  Here, in the following description, the screen transition pattern is a display order of screens displayed on the video display device 15 from a starting point screen that is a predetermined starting point screen to a predetermined target screen. It shall be shown. Here, in the present embodiment, the starting screen is the screen (Top menu selection screen 31) next to the top screen (Top menu screen 30). In addition, it is desirable that the target screen is a screen on which the user makes a desired input or selection and a screen predetermined for displaying information to the user. In the example shown in FIGS. 5 and 6, the target screens are a manual reservation screen 33, a G code reservation screen 34, a volume setting screen 35, and a Ch registration screen 38.

  The back end unit 19b illustrated in FIG. 4 includes a count unit 19c, a priority order determination unit 19d, a history information update unit 19e, a menu display determination unit 19f, and a divided menu file update unit 19g.

The count unit 19c counts, for each target screen, the number of times the target screen is used by a user's menu operation in a predetermined period.
For example, when the count unit 19c determines that the purpose has been fulfilled according to the purpose for displaying the target screen, the count unit 19c adds “1” to the number of times the target screen has been used. For example, the count unit 19c has a purpose of the target screen when the user inputs execution of processing using the input unit 18 on the target screen or when specific information is displayed on the target screen for a specific period. Judge that it was fulfilled.
On the other hand, when the counting unit 19c determines that the displayed target screen is not used, for example, the user uses the input unit 18 to press a return button (not shown) on the target screen, and so on. When the screen returns to the screen, the target screen on which the return button (not shown) is pressed is not counted as the number of times the target screen is used.
The priority order determination unit 19d determines the usage frequency order of the target screen based on the number of times counted by the counting unit 19c. Then, the priority order determination unit 19b determines the priority order of the screen transition pattern based on the determined usage frequency order.
The history information update unit 19c updates menu screen selection history information 40 (see FIG. 7 or FIG. 9), which will be described later, based on the usage frequency order and the priority order determined by the priority order determination unit 19b.
If the menu display determination unit 19f determines that the screen transition is to be automatically performed based on the user's operation, the menu display determination unit 19f gives the screen transition information indicating the screen transition pattern to the system control unit 19a. Note that the system control unit 19a automatically assigns each screen from the start screen to the target screen to the video display device 15 automatically (without input from the user) based on the given screen transition information. Transition (display) to.
The divided menu file update unit 19g performs a process of updating a divided menu file 50 described later based on menu screen selection history information 40 described later.

FIG. 7 is a schematic diagram of the menu screen selection history information 40 (A).
Here, in FIG. 7 and FIG. 9, the symbols “A, B” in parentheses attached to the symbols “40”, “40a”, and “40b” indicate the contents of the menu screen selection history information that are different every time it is updated. It is intended to indicate that the above is true, and is not attached when it is not necessary to distinguish between them or when generalizing them. The same applies to the following.
The menu screen selection history information 40 is stored in a storage unit configured by at least one of the ROM 2c, the RAM 2d, and the HDD 12. Note that the menu screen selection history information 40 (A) shown in FIG. 7 is in the state when the video information display control device 1 is shipped from the factory.

  The menu screen selection history information 40 includes information indicating a priority order, a usage frequency order, and a screen transition pattern for each major item on the Top menu screen 30. For example, the menu screen selection history information 40 is configured by a table including a priority order column 41, a usage frequency order column 42, and a screen transition column 43 for each major item of the Top menu screen 30. The table 40a is a table of “reservation” item 30a, and the table 40b is a table of “setting” item 30b.

The priority column 41 stores a value indicating the priority of the screen transition pattern stored in the screen transition column 43. The priority column 41 stores an integer value of 1 or more. The smaller the value, the higher the priority. In the present embodiment, there is one screen transition pattern with a priority order of “1” and “2”. All the screen transition patterns other than the priority orders “1” and “2” have the priority order “3”.
The usage frequency ranking column 42 stores a value indicating the usage frequency ranking of the target screen included in the screen transition pattern stored in the screen transition column 43. The usage frequency rank column 42 stores an integer value of 1 or more. The target screen that is used more frequently has a smaller value.
The screen transition field 43 stores information indicating a screen transition pattern when each major item is selected on the Top menu screen 30.
In the table constituting the menu screen selection history information 40, information indicating a screen transition pattern having a higher priority order is stored in an upper record, and information indicating a screen transition pattern moving to a target screen having a higher use frequency order is indicated. , Stored in the upper record.

At the time of factory shipment, the priority order is predetermined by default for each screen transition pattern. For example, in the “reservation” item table 40a (A), the priority order 1 is a screen transition pattern of “Top menu selection screen (reservation) → recording reservation screen → G code reservation screen”. This is based on the assumption that there are many program reservations in the G code. The priority order 2 is a screen transition pattern of “Top menu selection screen (reservation) → recording reservation screen → program guide screen”. Priority order 3 is all screen transition patterns that have not been assigned priority orders 1 and 2, such as a screen transition pattern of “Top menu selection screen (reservation) → recording reservation screen → manual reservation screen”.
In the “setting” item table 40b (A), the priority order 1 is a screen transition pattern of “Top menu selection screen (setting) → Ch scan (residential) screen → Ch scan screen → Ch registration screen”. This is because, in the factory-shipped state, the user of the video information display control device 1 cannot view the program unless the Ch scan is always performed. The priority order 2 is a screen transition pattern of “Top menu selection screen (setting) → notification mail screen”. Priority order 3 is all screen transition patterns that have not been assigned priority orders 1 and 2, such as a screen transition pattern of “Top menu selection screen (setting) → volume setting screen”.

  FIG. 8 is a flowchart showing processing when the user performs a menu operation. This flow is executed every time the user performs a menu operation.

First, the menu display determination unit 19f determines whether or not the user's menu operation follows a screen transition pattern having a high priority in the menu screen selection history information 40 (S001).
For example, the menu display determination unit 19f determines that the screen that first transitions by the user's operation on the Top menu screen 30 is the starting screen of the screen transition pattern with the priority order 1 in any table that configures the menu screen selection history information 40. If yes, it is determined Yes in step S001. In the present embodiment, the menu screen selection history information 40 is formed for each major item that can be selected on the Top menu screen 30, so that the user's operation on the Top menu screen 30 is one of the major items. If the menu display is determined, the menu display determination unit 19f determines Yes in step S001.
If the menu display determination unit 19f determines Yes in step S001, the process proceeds to step S002. If the determination is No in step S001, the menu display determination unit 19f proceeds to the process in step S003.

In step S002, the menu display determination unit 19f provides screen transition information indicating the screen transition pattern determined to be performed in step S001 to the system control unit 19a. The screen transition information includes screens displayed from the start screen to the target screen and the display order of each screen.
The system control unit 19a refers to the given screen transition information, and the screen control object from the origin screen to the target screen and the menu control code for transitioning the screen from the origin screen to the target screen are described in the priority order described later. 1 object group (OJ1 expansion) and common menu control code group (PCO expansion) (see FIG. 13). The system control unit 19a automatically performs screen transition to the target screen by executing the acquired object and menu control code.

  In step S003, when the target screen moved by the user's menu operation is used by the user, the count unit 19c increments (counts up) “1” to the number of times this target screen has been used.

  Next, the priority order determination unit 19d updates the usage frequency order of the screen transition pattern based on the number of times counted in step S003 (S004). The priority order determination unit 19d sets a higher use frequency order for a screen transition pattern that reaches a target screen having a larger number of counted times.

  Next, the priority order determination unit 19d determines the priority order of the screen transition pattern based on the usage frequency order updated in step S004 (S005). The priority order determination unit 19d sets a higher priority order for a screen transition pattern that reaches a target screen having a higher use frequency order.

  Next, the history information update unit 19e reflects the updated use frequency order and the determined priority order in the menu screen selection history information 40 (S006).

  FIG. 9 is a schematic diagram showing menu screen selection history information 40 (B) updated as a result of the user performing menu operations from the menu screen selection history information 40 (A) at the time of factory shipment shown in FIG. .

For example, when the “reservation” item 30a is selected on the Top menu screen 30 (see FIG. 5), the manual reservation screen 33 is used most frequently (the frequency of use is the highest) and the G code reservation screen 34 is used. In the table 40a (B) of the “reservation” item, the priority 1 is “Top menu selection screen (reservation) → recording reservation screen → manual reservation screen”. It becomes a transition pattern. Further, the priority order 2 is a screen transition pattern of “Top menu selection screen (reservation) → recording reservation screen → G code reservation screen”. The priority order 3 is all screen transition patterns other than the priority orders 1 and 2.
When the “setting” item 30b is selected on the Top menu screen 30 (see FIG. 6), the volume setting screen 35 is used most frequently, and the notification mail screen (not shown) is used next. Sometimes, in the table 40 (B) of the “setting” item, the priority order 1 is a screen transition pattern of “Top menu selection screen (setting) → volume setting screen”. The priority order 2 is a screen transition pattern of “Top menu selection screen (setting) → notification mail screen”. The priority order 3 is all screen transition patterns other than the priority orders 1 and 2.

  As described above, when the user performs a menu operation, the menu display determination unit 19f refers to the menu screen selection history information 40, so that the screen displayed on the video display device 15 is the target screen that is frequently used. Can be automatically transitioned to.

Hereinafter, a process in which the system control unit 19a automatically changes the screen to be displayed on the video display device 15 based on the screen transition information presented by the menu display determination unit 19f will be described.
When the user moves the cursor (not shown) to the “reservation” item 30a on the Top menu screen 30 shown in FIG. 5 using the input unit 18, the system control unit 19a displays the “viewing reservation” item 31c and “recording”. The top menu selection screen (reservation) 31A in which the “reservation” item 31d is added to the top menu screen 30 is displayed.
When the Top menu selection screen (reservation) 31A is displayed, the system control unit 19a receives the screen transition information from the menu display determination unit 19f.
Then, the system control unit 19a refers to the presented screen transition information, and acquires a screen object from the start screen to the target screen, and a menu control code for transitioning the screen from the start screen to the target screen. These are the priority 1 compressed object group OJ1 and compressed common menu control code group PCO in the divided menu file 50, which will be described later, and the priority 1 object group (OJ1 expansion) and the common menu control code group (PCO). Obtained from expansion).
Then, when the user places a cursor (not shown) on the “viewing reservation” item 31c using the input unit 18 (when item selection is confirmed), the system control unit 19a acquires By executing the object and the menu control code, the screen transition from the start screen to the target screen can be automatically performed.
At this time, the common menu control code (ActionScript, etc. in the Flash file) group (PCO expansion) is described as shown in FIG. 10, for example. It should be noted that the file storing the menu screen selection history information 40 (B) is stored in the menu History. file.
As described above, the system control unit 19a automatically changes the screen by moving a cursor (not shown) and selecting or determining an item on the screen displayed on the video display device 15. Let
For example, the system control unit 19a sets the “recording reservation” item 31d on the Top menu selection screen (reservation) 31A in accordance with the screen transition pattern that is given priority 1 in the table 40a (B) of the “reservation” item. Cursor movement and determination → Display of recording reservation screen 32 → Cursor movement and determination to “manual reservation” item 32b → display of manual reservation screen 33 automatically.

Similarly, when the user moves the cursor (not shown) to the “setting” item 30 b on the Top menu screen 30 shown in FIG. 6, the “Ch scan” item 31 e and the “volume setting” item 31 f are displayed on the Top menu screen 30. The added Top menu selection screen (setting) 31B is displayed.
When the Top menu selection screen (setting) 31B is displayed, the system control unit 19a receives the screen transition information from the menu display determination unit 19f.
Then, the system control unit 19a refers to the presented screen transition information, and acquires a screen object from the start screen to the target screen, and a menu control code for transitioning the screen from the start screen to the target screen. These are the priority 1 compressed object group OJ1 and compressed common menu control code group PCO in the divided menu file 50, which will be described later, and the priority 1 object group (OJ1 expansion) and the common menu control code group (PCO). Obtained from expansion).
Then, when the user places a cursor (not shown) on the “Ch scan” item 31e using the input unit 18 (when item selection is confirmed), the system control unit 19a By executing the menu control code, it is possible to automatically change the screen from the origin screen to the target screen. The common menu control code group at this time is also described in the same manner as that shown in FIG.
As described above, the system control unit 19a proceeds to the “volume setting” item 31f on the Top menu selection screen (setting) 31B in accordance with the screen transition pattern set to the priority order 1 in the table 40b (B) of the “setting” item. Cursor movement and determination → Volume setting screen 35 is automatically displayed.

  In the example described above, at the time when selection of an item is confirmed on the Top menu screen 30 (for example, when the cursor is placed on the “viewing reservation” item 31c), the system control unit 19a displays the screen transition pattern. Is automatically performed, but is not limited to such timing. For example, the system control unit 19a determines when the screen transition information is acquired (when the Top menu selection screen 31 is displayed) or when a predetermined time elapses after the item is selected (when the Top menu selection screen 31 is displayed). The screen transition pattern may be automatically performed when a predetermined time has elapsed since the display.

FIG. 11 is a flowchart showing processing when the divided menu file update unit 19g updates the divided menu file 50 (see FIG. 12).
The divided menu file update unit 19g updates the divided menu file 50 with reference to the menu screen selection history information 40. When the menu operation is not performed after the update process of the menu screen selection history information 40 is finished according to the flowchart shown in FIG. 8, the divided menu file update unit 19g is, for example, while the user is watching the program. It is desirable to update the split menu file 50 in the background.
Here, it is assumed that the divided menu file update unit 19g updates the divided menu file 50 with reference to the menu screen selection history information 40 (B). Further, it is assumed that the divided menu file 50 (old) before update is expanded in the RAM 2d. In the description here, the characters “old” and “new” in parentheses attached to the reference numeral “50” are for distinguishing between information before update and information after update. It is not added when it is not necessary to distinguish or when generalized.

  The divided menu file update unit 19g displays unextracted items among large items such as “reservation” item 30a and “setting” item 30b that can be selected on the Top menu screen 30 (see FIG. 5 or FIG. 6). One is extracted (S100).

  Next, the divided menu file update unit 19g expands the screen object included in the screen transition pattern with the priority order 1 in the table corresponding to the item extracted in step S100 in the menu screen selection history information 40 (B) in the RAM 2d. The divided menu file 50 (old) is checked (S101). For example, when the “reservation” item 30a is extracted in step S100, the divided menu file update unit 19g refers to the menu screen selection history information 40 (B), and displays the Top menu screen, the recording reservation screen, and the manual reservation. Check screen objects.

  Next, the divided menu file update unit 19g converts the screen object included in the screen transition pattern of the priority order 2 in the table corresponding to the item extracted in step S100 into the divided menu file 50 (old) expanded in the RAM 2d. Check (S102). At this time, the divided menu file update unit 19g does not check the objects already checked in step S101. For example, when the “reservation” item 30a is extracted in step S100, the divided menu file update unit 19g does not check the objects on the Top menu screen and the recording reservation screen, but only the objects on the G code reservation screen. To check.

  Next, the divided menu file update unit 19g converts the screen object included in the screen transition pattern of the priority order 3 in the table corresponding to the item extracted in step S100 into the divided menu file 50 (old) expanded in the RAM 2d. (S103). At this time, the divided menu file update unit 19g does not check the objects that have already been checked in step S101 and step S102. For example, when the “reservation” item 30a is extracted in step S100, the divided menu file update unit 19g does not check the objects on the Top menu screen, the recording reservation screen, the manual reservation screen, and the G code reservation screen. Check all other screen objects.

  Then, the divided menu file update unit 19g determines whether or not all items included in the large items that can be selected are extracted on the Top menu screen 30 (S104). If not all items have been extracted (No in step S104), the process returns to step S100. If all items have been extracted (Yes in step S104), the process proceeds to step S105.

In step S105, the divided menu file update unit 19g collects the objects checked in the priorities 1 to 3 from the divided menu file developed in the RAM 2d for each of the priorities 1 to 3 as an object group. The object groups are respectively compressed to generate the respective compressed object groups having the priority orders 1 to 3.
For example, the divided menu file update unit 19g generates a compressed object group of priority 1 by compressing an object group in which objects checked in priority 1 (step S101) are collected. Also, the divided menu file update unit 19g generates a compressed object group of priority 2 by compressing the object group in which the objects checked in priority 2 (step S102) are collected. Further, the divided menu file update unit 19g generates a compressed object group of priority 3 by compressing the object group in which the objects checked in the priority 3 (step S103) are collected.

  Next, the divided menu file update unit 19g generates a fixed-length header (S106). This fixed-length header includes the addresses of the compressed object groups with priority levels 1 to 3 in the updated divided menu file 50 (new) and the expanded size when the compressed object groups with priority levels 1 to 3 are expanded in the RAM 2d. Including.

The divided menu file update unit 19g generates a compressed common menu control code group obtained by compressing the common menu control code group developed in the RAM 2d. Then, the divided menu file updating unit 19g adds the address of the compressed common menu control code group in the divided menu file 50 (New) and the expanded size when the compressed common menu control code group is expanded in the RAM 2d to the header. To do.
Then, the divided menu file update unit 19g generates the updated divided menu file 50 (new) using the header generated as described above, the compressed object group having the priority order 1 to 3 and the compressed common menu control code group.

FIG. 12 is a schematic diagram showing the configuration of the divided menu file 50. As shown, the split menu file 50 includes a header FH, a priority 1 compressed object group OJ1, a priority 2 compressed object group OJ2, a priority 3 compressed object group OJ3, and a compression common menu control code. A group PCO. The divided menu file 50 is all compressed except for the header FH.
Here, it is assumed that the common menu control code group includes a menu control code describing a process necessary for the system control unit 19a to transition the screen from the origin screen to the target screen for each screen transition pattern.

  The divided menu file update unit 19g deletes the divided menu file 50 (old) already stored in the ROM 2c, and stores the updated divided menu file 50 (new) generated as described above in the ROM 2c.

  Here, the divided menu file update unit 19g may update the divided menu file 50 when the menu screen selection history information 40 is updated according to the flowchart shown in FIG. The split menu file 50 may be updated only when there is a change in the priority order in the screen selection history information 40.

  FIG. 13 is a schematic diagram showing processing when the divided menu file 50 stored in the ROM 2c is expanded in the RAM 2d. FIG. 13 shows processing when the compressed object group OJ1 with priority 1 in the divided menu file 50 is expanded in the RAM 2d, and then the compressed object group OJ2 with priority 2 is expanded in the RAM 2d.

  The divided menu file 50 is initially stored in the ROM 2c. Reference numeral 50a denotes a start address of an area where the divided menu file 50 is stored in the ROM 2c. Reference numeral 50b denotes an end address of an area where the divided menu file 50 is stored in the ROM 2c. Reference numeral 51a denotes a start address when the compressed object groups OJ1, OJ2, and OJ3 having the priorities 1 to 3 included in the divided menu file 50 are expanded in the RAM 2d after the divided menu file 50 is copied to the RAM 2d. . Reference numeral 51b denotes an end address when the compressed object groups OJ1, OJ2, and OJ3 having the priority levels 1 to 3 included in the divided menu file 50 are expanded in the RAM 2d after the divided menu file 50 is copied to the RAM 2d. Since the header FH is not compressed, it is not expanded in the RAM 2d. Further, since the compression common menu control code group PCO is not an object constituting the screen, it is not expanded in the area from the start address 51a to the end address 51b.

The system control unit 19a realized by the CPU 2b executing the DTV / netTV program uses the divided menu file 50 as follows.
First, the system control unit 19a copies the header FH of the divided menu file 50 stored in the ROM 2c to a predetermined address in the RAM 2d.
Next, the system control unit 19a refers to the address of the compressed object group OJ1 with priority 1 and the address of the compressed common menu control code group PCO included in the header FH. Then, the system control unit 19a reads the priority-ordered compressed object group OJ1 and the compressed common menu control code group PCO from the divided menu file 50 stored in the ROM 2c based on the referenced address, and stores the predetermined address in the RAM 2d. To copy.
Next, the system control unit 19a expands the compressed object group OJ1 and the compressed common menu control code group PCO having the priority order 1 to predetermined addresses in the RAM 2d. These are programs that can be executed by being expanded in the RAM 2d. Here, when the system control unit 19a displays the priority level 1 screen, the GUI from the priority level 1 object group (OJ1 expansion) and common menu control code group (PCO expansion) programs expanded in the RAM 2d. Start up.
Note that the address at which the compressed object group OJ1 with priority 1 is expanded in the RAM 2d is the start address 51a. The address for expanding the compression common menu control code group PCO into the RAM 2d is the end address 51b. The system control unit 19a can obtain the end address 51b by adding the expanded sizes of the compressed object groups OJ1, OJ2, and OJ3 of the priority orders 1 to 3 included in the header FH to the start address 51a.

  The system control unit 19a expands the priority-ordered compressed object group OJ1 and the compressed common menu control code group PCO in the RAM 2d when the user starts a menu operation (before). In response to the menu operation by, the GUI can be immediately started from these programs. For example, it is preferable that the system control unit 19a expands the compressed object group OJ1 and the compressed common menu control code group PCO having the priority 1 in the RAM 2d when the video information display control device 1 is activated.

Next, when the user of the video information display control device 1 uses the input unit 18 to perform an operation to display a screen that is not included in the screen transition pattern of priority order 1 but is included in the screen transition pattern of priority order 2 The system control unit 19a acquires the address in the divided menu file 50 of the compressed object group OJ2 having the priority 2 from the header FH copied to the RAM 2d. Then, the system control unit 19a refers to the acquired address and copies the compressed object group OJ2 having the priority order 2 stored in the ROM 2c to a predetermined address in the RAM 2d.
Next, the system control unit 19a expands the compressed object group OJ2 of priority 2 to a predetermined address in the RAM 2d. The compressed object group OJ2 having the priority order 2 becomes a program that can be executed by being expanded in the RAM 2d. Here, when the system control unit 19a displays the screen of the priority order 2, the GUI from the object group (OJ2 development) and the common menu control code group (PCO development) of the priority order 2 developed in the RAM 2d. Start up.

  Note that the system control unit 19a may refer to the menu screen selection history information 40 to determine in which priority order the screen transition pattern includes a screen that changes based on a user operation.

  As described above, in the first embodiment, when a user selects a large item on the Top menu screen 30, a frequently used screen is automatically displayed according to a screen transition pattern having a high priority in the menu screen selection history information 40. Will be displayed. For this reason, the operability of the GUI by the user is greatly improved. The priority order of the screen transition pattern is updated so that a frequently used screen has a high priority order when the user repeatedly performs menu operations. For this reason, when a user repeats menu operations, a screen having a higher use frequency of the user is automatically displayed.

  In the first embodiment, the divided menu file update unit 19g generates a divided menu file 50 including a compressed object group obtained by compressing the objects of each priority order based on the menu screen selection history information 40. Then, when starting the menu operation, the system control unit 19a may copy the compressed object group OJ1 having the priority order 1 including the Top menu screen to the RAM 2d and expand it. Therefore, the video information display control device 1 according to the first embodiment can start the menu screen at a higher speed than when the device expands all screen objects on the RAM.

  Further, the system control unit 19a may copy a compressed object group having a priority order other than the priority order 1 in the divided menu file 50 to the RAM 2d and expand it when required by a user operation. For this reason, the system control unit 19a does not need to expand all the compressed object groups in the RAM 2d. The system control unit 19a can use the unused area of the RAM 2d area for expanding the compressed object group as a work memory and the like, and reduce the memory amount of the volatile memory as the entire video information display control apparatus 1. Can do. For this reason, the video information display control apparatus 1 can be manufactured at low cost.

  In the first embodiment, the flowchart shown in FIG. 8 is executed every time the user performs a menu operation, but is not limited to such timing. For example, among the processes shown in FIG. 8, steps S001 to S003 are executed each time the user performs a menu operation, and steps S004 to S006 are performed at a predetermined timing after the user's menu operation ends, for example, This can be done when the user is watching a video or when the counted number reaches a predetermined number.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described.
The video information display control apparatus employing the method as shown in FIG. 1 does not use a considerable number of menu screens, but all objects are expanded in the RAM 2d. The amount of memory could not be reduced. The second embodiment aims to reduce the amount of volatile memory.
As shown in FIG. 3, the video information display control apparatus 201 according to the second embodiment includes a local bus 2a, a CPU 222b, a ROM 222c, and a RAM 222d. The video information display control apparatus 201 includes a tuner unit 4, a demodulation LSI 5, a demultiplexer 6, an MPEG2 decoder 7, a streaming reception processing unit 8, a DRM processing unit 9, a decryptor 10, and an Html browser processing unit. 11, HDD 212, network I / F 13, and AVI / O 14. Furthermore, the video information display control apparatus 201 includes an input unit 18 that receives an operation input from a user.
Here, the video information display control apparatus 201 according to the second embodiment has substantially the same configuration as that of the first embodiment, but the processing and control in the CPU 222b, the programs stored in the ROM 222c, RAM 222d, or HDD 212, and Information is different.

  FIG. 4 is a functional block diagram showing functions realized when the CPU 222b executes a program stored in the ROM 222c. The system control unit 219a is realized by the CPU 222b executing the DTV / netTV program stored in the ROM 222c after expanding it in the RAM 222d. The back-end unit 219b is realized by the CPU 222b executing the back-end program stored in the ROM 222c after expanding the RAM 222d.

  The system control unit 219a controls the entire system of the video information display control apparatus 201. In particular, the system control unit 219a controls the menu screen in the video information display control apparatus 201. Here, the system control unit 219a according to the second embodiment performs processing similar to that in the first embodiment, and also copies and expands the compressed object group OJ3 with the priority order 3 to the RAM 222d as will be described later ( Before, the processing is performed to delete from the RAM 222d the object groups (OJ1 expansion, OJ2 expansion) of priority 1 and 2 in which the compressed object groups OJ1 and OJ2 of priority 1 and priority 2 are expanded (FIGS. 19 to 22). See).

  The back end unit 219b includes a count unit 19c, a priority order determination unit 219d, a history information update unit 219e, a menu display determination unit 19f, and a divided menu file update unit 219g. The back-end unit 219b according to the second embodiment has substantially the same configuration as that of the first embodiment, but the processes in the priority order determination unit 219d, the history information update unit 219e, and the divided menu file update unit 219g are different. .

As in the first embodiment, the priority order determination unit 219d determines the usage frequency order of the target screen based on the number of times counted by the counting unit 19c.
In addition, for each determined usage frequency order, the priority order determination unit 219d calculates a usage size that is the sum of the object sizes of the screens included in the screen transition pattern that reaches the target screen in the usage frequency order. However, when calculating the use size in each use frequency order, the priority order determination unit 219d does not add the object size of the screen already added in the use frequency order higher than the use frequency order. Note that the object size is the data size of an uncompressed object (the data size of the object when expanded in the RAM 222d).
Then, the priority order determination unit 219d obtains the cumulative size for each usage frequency order by summing the use sizes in the order of the use frequency order or higher.
Furthermore, the priority order determining unit 219d calculates a cumulative size ratio (hereinafter referred to as a cumulative size ratio) in a predetermined area size (hereinafter referred to as a scheduled use size) for expanding an object in the RAM 222d.

  The priority order determination unit 219d determines the priority order of the screen transition pattern based on the usage frequency order and the cumulative size ratio. For example, the priority order determination unit 219d uses the priority order 1 when the cumulative size ratio is 80% or less, and uses the priority order 2 when the cumulative size ratio is greater than 80% and 100% or less. All of the usage frequency ranks in which the cumulative size ratio is higher than 100% are set as the priority rank 3. The threshold value (80% or 100% here) for allocating to priority 1 or priority 2 is not limited to these values.

  The history information update unit 219c selects menu screen selection history information to be described later based on the usage frequency order and priority determined by the priority order determination unit 219b and the cumulative size and cumulative size ratio calculated by the priority order determination unit 219b. 240 (see FIGS. 15 and 17) is updated.

  The divided menu file update unit 219g performs processing to update a divided menu file 250 (see FIG. 19) described later based on menu screen selection history information 240 described later.

  FIG. 14 is a schematic diagram of the object size information 60. The object size information 60 is stored in a storage unit configured by at least one of the ROM 222c, the RAM 222d, and the HDD 212. As illustrated, the object size information 60 includes an index field 61, a screen object name field 62, and an object size field 63.

The index column 61 stores an index for identifying each screen constituting the menu screen.
The object name column 62 stores identification information of objects constituting the screen specified by the index column 61. The object identification information is an object name that is a generic name of all objects necessary to realize the screen specified by the index field 61.
The object size column 63 stores the object size of all objects necessary for realizing the screen specified by the index column 61 in [MB] units. Note that the object size is the data size of an uncompressed object (the data size of the object when expanded in the RAM 222d).
For example, “Top menu screen object” is a generic name for all objects necessary to realize a Top menu screen. The “Top menu screen object” has an index of 0 and an object size of o_sz [0] = 2.5 [MB]. The “recording reservation screen object” is a generic name for all objects necessary for realizing the recording reservation screen. The “recording reservation screen object” has an index of 1 and an object size of o_sz [1] = 1.0 [MB].

FIG. 15 is a schematic diagram of the menu screen selection history information 240 (C) in the second embodiment.
Here, in FIG. 15 and FIG. 17, the symbols “C, D” in parentheses attached to the reference numeral “240” are used to indicate that the contents of the menu screen selection history information are different for each update. It is not attached when it is not necessary to distinguish between them or when generalizing them. The same applies to the following.
The menu screen selection history information 240 is stored in a storage unit configured by at least one of the ROM 222c, the RAM 222d, and the HDD 212. Note that the menu screen selection history information 240 (C) shown in FIG. 15 is in the state when the video information display control apparatus 201 is shipped from the factory.

  The menu screen selection history information 240 includes information indicating priority order, use frequency order, screen transition pattern, use size, cumulative size, and cumulative size ratio. For example, the menu screen selection history information 240 includes a table including a priority column 241, a usage frequency column 242, a screen transition column 243, a usage size column 244, a cumulative size column 245, and a cumulative size ratio column 246.

  The priority column 241 stores a value indicating the priority of the screen transition pattern stored in the screen transition column 243. The priority column 241 stores an integer value of 1 or more. The smaller the value, the higher the priority.

  The usage frequency ranking column 242 stores a value indicating the usage frequency ranking of the target screen moved by the screen transition pattern stored in the screen transition column 243. The usage frequency rank column 242 stores an integer value of 1 or more. A target screen having a higher use frequency (a higher use frequency) has a smaller value.

  The screen transition column 243 stores information indicating a screen transition pattern. The information indicating the screen transition pattern includes a screen displayed on the video display device 15 from a screen (Top menu selection screen 31) next to the top screen (Top menu screen 30) to a predetermined target screen. And the display order of the screen. Here, information indicating a screen transition pattern having a higher priority is stored in an upper record, and information indicating a screen transition pattern moving to a target screen having a higher use frequency is stored in an upper record.

The used size column 244 stores a used size obtained by summing up the object sizes of objects necessary for displaying a screen included in the screen transition pattern specified in the screen transition column 243.
However, the object size of the screen included in the screen transition pattern corresponding to the use frequency order higher than the use frequency order is not added to the use size in a certain use frequency order. For example, as shown in FIG. 15, the screen transition pattern of the usage frequency order 2 includes “Top menu screen”, “Recording reservation screen”, and “G code reservation screen”, but the “Top menu screen” is used. Since it is included in the screen transition pattern of frequency ranking 1, the object size of the “Top menu screen” is not added to the usage size of usage frequency ranking 2.

  The accumulated size column 245 stores the accumulated size in which the used sizes are totaled in descending order of use frequency rank until the use frequency rank specified in the use frequency rank column 242 is reached. For example, the cumulative size of usage frequency rank 1 is the usage size of usage frequency rank 1. The cumulative size of the records of the usage frequency rank 2 is the total size of the usage sizes of the usage frequency rank 1 and the usage frequency rank 2.

The accumulated size ratio column 246 stores an accumulated size ratio that is a ratio of the accumulated size in the planned use size.
The scheduled use size is a size of an area determined in advance for expanding the object in the RAM 222d. For example, the expected use size is obtained by the following equation (1) (see FIG. 20 or FIG. 21).
Expected use size = (object use end address 51d) − (object use start address 51c) (1)
The cumulative size ratio is obtained by the following equation (2).
Cumulative size ratio [%] = (cumulative size / scheduled size) × 100 (2)

  FIG. 16 is a flowchart showing processing when the user performs a menu operation. This flow is executed every time the user performs a menu operation. In FIG. 16, the same steps as those in FIG. 8 are denoted by the same reference numerals as those in FIG.

First, the menu display determination unit 19f determines whether or not the user's menu operation follows a screen transition pattern having a high priority in the menu screen selection history information 240 (S201).
For example, the menu display determination unit 19f determines that the screen that first transitions by the user's operation on the Top menu screen 30 matches the start screen of the screen transition pattern with priority 1 in the menu screen selection history information 240. Determines Yes in step S201.
If the menu display determination unit 19f determines Yes in step S201, the menu display determination unit 19f proceeds to the process of step S002. If determined to be No in step S201, the menu display determination unit 19f proceeds to the process of step S003.

In step S002, the menu display determination unit 19f provides the screen transition information indicating the screen transition pattern determined to match in step S201 to the system control unit 219a.
The system control unit 219a refers to the given screen transition information, and assigns the object of the screen up to the target screen and the menu control code for moving the screen to the target screen as an object group of priority order 1 (OJ1 expansion) described later. And the common menu control code group (PCO expansion) (see FIG. 20). The system control unit 19a automatically performs screen transition to the target screen by executing the acquired object and menu control code.

  In step S003, when the target screen moved by the user's menu operation is used, the count unit 19c counts (counts up) the number of times the target screen is used.

  Next, the priority order determination unit 219d updates the usage frequency order of the screen transition pattern based on the number of times counted in step S003 (S004). The priority order determination unit 219d increases the use frequency order for the screen transition pattern that reaches the target screen with the larger number of counts.

  Next, the priority order determination unit 219d calculates the use size, the cumulative size, and the cumulative size ratio based on the use frequency order updated in step S004 (S205).

  Next, the priority order determination unit 219d determines the priority order of the screen transition pattern based on the usage frequency order updated in step S004 and the cumulative size ratio calculated in step S205 (S205). The priority order determination unit 219d sets the screen transition pattern of the usage frequency order included in the cumulative size ratio below the first threshold value (for example, 80%) as the priority order 1, and the second threshold value (for example, 100%) larger than the first threshold value. The screen transition pattern of the usage frequency order included in the following cumulative size ratio is set as the priority order 2, and the screen transition pattern not included in the priority orders 1 and 2 is set as the priority order 3.

  Next, the history information update unit 219e reflects the updated use frequency order, the calculated use size, the cumulative size and the cumulative size ratio, and the determined priority order in the menu screen selection history information 240 (S207). ).

  FIG. 17 is a schematic diagram showing menu screen selection history information 240 (D) updated as a result of a user performing menu operations from the factory-set menu screen selection history information 240 (C) shown in FIG. .

For example, when the manual reservation screen 33 (see FIG. 5) is used most frequently, the screen transition pattern “Top menu selection screen (reservation) → recording reservation screen → manual reservation screen” has the usage frequency order 1. . When the volume setting screen 35 (see FIG. 6) is used the next most frequently, the screen transition pattern “Top menu selection screen (setting) → volume setting screen” is used frequency ranking 2. Hereinafter, similarly, the screen transition pattern of “Top menu selection screen (setting) → notification mail screen” is the usage frequency order 3, and the screen transition pattern of “Top menu selection screen (reservation) → recording reservation screen → G code reservation screen”. Is the usage frequency ranking 4, “Top menu selection screen (setting) → Ch scan (residence) screen → Ch scan screen → Ch registration screen” is the usage frequency ranking 5, “Top menu selection screen (reservation) → recording” The screen transition pattern of “reservation screen → program guide screen” has a usage frequency rank of 6.
The screen transition patterns having the usage frequency ranks 1 to 3 have the priority rank 1 because the cumulative size ratio is 80% or less. The screen transition pattern with the usage frequency order 4 has a priority order 2 because the cumulative size ratio is 100% or less. The screen transition patterns after the usage frequency order 5 are priorities 3.

FIG. 18 is a flowchart showing processing when the divided menu file update unit 219g updates the divided menu file 250 (see FIG. 19).
The divided menu file update unit 219g updates the divided menu file 250 with reference to the menu screen selection history information 240. When the menu operation is not performed after the update processing of the menu screen selection history information 240 is finished according to the flowchart shown in FIG. 16, the divided menu file update unit 219g is, for example, while the user is watching a program. It is desirable to update the split menu file 250 in the background.
Here, it is assumed that the divided menu file update unit 219g updates the divided menu file 250 with reference to the menu screen selection history information 240 (D). Further, it is assumed that the divided menu file 250 (old) before update is expanded in the RAM 222d. In the description here, “old” and “new” in parentheses attached to the reference numeral “250” are for distinguishing between the information before update and the information after update, and need to be particularly distinguished. It is not attached when there is no, or when generalizing and explaining.

  First, the divided menu file update unit 219g checks the screen object included in the screen transition pattern with the priority order 1 in the menu screen selection history information 240 (D) from the divided menu file 250 (old) expanded in the RAM 222d. (S300). For example, the divided menu file update unit 219g refers to the menu screen selection history information 240 (D), and creates objects for realizing a Top menu screen, a recording reservation screen, a manual reservation screen, a volume setting screen, and an information mail screen. To check.

  Next, the split menu file update unit 219g checks the screen object included in the screen transition pattern of the priority order 2 from the split menu file 250 (old) developed in the RAM 222d (S301). At this time, the divided menu file update unit 219g does not check the objects already checked in step S300. For example, the divided menu file update unit 219g checks only the object of the G code reservation screen without checking the objects of the Top menu screen and the recording reservation screen.

  Next, the split menu file update unit 219g checks the screen object included in the screen transition pattern of priority 3 from the split menu file 250 (old) developed in the RAM 222d (S302). At this time, the divided menu file update unit 219g does not check the objects already checked in step S300 and step S301. For example, the split menu file update unit 219g does not check the objects on the Top menu screen, the recording reservation screen, the manual reservation screen, the volume setting screen, the notification mail screen, and the G code reservation screen. To check.

Then, the divided menu file update unit 219g collects the objects checked in the priorities 1 to 3 from the divided menu file expanded in the RAM 222d, and sets the objects in the priorities 1 to 3 as an object group. Each of the object groups is compressed to generate each of the compressed object groups having the priorities 1 to 3 (S303).
For example, the divided menu file update unit 219g generates a compressed object group of priority 1 by compressing an object group in which objects checked in priority 1 (step S300) are collected. Further, the divided menu file update unit 219g generates a compressed object group of priority 2 by compressing an object group in which the objects checked in priority 2 (step S301) are collected. Further, the divided menu file update unit 219g generates a compressed object group of priority 3 by compressing the object group in which the objects checked in the priority 3 (step S302) are collected.

  Next, the divided menu file update unit 219g generates a fixed-length header (S304). The fixed-length header includes the addresses of the compressed object groups with priority levels 1 to 3 in the updated divided menu file 250 (new), and the expansion size when the compressed object groups with priority levels 1 to 3 are expanded in the RAM 222d. ,including.

The divided menu file update unit 219g generates a compressed common menu control code group obtained by compressing the common menu control code group developed in the RAM 222d. Then, the divided menu file update unit 219g adds the address of the compressed common menu control code group in the divided menu file 250 (New) and the expanded size when the compressed common menu control code group is expanded in the RAM 222d to the header. To do.
Then, the divided menu file update unit 219g forms the updated divided menu file 250 (new) by using the header generated as described above, the compressed object group of priority orders 1 to 3 and the compressed common menu control code group.

  FIG. 19 is a schematic diagram showing the configuration of the divided menu file 250. As shown, the split menu file 250 includes a header FH, a priority 1 compressed object group OJ1, a priority 2 compressed object group OJ2, a priority 3 compressed object group OJ3, and a compression common menu control code. A group PCO. The divided menu file 250 is all compressed except for the header FH.

  Here, the divided menu file update unit 219g may update the divided menu file 50 when the menu screen selection history information 240 is updated according to the flowchart shown in FIG. The split menu file 250 may be updated only when there is a change in the priority order in the screen selection history information 240.

  20 and 21 are schematic diagrams illustrating processing when the divided menu file 250 stored in the ROM 222c is expanded in the RAM 222d. FIG. 20 shows processing when the compressed object groups OJ 1 and OJ 2 with priority levels 1 and 2 in the divided menu file 250 are expanded in the RAM 222. FIG. 21 shows a process when the compressed object group OJ3 with priority 3 in the divided menu file 250 is expanded in the RAM 222d. The system control unit 219a deletes the compressed object groups OJ1 and OJ2 having the priority levels 1 and 2 when the compressed object group OJ3 having the priority level 3 is expanded in the RAM 222d (previous).

The divided menu file 250 is initially stored in the ROM 222c. Reference numeral 50a denotes a start address of an area where the divided menu file 250 is stored in the memory 222c. Reference numeral 50b denotes an end address of an area where the divided menu file 250 is stored in the ROM 222c.
Reference numeral 51c denotes an object use start address of an area where the compressed object groups OJ1, OJ2, and OJ3 having the priority orders 1 to 3 are expanded in the RAM 222d. Reference numeral 51d denotes an object use end address of an area predetermined as an area for expanding the compressed object groups OJ1, OJ2, and OJ3 having the priority orders 1 to 3 on the RAM 222d. Reference numeral 51e denotes an object end address of an area when all the compressed object groups OJ1, OJ2, and OJ3 having the priority orders 1 to 3 are expanded in the RAM 222d.
Note that the header FH is not expanded because it is not compressed. Since the compression common menu control code group PCO is not an object constituting the screen, it is not included in the areas 51c to 51d (51c to 51e).

Here, the total object size obtained by expanding all the compressed object groups OJ1, OJ2, and OJ3 having the priority orders 1 to 3 in the RAM 222d is obtained by the following equation (3).
Total object size = (object end address 51e) − (object use start address 51c) (3)
In the second embodiment, the expected use size, which is the size of a predetermined area for expanding an object in the RAM 222d, is changed from “object use end address 51d” to “object use” as shown in the above equation (1). This is a value obtained by subtracting the “start address 51c”.
In the present embodiment, in order to clearly reduce the amount of memory required for object expansion, the planned use size is 60% of the total object size. However, the planned use size can be changed within a range smaller than the total object size.

The system control unit 219a realized by the CPU 222b executing the DTV / netTV program uses the divided menu file 250 as follows.
First, the system control unit 219a copies the header FH of the divided menu file 250 stored in the ROM 222c to a predetermined address in the RAM 222d.
Next, the system control unit 219a refers to the address of the priority 1 compressed object group OJ1, the address of the priority 2 compressed object group OJ2, and the address of the compression common menu control code group PCO included in the header FH. . Then, based on the referenced address, the system control unit 219a reads the priority 1 compressed object group OJ1, the priority 2 compressed object group OJ2, and the compression common menu control code from the divided menu file 250 stored in the ROM 222c. The group PCO is read and copied to a predetermined address in the RAM 222d.
Next, the system control unit 219a expands the compressed object group OJ1 with priority level 1, the compressed object group OJ2 with priority level 2 and the compressed common menu control code group PCO to predetermined addresses in the RAM 222d. These are expanded into the RAM 222d to be executable programs. Here, when the system control unit 219a displays the screens of the priority orders 1 and 2, the object group of the priority order 1 (OJ1 expansion), the object group of the priority order 2 (OJ2 expansion) expanded in the RAM 222d, and The GUI is started from the program of the common menu control code group (PCO expansion).
Note that the address at which the compressed object group OJ1 with priority 1 is expanded in the RAM 2d is the object use start address 51c. The address at which the compressed object group OJ2 with priority 2 is expanded in the RAM 2d is an address obtained by adding the expansion size of the compressed object group OJ1 with priority 1 included in the header FH to the object use start address 51c.

  Note that the system control unit 219a develops the compressed object groups OJ1 and OJ2 and the compressed common menu control code group PCO of the priority levels 1 and 2 in the RAM 222d when the menu operation by the user is started (before). Thus, the GUI can be immediately started from these programs in accordance with the menu operation by the user. For example, it is desirable that the system control unit 219a expands the compressed object groups OJ1 and OJ2 having the priority levels 1 and 2 and the compressed common menu control code group PCO in the RAM 222d when the video information display control apparatus 201 is activated.

  Next, the user of the video information display control apparatus 201 uses the input unit 18 to perform an operation to display a screen that is not included in the screen transition patterns of the priority orders 1 and 2 but is included in the screen transition pattern of the priority order 3. In this case, as shown in FIG. 21, the system control unit 219a deletes the priority 1 object group (OJ1 expansion) and the priority 2 object group (OJ2 expansion) expanded in the RAM 222d. Since the screens included in the screen transition patterns with the priority orders 1 to 3 are different from each other, when the system control unit 219a displays the screen included in the screen transition pattern with the priority order 3, the object group with the priority order 1 ( OJ1 expansion) and priority 2 object groups (OJ2 expansion) need not be expanded in the RAM 222d.

Next, the system control unit 219a acquires the address in the divided menu file 250 of the compressed object group OJ3 having the priority 3 from the header FH copied to the RAM 222d. Then, the system control unit 219a refers to the acquired address, and copies the compressed object group OJ3 having the priority order 3 stored in the ROM 222c to a predetermined address in the RAM 222d.
Next, the system control unit 219a expands the compressed object group OJ3 with priority 3 to a predetermined address in the RAM 222d. The compressed object group OJ3 having the priority 3 becomes an executable program by being expanded in the RAM 222d. Note that the address at which the priority 3 compressed object group OJ3 is expanded in the RAM 222d is the object use start address 51c.
Here, when the system control unit 219a displays the screen of the priority order 3, the GUI from the program of the object group of priority order 3 (OJ3 expansion) and the common menu control code group (PCO expansion) expanded in the RAM 222d. Start up.

  As described above, also in the second embodiment, as in the first embodiment, when the user selects a large item on the Top menu screen 30, the menu screen selection history information 240 follows a screen transition pattern having a high priority. The frequently used screen is automatically displayed. For this reason, the operability of the GUI by the user is greatly improved. The priority order of the screen transition pattern is updated so that a frequently used screen has a high priority order when the user repeatedly performs menu operations. For this reason, when a user repeats menu operations, a screen having a higher use frequency of the user is automatically displayed.

  Also in the second embodiment, the divided menu file update unit 219g generates a divided menu file 250 including a compressed object group obtained by compressing the objects of each priority order based on the menu screen selection history information 240. In the second embodiment, when starting the menu operation, the system control unit 219a copies the priority 1 compressed object group OJ1 and the priority 2 compressed object group OJ2 including the Top menu screen to the RAM 222d. And expand. Therefore, the video information display control apparatus 201 according to the second embodiment can start the menu at a higher speed than when the apparatus expands all screen objects on the RAM 222d. Here, in the second embodiment, when the GUI is activated, the objects with the priority levels 1 and 2 are expanded in the RAM 222d, and therefore the display speed of the menu with the priority level 2 is higher than that in the first embodiment.

  Further, in the second embodiment, the objects of priority 1 and 2 and the object of priority 3 are not simultaneously expanded in the RAM 222d. Therefore, the size of the area where the object is expanded in the RAM 222d is Compared to Form 1, it can be about 60%. Therefore, in the second embodiment, the memory capacity of the volatile memory of the entire video information display control apparatus 201 can be reduced, and the video information display control apparatus 201 can be manufactured at low cost.

  In the second embodiment, the flowchart shown in FIG. 16 is executed every time the user performs a menu operation, but is not limited to such timing. For example, among the processes shown in FIG. 16, steps S201 to S003 are executed each time the user performs a menu operation, and steps S004 to S207 are performed at a predetermined timing after the user's menu operation is completed, for example, This can be done when the user is watching a video or when the counted number reaches a predetermined number.

  In the second embodiment described above, when it is determined that the menu operation of the user follows the screen transition pattern of priority 1, the screen is automatically transitioned according to the screen transition pattern of priority 1. However, the present invention is not limited to such a case. For example, when it is determined that the user's menu operation follows the screen transition pattern of priority order 1 or 2, the screen is automatically transitioned based on the screen transition pattern of priority order 1 or 2. It may be.

In the first and second embodiments described above, when it is determined that the user's menu operation follows the screen transition pattern of priority order 1, the screen automatically follows the screen transition pattern of priority order 1. However, the present invention is not limited to such a case.
For example, when the user returns to the top menu screen by pressing the “return” button (not shown) using the input unit 18 on the target screen that has been transitioned according to the screen transition pattern of priority 1. When it is determined that the menu operation of the user follows the screen transition pattern of priority 2, the screen may be automatically transitioned according to the screen transition pattern of priority 2.
In this case, the common menu control code (such as ActionScript in the Flash file) group may be described as shown in FIG. 22, for example.

In the first and second embodiments described above, the divided menu files 50 and 250 are the same as the compressed object groups OJ1, OJ2, and OJ3 having priority levels 1 to 3 obtained by compressing the object groups having priority levels 1 to 3. Although there is a compressed common menu control code group PCO obtained by compressing the control code group, these need not be particularly compressed. That is, the divided menu files 50 and 250 can be formed to have a header FH, a group of objects with priority levels 1 to 3 and a common menu control code group. In such a case, the divided menu file becomes a GUI program.
In this case, the header FH included in the divided menu file includes the addresses in the divided menu file of the object groups with the priority levels 1 to 3 and the expansion size when the object groups with the priority levels 1 to 3 are expanded in the RAMs 2d and 222d. , An address in the divided menu file of the common menu control code group, and an expanded size when the common menu control code group is expanded in the RAMs 2d and 222d.

In the first and second embodiments described above, the priority order is set to 1 to 3. However, the priority order is not limited to this value, and the priority order may have a plurality of orders.
In the second embodiment, the priority is set to two, 1 and 2, the threshold for assigning the priority is set to 100%, and when the cumulative size ratio is 100% or less, the priority is set to 1. When the cumulative size ratio is larger than 100%, priority order 2 can be set.
