The storage device 42 is configured of, for example, one or more types of storage circuits such as a ROM (Read Only Memory), an EPROM (Erasable Programmable ROM), an EEPROM (Electrically Erasable Programmable ROM), and a RAM (Random Access Memory).

  The operation accepting unit 43 accepts an operation by the user. As illustrated in FIG. 3, the operation receiving unit 43 according to the first embodiment includes a plurality of operators 47 (47 a, 47 b, 47 c, 47 d, 47 e) corresponding to different operations. The user selectively operates the operation element 47 corresponding to the desired operation among the plurality of operation elements 47 of the operation reception unit 43. For example, the plurality of operators 47 include an operator (numeric key) 47a for specifying the number of the broadcasting station, an operator 47b for instructing increase or decrease of the number of the broadcasting station, and increase or decrease of the reproduction volume of the display device 20. , An operator 47d for instructing power on or off of the display device 20, and an operator 47e for selecting terrestrial broadcasting (terrestrial digital broadcasting) or satellite broadcasting (BS) And.

  The first transmitter 44 (exemplary first transmission unit) in FIG. 2 is a communication device that transmits a first operation signal Q1 representing an operation received by the operation reception unit 43. Specifically, the first transmitter 44 transmits the first operation signal Q1 in a first communication scheme that can be received by the display device 20. The first communication method is, for example, wireless communication using infrared light as a transmission medium. Therefore, the first transmitter 44 is configured to include, for example, a light emitting element that emits infrared light. The processing device 30 can not receive the first operation signal Q1 transmitted by the operating device 40 according to the first communication method.

  The second transmitter 45 (exemplary second transmission unit) is a communication device that transmits a second operation signal Q2 representing an operation received by the operation reception unit 43. Specifically, the second transmitter 45 transmits the second operation signal Q2 by the second communication method different from the first communication method adopted by the first transmitter 44. The second communication method is a communication method that can be received by the processing device 30, and is, for example, near field communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark).

The first communication method and the second communication method may be described in another way as communication methods in which transmission media are different.

  FIG. 4 is a flowchart illustrating the specific operation of the operation device 40. As illustrated in FIG. 4, the control device 41 stands by until the operation receiving unit 43 receives an operation by the user (Sa1: NO). When the operation reception unit 43 receives an operation by the user (Sa1: YES), the control device 41 causes the first transmitter 44 to transmit the first operation signal Q1 representing the operation according to the first communication method (Sa2), And the second operation signal Q2 representing the operation is transmitted to the second transmitter 45 in the second communication method (Sa3). That is, as exemplified in FIG. 1 or FIG. 2, the communication method (the first communication method) in which the first operation signal Q1 and the second operation signal Q2 which commonly represent the operation are different when triggered by the operation by the user And the second communication method) from the controller device 40 to the surroundings.

  When the first operation signal Q1 and the second operation signal Q2 are transmitted, the control device 41 shifts the processing to step Sa1 and waits for the user's operation. As understood from the above description, in the first embodiment, the transmission of the first operation signal Q1 by the first transmitter 44 (Sa2) and the second transmission each time the operation reception unit 43 receives an operation by the user. Transmission of the second operation signal Q2 by the device 45 (Sa3) is performed. The order of transmission of the first operation signal Q1 by the first transmitter 44 (Sa2) and transmission of the second operation signal Q2 by the second transmitter 45 (Sa3) is arbitrary. For example, the first transmitter 44 may transmit the first operation signal Q1 after transmission of the second operation signal Q2 by the second transmitter 45, or the transmission of the first operation signal Q1 by the first transmitter 44 and the first The transmission of the second operation signal Q2 by the two transmitters 45 may be performed in parallel.

  As illustrated in FIGS. 1 and 2, the display device 20 receives the first operation signal Q1 transmitted from the first transmitter 44, and operates according to the content of the operation represented by the first operation signal Q1. For example, operations such as changing the channel number of the broadcasting station (changing channels) or increasing or decreasing the reproduction volume are performed in response to the first operation signal Q1. On the other hand, the processing device 30 receives the second operation signal Q2 transmitted from the second transmitter 45. The first operation signal Q1 and the second operation signal Q2 are signals representing a common operation, and the display device 20 operates in response to the first operation signal Q1. Therefore, the second operation signal Q2 is also referred to as a signal representing the operation of the display device 20. With the above relationship as a background, the processing device 30 of the first embodiment generates history information H representing a history of reproduction by the display device 20 according to the second operation signal Q2. That is, the content of the operation on the display device 20 is transmitted by a communication method and an operation signal different from the instruction to the display device 20 for the purpose of acquiring the operation history.

  As illustrated in FIG. 2, the processing device 30 includes a control device 31, a storage device 32, a communication device 33, a receiver 34, and a timing device 35. The elements of the processing device 30 are connected to one another by one or more buses. Each element of the processing device 30 is configured of one or more devices. Some elements of the processing device 30 may be omitted.

  The control device 31 is a processor that controls the entire processing device 30, and is configured of, for example, one or more chips. The control device 31 is configured by, for example, a central processing unit (CPU) including an interface with a peripheral device, an arithmetic device, a register, and the like. Note that part or all of the functions of the control device 31 may be realized by hardware such as a DSP, an ASIC, a PLD, or an FPGA. The controller 31 executes various processes in parallel or sequentially.

  The storage device 32 is a recording medium readable by the control device 31 and stores a plurality of programs executed by the control device 31 and various data used by the control device 31. The storage device 32 is configured of, for example, one or more types of storage circuits such as a ROM, an EPROM, an EEPROM, or a RAM. The clocking device 35 (an example of a time specifying unit) is a clock circuit that generates time information indicating the current time.

  The communication device 33 communicates with another device (for example, the distribution device 12 or the management device 14) via the communication network 16. The communication device 33 is also described as, for example, a network device, a network controller, a network card, or a communication module. For example, the communication device 33 receives a video signal transmitted from the distribution device 12. As described above, the control device 31 converts the video signal received by the communication device 33 into a format that can be reproduced by the display device 20, and reproduces the content by supplying the converted video signal to the display device 20.

The control device 31 stands by until the receiver 34 receives the second operation signal Q2 (Sb1: NO). When the receiver 34 receives the second operation signal Q2 (Sb1: YES), the control device 31 specifies an operation represented by the second operation signal Q2 and generates operation information representing the operation (Sb2). The control device 31 generates history information H including operation information generated from the second operation signal Q2, time information (time stamp) generated by the time measuring device 35, and identification information of the user of the processing device 30. It stores in the memory | storage device 32 (Sb3). The identification information is registered in advance and held in the storage device 32.

  The operation information designates, for example, the number (channel number) of the broadcasting station corresponding to the content reproduced by the display device 20. For example, when the second operation signal Q2 represents an operation on the operation element 47a, operation information specifying the number of the broadcasting station corresponding to the operation element 47a is generated. In addition, when the second operation signal Q2 represents an operation on the operation element 47b, the operation information for specifying the number obtained by increasing or decreasing the number of the broadcasting station corresponding to the content displayed by the display device 20 according to the operation is It is generated.

  When the history information H is generated (Sb3), the control device 31 shifts the processing to step Sb1 and stands by to receive the second operation signal Q2. As understood from the above description, in the first embodiment, every time the operation receiving unit 43 receives an operation by the user, history information H representing the content of the operation is generated. As described above, since the display device 20 operates by the first operation signal Q1 representing an operation common to the second operation signal Q2, the history information H corresponds to information representing the history of reproduction by the display device 20. That is, the control device 31 of the first embodiment functions as an element (information generation unit) that generates history information H representing a history of reproduction by the display device 20.

  A plurality of pieces of history information H are accumulated in the storage device 32 of the processing device 30 by the operation exemplified above. The control device 31 of the processing device 30 instructs the communication device 33 to transmit a plurality of pieces of history information H stored in the storage device 32. The communication device 33 (exemplary communication unit) transmits a plurality of pieces of history information H to the management device 14 in response to an instruction from the control device 31. Note that the time when the communication device 33 transmits a plurality of pieces of history information H is arbitrary. For example, a plurality of pieces of history information H may be transmitted from the processing device 30 to the management device 14 in response to an instruction from the user, or the plurality of pieces of history information H may be transmitted from the processing device 30 to the management device 14 in a predetermined cycle. You may

  The management device 14 receives a plurality of pieces of history information H transmitted by the processing device 30 from the communication network 16 and stores the history information H for each user of the processing device 30. The management device 14 of the first embodiment provides the user with related information corresponding to the history information H of the user of the processing device 30. The related information is information corresponding to the preference of the user estimated from the history information H. For example, information representing the contents corresponding to the preference of the user or information on various products is a preferred example of the related information. Although a typical example of the transmission destination of the related information is the processing device 30, the management device 14 may transmit the related information to a terminal device such as a mobile phone or a smartphone registered in advance. The user confirms the related information using the processing device 30 or the terminal device.

  As described above, in the first embodiment, the first operation signal Q1 representing the operation accepted by the operation accepting unit 43 is transmitted by the first communication method, and the history information H representing the history of reproduction by the display device 20 is processed. A second operation signal Q2 for the device 30 to generate is transmitted in a second communication scheme. Therefore, compared with, for example, the technique of Patent Document 1, it is possible to realize the operation of the display device 20 and the generation of the history information H by the processing device 30 with a simple configuration. Further, since the history information H generated by the processing device 30 is transmitted to the management device 14, it is possible to provide the user with related information corresponding to the history information H.

  As illustrated in FIG. 3, the plurality of operators 47 (47 a, 47 b, 47 c, 47 d, 47 e) of the operation reception unit 43 correspond to the first operation unit Z1 and the second operation unit Z2 corresponding to different operations. It is divided. The first operation unit Z1 instructs, for example, an operating element 47a for specifying a broadcasting station number, an operating element 47b for instructing increase or decrease of a broadcasting station number, and power on / off of the display device 20. And an operator 47e for selecting a broadcast wave (terrestrial wave / satellite wave). The second operation unit Z2 includes an operation element 47c for instructing increase or decrease of the reproduction volume of the display device 20.

Be done. On the other hand, the operators 47 that instruct the operation of the display device 20 that does not need to be reflected in the history information H (that is, the operation that does not directly affect the viewing content) are classified in the second operation unit Z2.

  The control device 41 causes the first transmitter 44 to transmit the first operation signal Q1 representing the operation even when any of the first operation unit Z1 and the second operation unit Z2 is operated (Sa2). Further, when the first operation unit Z1 of the operation reception unit 43 is operated, the control device 41 causes the second transmitter 45 to transmit the second operation signal Q2 representing the operation (Sa3). When the operation unit Z2 is operated, the transmission of the second operation signal Q2 by the second transmitter 45 is omitted. That is, when the second operation unit Z2 is operated, the first transmitter 44 transmits the first operation signal Q1 to the display device 20, but the second transmitter 45 transmits the second operation signal Q2 to the processing device 30. do not do. The operation of the display device 20 that has received the first operation signal Q1 and the operation of the processing device 30 that has received the second operation signal Q2 are the same as in the first embodiment.

  Also in the second embodiment, the same effect as that of the first embodiment is realized. In the second embodiment, when the second operation unit Z2 is operated, the first operation signal Q1 representing the operation is transmitted to the display device 20, but the transmission of the second operation signal Q2 is omitted. Therefore, there is an advantage that the number of transmissions of the second operation signal Q2 by the second transmitter 45 is reduced.
