  The input unit 21e is an interface for receiving various signals. The input unit 21e receives a voice detection signal from the sensor 24. The input unit 21e converts the received voice detection signal into data and converts it into a digital voice detection signal. Thereafter, the input unit 21e sends the converted voice detection signal to the processing unit 21g.

  The image composition unit 21f receives an HDMI (registered trademark) signal from the external device 101 via the reception unit 21a. At the same time, when receiving the provision information from the information provision apparatus 11 of the information provision system 1 via the communication unit 21c and further receiving the composite image display instruction from the processing unit 21g, the image composition unit 21f is included in the HDMI (registered trademark) signal. Image synthesis processing for mixing the image signal to be provided and the provided information. The image composition unit 21f temporarily stores the received provision information.

  Specifically, when receiving the HDMI (registered trademark) signal from the receiving unit 21 a, the image composition unit 21 f decodes the HDMI (registered trademark) signal to generate an audio signal and an image signal. Thereafter, the image composition unit 21f mixes the generated image signal with the provision information received from the communication unit 21c. For example, as shown in FIG. 5, when the normal image A1 is displayed on the screen 22A of the receiver 22, the image composition unit 21f reduces the normal image A1 by a predetermined ratio as shown in FIG. A11 is generated. Thereby, the image composition unit 21f generates an L-shaped blank portion B11 for the screen 22A. Thereafter, the image composition unit 21f generates a composite image for displaying both of the L-shaped blank portion B11 by mixing the provision information C1 as shown in FIG. That is, the image composition unit 21f generates an image signal for displaying a reduced image of a television program and displaying provided information using an L-shaped image by image composition processing.

  Next, the image composition unit 21f generates an HDMI (registered trademark) signal by encoding the image signal generated by the image composition processing and the previously generated audio signal, and transmits the HDMI (registered trademark) signal to the transmission unit 21b. Send to. The image composition unit 21f performs generation of an image signal and generation of an HDMI (registered trademark) signal based on the image composition processing until the provision information ends. Thereafter, the image composition unit 21f notifies the processing unit 21g that transmission of the HDMI (registered trademark) signal for the composite image has been completed.

  Thereafter, upon receiving a re-display instruction from the processing unit 21g, the image composition unit 21f uses the provision information stored temporarily to again display an image composition for displaying a composite image using an L-shaped image. Process. Thereby, the image composition unit 21f again generates an HDMI (registered trademark) signal for displaying the provided information as an L-shaped image, and sends the HDMI (registered trademark) signal to the transmission unit 21b.

  The storage unit 21h of the image mixing device 21 is a storage device that stores various data.

  The processing unit 21g performs various processes related to the image mixing device 21. When the processing unit 21g receives the position information from the GPS receiving unit 21d, the processing unit 21g obtains the position of the GPS receiving unit 21d, that is, the location of the device installation location, from the longitude and latitude indicated by the position information. In this case, the processing unit 21g checks the location of the device installation location corresponding to the longitude and latitude from the Internet, for example, the municipality code in this embodiment, via the communication unit 21c and the communication network NW. The processing unit 21g stores the municipal code checked by the GPS receiving unit 21d in the storage unit 21h. Thereafter, the processing unit 21g periodically checks the municipality code using the GPS receiving unit 21d, and updates the municipality code stored in the storage unit 21h if the code is changed.

  When the processing unit 21g receives an instruction to specify the type of information from the user's personal computer via the communication unit 21c, the processing unit 21g reads a reception list illustrated in FIG. 8 stored in the storage unit 21h in advance. Then, the processing unit 21g updates the reception list according to the type of information input from the personal computer. The processing unit 21g is a threshold value received from the personal computer of the user via the communication unit 21c. Upon receiving the threshold value for selecting information, the processing unit 21g reads the reception list stored in the storage unit 21h. Then, the processing unit 21g updates the reception list with the threshold value received from the personal computer. That is, the reception list can be changed by the personal computer.

  When the receiving unit 21a receives an HDMI (registered trademark) signal from the external device 101, the processing unit 21g receives a receiving unit when the communication unit 21c does not receive the provision information from the information providing apparatus 11 via the communication network NW. 21a is controlled, and the HDMI (registered trademark) signal received by the receiving unit 21a is sent to the transmitting unit 21b as it is.

  In this state, when receiving the information reception notification from the communication unit 21c, the processing unit 21g checks the characteristics of the provided information received by the communication unit 21c from the communication network NW using the additional information added to this information. Thereafter, the processing unit 21g collates the municipality code stored in the storage unit 21h with the municipality code of the additional information. When the two codes match by the collation, the processing unit 21g collates the type of information in the reception list stored in the storage unit 21h with the type of information in the additional information. When the two types match by the collation, the processing unit 21g compares the threshold value of the reception list with the numerical value included in the provided information, for example, the seismic intensity of the earthquake and the height of the tsunami. When the numerical value included in the provided information is larger than the threshold value, the processing unit 21g controls the reception unit 21a to send an HDMI (registered trademark) signal to the image composition unit 21f. At the same time, the processing unit 21g controls the communication unit 21c to send the received provision information to the image synthesis unit 21f, and sends an instruction to display a composite image to the image synthesis unit 21f.

  Thereafter, when the processing unit 21g receives a notification of completion of transmission of the HDMI (registered trademark) signal for the composite image from the image combining unit 21f, the processing unit 21g transmits the received HDMI (registered trademark) signal to the receiving unit 21a. It controls to output to 21b.

  When the processing unit 21g receives a voice detection signal from the sensor 24 after sending a synthetic image display instruction to the image synthesis unit 21f, the processing unit 21g checks the level of the voice represented by the voice detection signal and the duration of the voice. When the audio level is higher than the predetermined level and the audio duration is shorter than the set time, that is, the viewer is surprised, for example, “A”, “What”, “What”, “ When a voice such as “Ah” is given, the processing unit 21g sends a re-display instruction for displaying the provided information again to the image composition unit 21f.

  The above is the configuration of the information provision display system. Next, the operation of the information provision display system will be described. On the information providing system 1 side for managing and providing information, the information providing apparatus 11 collects various types of information from the source list. Thereafter, the information providing apparatus 11 transmits the collected information as provided information to a user who uses the information providing service, that is, a user registered in the destination list. At this time, the information providing apparatus 11 adds the transmission source, the type of information, and the municipal code to the provided information as characteristics of the provided information and transmits the information.

  The information display system 2 installed on the user side who uses the information providing service converts the digital transmission signal of a television program or the like from the existing system 100 into an HDMI (registered trademark) signal by the external device 101, and an image mixing device 21 and the receiver 23. If the provision information is not received from the information provision system 1 via the communication network NW, the image mixing device 21 sends an HDMI (registered trademark) signal to the receiver 22 as it is. Thereby, the receiver 22 displays a television program or the like by an HDMI (registered trademark) signal. Further, since the receiver 23 directly receives an HDMI (registered trademark) signal from the external device 101, a normal screen such as a television program is displayed.

  When the image mixing device 21 receives provision information from the information providing system 1 while the receiver 22 or the receiver 23 is displaying a television program or the like, the image mixing device 21 decodes the HDMI (registered trademark) signal. Thus, an image signal and an audio signal are generated. Thereafter, the image mixing device 21 performs an image composition process, and generates an image signal for displaying provided information using an L-shaped image and displaying a television program using a reduced screen. Then, the image mixing device 21 encodes the image signal and the audio signal generated by the image synthesis process, and converts them into an HDMI (registered trademark) signal. The image mixing device 21 sends the HDMI (registered trademark) signal thus generated to the receiver 22.

  When the receiver 22 receives the HDMI (registered trademark) signal from the image mixing device 21, the receiver 22 displays the provided information as an L-shaped image and the television program as a reduced screen by the HDMI (registered trademark) signal. . Then, when the display of the provided information is finished, the receiver 22 displays a normal screen.

  By the way, when the viewer watching the provided information displayed on the receiver 22 makes a surprise voice or the like, the image mixing device 21 detects the surprise voice by the sound detection signal from the sensor 24. Thereafter, the image mixing device 21 again generates an HDMI (registered trademark) digital transmission signal for displaying the provided information as an L-shaped image and displaying the television program as a reduced screen. Then, the image mixing device 21 sends this digital transmission signal to the receiver 22. As a result, the receiver 22 again displays the provided information using the L-shaped image and the television program using the reduced screen.

  As described above, in this embodiment, the case where the provided information is displayed using the receiver 22 that displays a home TV program or the like has been described. However, the present invention is not limited to this. For example, even when the projector connected to the personal computer displays an image on the screen, if the image mixing device 21 according to this embodiment is connected between the personal computer and the projector, for example, emergency information Is displayed on the screen as an L-shaped image. In addition, the present invention is applicable to various fields such as digital signage and movie theaters.

In this embodiment, the information display system 2 is configured as shown in FIG. 10 in the information providing display system according to the first embodiment. In this embodiment, components that are the same as or the same as those in the first embodiment described above are denoted by the same reference numerals, and description thereof is omitted.

  In this embodiment, the L-shaped image displayed on the receiver 22 can be deleted by the user or viewer. For this purpose, the information display system 2 includes a switch 25 that is detachable from the image mixing device 21. For example, the switch 25 is used by being placed near the receiver 22 connected to the image mixing device 21.

  The switch 25 is a push button type switch that is operated by a user viewing the receiver 22 or a viewer. The switch 25 outputs an operation signal to the image mixing device 21 when the button is pressed.

  The image mixing device 21 has basically the same configuration as that of the first embodiment. In the image mixing device 21 according to this embodiment, as shown in FIG. 11, a switch 25 can be connected to the input unit 21e.

  The input unit 21e receives the sound detection signal from the sensor 24 as in the first embodiment. Moreover, the input part 21e will send a connection signal to the process part 21g, if the switch 25 is connected by the user. At the same time, the input unit 21e stops receiving the voice detection signal from the sensor 24. Thereafter, when receiving the operation signal from the switch 25, the input unit 21e converts the operation signal into data, converts it into a digital operation signal, and sends the converted operation signal to the processing unit 21g.

  The image composition unit 21f of the image mixing device 21 receives an HDMI (registered trademark) signal from the external device 101 via the reception unit 21a. At the same time, when receiving the provision information from the information provision apparatus 11 of the information provision system 1 via the communication unit 21c and further receiving the composite image display instruction from the processing unit 21g, the image composition unit 21f is included in the HDMI (registered trademark) signal. Image synthesis processing for synthesizing the provided image signal and the provided information. At the same time, the image composition unit 21f temporarily stores the provision information received from the information provision apparatus 11.

  Specifically, when receiving the HDMI (registered trademark) signal from the receiving unit 21a, the image combining unit 21f displays a reduced image such as a TV program reduced at a predetermined ratio, as in the first embodiment, and Then, an image signal for displaying the provided information on the L-shaped image is generated by image synthesis processing. The image compositing unit 21f generates an image signal based on the image compositing process only for a predetermined time, for example, about 10 minutes, using the provision information stored temporarily. That is, the image compositing unit 21f repeatedly displays the provided information on the L-shaped image for about 10 minutes.

  Next, the image synthesis unit 21f encodes the image signal generated by the image synthesis process and the previously generated audio signal to generate an HDMI (registered trademark) signal, and transmits the generated HDMI (registered trademark) signal Send to part 21b. Then, when the predetermined time has elapsed, the image composition unit 21f notifies the processing unit 21g of the end of sending the composite image digital transmission signal.

  When the image composition unit 21f receives an instruction to stop image composition from the processing unit 21g while generating an image signal based on the image composition process and generating an HDMI (registered trademark) signal, The generation of the image signal based on the synthesis process and the generation of the HDMI (registered trademark) signal are stopped. Thereafter, the image composition unit 21f notifies the processing unit 21g that transmission of the HDMI (registered trademark) signal for the composite image has been completed.

  The processing unit 21g performs the following process in addition to the process of the first embodiment. That is, after receiving the connection signal from the input unit 21e, when the receiving unit 21a receives the HDMI (registered trademark) signal from the external device 101, the communication unit 21c receives the provision information from the information providing apparatus 11 via the communication network NW. When not received, the processing unit 21g sends the HDMI (registered trademark) signal received by the receiving unit 21a to the transmitting unit 21b as it is. This is the same as in the first embodiment.

  In this state, when the processing unit 21g receives the information reception notification from the communication unit 21c, the processing unit 21g checks the additional information added to the information about the provided information received by the communication unit 21c. Next, the processing unit 21g collates the municipality code stored in the storage unit 21h with the municipality code of the additional information. When the two codes match by the collation, the processing unit 21g collates the type of information in the reception list stored in the storage unit 21h with the type of information in the additional information. When the two pieces of information are matched by the collation, the processing unit 21g compares the threshold value of the reception list with the numerical value included in the provided information, for example, the seismic intensity of the earthquake or the height of the tsunami, and the numerical value included in the provided information is the threshold value. When larger, the processing unit 21g controls the receiving unit 21a to send an HDMI (registered trademark) signal to the image composition unit 21f. At the same time, the processing unit 21g controls the image composition unit 21f to send the provision information received by the communication unit 21c, and sends a composite image display instruction.

  The processing unit 21g receives an operation signal from the switch 25 after sending a composite image display instruction to the image composition unit 21f, or finishes sending an HDMI (registered trademark) signal for composite image from the image composition unit 21f. When the notification is received, control is performed so that the HDMI (registered trademark) signal output from the receiving unit 21a is output to the transmitting unit 21b. At the same time, the processing unit 21g sends an image synthesis stop instruction to the image synthesis unit 21f.

  The above is the configuration of the information provision display system. Next, the operation of the information provision display system will be described. The operation for the receiver 22 of the information display system 2 to display a normal image is the same as in the first embodiment.

  By the way, when the user connects the switch 25 to the image mixing device 21, the image mixing device 21 stops receiving the sound detection signal from the sensor 24 and enters the state of receiving the operation signal from the switch 25.

  When the receiver 22 is displaying a normal screen in such a state and the image mixing device 21 receives the provision information from the information providing system 1, the image mixing device 21 decodes the HDMI (registered trademark) signal, An image signal and an audio signal are generated. Thereafter, the image mixing device 21 performs an image composition process, and generates an image signal for displaying provided information using an L-shaped image and displaying a television program using a reduced screen. The image mixing device 21 repeatedly generates an image signal based on the image composition processing for a predetermined time using the provision information stored temporarily. Then, the image composition unit 21f encodes the image signal and the audio signal generated by the image composition processing and converts them into an HDMI (registered trademark) signal.

  The image mixing device 21 sends the HDMI (registered trademark) signal thus generated to the receiver 22 for a predetermined time. During this time, when the user or viewer operates the switch 25, in the image mixing device 21, the processing unit 21g sends an instruction to stop image synthesis to the image synthesis unit 21f. When the image composition unit 21f receives an instruction to stop image composition, the image composition unit 21f stops the image composition process. Thereafter, the image composition unit 21f notifies the processing unit 21g that transmission of the HDMI (registered trademark) signal for the composite image has been completed. As a result, an image of a normal television program is displayed on the receiver 22.

  Thus, according to this embodiment, when the user or the viewer operates the switch 25 while the provision information based on the L-shaped image is displayed on the receiver 22, the display of the provision information based on the L-shaped image is performed. Ends. In other words, since the receiver 22 continues to display the provided information as an L-shaped image until the user or viewer operates the switch 25, the provided information can be reliably transmitted to the user or viewer. To.
