Description

  The present invention relates to a technique that enables a user to intuitively understand a response of a controlled device caused by an operation of a control device when the user gets lost in the operation.

  In recent years, many program playback devices such as televisions have abundant functions such as a function for browsing by connecting to the Internet and a function for selecting and playing back a program to be viewed using a program guide obtained from a broadcast wave or the like. ing. The remote controller used for this operation has a large number of keys, and the number of buttons (GUI buttons) used for the GUI displayed on the display screen as a user interface is also increased. It's getting complicated.

  In order to cope with this complicated operation, a technique for guiding a user is known (see, for example, Patent Documents 1 and 2).

  In Patent Document 1, when a user touches a key on the remote controller, the function corresponding to the key is explained by voice from the remote controller, or the explanation of the function corresponding to the key is displayed on the LCD display provided in the remote controller. The user can understand the operation by reading the explanation. In addition, what the user wants to do is guided.

In Patent Document 2, a provisional selection of a GUI button is performed by the first input, and what is selected is shown to the user by voice or screen display, and the selection is confirmed by the second input.

  However, in the technique disclosed in Patent Document 1, it is necessary to touch a key on the remote control and listen to a guide voice about the function of the key from the remote control or read a character expressed in the GUI on the remote control. The effect of pressing the key cannot be immediately and intuitively understood by the user.

  Similarly, in Patent Document 2, the user selects a plurality of selection items expressed in the GUI on the monitor screen once, and then listens to a guide voice explaining the item or displays the selection items on the GUI. It is not possible for the user to immediately and intuitively understand it.

  Therefore, the present invention solves the above-described problem, and when the user operates the program playback device with the remote controller, when the user presses the key about half (half press), the key is completely set. The program playback device displays a screen (next screen) that transitions when confirmed by being pressed (fully pressed). This makes it possible to intuitively understand the effect when the user presses the key, confirm the next screen generated by the key operation, and if the next screen is as expected, the program can continue the operation as it is An object is to provide a playback device.

  In order to achieve the above object, a program playback apparatus of the present invention comprises a receiving means for receiving a command from a remote controller and a screen control means for changing a display screen in accordance with the command. When the screen control means receives the first command from the remote controller, a next screen presenting means for presenting a screen to be displayed when transitioning to the next state; and the screen control means from the remote controller When the second command is received, a next screen transition means for transitioning to the next state and displaying the screen is configured.

  With such a configuration, when a certain remote control key is half-pressed, the next screen displayed when the key is fully pressed can be presented to the user, so the user can see what the next screen will look like. Can be intuitively understood.

  As described above, according to the program playback device of the present invention, even when there are a large number of remote control keys and GUI buttons, the next screen is expressed by pressing a remote control key halfway. The user can intuitively understand the confirmation of the effect produced by pressing the key without having to listen to or read the explanation of the guide. By checking the next screen, if the next screen is the screen as expected, you can continue to operate by pressing the remote control key fully, eliminating the resistance that it is difficult for the user to operate the program playback device, The user can easily control the program playback device.

  The program reproduction apparatus of the present invention is a program reproduction apparatus comprising a receiving means for receiving a command from a remote control and a screen control means for changing a display screen in accordance with the command, wherein the screen control means is provided from the remote control. When the first command is received, next screen presenting means for presenting a screen to be displayed when transitioning to the next state, and when the screen control means receives the second command from the remote control Comprises a next screen transition means for transitioning to the next state and displaying the screen.

  With such a configuration, when a certain remote control key is half-pressed, the next screen displayed when the key is fully pressed can be presented to the user, so the user can see what the next screen will look like. Can be intuitively understood.

  Further, in the program playback device of the present invention, the next screen presenting means presents a screen to be displayed when transitioning to the next state while continuing to receive the first command from the remote controller. You may comprise as follows.

  With such a configuration, the user can check the next screen as long as the user keeps pressing halfway, so that the user can operate after carefully checking the next screen.

  Further, in the program playback device of the present invention, the next screen presenting means is configured to present the screen displayed when transitioning to the next state, reduced to a part of the currently displayed screen. It doesn't matter.

  With this configuration, the user can check the next screen when operating the remote control at the same time as the currently displayed screen, so that the next screen can be displayed without losing an overview of the information on the currently displayed screen. Can be confirmed.

(Embodiment)
Embodiments of the present invention will be described below with reference to the drawings.

  The program playback apparatus according to the embodiment of the present invention is equipped with a browser capable of browsing WEB pages and the like through the Internet. The remote controller used for operating the program reproducing apparatus will be described by taking several direction movement keys and a “decision” key as a key for confirming the operation as an example.

  When browsing a WEB page or the like using the browser, it is possible to perform full-press and half-press operations on the determination key of the remote controller of the program playback device, and a command corresponding to each is transmitted to the program playback device. The A focus button can be moved by operating a direction key of the remote controller, and a GUI button displayed on the screen can be selected. At this time, when the program playback device receives a half-press command of the enter key of the remote control, it presents the next transition screen (next screen), which is the same as that confirmed with the enter key. In this state, the processing by the enter key is not yet confirmed. Thereafter, when a command for fully pressing the enter key is received, the transition to the next screen is confirmed and the processing is performed.

  In addition, when the next screen is presented with a half-press command, if the half-press command is canceled (for example, the finger is released from the OK key on the remote control), the original screen before the next screen is presented ( Return to the original screen. The half-pressed state and the fully-pressed state of the keys on the remote controller can be realized by using, for example, a two-stage switch.

  FIG. 1 is a diagram showing a configuration of a program playback device in an embodiment of the present invention, FIG. 2 is a flowchart showing a process flow of the program playback device in an embodiment of the present invention, and FIG. 3 is a diagram showing a GUI button display screen. 4 is a diagram showing a presentation screen of the next screen in the embodiment of the present invention, and FIG. 5 is a diagram showing a presentation screen of another next screen in the embodiment of the present invention.

  A program playback apparatus according to an embodiment of the present invention presents a receiving unit 100 that receives a command from a remote controller (not shown), a screen control unit 101 that controls a screen in accordance with a command from the remote controller, and a next screen on the display screen. Next screen presenting means 102 and next screen transition means 103 for transitioning the original screen to the next screen are configured.

  The receiving means 100 receives a command from the remote controller.

  The user browses a WEB page or the like through the Internet using a browser installed in the program playback device, and the display screen displays “link A” which is a GUI button on the browser as shown in FIG. The link button 302 displayed and the link button 303 displayed as “link B” are displayed.

  The user selects a button on the browser by moving the focus using the remote controller. By moving the focus to the link button 302 by operating the remote controller and pressing the enter key on the remote controller halfway, the enter key half-press command is transmitted from the remote control, and the receiving means 100 of the program playback apparatus receives the half-press command. To do.

  At this time, as shown in FIG. 4, the next screen when the link button 302 is selected is displayed. As a result, the user can know in advance what screen will be displayed when the link button 302 is selected. Further, as shown in FIG. 5, a reduced next screen 501 obtained by reducing the next screen when the link button 302 is selected may be displayed over the original screen 301.

  When the user stops the half-pressing state of the enter key while the next screen is displayed as shown in FIGS. 4 and 5, the transmission of the half-press command of the enter key from the remote control is stopped. Since the receiving means 100 does not receive the half-press command, the original screen 301 shown in FIG. 3 is displayed.

  When the next screen shown in FIG. 4 or 5 is displayed, that is, when the user changes the enter key from the half-pressed state to the fully-pressed state, the enter key full-press command is transmitted and received from the remote control. Means 100 receives the full press command. The next screen is presented by acquiring the html file of the URL from the URL information of the GUI button on which the browser has the focus, and rendering it with the browser. At that time, the html file of the original screen is stored in the program playback device.

  Hereinafter, the processing flow of the program reproducing apparatus in the embodiment of the present invention shown in FIG. 2 will be described.

  The screen control means 101 determines whether or not the remote control command received by the receiving means 100 is a half-press command (S21). If it is determined that the received remote control command is not a half-press command, the next remote control command is determined. This process is repeated until a half-press command is received. If a half-press command is received, next screen presentation start processing (S22) is performed.

  The next screen presenting means 102 causes the program playback device to start presenting the next screen based on information from the screen control means 101 that the received remote control command is a half-press command (S22).

  The next screen presenting means 102 determines whether or not the screen control means 101 has received the full press command after starting the next screen presentation (S23). It is determined whether command reception is continued (S23, S24). During the processes of S23 to S24, presentation of the next screen is continued.

  When the next screen presenting means 102 determines that the screen control means 101 has received the full-press command after starting the next screen presentation, the next screen transition means 103 changes the displayed screen to the next screen, A processing instruction for the screen is received (S26).

  When the next screen presenting means 102 determines that the screen control means 101 has not received the full press command after starting the next screen presentation, and determines that the half press command has not been received, the next screen presenting means 102 Is stopped (S25), and the program playback device displays the original screen before the next screen is displayed. The original screen is displayed by redrawing the html file stored in the browser with the browser. For example, the display of the next screen in FIG. 5 returns to the original GUI button selection display in FIG. 4, and the user releases the half-pressed state of the enter key after intuitively understanding the next screen. Thus, it is possible to easily return to the original screen, and the selection operation can be continuously performed in the GUI button selection display of FIG.

  That is, the next screen becomes the original screen in the next operation without changing as it is, and the user can grasp the next screen and perform the operation immediately after determination.

  In the present embodiment, when the next screen is presented, the next screen is displayed on the entire screen as shown in FIG. 4, but the next screen is reduced as shown in FIG. 5 on the original screen. The present invention can be realized even if it is partially displayed. In this case, when the next screen presentation is canceled in S25, the reduced next screen disappears from the screen, and the screen returns to the original screen as shown in FIG. Also, when the original screen is changed to the next screen in S26, the next screen reduced from the screen disappears and the original screen on the screen is switched to the next screen. That is, on the screen, the display of FIG. 5 is switched to the display of FIG.

  In the present embodiment, the input state of the remote control key is divided into half-press or full-press when the command is transmitted from the remote control. However, this is an example of the method for dividing the input state of the remote control key according to the present invention. is there. In addition, a distinction is made between a state in which the user's finger is in contact with the remote control key and a state in which the remote control key is pressed, a distinction according to a state in which the remote control key is pressed once, a state in which it is pressed twice, etc. As long as the two types of states designated by the user using the remote control can be recognized as two types of commands on the remote control side or the program playback device side, other input methods may be used.

  In the present embodiment, the GUI button on the browser has been described as an example. However, the browser is an example of a function used in the present invention, and this GUI can be used for other GUI operations such as a selection operation in a GUI menu of a television. The invention can be realized.

  In the present embodiment, the determination key on the remote control is described as an example. However, not only the determination key on the remote control but also other keys such as a movement key and a menu key are half-pressed or fully pressed. It doesn't matter if you do.

  Also, in the present embodiment, when the next screen is presented and the original screen is displayed, the html file of the original screen is stored in the program playback device, and the html file is re-drawn when the original screen is displayed. However, this is an example of the method used for presenting the next screen and displaying the original screen using the present invention. When the original screen is displayed, the image of the browser depicting the original screen is saved in the memory. May be re-drawn from the stored memory, or may be obtained again with respect to the display of the original screen.

  According to the program playback device of the present invention, since the user can intuitively understand the operation performed by displaying the next screen, the program playback device is useful in a program playback device equipped with various GUIs.
