Description

  The present invention relates to a video display device for displaying moving images and still images, and more particularly to a video display device that can be remotely controlled by infrared rays or the like and a control method for the video display device.

  Currently, a video display device represented by a television can be remotely operated by a small remote controller different from the display device body. The remote controller performs this remote operation by transmitting a remote control signal (generally, an infrared signal having a predetermined pattern) to the video display device.

  Further, this remote control signal is designed to be different depending on the manufacturer, model, and operation content of each electric device in order to avoid interference and erroneous operation with the remote control signal by the remote controller for other electric devices.

  Therefore, in order to instruct a predetermined operation to an electric device (including a video display device), it is necessary to operate a dedicated remote controller designed for the electric device.

  Further, as a means for operating without using the remote controller, the video display device main body is provided with a plurality of buttons, and by operating the buttons, the video display device can be operated (for example, channel change, volume change).

  However, in general, the number of buttons provided in the video display device main body is much smaller than the number of buttons of the remote controller due to design limitations and the like. Therefore, when an operation that can be performed by the remote controller cannot be realized by a button on the video display device main body, or an operation that can be achieved by a single press on the button of the remote control device requires a plurality of presses on the button of the video display device main body.

  In the first place, the video display device is mainly used for viewing videos away from the video display device, and it is considered that the user prefers remote operation by a remote controller.

  The above indicates that if the remote controller for the video display device is lost or the remote controller fails, the operation of the video display device is difficult or inconvenient for the user.

  In order to prevent such loss and failure of remote controllers and to aggregate a plurality of remote controllers, devices called “learning remote controllers” have been commercialized. This device can store remote control signals of other remote controllers and transmit the signals. Therefore, this learning remote controller can be used as an alternative to the dedicated remote controller for the video display device.

  For example, Patent Document 1 discloses the following mobile phone that can be used as a remote controller.

  That is, the mobile phone is equipped with a remote control signal generating means, connects to the Internet, downloads data that is the source of the remote control signal, and selects an electric device to be operated from the data.

  Similarly, for example, Patent Document 2 discloses the following apparatus capable of acquiring data for generating a remote control signal.

In other words, it is a device that can be connected to the Internet and has a remote control signal generation means, and obtains data for generating a remote control signal by inputting any one of the device name, manufacturer name, and model name. To do.
Patent 3739623 JP 2002-374484 A

  However, the “learning remote controller” has the following problems.

  That is, the remote control signal of the remote controller to be replaced in advance must be stored, and even if the learning remote controller is purchased after the dedicated remote controller is lost or broken, it cannot be learned.

  The techniques disclosed in Patent Documents 1 and 2 are based on acquiring a remote control signal for substituting for a dedicated remote controller by inputting information on an electrical device.

  However, there is a problem that not all users know the information of the electrical equipment that they are using. In particular, forcing the user to check the information on the electrical device (described in the manual or the back of the electrical device) in a situation where the remote control is lost or damaged may cause stress on the user. .

  An object of the present invention is to provide a video display device and a control method for the video display device that can easily provide a user with an alternative means of remote operation even in the case of loss or failure of a dedicated remote controller. is there.

  In order to achieve the above object, the video display device according to claim 1 is a video display device capable of displaying video, and an application program for generating a remote control signal for operating the video display device. Video display means for displaying the video for obtaining the image, receiving means for receiving the remote control signal from the device controlled by the application program, and controlling the video display device according to the received remote control signal And a control means for performing.

  The video display device control method according to claim 4 is a video display device control method capable of displaying video, and acquires an application program for generating a remote control signal for operating the video display device. A video display step for displaying a video for receiving, a reception step for receiving the remote control signal from a device controlled by the application program, and a control step for controlling the video display device according to the received remote control signal It is characterized by having.

  As described above, according to the present invention, the video display device infers the loss or failure of the remote controller, and displays information for acquiring an application program for a portable electronic device such as a mobile phone on the video display device according to a user instruction. Can do. Furthermore, by downloading an application program to the portable electronic device, the portable electronic device can be used as a remote controller suitable for the video display device.

  Therefore, even when the dedicated remote controller is lost or broken, it is possible to easily provide the user with an alternative means of remote operation.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a video display apparatus according to an embodiment of the present invention.

  In FIG. 1, a main controller board 100 is configured by units 101 to 110 described later, and controls the entire operation of the video display device.

  External video signals (analog TV signal, digital TV signal, composite signal, component signal, HDMI signal, etc.) are input to the board 100 and processed through a connector (not shown) provided in the video display device. The processed signal is transferred to a display panel unit 111, which will be described later, and presented in a form that can be viewed by the user.

  The CPU 101 is a processor for controlling the entire main controller board 100 and operates according to a program stored in a ROM 102 or RAM 103 described later.

  The ROM 102 is a non-volatile memory in which the CPU 101 program and fixed data are stored. When the power of the video display device is turned on, the CPU 101 reads a program from the ROM 102 and starts controlling the video display device.

  The RAM 103 is a volatile memory for temporarily storing various data. A video memory for storing intermediate processed data and processed data of a video signal, and a program executed by the CPU 101 are used as a working space for storing data.

  The tuner 104 is a unit that selects a specific frequency band from the received analog signal and converts it into a digital signal that can be processed by the CPU 101. For example, when the input is a terrestrial analog signal, an NTSC signal is generated, further converted into a digital signal (ITU-R BT.656) and input to the CPU 101. On the other hand, when the input is a terrestrial digital signal, it is demodulated into MPEG-2TS data and input to the CPU 101.

  The I / O unit 105 includes a USB controller, an IEEE 1394 controller, and a network controller, and is used to connect an external digital video output device (not shown). Examples of the digital video output device include a digital still camera, a digital video camera, and a network video server.

  The CPU 101 can acquire video data from an external digital video output device via the unit 105. The I / O unit 105 includes a memory card controller (an SD card controller, a compact flash (registered trademark) controller, a memory stick controller, etc.), and the CPU 101 can read video data in the memory card.

  Video processor 106 is an application specific processor for processing digital video signals. The video processor 106 has a command set suitable for video processing such as SIMD arithmetic processing commands, and can perform processing such as resolution conversion, video data overlay, and color conversion in real time. Note that the video processor 106 may be integrated in the CPU 101.

  The display controller 107 is an IC for transferring the digital video signal processed by the video processor 106 to the display panel unit 111 with a predetermined clock and format.

  The UI (user interface) unit 108 includes a plurality of buttons which will be described later with reference to FIGS. These buttons are installed in the video display device body, and the CPU 101 can detect the state of the buttons.

  The IR controller 109 includes an element that receives an infrared signal from a remote controller, which will be described later with reference to FIG. 4, and a control IC that decodes the infrared signal to obtain a remote control command. The CPU 101 can acquire the remote control command received by the IR controller 109.

  Each unit is connected by a system bus 110.

  The display panel unit 111 includes a display driver IC for receiving a signal output from the display controller 107 and a display panel for visualizing the signal. For example, a combination of a liquid crystal driver IC and a liquid crystal display panel.

  FIG. 2 is an external view of the video display apparatus according to the embodiment of the present invention.

  In FIG. 2, a frame 200 is a part that constitutes a casing of the video display device. Units 201 to 204 described later are incorporated in the frame 200, and the main controller board 100 of FIG. 1 is stored in the frame 200.

  The display panel 201 constitutes the display panel unit 111. The final video signal is displayed on this panel and the user can watch the video.

  The speaker unit 202 is a device for converting an audio signal into air vibration and outputting it as a form that can be heard by the user.

  The button group 203 constitutes the UI unit 108. The button group 203 will be described later in detail with reference to FIG.

  The infrared signal light receiving unit 204 has a function of receiving infrared light. An IR controller 109 is installed in the back of the infrared signal light receiving unit 204 and can receive the infrared light that has passed through the infrared signal light receiving unit 204. The user can remotely operate the video display device by transmitting an infrared signal to this area.

  FIG. 3 is an enlarged view of the button group in FIG.

  As can be seen from this figure, the operation input unit provided in the main body of the video display apparatus is composed of seven buttons (keys).

  Button 301 is a main power button. The user can change the power supply state of the video display device with the main power button 301. For example, when the main power button 301 is pressed during the operation of the video display device, the processing of this device including video display can be stopped as much as possible, and the power consumption of the video display device can be reduced.

  When the power is turned off with the power button of the remote controller, which will be described later with reference to FIG. 4, the video display device shifts to a standby state. In this state, video display is not performed, but some processing of the video display device continues. Is done.

  For example, information of an electronic program guide called EPG is updated even in a standby state. The main power button 301 has a built-in LED that emits red and green light, and emits green light when the power is on and red light when in the standby state.

  Button 302 is a menu button. The user can display a menu on the display panel 201 by pressing the menu button 302. The user can perform part of the processing of the video display device by operating this menu.

  Buttons 303 and 304 are channel selection buttons. The user can change the channel of the displayed video by using these channel selection buttons 303 and 304.

  Buttons 305 and 306 are volume change buttons. The user can change the volume of the sound output from the speaker unit 202 with these volume change buttons 305 and 306.

The button 307 is a support button. The user can display the operation method of the video apparatus on the display panel 201 by pressing the support button 307.
The support button 307 has a built-in LED that emits yellow light, and the CPU 101 executes control for emitting the LED under a predetermined condition (described later in the operation description).

  FIG. 4 is an external view of a remote controller for remotely operating the video display device of FIG.

  In FIG. 4, an infrared signal light emitting unit 401 is an area for emitting a remote control command encoded in an infrared signal. When the infrared signal emitted from the infrared signal light emitting unit 401 is received by the infrared signal light receiving unit 204, various buttons pressed by the remote controller are notified to the main controller board 100 as remote command signals.

  As shown in FIG. 4, the remote controller includes a large number of buttons, and the user can perform many processes (specific channel selection and the like) with one touch. In addition, cross keys and the like representing up, down, left, and right are provided, and a more convenient operation feeling can be provided to the user. Therefore, the majority of users operate the video display apparatus by the remote controller shown in FIG.

  The operation of the video display apparatus will be described based on a flowchart.

  FIG. 5 is a flowchart showing a procedure of processing corresponding to a user operation (reception of a remote control command or pressing of a main body key) executed by the video display device of FIG.

  In processing this flowchart, the CPU 101 holds one variable and one constant. The variable is a counter (hereinafter referred to as a main body key counter) that records the number of operations of the main body key (button group 203), and the constant is treated as a threshold for the main body key counter. The main body key counter is set to zero when the video display device is turned on.

  In FIG. 5, first, in step S501, the CPU 101 investigates the remote control command received by the IR controller 109. If a remote control command has been received, the process proceeds to step S502. If not received, the process proceeds to step S503.

  In step S502, the CPU 101 clears the main body key counter to zero, and proceeds to step S507.

  On the other hand, in step S503, the CPU 101 investigates the pressed state of the main body key. If the main body key has not been pressed, the process returns to step S501 and the remote control command reception state is checked again. If it is detected that the main body key is pressed, the process proceeds to step S504.

  In step S504, the CPU 101 increments the main body key counter by one. Note that “++” in step S504 in FIG. 5 is a symbol meaning to increment the value of the key counter.

  In step S505, the CPU 101 compares the current value of the main body key counter with the aforementioned threshold value. If the main body key counter is larger than the threshold, the process proceeds to step S506, and if it is equal to or smaller than the threshold, the process proceeds to step S507. That is, step S505 is processing for comparing a user operation on the main body key with a predetermined input condition.

  In step S <b> 506, the CPU 101 operates the UI unit 108 to turn on the LED embedded in the support button 307.

  Therefore, for example, if the threshold value is 10, the support button 307 will light up if the continuous operation is performed 11 times with only the main body key.

  In step S507, processing according to the remote control command received by the CPU 101 or the detected main body key is performed. For example, when the volume change on the main body is pressed, the level of the sound output from the speaker unit 202 is changed. When a “power command (pressing the power button on the remote control)” is detected as a remote control command, a transition to the standby state (or return from the standby state) is performed. That is, in the case where the user continuously operates the main body key a number of times exceeding the threshold value, the CPU 101 lights the support button 307. However, processing corresponding to the user's body key is always executed until the threshold is exceeded. For example, channel change or audio level change.

  FIG. 6 is a flowchart showing the procedure of the support button pressing process characteristic of the present invention among the processes executed in step S507 of FIG.

  In FIG. 6, first, in step S <b> 601, the CPU 101 records the current state of the video display device in the RAM 103. This is because the display content of the display panel 201 is changed in the subsequent processing.

  For example, when the operation menu is displayed on the display panel 201, the information is stored so that the same menu can be displayed again after the display content is changed.

  In step S <b> 602, the CPU 101 confirms the display state of the LED of the support button 307. When the LED is not turned on (that is, whether or not step S506 has been passed in the flowchart of FIG. 5), the subsequent processing contents are different.

  Step S603 is processing when the LED is not lit. In this case, the CPU 101 changes the display content of the display panel 201 and displays a help message corresponding to the current state of the video display device.

  For example, if the user presses the menu button 302 and the menu is displayed on the display panel 201, an explanation document of the menu displayed in response to the pressing of the support button 307 is displayed. When the help message display process ends, the process proceeds to step S606.

  On the other hand, steps S604 and S605 are processes when the LED is lit.

  In step S604, the CPU 101 changes the display content of the display panel 201 to the content shown in FIG.

  Here, the flowchart of FIG. 6 will be left and FIG. 7 will be described.

  FIG. 7 is a diagram showing a state in which the display panel in FIG. 2 displays information for acquiring the remote control application program.

  In FIG. 7, a character string 701 is a URL representing a Web site that can be accessed by a mobile phone. This URL is information indicating an acquisition destination for acquiring a remote control application described later.

  This character string differs depending on the model of the video display device. In other words, one URL is assigned to each model of the video display device. The display contents at this URL will be described later with reference to FIGS.

  A display mark 702 is a two-dimensional code standardized by ISO / IEC 18004 in which a character string 701 is encoded. The user can easily acquire the character string 701 by photographing and recognizing the two-dimensional code 702 with a camera attached to the mobile phone. A character string 703 is an explanation for terminating the display of this screen.

  Returning to the flowchart of FIG. 6, in step S605, the LED of the support button 307 is turned off.

  In step S606, the CPU 101 waits for the support button 307 to be pressed again. If it is pressed, the CPU 101 returns the state of the video display device to the state stored in step S601, and ends this flowchart.

  Next, with reference to FIG. 8 to FIG. 11, the situation and effects when the video display apparatus is used will be described.

  FIG. 8 is a conceptual diagram of the video display apparatus control system according to the embodiment of the present invention.

  In FIG. 8, the video display device 801 has a function of receiving an infrared signal from a remote controller and a function of displaying a two-dimensional code representing a URL on the screen as described above.

  The mobile phone 802 is a general mobile phone currently on the market, and has a camera function, an infrared signal light emitting unit 803, and a function of connecting to the Internet. In addition, an application program execution function and a display capable of changing display contents by control by the application program are provided.

  The Web server 804 holds a Web page that can be displayed on the mobile phone 802, an application program that can be executed on the mobile phone 802, and the like.

  The network 805 includes a mobile phone network and an Internet network held by a mobile phone operator. The mobile phone 802 can communicate with the Web server 804 via the network 805.

  FIG. 9 is a diagram showing a screen of the mobile phone when accessing the Web site represented by the character string 701 in FIG.

  On this screen, a link for downloading an application program (hereinafter referred to as a remote control application) that operates on the mobile phone 802 is set (download button 901). The user can download and store the remote control application on his / her mobile phone 802 from this link.

  FIG. 10 is a diagram showing a screen of the mobile phone when the remote control application is downloaded from the screen of FIG. 9 and executed on the mobile phone.

  As shown in this figure, a remote control diagram 1001 having the same appearance as the remote controller described in FIG. 4 is drawn and displayed on the screen of the mobile phone. Remote control FIG. 1001 is provided with a selectable graphical button at the same position as the button arrangement of the remote controller of FIG. 4 (display 1002 indicates that the channel 1 button is being selected).

  FIG. 11 is a flowchart showing the button processing procedure of the mobile phone body when the remote control application downloaded from the screen of FIG. 9 is activated (state of FIG. 10). The following steps are incorporated in the mobile phone and executed by a control unit (not shown) that operates the remote control application.

  In FIG. 11, first, in step S1101, the control unit determines whether or not the button of the mobile phone body is pressed. If the button is pressed, the process proceeds to step S1102 and subsequent steps.

  In step S1102, the control unit determines whether or not a direction key (up / down / left / right key) among the keys of the mobile phone body is pressed. When the direction key is pressed, the control unit changes the display so that the pressed button is visible in the remote control diagram 1001 displayed on the screen of the mobile phone (step S1103).

  For example, when the channel 1 button is being selected as shown in FIG. 10, if it is detected that the right key has been pressed, the channel 2 button is changed to being selected in the display of the remote control diagram 1001.

  In step S1104, the control unit determines whether or not a selection key (or determination key) among the keys of the mobile phone body has been pressed. When the selection key is pressed, the control unit transmits (emits) a remote control signal according to the graphical button selected in step S1103 from the infrared signal light emitting unit 803 as an infrared signal (step S1105).

  When this signal is transmitted toward the video display device and received (received) by the infrared signal light receiving unit 204, the video display device performs the same operation as when the button of the actual remote controller is pressed.

  Therefore, the mobile phone 802 on which the remote control application is executed can be used as if it were a remote controller attached to the video display device.

  In step S1106, the control unit determines whether a key corresponding to the help button among the buttons on the mobile phone body has been pressed. When a key corresponding to the help button is pressed, a screen (not shown) for explaining how to use the remote control application is displayed on the screen of the mobile phone 802 (step S1107).

  In step S1108, the control unit determines whether a key corresponding to the end button among the buttons on the mobile phone body has been pressed. When the key corresponding to the end button is pressed, this program ends.

  As described above, according to the present embodiment, the video display device infers that the remote controller is lost or malfunctioned, and displays information for acquiring an application program for a mobile phone on the video display device according to a user instruction. be able to.

  Furthermore, by downloading the application program to the mobile phone 802, the mobile phone 802 can be used as a remote controller suitable for the video display device.

  Therefore, even when the remote controller is lost or broken, the user can accurately operate the video display device by using the mobile phone 802 instead of the remote controller.

  As another embodiment, an example is shown in which the video display device does not infer the loss or failure of the remote controller and the user displays the screen of FIG. In this embodiment, differences from the above embodiment will be described.

  FIG. 12 is a diagram showing the contents displayed on the display panel in FIG. 2 when the menu button in FIG. 3 is pressed.

  The menu 1201 is a menu that displays items that can be selected by the user, and the user can select items by using the channel selection buttons 303 and 304 of the video display device main body or the up and down keys of the remote controller in FIG. In FIG. 12, the outer frame 1202 indicates that “support” is selected.

  When the user presses the menu button 302 of the video display device or the determination key of the remote controller in FIG. 4 while the menu item is selected, the lower level of the menu item is displayed or the function associated with the menu is displayed. Execute.

  In FIG. 12, a lower layer exists with a triangle pointing to the right. Therefore, when the user selects “support” and presses the menu button 302, a lower-level menu 1301 is displayed as shown in FIG.

  FIG. 13 is a diagram showing the contents displayed on the display panel in FIG. 2 when “support” in FIG. 12 is selected.

  FIG. 14 is a flowchart showing the procedure of the menu display process of FIGS. 12 and 13 executed by the video display apparatus of FIG.

  14, in step S1401, the CPU 101 waits for reception of a remote control signal when the menu button 302 of the video display device main body is pressed or when the key of the remote controller of FIG. 4 is pressed.

  In step S1402, the CPU 101 displays the menu shown in FIG. 12, updates the menu item being selected in accordance with the user's operation (channel selection buttons 303 and 304 or the up and down keys of the remote controller), and selects the menu item in step S1403. Wait for it.

  In step S1404, the CPU 101 selects whether the selected menu item is an end menu item. When the end menu item is selected, the menu display is ended, and the display content of the display panel 201 is returned to the state before the menu display. If any item other than the end menu item is selected, the process proceeds to step S1405 and subsequent steps.

  In step S1405, the CPU 101 selects whether or not a remote control acquisition menu item (reference numeral 1302 in FIG. 13) has been selected. In the present embodiment, since this menu item is a feature of the present invention, the processing content when it is pressed will be described in step S1406 and step S1407.

  In step S1405, when the CPU 101 recognizes that the remote control acquisition menu item has been selected, the CPU 101 executes processing for changing the content of the display panel 201 to the content of FIG. 7 (step S1406). The processing performed here is almost the same as the content described in the flowchart of FIG.

  In step S1407, when the CPU 101 detects that the support button 307 has been pressed, the CPU 101 ends the display of FIG. 7 and returns to the menu display status.

  On the other hand, if the selected menu item is other than the remote control acquisition menu item in step S1405, the CPU 101 performs processing according to the menu item (step S1408). The processing here is not directly related to the present embodiment and will not be described.

  As described above, according to the present embodiment, the video display device includes means for displaying information for acquiring an application program for a mobile phone. The user confirms the display and downloads the application program to the mobile phone 802 as necessary. Thus, the cellular phone 802 can be used as a remote controller suitable for the video display device.

  Therefore, even when the remote controller is lost or broken, the user can easily use the mobile phone 802 instead of the remote controller by the above means, and can accurately operate the video display device.

  In the above embodiment, an infrared signal is used as a remote control means. However, the present invention is not limited to this, and wireless communication means such as Bluetooth, IEEE 802.11 (wireless LAN), wireless USB or the like is used. There may be.

  In the above embodiment, the mobile phone 802 is used as a device that transmits a remote control signal to the video display device, but the present invention is not limited to this. An electric device such as a digital camera or PDA that can be connected to a network and can transmit a remote control signal may be used.
