Description

  The present invention relates to an electronic device operable by a remote control device, an operation control method thereof, and a program. Specifically, the setting unit is set in advance to prohibit remote operation of the remote control device, and when receiving a control signal from the remote control device, whether or not the remote operation of the remote control device is set to prohibited. If it is determined that remote control of the remote control device is set to be prohibited, control is performed so as not to perform an operation corresponding to the remote control of the remote control device. When there are a plurality of electronic devices in which the code is used, the remote control device can be set to prohibit remote operation in advance for electronic devices other than the predetermined electronic device to be remotely operated. The present invention relates to an electronic device that can avoid simultaneous operation of the electronic devices.

  In recent years, most electronic devices such as television receivers, video players, CD players, and the like have come with remote control devices (remote control devices). In addition, the number of electronic device bodies has also been on an increasing trend compared to before. Furthermore, it is not uncommon to have multiple identical devices such as televisions and audios in one family.

  As described above, when a plurality of the same devices are held in the family, for example, as shown in FIG. 4, when a plurality of electronic devices of the same maker and the same category are held as A and B, the user can use the remote control device. If an attempt is made to control the electronic device main body A by operating the electronic device main body B, the electronic device main body B may also receive the code and perform an unintended operation.

  FIG. 5 is a diagram illustrating a configuration of a conventional electronic device. As shown in FIG. 5, the electronic device 1 includes a remote control device 1A and an electronic device main body 1B.

  The remote control device 1 </ b> A includes an operation unit 10, a microcomputer 20, and a light emitting element 30. The electronic device main body 1 </ b> B includes a light receiving element 40, a microcomputer 50, an operation unit 60, and a display device 70.

  FIG. 6 is a flowchart showing an operation example of the input unit 51 of the electronic apparatus main body 1B. When performing remote operation using the remote control device 1A, as shown in FIG. 6, the operation of the input unit 51 of the electronic device main body 1B first detects an input state, for example, presence or absence of input, in step S11. Next, in step S12, it is determined whether or not there is an input from the light receiving element 40. If it is determined that there is no input from the light receiving element 40, the operation is terminated. On the other hand, if it is determined that there is an input from the light receiving element 40, input data is measured in step S13. In step S14, it is determined whether the received code is a proper reception code based on the measurement result. If it is not a regular reception code, the operation is terminated. If it is determined that the received code is a legitimate received code, the determination unit 52 is activated in step S15. Then, the operation of the input unit 51 ends.

  FIG. 7 is a flowchart illustrating an operation example of the determination unit 52 of the electronic device main body 1B. When the remote control is performed, the operation of the determination unit 52 of the electronic device main body 1B is as follows. First, in step S21, input data is collated, as shown in FIG. Next, in step S22, it is determined whether or not the data input based on the collation result matches the data in the table in the decoding processing RMO. If it is determined that the data does not match the data in the table in the decoding processing RMO, the operation ends. On the other hand, if it is determined that the data matches the table data in the decoding processing RMO, processing data is created in step S23. Next, in step S24, the processing data created in step S23 is written into the processing data RAM. In step S25, the processing unit 55 is activated.

  In this way, the operation control process is performed based on the control signal from the remote control device 1A.

  Also, in recent years, in order to prevent the setting conditions of the electronic equipment from being changed by inadvertently touching the operation keys of the remote control device, an operation key reception prohibition switch has been provided in the remote control device, and this acceptance prohibition There has been proposed a remote control device in which a setting state cannot be changed even if another operation key is operated if a state of a device to be remotely controlled is set by switching a switch (see, for example, Patent Document 1). .

  In addition, a remote operation device that can control a plurality of controlled devices using one remote operation device has been proposed (see, for example, Patent Document 2). In this case, it is possible to automatically transmit data from the controlled device using the wireless function, and to provide an optimum interface for operation according to the state of the controlled device based on the data acquired from the controlled device. Moreover, permission / prohibition of remote operation can be set.

JP-A-60-223287 (pages 1, 2 and 2) JP 2002-199475 (pages 3, 4 and 1)

  As described above, in the conventional electronic device, when there are a plurality of electronic devices of the same manufacturer and the same category, when the user tries to control the electronic device main body A by operating the remote control device C, the electronic device main body B may also receive the code and perform an unintended operation.

  For example, if you have two kitchens with the same meter and you try to turn on TV A, you turn on TV B.

  I have two CD players from the same manufacturer, and when I try to play CD player A, CD player B also starts playing.

  I have two video players from the same manufacturer, and when I tried to set the recording mode of video player A, when I operated “3x → LP” cyclically, video player B became “LP → 3x” It will be set.

  In the case of Patent Document 1, if you have one electronic device, you can operate other operation keys by setting the status of the device to be remotely controlled by switching the operation key acceptance prohibition switch. However, if you have multiple electronic devices of the same manufacturer (that is, the same control code is used) as described above, all electronic devices can be switched by switching the acceptance prohibition switch. However, there is a problem that an electronic device to be operated cannot be operated.

  In the case of Patent Document 2, it is necessary to provide data transmission means in the controlled device, and it is necessary to set an ID for identifying the controlled device. Therefore, there is a drawback that the apparatus becomes complicated. In addition, it is possible to control a plurality of electronic devices of different categories, but if you have multiple electronic devices of the same meter (that is, the same control code is used) as described above, one of them The problem that other electronic devices were controlled when trying to control the device could not be solved.

  Therefore, according to the present invention, when there are a plurality of electronic devices in which the same control code is used, the remote control device can be set to permit or prohibit the remote control for each electronic device. It is an object of the present invention to provide an electronic device, a remote operation control method thereof, and a program capable of avoiding simultaneous operation.

Or setting means for setting permission, determination means for determining whether or not remote operation of the remote control device is set to be prohibited by the setting means, and remote control of the remote control device is set to be prohibited by this determination means. When it is determined, the control unit includes a control unit that performs control so as not to perform an operation corresponding to the remote operation of the remote control device.

  For example, the setting means sets prohibition or permission of remote operation by the remote control device based on an input of an operation key or a changeover switch provided on the main body.

  The remote operation control method according to the present invention includes: setting means for setting prohibition or permission of remote operation by the remote control device; determination means for determining whether remote operation is set to prohibit; and remote operation is set to prohibit In such a case, there is a plurality of electronic devices that use the same control code in a range where wireless communication is possible in an electronic device that includes a control unit that performs control so as not to perform an operation corresponding to a remote operation of the remote control device. A remote control method, a setting step for prohibiting remote operation of the remote control device in advance for electronic devices other than the predetermined electronic device to be remotely controlled, and a control signal from the remote control device. When receiving, a determination step for determining whether or not remote operation of the remote control device is set to be prohibited in the setting step, and remote operation of the remote control device is prohibited in the determination step. If it is determined to have been set to one in which a control step of controlling so as not to perform an operation corresponding to the remote operation of the remote control device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of an electronic device 100 as an embodiment. Here, the electronic device 100 is, for example, a CD player.

  As shown in FIG. 1, the electronic device 100 includes a remote control device (remote control device) 101 and an electronic device main body 102 as a main body.

  The remote control device 101 includes an operation unit 10, a microcomputer 20, and a light emitting element 30. The electronic device main body 102 includes a light receiving element 40, a microcomputer 50, an operation unit 60, and a display device 70.

  The operation unit 10 includes a plurality of operation keys provided on the remote control device 101. The remote control device 101 includes, for example, a power key for power on / off, a numeric input operation key, a cursor operation up (UP) key, a down (DOWN) key, and an enter key for determining input. Yes. An operation command can be input from these operation keys. An operation command input from the operation key is supplied to the microcomputer 20.

  The microcomputer 20 includes an input unit 21, a determination unit 22, a decode conversion ROM 23, an output data RAM 24, a processing unit 25, and a transmission unit 26. The microcomputer 20 controls the overall operation of the remote control device 101 according to control program information stored in advance.

  The light emitting element 30 is driven by a signal from the transmitter 26 and emits light in a pattern corresponding to the input signal to generate an optical signal. The optical signal generated from the light emitting element 30 is transmitted in the air. For example, it is transmitted to the light receiving element 40 of the electronic device main body 102.

  In the remote control device 101, when the input unit 21 detects the operation key press of the operation unit 10, the input unit 21 converts the received operation key press data into determination data and supplies the data to the determination unit 22. The determination unit 22 collates the input data with the decode conversion ROM 23 to determine the command data to be output, and writes it in the output data RAM 24.

  Next, the processing unit 25 reads the data written in the output data RAM according to a certain transmittable timing, and activates the transmission unit 26. The activated transmission unit 26 transmits this data via the light emitting element 30 according to a predetermined protocol.

  The light receiving element 40 receives the optical signal transmitted from the light emitting element 30 and outputs it as an electrical signal.

  The microcomputer 50 includes an input unit 51, a determination unit 52, a decode conversion ROM 53, a processing data RAM 54, a processing unit 55, a display unit 56, and a control unit 57. The microcomputer 50 controls the overall operation of the electronic device main body 102 according to control program information stored in advance.

  The microcomputer 50 includes a setting unit that sets prohibition or permission of remote operation by the remote control device 101 according to an input from the operation unit 60, and whether or not the remote operation of the remote control device 101 is set to be prohibited by the setting unit. A state determination unit that determines whether or not the remote control device 101 is controlled to be prohibited from performing an operation corresponding to the remote operation of the remote control device 101 when it is determined by the state determination unit that remote control of the remote control device 101 is prohibited. It also functions as a control means. For example, when setting prohibition or permission of remote operation by the remote control device 101, when the user manually inputs a command from the operation unit 60, the setting means performs the remote operation by the remote control device 101 based on the input from the operation key. Has been set to prohibit or permit.

  The operation unit 60 includes a plurality of operation keys provided on the electronic device main body 102. The electronic device main body 102 includes, for example, a power key for power on / off (ON / OFF), an operation key for numeric input, an up (UP) key for cursor operation, a down (DOWN) key, and an ENTER key for determining input. Etc. are arranged. An operation command can be input from these operation keys. An operation command input from the operation key is supplied to the microcomputer 50. Based on the input of these operation keys, prohibition or permission of remote operation by the remote control device 101 can be set. A dedicated key for setting prohibition or permission of remote operation by the remote control device 101 may be provided.

  The display device 70 displays an image based on the display data, and for example, a liquid crystal panel is used. When the prohibition of remote operation of the remote control device 101 is set by the setting means, the display device 70 displays that fact.

  In the electronic device main body 102, the input unit 51 inputs transmission data from the remote control device 101 through the light receiving element 40. The input data is converted into determination data and supplied to the determination unit 52. The determination unit 52 confirms by comparing the decode conversion ROM 53 that the determination data is data registered as a device. As a result of confirmation, if the data is normal, the data is written into the processing data RAM 54. For example, the processing unit 55 activates the display unit 56 and outputs display data to the display device 70 in accordance with the contents of the processing data RAM 54.

  The electronic device main body 102 may be provided with a changeover switch for setting prohibition or permission of remote operation by the remote control device 101. In this case, it is possible to set prohibition or permission of remote operation by the remote control device 101 based on the input of the changeover switch.

  Next, the operation of the electronic device 100 illustrated in FIG. 1 will be described with reference to FIGS. 2 and 3. FIG. 2 is a flowchart showing an operation example when setting prohibition or permission of remote operation. FIG. 3 is a flowchart illustrating an operation example of the determination unit 52 of the electronic device 100.

  In the electronic device 100, when setting the prohibition or permission of the remote operation by the remote control device 101, the operation of the control unit 57 starts from the operation unit 60 of the electronic device main body 102 in step S31 as shown in FIG. It is determined whether or not there is a key input. If there is a key input, the input data is collated in step S32.

  Next, in step S33, it is determined whether or not the instruction is a decoding prohibition (remote operation prohibition) command. If it is a decode prohibition instruction, the prohibition instruction data is transmitted to the determination unit 52 in step S34. And it progresses to step S37 and the determination part 52 is started by step S37. On the other hand, if it is determined in step S33 that the instruction is not a decode prohibition instruction, the process proceeds to step S35.

  In step S35, it is determined whether or not it is a decode permission (remote operation permission) command. If it is determined that the instruction is a decode permission instruction, the permission instruction data is transmitted to the determination unit 52 in step S36. In step S37, the determination unit 52 is activated. If it is determined in step S35 that the instruction is not a decode permission instruction, a normal key input signal is processed in step S38, and the operation is terminated.

  When a control signal from the remote control device 101 is input to the input unit 51 via the light receiving element 40, the input unit 51 first enters an input state from the light receiving element 40, for example, an input state as shown in FIG. Detects presence or absence. When there is an input, the data is measured. Next, based on the measurement result, it is determined whether or not the data is a regular reception code. If the data is a regular reception code, the determination unit 52 is activated.

  As shown in FIG. 3, when the determination unit 52 is activated, the determination unit 52 first determines whether or not decoding is prohibited in step S41. If it is determined that decoding is prohibited, the operation is terminated. On the other hand, if it is determined that decoding is not prohibited, input data is collated in step S42. In step S43, it is determined whether or not the input data matches the data in the table in the decoding processing ROM. If they do not match, the operation ends. On the other hand, if it is determined that the input data matches the data in the table in the decoding ROM, processing data is created in step S44. In step S45, the created processing data is written into the processing data RAM 54. Next, in step S46, the processing unit 55 is activated.

  As described above, in the case where a plurality of electronic devices of the same manufacturer and the same type as shown in FIG. 4 are possessed, the remote control device C is used to remotely control the electronic device main body A and the electronic device main body B. At this time, the electronic device main body A or the electronic device main body B can be set in advance to prohibit remote operation by the remote control device C.

  For example, when it is desired to operate the electronic device main body A with the remote control device C, the electronic device main body B is set in advance to prohibit remote operation of the remote control device. When the power key of the remote control device C is pressed when operating the electronic device main body A, the electronic device main body A receives the remote operation of the remote control device C and performs an operation according to the Power key. At this time, the electronic device main body B is set so as to prohibit the remote operation of the remote control device, and therefore does not operate even when the operation signal of the remote control device C is received.

  Similarly, when it is desired to operate the electronic device main body B with the remote control device C, the electronic device main body A is set in advance to prohibit remote operation of the remote control device. When the power key of the remote control device C is pressed when operating the electronic device main body B, the electronic device main body B receives the remote operation of the remote control device C and performs an operation according to the Power key. At this time, the electronic device main body A is set so as to prohibit the remote operation of the remote control device, and therefore does not operate even when the operation signal of the remote control device C is received.

  As described above, in the present embodiment, the electronic apparatus main body 102 has setting means for setting prohibition or permission of remote operation by the remote control device 101 and prohibits remote operation of the remote control device 101 by the setting means. A determination unit that determines whether or not the remote control device 101 has been set, and when the determination unit determines that the remote operation of the remote control device 101 is prohibited, an operation corresponding to the remote operation of the remote control device 101 is not performed. When there are a plurality of electronic devices 100 that use the same control code in a range where wireless communication is possible, the electronic device 100 other than the predetermined electronic device 100 to be remotely operated is provided. The remote control device 101 is set in advance to prohibit remote operation, and when a control signal is received from the remote control device 101, the remote control device 101 It is determined whether or not the remote operation is set to be prohibited, and when it is determined that the remote operation of the remote control device 101 is set to be prohibited, control is performed so that the operation corresponding to the remote operation of the remote control device 101 is not performed. .

  Accordingly, when there are a plurality of electronic devices 100 that use the same control code in a range where wireless communication is possible, it is possible to set prohibition or permission of remote operation by the remote control device 101 for each electronic device 100. It is possible to avoid a plurality of electronic devices from operating simultaneously by remote operation. In addition, since the prohibition / permission control of remote operation of the electronic device can be realized by software, the cost of the electronic device can be suppressed.

  In addition, since prohibition or permission of remote operation by the remote control device 101 can be set by the user's intention, an environment can be constructed in accordance with the personal use situation, and convenience can be improved.

  Moreover, when purchasing an electronic device, it becomes possible to select an electronic device of the same manufacturer without being restricted by the restrictions of the remote control device (remote control).

  In the future, it may be possible to reduce the number of remote control devices in each home by integrating multiple remote control devices (remote control). It is possible to prevent malfunctions and malfunctions that occur when operating with one remote control device.

  In addition, since prohibition and permission of remote operation by the remote control device can be freely set, it becomes possible for the developer to perform design development in an environment in which malfunction of the electronic device does not occur in the development process of the electronic device.

  In the above-described embodiment, the case where electronic device 100 is a CD player has been described. However, the present invention is not limited to this. The present invention can also be applied to electronic devices other than CD players, such as television receivers and video players. When the electronic apparatus 100 is a television receiver, the display device 70 may use a cathode ray tube or an EL display (Electroluminescence display) in addition to the liquid crystal panel.

  Further, in the above-described embodiment, processing is added by software to make a decode prohibition permission determination. However, a method of prohibiting input of the receiving element 40 by hardware is also conceivable. In this case, a changeover switch is added between the receiving element 40 and the microcomputer 50, and control of this changeover switch is processed by the control unit 57. In this case, the cost increases, but the software processing load can be reduced.

  When there are a plurality of electronic devices in which the same control code is used in a range where wireless communication is possible, only a specific electronic device can be applied for remote operation.
