FIG. 2 is a diagram showing an example of the hardware configuration of the voice recognition server 130. The voice recognition server 130 is a device that recognizes the control content for the TV receiver 170 from the voice of the operator. The voice recognition server 130 may be physically configured as a computer device including a processor 131, a memory 132, a storage 133, a communication device 134, a bus 135, and the like. In the following description, the word "device" can be read as a circuit, a device, a unit, or the like. The hardware configuration of the voice recognition server 130 may be configured to include one or more of the devices shown in the figure, or may be configured not to include some of the devices.

The processor 131 operates, for example, an operating system to control the entire computer. The processor 131 may be composed of a central processing unit (CPU: Central Processing Unit) including an interface with peripheral devices, a control device, an arithmetic unit, a register, and the like. Further, the processor 131 reads a program (program code), a software module, and data from the storage 133 and / or the communication device 134 into the memory 132, and executes various processes according to these. As the program, a program that causes a computer to execute at least a part of the operation of the voice recognition server 130 is used. Various processes executed in the voice recognition server 130 may be executed by one processor 131, or may be executed simultaneously or sequentially by two or more processors 131. The processor 131 may be mounted on one or more chips. The program may be transmitted from the network via a telecommunication line.

The memory 132 is a computer-readable recording medium, and is, for example, a ROM (Read Only Memory), an EPROM (Erasable Program ROM), an EPROM (Electrically Erasable Program ROM), a RAM (Random Access Memory), or the like. May be done. The memory 132 may be called a register, a cache, a main memory (main storage device), or the like. The memory 132 can store a program (program code), a software module, or the like that can be executed to carry out the method according to the embodiment of the present invention.

The storage 133 is a computer-readable recording medium, for example, an optical disk such as a CD-ROM (Compact Disc ROM), a hard disk drive, a flexible disk, a magneto-optical disk (for example, a compact disk, a digital versatile disk, a Blu-ray). It may consist of at least one (registered trademark) disk), smart card, flash memory (eg, card, stick, key drive), floppy (registered trademark) disk, magnetic strip, and the like. The storage 133 may be referred to as an auxiliary storage device.

The communication device 134 is hardware (transmission / reception device) for communicating between computers via at least one of a wired network and a wireless network, and is also referred to as, for example, a network device, a network controller, a network card, a communication module, or the like. The communication device 134 includes, for example, a high frequency switch, a duplexer, a filter, a frequency synthesizer, and the like in order to realize at least one of frequency division duplex (FDD) and time division duplex (TDD: Time Division Duplex). It may be composed of.

Further, each device such as the processor 131 and the memory 132 is connected by a bus 135 for communicating information. The bus 135 may be composed of a single bus, or may be composed of different buses between the devices.

Further, the voice recognition server 130 includes a microprocessor, a digital signal processor (DSP: Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), a PLC (Programmable Logic Device), an FPGA (File), and an FPGA (File). It may be configured by, and a part or all of each functional block may be realized by the hardware. For example, processor 131 may be implemented on at least one of these hardware.

Returning to FIG. 1, the management server 140 is a device that manages the user terminals 120 and STB 150 connected via the communication network 180. For example, the management server 140 instructs either the STB 150 or the infrared device 160 to transmit a control signal according to the control content recognized by the voice recognition server 130. The management server 140 physically has the same configuration as the voice recognition server 130.

The STB 150 is a control device that controls the TV receiver 170. Further, the STB 150 receives various broadcast waves and supplies video and audio (hereinafter, may be collectively referred to as “content”) corresponding to the received broadcast waves to the TV receiver 170. In addition, the STB150 may provide various services or functions related to broadcasting or video. Here, it is assumed that the broadcast received by the STB150 includes a specialized channel broadcast, a BS (Broadcasting Satellites) broadcast, and a terrestrial digital television broadcast. The STB 150 physically includes a tuner 151 in addition to the same configuration as the voice recognition server 130. The tuner 151 receives a broadcast wave for broadcasting a video having a resolution corresponding to the tuner 151 and converts it into a video signal and an audio signal. For example, when the tuner 151 supports 4K resolution, the tuner 151 receives a broadcast wave (hereinafter, referred to as "4K broadcast wave") for broadcasting a video having 4K resolution according to a standard of 4K broadcasting. This 4K resolution means a screen resolution of 3840 pixels or more horizontally and 2160 pixels or more vertically. In addition, an application program for realizing the above-mentioned agent service function is pre-installed in the STB150.

The infrared device 160 is a control device that controls the TV receiver 170 using infrared rays. However, the STB 150 and the infrared device 160 have different control functions. For example, the infrared device 160 can control the functions realized by the TV receiver 170 alone regardless of the STB 150, but can control the functions realized by the TV receiver 170 alone and not realized by the TV receiver 170 alone. Can not do it. The infrared device 160 is installed within a predetermined range from the TV receiver 170. This predetermined range is, for example, a range in which an infrared ray of a predetermined amount or more reaches. The STB 150 physically includes a transmitter 161 that emits infrared rays, in addition to the same configuration as the voice recognition server 130.

The TV receiver 170 is a home appliance that receives a broadcast wave of a specific broadcast, displays a video corresponding to the received broadcast wave, and outputs a corresponding sound. Further, when the video and audio are supplied from the STB 150, the TV receiver 170 displays the video and outputs the audio. Here, it is assumed that the specific broadcasting includes terrestrial digital television broadcasting. In this case, at least a part of the broadcast content that can be received by the TV receiver 170 and the broadcast content that can be received by the STB 150 overlap. The TV receiver 170 includes a tuner 171 and a display unit 172. In this way, both the tuner 171 and the tuner 151 are connected to the TV receiver 170. Similar to the tuner 151 described above, the tuner 171 receives a broadcast wave for broadcasting a video having a resolution corresponding to the tuner 171 and converts it into a video signal. The resolution supported by the tuner 171 may be different from the resolution supported by the tuner 151 described above. The display unit 172 displays an image corresponding to the image signal with a predetermined resolution. Here, it is assumed that the resolution of the display unit 172 is 4K resolution. In this case, the resolution of the image displayed on the display unit 172 is up to 4K resolution.

FIG. 3 is a diagram showing an example of the functional configuration of the control system 100. The voice recognition server 130 functionally includes a receiving unit 231, a voice recognition unit 232, and a transmitting unit 233. In these functions, by loading predetermined software (program) on the hardware such as the processor 131 and the memory 132, the processor 131 performs an operation, and the communication by the communication device 134 and the data in the memory 132 or the storage 133 are stored. It is realized by controlling at least one of reading and writing.

The reception unit 231 receives the voice signal when the input / output terminal 110 or the user terminal 120 acquires the voice of the operator and the voice signal corresponding to the voice is transmitted from the input / output terminal 110 or the user terminal 120. .. The operator's voice includes, for example, a control target and a control content. The control target is, for example, a TV receiver 170. The control content is, for example, a content indicating the operation of the TV receiver 170. The voice signal received by the receiving unit 231 is supplied to the voice recognition unit 232.

The voice recognition unit 232 performs voice recognition processing on the voice signal received by the reception unit 231 to recognize the content of the voice indicated by the voice signal. At this time, it is preferable to interpret the operator's intention based on the context. Examples of the voice recognition method include a method using an acoustic model called a hidden Markov model and a method using deep learning. However, the voice recognition method is not limited to these methods, and any method may be used. The result of voice recognition indicating the content recognized by the voice recognition unit 232 is supplied to the transmission unit 233.

The transmission unit 233 transmits the result of the voice recognition performed by the voice recognition unit 232 to the management server 140. This transmission may be performed via the communication network 180, or may be performed via a local network different from the communication network 180.

The management server 140 functionally includes a receiving unit 241, a determining unit 242, and an indicating unit 243. Similar to the voice recognition server 130 described above, these functions are performed by the processor by loading predetermined software (program) on hardware such as a processor and memory, and communication by a communication device or memory or memory. It is realized by controlling at least one of reading and writing of data in the storage.

When the voice recognition result of the operator is transmitted from the voice recognition server 130, the receiving unit 241 receives the voice recognition result. The voice recognition result received by the receiving unit 241 is supplied to the determination unit 242 and the indicating unit 243.

The determination unit 242 determines the control subject for the TV receiver 170 to be either the STB 150 or the infrared device 160 based on the control content according to the operation of the operator and the functions related to the control of the STB 150 and the infrared device 160. The control content is included in, for example, the result of voice recognition. The control-related functions may include, for example, controllable functions as well as the resolutions of tuner 151 and tuner 171. For example, when the control content according to the operation of the operator indicates that the TV receiver 170 displays the broadcasted image, the image is displayed using the tuner 151 of the STB150 when the STB150 controls. When the infrared device 160 controls, the image is displayed using the tuner 171 of the TV receiver 170. As described above, since the STB 150 corresponds to the tuner 151, the function of the STB 150 may include the resolution of the tuner 151 of the STB 150. Further, since the infrared device 160 corresponds to the tuner 171 of the TV receiver 170, the function of the infrared device 160 may include the resolution of the tuner 171. Information indicating the functions related to the control of the STB 150 and the infrared device 160 may be acquired from, for example, the STB 150 or from the TV receiver 170 via the STB 150 and stored in the storage of the management server 140. Alternatively, the information indicating the function related to the control of the STB 150 and the infrared device 160 may be input according to the operation of the administrator and stored in the storage of the management server 140. The control subject is determined to be, for example, the STB 150 or the infrared device 160, which has a function capable of realizing the control content according to the operation of the operator in a better form. Information for identifying the control subject determined by the determination unit 242 is supplied to the instruction unit 243.

The instruction unit 243 instructs the control subject determined by the determination unit 242 to transmit a control signal according to the control content to the TV receiver 170. Specifically, the instruction unit 243 generates a control instruction instructing the TV receiver 170 to transmit a control signal according to the control content, and transmits this control instruction to the control subject. This control instruction includes an identifier that uniquely identifies the control subject. At this time, for example, the control instruction is first transmitted to the STB150. When the control subject is the infrared device 160, the control instruction is transferred from the STB 150 to the infrared device 160. That is, when the control subject is STB150, the control instruction is directly transmitted to the control subject. On the other hand, when the control subject is the infrared device 160, the control instruction is transmitted to the control subject via the STB 150.

The STB 150 functionally includes a receiving unit 251, a subject determination unit 252, a transmitting unit 253, and a transfer unit 254. Similar to the voice recognition server 130 described above, these functions are performed by the processor by loading predetermined software (program) on hardware such as a processor and memory, and communication by a communication device or memory or memory. It is realized by controlling at least one of reading and writing of data in the storage.

When the control instruction is transmitted from the management server 140, the receiving unit 251 receives the control instruction. The control instruction received by the receiving unit 251 is supplied to the subject determination unit 252.

The subject determination unit 252 determines whether or not the STB 150 is the control subject based on the identifier included in the control instruction received by the reception unit 251. This determination is made, for example, by whether or not the control instruction includes the identifier of STB150. The determination result of the subject determination unit 252 is supplied to the transmission unit 253 or the transfer unit 254.

When the subject determination unit 252 determines that the STB 150 is the control subject, the transmission unit 253 transmits a control signal according to the control content to the TV receiver 170 according to the control instruction. This control signal is transmitted via the communication line 190.

When the subject determination unit 252 determines that the STB 150 is not the control subject, the transfer unit 254 transfers the control instruction to another control device identified by the identifier included in the control instruction, that is, the infrared device 160.

The infrared device 160 functionally has a receiving unit 261 and a transmitting unit 262. Similar to the voice recognition server 130 described above, these functions are performed by the processor by loading predetermined software (program) on hardware such as a processor and memory, and communication by a communication device or a transmitter 161. It is realized by controlling at least one of reading and writing of data in memory or storage.

When the control instruction is transferred from the STB 150, the receiving unit 261 receives the control instruction. The control instruction received by the receiving unit 251 is supplied to the transmitting unit 262.

The transmission unit 262 transmits a control signal according to the control content to the TV receiver 170 according to the control instruction received by the reception unit 261. This control signal is transmitted from the transmitter 161 using infrared rays.

2. 2. Operation FIGS. 4 and 5 are sequence charts showing an example of the operation of the control system 100. The input / output terminal 110 or the user terminal 120 is activated, for example, when the operator utters a predetermined keyword by voice. Here, when the operator activates the input / output terminal 110 and then emits a voice "Show soccer" to the input / output terminal 110 in order to instruct the TV receiver 170 to play a soccer program. Is assumed.

In step S11, the input / output terminal 110 acquires the voice of the operator and converts it into a voice signal. For example, the voice "Show me soccer" is converted into a voice signal.

In step S12, the input / output terminal 110 transmits the audio signal obtained in step S11 to STB150. The STB 150 receives this audio signal at the receiving unit 251.

In step S13, the STB 150 transmits the received voice signal from the transmission unit 253 to the voice recognition server 130. The voice recognition server 130 receives this voice signal at the receiving unit 231.

In step S14, the voice recognition server 130 recognizes the content of the voice indicated by the voice signal by the voice recognition unit 232. At this time, if the voice is in Japanese, the content of the voice is interpreted based on the context of Japanese. For example, when the voice "Show me soccer" is recognized, the control content of playing a soccer program on the TV receiver 170 is recognized.

In step S15, the voice recognition server 130 transmits the result of the voice recognition performed in step S14 from the transmission unit 233 to the management server 140. The management server 140 receives the result of this voice recognition in the receiving unit 241.

In step S16, the management server 140 determines the control subject in the determination unit 242 based on the received voice recognition result.

FIG. 6 is a diagram showing an example of a method of determining a control subject. In this example, when the resolution of the tuner 151 of the STB 150 is equal to or higher than the resolution of the tuner 171 of the TV receiver 170, the STB 150 is determined as the control subject. On the other hand, when the resolution of the tuner 151 of the STB150 is lower than the resolution of the tuner 171 of the TV receiver 170, that is, when the resolution of the tuner 171 of the TV receiver 170 is higher than the resolution of the tuner 151 of the STB150, the infrared device 160 Is determined as the control subject. The resolution of the tuner 151 and the resolution of the tuner 171 are stored in advance in the storage of the management server 140. For example, when the resolution of the tuner 151 of the STB 150 is 4K resolution and the resolution of the tuner 171 of the TV receiver 170 is also 4K resolution, the STB 150 is determined as the control subject.

In step S17, the management server 140 generates a control instruction on the instruction unit 243 based on the result of voice recognition. For example, the control instruction includes an instruction for the home appliance to be controlled and an identifier that uniquely identifies the control subject. For example, when STB150 is determined to be the control subject and the result of voice recognition includes the control content of playing a soccer program on the TV receiver 170, the control instruction states that the soccer program should be played on the TV receiver 170. The instruction and the identifier of STB150 are included.

In step S18, the management server 140 transmits the control instruction generated in step S17 from the instruction unit 243 to the STB150. The STB 150 receives this control instruction at the receiving unit 251.

In step S19, the STB 150 determines whether or not the control subject is the STB 150 by the subject determination unit 252 based on the received control instruction. For example, when the control instruction includes the identifier of STB150, it is determined that the control subject is STB150. In this case, the determination in step S19 becomes YES, and the process proceeds to step S20.

In step S20, the STB 150 transmits a control signal corresponding to the received control instruction from the transmission unit 253 to the TV receiver 170. For example, when the control instruction includes an instruction to play a soccer program on the TV receiver 170, a control signal for controlling the TV receiver 170 to play the soccer program is transmitted to the TV receiver 170. Further, in this case, the tuner 151 receives a broadcast wave indicating the video and audio of the soccer program and converts it into a video signal and an audio signal. For example, when the tuner 151 supports 4K resolution, the 4K broadcast wave of digital television broadcasting is received and converted into a video signal and an audio signal. Then, the video signal and the audio signal are transmitted to the TV receiver 170 together with the control signal. The TV receiver 170 receives the control signal, the video signal, and the audio signal.

In step S21, the TV receiver 170 operates according to the received control signal. For example, when a control signal for controlling to play a soccer program is received, the TV receiver 170 operates to play the soccer program. Specifically, the video of the soccer program corresponding to the video signal received together with the control signal is displayed on the display unit 172, and the sound of the soccer program corresponding to the audio signal is output. For example, when the tuner 151 of STB150 supports 4K resolution, the image of 4K resolution of digital television broadcasting is displayed and the sound corresponding to this image is output. At this time, the tuner 171 of the TV receiver 170 is not used.

On the other hand, in step S16 described above, for example, when the resolution of the tuner 151 of the STB 150 is 2K resolution and the resolution of the tuner 171 of the TV receiver 170 is 4K resolution, the infrared device 160 is determined as the control subject. In this case, in step S18 described above, a control instruction including the identifier of the infrared device 160 is transmitted to the STB 150. In the following step S19, since the control instruction does not include the identifier of STB150, it is determined that the control subject is not STB150. In this case, the determination in step S19 becomes NO, and the process proceeds to step S22 shown in FIG.

In step S22, the STB 150 transfers the received control instruction from the transfer unit 254 to the control subject identified from the identifier included in the control instruction. For example, when the control instruction includes the identifier of the infrared device 160, this control instruction is transferred to the infrared device 160. The infrared device 160 receives this control instruction at the receiving unit 261.

In step S23, the infrared device 160 transmits a control signal corresponding to the received control instruction from the transmission unit 262 to the TV receiver 170 using infrared rays. For example, when the control instruction includes an instruction to play a soccer program on the TV receiver 170, a control signal for controlling the TV receiver 170 to play the soccer program is transmitted to the TV receiver 170.

In step S24, the TV receiver 170 operates according to the received control signal. For example, when a control signal for controlling to play a soccer program is received, the TV receiver 170 operates to play the soccer program. Specifically, the tuner 171 receives a broadcast wave indicating the video and audio of the soccer program, converts it into a video signal and an audio signal, and displays the video of the soccer program corresponding to the video signal on the display unit 172. At the same time, the sound of the soccer program corresponding to the sound signal is output. For example, when the tuner 171 of the TV receiver 170 supports 4K resolution, the 4K broadcast wave of the digital TV broadcast is received, the 4K resolution video of the digital TV broadcast is displayed, and the audio corresponding to this video is displayed. Is output. At this time, the tuner 151 of STB150 is not used.

When the operator emits voice toward the user terminal 120, the user terminal 120 acquires the voice instead of the input / output terminal 110. In this case, the user terminal 120 converts this voice into a voice signal and transmits it to the voice recognition server 130 via the communication network 180. The subsequent processing is the same as the processing after step S14 described above.

In this embodiment, "STB150", "infrared device 160", "management server 140", "tuner 151", "tuner 171", "receiver 251", "transmitter 253", "receiver 261" , "Transmitting unit 262" are the "first control device", "second control device", "management device", "first tuner", "second tuner", and "first receiving unit" according to the present invention, respectively. , "First transmitter", "second receiver", "second transmitter". Further, in the present embodiment, the "resolution supported by the tuner 151", the "resolution supported by the tuner 171", the "broadcast wave" received by the "tuner 151", the "broadcast wave" received by the "tuner 171", and the "broadcast wave", " The "instruction" is used as the "first resolution", the "second resolution", the "first broadcast wave", the "second broadcast wave", and the "information indicating the control content" according to the present invention, respectively.

According to the embodiment described above, among the STB 150 and the infrared device 160 that control the TV receiver 170 when the operator performs an operation instructing the TV receiver 170 to display an image. Since the control device capable of displaying the image at a higher resolution is determined by the control subject, the control device suitable for the operation of the operator can control the TV receiver 170. Further, while the STB 150 and the TV receiver 170 are different devices, the operator may collectively refer to the STB 150 and the TV receiver 170 by using a term indicating the TV receiver 170 such as "television". Even in such a case, if the STB 150 is more suitable for the operation of the operator, the STB 150 can control the TV receiver 170.

Further, among the tuners 151 and 171 it is possible to determine a tuner having a higher resolution, that is, a control entity corresponding to a tuner suitable for displaying an image from the viewpoint of resolution. Further, when the resolution of the tuner 151 of the STB 150 is higher than the resolution of the tuner 171 of the TV receiver 170, the STB 150 becomes the control main body. Therefore, in this case, the TV receiver 170 is compared with the case where the infrared device 160 becomes the control main body. The resolution of the image displayed in is increased. For example, when the resolution of the tuner 151 of the STB 150 is 4K resolution and the resolution of the tuner 171 of the TV receiver 170 is 2K resolution, when the infrared device 160 becomes the control main body, the image of the 2K resolution received by the tuner 171 is displayed. A 2K resolution image is displayed according to the broadcast wave for the purpose. However, in this case, when the STB 150 becomes the control subject, a 4K resolution image is displayed according to the 4K broadcast wave received by the tuner 151. On the contrary, when the resolution of the tuner 171 of the TV receiver 170 is higher than the resolution of the tuner 151 of the STB 150, the infrared device 160 becomes the control main body. Therefore, in this case, the TV receiver is compared with the case where the STB 150 becomes the control main body. The resolution of the image displayed on the 170 is increased.

Further, since the infrared device 160 performs infrared communication, even if the TV receiver 170 has only one insertion port for the communication line 190 for the control device, a plurality of TV receivers 170 can be connected to the TV receiver 170. A control device can be provided. Further, since the STB 150 identifies the control subject and transfers the control instruction, the infrared device 160 does not have to perform a process of determining whether or not the own device is the control subject.

3. 3. Modified Examples The above-described embodiment is merely an example of the present invention, and the present invention is not limited thereto. Various modifications may be made to the above-described embodiment. For example, the above-described embodiment may be modified as follows. Further, the following modified examples may be used in combination with one or more other modified examples.

3.1. Modification 1
In the above-described embodiment, the elements used in determining the control subject are not limited to the resolutions of the tuners 151 and 171. For example, the control subject may be determined by the presence or absence of a content viewing contract. For content for which a viewing contract has not been concluded, the content is not displayed even if the operator performs an operation instructing the display of the content. For example, suppose that the operator performs a voice operation instructing the display of the BS broadcast image by emitting the voice "Turn on the first broadcasting station of BS". In this case, if a BS broadcast viewing contract is concluded for the operator, STB150 may be determined as the control subject. When the STB 150 is determined to be the control subject, the tuner 151 of the STB 150 receives the broadcast wave of the BS broadcast, and the TV receiver 170 displays the image of the BS broadcast. By this process, the operator can watch the image of the BS broadcast. On the other hand, if the viewing contract for the BS broadcast content is not concluded for the operator, the infrared device 160 may be determined as the control subject.

In addition, when the operator emits a voice saying "Show me one channel" and performs a voice operation instructing the display of the contents of the terrestrial digital television broadcast, the control subject is that the STB150 is within the retransmission area of the terrestrial digital television broadcast. It may be determined by whether or not it is installed in. When the STB 150 is installed outside the retransmission area of the terrestrial digital television broadcast, the TV receiver 170 cannot display the image corresponding to the broadcast wave of the terrestrial digital television broadcast by using the tuner 151 of the STB 150. However, even in this case, the tuner 171 of the TV receiver 170 can be used to display the image corresponding to the broadcast wave of the terrestrial digital television broadcast on the TV receiver 170. For example, when the STB 150 is installed in the retransmission area of the terrestrial digital television broadcast, the STB 150 may be determined as the control subject. When the STB 150 is determined to be the control entity, the tuner 151 of the STB 150 receives the broadcast wave of the terrestrial digital television broadcast, and the TV receiver 170 displays the image of the terrestrial digital television broadcast. On the other hand, when the STB 150 is installed outside the retransmission area of the terrestrial digital television broadcast, the infrared device 160 may be determined as the control subject. When the infrared device 160 is determined to be the control entity, the tuner 171 of the TV receiver 170 receives the broadcast wave of the terrestrial digital television broadcast, and the TV receiver 170 displays the image of the terrestrial digital television broadcast. According to this process, the operator can watch the video of the terrestrial digital television broadcast regardless of whether or not the STB 150 is installed in the retransmission area of the terrestrial digital television broadcast.

Further, the control subject may be determined by the screen on which the TV receiver 170 is displaying. When the TV receiver 170 is displaying the image using the tuner 171, in order to display the image using the tuner 151 of the STB 150, the image corresponding to the image signal supplied from the STB 150 via the communication line 190 is used. It is necessary to switch the input so that is displayed. On the contrary, when the TV receiver 170 is displaying the screen provided by the STB 150, in order to display the image using the tuner 171, the image corresponding to the image signal supplied from the tuner 171 is displayed. It is necessary to switch the input as follows. Therefore, for example, when the TV receiver 170 is displaying the screen provided by the STB 150, the STB 150 may be determined as the control subject. When the STB 150 is determined to be the control subject, the TV receiver 170 is switched from the screen provided by the STB 150 to display an image using the tuner 151 of the STB 150. On the other hand, when the TV receiver 170 is displaying other screens, the infrared device 160 may be determined as the control subject. When the infrared device 160 is determined to be the control subject, the TV receiver 170 is switched from the screen displayed on the TV receiver 170 to display an image using the tuner 171.

Further, the control subject may be determined by the content of the operation of the operator. For example, when the operator emits a voice "turn up the volume" and performs a voice operation instructing the change of the volume of the TV receiver 170, the infrared device 160 may be determined as the control subject. Alternatively, in this case, the STB 150 may be determined as the control subject, but in that case, a control signal for controlling the STB 150 to change the volume is transmitted to the TV receiver 170, and the TV receiver 170 follows this control signal. Changes the volume. Further, the control subject may be determined from at least two combinations of the plurality of elements described above.

3.2. Modification 2
In the above-described embodiment, when the control signal is transmitted from the infrared device 160 and the control signal has not reached the TV receiver 170, the control subject may be switched from the infrared device 160 to the STB 150. For example, when there is a shield between the infrared device 160 and the TV receiver 170, the control signal transmitted from the infrared device 160 does not reach the TV receiver 170. In this case, the control signal is not received by the TV receiver 170, and the TV receiver 170 does not operate according to the control signal. In this modification, the input / output terminal 110 acquires the environmental sound including the sound of the TV receiver 170, converts it into an audio signal, and transmits it to the management server 140. As shown in FIG. 7, the management server 140 has a arrival determination unit 244 in addition to the functional configuration shown in FIG.

When the infrared device 160 is determined as the control subject, the arrival determination unit 244 inputs / outputs when the infrared device 160 transmits a control signal (hereinafter, referred to as “previous control signal”) in response to an instruction from the instruction unit 243. From the change in the sound of the TV receiver 170 indicated by the audio signal received from the terminal 110, it is determined whether or not the previous control signal has reached the TV receiver 170. Here, first, it is assumed that the previous control signal controls to change the channel. FIG. 8 is a diagram showing an example of a change in the volume of the TV receiver 170 according to this modified example. In FIG. 8, the vertical axis represents the volume of the TV receiver 170, and the horizontal axis represents the time. When the channel is changed according to the previous control signal, as shown in FIG. 8, the time t2 at which the volume becomes the predetermined volume v1 or less within a predetermined period from the time t1 when the previous control signal is transmitted is the number. Occurs for a second. This predetermined volume v1 is, for example, a volume that can be regarded as silence. Therefore, when the sound of the TV receiver 170 has a change pattern as shown in FIG. 8 in response to the transmission of the previous control signal, it is determined that the previous control signal has reached the TV receiver 170. On the other hand, if the sound of the TV receiver 170 does not have the change pattern as shown in FIG. 8 in response to the transmission of the previous control signal, it is determined that the previous control signal has not reached the TV receiver 170. Will be done.

Next, suppose that the previous control signal controls to raise the volume. FIG. 9 is a diagram showing another example of a change in the volume of the TV receiver 170 according to this modified example. In FIG. 9, the vertical axis shows the volume of the TV receiver 170, and the horizontal axis shows the time. When the volume is raised according to the previous control signal, the volume is raised within a predetermined period from the time t1 when the previous control signal is transmitted, as shown in FIG. Therefore, when the sound of the TV receiver 170 has a change pattern as shown in FIG. 9 in response to the transmission of the previous control signal, it is determined that the previous control signal has reached the TV receiver 170. On the other hand, when the sound of the TV receiver 170 does not have the change pattern as shown in FIG. 9 in response to the transmission of the previous control signal, it means that the previous control signal has not reached the TV receiver 170. It is judged. The determination result of the arrival determination unit 244 is supplied to the instruction unit 243.

When the arrival determination unit 244 determines that the previous control signal has not reached the TV receiver 170, the instruction unit 243 instructs the STB 150 to transmit a control signal having the same content as the previous control signal to the TV receiver 170. To do. For example, the instruction unit 243 generates a control instruction including an instruction indicating the same control content as the previous control signal and an identifier of the STB150, and transmits the control instruction to the STB150. By this process, the control signal having the same content as the previous control signal is retransmitted from the STB 150 to the TV receiver 170. According to this modification, the TV receiver 170 can be controlled even when the control signal transmitted from the infrared device 160 using a wireless medium such as infrared rays cannot reach the TV receiver 170.

3.3. Modification 3
In the above-described embodiment, when a plurality of TV receivers 170 are provided, it may be automatically determined whether or not the STB 150 and the infrared device 160 are connected to the same TV receiver 170. Note that this process may be performed before, for example, the operation of the above-described embodiment. In this case, the instruction unit 243 instructs the infrared device 160 to transmit a predetermined control signal according to the predetermined control content to the TV receiver 170. This predetermined control is, for example, control of a power supply. The infrared device 160 transmits a predetermined control signal to the TV receiver 170 in response to an instruction from the instruction unit 243. When the infrared device 160 transmits a predetermined control signal, the STB 150 detects the state of the TV receiver 170 and transmits the state information indicating the detected state to the management server 140. As shown in FIG. 10, the management server 140 has a target determination unit 245 in addition to the functional configuration shown in FIG.

The target determination unit 245 determines whether or not the control target of the STB 150 and the control target of the infrared device 160 are the same TV receiver 170 based on the state information received from the STB 150, that is, acquired. For example, in the case where a predetermined control signal is controlled to turn on the power, when the TV receiver 170 is turned on in response to the transmission of the predetermined control signal, the control target of the STB 150 and the infrared device It is determined that the control target of 160 is the same TV receiver 170. On the other hand, in this case, when the TV receiver 170 is not turned on in response to the transmission of the predetermined control signal, the control target of the STB 150 and the control target of the infrared device 160 are the same TV receiver. It is determined that it is not 170. The determination result of the target determination unit 245 is supplied to the determination unit 242.

The determination unit 242 determines the control subject from among a plurality of control devices that control the same TV receiver 170 based on the determination result of the target determination unit 245. For example, when it is determined that the control target of the STB 150 and the control target of the infrared device 160 are the same TV receiver 170, the control subject is selected from the STB 150 and the infrared device 160 as in the above-described embodiment. It is determined. According to this modification, even if a plurality of control devices that control the TV receiver 170 include a control device that controls different TV receivers 170, the same TV receiver 170 is controlled. Among the above control devices, a control device suitable for the operation of the operator can control the TV receiver 170.

The text may be input in a chat format.

3.5. Modification 5
In the above-described embodiment, the STB 150 and the TV receiver 170 do not necessarily have to be connected via the communication line 190. For example, the STB 150 and the TV receiver 170 may be connected by using a wireless medium. The wireless medium may be infrared, radio, visible, sound, or ultrasonic. Further, the communication method between the TV receiver 170 and the STB150 is not limited to HDMI, and other communication methods may be used.
