Description

  The present invention relates to a remote controller (hereinafter referred to as a remote controller) for operating a video display device, and the video display device.

  The remote control is a device capable of storing and transmitting a code for controlling an electronic device, and is also attached to a video display device such as a TV monitor or a PC monitor for displaying an image from a personal computer (PC). Yes.

  Regarding a remote control setting method, for example, in Patent Document 1, an electronic device transmits remote control setting data (remote control information) from an information storage medium provided in the electronic device main body to the remote control, and the remote control is transmitted from the electronic device main body. A technique for performing code setting based on the setting data has been disclosed. Here, an IC (Integrated Circuit) tag is used as an information storage medium.

  By the way, with the recent expansion of the market of thin television devices, the demand for large-screen television devices for installation in living rooms is increasing. In the past, there were many front-projection type projection TVs when talking about ultra-large screen TVs, but plasma TVs and LCD TVs that have exceeded the 50-inch type have been commercialized today. It has been commercialized. In addition, regarding the large-screen PC monitor, the demand from corporate users is increasing.

  When the video display device becomes larger in this way, the screen is divided and shared by a plurality of users (viewers) at the same time, or used by a plurality of users with different video settings for each individual. Will increase. In other words, as the screen size of the video display device becomes larger, the need for a plurality of users to individually operate one video display device increases. And in such a scene, it is not good that each remote control operation affects other remote control operations.

Patent Document 2 discloses a technique for sharing a screen with a plurality of remote controllers using a multi-screen display device in which a specified ID (IDentification) is set on the remote controller side. With this technology, a plurality of users can individually operate one video display device without affecting each other remote control operation, that is, the corresponding ID screen (window) is operated by each remote control. It is possible to do.

  Hereinafter, the video display device according to the present invention will be described by taking a television device as an example, but the present invention can be similarly applied to other video display devices such as a display such as a PC monitor connected to a PC to display data. . As the video display device according to the present invention, a liquid crystal display device is taken as an example. In addition, various displays such as a PDP (Plasma Display Panel), an organic EL (Electro Luminescence), an LED (Light Emitting Diode) display device, etc. The system can be applied.

  FIG. 1 is a diagram illustrating a configuration example of a set of a television device and a remote controller according to an embodiment of the present invention, in which 1 is a television device, and 3 is a remote controller for remotely operating the television device 1. Although there are a plurality of remote controllers 3 capable of operating one television apparatus 1, the split screen area allocation process (registration process) according to the present invention is executed for each remote controller 3, and therefore in FIG. Only one remote control 3 is shown. It is preferable that the number of remote controllers 3 for one television apparatus 1 is the maximum number of divisions (for example, four in the television apparatus 1 that can be divided into two and four) that are targets of registration processing of the present invention. Moreover, in the television apparatus 1 of FIG. 1, the control line is shown with the dotted line.

  The remote controller 3 illustrated in FIG. 1 includes a CPU (Central Processing Unit) 30 that controls the entire remote controller 3, a key group 31 including a plurality of operation keys, and an EEPROM (Electrically Erasable and Programmable Read Only Memory) that stores a code group to be transmitted. ) And the like, the key code transmitting unit 34 that transmits an operation key code corresponding to each key of the key group 31 as an operation signal (remote control signal), and the TV apparatus 1 An ID receiving unit 32 that receives the ID wirelessly is provided. The CPU 30 may be implemented as a microcomputer.

  On the other hand, a television device 1 illustrated in FIG. 1 includes a control unit 10 that controls the entire television device 1, a tuner unit 11 that receives and demodulates and decodes a video / audio signal using broadcast waves, an externally connected recorder, and an STB (Set Video input / output signal from the top box), the video input IC 12 for performing various video processes on the video signal input from the tuner 11 or the external input unit 12, and the audio signal. An audio processing IC 14 that performs audio processing is provided.

  The control unit 10 stores a control program in, for example, a built-in ROM, and the built-in CPU reads the stored control program onto the built-in RAM and temporarily stores the data being processed in the RAM. What is necessary is just to comprise with the microcomputer to execute. The operation signal received by the key code receiving unit 18 is input to the control unit 10, and control indicated by the operation signal is performed by the control program. The operation signal may be decoded by the control unit 10 or the key code receiving unit.

  Furthermore, the television apparatus 1 receives a display device driver 15 that drives the display 17, a backlight unit 16 that illuminates the display 17 from the back, a non-self-luminous display 17 such as a liquid crystal, and a code that is an operation signal from the remote control 3. A key code receiving unit 18, a speaker 19 that emits sound indicated by a sound signal output from the sound processing IC 14, and an IC tag 20 that wirelessly transmits (transmits) an ID.

  The display device driver 15 drives the display 17 so that the video indicated by the video signal output from the video processing IC 13 is displayed on the display device (here, the liquid crystal display 17). Further, the IC tag 20 is an active RFID (Radio Frequency IDentification) type tag having a memory 21 storing an ID as target screen information, which will be described later, and an ID transmitting unit 22 that wirelessly transmits (transmits) the ID without contact. It is. The memory 21 stores, for example, the number of divided screen areas, that is, the ID of the number of screens at the time of division.

  The television device 1 according to the present invention can be operated from a plurality of remote controllers 3 and can at least perform split screen display. For example, the control unit 10 controls the source input to the video processing IC 13 and sets the display area (divided screen area) of the video signal from each source to display the video in accordance with the area. This can be realized by controlling the conversion.

  The set of the television device 1 and the remote controller 3 according to the present invention includes an operation target setting unit that sets an operation target of a divided screen for each remote controller 3 as described below. As the operation target setting means, a target screen information transmitting unit described later is provided on the television device 1 side, and a target screen information receiving unit, storage unit, and transmission code registration unit described later are provided on the remote control 3 side.

  First, a target screen information transmission unit provided on the television device 1 side transmits target screen information for specifying a divided display area to be operated by the remote control 3 among the displayable divided screen areas to the remote control 3. To do. This target screen information transmission unit is exemplified by the IC tag 20.

  The target screen information receiving unit on the remote control 3 side receives target screen information indicating an area specified as an operation target of the remote control 3 among the divided screen areas that can be displayed on the television device 1. The target screen information is exemplified by an ID, and the target screen information receiving unit is exemplified by an ID receiving unit 32 that is an IC tag reader that reads an ID transmitted from the IC tag 20.

  The storage unit on the remote control 3 side stores the target screen information and the transmission code in association with each of the divided screen areas that can be displayed on the television device 1 as a set. This storage unit is exemplified by the memory 33. The memory 33 preferably stores a transmission code corresponding to each target screen information and also stores an operation key code corresponding to a normal key.

  Here, the transmission code is a code that is transmitted from the remote controller 3 to the television apparatus 1 in order to designate an operation target area at the time of divided display. The target screen information stored here is for all the divided screen information that can be received from the television apparatus 1 by the target screen information receiving unit, and can be said to be a target screen information group. Therefore, there are as many sets to be stored as the number of divided screen areas. Further, when the television apparatus 1 has a function of dividing and displaying by a plurality of types of screen division methods such as two divisions, three divisions, and four divisions, a plurality of sets may be stored for each of the screen division methods. For example, if the television device 1 can display a screen in two and four divisions in addition to full screen display, two sets for two divisions and four sets for four divisions may be stored.

  The transmission code registration unit on the remote control 3 side reads the transmission code corresponding to the target screen information from the storage unit with respect to the target screen information actually received by the target screen information reception unit, and performs operations for split display in the storage unit Register as a transmission code indicating the target. This transmission code registration unit is exemplified by the CPU 30.

  In this transmission code registration, the operation key code may be reset so that the transmission code is included in the operation key code corresponding to each key of the key group 31. That is, a setting may be made to associate an operation key code with a transmission code attached to each key. Alternatively, when the key code transmission unit 34 transmits the operation key code corresponding to the key, the transmission code may be attached and transmitted. In order to explain the transmission code and the operation key code separately, the latter case will be adopted and explained below.

  As described above, the remote controller 3 according to the present invention includes a plurality of sets stored in the storage unit on the remote controller 3 side, and the divided screen area related to the target screen information actually received by the target screen information receiving unit is assigned to the remote controller 3. It will be selected and registered as an operation target.

  In order to enable the remote control 3 to operate the divided screen to be operated and registered as described above, an operation unit (also referred to as an operation key input unit) and a code transmission unit, which will be described later, are provided on the remote control 3 side. A storage unit, a code receiving unit, and a control unit, which will be described later, are provided on the side.

  First, the operation unit on the remote controller 3 side has a plurality of operation keys for performing operations (key operations) on the television device 1. This operation unit is exemplified by a key group 31. These operation keys may be operation keys that are normally provided on the remote control attached to the television apparatus 1. For example, the up / down movement key, the left / right movement key, the enter key, the cancel key, the input switching key, the volume adjustment key, the selection key, and the like. A station key, a menu screen display key, etc. may be provided.

  The code transmission unit on the remote control 3 side reads the transmission code registered by the transmission code registration unit from the storage unit when the key is operated by the operation unit, and operates keys corresponding to the keys operated by the operation unit Send with code. This code transmission unit is exemplified by the key code transmission unit 34. As described above, the operation key code may be stored in the memory 33 corresponding to the key and read at the time of transmission.

  The code receiving unit on the television device 1 side receives the operation key code and the transmission code transmitted from the remote controller 3 as operation signals. This code receiving unit is exemplified by the key code receiving unit 18. Basically, the operation key code and the transmission code are received as a set of operation signals (remote control signals).

  For example, in Japan, the key code transmission unit 34 on the remote control 3 side and the key code reception unit 18 on the television device 1 side use the format of the Japan Electrical Appliances Association format or each manufacturer's unique infrared communication system to transmit infrared data. What is necessary is just to comprise as an optical part and an infrared rays light-receiving part, respectively. In addition to the infrared communication method, other wireless communication methods such as a wireless PAN (Personal Area Network) such as Bluetooth (registered trademark), UWB (Ultra Wide Band), and Zigbee may be adopted.

  The storage unit on the television device 1 side associates specification information for designating a divided screen area with a transmission code for designating an operation target area for each of the displayable divided screen areas. Memorize the set. As the storage unit, for example, a memory such as a ROM may be provided in the control unit 10 (or the key code receiving unit 18). The transmission code here is a transmission code that has a possibility of being transmitted from the remote controller 3. In addition, there are as many sets as the number of divided screen areas to be stored, but when the television apparatus 1 has a function of dividing and displaying by a plurality of types of screen dividing methods such as two-division, three-division, and four-division. A plurality of sets are stored for each screen division method.

  The control unit on the television device 1 side reads the designation information corresponding to the transmission code received by the code receiving unit from the storage unit, and becomes the operation target of the remote controller 3 by the operation key code received together with the transmission code by the code receiving unit. A divided screen area (that is, a divided screen area to be operated by the received operation key code) is determined (designated). In this way, the divided screen area to be operated can be determined from the transmission code. Then, the control unit controls to execute the processing of the operation content indicated by the operation key code for the display of the designated divided screen area. This control part can be illustrated by the control part 10 which consists of CPU etc., or the key code receiving part 18 control part 10. FIG.

  In addition, when the transmission code corresponding to the divided screen area is transmitted when the full screen is displayed instead of the divided display, the television apparatus 1 ignores the transmission code included in the operation signal from the remote controller 3, for example. By performing the operation, it is possible to operate the currently displayed screen (full screen). However, for operation key codes that correspond to operation keys that display a split screen by switching the screen division method during full screen display, at least the input source and settings during full screen display correspond to the transmission code. It is desirable to reflect the position in the divided screen area.

  Note that the control unit of the television apparatus 1 only needs to read the corresponding designation information from the storage unit when the transmission code is recognized from the operation signal received by the code receiving unit and the transmission code is included. Therefore, when an operation key code without a transmission code is received, such control may be controlled as an operation on the entire screen. For example, it corresponds to a case where an operation key code is received from the remote controller 3 in which the divided screen area to be operated is not set or an operation key code is received from a remote controller not corresponding to the present invention.

  With the configuration according to the present invention, the set according to the present invention can set the divided screen area to be operated as the operation target by dividing the display on the television device 1 for each of the plurality of remote controllers 3 by a simple method. Furthermore, according to this set, the setting (registration) on the remote controller 3 side can be rewritten (that is, the divided screen area is switched), and another divided screen area can be set as the operation target. As a result of such setting, it is possible to operate the split screen of the large TV with a different transmission code assigned individually, and to view the TV apparatus 1 with user settings such as different video settings for each user. It becomes. Further, since the remote controller 3 corresponds to the individual user, and the ID can be said to be an ID for identifying the individual, this set can be used to set the operation key together with the setting of the ID for identifying the individual. I can say that.

  A more preferred embodiment of the set having the above-described configuration will be described with reference to FIGS. 1 and 2 to 4. 2 is a front view showing an example of split screen display of the television apparatus of FIG. 1, and FIG. 3 is a registration process of a split screen area to be operated between the television apparatus illustrated in FIGS. 1 and 2 and a remote controller. FIG. 4 is a diagram for explaining the remote control operation after the registration process of FIG.

  In the embodiment described here, the key group 31 in the remote controller 3 described above has a transmission request operation key for requesting transmission of target screen information received by the ID receiving unit 32, that is, the remote controller 3 has a transmission request for target screen information. A transmission request operation unit for performing This transmission request operation key is a key for making an ID transmission request and registering and setting an ID in the remote controller 3 itself, and can also be said to be an ID setting key.

  Then, the key code transmission unit 34 transmits a request from the transmission request operation unit, that is, an operation key code corresponding to the transmission request operation key. The key code transmission unit 34 may transmit at least the corresponding operation key code in response to the input of the transmission request operation key, and may not transmit the transmission code. Even when a certain transmission code is set as a default), there is no problem because the television apparatus 1 can recognize that a transmission request is instructed from the operation key code.

  On the television device 1 side, when the key code receiving unit 18 receives an operation key code corresponding to a transmission request for target screen information, the user is allowed to select a target divided screen region. The operation key code received here may be, for example, an operation key code for displaying a menu image.

  In order to enable such user selection, the control unit 10 first receives target screen information to be transmitted by the ID transmission unit 22 of the IC tag 20 when receiving the operation key code corresponding to the transmission request for the target screen information. Control is performed so that a menu image for selecting (ID here) is displayed on the display 17 by OSD (On Screen Display). This menu image can be said to be a divided screen region selection OSD image for selecting target screen information.

  The OSD image display process itself may be executed by an existing technique. For example, an OSD processing unit in which an OSD image for selecting a divided screen area is stored in an internal ROM or the like is connected to the control unit 10, and a video from the video processing IC 13 and an OSD image from the OSD processing unit are superimposed. A combining unit may be provided between the video processing IC 13 and the display device driver 15. Then, the control unit 10 instructs the OSD processing unit to display the OSD image for selecting the divided screen area, and the composition unit superimposes it on the video from the video processing IC 13 and outputs it to the display device driver 15. That's fine. Alternatively, in the configuration of FIG. 1, the OSD image is transferred to the video processing IC 13 together with the instruction so that the divided screen area selection OSD image stored in the built-in ROM or the like in the configuration of FIG. The video processing IC 13 may superimpose the OSD image on a video sourced from the tuner unit 11 or the external input unit 12 and output it to the display device driver 15.

  Further, the above-described transmission request operation key may be substituted by, for example, displaying a menu including a transmission request item on the display 17 after the menu screen display key is pressed and allowing the user to select the transmission request item. That is, the transmission request operation key may be a plurality of keys for performing a transmission request as a series of key operations, such as a menu screen display key, a selection key, and a determination key.

  When the control unit 10 receives the operation key code corresponding to the request for determining the selection by the key code receiving unit 18 while the OSD image for selecting the divided screen area is being displayed (that is, after the operation of the transmission request operation key), the control unit 10 The tag 20 is controlled to execute the next process. The ID transmission unit 22 of the IC tag 20 reads the target screen information (ID) selected and determined from the memory 21 under the control of the control unit 10 and wirelessly transmits it.

  On the remote control 3 side, the transmission from the ID transmission unit 22 is received by the ID reception unit 32, and the CPU 30 reads the transmission code corresponding to the received target screen information (ID) from the memory 33 and displays it at the time of divided display. The transmission code representing the operation target is registered in the memory 33. The transmission code registered here is used to interpret that the divided screen area indicated by the target screen information is an operation target in the television apparatus 1.

  With reference to FIG. 2 to FIG. 4, a specific example of registration processing will be described assuming that the television device 1 can display a screen in two divisions as shown in FIG. 2. Here, the left side is the screen I (17a), the right side is the screen II (17b), and the IC tag 20 is preferably built in any position of the television device 1.

  First, the user A presses the transmission request operation key with the remote controller A (3a). At that time, as shown in FIG. 3A, the remote controller A (3a) transmits an operation signal including at least an operation key code for this key from the key code transmission unit 34, and the TV apparatus 1 uses the key code reception unit 18 to transmit this operation signal. Receives an operation signal. Then, the control unit 10 performs control to display the divided screen region selection OSD image (ID setting menu image) on the display 17. As shown in FIG. 3A, for example, an OSD image for selecting a divided screen area used for setting when displaying a two-divided screen as shown in FIG. 2 can be selected together with a description indicating that it is a remote control ID selection screen. What is necessary is just to set it as the image on which ID (here ID1 and ID2) was displayed.

  Subsequently, when the user performs an operation of selecting an ID (in this case, ID1) to be set with the cursor up / down key on the remote control A (3a) while displaying the divided screen area selection OSD image, the key code transmission unit 34 is selected. A corresponding operation signal is issued from. In the television apparatus 1 that has received the operation signal by the key code receiving unit 18, the control unit 10 performs control to reflect the selection on the OSD display like the image 15a. Further, when the user confirms the selection by pressing the enter key on the remote controller A (3a), the key code transmission unit 34 transmits a corresponding operation signal.

  In the television apparatus 1, the key code receiving unit 18 receives the operation signal, the control unit 10 performs control to turn off the OSD display, and the ID transmission unit 22 of the IC tag 20 determines the ID 1 (for example, a determination request). ID1 is recognized as the ID selected at the time of reception) from the memory 21 and wirelessly transmitted. Here, the power supply of the IC tag 20 is preferably performed by the control unit 10 using a power supply control unit (not shown) when any ID is selected because power saving can be achieved.

  In the remote control A (3a), the ID receiving unit 32 receives the ID1 signal, and the CPU 30 reads out the transmission code corresponding to the received ID1 from the memory 33 and uses it as a transmission code representing the operation target at the time of split display. Register in the memory 33. The ID reception unit 32 can receive the ID by placing the remote controller A (3a) within the radio wave reachable range of the IC tag 20 when the transmission request operation key is pressed.

  Similarly, the user B presses the transmission request operation key on the remote controller B (3b), and selects ID2 as shown in the image 15b in FIG. 3B in the displayed OSD image, whereby the remote controller B (3b ) Can register a transmission code corresponding to ID2.

  Here, as a matter of course, the user A may also perform the setting for the user B. Further, even if the selection is confirmed when setting the ID of the remote controller A (3a), the image 15a in FIG. 3A may not be turned off unless cancellation is selected / decided. By such control, the ID setting of the remote control B (3b) following the remote control A (3a) is executed only by the ID selection / determination operation without pressing the transmission request operation key with the remote control B (3b). be able to.

  As described above, the actual operation when ID1 and ID2 are set for the remote controls A (3a) and B (3b), that is, when the screen I (17a) and the screen II (17b) are set as operation targets will be described. To do. In the television apparatus 1, the control unit 10 recognizes the transmission code when displaying the divided screen, reads the designation information corresponding to the transmission code from the internal memory, determines the divided screen area to be operated, and receives the operation received together with the transmission code. The entire television apparatus 1 is controlled to execute the operation content indicated by the key code.

  Therefore, as shown in FIG. 4A, since the remote control A (3a) includes a transmission code corresponding to ID1 in the operation signal, the TV apparatus 1 operates with the screen I (17a) as an operation target. II (17b) does not operate and does not operate. Similarly, as shown in FIG. 4B, since the remote control B (3b) includes a transmission code corresponding to ID2 in the operation signal, the TV apparatus 1 operates with the screen II (17b) as an operation target. The screen I (17a) is not operated and does not operate.

  Of course, ID1 may be set by both remote controllers A (3a) and B (3b), or ID2 may be set. In this case, for example, in the former setting of ID1, the screen I (17a) operates as an operation target on both the remote controls A (3a) and B (3b), but the screen II (17b) does not become an operation target. It will not work.

  Further, after such a setting, if it is desired to operate a screen other than the corresponding ID screen, it can be handled by acquiring the ID of the screen to be operated and performing the key setting again. For example, even when ID1 is set by the remote controller A (3a), it can be reset to ID2 by the same procedure.

  In addition, here, the television apparatus 1 is originally described as being simply divided into two and the number of remote controllers 3 is two. However, when there are three or more remote controllers, the third and subsequent remote controllers are similarly described. What is necessary is just to perform a registration process with respect to a remote control. In this case, when there are three or more divided screens, each divided screen area can be set in each remote controller while avoiding duplication.

  Further, for example, when split display can be performed in two splits and three splits, and the registration processing of the present invention is applied to both screen splitting methods, the setting for splitting in the OSD image for selecting split screen areas is set. An item and a setting item for three divisions are provided, and a selection item for selecting which divided screen region should be displayed below them. At this time, if it is stored as designation information in the internal memory of the control unit 10 for each ID, which screen of 2 divisions corresponds and which screen of 3 divisions corresponds, the operation target Can be determined. Alternatively, each of the two-divided areas and each of the three-divided areas may be associated with each other in advance, and when the registration process for one screen division method is completed, the other registration process is automatically completed.

  In addition, the selection item of the divided screen area is also exemplified as the ID selection item. However, the left screen item and the right screen item are displayed for two screens, and the upper left screen, lower left screen, and right screen items are displayed for three screens. It may be displayed. Further, for example, the image of FIG. 2 may be displayed as it is in a state where the screens I (17a) and II (17b) can be selected, and the user may select them.

  FIG. 5 is a diagram for explaining another example of the registration processing of the divided screen area to be operated between the television apparatus exemplified in FIGS. 1 and 2 and the remote controller, and is another embodiment of the present invention. It is a figure for demonstrating the set of the television apparatus which concerns on, and a remote control.

  The set of the embodiment described with reference to FIG. 5 is basically the same as the embodiment described in FIG. 1 and FIG. 2 as the configuration example, but the control in the control unit 10 in the television apparatus 1 is different and the division is performed. It is not necessary to display an OSD image for selecting a screen area. Of course, an OSD display may be made during the registration process.

  First, it is assumed that the remote controller 3 in this embodiment also has the above-described transmission request operation key (ID setting key). This transmission request operation key is a key for making a transmission request for target screen information received by the ID receiving unit 32 in the key group 31. The key code transmission unit 34 transmits an operation key code corresponding to the input of the transmission request operation key.

  In the television apparatus 1, the operation code is received by the key code receiving unit 18, and the control unit 10 controls the IC tag 20 to execute the next process. The ID transmission unit 22 of the IC tag 20 reads and wirelessly transmits the ID in order among the plurality of target screen information (ID) stored in the memory 21 under the control of the control unit 10.

  In this embodiment, when the user changes the remote controller and makes an ID request in order for each remote controller, ID1, ID2, ID1, ID2,... (In the order of ID request, ID1, ID2,. ID3, ID1,...) Are registered. Therefore, for example, if ID requests are continuously executed by the same remote controller A, the ID registered in the remote controller A is first changed to ID1 and then rewritten to ID2.

  Here, the power supply of the IC tag 20 is preferably performed by the control unit 10 by a power supply control unit (not shown) when the operation signal corresponding to the transmission request operation key is received because power saving can be achieved. . For example, once the power is supplied, the supply may be continued for a predetermined time, and the IDs may be read in order only while the power is supplied. When power is supplied again, the first ID is read again.

  As described above, in the present embodiment, the target screen information transmitting unit described above transmits the target screen information in a predetermined order, so that it is necessary to display the OSD image for selecting the divided screen area and to be selected by the user. I try not to.

  With respect to the present embodiment, a registration processing example will be specifically described with reference to FIG. 5 on the assumption that the television device 1 can display a screen in two divisions as shown in FIG. First, the user A presses the transmission request operation key with the remote controller A (3a). At that time, as shown in FIG. 5A, the remote controller A (3a) transmits an operation signal including at least an operation key code for this key from the key code transmission unit 34, and the TV apparatus 1 uses the key code reception unit 18 to transmit this operation signal. Receives an operation signal. Then, in the television apparatus 1 that has received the operation signal by the key code receiving unit 18, the control unit 10 controls the ID transmitting unit 22 of the IC tag 20 to transmit ID1, and the ID transmitting unit 22 sets ID1. Read from the memory 21 and wirelessly transmit.

  In the remote controller A (3a), the ID receiving unit 32 receives the ID1 signal, and registers the transmission code corresponding to the received ID1 in the memory 33 as described with reference to FIG. The ID reception unit 32 can receive the ID by placing the remote controller A (3a) within the radio wave reachable range of the IC tag 20 when the transmission request operation key is pressed. Similarly, when the transmission request operation key is pressed on the remote control B (3b), the television apparatus 1 transmits the next ID, ID2, from the IC tag 20, and the remote control B (3b) can register a transmission code corresponding to ID2. .

  As described above, regarding the actual operation when ID1 and ID2 are set for the remote controls A (3a) and B (3b), that is, when the screen I (17a) and the screen II (17b) are set as operation targets, This is as described in FIG.

  The processing when there are three or more remote controllers is also as described above. Furthermore, the present embodiment can also be applied to a case where screen division display is possible with a plurality of screen division methods and the registration processing of this embodiment is applied to both screen division methods. As an example of a case in which three remote controls 3 are provided as a set and display is possible in two and three divisions, the ID transmission order is a left screen for two divisions, a right screen, an upper left screen for three divisions, a lower left screen, and a right You just have to decide on the condition of the screen. At this time, it is easy for the user to display the screen for which the ID is currently set by OSD display. At this time, if the screen corresponding to each ID is stored as the designation information in the internal memory of the control unit 10, the divided screen area to be operated can be determined. Alternatively, with the larger division number (here, three) as a reference, each of the two divided areas and the three divided areas are associated in advance as designation information in the internal memory of the control unit 10, and one of the divided screens When the registration process for the method is completed, the other registration process may be automatically completed.

  In this embodiment, the IC tag 20 that is an active RFID tag is used as the IC tag. However, one IC tag that is a passive RFID tag (for example, an IC tag 60 described later in FIG. 6) is employed. May be. In this case, an ID transmission / reception unit (for example, an ID transmission / reception unit 72 described later with reference to FIG. 6) may be provided on the remote control 3 side instead of the ID reception unit 32 to acquire an ID transmitted by making an ID transmission request. . Although the IC tag 60 will be described with reference to FIG. 6, unlike the embodiments described later, the IC tag 60 in this embodiment holds a plurality of IDs in the internal memory 61, and each time there is a request for an ID, Any device may be used as long as the ID is read from the memory 61 and transmitted. At that time, the remote controller does not need the above-described ID setting key, and an ID request can be made simply by being close to the IC tag 60.

  As another embodiment of the present invention, the transmission request operation key (ID setting key) as described above may not be provided on the remote control 3 side but may be provided on the television device 1 side. That is, the television apparatus 1 in the present embodiment includes a main body operation unit (not shown) that performs an operation. The main body operation unit may be mounted by providing a plurality of main body operation keys for inputting operations from the user, for example, on a portion of the frame of the casing of the television apparatus 1 that is positioned below the display 17 or an upper surface portion. This embodiment can be applied to the embodiment described in FIGS. 1 to 4 and the embodiment described in FIG.

  When applied to the embodiment described with reference to FIGS. 1 to 4, the control unit 10 in the present embodiment performs an IC operation when a predetermined operation (an operation such as the ID setting key described above) is performed on the main body operation unit. A menu image (for example, images 15a and 15b in FIG. 3) for selecting target screen information (ID) to be transmitted by the ID transmission unit 22 of the tag 20 is controlled to be OSD-displayed. Then, the ID transmission unit 22 transmits the ID selected by the selection operation on the main body operation unit while displaying the menu image. However, it is necessary to put only the remote controller 3 to register the ID corresponding to this selection operation within the radio wave reach of the IC tag 20.

  When applied to the embodiment described with reference to FIG. 5, the control unit 10 in this embodiment transmits IDs in order from the ID transmission unit 22 to the IC tag 20 when a predetermined operation is performed on the main body operation unit. Control to do. The ID reception unit 32 can receive the ID by placing the remote controller 3 within the radio wave reach of the IC tag 20 when performing the above-described predetermined operation on the main body operation unit. In the case of using a passive RFID tag in the embodiment of FIG. 5, this embodiment need not be particularly applied.

  As another embodiment according to the present invention, in the embodiment described with reference to FIGS. 1 to 4, the remote controller 3 is provided with a transmission request operation key corresponding to the number of divisions, and the user desires on the remote controller 3. The operation keys may be selected and input. When the operation key code corresponding to the transmission request for the target screen information transmitted from the remote controller 3 is received by the key code receiving unit 18 on the TV device 1 side, the ID transmission unit 22 of the IC tag 20 immediately receives the target key code. The screen information is configured to be transmitted wirelessly.

  For example, the control unit 10 of the television device 1 determines from the operation key code which operation screen key the transmission request operation key corresponds to, so that target screen information (ID ) Can be transmitted by the IC tag 20. In the present embodiment, when the operation key code corresponding to the transmission request is received, it is not necessary to display the OSD image and allow the user to select, as in the embodiment described with reference to FIGS.

  Similarly, as another embodiment, the transmission request operation keys for the number of divisions are provided on the television device 1 side like the above-described main body operation unit, and when a predetermined operation is performed, the ID transmission unit of the IC tag 20 22 may wirelessly transmit the meeting information.

  In each embodiment described with reference to FIGS. 1 to 4 and 5, in the set of FIG. 1, an RFID tag and a reader are used for transmitting target screen information (ID). May adopt other wireless communication methods such as short-range wireless communication other than the RFID method, infrared communication methods, wireless PANs such as Bluetooth (registered trademark), UWB, and Zigbee. In that case, the key code transmitting unit 34 and the key code receiving unit 18 may be integrated into the television apparatus 1 and the remote control 3 as a unit of a two-way wireless communication system.

  Moreover, in each embodiment described with reference to FIGS. 1 to 4 and FIG. 5, not only the target screen information (ID) and the transmission code for each divided screen area but also operations for all the divided screen areas can be executed. The target screen information (ID) and the transmission code for performing the setting may be prepared separately. This ID may be displayed so as to be selectable by the user as in the case of the divided screen area, or may be added to the ID that is transmitted in order. By setting this ID to the remote controller 3, it is possible to operate all the divided screen areas. The operations for all the divided screen areas here are operations that are effective for all areas among the operations for all the divided screen areas at the time of divided display, or operations that do not cause a big problem even if they are enabled (for example, volume adjustment, image quality adjustment). Etc.), for example, the channel switching operation may not be included.

  FIG. 6 is a diagram illustrating a configuration example of a set of a television device and a remote controller according to another embodiment of the present invention. In FIG. 6, 5 is a television device, 7 is a remote control, 60 is an IC tag (passive), 61 is a memory of the IC tag 60, 62 is an ID transmission / reception unit having an ID request reception unit and ID transmission unit, and 72 is an ID request transmission. An ID transmitting / receiving unit having an ID receiving unit and an ID receiving unit. Although a plurality of IC tags 60 are provided, they are omitted in FIG. The memory 61 stores one ID as the target screen information, and the ID transmission / reception unit 62 wirelessly transmits (transmits) the ID stored in the memory 61 in response to the ID transmission request without contact.

  In FIG. 6, 51 is a tuner unit 11, 52 is an external input unit 12, 53 is a video processing IC 13, 54 is an audio processing IC 14, 55 is a display device driver 15, 56 is a backlight unit 16, 57 is a display 17, 58 is a key code receiving unit 18, 59 is a speaker 19, 70 is a CPU 30, 71 is a key group 31, 73 is a memory 33, and 74 is a key code transmitting unit 34 corresponding to FIG.

  As described above, the TV apparatus 5 and the remote controller 3 illustrated in FIG. 6 replace the active RFID IC tag 20 with a plurality of passive RFID IC tags 60 in the TV apparatus 1 and the remote controller 7 of FIG. The ID receiving unit 32 is replaced with the ID transmitting / receiving unit 72, and the other components are basically the same, and thus the description thereof is omitted.

  In the television device 5 in the present embodiment, the target screen information transmission unit described above includes a plurality of request reception units that receive transmission requests from the remote controller 7. Further, it is assumed that these request reception units are arranged at positions corresponding to the respective divided screen areas. Then, when the above-described target screen information transmission unit receives a transmission request from the remote controller 7, the target screen information corresponding to each of the divided screen regions (target screen information assigned to each target screen information transmission unit) Send.

  In the present embodiment, the target screen information transmission unit is exemplified by the IC tag 60 (in fact, the ID transmission unit in the memory 61 and the ID transmission / reception unit 62). The request receiving unit is exemplified by the ID transmitting / receiving unit 62 of the IC tag 60 (actually, the ID request receiving unit).

  The remote controller 7 in this embodiment includes the following request transmission unit. This request transmission unit brings the remote controller 7 closer to one of the target screen information transmission units arranged at positions corresponding to each of the divided screen areas in the television device 5, so that the target screen information transmission unit The transmission request for the target screen information received by the target screen information receiving unit is made. This request transmission unit is illustrated as an ID request transmission unit in the ID transmission / reception unit 72, and the target screen information reception unit is illustrated as an ID reception unit in the ID transmission / reception unit 72. That is, the request transmission unit and the target screen information reception unit are exemplified by the ID transmission / reception unit 72 that is an IC tag reader that requests the IC tag 60 to transmit an ID and reads the ID transmitted from the IC tag 60.

  Further, not only the remote controller 7 is brought close to the target screen information transmitting unit, but also a transmission request operation key as described above is provided on the remote controller 7 so as to make a transmission request when the key is input. Is preferred. This is because it may occur that the remote controller 7 is operated close to the usage pattern.

  An example of registration processing in the set of the television device 5 and the remote controller 7 exemplified here will be specifically described with reference to FIGS. FIG. 7 is a diagram for explaining an example of the registration process of the split screen area to be operated between the television apparatus illustrated in FIG. 6 and the remote controller, and FIG. 8 is a remote control operation after the registration process of FIG. FIG. 9 is a diagram for explaining another example of the registration process of the divided screen area to be operated between the television apparatus illustrated in FIG. 6 and the remote controller.

  Also in the present embodiment, a registration process example will be described assuming that the television device 5 can display a screen in two. 7 and 8, the left side is the screen I (57a), the right side is the screen II (57b), and the IC tag 60 provided corresponding to each screen is the IC tag i (60a) and the IC tag ii (60b). ). Each of the IC tag i (60a) and the IC tag ii (60b) has an ID for operating the screen I (57a), and an ID for operating the screen II (57b) on the right side in the memory 61 so that transmission is possible. keeping.

  Further, FIGS. 7 and 8 show examples in which the IC tag i (60a) and the IC tag ii (60b) are arranged near the center of the left end of the screen I (57a) and near the center of the right end of the screen II (57b), respectively. ing. The signal effective ranges of the IC tag i (60a) and the IC tag ii (60b) must be kept from overlapping as much as possible. In such an arrangement example, it is possible to avoid duplication and to have a wider effective range. it can. Actually, since the radio wave of the passive IC tag is weak (effective distance is several tens of centimeters), if the display 17 is large, the signals (IDs emitted from both IC tags) do not interfere with each other. . Alternatively, it is possible to adjust the output so that the signals do not interfere with each other.

  7 and 8, the IC tag 60 is shown behind the display 57. However, even if there is an influence between the IC tag 60 and the display 57, it is only at the time of the registration process, so it is not necessary to consider it. Good. However, it is desirable to avoid only that the IC tag 60 transmits an ID due to processing at the time of video display including lighting of the backlight unit 56. If such an influence is taken into consideration, measures such as embedding in the frame of the housing may be taken, and the rear of the display at the corresponding position only when the frame of the casing is not on the outside of the corresponding screen, such as nine-screen display. It should be provided in.

  First, a case where the operation target of the remote controller A (7a) is set to the screen I (57a) will be described. As shown in FIG. 7 (A), the user A moves the remote controller A (7a) closer to the IC tag i (60a) and enters the effective range of the signal (pressing the transmission request operation key). I do. In response to the operation, the CPU 70 causes the ID transmitter / receiver 72 to execute an ID transmission request.

  The ID transmission / reception unit 72 emits an ID transmission request radio wave, and the ID transmission / reception unit 62 existing within the effective range that received the radio wave puts the ID on the reflected wave of the antenna. When the ID transmitter / receiver 72 receives this ID (ID1), the remote controller 7 acquires ID1. Here, as shown in FIG. 7A, since the remote control A (7a) is out of the effective range of the IC tag ii (60b), ID2 which is the ID for the screen II (57b) is acquired by mistake. There is no.

  In the remote control A (7a), the ID transmitter / receiver 72 receives the ID1 signal, and the CPU 70 reads out the transmission code corresponding to the received ID1 from the memory 73 and uses it as a transmission code representing the operation target at the time of split display. Register in the memory 73.

  Similarly, as shown in FIG. 7 (B), the user B puts the remote control B (7b) within the effective range of the IC tag ii (60b) and presses the transmission request operation key to start from the IC tag ii (60b). By acquiring ID2, a transmission code corresponding to ID2 can be registered by the remote controller B (7b). Of course, the user A may also make settings for the user B.

  As described above, the remote controller 7 stores the code system (transmission code) for each screen operation in the memory 73. When an ID is received, the code corresponding to the ID is read from the memory 73 and the operation key is set. I do.

  The set remote control can operate only the screen of the corresponding ID. FIG. 4 shows actual operations when ID1 and ID2 are set for the remote controls A (7a) and B (7b), that is, when the screen I (57a) and the screen II (57b) are set as operation targets. This is the same as the description explained.

  Therefore, as shown in FIG. 8A, since the remote control A (7a) includes a transmission code corresponding to ID1 in the operation signal, the TV apparatus 5 operates with the screen I (57a) as an operation target. II (57b) is not operated and does not operate. Similarly, as shown in FIG. 8B, in the remote control B (7b), the transmission code corresponding to ID2 is included in the operation signal. The screen I (57a) does not operate and does not operate.

  Also in the present embodiment, the same ID may be set on both the remote controllers A (7a) and B (7b), and if it is desired to operate a screen other than the corresponding ID screen after the setting, This can be done by acquiring the ID of the screen you want to operate using the method and redoing the key settings. Further, the processing when the full screen is displayed instead of the divided display, and the processing when the transmission code is not accompanied with the operation signal are as described in the explanation of FIG.

  Furthermore, this embodiment can also be applied to the case where there are three or more remote controllers or the case where there are three or more divided screens, as in the embodiments described with reference to FIGS. With respect to the case where there are four remote controls and display is possible in four divisions, a case where screens I (57a) to IV (57d) are set as operation targets in order by remote controls A to D with reference to FIG. explain.

  The television device 5 needs to be provided with IC tags 60a to 60d at positions corresponding to the respective divided screen areas of four divisions. For example, when the television tags 5 are provided at the four corners of the display 57 as shown in FIG. Good. Then, the remote controller A is brought close to the IC tag 60a and the transmission request operation key is pressed to register the remote controller A as an operation target of the screen I (57a). Similarly, the remote controls B, C, and D are moved closer to the IC tags 60b, 60c, and 60d, respectively, and the remote controller B, C, and D are respectively operated as the screen II (57b), the screen III (57c), and the screen. It can be registered as an operation target of IV (57d).

  Further, the present embodiment can also be applied to a case where screen division display is possible with a plurality of screen division methods and the registration processing of the present embodiment is applied to both screen division methods. A case will be described in which three remote controllers 7 are provided as a set and display is possible in two and three divisions. The effective range of each IC tag 60 is narrowed, and in addition to the IC tag i (60a) and IC tag ii (60b) for 2 divisions, the IC tag 60 for 3 divisions corresponds to the 3 division screen area It is preferable to set each remote controller 7 in advance. For example, in the case of two divisions and four divisions, an IC tag can also be used. Alternatively, the IC tag 60 having the larger number of divisions (three in this case) is arranged, and each of the two divided areas and the three divided areas are previously associated as designation information in the internal memory of the control unit 50. In addition, when the registration process for one screen division method is completed, the other registration process may be automatically completed.

  In the embodiment described with reference to FIGS. 6 to 9, in the set of FIG. 6, RFID-type tags and readers are used for transmission / reception of target screen information (ID). Other wireless communication systems such as an infrared communication system, a wireless PAN such as Bluetooth (registered trademark), UWB, and Zigbee may be adopted. In that case, it may be integrated with the key code transmission unit 74 and the key code reception unit 58 and mounted in the television apparatus 5 and the remote control 7 as one unit of a bidirectional wireless communication system.

  In addition, as in the embodiments described with reference to FIGS. 1 to 4 and 5, operations for all divided screen areas are not limited to target screen information (ID) and transmission codes for each divided screen area. Target screen information (ID) and a transmission code for performing settings so as to be executed may be separately prepared. When applied to the present embodiment, not only an IC tag for each divided screen area, but also an IC tag for performing settings so that an operation for all the divided screen areas can be executed. In this case, the remote controller 7 is brought close to the IC tags for all the divided screen areas so that the operation can be performed on all the divided screen areas in the same manner as the remote controller 7 is brought close to the IC tag 60 for the divided screen area. The remote controller 7 can be set.

  Although the remote control and video display device set of the present invention has been described above, the present invention may adopt a form as a setting method for registering and setting a transmission code related to target screen information in the remote control by the above processing procedure. Good.

  Further, the present invention is a control program that is incorporated in the video display device such as the above-described television devices 1 and 5 and causes the control unit exemplified by the control units 10 and 50 to execute the above-described processing on the video display device side. A form as (firmware) may also be adopted. Similarly, the present invention is configured as a control program (firmware) that is incorporated in a remote controller such as the above-described remote controllers 3 and 7 and causes the control unit exemplified by the CPUs 30 and 70 to execute the above-described processing on the remote controller side. May be adopted.
