The CPU stores information such as the html language of the data acquired from the dedicated server 400 or the web servers 500 and 600 in the RAM 16 or the nonvolatile memory 17.

In the digital broadcast receiving apparatus of the present invention, it is necessary to acquire living environment information for driving the air cleaner from the outside. In this embodiment, a case where pollen information is selected as living environment information will be described below. The same applies to the case where the drive signal for the air purifier 200 is generated based on other living environment information such as influenza epidemic information.
In the present invention, the digital broadcast receiving apparatus 100 acquires pollen information from BS / CS digital broadcast, terrestrial digital broadcast, or a dedicated server 400 or web servers 500 and 600 connected to the Internet.

First, when pollen information is acquired from BS / CS digital broadcasting or terrestrial digital broadcasting, a program such as a weather forecast broadcasting pollen information is received, and the data is stored in the transport stream data of the broadcast signal of the received broadcast channel. Information on pollen information is acquired from the content for data broadcasting included as a signal.
Normally, contents such as weather forecast information and pollen information are described as BML (Broadcast Markup Language) documents for screen display, and by analyzing this, pollen information in each region can be known.

  For this reason, the digital broadcast receiving apparatus 100 needs to have program information indicating in which time zone data broadcasting regarding pollen information is performed. For example, these pieces of information can be obtained from the electronic program guide described above, or can be provided from the dedicated server 400 connected via the Internet network 300, or by using a predetermined channel. Can be broadcast regularly. Then, information indicating when and in which program data broadcasting regarding pollen information is performed may be stored in, for example, the nonvolatile memory 17.

  FIG. 3 is a pollen information table showing the amount of pollen for each region and for each day in a table format. This pollen information table 30 can be created by analyzing data related to pollen information from data broadcasting contents by an application program stored in the ROM 15, and the result is developed in, for example, the nonvolatile memory 17. be able to. The pollen information table 30 only needs to know at least information on the amount of pollen on the day, and data for several days ahead may not be known.

Next, when pollen information is acquired from the dedicated server 400 connected to the Internet or the web servers 500 and 600, it is acquired from a web page on which pollen information in a predetermined website provided by these servers is posted. Is possible.
For this reason, the digital broadcast receiving apparatus 100 needs to have URL information of an access destination of which server's website the pollen information is provided, but the dedicated server 400 provides the pollen information itself. In addition, the dedicated server 400 may provide these URL information, or the user can set the URL information in the digital broadcast receiving apparatus 100.

  Then, the digital broadcast receiving apparatus 100 accesses a web page on which the pollen information is posted on the dedicated server 400 and the web servers 500 and 600, acquires html data describing the data related to the pollen information, and analyzes it. The above-described pollen information table 30 can be created.

  In addition, since pollen information is provided for each region, in order to obtain pollen information in a region where the digital broadcast receiving device 100 is installed, the digital broadcast receiving device 100 must have information on its own installation location. Usually, at the time of initial setting of the digital broadcast receiving apparatus 100, the user has already input the area information or the zip code in order to select a terrestrial digital broadcast that can be received, and the RAM 16 or the nonvolatile memory 17 has the area information of the installation location. Since it is recorded, by using this area information, it is possible to obtain information on the amount of pollen in the area of use from the pollen information table 30.

  In addition, when the digital broadcast receiving apparatus 100 acquires pollen information from the dedicated server 400, the digital broadcast receiving apparatus 100 is directly inquired of the dedicated server 400 about the amount of pollen without accessing the web page. The pollen information of the area where the “” is installed may be acquired from the dedicated server 400. In this case, the above-mentioned pollen information table needs to be prepared on the dedicated server 400 side. The request and distribution of data for pollen information acquisition can be executed by a dedicated application program installed in the digital broadcast receiving apparatus 100 and the dedicated server 400.

Next, an example of generating a drive signal for the digital broadcast receiving apparatus 100 to operate the air purifier 200 based on pollen information obtained from the outside will be described.
FIG. 4 is a drive condition table that defines the relationship between the amount of pollen and the drive condition of the air cleaner for each operation mode of the air cleaner. These tables are recorded in advance in the RAM 16 or the nonvolatile memory 17.

The drive condition table 41 shown in FIG. 4A shows the relationship between the amount of pollen and the amount of air when the air purifier 200 is driven in the continuous operation (24-hour operation) mode. For example, when the amount of pollen on the day is “slightly large”, it indicates that it is necessary to generate a drive signal in which the air volume of the air purifier 200 is set to “medium”.
Moreover, the driving condition table 42 shown in FIG. 4B shows the relationship between the amount of pollen and the driving time per hour when the air purifier 200 is driven in the intermittent operation mode with a predetermined air volume. For example, when the amount of pollen on that day is “very large”, it indicates that it is necessary to generate a drive signal in which the drive time per hour of the air purifier 200 is set to 40 minutes.

The drive condition table 43 shown in FIG. 4C is a relationship between the amount of pollen and how many hours the air cleaner 200 should be continuously driven with a predetermined air volume in order to obtain a clean indoor space. When the amount of pollen is “large”, this indicates that the air cleaner 200 needs to be continuously operated for 2 hours.
In addition, since values, such as the drive time in these drive condition tables 41-43, change with the capacity | capacitance of the air cleaner 200, and the magnitude | size of the indoor space to install, the capacity | capacitance of the air cleaner 200 and the size of the room to be used. Multiple drive condition tables are stored so that they can be selected according to the size, and according to the input of the capacity of the air cleaner (for tatami mats, etc.) and the size of the room to be used (how many tatami mats) from the user, It is desirable for the CPU 12 to make a selection.

FIG. 5 is a diagram showing a flow when the user sets the operating condition of the air cleaner, and FIG. 6 shows a selection screen displayed on the digital broadcast receiver when setting the operating condition of the air cleaner. FIG.
The user operates a remote controller provided for the digital broadcast receiving device by key operation, and transmits a predetermined command to the CPU 12 via the input I / F 19, and the CPU 12 executes the program in the ROM 15 and the nonvolatile memory in accordance with the remote controller operation. 17 is called to create each selection screen of FIG. 6 and display it on the display unit 10.

  First, in step S <b> 1, the user selects what living environment information is to be operated in order to automatically operate the air purifier 200. In this case, the user causes the living environment information selection screen 51 shown in FIG. 6A to be displayed on the display unit 10 of the digital broadcast receiving apparatus 100 by performing predetermined key operations on the remote controller. Then, by operating the up and down keys of the remote controller, for example, after selecting pollen information, the user presses the determination key on the remote controller to select the pollen information as living environment information.

Next, in step S2, the user selects an acquisition source of living environment information. in this case,
After selecting the living environment information on the living environment information selection screen 51 in FIG. 6A, the living environment information acquisition destination screen 52 in FIG. 6B may be automatically displayed. On the living environment information acquisition destination screen 52, for example, the user can select terrestrial digital broadcasting, BS broadcasting, CS broadcasting, the Internet, or the like as an acquisition destination of pollen information.
It should be noted that acquisition sources that cannot be selected by the user due to contracts, such as CS broadcasting, are preferably made incapable of being selected by the user's remote control operation, such as being displayed in gray. In the case of acquiring from the Internet, although not shown, various display formats may be adopted, such as enabling selection from a case of acquiring from a general web server and a case of acquiring from a dedicated server. it can.

Next, in step S3, the operation mode of the air cleaner 200 is selected. In this case, after the acquisition destination is determined on the living environment information acquisition destination selection screen 52 in FIG. 6B, the operation mode selection screen 53 in FIG. 6C may be automatically displayed. In the operation mode selection screen 53, in the present embodiment, any one of continuous operation, intermittent operation, and reserved operation can be selected. Here, the continuous operation mode is a mode in which the air cleaner 200 is operated for 24 hours, and the intermittent operation mode is a mode in which the operation and stop of the air cleaner 200 are repeated.
When the user selects the continuous operation mode, the CPU generates a drive signal for the air purifier 200 using the drive condition table 41 described above. Further, when the intermittent operation mode is selected, the driving condition table 42 is used, and when the reserved operation mode is selected, the driving condition table 43 is used.

Next, when the reserved operation mode is selected in step S4, the process proceeds to step S5, where the user sets a timer by inputting a desired date and time from a reservation date and time determination screen (not shown), and the setting flow is ended. To do. The timer is one of the functions that the digital broadcast receiving apparatus 100 normally has, and can be used. The setting flow is also ended when the continuous operation mode or the intermittent operation mode is selected in step S4.
Note that the selection of the living environment information in step S1, the selection of the information acquisition destination in step S2, and the selection of the operation mode in step S3 are not limited to the order shown in FIG. Further, the reservation operation mode may be selected directly by a user's remote control operation regardless of the flow of FIG. Details of the reserved operation mode will be described later.

  The digital broadcast receiving apparatus 100 according to the present invention obtains living environment information for operating the air purifier from the outside according to the conditions set by the user, and drives for operating the air purifier based on the living environment information. A specific example for generating a signal will be described below.

(Specific example 1)
As operating conditions of the air purifier 200, for example, when pollen information is selected as the living environment information, terrestrial digital broadcasting is selected as the acquisition destination of the living environment information, and continuous operation is selected as the operation mode, first, the digital broadcast receiving device 100 is: Using the program information of the data broadcast relating to the pollen information stored in the nonvolatile memory 17, the corresponding program of the terrestrial digital broadcast is received within the broadcast time of the program providing the pollen information. Then, the pollen information table 30 is created by the method described above from the data broadcast regarding the received pollen information, and stored in the nonvolatile memory 17.

Next, the digital broadcast receiving apparatus 100 acquires the pollen amount in the corresponding area from the installation area information of the television 100 that the digital broadcast receiving apparatus 100 has. For example, if the current date is March 10 within Tokyo's 23 wards, information that the amount of pollen is “somewhat high” is obtained from the pollen information table 30 in FIG. 3.
Next, the digital broadcast receiving apparatus 100 refers to the driving condition table 41 corresponding to the continuous operation mode, and selects “medium”, which is the driving condition of the air purifier 200 when the pollen amount is “slightly large”. Then, a drive signal for continuously operating the air cleaner 200 with the air volume “medium” is generated, and the air cleaner 200 is driven.

Here, when the air cleaner 200 is built in the digital broadcast receiving apparatus 100, the CPU 12 may be configured to perform various controls of the air cleaner 200, or separately. A CPU or the like may be provided. In this case, the digital broadcast receiving apparatus 100 may transmit a drive signal to the air cleaner 20 by wire.
When the air cleaner 200 is installed indoors separately from the digital broadcast receiving device 100, the drive signal is transmitted by wire or wirelessly, for example, by infrared communication via the input / output I / F 18. Just tell 200.

(Specific example 2)
Next, the reservation operation mode will be described. The reserved operation mode is used, for example, when it is desired to clean indoor air when returning home when going out.
When the reserved operation is selected on the operation mode selection screen 53 in FIG. 6C and the date and time is set in step S5 in FIG. 5, the digital broadcast receiving apparatus 100 starts the air purifier from a predetermined time before the set date and time. A drive signal for driving 200 is generated.

  As operating conditions of the air purifier 200, for example, pollen information is selected as the living environment information, terrestrial digital broadcasting is selected as the acquisition destination of the living environment information, and reserved driving is selected as the driving mode. When the reservation date is March 10, the digital broadcast receiving apparatus 100 creates the pollen information table 30 and acquires the amount of pollen at the installation location in the same manner as in the first specific example. is there. However, in the reserved operation mode, the time at which the digital broadcast receiving apparatus 100 creates the latest pollen information table 30 is at least before the longest drive time in the drive condition table 43 in FIG. 4 from the reservation setting time. It is desirable. In this specific example, the pollen information table 30 may be created by 1 pm 4 hours before 5 pm on March 11.

Here, if the information that the amount of pollen on March 11 in the 23 wards of Tokyo is “large” is obtained, the digital broadcast receiving apparatus 100 refers to the drive condition table 43 and the amount of pollen is A drive time value “2 hours” corresponding to “many” is obtained. Then, the digital broadcast receiving apparatus 100 generates a drive signal for driving the air purifier 200 from 3:00 pm, which is “2 hours” before 5:00 pm on March 11, which is the reservation setting date and time. Tell the machine 200.
Thereby, the indoor air can be cleaned at 5:00 pm when the user returns home.

As described above, in one embodiment according to the present invention, pollen information has been described as an example of living environment information.For example, about the epidemic degree of influenza, it can be grasped from the number of patients by region announced from public health centers in each region, It is possible to generate a drive signal for the air cleaner from the number of patients by region. In addition, it is possible to generate a drive signal for the air cleaner based on various living environment information such as the amount of yellow sand and the epidemic of other infectious diseases.
Further, as described above, information that cannot be obtained from the broadcast signal as living environment information from the outside can be dealt with by providing a dedicated server.
Needless to say, the present invention can be suitably applied to display devices in addition to television devices as long as they can receive digital broadcasts.
