  Hereinafter, power consumption display and control of an external device by the power consumption display system according to the first and second embodiments will be described.

(First power consumption display)
The communication module 103 of the DTV 1 receives power consumption information from each external device. The OSD control module 107 of the DTV 1 generates display information for relatively displaying the power consumption of each external device based on the power consumption information of each external device, and the composition processing module 109 outputs the display information. Correspondingly, the video display unit 1b relatively displays the power consumption of each external device based on the display information.

  FIG. 2 is a diagram illustrating an example of the power consumption display of each external device. For example, as shown in FIG. 2, the video display unit 1b displays the power consumption ratio of each external device in a graph (for example, a pie chart 11), and also displays the total power consumption of each external device. Furthermore, the video display unit 1b displays a pointer (for example, a free cursor 12) for selecting an external device to be controlled. The pie chart 11 includes an icon corresponding to each external device and a power consumption value of each external device. Thereby, the user can grasp | ascertain intuitively the ratio of the power consumption of each external device in the power consumption of all the apparatuses.

  Note that the DTV 1 may change the size of the icon of each external device according to the power consumption of each external device and relatively display the power consumption of each external device. For example, the icon of an external device with very high power consumption is displayed very large, the icon of an external device with slightly high power consumption is displayed with a large size, and the icon of an external device with low power consumption is displayed with a small size. You may make it display the icon of the external apparatus with very small electric power very very small.

(First external device control)
The DTV 1 can control the selected external device in response to the selection operation of the external device. For example, the user can select an external device to be controlled via the power consumption display screen (for example, FIG. 2) using the cursor control pad 1021 (free cursor 12) of the remote controller 102a. The control module 104 of the DTV 1 instructs the output of the control menu 13 (see FIG. 3) for controlling the selected external device in response to the selection operation of the external device. In response to this instruction, the OSD control module 107 generates display information, and the composition processing module 109 outputs the display information. Correspondingly, as shown in FIG. 3, the video display unit 1b relatively displays the power consumption of each external device based on the display information, and controls the control menu 13 for controlling the selected external device. Is displayed.

  The control menu 13 includes items (controllable items) corresponding to the corresponding external device. The communication module 103 receives information about controllable items from each external device, and the OSD control module 107 displays a control menu corresponding to each external device based on information about controllable items from each external device. Display information can be generated.

  When the selected external device is, for example, an air conditioner, the control menu 13 corresponding to the selected external device includes the name of the external device to be controlled (air conditioner), power (power-on state / power-off state), Includes information such as set temperature and operation mode. For example, the user can select an item of power via the control menu 13 using the cursor control pad 1021 (free cursor 12) of the remote controller 102a. The control module 104 of the DTV 1 instructs the output of the control menu 14 (see FIG. 4) for controlling power in response to the power item selection operation. In response to this instruction, the OSD control module 107 generates display information, and the composition processing module 109 outputs the display information. In response to this, the video display unit 1b displays a control menu 14 for controlling power.

  The control menu 14 includes items of ON and OFF, for example. For example, the user can select an ON or OFF item via the control menu 14 using the cursor control pad 1021 (free cursor 12) of the remote controller 102a. The control module 104 of the DTV 1 instructs the output of a power control signal (power OFF control signal) for controlling power in response to, for example, an OFF item selection operation. In response to this instruction, the communication module 103 outputs a power control signal (power OFF control signal) to the external device to be controlled.

  For example, the external device to be controlled receives the power control signal, and switches from the operating power supply state to the standby power supply state to enter the standby state.

(Second power consumption display)
The external device that has switched from the operating state to the standby state notifies the DTV 1 that it is in the standby state. The control module 104 of the DTV 1 executes control for distinguishing and displaying the external device in the standby state and the external device in the operation state based on the standby state notification. In response to this, the OSD control module 107 Display information for relatively displaying the power consumption of the external device in the operation state and distinguishing the external device in the operation state from the external device in the standby state is generated, and the synthesis processing module 109 outputs the display information. In response to this, as shown in FIG. 5, for example, the video display unit 1b relatively displays the power consumption of the external device in the operating state and distinguishes the external device in the operating state from the external device in the standby state. Separately displayed.

  As shown in FIG. 5, the power consumption of the external device in the operating state is displayed by the pie chart 11, the external device in the standby state is not displayed in the pie chart 11, and the external device in the standby state is displayed in the standby list area 15. Is done. With this display, the user can intuitively identify the external device in the operating state and the external device in the standby state.

(Second external device control)
The DTV 1 can control the selected external device in the standby state in response to the selection operation of the external device in the standby state. For example, the user can use the cursor control pad 1021 (free cursor 12) of the remote controller 102a to select an external device in a standby state via a standby list area on a power consumption display screen (for example, FIG. 5). . The control module 104 of the DTV 1 instructs the output of the control menu 13 (see FIG. 6) for controlling the selected external device in the standby state in response to the selection operation of the external device in the standby state. In response to this instruction, the OSD control module 107 generates display information, and the composition processing module 109 outputs the display information. In response to this, the video display unit 1b displays a control menu 13 for controlling the selected external device in the standby state, as shown in FIG.

  For example, the user can select the ON item via the control menu 13 using the cursor control pad 1021 (free cursor 12) of the remote controller 102a. For example, the control module 104 of the DTV 1 instructs the output of a power control signal (power ON control signal) for controlling power in response to an ON item selection operation. In response to this instruction, the communication module 103 outputs a power control signal (power ON control signal) to the external device to be controlled. For example, the external device to be controlled receives a power control signal, and switches from a standby power supply state to an operating power supply state to enter an operation state.

  In addition, the user can select a set temperature item via the control menu 13 using the cursor control pad 1021 (free cursor 12) of the remote controller 102a. The control module 104 of the DTV 1 instructs the output of the control menu 16 (see FIG. 6) for controlling the set temperature in response to the selection operation of the set temperature item. In response to this instruction, the OSD control module 107 generates display information, and the composition processing module 109 outputs the display information. In response to this, the video display unit 1b displays a control menu 16 for controlling the set temperature.

  The control menu 16 includes, for example, items of temperature up and temperature down. For example, the user can set the temperature by selecting the item of temperature up or temperature down via the control menu 16 using the cursor control pad 1021 (free cursor 12) of the remote controller 102a. The control module 104 of the DTV 1 instructs the output of a temperature control signal for designating the temperature value set in response to the item selection of temperature up or temperature down. In response to this instruction, the communication module 103 outputs a temperature control signal to the external device to be controlled. For example, the external device to be controlled receives a temperature control signal and controls the temperature value.

(Third power consumption display)
In the above description, the case where the DTV 1 mainly displays the power consumption of each external device using a pie chart has been described. However, the display is not limited to the power consumption display of each external device by a pie chart.

  For example, as shown in FIG. 7, the video display unit 1b of the DTV 1 displays the power consumption ratio of each external device as a bar graph (for example, a horizontal bar graph 30), and also displays the total power consumption of each external device. That is, the video display unit 1b displays the stacked power consumption of each external device by the horizontal bar graph 30.

  For example, the user can use the cursor control pad 1021 (free cursor 12) of the remote controller 102a to select an external device to be controlled via the power consumption display screen (for example, FIG. 7). The control module 104 of the DTV 1 instructs the output of the control menu 13 (see FIG. 8) for controlling the selected external device in response to the selection operation of the external device. In response to this instruction, the OSD control module 107 generates display information, and the composition processing module 109 outputs the display information. Correspondingly, the video display unit 1b relatively displays the power consumption of each external device based on the display information and controls the control menu 13 for controlling the selected external device, as shown in FIG. Is displayed. The control of the external device via the control menu 13 is as described above.

(4th power consumption display)
The power consumption display by the power consumption display system shown in FIG. 9 will be described. As described above, the DTV 1 receives power consumption information from each external device, and also receives power consumption information (for example, power consumption information for the entire home) from the smart meter 6.

  Correspondingly, as shown in FIG. 10, for example, the video display unit 1b of the DTV 1 relatively displays the power consumption of each external device, displays the total power consumption of each external device, and further displays the entire home. The power consumption is also displayed.

  Next, acquisition of power consumption information by the DTV 1 will be described.

(First example of power consumption information acquisition)
For example, the DTV 1 polls each external device at a necessary timing, and acquires power consumption information from each external device.

  As illustrated in FIG. 12, the DTV 1 issues a power information acquisition request (power information acquisition command) to the external device 2 in order to acquire power consumption information from the external device 2. The external device 2 that has received the power information acquisition request measures its own current power information (power consumption), and returns a power information acquisition response to the power information acquisition request to the DTV 1. The power information acquisition response includes the current power consumption value of the external device 2.

  Through similar processing, the DTV 1 acquires the power consumption value from the external devices 3, 4, and 5.

(Second example of power consumption information acquisition)
For example, each external device notifies the DTV 1 of power consumption information (power consumption value) at the timing when the power consumption changes. In response to this, the DTV 1 acquires power consumption information from each external device.

  As illustrated in FIG. 13, the DTV 1 issues a power information notification request (power information notification command) to the external device 2 in order to acquire power consumption information from the external device 2. The power information notification request is a request for notifying power consumption information according to a change in power consumption. Similarly, the DTV 1 issues a power information notification request to the external devices 3, 4, and 5.

  The external device 2 that has received the first power information notification request measures its own current power information (power consumption), and returns a power information notification response to the power information notification request to the DTV 1. The power information notification response includes the current power consumption value of the external device 2. Similarly, the external device 3 that has received the first power information notification request measures its own current power information (power consumption), and returns a power information notification response to the power information notification request to the DTV 1. The power information notification response includes the current power consumption value of the external device 3.

  Thereafter, when a change occurs in the power consumption value, each external device transmits a power information notification including the changed power consumption value to the DTV 1.

  When the DTV 1 transmits a power information notification stop request to each external device, each external device returns a power information notification stop response and stops the power information notification. That is, each external device receives power information including a power consumption value that has changed with respect to the DTV 1 when a change occurs in the power consumption value from when the power information notification request is received until the power information notification stop request is received. Send information notifications.

(Third example of power consumption information acquisition)
For example, each external device notifies the DTV 1 of power consumption information (power consumption value) at regular intervals. In response to this, the DTV 1 acquires power consumption information from each external device.

  As illustrated in FIG. 14, the DTV 1 issues a power information notification interval setting request to the external device 2 in order to acquire power consumption information from the external device 2 at a first time interval. The power information notification interval setting request is a request to notify the power consumption information at the first time interval. Similarly, the DTV 1 issues a power information notification interval setting request to the external device 3 in order to acquire power consumption information from the external device 3 at the second time interval. The power information notification interval setting request is a request for notifying power consumption information at the second time interval. Similarly, a power information notification interval setting request is issued to the external devices 4 and 5.

  Receiving the first power information notification interval setting request, the external device 2 measures its own current power information (power consumption) and sends a power information notification interval setting response to the DTV 1 in response to the power information notification interval setting request. Send back. The power information notification interval setting response includes the current power consumption value of the external device 2. Similarly, the external device 3 that has received the first power information notification interval setting request measures its current power information (power consumption), and sends a power information notification interval setting response to the power information notification interval setting request as DTV1. Reply to The power information notification interval setting response includes the current power consumption value of the external device 3.

  Thereafter, each external device transmits a power information notification including a power consumption value to the DTV 1 at a set time interval.

  When the DTV 1 transmits a power information notification stop request to each external device, each external device returns a power information notification stop response and stops the power information notification. That is, each external device transmits a power information notification including a power consumption value to the DTV 1 at a set time interval after receiving a power information notification interval setting request and receiving a power information notification stop request. To do.

  In the above description, selection of an external device and selection of an item using a cursor has been described. Note that selection of an external device and selection of an item by selection means other than the cursor may be used. In the above description, various controls via the control menu have been described. Note that various types of control using designation means other than the control menu may be used. That is, various methods can be applied to the user interface.

  In the above description, the case where the DTV 1 displays the power consumption of each external device and controls the operation of each external device has been described. Similarly, a communication device such as a personal computer, a mobile phone, a smartphone, or a tablet terminal can display the power consumption of each external device and control the operation of each external device.

  In the above description, the case where the DTV 1 mainly uses wireless communication to display the power consumption of each external device and controls the operation of each external device has been described. Similarly, the DTV 1 or the communication device described above can be connected to each external device via Ethernet (registered trademark), PLC, or the like, display the power consumption of each external device, and control the operation of each external device.

  The power consumption display and external device control described in each embodiment will be summarized below.

  The DTV 1 can relatively and clearly notify the power consumption of each external device by at least one of the first to fourth power consumption displays. Thereby, the user can intuitively grasp the power consumption of each external device, and the convenience for the user is enhanced. Furthermore, the DTV 1 can simplify the operation for controlling each external device by combining the above display and the first and second external device controls, and can obtain the effect of promoting energy saving behavior. .

  For example, the DTV 1 displays the power consumption of each external device in a graph, and the user may select a desired external device from the graph display and turn off the power of the selected external device for energy saving. it can. In addition, in order to reduce the power consumption of the external device, the user may select a desired external device from the graph display to lower the heating set temperature of the selected external device or increase the cooling set temperature. it can.
