a processing unit for acquiring the signal received by the remote control receiving unit 105 via the signal line L109 and analyzing the remote control code of the input remote control signal.

  The registration screen display determination unit 111 is a processing unit that determines whether or not to display the registration screen by acquiring the program end time notified from the program end detection unit 106 via the signal line L110.

  In addition, the registration screen display determination unit 111 determines whether to display or not display the registration screen by obtaining a notification that the power OFF is notified from the remote control code analysis unit 110 via the signal line L111. It is a processing part to perform.

  Further, the registration screen display determination unit 111 displays the registration screen by acquiring the visitor information of the intercom device 130 acquired by the communication unit (communication means that communicates with the intercom device 130) 113 through the signal line L113. This is a processing unit that determines whether or not.

  The visitor registration screen generation unit 112 acquires the visitor image acquired from the intercom device 130 by the communication unit 113 from the signal line L116 and generates a visitor registration screen. The visitor registration process will be described later.

  The communication unit 113 communicates with the communication unit 133 of the intercom device 130 via the signal line L125. As a communication interface, PLC (Power line Communications) using a power line as a communication line is used.

  When the visitor presses a call button (not shown) of the interphone device 130, the communication unit 113 receives a visitor notification transmitted by the interphone device 130 and receives an image taken by a camera (not shown) of the interphone device 130.

  The communication unit 113 also makes an inquiry to the interphone device 130 as to whether or not the visitor notified by the visitor notification has been registered in the visitor database 131 of the interphone device 130.

  The display mode switching unit 114 performs a process of switching the display mode of the visitor notification generated by the visitor screen generation unit 117. There are two display modes: a visitor name display mode and an image display mode.

  The display mode switching unit 114 functions as a display mode switching unit that switches the display mode of the visitor screen generated by the visitor screen generation unit 117. The combining unit 108 also functions as a combining unit that generates a visitor screen in which a video based on visitor information is superimposed on a broadcast video based on a broadcast signal according to a display mode.

  FIG. 2 shows each display mode.

  FIG. 2A shows an image display mode. The received broadcast image (broadcast video) 202 is reduced and displayed on the display unit 109, transmitted from the intercom device 130, and extracted by the video signal extraction unit 116. A visitor image (visitor video) 203 is displayed.

  FIG. 2B shows a visitor name display mode, in which the display unit 109 displays the name of the visitor and a display 205 indicating that the visitor is superimposed on the broadcast image 202 in a text format. By superimposing the display 205 in the text format on the received broadcast image 202, it is possible to confirm the visitor while reducing the obstruction of viewing due to the reduction in the size of the received video being viewed.

  2C is an example of the display 206 when the corresponding person is not registered in the visitor database 131 in the visitor name display mode as in FIG. 2B.

  The text generation unit 115 generates text data as indicated by the display 205 displayed in the visitor name display mode from the visitor information acquired from the communication unit 113. As a result of the communication unit 113 inquiring the interphone device 130, if the visitor information is already registered in the visitor database 131, the registered name is used to display “ It ’s a visitor. ” Thereby, a visitor can be confirmed without confirming the visitor image 203 of a visitor.

  If the visitor information is not registered in the visitor database 131, as shown by the display 206 in FIG. 2C, text data indicating that there is a visitor such as “is a visitor” is created.

  The video signal extraction unit 116 extracts a video signal of a visitor photographed by a camera unit 402 (to be described later) of the interphone device 130 transmitted by the interphone device 130 through the signal line L125, and the visitor is transmitted via the signal line L120. It transmits to the screen generation unit 117.

  The visitor screen generation unit 117 makes an inquiry about the current display mode to the display mode storage unit 118. Then, when the display mode is the visitor name display mode, the visitor screen generation unit 117 uses the text data acquired from the text generation unit 115 via the signal line L118 and shows the display 205 in FIG. A screen on which such text data is superimposed is generated.

  In addition, the visitor screen generation unit 117 makes an inquiry about the current display mode to the display mode storage unit 118. When the display mode is the image display mode, the visitor screen generation unit 117 generates a visitor screen using the visitor image 203 acquired from the video signal extraction unit 116 via the signal line L120.

  The display mode storage unit 118 acquires the display mode switched by the display mode switching unit 114 via the signal line L126, and stores the display mode. The display mode storage unit 118 notifies the communication unit 113 and the visitor screen generation unit 117 of the current display mode via the signal line L121 and the signal line L123, respectively.

  The scaler 119 acquires the video signal decoded by the decoder 104 from the signal line L105, and expands / reduces the display size of the display unit 109. However, when the mode stored in the display mode storage unit 118 displays the visitor screen in the image display mode, the broadcast image 202 in FIG. 2A is reduced and displayed.

  The intercom device 130 includes a visitor database 131 for storing and managing visitor names and images, and a visitor image primary storage unit 132 for temporarily storing visitor images. In addition, the intercom device 130 includes a communication unit 133 that is an interface for communicating with an external device, and an image recognition unit 134 for recognizing and specifying a visitor.

  FIG. 3 is a flowchart showing a procedure of a visitor screen display process executed by the receiving apparatus of FIG. Part of the processing is performed on the intercom device 130 side in response to an inquiry on the receiving device 101 side.

  When visitor A presses call button 403 of intercom terminal 401 shown in FIG. 4, a “visitor notification” for notifying communication unit 113 that intercom device 130 has pushed the interphone is sent from intercom device 130 via signal line L125. Send. At the same time, when the call button 403 is pressed, the intercom terminal 401 starts shooting a visitor with the camera unit 402.

  The intercom device 130 transmits an image captured by the camera unit 402 to the communication unit 113 via the signal line L125. When the communication unit 113 of the receiving apparatus 101 receives the visitor notification (step S301), the communication unit 113 inquires of the display mode storage unit 118 whether the current display mode is “customer name display mode” or “image display mode” (step S302). ).

  When the display mode is the visitor name display mode (YES in step S303), the communication unit 113 inquires of the interphone device 130 about the person name of the visitor A via the signal line L125 (step S304).

  When the person is registered in the visitor database 131 in the intercom device 130 (YES in step S305), the intercom device 130 transmits the person name to the receiving device 101 via the communication line L125. A method for registering a visitor in the visitor database will be described later.

  At this time, the receiving device 101 receives the visitor name sent from the intercom device 130 by the communication unit 113 (step S306). The text generation unit 115 acquires the visitor name acquired by the communication unit 113 via the signal line L117 and generates text data “Mr. XX is a visitor” for display on the display unit 109 (step S307). ).

  When the receiving apparatus 101 inquires of the interphone apparatus 130 about the person name of the customer A and the corresponding person is not registered in the visitor database 131 in the interphone apparatus 130 (NO in step S305), the text generation unit 115 Text data “I am a visitor” to be displayed on the display unit 109 is generated (step S308).

  When the text data is generated, the visitor screen generation unit 117 generates a visitor screen for displaying the text data on the display unit 109. When the visitor screen generation unit 117 generates a visitor screen, the combining unit 108 combines the generated visitor screen with the broadcast image 202 acquired via the signal line L124 and outputs it to the display unit 109 (step S309).

  When the visitor screen is displayed, the receiving apparatus 101 waits for input of a remote control key from a remote controller (not shown) (step S310). When there is a key input from the remote controller and the key is a “return” key (“return” in step S311), the text data of the displays 205 and 206 displayed on the display unit 109 is deleted (step S312). ) And exit the visitor screen.

  In addition, the interphone device 130 receives a visitor notification from the receiving device 101 and confirms the current display mode by the display mode stored in the display mode storage unit 118. As a result, the “image display” is displayed instead of the “visitor name display mode”. In the case of “mode”, the following processing is performed.

  That is, if NO in step S303, the visitor image 203 of FIG. 2A is displayed on the television screen.

  Further, in the case of “visitor name display mode”, when the “decision” key is input while waiting for key input (“decision” in step S311), as shown by the customer image 203 in FIG. The video of the visitor is displayed on the television screen (display unit 109).

  For this purpose, the video signal extraction unit 116 extracts the customer image 203 from the video imaged by the camera unit 402 of the intercom terminal 401, which is input from the interphone device 130 via the signal line L125 (step S313).

  Further, the video of the broadcast signal input from the tuner 102 needs to be reduced and displayed as shown by the broadcast image 202 in FIG. In normal times, as shown in FIG. 5A, the high-definition video of the broadcast signal is displayed at a size of 1920 dots in the horizontal direction and 1080 lines in the vertical direction as the display size of the display unit 109. , Do not perform enlargement / reduction processing.

  However, when the visitor image 203 is displayed on the display unit 109, as shown in FIG. 5B, the scaler 119 has a broadcast signal video (broadcast image 202) with a size of 1280 dots in the horizontal direction and 720 lines in the vertical direction. Is reduced (step S314).

  In the visitor screen generation unit 117, a video image of the customer taken by the camera unit 402 and transmitted from the intercom device 130 extracted by the video signal extraction unit 116 is created. Specifically, the visitor screen generation unit 117 creates data to be displayed in the horizontal size 360 and the vertical size 240 as shown by the visitor image 203 in FIG.

  The combining unit 108 combines the broadcast image 202 having the horizontal size 1280 and the vertical size 720 input from the signal line L124 and the customer image 203 having the horizontal size 360 and the vertical size 240 input from the signal line L115. Thereafter, a video (image) obtained by synthesizing the broadcast image 202 and the visitor image 203 shown in FIG. 2A is output to the display unit 109 (step S315).

  In this embodiment, the size for outputting the broadcast image 202 to the display unit 109 is the horizontal size 1280 and the vertical size 720, and the size for outputting the visitor image 203 to the display unit 109 is the horizontal size 360 and the vertical size 240. The size is not limited to this. Alternatively, the visitor image 203 may be displayed superimposed on the broadcast image.

  When an input of a “return” button is received by the remote control receiving unit 105 while a video (image) obtained by synthesizing the broadcast image 202 and the visitor image 203 shown in FIG. 2A is being output to the display unit 109 (YES in S316). The visitor screen generation unit 117 stops generating the visitor image 203. The synthesizing unit 108 outputs only the broadcast wave video signal (broadcast image 202) input from the signal line L 124 to the display unit 109.

  The scaler 119 returns the broadcast wave video signal to the original size by setting the setting for reducing the video output input from the signal line L105 to a state in which the reduction is canceled (step S318).

  As described above, when the image display mode of the visitor notification is the visitor name display mode, the interphone device 130 connected by the PLC or the like is inquired of the visitor data, and the visitor name is acquired. The name is displayed superimposed on the video of the program being viewed. Thereby, it becomes possible to check a visitor, reducing the disturbance of video viewing.

  Next, processing for registering a visitor in the visitor database 131 in the receiving apparatus 101 will be described.

  FIG. 6 is a flowchart showing the procedure of a visitor registration process for registering a visitor executed by the receiving system of FIG. 1 in the visitor database.

  Before the flowchart of FIG. 6 is described, the operation of the intercom device 130 will be described.

  When the visitor presses the call button 403 of the intercom terminal 401, the visitor is photographed by the camera unit 402 of the intercom terminal 401, and the visitor image is stored in the visitor image primary storage unit 132 of the interphone device 130.

  Further, in the customer image primary storage unit 132, whether the images 721 to 724 of the unregistered customers in the visitor database 131 are IDs 701 to 704 for uniquely identifying the data and whether or not the registration has been confirmed. Stored with information (states 731 to 734). The states 731 to 734 in which the registration has been confirmed and the registration has not been performed are determined by a notification from the receiving apparatus 101.

  In FIG. 6, the receiving apparatus 101 starts registration processing at the end of a program and when a power OFF button on a remote controller (not shown) is input (step S601). The program end time in the program end detection unit 106 is determined from the value obtained by adding the program duration to the broadcast start time acquired from the program information.

  When the program end detection unit 106 detects the end of the program that the user is currently viewing (YES in step S602), the process proceeds to step S620. In step S620, the receiving apparatus 101 makes an inquiry about whether or not there is an unregistered customer to the intercom apparatus 130 via the signal line L125 from the communication unit 113.

  The intercom device 130 transmits the number of unregistered customers, IDs 701 to 704, images 721 to 724 and states 731 to 734 corresponding to the respective IDs 701 to 704 to the receiving device 101. The IDs 701 to 704 are identifiers for uniquely identifying the customers stored in the customer image primary storage unit 132 as described above.

  Images 721 to 724 are captured images captured by the camera unit 402 when a visitor presses the call button 403 of the intercom terminal 401.

  In the present embodiment, the number of images is one, but a sub-number may be held for one visitor or may be held as a moving image. Further, as described above, the states 731 to 734 are information indicating whether or not “registration confirmed” / “registration confirmation not performed” in the receiving apparatus 101, and the visitor image primary storage unit 132 at the visit to the customer. Is stored as “registration not yet confirmed”.

  At this time, if IDs 701 to 704 are stored in the customer image primary storage unit 132 of the interphone device 130 as shown in FIG. 7, the number of people is 4, and the IDs are 001, 002. , 003, 004.

  At this time, the image of the visitor with ID 701 (001) is the image 721, and the state is “registration confirmed” 731. Further, the image of the visitor with ID 702 (002) is the image 722, and the status is “registration confirmation not performed” 732.

  The image of the visitor with ID 703 (003) is the image 723, and the status is “registration confirmation not performed” 733. The image of the visitor with ID 704 (004) is the image 724, and the status is “registration confirmation not performed” 734. IDs 701 to 704 are IDs for uniquely specifying the visitor data, and any numerical values may be set as long as they can be specified uniquely.

  When there is an unregistered person as a result of the inquiry to the intercom device 130 (YES in step S621) and there is a registration unconfirmed customer (YES in step S622), the registration screen display determination unit 111 displays the registration screen. Is determined to be displayed.

  If it is determined that the registration screen is to be displayed, the visitor registration screen generation unit 112 generates a visitor registration screen, and the composition unit 108 outputs the visitor registration screen to the display unit 109 (step S623).

  When the unregistered person is the ID 701 to 704 in FIG. 7, the registration confirmation screen of the ID 702 whose status is not confirmed is displayed.

  FIG. 8 shows an example of a customer registration screen generated by the customer registration screen generation unit 112. A visitor image 203 for confirmation of registration is displayed on the visitor registration screen 801 of the display unit 109. In this case, an image 722 with an ID 702 of 002 is displayed.

  A registration button 803 is a button that is selected when a person to be displayed in the visitor image 203 is stored in the visitor database 131. A button 804 that is not registered is a button that is selected when a person to be displayed in the visitor image 203 is not stored in the visitor database 131. A registration button 805 is a button that is selected when a person to be displayed on the customer image 203 is registered later.

  If the user selects the button 803 to be registered while the visitor registration screen 801 is displayed (YES in step S624), the visitor registration screen generation unit 112 generates the visitor name input screen 901 shown in FIG. Prompt for name.

  A visitor image 203 registered in the visitor database 131 is displayed on the visitor name input screen 901 of the display unit 109. An area 903 displays the input name. Further, the name is input by selecting the alphabet of the key 904 with the remote controller. The name input is completed by selecting a completion button 905.

  Thus, the user inputs the visitor name on the visitor name input screen 901 (step S625). The entered visitor name is stored in the visitor name primary storage unit 120.

  When the user completes the visitor name input and ends the visitor name registration screen 901, the receiving apparatus 101 transmits a visitor database registration request to the interphone apparatus 130 via the signal line L125 by the communication unit 113. At the same time, the receiving apparatus 101 transmits the person name input by the registered customer ID and the customer name input screen 901 and stored in the customer name primary storage unit 120 (step S626).

  For example, when the receiving apparatus 101 transmits a registration request for a visitor with ID 702 (002) in FIG. 7 to the intercom apparatus 130, the data with ID 702 (002) is registered in the visitor database 131 together with the input name.

  After the registration is completed, the data stored in the visitor image primary storage unit 132 is, as shown in FIG. 10, three data: a visitor with ID 701 (001), a visitor with ID 703 (003), and a visitor with ID 704 (004). It becomes.

  When the registration request for the data of ID 702 (002) is completed, there are unregistered customers as indicated by IDs 701, 703, and 704 (YES in step S621), and there are unregistered customers as indicated by ID 703 and 704 (steps) If YES in S622, the following processing is executed. That is, in that case, the visitor registration screen generation unit 112 displays the visitor registration screen 801 again (step S623).

  However, the customer image 203 to be displayed is the image 723 of the customer with ID 703 (003). At this time, when the user selects a button 804 that is not registered on the customer registration screen 801 (NO in step S624 and NO in S627), the receiving apparatus 101 performs the following processing.

  That is, the receiving apparatus 101 transmits a request to delete the data of ID 703 (003) stored in the customer image primary storage unit 132 to the intercom apparatus 130 via the signal line L125 by the communication unit 113 (step S629). ).

  The intercom device 130 that has received the deletion request deletes the visitor data with ID 703 (003) from the visitor image primary storage unit 132. At this time, the customer data stored in the customer image primary storage unit 132 is two pieces of ID 701 (001) and ID 704 (004) as shown in FIG.

  As shown in FIG. 11, if there is an unregistered customer with ID 701 (001) and ID 704 (004) (YES in step S621), and there is an unregistered customer with ID 704 (004) (YES in step S622), customer registration is performed. The screen generation unit 112 performs the following processing. That is, the visitor registration screen generation unit 112 displays the visitor registration screen 801 again (step S623). However, the visitor image 203 displays a visitor image 724 with ID 704 (004).

  At this time, if the user later selects the registration button 805 on the customer registration screen 801 (NO in S624 and YES in S627), the receiving apparatus 101 uses the communication unit 113 via the signal line L125 to interphone. A change request is transmitted to the device 130. That is, a request for changing the status of the ID 704 (004) stored in the customer image primary storage unit 132 from “registration confirmation not performed” 734 to “registration confirmed” 731 is transmitted.

  Upon receiving the change request, the intercom apparatus 130 changes the state of the visitor data with ID 704 (004) in FIG. 11 “registration confirmation not performed” 734 to the state of visitor data with ID 704 (004) in FIG. (Step S628).

  As shown in FIG. 12, the data state change request for ID 704 (004) is completed, and there are unregistered customers as indicated by ID 701 (001) and ID 704 (004) (YES in step S621). If not (NO in step S622), the following processing is performed.

  That is, the receiving apparatus 101 again shifts to a state of waiting for the program end detection from the program end detection unit 106 and the power-off detection by the remote control code analysis unit 110 (step S601).

  Further, the interphone device 130 is inquired whether there is an unregistered customer in the visitor image primary storage unit 132, and if there is no unregistered customer as a result of the inquiry (NO in step S621), the same processing is performed. That is, the receiving apparatus 101 shifts to a state of waiting for the program end detection from the program end detection unit 106 and the power-off detection by the remote control code analysis unit 110 (step S601).

  For the processing flow for registering a visitor to the visitor database 131 when the end of the program is detected (YES in step S602), the visitor data of IDs 701 to 704 in FIG. Explained the case.

  FIG. 13 shows the state before and after the registration process. FIG. 13A shows a state before registration processing, and data 1301 indicates data of IDs 701 (001) to 704 (004) stored in the customer image primary storage unit 132. FIG. FIGS. 13B, 13 </ b> C, and 13 </ b> D show states after registration processing, and data 1302 is obtained by adding data of ID 702 (002) to the customer database 131. Data 1303 indicates data stored in the customer image primary storage unit 132, and the state of the ID 704 (004) is changed from “registration confirmation not performed” to “registration confirmed”. Data 1304 indicates ID 703 (003) which is deleted data.

  As shown by data 1303 in FIG. 13, when there is unregistered data such as ID 701 (001) and ID 704 (004) in the visitor image primary storage unit 132, but there is no unconfirmed data (step S622). NO) is as follows.

  That is, even when the end of the program is detected (YES in step S602), the visitor registration screen is not displayed on the display unit 109 every time the end of the program is detected, and the user is not required to perform more operations than necessary. .

  On the other hand, when remote control code analyzer 110 detects that the power OFF button has been pressed (NO in step S602, YES in S603), receiving apparatus 101 performs the following processing. That is, the receiving apparatus 101 makes an inquiry about whether there is unregistered customer data to the intercom apparatus 132 via the signal line L125 by the communication unit 113 (step S604).

  The intercom device 130 transmits the number of unregistered customers, IDs, images corresponding to the respective IDs, and states to the receiving device 130. As a result of the inquiry, it is assumed that three data of ID 701 (001), ID 704 (004), and ID 706 (006) in FIG. 14 are stored in the customer image primary storage unit 132.

  Here, when there is unregistered data (NO in step S605), the customer registration screen 801 of FIG. 8 is displayed regardless of the data status “registration confirmed” / “registration confirmation not yet implemented” (step S606). .

  By displaying the customer registration screen 801 without depending on the data state, the registration button 805 is selected after FIG. 8 in the registration process at the end of the program, and the data that has been “confirmed” is displayed. The registration process is also executed.

  That is, as shown in FIG. 14, when there is unregistered data ID 701 (001), ID 704 (004), and ID 706 (006) (NO in step S605), the display of the customer registration screen 801 is displayed in order from the data of ID 701 (001). This is performed (step S606).

  When the button 803 to be registered in FIG. 8 is selected (YES in step S607), the receiving apparatus 101 displays a visitor name input screen 901 on the display unit 109. The user inputs a visitor name through the input interface of the visitor name input screen 901 (step S608). The entered visitor name is stored in the visitor name primary storage unit 120.

  When the user completes the visitor name input and exits the visitor registration screen 801, the receiving apparatus 101 uses the communication unit 113 via the signal line L125 to register the visitor database registration request and the visitor ID to be registered in the interphone apparatus 130. Send. At the same time, the receiving apparatus 101 transmits the person name input to the intercom apparatus 130 via the visitor name input screen 901 and stored in the visitor name primary storage unit 120 (step S609).

  On the other hand, when the user selects the button 804 not to be registered on the visitor registration screen 801 (NO in step S607 and NO in S610), the receiving apparatus 101 deletes the data via the signal line L125 by the communication unit 113. A request is transmitted (step S612). The intercom device 130 that has received the deletion request deletes the corresponding visitor data from the visitor image primary storage unit 132.

  On the other hand, when the user later selects the registration button 805 on the visitor registration screen 801 (NO in step S607 and YES in S610), the receiving apparatus 101 executes the following processing.

  That is, if the state of the customer data stored in the intercom device 130 and the customer image primary storage unit 132 via the signal line L125 by the communication unit 113 is “registration confirmation not performed”, the receiving device 101 Send a change request to “Registration Confirmation Completed”.

  The intercom device 130 that has received the change request changes the state of the corresponding visitor data from “registration confirmation not yet performed” to “registration confirmation completed” (step S611). If the state of the visitor data stored in the visitor image primary storage unit 132 is already “registration confirmed”, the receiving apparatus 101 does not transmit a change request to the intercom apparatus 130.

  In this way, the visitor data (customer image 203) stored in the visitor image primary storage unit 132 that has been “confirmed of registration” is stored again in the visitor registration screen 801 when the power OFF button is input next time. And inquire the user about customer registration.

  When the registration confirmation of the unregistered data stored in all the customer image primary storage units 132 is completed (YES in step S605), the receiving apparatus 101 performs a power-off process (step S613).

  In the present embodiment, when a power OFF button is input, a visitor registration screen 801 is displayed and confirmation of visitor registration is performed. However, in order to ignore the visitor registration process and turn off the power of the receiving apparatus 101, the visitor registration process may be terminated by inputting the power OFF button again while the visitor registration screen 801 is displayed.

  The visitor name is stored in the visitor name primary storage unit 120 of the receiving apparatus 101 together with the visitor ID, and the interphone apparatus 130 registers the visitor ID and image in the visitor database. May be. Then, in the visitor name display mode, the intercom apparatus 130 may be inquired of the visitor ID, and only the visitor ID may be acquired to display the visitor name text.

  In this embodiment, the visitor registration process is started by detecting the program end time. However, after the program end time is detected, the visitor registration process is started a certain time before the program end time. Also good.

  Moreover, although this fixed time is the value which the receiving apparatus 101 has internally as an initial value, the user can also set it freely. In this embodiment, the program end time is determined from the value obtained by adding the program duration to the broadcast start time acquired from the program information. At this time, the next program may start. Because.

  In the present embodiment, the visitor registration process is started by detecting the program end time. However, the visitor registration process is started by detecting the CM by detecting the change in the aspect ratio of the broadcast signal from 16: 9 to 4: 3 and the change in the resolution from 1920 × 1080 to 720 × 480, etc. May be. However, at this time, the CM broadcast is displayed in a reduced size and superimposed on the visitor registration screen so that the visitor registration can be performed without disturbing the intention of the broadcaster.

  As described above, in the present embodiment, when the visitor notification image display mode of the receiving apparatus 101 is the visitor name display mode, the visitor name is obtained by inquiring the visitor name to the intercom apparatus 130. To do. And, by displaying the visitor name in a text format at a place where it is difficult to hinder program viewing, such as the lower part of the display unit 109, the area that obstructs TV viewing is reduced, and the interference with TV viewing is reduced. Visitors can be confirmed.

  In addition, if the visitor name cannot be acquired as a result of the inquiry to the intercom device 130, the user is prompted to register at the timing of detecting the end of the program or the power OFF button, thereby reducing the obstacle to viewing. However, it is possible to prevent omission of visitor registration.
