Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to an audiovisual apparatus. More specifically, the present invention relates to an audiovisual apparatus including a display monitor and a remote control unit.  
         [0003]     2. Description of the Related Art  
         [0004]     Conventionally, an audiovisual apparatus (hereinafter, “AV apparatus”), e.g., a television receiver can display a user setting screen. On this user setting screen, a user can set various conditions such as those for a video, a voice, a channel and the like of the television receiver using a remote control unit so as to optimally match to a user&#39;s utilization state of the television receiver.  
         [0005]     If the number of setting types increases, the user needs to make many settings using one remote control unit. A setting operation is sometimes, therefore, not easy for the user to perform.  
         [0006]     To facilitate the setting operation using the remote control unit, Patent Literature 1 proposes a technique intended to provide guide means for informing the user of a key operation in the remote control unit. With this proposed technique, however, the AV apparatus is required to include means for holding a two-way communication with the remote control unit. As a result, it is disadvantageously necessary to include additional hardware in the AV apparatus and a manufacturing cost of the AV apparatus is disadvantageously increased.

       SUMMARY OF THE INVENTION  
       [0008]     It is an object of the present invention to facilitate a setting operation using a remote control unit without increasing a manufacturing cost of an AV apparatus.  
         [0009]     To attain the object, according to the present invention, there is provided an audiovisual apparatus including a display monitor and a remote control unit, and comprising: means for displaying a setting screen, on which a user performs a setting operation for the audiovisual apparatus using the remote control unit, on the display monitor; and means for displaying a keypad pattern of the remote control unit used for the setting operation for the audiovisual apparatus, on the setting screen. Further, to attain this object, there is also provided an audiovisual apparatus further comprising means for displaying a key used for the setting operation for the audiovisual apparatus, on the displayed keypad while marking the key.  
         [0010]     These means provided by the present invention enable the user to be given guidance to recognize which key of the remote control unit is to be used on the setting screen for optimally setting parameters for the AV apparatus. It is, therefore, possible to facilitate the setting operation.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0017]     An embodiment of the present invention will be described hereinafter with reference to the drawings. As shown in the block diagram of  FIG. 1 , an AV apparatus according to the embodiment of the present invention includes a display monitor  400 , a remote control unit  200 , a video signal processing integrated circuit (Chroma IC)  300  for displaying a setting screen, on which a user can make various settings of the AV apparatus, on the display monitor  400 , and a microcomputer  100  including an ON screen display (“OSD”) display section  103  that controls the video signal processing IC  300  to display the setting screen. The microcomputer  100  also includes a discrimination section  101  that discriminates a signal from the remote control unit  200 , and an indication section  102  that controls the OSD display section  103 , whereby the user can make the settings of the AV apparatus on the setting screen using the remote control unit  200 .  
         [0018]     The remote control unit  200  includes a keypad  210  having a key layout shown in  FIG. 2 . On the key layout of this keypad  210 , a power button  4 , an external connection button  5 , a display button  6 , a sleep key  7 , a mute key  8 , move up, down, right, and left keys  13 ,  10 ,  9 , and  12 , a menu key  14 , and an Enter key  11  are arranged.  
         [0019]     The microcomputer  100  shown in  FIG. 1  is programmed to display a setting screen  410  ( 410 A,  410 B, or  410 C) on which the user performs a setting operation for this AV apparatus onto a display monitor  400  using the remote control unit  200 . On this setting screen  410  ( 410 A,  410 B, or  410 C), a choice display section  412  ( 412 A,  412 B, or  412 C) that displays choices for the settings, a guide section  413  ( 413 A,  413 B, or  413 C) that gives the user guidance in how to make choices, and a keypad pattern  411  ( 411 A,  411 B, or  411 C) of the remote control unit  200  are displayed. In  FIG. 3 , this setting screen  410  is displayed as a child screen arranged in a partial portion of the display monitor  400 . Needless to say, the setting screen  410  can be displayed entirely on the display monitor  400 .  
         [0020]     When the user depresses the menu key  14  of the remote control unit  200  at a certain time, the setting screen  410  shown in  FIG. 3 , for example, is displayed. On the setting screen  410 , the user can select a setting type in the choice display section  412 . The guidance for the selection is displayed in the guide section  413 . Namely, after moving a cursor onto a desired setting type by the move up key  13  and the move down key  10 , the user depresses the Enter key  11  to recognize that the setting type is selected. At this time, in the keypad pattern  411  of the remote control unit  200  displayed in parallel with displays of these sections  412  and  413 , keys that are available for the user&#39;s selection according to the guidance displayed in the guide section  413  are selectively displayed while being marked and highlighted. In FIGS.  3  to  6 , the available keys are displayed in black. Namely, the available keys are displayed in a color different from a color of unavailable keys or at a brightness which enables the user to discriminate the available keys from the unavailable keys. Alternatively, only the available keys may be flashing the light on and off.  
         [0021]     When the user then depresses the move down key  10  of the remote control unit  200  once, the setting screen  410 A for selecting a “voice setting” shown in  FIG. 4  is displayed. In the keypad pattern  411 A on this setting screen  410 A, the move up key  13  which is not marked in the keypad pattern  411  of the previous setting screen  410  is marked. This is because this setting screen  410 A enables the user to move the cursor onto a “video setting” displayed on an upper position and to select the “video setting” using the move up key  13 .  
         [0022]     When the user then depresses the Enter key  11 , the setting screen  410 B for the “voice setting” shown in  FIG. 5  is displayed. On this setting screen  410 B, the user can make settings such as treble, bass, balance, on or off settings of sound in the choice display section  412 B. Remote control unit usage guidance in making these settings is displayed in the guide section  413 B, and available keys of the remote control unit  200  are displayed while being marked in the keypad pattern  411 B. On the setting screen  410 B on which the treble setting is selected, a volume of the treble can be selected by the move left and move right keys  12  and  9 .  
         [0023]     When the user then depresses the move down key  10  and selects the bass setting, the setting screen  410 C is displayed. On this setting screen  410 C, voice setting items are displayed in the choice display section  412 C, remote control unit keys available for making the settings are guided by characters in the guide section  413 C, and the remote control unit keys available on the setting screen  410 C are displayed while being marked in the keypad pattern  411 C.  
         [0024]     On each of these displayed setting screens according to the embodiment of the present invention, the keypad pattern  411  ( 411 A,  411 B, or  411 C) of the remote control unit  200 , in which available remote control unit keys are displayed while being marked, is displayed. Therefore, the present invention has an industrial adaptability that the AV apparatus facilitating user&#39;s executing the AV apparatus setting operation can be obtained.
