PRIORITY 
       [0001]    This application is a Continuation of U.S. application Ser. No. 13/177,091, filed on Jul. 6, 2011, which claims priority from Korean Patent Application No. 10-2010-0101962, filed on Oct. 19, 2010 in the Korean Intellectual Property Office, the disclosures of which are incorporated herein in their entirety by reference. 
     
    
     BACKGROUND 
       [0002]    1. Field 
         [0003]    Methods and apparatuses consistent with exemplary embodiments relate generally to a method for controlling a bidirectional remote controller and a bidirectional remote controller implementing the method, and more particularly, to a method for controlling a bidirectional remote controller and a bidirectional remote controller implementing the method, which can control a display device. 
         [0004]    2. Description of the Related Art 
         [0005]    Generally, a remote controller is a device that remotely controls electronic appliances, such as a television receiver, a DVD (Digital Versatile Disc), a VCR (Video Cassette Recorder), a cable broadcasting device, a set top box, an audio device, and the like through wireless transmission of a control frequency. For this, the remote controller transmits a control signal to a remotely controlled electronic appliance, for example, using an infrared signal. 
         [0006]    For example, as illustrated in  FIG. 1 , a display device  110  unidirectionally receives only a simple signal, such as a channel change signal, a volume control signal, and the like, by a remote controller  120 . 
         [0007]    However, in controlling a display device  110  such as a television receiver, a menu screen is displayed using an on-screen display (OSD). However, as the functions and complexity of processing and displaying images on the screen are increased, it is inconvenient to input navigation, selection, and characters of OSD on the screen using a remote controller. 
         [0008]    For example, since a user is required to search for and set a desired function, such as when reviewing an instruction manual in a display device, the user looks at instruction manual on the screen, exits the OSD containing the instruction manual, and returns to another OSD of the screen to perform the desired operation. Also, there is an increasing need for a special pointing device or character input function in order to perform Internet browsing.

     DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
       [0037]    Hereinafter, exemplary embodiments are described in detail with reference to the accompanying drawings. For reference, in explaining the exemplary embodiments, detailed descriptions of constructions or processes known in the art may be omitted to avoid obscuring the subject matter of the exemplary embodiments. 
         [0038]      FIG. 2  is a diagram illustrating an example in which a bidirectional remote controller according to an exemplary embodiment controls a display device. 
         [0039]    As illustrated in  FIG. 2 , a bidirectional remote controller  220  according to an exemplary embodiment performs bidirectional communication with a display device  210 . 
         [0040]    Also, the display device  210  may transmit an OSD menu screen for control of the display device to the bidirectional remote controller  220 , and the bidirectional remote controller  220  may transmit a control command for displaying an active window that corresponds to a menu screen selected by a user or a control command for executing a function that corresponds to the menu screen selected by the user to the display device  210 . 
         [0041]    Accordingly, an OSD menu screen for controlling screen brightness, contrast, and the like is displayed on the bidirectional remote controller. 
         [0042]      FIG. 3  is a brief block diagram of a bidirectional remote controller according to an exemplary embodiment illustrated in  FIG. 2 . As illustrated in  FIG. 3 , the bidirectional remote controller  220  includes a reception unit  221 , a display unit  223 , a function execution unit  225 , a transmission unit  227 , and a user command input unit  229 . 
         [0043]    The reception unit  221  receives the menu screen for controlling the display device  210  from the display device  210 . 
         [0044]    In an exemplary embodiment, the reception unit  221  may receive the menu screen in an XML data format from the display device  210 . 
         [0045]    Here, the XML data format represents a method for describing schema using an XML (Extensible Markup Language) grammar, and is an XML application for defining metadata schema. 
         [0046]    In an exemplary embodiment, the menu screen may include at least one of an OSD menu screen and an e-manual screen of the display device. 
         [0047]    Here, the OSD menu screen may be a screen for setting a screen or sound of the display device. 
         [0048]    In other words, through the menu screen, the OSD, manual, and the like of the display device  210  that is a main video appliance can be received. 
         [0049]    For example, the OSD may be an OSD menu screen for setting a screen or sound of the display device or an e-manual that is a user guide for the display device. 
         [0050]    Accordingly, the bidirectional remote controller according to an exemplary embodiment can directly receive the OSD screen for controlling the display device, and can set the screen or sound desired by the user. 
         [0051]    The display unit  223  of the bidirectional remote controller  220  outputs the menu screen received by the reception unit  221  from the display device  210 . 
         [0052]    Here, the bidirectional remote controller  220  may be a remote controller that includes a touch screen or a display unit. 
         [0053]    In other words, since the bidirectional remote controller  220  according to an exemplary embodiment receives the OSD screen or the like from the display device  210  and displays the OSD screen on the bidirectional remote controller  220 , the bidirectional remote controller  220  should include a display unit such as a touch screen. 
         [0054]    Also, in an exemplary embodiment, the display unit  223  of the bidirectional remote controller  220  may install a program in the bidirectional remote controller  220  for configuring the menu screen received by the reception unit  221  in the XML data format. 
         [0055]    Accordingly, it is necessary to install the OSD screen received from the display device  210  in the bidirectional remote controller  220  in order to control the display device. 
         [0056]    If at least one menu is selected from the menu screen, the function execution unit  225  generates at least one of the control command for displaying an active window that corresponds to the selected menu and the control command for executing a function that corresponds to the selected menu on the display device. 
         [0057]    In other words, if the user selects any one of the OSD menu screen or e-manual screen received from the display device  210 , the function execution unit  225  generates the control command that executes the function that corresponds to the selected item. 
         [0058]    The transmission unit  227  transmits the control command generated by the function execution unit  225  to the display device  210 . 
         [0059]    In an exemplary embodiment, the transmission unit  227  can transmit the control command for immediately displaying the active window to the display device  210  in the case where any one of the menu screens displayed on the bidirectional remote controller  220  is selected by the user. 
         [0060]    In other words, if the user selects any one of diverse menu items on the remote controller, the transmission unit of the bidirectional remote controller according to an exemplary embodiment transmits the control command for immediately displaying the active window that corresponds to the selected menu item on the display device  210  to the display device  210 . Accordingly, the user can perform all settings for the screen or sound on the bidirectional remote controller  220  without the necessity of operating the OSD menu screen on the display device  210 . 
         [0061]    Here, the active window that corresponds to the selected menu screen may have its inherent ID, and the control command for displaying the active window that corresponds to the selected menu screen may include the inherent ID. 
         [0062]    In other words, in order to immediately display the active window that corresponds to the menu screen selected on the bidirectional remote controller  220  on the display device  210 , the inherent ID such as an index ID is given to each active window that corresponds to the menu screen selected on the bidirectional remote controller  220 , and if the inherent ID that displays the active window is included in the control command, the display device  210  immediately displays the active window that corresponds to the inherent ID transmitted from the bidirectional remote controller  220 . 
         [0063]    In an exemplary embodiment, if a plurality of menus are selected, the transmission unit  227  may transmit the control commands that correspond to the plurality of menus individually or collectively. 
         [0064]    In other words, the transmission unit  227  may individually transmit the control command according to the menu selected by the user in the function execution unit whenever the control command is generated, or may collectively transmit the control command to the display device after all settings are completed. 
         [0065]    Here, the control command may include a control command for storing the data input by the bidirectional remote controller  220  in the display device  210 . 
         [0066]    In other words, the control command may include not only the control command according to the menu screen for controlling the display device  210  through the remote controller but also the control command for storing the user input data, such as characters input through the remote controller or setting data changed by the bidirectional remote controller  220 , in the display device  210 . 
         [0067]    The user command input unit  229  receives the user input from the user. 
         [0068]    That is, the function execution unit  225  receives the user input for executing a function that corresponds to the menu selected by the user. 
         [0069]    In an exemplary embodiment, the transmission unit  227  may transmit the data that corresponds to the user input received by the user command input unit  229  to the display device  210 . 
         [0070]    For example, the character input data input through the user command input unit can be transmitted to the display device  210 . 
         [0071]    Also, in an exemplary embodiment, the bidirectional remote controller  220  can perform not only the function of a remote controller for one display device but also the function of an integrated remote controller for a plurality of display devices. 
         [0072]    Accordingly, the bidirectional remote controller  220  according to diverse exemplary embodiments can immediately transmit the settings desired by the user to the display device  210  for storage as the user watches the setting and operation explanation of the display device on the remote controller in the case of using contents such as an e-manual or the like. Also, it is possible to freely operate the OSD menu screen on the screen without discriminating the OSD menu screens displayed on the display device. Also, in the case of setting navigation of the OSD menu screen using the bidirectional remote controller  220 , the user&#39;s input of touch, instruction, character input, and the like, can be freely performed. 
         [0073]    Hereinafter, a method for controlling a bidirectional remote controller  220  according to an exemplary embodiment will be described. In the following description, explanation that overlaps the above-described explanation of the bidirectional remote controller according to an embodiment of the invention will be omitted. 
         [0074]      FIG. 4  is a flowchart illustrating a method for controlling a bidirectional remote controller according to an embodiment of the invention. 
         [0075]    First, the bidirectional remote controller  220  receives a menu screen from the display device  210  and displays the menu screen (S 410 ). 
         [0076]    Here, the bidirectional remote controller  220  may be a remote controller that includes a touch screen remote controller or a display unit. In other words, since the bidirectional remote controller  220  according to an exemplary embodiment receives the OSD screen or the like from the display device  210  and displays the OSD screen on the bidirectional remote controller  220 , it should include a display unit such as a touch screen. 
         [0077]    In an exemplary embodiment, the menu screen may include at least one of an OSD menu screen and an e-manual screen of the display device  210 . 
         [0078]    Here, the OSD menu screen may be a screen for setting a screen or sound of the display device. 
         [0079]    In other words, through the menu screen, the OSD, manual, and the like, of the display device  210  that is a main video appliance can be received from the display device  210 . 
         [0080]    For example, the OSD may be an OSD menu screen for setting a screen or sound of the display device  210  or an e-manual that is a user guide for the display device  210 . 
         [0081]    Accordingly, the bidirectional remote controller  220  according to an exemplary embodiment can directly receive the OSD screen for controlling the display device  210 , and can set the screen or sound desired by the user. 
         [0082]    In an exemplary embodiment, the menu screen may be received in an XML data format from the display device  210 . 
         [0083]    Here, receiving the menu screen from the display device  210  and displaying the menu screen on the bidirectional remote controller  220  may include installing a program for configuring the menu screen received in the XML data format in the bidirectional remote controller  220 . 
         [0084]    This is because an installation program for displaying the OSD screen received from the display device is required in order to receive the OSD screen for controlling the display device  210  in the bidirectional remote controller  220  and to control the display device  210  accordingly. 
         [0085]    Next, a menu is selected from the menu screen displayed in operation S 410  (S 430 ). 
         [0086]    According to the method for controlling a bidirectional remote controller  220  according to an exemplary embodiment, a user selects any one of the OSD menu screen and e-manual received from the display device  210 . 
         [0087]    Last, at least one of a control command for displaying an active window that corresponds to the menu screen selected in operation S 430  and a control command for executing a function that corresponds to the selected menu on the display device  210  is transmitted to the display device  210  (S 450 ). 
         [0088]    Here, the method for controlling a bidirectional remote controller  220  according to an exemplary embodiment may further include receiving a user input from the user and transmitting data that corresponds to the user input to the display device  210 . 
         [0089]    In an exemplary embodiment, the control command for displaying the active window that corresponds to the selected menu screen on the display device  210  may be a control command for immediately displaying the active window in the case where any one menu is selected by the user from the menu screens displayed on the bidirectional remote controller  220 . 
         [0090]    In other words, if the user selects any one of diverse menu items on the bidirectional remote controller  220 , the control command for immediately displaying the active window that corresponds to the selected menu item on the display device  210  is transmitted to the display device  210 . Accordingly, the user can perform all settings for the screen or sound on the bidirectional remote controller  220  without the necessity of operating the OSD menu screen on the display device  210 . 
         [0091]    Here, the active window that corresponds to the selected menu screen may have its inherent ID, and the control command for displaying the active window that corresponds to the selected menu screen may include the inherent ID. 
         [0092]    Therefore, in order to immediately display the active window that corresponds to the menu screen selected on the bidirectional remote controller  220  on the display device  210 , the inherent ID such as an index ID is given to each active window that corresponds to the menu screen selected on the bidirectional remote controller  220 , and if the inherent ID that displays the active window is included in the control command, the display device  210  immediately displays the active window that corresponds to the inherent ID transmitted from the bidirectional remote controller.  220   
         [0093]    In an exemplary embodiment, if a plurality of menus are selected, operation S 450  may transmit the control commands individually or collectively. 
         [0094]    In other words, the control command according to the menu selected by the user may be individually transmitted whenever the control command is generated, or may be collectively transmitted to the display device  210  after all settings are completed. 
         [0095]    Here, the control command may include a control command for storing the data input by the remote controller in the display device. 
         [0096]    In other words, the control command may include not only the control command according to the menu screen for controlling the display device  210  through the bidirectional remote controller  220  but also the control command for storing the user input data, such as characters input through the remote controller or setting data changed by the bidirectional remote controller  220 , in the display device  210 . 
         [0097]    Accordingly, the method for controlling a bidirectional remote controller  220  according to diverse exemplary embodiments can immediately transmit the settings desired by the user to the display device  210  for storage as the user watches the setting and operation explanation of the display device  210  on the remote controller in the case of using contents such as an e-manual or the like. Also, it is possible to freely operate the OSD menu screen on the screen without discriminating the OSD menu screens displayed on the display device  210 . Also, in the case of setting navigation of the OSD menu screen using the bidirectional remote controller  220 , the user&#39;s input of touch, instruction, character input, and the like, can be freely performed. 
         [0098]    While the inventive concept has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the inventive concept, as defined by the appended claims.
