[0020]
Next, an example of screen switching according to the present invention will be described with reference to FIGS. For example, in FIG. 3A, consider a case where the screen jumps from the screen of page 0.1 to the screen of page 0.4. In each screen, the cursor is always at the top button. Conventionally, in the screen of page 0.1, first, the cursor button 80 of the remote controller 70 is operated to move the cursor to the "next" button 13, and when the enter button 81 is pressed, the screen of page 0.2 is displayed. Since the switching is performed, the operation of operating the cursor button 80 again on the screen of page 0.2, moving the cursor to the “next” button 17 and pressing the determination button 81 is repeated, and the screen of page 0.4 is repeated. To reach. On the other hand, in the case of the present invention, for example, the skip button 77 in the feed direction of the remote controller 70 is pressed while the screen of the page 0.1 is displayed. Then, the screen immediately switches to page 0.2. Then, when the skip button 77 is pressed again while the screen of the page 0.2 is displayed, the screen immediately switches to the page 0.3. Then, when the skip button 77 is pressed again while the screen of the page 0.3 is displayed, the screen is immediately switched to the page 0.4. Thus, in the case of the present invention, it is possible to jump from page 0.1 to page 0.4 only by pressing the skip button 77 three times, and it is not necessary to operate the cursor button 80 many times as in the related art.
[0021]
In the above example, the screen is skipped. However, when returning to the previous screen, the same operation is performed by operating, for example, the skip button 78 in the return direction. That is, when returning from page 0.4 to page 0.1, the skip button 78 in the return direction of the remote controller 70 is pressed while the screen of page 0.4 is displayed. Then, the screen returns to page 0.3. Then, when the skip button 78 is pressed again while the screen of the page 0.3 is displayed, the screen returns to the page 0.2. Further, when the skip button 78 is pressed again while the page 0.2 is displayed, the screen returns to the page 0.1. Thus, it is possible to return from page 0.4 to page 0.1 only by pressing the return direction skip button 78 three times.
[0022]
Further, in FIG. 4A, for example, when jumping from the page 1.1 to the screen of the page 1.4, the skip button 77 in the feed direction of the remote controller 70 is pressed while the screen of the page 1.1 is displayed. Push. Then, the screen jumps to page 1.3. Then, when the skip button 77 is pressed again while the page 1.3 is displayed, the screen is immediately switched to the page 1.4. In this way, it is possible to jump from page 1.1 to page 1.4 only by pressing the skip button 77 in the feed direction twice. When returning from page 1.4 to page 1.1, the user presses the return direction skip button 78 of the remote controller 70 while the screen of page 1.4 is displayed. Then, the screen returns to page 1.3. When the skip button 78 is pressed again while the screen of the page 1.3 is displayed, the screen jumps to the page 1.1 and returns. Thus, it is possible to return from page 1.4 to page 1.1 only by pressing the return direction skip button 78 twice.
[0023]
As described in detail later, the operation described above can be performed by selecting a button having a command for proceeding to a previous screen (a “next” button or a “main part” button) among buttons on each page as a “advance button”. When a specific button (here, the skip button 77) of the remote controller 70 is operated on the screen having the “advance button”, the command of the “advance button” is executed, and the screen corresponding to the command is displayed. To fly. Further, among the buttons on each page, a button having a command to return to the previous screen (a “return” button or a “menu” button) is assigned as a “return button”. When the button (in this case, the skip button 78) is operated, the command of the "return button" is executed, and the screen returns to the screen corresponding to the command.
[0024]
Next, the screen switching operation in the present invention will be described in more detail with reference to a flowchart. FIG. 5 shows a process when the menu button 72 of the remote controller 70 is pressed. When the menu button 72 is pressed, the position information (domain, PGC number, PG number, Cell number) of the menu being reproduced is initialized (step S1). Subsequently, information for reproducing (displaying) the menu, that is, screen display data recorded in the VOBU is read from the optical disk 51 (step S2). Next, a return button determination process is performed (step S3), and subsequently, an advance button determination process is performed (step S4). Through these processes, the buttons on the menu screen are assigned to the return button and the advance button. Details of this determination processing will be described with reference to FIGS. After the buttons are assigned, the menu is reproduced and displayed, and the position information of the menu is stored (step S5). Through a series of these processes, for example, the menu of page 0.1 in FIG. 3A is displayed on the screen, and the screen enters a standby state.
[0025]
FIG. 6 is a flowchart showing a procedure for assigning a return button. First, it is determined whether or not there is a button having a command for returning to the previous screen in the current menu screen (step S11). If there is a button having a command to return to the previous screen (step S11: YES), the button is assigned to a return button (step S12). On the other hand, if there is no button having a command to return to the previous screen (step S11: NO), 0 is assigned as the number of the return button (step S13). For example, since there is no button having a command to return to the previous screen on page 0.1, the button number of the return button is set to 0. Also, since the page 0.2 has a "return" button 16 as a button having a command to return to the previous screen, this is assigned as a return button. Here, the button on the screen is given a button number in the page in advance. For example, in page 0.2, the title button 14 is the button number 1, the title button 15 is the button number 2, and the "return" button 16 is the button number. 3. The button number 4 is assigned to the “next” button 17. The same applies to other pages. As a result, if there is no button that has a command to return to the previous screen, the button number is set to 0. If there is a button that has a command to return to the previous screen, the button number of that button is set to the button number of the return button. (In the above example, the button number 3 of the “return” button 16 is the button number of the return button.)
[0026]
FIG. 7 is a flowchart showing a procedure for assigning the advance button. First, it is determined whether or not there is a button having a command for proceeding to the previous screen in the current menu screen (step S21). If there is no button having a command for proceeding to the previous screen (step S21: NO), 0 is assigned to the button number of the proceed button and the process ends (step S36). On the other hand, if there is a button having a command for proceeding to the previous screen (step S21: YES), it is determined whether or not there is one button (step S22). When there is only one button having a command for proceeding to the previous screen (step S22: YES), the button is assigned to the advance button (step S23). For example, since the page 0.1 has a “next” button 13 as a button having a command for proceeding to the previous screen, the button number of the “next” button 13 (for example, number 3) is assigned as the number of the advance button. .
[0027]
On the other hand, when there are a plurality of buttons having a command for proceeding to the previous screen (step S22: NO), next, a cell movement command, that is, the above-mentioned “Link Next C” or “Link Prev C” is included in the buttons. It is determined whether or not there is something to hold (step S24). If there is a button having the cell move command (step S24: YES), it is further determined whether or not the button is one (step S25). If there is one button (step S25: YES), the button is assigned to the advance button (step S26). When there are a plurality of buttons (step S25: NO), the process proceeds to step S32 described later.
[0028]
If there is no button having the cell move command in step S24 (step S24: NO), it is next determined whether there is a program move command, that is, a button having the above-mentioned “Link PG” or the like (step S27). ). If there is a button having the program move command (step S27: YES), it is further determined whether or not the button is one (step S28). If there is one button (step S28: YES), the button is assigned to the advance button (step S29). When there are a plurality of buttons (step S28: NO), the process proceeds to step S32 described later. For example, on page 1.1, the language setting button 31 and the main part button 32 are provided as buttons having a program movement command, so the determination in step S28 is NO, and the process proceeds to step S32.
[0029]
If there is no button having the program move command in step S27 (step S27: NO), the button command is a program chain move command (for example, “Link PGC”), and whether or not there is one button having this command Is determined (step S30). If there is one button (step S30: YES), the button is assigned to the advance button (step S31). When there are a plurality of buttons (step S30: NO), the process proceeds to step S32 described later.
[0030]
In step S32, when there are a plurality of buttons, the destination menu information corresponding to each button is read ahead, and the number of buttons to which the title or chapter playback command is assigned in the menu is determined by setting the language or the like. Calculate how many setting commands to perform are greater than the number of assigned buttons. Then, it is determined whether or not the largest value is one in the calculation result (step S33). If there is one (step S33: YES), the button is assigned to the advance button (step S34). For example, on page 1.1, page 1.2, to which the language setting button 31 is moved, has two buttons 34 and 35 to which setting commands are assigned, but a title or chapter playback command is assigned. There is no button. On the other hand, on page 1.3, which is the destination of the main part button 32, there is no button to which a setting command is assigned, and there are two buttons 37, 38 to which a chapter playback command is assigned. Therefore, in step S34, the main part button 32 is assigned as an advance button. On the other hand, if the largest value is not one in the calculation result, that is, if there are a plurality of the same values (step S33: NO), the button linking the current screen to the closest screen is assigned to the advance button ( Step S35).
[0031]
FIG. 8 is a flowchart showing the procedure of button processing during menu display. When the button on the remote controller 70 is pressed in the standby state after the processing in FIG. 5 is completed, first, it is determined whether or not the pressed button is a skip button 78 (hereinafter, referred to as a “return button”) in the return direction. (Step S41). If the pressed button is the return button 78 (step S41: YES), it is determined whether the number of the return button on the menu screen is other than 0 (step S42). If the number of the return button is 0 (step S42: NO), the process is terminated because no return button is assigned to the screen.
[0032]
On the other hand, if the number of the return button is other than 0 (step S42: YES), since the return button is assigned to the screen, the highlight is moved to the button corresponding to the return button number on the screen. Thereafter (step S43), the command of the button is executed, and information for reproducing the menu is read (step S49). After executing this command, steps S50 and S51 are executed in order to assign a return button and an advance button on the new menu screen at the destination. The procedures of steps S50 and S51 are the same as the procedures shown in FIGS. 6 and 7, respectively. After the return button and the advance button are assigned in steps S50 and S51, the menu at the destination is reproduced and displayed, the position information of the menu is stored (step S52), and the process returns to step S41.
[0033]
In step S41, if the pressed button is not the return button 78 (step S41: NO), it is next determined whether or not the button is a skip button 77 in the feed direction (hereinafter, referred to as a "feed button"). (Step S44). If the pressed button is the forward button 77 (step S44: YES), it is determined whether the number of the advance button on the menu screen is other than 0 (step S45). If the number of the advance button is 0 (step S45: NO), the process ends because no advance button is assigned to the screen.
[0034]
On the other hand, if the number of the advance button is not 0 (step S45: YES), since the advance button is assigned to the screen, the highlight is moved to the button corresponding to the advance button number on the screen. Thereafter (step S46), the command of that button is executed, and information for reproducing the menu is read (step S49). After executing this command, steps S50 and S51 are executed in order to assign a return button and an advance button on the new menu screen at the destination. After the return button and the advance button are assigned, the menu at the destination is reproduced and displayed, the position information of the menu is stored (step S52), and the process returns to step S41.
[0035]
In step S44, if the pressed button is not the feed button 77 (step S44: NO), it is next determined whether or not the button is the determination button 81 (step S47). If it is the determination button 81 (step S47: NO), it is next determined whether or not the screen jumps to another menu by the determination of the determination button 81 (step S48). When jumping to another menu (step S48: YES), the process proceeds to step S49, and the above-described steps S49 to S52 are executed. For example, when the language setting button 31 or the main part button 32 is selected on the screen of the page 1.1 and the enter button 81 is pressed, these buttons are for jumping to another menu. Is YES, steps S49 to S52 are executed, and a new screen is displayed. On the other hand, when the screen does not jump to another menu due to the determination of the determination button 81, for example, when the end button 33 is selected and the determination button 81 is pressed on the screen of page 1.1 (step S48: NO), the processing ends. The command “Exit” of the button 33 is executed, and the process ends (step S53).
[0036]
In step S47, if the pressed button is not the determination button 81 (step S47: NO), a process corresponding to the button is performed and the process ends (step S54). For example, when the cursor button 80 is pressed, a process of moving the cursor on the screen is performed.
[0037]
FIG. 9 is a list of buttons of each page assigned to the return button and the advance button according to the flowcharts of FIGS. 6 and 7.
[0038]
As described above, according to the embodiment, of the buttons on each page, a button having a command to go to the previous screen is assigned to a forward button, and a button having a command to return to the previous screen is assigned to a return button. By simply operating the feed button 77 or the return button 78 of the remote controller 70, the screen can be quickly sent or returned, and the cursor is moved with the cursor button and then the enter button is pressed as in the conventional case. This procedure becomes unnecessary. For this reason, the operability is greatly improved, and the user becomes very easy to use.
[0039]
In the above-described embodiment, an example in which the skip buttons 77 and 78 are used as the feed button and the return button of the remote controller 70 has been described. However, the feed button and the return button are If it is, it is not limited to only the skip button. For example, the fast forward button 75 in FIG. 2 may be a forward button, and the fast reverse button 76 may be a reverse button. Alternatively, an up / down key of the volume button 82 or an up / down key of the music selection button 83 may be used as a forward button and a return button.
[0040]
Further, in the above embodiment, the case where the operation is performed using the remote controller 70 as the operation unit has been described as an example. However, the present invention is also applicable to the case where the operation is performed using the operation unit 59 (FIG. And can be similarly applied.
