A group table and a preset table, in which group codes assigned to each zone are registered, and the preset table has a plurality of preset registration units selectable by an operating device; Storage means for registering broadcast signal selection data and a group code in each registration unit; When the preset registration unit is selected by the operating device, the group code registered in the registration unit matches the group code assigned to the zone in which the operating device is operated and is registered in the registration unit. When the registration presence / absence data is registered, the reception unit has a control means for selecting a broadcast signal based on the broadcast signal selection data registered in the registration unit.
It should be noted that when the registration presence / absence data indicating the presence / absence of registration is registered in each registration unit, and when the control unit selects the preset registration unit by the operation device, the group code registered in this registration unit is Is matched with the group code assigned to the operated zone, and the registration presence / absence data registered in the registration unit is registered, based on the broadcast signal selection data registered in the registration unit, the receiving device May select a broadcast signal.

  According to the present invention, a broadcast station can be easily selected.

  Hereinafter, an example of an embodiment in which the present invention is applied to an audio device will be described with reference to the drawings. As shown in FIG. 1, the audio device includes a radio receiver 1, speakers 2 to 4, and a remote control light receiver 5 to 5. 7 and a remote controller (not shown).

  The radio receiving device 1 includes a tuner 9, amplifiers 10 to 12, and a microcomputer 13. The radio receiving device 1 can be directly operated without a remote controller. The tuner 9 selectively receives a radio broadcast signal from a broadcast station, and is connected to the antenna 14 and outputs the received broadcast signal to the amplifiers 10 to 12. The amplifiers 10 to 12 amplify the broadcast signal and output it. The microcomputer 13 (microcontroller, system controller, control device, control means) controls the tuner 9, and is a central processing circuit (CPU) (not shown) that performs information processing and a read-only memory that stores a control program. A memory (ROM) (not shown) and a random access memory (RAM) (not shown) for storing variables necessary for processing are included.

  The speakers 2 to 4 and the remote control light receiving units 5 to 7 are arranged in a plurality of rooms exemplified as zones, and in the example shown in the figure, they may be referred to as a main room (this may be called a zone 1 (room)). ), Disposed in the zone 2 room and the zone 3 room, and connected to the amplifiers 10 to 12 or the microcomputer 13. In this example, the operating device is configured by the remote controller and the remote control light receiving units 5 to 7 that receive the infrared rays for instruction from the remote controller, and the radio receiving device 1 is operated via the microcomputer 13. The remote control has operation keys such as a pre-setup key for selecting a broadcasting station. In addition, as described above, the operating device may not be configured by two devices, but may be configured by a single device. In this example, the zone is a room, but the zone may be a simple place that is not clearly partitioned.

  By the way, for example, when the main room is a living room shared by parents and children, the zone 2 rooms are children's rooms, and the zone 3 rooms are parents' bedrooms, the radio broadcast programs listened to in each room Of course, this trend will be different. Therefore, a large number of broadcasting stations are divided into a group A for fathers, a group B for mothers, and a group C for children. The “group A” or “A” or the like is referred to as a group code in this example. When divided as described above, parents and children listen to broadcast programs belonging to groups A to C in the main room, and children play broadcast programs belonging to group C in the zone 2 room. The father listens to the broadcast program of the broadcasting station belonging to the group A in the zone 3 room. Originally, in the zone 3 room, the mother listens to the broadcast program of the broadcast station belonging to the group B, but this point is omitted for convenience of explanation.

  In consideration of the above, as shown in FIG. 2, in order to register the group code assigned to each zone in the RAM of the microcomputer 13 (other storage devices may be used. The same applies hereinafter). Group tables are provided. In each row of this table, group codes for each room, that is, A to C, are registered by operation of the remote controller or the radio receiver 1. In this example, group codes A to C are registered for the main room, group code C is registered in the zone 2 room, and group code A is registered in the zone 3 room.

  As shown in FIG. 3, the RAM of the microcomputer 13 is also provided with a preset table for registering (presetting) radio broadcast stations in advance, and this table has a plurality of rows selectable by the remote controller. There are preset registration units (a plurality) (N rows (N) in the example). In each registration unit, broadcast signal selection data, group code data, and preset (registration) presence / absence data indicating the presence / absence of preset (registration) are registered. Data and group code data are arranged side by side from left to right. In the illustrated example, the broadcast station frequency (for example, “80.0MNz”) is exemplified as the broadcast signal selection data, “Group A” is exemplified as the group code data, and “Present” ( “Present” is shown) or “None” (“No preset” is shown). Note that the frequency of the broadcasting station is normally registered in advance before the purchase of the audio device, and the group code data and registration presence / absence data are input by the remote controller, but the frequency of the broadcasting station is input by the radio receiver 1 or the remote controller. There is also. The audio device, for example, the radio receiver 1, has a zone 2 room ON / OFF setting function and a zone 3 room ON / OFF setting function. When these are set to OFF, for example, control by the microcomputer 13 or the like. Thus, broadcast signals are not supplied to the speaker 3 in the zone 2 room and the speaker 4 in the zone 3 room, and audio is not output from these speakers 3 and 4. When the above setting is set to ON, broadcast signals can be supplied to the speaker 3 in the zone 2 room and the speaker 4 in the zone 3 room, and audio can be output from the speakers 3 and 4. The ON / OFF setting is performed by a direct operation of the radio reception device 1 or a remote control. By providing a plurality of tuners, broadcast programs from different broadcast stations can be reproduced in each room (zone).

  Next, flowcharts for controlling the audio device will be described with reference to FIGS. In the following description, only the remote control operation in the main room will be described, but remote control operations in other rooms are performed in the same manner.

  First, remote control operation processing in each room will be described with reference to FIGS. 4 shows the remote control operation processing in the main room, FIG. 5 shows the remote control operation processing in the zone 2 room, and FIG. 6 shows the remote control operation processing in the zone 3 room. In step S1 (R1, T1), it is determined whether or not the remote control light receiving unit 5 in the main room has received infrared rays from the remote control. If NO, the control is terminated, and if YES, the process proceeds to step S2 (R2, T2), the main room reception flag is set, and the process proceeds to step S3 (R3, T3). In step S3 (R3, T3), the operation data corresponding to the operation key operated by the remote controller is stored in the RAM of the microcomputer 13, and the control ends.

  Next, processing for selecting a broadcasting station by a remote controller in each room will be described with reference to FIGS. 7 shows the process of selecting a broadcast station in the main room, FIG. 8 shows the process of selecting a broadcast station in the zone 2 room, and FIG. 9 shows the operation of selecting a broadcast station in the zone 3 room. Shows the processing. When an arbitrary row in the preset table is n, the broadcast station is selected by increasing n to “1” using the pre-setup key of the remote controller. 7 to 9, “preset [n] .preset” means “presence” of the preset presence / absence data in n rows of the preset table, and “preset [n] .group” means the group of n rows described above. “Preset [n] .frequency” means the frequency of the above n rows. “Zone [1] [A]” etc. means registration of the group code A for the main room of the group table.

  First, in step P1 (V1, M1), “1” is added to “n”, and the process moves to step P2 (V2, M2). "Is registered or not. If NO, the process returns to Step P1 (V1, M1). If YES, the process moves to Step P3 (V3, M3), and what is registered as the group code of the preset registration unit in the “n” row. To be judged. If “Group A” is registered, the process proceeds to Step P4 (V4, M4). If “Group B” is registered, the process proceeds to Step P5 (V5, M5), and “Group C” is registered. Then, the process proceeds to step P6 (V6, M6).

  In Step P4 (V4, M4), it is determined whether or not “A” is registered for the main room of the group table. If NO, return to step P1 (V1, M1), if YES, move to step P7 (V7, M7), read the frequency of the preset register in the “n” row, and based on this data, The tuner 9 of the radio receiver 1 performs radio broadcast signal selection and reception processing. In Step P5 (V5, M5), it is determined whether or not “B” is registered for the main room of the group table. If NO, the process returns to step P1 (V1, M1). If YES, the process proceeds to step P7 (V7, M7). In Step P6 (V6, M6), it is determined whether or not “C” is registered for the main room of the group table. If NO, the process returns to step P1 (V1, M1). If YES, the process proceeds to step P7 (V7, M7).

  Specifically, first, regarding the preset table, by operating the remote control or the radio receiver 1, for example, a preset registration unit in which the frequency of the radio broadcasting station that the father wants to listen to is selected, “Group A” is registered as group code data, a preset (registration) confirmation operation is performed, and “present” is registered as preset data. Similarly, the mother and the child also select a preset registration unit in which the frequency of the radio broadcast station that they want to listen to is recorded, and register “Group B” or “Group C” as the group code data. Confirm operation is performed, and “Present” is registered as the preset data.

  In this state, when the father, mother, and child want to listen to the radio broadcast in the main room, the radio receiver 1 is operated by the remote controller via the remote control light receiving unit 5. When the pre-setup key is operated, each preset registration section of the preset table is sequentially read out. In this case, the tuner 9 of the radio receiver 1 sequentially receives broadcast signals from the corresponding broadcast stations based on the frequency of the preset registration unit whose preset data is “present”, and outputs audio from the speaker 2. To go. Thereby, a desired radio broadcast station can be selected from broadcast stations pre-selected by the father, mother and child, and the broadcast program can be listened to. In this case, the ON / OFF setting of the zone 2 room and the zone 3 room may be set to OFF or ON.

  If the child wants to listen to the radio broadcast in the Zone 2 room, the ON / OFF setting for the Zone 2 room is set to ON, and the ON / OFF setting for the Zone 3 room is set to OFF. Similarly, the radio receiver 1 is operated by a remote controller. In this case, in the zone 2 room, the tuner 9 of the radio receiving apparatus 1 broadcasts the corresponding broadcast station based on the frequency of the preset registration unit in which the preset data is “present” and the group code data is “group C”. Signals are sequentially received and output from the speaker 3 as audio. Thereby, a desired radio broadcast station can be selected from the broadcast stations previously selected by the child, and the broadcast program can be listened to.

  Further, when the father wants to listen to the radio broadcast in the zone 3 room, the ON / OFF setting of the zone 2 room is set to OFF, and the ON / OFF setting of the zone 3 room is set to ON, and then the above Similarly, the radio receiver 1 is operated by a remote controller. In this case, in the zone 3 room, the tuner 9 of the radio receiving device 1 broadcasts the broadcast signal of the corresponding broadcast station based on the frequency of the preset registration unit having the preset “present” and the group code data “group A”. Are sequentially received and output from the speaker 4 as audio. Thereby, a desired radio broadcasting station can be selected from the broadcasting stations previously selected by the father, and the broadcast program can be listened to.
