Description

A menu editing method for home audio-visual equipment

technical field

The invention relates to a menu operation management method for home audio-visual equipment, in particular to implement multiple combinations of menu items by performing operations such as copying, cutting, and deleting on the menu items, so as to facilitate users to quickly operate the menu.

Background technique

In the past, the operation or setting of the radio and television program receiving device was completed by simple button operation or simple menu prompts. With the development of radio and television program receiving device technology, the functions therein also increase rapidly, and more and more operations are required, so there are correspondingly more and more menus, and it becomes complicated to complete certain menu operations. The menus of existing radio and television program receiving devices are generally designed in the form of main submenus, which solves the problem of organizing menu items under multiple menu items to a certain extent. But in this way, the user must go to different menu items or submenu items to find the desired menu item, which increases the number of button operations.

Therefore, for multi-purpose TV, its control function is very much, and the setting of menu is complicated, and operation control is also very loaded down with trivial details, without special training, a lot of users do not know how to operate at all, obviously, the setting mode of this menu cannot satisfy user's needs.

purpose of invention

The purpose of the present invention is to provide a menu editing method for home audio-visual equipment, through which the user performs operations such as copying, cutting, and deleting menu items to realize the free combination of menu items, so as to facilitate the use and quick operation of the user.

Based on this, the present invention can be realized through the following schemes:

A menu editing method for home audio-visual equipment, characterized in that the method comprises the following steps: (1) selecting one or more menu items; (2) cutting the above-mentioned selected menu items; (3) pasting the above-mentioned selected menu items item somewhere in the menu.

A menu editing method for home audio-visual equipment, characterized in that the method comprises the following steps: (1) selecting one or more menu items; (2) copying the selected menu items; (3) pasting the selected menu items item somewhere in the menu.

Usually, the menus provided by the system include menu groups with different operation contents, such as sound, image, channel, etc. Due to the adoption of the above-mentioned technical solution of the present invention, a menu group can be customized according to the user's preferences and some commonly used menu items put in it. For the menu items in such user-defined menu groups, they can also perform the above editing operations.

In addition, like some home audio-visual equipment (such as TV sets), when the user buys it back, the user needs to set up some images, sounds, and channels for the first use. Some menu items required for use are stored together, and this menu group preset by the system can also be regarded as a user-defined menu group.

After adopting the above technical solution, it can effectively solve the problem of inconvenient operation of menu items in the radio and television receiving device after the number of menu items increases; at the same time, the generation and management of user-defined menu sets in this method can enable users to directly select the functions they need most , so that the user can quickly realize the menu selection, easy to use, and simplify the control method.

The present invention can also be combined with real-time editing and management of menu item editing, so that users can set corresponding menu items according to needs, which is convenient for users to quickly realize the selected functions, and makes the operation and control of the TV more convenient and more humanized.

best practice

Figure 1 is a system block diagram of the preferred embodiment of the present invention on an analog television. It contains MCU, tuner, E ² PROM, remote control receiving part, audio and video output part, etc. The tuner is a digital tuner, which is divided into voltage synthesis mode and PLL frequency synthesis mode. The corresponding channel selection data is the tuning voltage and frequency division ratio. This program uses the frequency synthesis mode tuner, and the channel selection data is frequency division ratio. The MCU, E ² PROM and the tuner are controlled through the I ² C bus. If you want to watch which channel, MCU will get the channel selection data from E ² PROM and send it to the tuner. After the tuner receives the channel selection data, it will output a fixed intermediate frequency signal for back-end use.

For digital TV reception and decoding, it is generally done by a digital TV set-top box. The composition block diagram is shown in Figure 2, which also includes MCU, tuner, ^E2PROM , etc. The MCU, E ² PROM and the tuner are controlled through the I ² C bus.

Fig. 3 is a menu diagram containing a set of recent menu items under the same menu page with letters as accelerator keys. According to Figure 3, we can see that the menu contains many menu items, and the menu items are divided into several major groups, including recent menu, image, sound, system, and channel. Group name is generally not selected. In order to quickly locate a certain menu, here we set a shortcut key (that is, an accelerator key) for each menu item. Generally, in the existing WINDOWS operating system, the general standard PC application program menu also has accelerator keys. When opening a menu page, press the accelerator key corresponding to the menu item, and the menu item will be quickly selected and executed; in addition, in the same menu page, the accelerator key cannot be repeated, because it is impossible to perform two menu item operations at the same time. The present invention also adopts a similar operation, but we just select the menu item and do not execute the function of the menu item, so the accelerator key of the present invention can be repeated. Because it can be repeated, we can select the most representative letter or number of this menu item as the accelerator key of this menu item, which is convenient for users to remember or quickly find the rules. For example, MUTE is the mute function. For English, we can choose the letter M as its accelerator key; for those who are accustomed to Chinese pinyin, it is a good choice to choose the first letter J of its pinyin; Use the number as its accelerator key, for example, mute is the first in the recent menu group, use the number 1 as its accelerator key, and it is also the first item in the sound menu, also use the number 1 as its accelerator key, the Mute menu items in these two groups are independent. Of course, there is also a more humanized accelerator key setting method, that is, the user can set its own accelerator key for each menu item. Since the accelerator key can be repeated, this method is more suitable for users. In order to adapt to different groups, we can also selectively integrate the above-mentioned accelerator key methods in the receiving device, and provide them for users to choose, which is convenient for different users to use.

There are several ways to display accelerator keys. The first is directly displayed at the end of the menu item, as shown in Figure 3; the second is to prompt the user by adding an underline to the letter or number of the shortcut key, such as the usual WINDOWS menu; the third is displayed on the The front of the menu item, as shown in Figure 4, from the user's point of view, this method is easier to guide the user than the first two; the last method has no prompts, especially for the location as its shortcut key Menu Item.

When an accelerator key is used to quickly select a menu item, when an accelerator key is applied for the first time, the first accelerator key on the menu page is selected as the menu item of the key, and when it is pressed again, the second accelerator key on the menu page is selected. The first accelerator key is the menu item for that key, and if there is no second one, the selected menu item remains unchanged. If another accelerator key is pressed, the method is the same as described above. Of course, there are also some auxiliary menu item positioning methods, such as up and down keys 12, 14, and TAB key 11, wherein the up and down keys represent moving up or down a menu item, and the TAB key represents the first menu item from one group to the next group .

Since there are many menu items in the receiving device, the group display is only a combination of menu items, but the menu items that can be displayed on the screen of the receiving device are limited, so the menu items we display at one time are part of the menu page, as shown in Figure 21. When the accelerator key is used to quickly select a menu item, the operation is performed on the current entire menu page. The number of menu items displayed at one time is related to the specific menu generation method, and the impact on the image must also be considered. Generally, the menu items displayed at one time are between 6 and 14 items. The currently displayed menu items are dynamically combined. Of course, the number of displayed menu items can also be selected by the user himself.

To illustrate the above scheme, let us describe the relevant diagram. Figure 3 has already been said above. Figure 4 is basically the same as Figure 3, except that the accelerator keys are changed from letters to numbers. Figure 5 adds a forbidden group, which is mainly because some menu items will be unavailable due to conditions or state changes. Normally, the forbidden option will keep its position, but change its color, such as graying out, to remind the user that the menu item is unavailable. If there are many unavailable options in a certain group, when the group is displayed, the entire display area will be dominated by gray tones, which is ugly, and at the same time, the available items will not be highlighted. If the prohibited item is completely hidden, the user cannot find the menu item, and no effective prompt can be given to the user. The best way is to display these prohibited items at the end, as shown in Figure 5. It can be displayed behind the menu page in units of menu pages, as shown in Figure 9 and Figure 14, or it can be displayed collectively in an independent DISABLE group, as shown in Figure 5 and Figure 13.

Fig. 3, Fig. 4 and Fig. 5 are the situation of menu group display in a menu page mode. Figure 6, Figure 7, Figure 8 and Figure 9 are the cases where multiple menu pages are displayed separately. In this case, the selection of the accelerator key is performed on a single menu page, and the operation method is basically the same as the operation method described above.

Figure 19 and Figure 20 are the remote controller used by the receiving device. in:

1 is an infrared signal generator;

Copy key 17, paste key 18 and cut key 19 are used for regrouping menu items, which will be described in detail later;

Key 21 menu setting key, key 20 menu item key are also used for recombination of menu items, and will be described in detail in the following description;

In fact, the accelerator key does not need to be marked in the menu item, but an implicit relationship, such as pressing the number key 1, the first item will be selected. As long as the corresponding relationship between such keys and menus is included, it should belong to the idea of the present invention.

The settings and operations of the accelerator keys have been mentioned above. Next, let’s talk about the generation and operation of the recently used menu and the most frequently used menu.

In a literal sense, the recently used menu is considered from the perspective of time, and the most frequently used menu item is considered from the frequency of use of the menu item. The first is the recent menu. Figures 3 to 14 show different applications of the recently used menu from different application occasions. Fig. 3 to Fig. 5 show that the recently used menus are collectively displayed under a single menu page with independent recently used menu groupings. It can be seen that the recently used menu grouping is at the top. Press the menu key 4 for the first time, and the menu page will pop up on the screen, that is, the display of the menu page starts from nothing. . For the case where numbers are used as accelerator keys, the accelerator keys are set according to their positions in the group. The corresponding recently used menu items here are 6 items in total. Certainly also can be less or more, also can be set by user oneself. If the current recent menu is less than 6 items, the remaining items are vacated, as shown in FIG. 5 .

Figure 6 shows a recently used menu using a separate menu page. Fig. 6, Fig. 7 and Fig. 8 are three menu pages among the menu pages displayed separately. Press the menu key 4 for the first time, the screen pops up the menu page, first display the recently used menu page shown in Figure 6, then press the menu key 4, switch to Figure 7, then press the menu key 4, switch to Figure 8, By analogy, when the last page is reached, the user returns to the recently used menu page shown in FIG. 6 . The corresponding recently used menu items here are also 6 items in total. Certainly also can be less or more, also can be set by user oneself. If the current recent menu is less than 6 items, the remaining items will be vacated.

FIG. 9 shows another implementation of the recently used menu, taking the sound menu as an example. In the sound menu page, the most recently used menu items Mute and Treble in the sound menu are displayed first, and then the menu items contained in the sound menu, including available menu items and unavailable menu items. The corresponding recently used menu items here are also 2 items in total, and can also be set by the user himself, since this is for a certain menu page, the number should not be too much. If the current recent menu is not full of 2 items, the less than full items will be vacated. For the case where the number keys are used as accelerator keys, the accelerator keys are calibrated separately, as shown in Figure 9, the treble is the second item in the recent menu item, the accelerator key is 2, and it is the third item in the menu item , the accelerator key is 3. Because the number accelerator key is related to its position in the menu group. As for the letter, it is generally fixed because it is related to the meaning of the menu item.

The application of recently used menu items is a dynamic process, and generally does not need to be stored in NVRAM. In this way, the content corresponding to the recent menu item is empty when it is used for the first time, which will also cause the entire screen display to be ugly at the beginning. The best way is to first set a set of default values for the most recently used menus based on statistical rules or the results of user operation habit surveys. When the receiving device is powered on and running, the latest menu default value is loaded for the first use.

According to the idea of the recently used menu, it forms a list of the user's recent use based on the historical records of the user's operation process. According to this idea, it can also be recently used channels, including channels and channels, as shown in Figure 10; recently used tools, as shown in Figure 11; recently played games, as shown in Figure 12, etc. .

Figure 13 and Figure 14 are the applications of the recent menu under the multi-level menu. Figure 13 shows the recent menu as a single sub-menu item, which is also displayed at the top. Fig. 14 is another implementation of the recently used menu under the multi-level menu. In the sound submenu, the most recently used menu items Mute and Treble in the sound menu are displayed first, and then the menu items contained in the sound menu, including available menu items and unavailable menu items. The corresponding recently used menu items here are also 2 items in total, and this number is the same as that mentioned above, which can be set by the user himself. Since this is for a menu page, the number should not be excessive. If the current recent menu is less than 2 items, the remaining items will be vacated. For the case where the number keys are used as accelerator keys, the accelerator keys are calibrated separately, as mentioned above, because the number accelerator keys are related to their positions in the menu group; for letters, because they are related to the meaning of menu items, they are generally fixed. .

The display of the recent menu is a process of generating and displaying a dynamic combination of menu items. Similarly, the aforementioned dynamic shortcut key display is also a process of dynamically combining menu items to generate a display. Let's take the generation of the menu page shown in Figure 4 as an example for illustration, and its display content is shown in Figure 21 . Figure 4 contains all menu items, and Figure 21 is the menu items actually displayed on the screen. When designing a menu, we design it in units of menu items. Each menu item includes an ID. Here is part of the structure of the menu item:

1) Menu item ID;

2) Menu item name;

3) Accelerator key;

4) Variable ID;

5) Display control type;

6) Display attributes;

7) Adjust function ID;

8) Menu item attributes;

9) Number of uses;

10) The menu group to which it belongs;

11) Whether it is deleted;

Wherein the menu item ID is unique to the device. The menu item name is the name of the menu item, such as brightness, contrast, etc. Accelerator keys include the above mentioned ones, English accelerator keys, Chinese Pinyin accelerator keys, user-set accelerator keys, and number accelerator keys; English accelerator keys and Chinese Pinyin accelerator keys are set by the system, and user-set accelerator keys It is set by the user, the data needs to be stored in NVRAM, and the numeric accelerator key is dynamically generated when the menu item is loaded. The variable ID refers to the variable ID that executes the operation of the menu item. If the ID is 0, it indicates that the operation is only an action, not for a certain variable; in addition, the variable ID is also the unique identification number for the variable defined by the system. The display control type refers to what form is used to represent the variable or the operation. Such as progress bar, edit box and so on. The display property includes the size, color, selected state, prohibited state, etc. of the control, which are related to the display. The adjustment function ID refers to the function ID called when the menu is executed, and it is also the unique identification number of the adjustment function set by the system. The menu item attributes include whether to select, whether to prohibit, etc., which are dynamically generated. The number of uses is dynamic, and the value of this item is increased by 1 each time it is used, mainly to generate a list of the most frequently used menu items. The menu group to which it belongs is the group category of the menu item, such as image, sound, and the menu item will be displayed in the corresponding group. The relationship between the menu direction and the menu group to which it belongs is a one-to-many relationship, that is, one menu item can appear in many at the same time. There are two menu groups, but generally not more than two, and one belongs to the menu group defined by the system, and the other belongs to the menu group defined by the user. Whether it is deleted refers to the system menu group. If a menu item is deleted by the system menu group, the data can be reflected. If it is in the user menu group, just delete the user group in the menu group to which it belongs. . The editing of menu items will be described in detail later.

In order to dynamically generate the menu page, we need to open up a space to load the menu page. The group name is also regarded as a menu item, and nine menu items are displayed on the screen at a time. Since the six most recent menu items are included, there is a queue of length six, with each element in the queue containing the following:

1. Menu item ID;

2. The last value;

The last value is the value before the menu item variable is adjusted. At the end of each menu item operation, the above two values will be put into the head of the queue, and at the same time, the items will be moved backwards, and the last item at the end of the queue will be dequeued. Assume that our recent menu queue contains the six items shown in Figure 21, namely MUTE, VOLUME, BRIGHTNESS, CONTRASTNESS, SHARPNESS, and SATURATION. In addition, if it is indeed used for the first time, you can also use the recent menu list given by the system according to the statistical results. Of course, these menu items are not used recently. It can be the most frequently used menu list described later, just as Default menu option.

At the same time, in order to display the fixed items, there should be a corresponding fixed menu item form in the system. Combined with the recent menu list above, the menu page can be generated. First, press the menu button, and after confirming that the menu is to be displayed, the system clears the contents of the loaded menu page space, where the menu page space is nine menu items long. First load the name of the nearest menu group, then find the menu item through the menu item ID recorded in the content of the recent menu list, set the menu item attributes such as whether the menu item is selected or disabled according to the current state, and then set the loading acceleration according to the accelerator key Key name and menu name, and then load the control according to the value of the variable and the display control type, and modify the display property according to the content of the display property, so that a menu item is loaded; and so on, after the recent menu list is loaded, according to the fixed menu The record of the item form and the current display position, also use the above method to load the fixed menu item. After the loading is complete, the output can be displayed.

The menu generation system of the radio and television receiving device, which is generally called the OSD system, includes a font library, a video memory, and a character insertion device. The loading process of menu items is to express the content to be displayed by the dot matrix data of the font library through the program, and include display attributes, such as color, and put these into the video memory, and then the video memory inserts the above data into the image signal. This will display the menu items on the screen. The generation of dynamic menus should be a very mature technology technically, especially the menus in WINDOWS are all dynamically generated. For a radio broadcast television receiving device, the dynamic menu is the control of the loading process. The loading process determines which menu items are displayed, how they are displayed, and so on. As long as there is program-controllable video memory, menu items can be dynamically loaded, and most menu systems are now dynamically loaded. The subject of the present invention is not how to generate a dynamic menu, but what kind of dynamic menu to generate.

If the currently displayed menu page includes the display of the recently used menu, as shown in FIG. 9 , there will be some trouble if it needs to be updated in real time, although technically this is not a problem. Because the recently used menu items must be refreshed after each menu operation, frequent changes will bring trouble to the user and add a certain degree of complexity to the design. The best way is to use a temporary space to store the current recently used menu. When exiting the menu page, add the newly obtained recently used menu to the recently used menu queue to ensure that the next time you see the recently used list is an updated list. . That is, the currently displayed recent menu remains unchanged, and will only be reloaded and displayed the next time it is displayed. Figure 31 to Figure 33 show the recent menu generation process. Initially empty, as menu items are manipulated, the queue moves backwards until the queue is full. After the queue is full, the new menu item operation occupies the head of the queue, the others move backwards one by one, and the last one is squeezed out of the queue.

The most frequently used menu list is a user menu list formed according to statistical rules. The system has a preset most frequently used list for the first boot. In this way, the preset most frequently used list includes the menu items that the user needs to use when starting up for the first time, such as automatic channel search, volume, brightness, contrast and so on. It can also be a menu item given after certain statistics. The preset use times of the preset menu items are equal to 5, and the use times of the other menu items are 0, so that the most frequently used menu list can have certain stability. In subsequent menu item operations, each menu item operation will add 1 to the usage times of the menu item. In order to avoid overflow, you can also set a large number, and when this value is exceeded, the count remains unchanged. When the most frequently used shortcut key is pressed, the system will find out the 6 most frequently used menu items from all menu items according to the usage times of the menu items, generate a menu page and display it.

Generally, we will store the first 6 most frequently used menu item IDs, so that every time the power is turned on directly, the most frequently used menu list will not be preset by the system, but will change according to actual use. At the beginning, the use times of each most frequently used menu item are the same as the previous preset use times, and the use times of other menu items are 0.

According to the idea of the most frequently used menu list, it forms the user's most frequently used menu list according to the historical data statistics of the user's operation process. Following this idea, it could also be the most frequently used channel, the most frequently used channel, the most frequently used tool, the most frequently used game, etc.

The accelerator key, the recent menu, and the most frequently used menu are described above, and the generation method and management of user-customizable menu items are described below.

The menus of existing radio and television receiving devices are generally fixed by the system, or change according to the settings of the system, including the recent menu and the most frequently used menu, but there are no menu items or menu pages that can be defined by the user.

Since the generation method of the dynamic menu is described above, there is no problem in generating and displaying a menu page for the free combination of menu items. The customization of menu items includes the name and icon of the custom menu group, and the addition and deletion of corresponding menu items. In addition, the management of the custom menu group includes copying, copying, moving, etc. of the menu group.

In order to effectively manage the user-defined menu group, a key 21 menu setting is provided on the remote controller for setting the user-defined menu group. Press this button, and the menu shown in Figure 18 will be displayed on the screen. Through this menu combined with button operations, the copying, copying, and moving of the menu group can be completed. It can be seen from Figure 18 that the menu items include User 1, User 2, and New. User 1 and User 2 are two user menu groups that have been established by the user. Figure 15, Figure 16 and Figure 17 show several display schemes of user-defined menus. Figure 15 puts this menu in the main menu and displays it together. The custom menu is a submenu group under the main menu, and the whole is a multi-level menu. Figure 16 shows user-defined menu items in the form of a single-page menu, and all customized menus are displayed on the same menu page. Figure 17 shows the user-defined menu as a multi-level menu.

Since our menu grouping is dynamic, changes to the menu grouping must be stored. The stored data of each menu group is organized as follows:

12) Menu group number;

13) Group name;

14) icon;

15) System grouping or user grouping;

Whether the group is deleted;

Also, since our menu items are dynamic, changes to menu items must be stored. The stored data for each menu item is organized as follows:

16) Menu item ID;

17) The group number of the menu to which it belongs;

18) The order in the menu grouping;

In order to create a new user-defined menu group, you can select the new menu item in the menu shown in Figure 18, and after confirmation, a menu group with empty menu items will be generated, which will be added after the user 2 menu item and marked as user 3. The default name is also user 3, and the default icon is icon 1, or some unused icon. After generating a new menu, the user can edit the name of the menu group, select an icon, and the modified data will be stored in NVRAM. When the menu group is displayed, what is displayed on the screen is the name set by the user or the icon set by the user. The displayed icons are shown in Figure 15, Figure 16 and Figure 17. Figure 15 and Figure 16 are displayed in text, and Figure 17 is displayed in the form of icons.

After creating a new user menu group, you need to add menu items to the new user menu group or the existing user menu group. First enter the main menu, press the menu item key 20, the system enters the menu editing state, at this moment all menu operations are invalid. In the menu editing state, press the menu key 4 or the menu item key 20, and the menu editing state ends. The editing methods of menu items are mainly completed in three ways: copy, cut, and paste. There are three ways to add menu items.

The first method is to copy the menu items in other menu groups or groups, and copy them to the newly created menu group. When selecting the group name or grouping icon and pressing the copy key 17 to perform the copy operation, all the menu items contained in the group will be copied; when selecting a certain menu item and pressing the copy key 17 to perform the copy operation, the copy operation Just copy individual menu items. If the user selects another menu grouping and presses the paste key 18 to perform the paste operation, then the copied menu item will be added to the current menu grouping, and the menu grouping of the menu item will add the current menu grouping, and the menu item will be Appears in two menu groups.

The second method is through the cutting operation. When selecting the group name or grouping icon and pressing the cut key 19 to perform the cutting operation, all the menu items contained in the group will be cut; when a certain menu item is selected and pressed When the cut key 19 performs a cut operation, the cut operation only cuts a single menu item. It saves the cut content to a temporary storage area when cutting the menu grouping or the menu items in the grouping. At this time, if the user selects another menu grouping and presses the paste key 18 to perform the paste operation, the cut menu Items are added to the current menu group. At this time, the previous group number of the menu group to which the menu item belongs is deleted, and the current group number will be written into the group to which it belongs. If the cut is the entire group, and it is a system group, then the option whether to delete the group is set to delete, and the group to which the menu item it contains will also delete the group number. If it is a user group, the group will be deleted directly, and the group number of the menu item it contains will also be deleted. If a menu item is cut, the group to which the menu item belongs will also delete the current group number, and the group to which it belongs will be set as the current group when pasting.

The third method is to select a current menu group A, and let the system enter the menu item editing state of menu group A through some means, such as shortcut keys or menu settings. At this time, when the user enters other menu groups and selects a certain menu item, presses the paste key 18, the menu item will be added to the selected current menu group A, and the group to which the menu item belongs will increase the current group A. When entering the current menu group of settings again, the newly added menu items will be displayed. If the user presses the cut key 19 in the current menu group A, the menu item will be deleted, and the group to which the menu item belongs will also delete the current group A. This process continues until the user exits the menu item edit state.

For method three, there is another use to adjust the display order of menu items. If the user selects a menu item in the current menu group A, presses the volume plus key 13, then selects the menu item, then adjusts its position through the program plus and minus keys 12 and 14, and updates all menu items in the menu group Set in the position of menu group A. Press volume up key 13 again to confirm and save.

In order to prevent misoperation, a confirmation mechanism can be designed, especially when deleting an operation, the user is first prompted to delete, if the user confirms the operation, the operation is performed, otherwise no operation is performed. In addition, the operation of this menu item can be limited to the operation of user-defined menu items, and the built-in menu of the system does not allow users to modify, but their menu items can be copied. But it is also possible to modify the built-in menu of the system, and the above solution also includes the modification of the built-in menu of the system. Figure 22, Figure 23 and Figure 24 describe the settings for the entire menu, including system built-in menus and user-defined menus, which settings include the names of menu groups, icons, and included menu items. Since the menu group contains icons and text, the system can also choose whether to output the menu group with icons or text. Figure 15 shows menu groupings in text, and Figure 24 shows menu groupings in icons. Of course all changes to these menu items or menu groupings will be saved to NVRAM.

When the receiving device adjusts parameters through the factory menu, not all parameters need to be adjusted. A batch of machines may only need to adjust a few of them, but these parameters may not be on one menu page. At this time, if Being able to dynamically combine these adjustment items into a menu page will greatly facilitate factory debugging. Of course, it can definitely be achieved using the above method. In addition, since the user menu is defined by the user, it is more suitable for the user's needs than other menus. Users can choose the user's preferred method through certain means, such as selecting the user-defined menu group when entering the menu by default or grouping the user Custom menu groups are placed before the groups contained in the menu.

Figure 25, Figure 26, Figure 27, and Figure 28 show another menu scheme of dynamic menu combination. Figure 25 is the main menu diagram. Press the menu button for the first time, and the image will be displayed on the screen. At this time, if the user moves the cursor to the sound menu group and confirms, all menu items in the sound menu group will be loaded into the menu page, located under the Sound menu grouping. The down key 12 and up key 14 are used to move through menu groupings and expanded menu items. Press the button volume plus and minus key 5 or 13, when the menu group is selected, it means confirmation. If the menu item is expanded at this time, the expanded menu item will be retracted, otherwise it will be expanded; when the selected menu item is specific, if This menu item is used to adjust the value of the variable, adjust the value, if the selected menu item corresponds to another menu page, it will jump to another menu page. Continue to move the selected menu item. When the selected item is system, the system menu will expand after confirmation, as shown in Figure 27. However, this solution will cause too many menu items, which is not easy to display. Another method is to limit that only one menu group can be expanded at a time. In this case, when the selected item is the system, the sound menu item will be retracted after confirmation. Expand the system menu, as shown in Figure 28. Another method is that once a certain menu grouping is exited, the expanded menu items of the grouping will no longer be maintained and will be retracted automatically. In this case, when the selected item is the system, it will be displayed as shown in Figure 25, and it has been automatically retracted at this time Sound menu item, expand the system menu after confirmation, as shown in Figure 28. There is another method, that is, once a certain menu group is entered, the group will be automatically expanded and displayed. In this case, confirmation operations can be reduced. The above operation is different from the existing hierarchical menu, because the grouping display position of the existing hierarchical menu basically does not change, but the display position of the menu grouping in this solution is dynamically changed.

The menu schemes shown in Figure 25, Figure 26, Figure 27, and Figure 28 correspond to any position on the screen, but because it is a single-column menu, it is a better solution to display on the side or at the corner, so that the impact on the image will be relatively small . When the menu is located in the lower left corner or lower right corner of the screen, the expansion direction of the menu is upward; when the menu is located in the upper left corner or upper right corner, the expansion direction of the menu is downward. In addition, whether the expansion item is placed above or below the menu group name also needs to be considered. The expansion item in Figure 28 is placed below the menu group name, while the expansion item in Figure 29 is placed above the menu group name. This is related to the direction of the selected operation. If the selected operation is from top to bottom, the expanded item will be placed above the menu group name; if the selected operation is from bottom to top, the expanded item will be placed below the menu group name. Especially in the case of automatic group expansion, using this scheme can reduce misoperations.

In order to make the menu beautiful and tidy, the expanded menu items do not need to be aligned with the menu group name, but shrink according to the principle of shrinking toward the middle of the screen to achieve a hierarchical effect. In addition, different colors can be used to distinguish menu groups and the menu items contained in the groups.

As mentioned earlier, the recent menu item is a queue with a length of six, and each element in the queue includes the menu item ID and the last value. According to this queue, the operations of UNDO and REDO can be easily realized, but its length can only be 6, that is, there can only be a maximum of 6 histories that can be repeated. Since some operations involve a large amount of data, such as automatic channel search, they can be ignored under normal circumstances. If the memory space used by the system is relatively large, this operation can also be considered. There are also some functional menu item operations, such as entering another menu, it will also be added to the recent menu list, but if there is no parameter or system status change, UNDO/REDO has little meaning. Here we take the recent menu in Figure 4 as an example to illustrate. It contains 6 items, and the following are the names, IDs, and last values of these 6 items.

Mute (MUTE) 0x0001 Off

Volume (VOLUME) 0x0002 30

Brightness (BRIGHTNESS) 0x0003 20

Contrast (CONTRASTNESS) 0x0005 35

Sharpness (SHARPNESS) 0x0008 42

Saturation (SATURATUION) 0x0020 34

The values shown on Figure 4 are current values. The corresponding queue is shown in Figure 32 and Figure 33, the current position indicator mark 30 is at the forefront of the queue, the last value queue 31 of the menu item is on the top, the current value queue 32 of the menu item is below, and the current position indicator mark 30 reaches the head of the queue It belongs to the record that can be operated by REDO, and the current position indication mark 30 to the end of the queue belongs to the record that can be operated by UNDO. In Fig. 32 to Fig. 42, the current position indication mark, the last value queue of the menu item and the current value queue of the menu item are similar to those shown in Fig. 32 and are not marked in the figures.

A variable is also needed here to record the position of UNDO/REDO, corresponding to the current position indicator 30, the variable name is CUR_POS_OF_DO, the initial value is negative, at this time, UNDO and REDO are prohibited, and the maximum value is 5. Once there is a menu item operation, the recently used menu item queue has a record, and CUR_POS_OF_DO is set to 0. Here set CUR_POS_OF_DO to 0, and the REDO operation is prohibited at the beginning. Press the UNDO key 7, the last mute operation will be canceled, the current value of mute will be turned off, and the last value of the mute record in the queue will be turned on, and CUR_POS_OF_DO will be increased by 1, as shown in Figure 34. At this time, REDO can be operated; Then press the UNDO key 7, the volume operation is cancelled, the current value becomes 30, the last value becomes 50, and CUR_POS_OF_DO is increased by 1, as shown in Figure 35. At this time, press REDO key 6, the volume operation is resumed, the current value becomes 50, the last value becomes 30, CUR_POS_OF_DO minus 1, as shown in Figure 36. At this time, the menu item performs the treble adjustment operation, and the treble operation is added to the head of the queue, the other items are moved backward, and the saturation at the tail of the queue is removed from the queue, as shown in Figure 37.

Fig. 30 shows a flow chart of UNDO/REDO operation for the above operation. It can be seen from the figure that once there is a menu item operation, CUR_POS_OF_DO is set to 0; if the record at the position of CUR_POS_OF_DO in the queue is not to operate on variables, but to perform unrecoverable operations such as automatic channel search or pop-up of a new menu as described above Or for operations that do not need recovery, just change CUR_POS_OF_DO and do nothing. The above-mentioned menu item operation is to open the main menu, select a menu item and perform an operation, or a shortcut menu operation.

The above UNDO/REDO operation utilizes the recent menu list, we can also create a separate UNDO/REDO queue, the queue elements are the same as the recent menu list, and the length is still 6. The UNDO/REDO operation process is similar to that described above. It’s just that if the current menu item operation is not an operation on variables, but an unrecoverable operation or an operation that does not need to be restored, such as the automatic channel search or pop-up of a new menu mentioned above, the operation will not be added to the UNDO/REDO queue. In this way, the UNDO/REDO operation does not need to judge whether the record at the CUR_POS_OF_DO position in the queue operates on variables.

Using the recent menu list and creating a separate UNDO/REDO queue for UNDO/REDO operations, there is one more difference between the two methods that can be done in the insertion position of the current menu item operation in the respective queue and the UNDO/REDO queue processing. Because the recent menu list must ensure the correct display of the recently operated menu items, the current menu item operation must be at the forefront of its queue, and the subsequent ones will move backward. As for the UNDO/REDO queue, the insertion position of the current menu item operation can be determined according to the needs of the system. The simplest way is that once a menu item operation is inserted, the current menu item operation is inserted in front of the position indicated by CUR_POS_OF_DO, and the current menu item operation and the menu item operations behind it move forward until the current menu item moves to the head of the queue. If CUR_POS_OF_DO indicates that the position is already the head of the queue, the entire queue will be moved back one position, and the current menu item operation will be placed at the head of the queue. Taking the queue shown in Figure 38 as an example, both REDO and UNDO operations can be performed at this time. Assuming that a treble menu item operation is inserted at this time, it is inserted and moved forward, as shown in Figure 39. There is another bass operation, since the position indicated by CUR_POS_OF_DO is already the head of the queue at this time, it is moved backward and inserted as shown in Figure 41. Do another color temperature operation, similarly, move back and insert, as shown in Figure 42, but at this time, the tail of the line changes from the previous saturation to the clarity. This method is simple, and if the queue length is long enough, the system can always recover to the original state.

There is another method, also taking the queue shown in FIG. 38 as an example, assuming that a treble menu item operation is inserted at this time, and it is inserted and moved forward, as shown in FIG. 40 . Comparing Figure 39 and Figure 40, it can be found that the records belonging to the REDO operation before the position indicated by CUR_POS_OF_DO are moved forward by one position as a whole, and the vacant position is reserved for the current menu item operation treble, and CUR_POS_OF_DO is also moved forward by one position, and the mute operation is due to Overflows are removed. Another bass operation, after the records belonging to the REDO operation before the position indicated by CUR_POS_OF_DO are moved forward by one position, all REDO operation records are cleared due to overflow, the bass operation is at the head of the queue, and CUR_POS_OF_DO moves forward by one position to indicate the head of the queue. REDO is disabled at this time. Do another color temperature operation. At this time, the position indicated by CUR_POS_OF_DO is already the head of the queue. The processing method is the same as before, after moving back and inserting, as shown in Figure 42, but at this time the tail of the queue changes from the previous saturation to the clarity. This method can keep as many operation records as possible. If the queue is long enough, the REDO operation record will not overflow after moving forward, but will add a record forward to the queue, and the entire queue will become longer. After adopting this method, all operations can be restored, truly realizing UNDO and REDO operation.

We can also perform UNDO/REDO operations on the operation of a variable separately, so that the change process of the variable is recorded in the queue. Executing UNDO/REDO can reproduce the change process of this variable. In the radio and television receiving device, the variables that most need this kind of operation are generally the ones that change in a large range and change discontinuously, such as the current channel, the current channel, the currently selected menu item, and so on. There are many ways to change channels in a general radio and TV receiving device. In order to facilitate the user to find, it is very useful to use UNDO and REDO to record the process of changing channels. The current channels include TV, AV, S-VIDEO, YUV, VGA, HDTV, DVI and HDMI, and some data channels such as USB, card reader, using UNDO, REDO operation so that users can conveniently switch between several ports switch. The current menu item is the menu item currently operated by the user. By saving the menu item history of these selected operations, it is also possible to quickly switch back and forth between several menu items. Since each menu item in our system has an ID, these Menu items can belong to different menu pages, so that quick switching of menu pages is also completed.

For some operations performed automatically by the system, it is not easy for the user to recover after the operation is completed. At this time, UNDO and REDO operations are also required. Such as automatic station search, automatic geometric adjustment, and so on. The most fundamental condition for UNDO and REDO operations to be realized is to save the data before the change in the queue. The same is true here. Before the automatic operation is executed, a backup of the data to be operated is reserved. If the result of the automatic operation is not satisfactory, it is still possible. Revert to the data before the operation. Automatic channel search is an automatic channel search action. The data changes before and after the channel search are relatively large, such as missing channels, frequency deviation, user adjustment data loss, etc., which may affect the normal viewing of users. To complete UNDO and REDO operations, it is necessary to The data space is relatively large, but it is useful for actual use. Automatic geometry adjustment is generally used in CRT TV factory debugging. In a reference mode, adjust the field geometry and line geometry parameters, and other modes automatically calculate the corresponding parameters according to the preset offset. Sometimes The result after automatic adjustment is unsatisfactory, and the parameters before adjustment need to be restored. In this case, using UNDO and REDO operations can make the operation more convenient and more humane.

For a certain adjustment, it is completed by the adjustment of multiple parameters. Because the adjustment is more complicated, sometimes the effect is worse after the adjustment. For example, TV image effects, users can adjust brightness, contrast, saturation, sharpness, color temperature, scan mode, noise reduction, etc. There is a certain coupling relationship between these parameters, and only when they are well matched can there be an optimal good image effects. Generally, users may not have experience in adjustment, which often results in lower image quality. In this case, using UNDO and REDO operations can restore the user's operation to a certain state, which is convenient for users to adjust.

The foregoing is only an embodiment of the present invention, and any use of the ideas and similar technical solutions of the present invention to realize rapid management and editing of TV functions should fall within the scope of protection of the present invention.
