Description

  The present invention relates to a remote control device capable of transmitting a remote control signal for device individual control to each of a plurality of remote control devices.

  Normally, a remote control device is provided as an accessory device dedicated to each remote control device having a remote control function, and is used for individual device control of the corresponding remote control device. Therefore, for example, when a plurality of remote control devices such as a television receiver (TV receiver) and a video tape recorder (VTR) are provided in the same room, there are as many dedicated remote control devices as there are devices. It will be. In such a situation, the user must use the device-specific remote control device corresponding to each remote control device to be controlled and perform individual device control, and the individual device operation due to the use of each dedicated remote control device is complicated. Met.

  Therefore, in order to solve the above-described problems of the individual device operation by the dedicated remote control device for individual device control, a multi-remote control device in which each of the plurality of remote control devices can be individually operated by one common remote device. Exists. This multi-remote control device has a configuration in which a dedicated remote control code corresponding to device individual control for each remote control device is stored in advance in the remote control device itself. With this configuration, when a user selects a remote control device to be controlled on the remote control device and performs the individual operation of the device, the device is used for individual control corresponding to the user's individual operation dedicated to the remote control device to be controlled. The remote control signal can be transmitted. If this multi-remote control device is used, even if the remote control device to be controlled is changed, the remote control device to be controlled can be selected by simply selecting the remote control device to be controlled on the multi-remote control device. On the other hand, a remote control signal for device individual control corresponding to the device individual operation can be transmitted.

  The operation of this multi-remote control device will be specifically described by taking as an example a case where a recorded image reproduced by a VTR as a remote control device is viewed on the screen of a TV receiver as the remote control device.

  In this case, using the multi-remote control device, the user selects the VTR of the video output device as the remote control device to be controlled, performs the playback operation of the recorded image as the device individual operation, and controls the remote control device to be controlled. A TV receiver is selected, and as an individual operation of the device, a switching operation for changing the input display mode to a video input corresponding to the VTR is performed. As described above, by using the multi-remote control device, it is possible to perform the VTR playback operation and the TV receiver input display mode switching operation with the same remote control device.

  However, even in the multi-remote control device having the above-described configuration, the TV can change the output image of each device from various video output devices such as a VTR, DVD (Digital Versatile Disc) player, set top box, etc. If you want to continue watching on the receiver's screen, whenever you change the output image of that device, select and change the remote control device to be controlled as needed, and change it to the desired video output device and TV receiver. On the other hand, a video output operation and an input display mode switching operation must be performed.

  Japanese Patent Laid-Open No. 2-283195 (Patent Document 1) discloses a system in which a TV receiver and a VTR can communicate with each other via an information transmission path, and the VTR starts a reproduction operation. The VTR sends a command to the TV receiver via this information transmission path to turn on the power of the TV receiver, and the image output from the VTR to the TV receiver is displayed on the screen of the TV receiver. A system for switching the input display mode so that it can be displayed is described.

  In JP-A-4-344354 (Patent Document 2), a TV receiver is connected to a remote control receiving unit that receives and determines a remote control signal transmitted to the VTR from a dedicated remote control device of the VTR, When this remote control receiving unit determines that a remote control signal for power supply [ON], playback, or channel selection is transmitted from the dedicated remote control device of the VTR to the VTR, the TV receiver is turned on [ON]. And a system for matching the input to an external input terminal or channel to which a VTR is connected. In addition, when it is determined that a power supply to the VTR is turned off or a remote control signal is transmitted from the dedicated remote control device of the VTR, the remote control receiving unit turns the TV receiver off. Or a system for matching the input of a TV receiver to the original input or channel.

Then, various data code including these manufacturer or a plurality of types of such mutually different models remote control device 2 ₁ to 2 _n of each device identification code I ₁ ~I _n or remote control code R ₁ to R _n are stored The data code memory 14 is constituted by a removable storage medium such as a ROM card, for example, and can be adapted to the latest remote control device 2 by exchanging the data code memory 14 itself if necessary. It is the composition.

  The remote control signal transmission device (control code transmission device) 15 is in an operation mode state M (2-x) based on the switching setting of the operation mode changeover switch 12 and corresponds to the operation of the device operation switch 13, which will be described later. The remote control signal data (control code) for the remote control device 2-x generated by is converted into a remote control signal and transmitted by radio.

  The control memory 16 stores a control processing program for the remote control device 20 described later, various control data calculated or stored during the execution, and the like.

  In this embodiment, the control memory 16 includes a switching state / operation mode correspondence storage unit 17, an input display mode setting state storage unit 18, and a viewing TV channel storage unit 19.

  The switching state-operation mode correspondence storage unit 17 includes a switching operation state of the operation mode changeover switch 12 of the operation unit 11, and remote control devices 2-1 and 2 in which the remote control device 20 generates remote control signal data for individual device control. -3, that is, the correspondence with the operation mode states M (2-1) to M (2-3) is stored.

The input display mode setting state storage unit 18 is a remote control device as a display device among the remote control devices 2-1 to 2-3, that is, in the case of FIG. 1, a display device and a video output device as the remote control device. stores the device identification code _{I 1} of TV receivers 2-1 also serves as the, stores the setting status of each input display mode m1~m3 the TV receiver 2-1. That is, the input display mode setting state storage unit 18 controls the remote control in which the video output is displayed and displayed on the display screen in each of the input display modes m1 to m3 of the TV receiver 2-1 as the display device of the remote control device. The corresponding states of the TV receiver 2-1, the DVD recorder 2-2, and the VTR 2-3 as the video output device of the device are stored.

  The viewing TV channel storage unit 19 selects the channel of the device operation switch 13 in the operation mode state M (2-1) in which the remote control device 1 individually controls the TV receiver 2-1 serving both as a display device and a video output device. The latest remote control signal data (control code) for channel selection generated by the remote controller 20 based on the operation of any one of the station number buttons or the data of the channel selection number buttons at that time is stored.

  The configuration of the control memory 16 can correspond to various configurations depending on, for example, the specific configuration of the operation mode switch 12 and the device operation switch 13 of the remote control device 1. As a specific example, the control memory 16 is not a switch in which the operation mode changeover switch 12 outputs an operation signal corresponding to each of the operation mode states M (2-1) to M (2-3). In the case of a single switch that only outputs the ON / OFF signal, the operation mode states M (2-1) to M (2) based on the ON / OFF signal of the operation mode changeover switch 12 are used. -3) is switched, and an operation mode state setting storage unit for storing the switched current operation mode state M (2-x) is also included. As described above, when the remote control device 1 is configured in advance as an attached remote control device of the TV receiver 2-1 as a display device of the remote control device, the switching state of the operation mode switch 12 and the display device are displayed. Since the correspondence with the states of the input display modes m1 to m3 of the TV receiver 2-1 can be matched in advance, the switching state-operation mode correspondence storage unit 17 or the input display mode setting state storage unit 18 Either of them can also function as the other, and the other can be omitted. In this way, the control memory 16 controls the remote control device 2 to be controlled corresponding to each of the operation modes M (2-1) to M (2-3) (each switching state of the operation mode changeover switch 12) of the remote control device 1. -1 to 2-3 and the correspondence relationship between the display modes m1 to m3 in the display device 2-1 which is also a remote control device for each of the remote control devices 2-1 to 2-3. If so, the specific configuration may be any.

  The remote control device 20 executes various functional processes of the remote control device 1 in cooperation with the units 14, 15, 16 based on the operation of the operation mode changeover switch 12 or the device operation switch 13 of the operation unit 11.

Specifically, the remote control device 20 refers to the switching state-operation mode correspondence storage unit 17 of the control memory 16 based on the operation of the device operation switch 13 of the operation unit 11, and the switching setting state of the operation mode change switch 12. To determine the operation mode state M (2-x). Then, the remote controller 20 is based on the data code including the device identification code I _x and the remote control code R _x corresponding to the determined operation mode state M (2-x) stored in the data code memory 14. Based on the operation of the device operation switch 13, remote control signal data (control code) for device individual control of the remote control device 2-x corresponding to the operation mode state M (2-x) is generated. After that, the remote control device 20 supplies the generated remote control signal data to the remote control signal transmission device 15, and the remote control signal transmission device 15 sends the remote control signal data of the remote control device 2-x corresponding to the operation mode state M (2-x). The remote control signal for device individual control is transmitted by radio.

  In this case, the remote controller 20 has the operation mode state M (2-x) corresponding to the TV receiver 2-1 as the display device, and the operation mode state M (2-x) When the generated remote control signal data (control code) is an instruction to change the reception channel to the TV receiver 2-1, the remote control signal data (control code) or the data of the channel selection number button at that time is further displayed. Then, it is updated and stored in the viewing TV channel storage unit 19.

In addition, when the operation mode changeover switch 12 of the operation unit 11 is operated by the user, the remote control device 20 acquires a new change setting state of the operation mode changeover switch 12. Then, the remote control device 20 refers to the switching state / operation mode correspondence storage unit 17 of the control memory 16 and determines a new operation mode state M (2-x) from the switching setting state of the operation mode switch 12. Remote controller 20, the input display mode of the device identification code I ₁ Toko of the TV receiver 2-1 of the TV receiver 2-1 as a display device stored in the input display mode setting state storage unit 18 M1 to With reference to the setting state of m3, the display mode mx corresponding to the remote control device 2-x in the new operation mode state M (2-x) is determined. Then, the remote control device 20 uses the data identification memory 14 based on the device identification code I ₁ of the TV receiver 2-1 acquired from the input display mode setting state storage unit 18 and the determined input display mode mx. based on the data code including a device identification code I _x and remote control code R _x may correspond to the TV receiver 2-1 stored in the input display mode of the TV receiver 2-1, a new operating mode state Remote control signal data (control code) for device individual control of the TV receiver 2-1 to be switched to the input display mode mx corresponding to M (2-x) is generated. Then, the remote control device 20 supplies the generated remote control signal data to the remote control signal transmission device 15 and wirelessly transmits and outputs a remote control signal for device individual control of the TV receiver 2-1 from the remote control signal transmission device 15.

  Accordingly, when the user operates the operation mode changeover switch 12 of the operation unit 11, the remote control device 20 changes the remote control device 2-1 as a display device to a new operation mode state M (2-x). Automatically switches to the corresponding input display mode mx.

  As a result, the video signal of the remote control device 2-x corresponding to the new operation mode state M (2-x) is displayed and output on the display screen of the remote control device 2-1 as the display device. .

  In connection with the control processing of the remote control device 20 when the user operates the operation mode change switch 12 of the operation unit 11 described above, a new operation mode state M (2-x) due to the change of the operation mode change switch 12 is displayed. In the case of the operation mode state M (2-1) of the TV receiver 2-1 as the device and the video output device, the remote control device 20 changes the input display mode of the TV receiver 2-1 to the TV receiver 7. A remote control signal for switching to the input display mode m1 for displaying the received broadcast video on the screen is wirelessly transmitted and output, and the following processing is also performed.

  In this case, when the remote control device 20 determines that the new operation mode state M (2-x) is the operation mode state M (2-1) of the TV receiver 2-1, the remote control controller 20 views the viewing TV of the control memory 16. With reference to the channel storage unit 19, the remote control signal data or channel based on the latest remote control signal data (control code) for channel selection stored or the data of the channel selection number button at that time A remote control signal for device individual control of the TV receiver 2-1 for receiving the TV broadcast corresponding to the channel selection number button is wirelessly transmitted and output.

  Therefore, when the new operation mode state M (2-x) by switching the operation mode selector switch 12 is the operation mode state M (2-1) of the TV receiver 2-1, the TV receiver 2-1 On this screen, the received broadcast video of the selected channel that was previously viewed is displayed on the screen.

  FIG. 2 is a flowchart showing a specific example of video viewing processing between the TV receiver and the video output device using the remote control device of the present embodiment.

First, at the beginning of viewing, the user constructs an AV system using the TV receiver 2-1 and the video output device 2-2 (FIG. 2, step S01). Specifically, the user connects the video output device 2-2 to the video input terminal 4 (4 ₁ ) of the TV receiver 2-1. Then, the user performs initial setting of the remote control device 1 in accordance with the system connection state between the TV receiver 2-1 and the video output device 2-2. This initial setting is a data initial setting of the switching state-operation mode correspondence storage unit 17 and the display mode setting state storage unit 18 of the control memory 16 described with reference to FIG. The data initial setting of the switching state-operation mode correspondence storage unit 17 and the display mode setting state storage unit 18 is, for example, predetermined menu buttons and channel selection number buttons included in the device operation switch 13 of the operation unit 11. It is performed by the user by a special operation or the like.

  After that, the user switches the operation mode switch 12 of the operation unit 11 to the operation mode state M (2-1) in which the remote control code (power-on code) of the TV receiver 2-1 is output. Switching (step S02).

  Then, the user presses the remote control power button included in the device operation switch 13 of the remote control device 1 to turn on the TV receiver 2-1 (step S03).

  In addition, when viewing a TV broadcast (step S04), the channel tuning number button included in the device operation switch 13 is operated to adjust the channel to a desired viewing program (step S05).

  On the other hand, when viewing the video content of the previously connected video output device 2-2 (step S06), the user switches the operation mode selector switch 12 of the operation unit 11 so that the video output device 2 is switched. Switching to the operation mode state M (2-2) in which the remote control code (power-on code) of -2 is output (step S07).

  In response to this switching, the remote control device 1 changes the input display mode of the TV receiver 2-1 to the input display mode m2 corresponding to the operation mode state M (2-2) for the video output device 2-2. A remote control signal for individual device control to be switched is output (step S08).

  Thereafter, the user looks at the video output on the screen of the TV receiver 2-1 (step S09), and whether there is an error in the initial setting of the remote control device 1 described in step S01 or the system connection. If there is an error, the initial setting of the remote control device 1 is reset according to the actual system connection, or if there is an error in the actual system connection, the device connection is redone (steps). S10).

  If there is no error in the initial setting or system connection of the remote control device 1, the user can view the video content by operating the video output device 2-2 with the remote control device 1 (step S11).

  Thereafter, when the user interrupts or ends the viewing of the video content on the video output device 2-2 and views the TV broadcast (step S12), the user performs the switching operation of the operation mode switch 12 of the operation unit 11. Then, the mode is switched to the operation mode state M (2-1) in which the remote control code (power-on code) of the TV receiver 2-1 is output (step S13).

  In response to this switching, the remote control device 1 changes the input display mode of the TV receiver 2-1 to the input display mode m1 corresponding to the operation mode state M (2-1) for the TV receiver 2-1. A remote control signal for individual device control to be switched is output (step S14). As a result, the broadcast video of the TV broadcast channel that the user has been viewing the latest is output on the screen of the TV receiver 2-1. Therefore, for example, when watching the progress of a TV broadcast that was being viewed before the viewing of video content, the TV receiver 2-1 can be viewed before the channel selection operation without performing the channel selection operation. The content status of the TV broadcast that was being performed can be confirmed.

  Further, when viewing the TV broadcast of another channel, the user can view a desired viewing program by operating the channel selection number button included in the device operation switch 13 of the operation unit 11 (step S15).

  In addition, when the user stops viewing the TV broadcast by the TV receiver 2-1 or the video content of the video output device 2-2, the user presses the remote control power button included in the device operation switch 13 of the remote control device 1. The power of 2-1 is turned off and the viewing ends (step S16).

  The remote controller of the present embodiment is as described above, but the embodiment of the remote controller of the present invention is not limited to this.

  For example, in the system example shown in FIG. 1, the case where there is one display device as a remote control device in the system has been described as an example, but the case where there are a plurality of display devices as remote control devices in the system is also supported. Is possible.

  In this case, the memory of the switching state-operation mode correspondence storage unit 17, the input display mode setting state storage unit 18, and the viewing TV channel storage unit 19 included in the control memory 16 described above can be associated with each display device. That's fine.

It is a block diagram which shows the structural example of the remote control apparatus of this Embodiment, and AV system using this remote control apparatus. It is the flowchart which showed the specific example of the video viewing process between TV receiver and video output apparatus using the remote control apparatus of this Embodiment.
