  Embodiments of the present invention will be described below with reference to the drawings. Here, an example will be described in which a remote control device for a DVD device is searched using the DVD device and a mobile phone.

  FIG. 1 is a schematic configuration diagram of a DVD device and a remote control device according to an embodiment of the present invention. However, for DVD equipment, a configuration related to searching for a remote control device is shown, and a configuration related to DVD playback or the like is omitted.

  The DVD device 100 according to the embodiment of the present invention includes an operation unit 1, a storage unit 2, an OSD (On Screen Display) unit 3, an infrared transmission unit 4, a rotation drive unit 5, and an infrared reception unit 6. And a control unit 7. The operation unit 1 has various keys, one of which is a remote control device search key. The storage unit 2 is for storing various setting information. The OSD unit 3 generates an OSD image signal and outputs it to an external display device. The infrared transmission unit 4 includes an infrared LED (not shown) and the like, and transmits a specific command for searching for a remote control device as an infrared signal. The rotation drive unit 5 includes a motor, a rotation mechanism, and the like, and rotates the infrared LED (not shown). The infrared receiver 6 receives the infrared signal, converts the infrared signal into a remote control code, a reply signal and setting information described later, and outputs the converted signal.

  In addition, the remote control device 200 according to the embodiment of the present invention includes an infrared receiver 8, an infrared transmitter 9, a power supply 10, a switch 11, an operation unit 12, a sound generator 13, and a controller 14. And. The infrared receiver 8 receives an infrared signal, converts the infrared signal into a command, and outputs the command. The infrared transmitter 9 converts a remote control code and a reply signal and setting information, which will be described later, into an infrared signal and outputs the infrared signal.

  The power source 10 is a power source that supplies power to each unit including the infrared receiving unit 8. The switch 11 is a switch for switching on / off the power supply from the power source 10 to the infrared receiving unit 8, and the on / off is controlled by the control unit 14. The operation unit 12 has various keys and a search mode setting switch to be described later. The sound generation unit 13 includes a speaker or the like, and generates sound based on a sound signal from the control unit 14.

  When an operation for operating the DVD device 100 is performed on the operation unit 12 of the remote control device 200, the control unit 14 outputs a remote control code corresponding to the operation to the infrared transmission unit 9, and the infrared transmission unit 9 outputs the remote control code. Convert to infrared signal and output to the outside. Then, the infrared receiving unit 6 of the DVD device 100 receives the output infrared signal, converts it into a remote control code and outputs it to the control unit 7, and the control unit 7 performs control corresponding to the remote control code. Performs an operation corresponding to the operation in the remote control device 200.

  Further, the operation unit 12 of the remote control device 200 has the search mode setting switch as described above, and this switch is a slide switch. In the vicinity of the search mode setting switch, “OFF”, “10 seconds”, “20 seconds”, “30 seconds”, “40 seconds” are displayed, and the search mode setting switch can be slid to a position corresponding to each display. it can.

  When the search mode setting switch is slid to any position on the time display other than “OFF”, the control unit 14 turns on for a predetermined time and turns off for the time display where the search mode setting switch is located. Control is performed so that the switch 11 repeats, and power is intermittently supplied to the infrared receiver 8, and the infrared signal cannot be received for the time indicated by the time for which the infrared signal can be received and the search mode setting switch is located for a predetermined time. The remote control device 200 repeats this state (search mode on state). When the infrared receiving unit 8 receives an infrared signal as a specific command from the infrared transmitting unit 4 of the DVD device 100 when the infrared signal can be received, the control unit 14 recognizes the specific command and receives a predetermined command. The sound signal is output to the sound generator 13, and the sound generator 13 generates sound. At this time, the control unit 14 outputs a reply signal to the infrared transmission unit 9, and the infrared transmission unit 9 outputs the reply signal to the outside as an infrared signal. Such intermittent operation of the remote control device 200 suppresses power consumption of the remote control device 200.

  Further, when the search mode setting switch is slid to the position corresponding to “OFF”, the control unit 14 controls the switch 11 to be always off, and the infrared receiving unit 8 is not always supplied with power, and the remote control device. 200 is always in an infrared signal unreceivable state (search mode off state). In this state, power consumption can be further suppressed as compared with the above-described search mode on state.

  In addition, various keys included in the operation unit 12 of the remote control device 200 include predetermined keys for notifying the DVD device 100 of the search mode setting state of the remote control device 200. When the predetermined key is depressed, the control unit 14 sets the search mode setting switch to a position other than “OFF”, and sets the search mode setting switch to a position other than “OFF” if the search mode setting switch is in the “OFF” position. For example, the setting information indicating the setting time of the time display at which the switch is located is output to the infrared transmission unit 9, and the infrared transmission unit 9 converts the setting information from the control unit 14 into an infrared signal and outputs the infrared signal to the outside. When the infrared receiving unit 6 of the DVD device 100 receives the infrared signal, the infrared signal is converted into setting information and output to the control unit 7, and the control unit 7 stores the setting information in the storage unit 2 (hereinafter, referred to as “infrared signal”). This setting information is referred to as search mode setting information).

  Next, the search for the remote control device 200 by the DVD device 100 will be described with reference to the flowchart shown in FIG. Here, it is assumed that the search mode setting information is stored in advance in the storage unit 2 of the DVD device 100 as described above.

  First, when the remote control device search key included in the operation unit 1 of the DVD device 100 is pressed, the control unit 7 detects this in step S20, and proceeds to step S21.

  In step S21, the control unit 7 confirms the search mode setting information stored in the storage unit 2. If the search mode setting information indicates the set time and the remote control device 200 is in the search mode on state (step S22). Y), the process proceeds to step S23.

  In step S23, the control unit 7 starts continuous output of a specific command to the infrared transmission unit 4, and the infrared transmission unit 4 starts continuous transmission of an infrared signal as a specific command. Thereafter, the infrared transmitter 4 continuously transmits the command until the set time indicated by the search mode setting information has elapsed at the longest.

  Here, when the remote control device 200 is in the search mode on state as described above, if the remote control device 200 receives a specific command from the DVD device 100 when the infrared signal can be received, the remote control device 200 outputs a sound. Generated and output a reply signal to the outside as an infrared signal.

  After step S23, if the infrared receiver 6 receives an infrared signal as a reply signal from the remote control device 200 by command transmission before the set time indicated by the search mode setting information has elapsed, and the controller 7 recognizes the reply signal. If the command is output to the infrared transmission unit 4 (Y in step S24), the command is stopped, and the process proceeds to step S29 where the OSD unit 3 generates an OSD image signal according to an instruction from the control unit 7 and displays the external display. Output to the device. Then, the display device displays that the remote control device has been searched.

  In addition, after step S23, even if the command is transmitted for the set time indicated by the search mode setting information, the remote control device 200 is not in a position where the command can be received, and the infrared receiving unit 6 receives the infrared signal as a reply signal. If the controller 7 cannot recognize the return signal (N in step S24), the process proceeds to step S25. If the entire searchable range is not searched (N in step S25), the process proceeds to step S27. In step S27, the rotation drive unit 5 rotates the infrared LED of the infrared transmission unit 4 by a predetermined angle according to an instruction from the control unit 7. Then, the process returns to step S23, and the continuous transmission of the specific command is resumed.

  Thereafter, the remote controller 200 is searched while the infrared LED of the infrared transmitter 4 is rotated by a predetermined angle, and when the entire searchable range is searched (Y in step S25), the process proceeds to step S26, and control is performed. In response to an instruction from the unit 7, the OSD unit 3 generates an OSD image signal and outputs it to an external display device. Then, the display device displays that the remote control device has not been searched.

  If the search mode setting information is confirmed in step S21 and the search mode setting information indicates that the search mode is off (N in step S22), the process proceeds to step S28, and the OSD unit 3 causes the OSD image signal to be transmitted according to an instruction from the control unit 7. Is generated and output to an external display device. Then, the display device displays that the remote control device is in the search mode off state.

  As described above, if the remote control device 200 is in the search mode ON state and is in a position where the command transmitted from the DVD device 100 can be received, the remote control device 200 generates sound, so the user searches for the remote control device 200. (At this time, the display in step S29 is performed on the display device).

  However, even if the remote control device 200 is in the search mode on state, if the command transmitted from the DVD device 100 is not in a position where it can be received, no sound is generated from the remote control device 200 and the display device in step S26 The display shows that the user could not search the remote control device 200.

  Even in such a case, the user can search for the remote control device 200 using the mobile phone according to the embodiment of the present invention. Hereinafter, a search for the remote control device 200 by the mobile phone according to the embodiment of the present invention will be described.

  FIG. 3 shows a schematic configuration of the mobile phone according to the embodiment of the present invention. A cellular phone 300 according to an embodiment of the present invention includes an antenna 15, a transmission / reception unit 16, a storage unit 17, an operation unit 18, a display unit 19, an infrared transmission unit 20, and a microcomputer 21. .

  Based on an instruction from the microcomputer 21, the transmission / reception unit 16 performs a call with another telephone and data transmission / reception with various sites connected to the Internet via the antenna 15. The storage unit 17 stores various programs downloaded from various sites connected to the Internet. The operation unit 18 has various keys arranged on the outer surface of the mobile phone. The display unit 19 is composed of a liquid crystal panel or the like, and displays various images based on control signals from the microcomputer 21. The infrared transmitter 20 includes an infrared LED or the like, converts a command from the microcomputer 21 into an infrared signal, and outputs the infrared signal to the outside. The microcomputer 21 has a CPU, a ROM, and a RAM. The CPU executes various programs stored in the ROM while using the RAM as a work area or the like.

  With such a mobile phone 300, a program for adding a remote control device search function to the mobile phone 300 can be downloaded from the site of the manufacturer of the DVD device 100.

  First, when an operation for specifying an address of a site opened by the manufacturer of the DVD device 100 and an Internet connection operation are performed in the operation unit 18, the microcomputer 21 causes the transmission / reception unit 16 to connect to the specified site. The initial screen of the connected site is displayed on the display unit 19. Then, a program download screen is displayed on the display unit 19 by an operation on the operation unit 18.

  Here, when a download operation is performed in the operation unit 18, the microcomputer 21 acquires a program via the transmission / reception unit 16 and causes the storage unit 17 to store the acquired program. This completes the download.

  The remote control device search function is added to the mobile phone 300 by the program downloaded in this manner, and the remote control device 200 can be searched by the mobile phone 300.

  When the application list display operation is performed on the operation unit 18 after the download, a title list including the titles of the downloaded programs is displayed on the display unit 19, and the selection operation of the downloaded program titles is performed here. The microcomputer 21 starts executing the program stored in the storage unit 17.

  First, the microcomputer 21 displays a screen as shown in FIG. In this screen, a time similar to the set time display (“10 seconds”, “20 seconds”, “30 seconds”, “40 seconds”) corresponding to the slide position of the search mode setting switch of the remote control device 200 described above is selected as an item to be selected. Is displayed.

  Here, when an operation of selecting any one of the selection items is performed on the operation unit 18, the microcomputer 21 causes the display unit 19 to display a screen as illustrated in FIG. On this screen, selection items “execute search” and “end” are displayed. Here, when the selection operation of the selection item “search execution” is performed in the operation unit 18, the microcomputer 21 continuously outputs a specific command to the infrared transmission unit 20 for the set time selected above, and the infrared transmission unit 20. The transmitting unit 20 continuously transmits a specific command as an infrared signal to the outside for the selected set time. During the continuous transmission of the command, neither the “search execution” nor the “end” selection item can be selected, and when the command transmission is completed, the selection can be made again. When the remote control device 200 is in the search mode on state, if the remote control device 200 receives a specific command from the mobile phone 300 when the infrared signal can be received, the remote control device 200 generates sound.

  Note that, when the selection operation of the selection item “end” is performed on the operation unit 18, the microcomputer 21 ends the execution of the program.

  As described above, even when the remote control device 200 is located outside the searchable range of the DVD device 100 and cannot be searched, the user downloads the program to the mobile phone 300, starts the downloaded program on the mobile phone 300, and If the selection item “execute search” (FIG. 4B) is selected while carrying the telephone 300, the remote controller 200 generates a voice when receiving the command, and the user can search for the remote controller 200. .

  Further, if the user selects a set time corresponding to the slide position of the search mode setting switch of the remote control device 200 after starting the program on the screen (FIG. 4A), the infrared signal cannot be received during the set time. Since the command is continuously transmitted from the mobile phone 300 for the set time to the remote controller 200 that repeats the infrared signal receivable state and the infrared signal unreceivable state so as to enter the state, the remote controller 200 receives the command more reliably. Thus, the voice can be generated, and the user can find the remote control device 200 more reliably.
