Such as: the user may select and control items by controlling the movement of the focus object between items through a directional key on the control device. The identification form of the focus object is not limited. The location of the focal object may be achieved or identified by setting the background color of the item, or may be identified by changing the outline, size, transparency, and outline of the text or image of the focused item, and/or the font, etc.

Fig. 2A to 2I are schematic views exemplarily showing one GUI provided by the display device 200 by operating the control apparatus 100.

As shown in fig. 2A, the display device may provide a play screen 41, which may be at least one of an image, text, and video content, input by the HDMI1 to the display. For example, the playback screen shown in fig. 2A is a picture screen.

In fig. 2A, when a user wants to adjust the image quality of a playback screen displayed on the display of the display apparatus, an adjustment instruction may be input by operating the control device, and the display apparatus may superimpose and display menu contents that need to be set on the current playback screen in response to the input of the user.

For example, as shown in FIG. 2A, the user causes the display device to provide a GUI as shown in FIG. 2B to the display in response to key input by pressing a designated key, such as a setup key, on the control device, the GUI including menu content 42 and a selector 43 for indicating selection of a menu item in the menu content. Wherein the position of the selector in the menu content is movable by user operation of an input of the control means to change the selection of a different menu item.

In fig. 2B, the user operates the control device to instruct the selector 43 to select the "set image for all input sources" item, for example, pressing the up direction key on the control device, and then the user operates the control device to confirm the "set image for all input sources" item selected by activating the selector, for example, pressing the OK button on the control device, and the display device responds to the user input, and synchronously writes and stores the menu content data corresponding to each menu item in the menu content 42 to other sources except the current source, for example, the menu item: contrast value 80, brightness value 50, color saturation value 50, sharpness value 15, hue value 0; while still keeping the selector on the "apply image to set all input sources" item.

Further, in the case where the "set all input sources using images" item has been activated, the user operates the control device again to instruct the selector to select the color saturation item, the display apparatus modifies the value of the color saturation item in response to the user input for adjusting the value of the color saturation item, for example, from 60 shown in fig. 2B to 50 shown in fig. 2C, and stores the value 50 of the color saturation item in the current source; meanwhile, the value 50 of the color saturation entry is synchronously written and stored to other sources except the current source.

Further, in the case where the "set all input sources using images" item has been activated, the display device continues to modify the value of the color saturation item, e.g., from 50 as shown in fig. 2C to 40 as shown in fig. 2D, and store the value of the color saturation item 40 under the current source, in response to the user input adjusting the value of the color saturation item; meanwhile, the value 40 of the color saturation item is synchronously written and stored to other sources except the current source.

Further, in case that the "set all input sources using images" item has been activated, the user operates the control means again to instruct the selector to select the sharpness item, the display apparatus modifies the value of the sharpness item, for example, from 15 as shown in fig. 2D to 20 as shown in fig. 2E, in response to the user input adjusting the value of the sharpness item, and stores the value of the sharpness item 20 under the current source; at the same time, the value 20 of the sharpness item is synchronously written and stored to other sources except the current source.

Further, in the event that the "set all sources using images" item has been activated, the display device continues to modify the sharpness item value, e.g., from 20 as shown in FIG. 2E to 18 as shown in FIG. 2F, and store the sharpness item value 18 under the current source in response to the user input adjusting the sharpness item value; at the same time, the value 18 of the sharpness entry is synchronously written and stored to a source other than the current source.

The user then causes the display device to close menu content 42 in response to the key input by pressing a designated key on the control device, such as a back or exit key, and continue playing the screen shown in fig. 2A.

In some embodiments, as shown in FIG. 2A, the user causes the display device to provide a GUI as shown in FIG. 2G to the display in response to the key input by pressing a designated key on the control device, such as an input source key. The GUI provides an input source list interface 45 for the display device. The input source list interface 45 includes a plurality of input interfaces, such as HDMI, USB, AV, etc., for connecting to external devices, so that users can access the service contents provided by the corresponding external devices. For example, the user operating the control means instructs the selector 43 to select the HDMI2 item and activate the HDMI2 item, then the display device switches the input source to HDMI2 in response to the user input, and at the same time, displays the service content provided by the HDMI2 input source, such as the play screen 41 shown in fig. 2H.

Further, the user causes the display device to provide a GUI to the display in response to the key input by pressing a designated key, such as a set key, on the control apparatus. Here, the GUI may include menu contents as shown in fig. 2I, wherein the numerical values of the respective menu items in fig. 2I are the same as those of the respective menu items in fig. 2F, that is, the parameters related to the video mode setting under the HDMI2 input source are the same as those finally modified and set under the HDMI1 input source.

Fig. 3A to 3J are schematic views exemplarily showing one GUI provided by the display device 200 by operating the control apparatus 100.

As shown in fig. 3A, the display device may provide a play screen 41, which may be at least one of an image, text, and video content, input by the application a to the display. For example, the playback screen shown in fig. 3A is a picture screen.

In fig. 3A, when a user wants to adjust the image quality of a playback screen displayed on the display of the display apparatus, an adjustment instruction may be input by operating the control device, and the display apparatus may superimpose and display menu contents that need to be set on the current playback screen in response to the input of the user. For example, as shown in FIG. 3A, the user causes the display device to provide a GUI as shown in FIG. 3B to the display in response to key input by pressing a designated key, such as a setup key, on the control device, the GUI including menu content 42 and a selector 43 for indicating selection of a menu item in the menu content.

In fig. 3B, the user operating the control instructs the selector to select a color saturation item, the display device modifies the value of the color saturation item, for example, from 60 as shown in fig. 3B to 50 as shown in fig. 3C, in response to the user input adjusting the value of the color saturation item, and stores the value of the color saturation item 50 under the current source.

In fig. 3C, the user continues to operate the control to instruct the selector to select a contrast item, the display device modifies the value of the contrast item, e.g., from 50 as shown in fig. 3C to 60 as shown in fig. 3D, in response to the user input adjusting the value of the contrast item, and stores the value of the contrast item 60 under the current source.

In fig. 3D, the user continues to operate the control to instruct the selector to select a brightness item, the display device modifies the value of the brightness item, e.g., from 50 as shown in fig. 3D to 45 as shown in fig. 3E, in response to the user input adjusting the value of the brightness item, and stores the value 45 of the brightness item under the current source.

In fig. 3E, the user operates the control device to instruct the selector 43 to select the "set image for all input sources" item, for example, pressing the up direction key on the control device, and then the user operates the control device to confirm the "set image for all input sources" item selected by activating the selector, for example, pressing the OK button on the control device, and the display device responds to the user input, and synchronously writes and stores the menu content data corresponding to each menu item in the menu content 42 to other sources except the current source, for example, the menu item: contrast value 60, brightness value 45, color saturation value 50, sharpness value 15, hue value 0; while still keeping the selector on the "apply image to set all input sources" item.

Further, in case that the "set all input sources using images" item has been activated, the user operates the control means again to instruct the selector to select the sharpness item, the display apparatus modifies the value of the sharpness item, for example, from 15 shown in fig. 3E to 20 shown in fig. 3F, in response to the user input for adjusting the value of the sharpness item, and stores the value of the sharpness item 20 under the current source; at the same time, the value 20 of the sharpness item is synchronously written and stored to other sources except the current source.

Further, in the event that the "set all sources using images" item has been activated, the display device continues to modify the sharpness item value, e.g., from 20 as shown in FIG. 3F to 25 as shown in FIG. 3G, in response to the user input adjusting the sharpness item value, and stores the sharpness item value 25 under the current source; at the same time, the value 25 of the sharpness item is synchronously written and stored to other sources than the current source.

As shown in fig. 3E, optionally, in case that the "set all input sources using images" item has been activated, the user operates the control means again to instruct the selector to select the sharpness item, the display device modifies the value of the sharpness item, for example, from 15 shown in fig. 3E to 20 shown in fig. 3F, in response to the user input for adjusting the value of the sharpness item, and stores the value of the sharpness item 20 under the current source.

Further, in the event that the "set all sources using images" item has been activated, the display device continues to modify the sharpness item value, e.g., from 20 as shown in FIG. 3F to 25 as shown in FIG. 3G, in response to the user input adjusting the sharpness item value, and stores the sharpness item value 25 under the current source.

Further, in a case where the "set all input sources using images" item has been activated, the user operates the control means to instruct the selector to select a hue item, the display device modifies the hue item value in response to the user input for adjusting the hue item value, and stores the hue item value under the current source; meanwhile, the value 25 of the sharpness item shown in fig. 3G is synchronously written and stored under other sources than the current source.

The user then causes the display device to close menu content 42 in response to the key input by pressing a designated key on the control device, such as a back or exit key, and continue playing the screen shown in fig. 3A.

In some embodiments, as shown in FIG. 3A, the user causes the display device to provide a GUI as shown in FIG. 3H to the display in response to the key input by pressing a designated key on the control device, such as an application key. The GUI provides an application list interface 45 for the display device. Among other things, the application list interface 45 includes a plurality of applications, such as A, B, C, etc., for users to access the service content provided by the corresponding applications. For example, if the user operates the control means to instruct the selector 43 to select an item of the application B and activate the item of the application B, the display device starts the application B in response to the user input and, at the same time, displays the contents of the service provided by the application B, for example, the play screen 41 shown in fig. 3I.

Further, the user causes the display device to provide a GUI to the display in response to the key input by pressing a designated key, such as a set key, on the control apparatus. Here, the GUI may include menu contents as shown in fig. 3J, where the numerical values of the menu items in fig. 3J are the same as the numerical values of the menu items in fig. 3G, that is, the parameters related to the image mode setting in the application B are the same as the parameters finally modified and set in the application a.

Fig. 4A to 4H are schematic views exemplarily showing one GUI provided by the display device 200 by operating the control apparatus 100. As shown in fig. 4A, the display device may provide a play screen 41 of a next input source in the standard image mode to the display, and the play screen may be at least one of an image, a text, and a video content. For example, the playback screen shown in fig. 4A is a picture screen.

In fig. 4A, when a user wants to adjust the image quality of a play screen displayed on the display of the display apparatus, an adjustment instruction may be input by operating the control device, and the display apparatus may superimpose and display menu contents that need to be set on the current play screen in response to the input of the user.

As shown in fig. 4A, the user causes the display device to provide a GUI as shown in fig. 4B to the display in response to the key input by pressing a designated key, such as a set key, on the control means, the GUI including menu content 44 and a selector 43 for indicating that a menu item in the menu content is selected.

In fig. 4B, the user instructs the selector 43 to select a blue-gain item by operating the control means, the display apparatus modifies the menu content data corresponding to the blue-gain item, for example, from 3 shown in fig. 4B to 2 shown in fig. 4C, in response to the user input adjusting the value of the blue-gain item, and stores the value 2 of the blue-gain item under the current source. At this time, the user operates the control means to instruct the selector 43 to select the "adopt white balance all image mode" item, for example, by pressing the down direction key on the control means, and then the user operates the control means to confirm the "adopt white balance all image mode" item selected by the activation selector, for example, by pressing the OK key on the control means, and the display device synchronously writes and stores the menu content data corresponding to the item in the menu content 44 to a source other than the current source, for example, a menu item, in response to the user input: signal segment 80%, red-gain value 5, green-gain value 5, blue-gain value 2; while still keeping the selector stuck on the "adopt white balance all image mode" item.

Further, in a case where the "adopt white balance all image mode" item has been activated, the user operates the control means again to instruct the selector to select the red-gain item, the display apparatus modifies the value of the red-gain item, for example, from 5 shown in fig. 4C to 4 shown in fig. 4D, in response to the user input adjusting the value of the red-gain item, and stores the value 4 of the red-gain item under the current source; at the same time, the red-gain value 4 is synchronously written and stored to other sources than the current source.

Further, in the case where the "adopt white balance all image mode" item has been activated, the display device continues to modify the value of the red-gain item, for example, from 4 as shown in fig. 4D to 3 as shown in fig. 4E, in response to the user input adjusting the value of the red-gain item, and stores the value of the red-gain item 3 under the current source; at the same time, the value 3 of the red-gain is synchronously written and stored under other sources than the current source.

The user then causes the display device to close the menu content 44 in response to the key input by pressing a designated key on the control device, such as a back or exit key, and continue playing the screen shown in fig. 4A.

In some embodiments, as shown in FIG. 4A, the user causes the display device to provide a GUI as shown in FIG. 4F to the display in response to the key input by pressing a designated key on the control device, such as an image mode key. The GUI provides an image mode list interface 45 for the display device. The image mode list interface 45 includes a plurality of image modes, such as standard, sports, game, etc., for the user to view the corresponding types of service contents provided by the input sources in different image modes. For example, if the user operates the control means to instruct the selector 43 to select a moving image mode item and activate a moving image mode item, the display device switches the image mode from the standard image mode to the moving image mode in response to the user input, and at the same time, displays service contents provided by the input source in the moving image mode, such as the play screen 41 shown in fig. 4G.

Further, the user causes the display device to provide a GUI to the display in response to the key input by pressing a designated key, such as a set key, on the control apparatus. Here, the GUI may include menu contents as shown in fig. 4H, in which the numerical values of the respective menu items in fig. 4H are the same as those of the respective menu items in fig. 4E, that is, the parameters related to the 10-point white balance in the moving image mode are identical to those finally modified and set in the standard image mode.

It should be noted that the "apply image setting" function may be applied to "all input sources" or "current input source"; similarly, the above-described "adopt white balance" function may be applied to "all image modes", and may also be applied to "the current image mode". These may be configured according to the needs of the user.

In the embodiment, the menu content data set under the current source is synchronized to other sources, so that a user does not need to repeatedly modify the menu content data under different sources, and convenience is brought to the user.

Fig. 5 illustrates, as an embodiment, an implementation flow of a display device synchronizing menu content data. The process includes the following steps S51-S56:

step S51: menu content is displayed in response to user input. Such as menu content 44 shown in fig. 4B.

Step S52: the values of the items in the menu content are adjusted in response to user input. For example, in fig. 4B, the selector 43 selects an item other than "all image modes with white balance" in the menu content 44, such as a "blue-gain" item. In response to an adjustment instruction input by a user, the numerical value of the "blue-gain" item is adjusted, for example, from 3 shown in fig. 4B to 2 shown in fig. 4C, and stored under the current source.

Step S53: menu content data is synchronized to other sources in response to user input. For example, in fig. 4C, the selector 43 selects the "white balance all image mode" item in the menu content 44, and in response to the user determining this selection through the control means, the display apparatus sets the index applied to all sources and stores this index to the current position. At the same time, data in the menu content 44, such as menu item: the signal segments are on, red-gain value 5, green-gain value 5, blue-gain value 2.

Here, the synchronization process may be all image modes under all input sources, or may be all image modes under the current source, and this embodiment is not limited.

The 10-point white balance menu content 44 shown in fig. 4C is still taken as an example. The menu content 44 comprises 32 items, respectively a 10-point white balance switch, all picture modes with white balance, and 30 red, green and blue data items (10 signal segments, the next 3 red, green and blue data items for each signal segment).

The current display device includes 15 channels, 7 image modes, and 2 signal types, i.e., includes 15 × 7 × 2=210 sources. Taking data item red as an example, the corresponding relationship between the data item red and the source is shown in fig. 6. Since the data item red corresponds to 10 signal segments (denoted as Level), each signal segment corresponds to a value of the data item red, that is, the data item red corresponds to 10 values. Each source stores 10 values of data item red, and therefore the amount of data that needs to be stored is 210 × 10= 2100. The 2100 data may be stored in an array structure consisting of 2100 array elements, which is located in memory.

The display apparatus has stored the values of the items under the current source when adjusting the values of the items through step S52. The display device needs to perform an operation of synchronizing to other sources for each item in the menu content 44. FIG. 7 illustrates an implementation flow for a display device to synchronize data item Red to other sources. The flow includes the following steps S531 to S535:

step S531: and acquiring the current Source, PicMOde and Signal.

Step S532: and calculating the offset of the data item red under the current Source in the array structure through the current Source, Piccode and Signal. Since the data item red corresponds to 10 levels, 10 offsets may be determined based on each Level under the current source.

Step S533: and obtaining the value of the array element corresponding to each offset in the array structure according to each offset. That is, 10 values corresponding to the data item red under the current source are obtained.

Step S534: and traversing other sources and PicMOdes, and determining the offset of the data item red in the array structure under other sources through the other sources, the PicMOdes, the current Signal and each Level. With 10 offsets under each source.

Step S535: and respectively writing the 10 numerical values corresponding to the data item red under the current source into the storage positions determined based on the offsets of other sources.

The synchronization of the data item red is completed through the above-described steps S531 to S535. The synchronization process for the other data items is the same until the synchronization of all items in the menu content 44 is completed.

Step S54: the value of an item in the menu content is adjusted in response to user input. For example, in response to user input, the value of the "red-gain" item at the current Level (denoted as Level 0) is re-adjusted and stored under the current source.

Step S55: the values of the currently adjusted items are synchronized to other sources. FIG. 8 illustrates an implementation flow of the display device synchronizing values of currently adjusted items to other sources. The process includes the following steps S551-S554:

step S551: the stored indicator of the application to all sources is read. If the indicator indicates that the application to all sources has been selected, i.e., "all image modes with white balance" have been selected, "go to step S552.

Step S552: and acquiring the value of the current regulated item.

Step S553: and traversing other sources and PicMOdes, and determining the offset of the currently regulated item in the array structure under other sources through the other sources, PicMOdes, the current Signal and the Level 0.

Step S554: the value of the currently adjusted item is written to the storage location determined based on the offsets of the other sources.

Through steps S551-S554, synchronization of the current project is completed. The display apparatus may continue to adjust the values of the other items in response to the user input, and repeatedly perform S551-S554.

Step S56: exiting the menu content in response to the user input. For example, menu content 44 is exited in response to an input.

It should be noted that the menu content may be related to the display parameters of the content input by the source on the display. Such as picture quality data. That is, the display effect of the input content on the display can be changed by adjusting the menu content.

When the display device is switched from the current source to the other source in response to the user input, the content input from the other source can achieve the same display effect as that from the current source due to the synchronization operation performed before the switching.

Therefore, in the embodiment, the menu content data modified under the current source is synchronized to other sources, so that a user does not need to repeatedly modify the menu content data under different sources, and convenience is brought to the user.

In another embodiment, as shown in FIG. 4A, the user causes the display device to provide a GUI as shown in FIG. 4B to the display in response to the key input by pressing a designated key, such as a setup key, on the control means, the GUI including menu content 44 and a selector 43 for indicating selection of a menu item in the menu content.

In fig. 4B, the user instructs the selector 43 to select a blue-gain item by operating the control means, and the display device modifies the menu content data corresponding to the blue-gain item, for example, from 3 shown in fig. 4B to 2 shown in fig. 4C, in response to the user input adjusting the value of the blue-gain item. At this point, the user operating the control means instructs the selector 43 to select the "adopt white balance all image mode" item, for example pressing the down direction key on the control means, and then the user operating the control means confirms the "adopt white balance all image mode" item selected by the activation selector, for example pressing the OK button on the control means, the display device still keeping the selector stuck on the "adopt white balance all image mode" item in response to this user input.

Further, in the case where the "adopt white balance all image mode" item has been activated, the user operates the control means again to instruct the selector to select the red-gain item, the display apparatus modifies the value of the red-gain item in response to the user input adjusting the value of the red-gain item, for example, from 5 shown in fig. 4C to 4 shown in fig. 4D, and stores the value 4 of the red-gain item under the current source.

Further, in the event that the "adopt white balance all image mode" item has been activated, the display device continues to modify the value of the red-gain item, for example, from 4 as shown in fig. 4D to 3 as shown in fig. 4E, in response to user input adjusting the value of the red-gain item, and stores the value 4 of the red-gain item under the current source.

Then, the user presses a designated key on the control device, such as a return key or an exit key, to make the display device respond to the key input, close the menu content 44, and continue playing the screen shown in fig. 4A, while synchronously writing and storing the menu content data corresponding to the items in the menu content 44 shown in fig. 4E to other sources except the current source, such as the menu items: signal segment 80%, red-gain value 3, green-gain value 5, blue-gain value 2.

In the above embodiment, the display device does not synchronize data in the menu content with other sources when the user modifies the menu content, but synchronizes data in the menu content with other sources only in response to the user input closing the menu content.

As another embodiment, fig. 9 illustrates another implementation flow of a display device synchronizing menu content data. The process includes the following steps S81-S86:

step S81: menu content is displayed in response to user input. Such as menu content 44 shown in fig. 4B.

Step S82: the values of the items in the menu content are adjusted in response to user input. For example, in fig. 4B, the selector 43 selects an item other than "all image modes with white balance" in the menu content 44, such as a "blue-gain" item. In response to an adjustment instruction input by a user, the numerical value of the "blue-gain" item is adjusted, for example, from 3 shown in fig. 4B to 2 shown in fig. 4C, and stored under the current source.

Step S83: the set menu content data is applied to all sources in response to a determination of the user input, an indicator applied to all sources is set, and the indicator is stored under the current source. For example, in fig. 4C, the selector 43 selects the "white balance all image mode" item in the menu content 44, and in response to the user determining this selection through the control means, the display apparatus sets the index applied to all sources and stores the index under the current source.

Step S84: the value of an item in the menu content is adjusted in response to user input. For example, in response to user input, the value of the "red-gain" item at the current Level (denoted as Level 0) is re-adjusted and stored under the current source.

Step S85: in response to a user input to exit the menu content, the stored indicators of the applications to all sources are read. If the indicator indicates that the application has been selected to all sources, go to step S86. For example, in FIG. 4E, in response to a user-entered indication to exit menu content 44, the display device reads the stored indicator flags that apply to all sources. If the indicator indicates that the application to all sources has been selected, i.e., it is determined that "all image modes with white balance" have been selected, go to step S86. At the same time, menu content 46 is closed.

Step S86: menu content data corresponding to items in menu content 46 is synchronized to other sources. Referring specifically to the flow shown in FIG. 7, data synchronization of all items in menu content 44 is accomplished.

It can be seen that in this embodiment, when the user inputs an instruction applied to all sources through the control means, the display apparatus does not synchronize data to other sources. And the display device does not synchronize data to other sources for later entered modifications to the single item menu content data. And only when the menu content is closed, all data in the menu content is synchronized to other sources. The embodiment of the embodiment can enable the user to completely not perceive the time consumption of the synchronous data, and avoid the time consumption and UI pause phenomenon caused by adjusting the menu content data of a certain item for multiple times and performing the synchronous process of the current menu content data for multiple times under the condition that the user selects and applies to all source items.

The technical effect of the present embodiment will be described by taking the content of the 10-point white balance menu as an example. As shown in fig. 4E, the 10-point white balance menu content 44 includes 10 levels, each Level includes 3 data items of red, green, and blue, and 3 × 10=30 data items. The display device needs to synchronize the values of these 30 data items to other sources. Here, assuming that there are 84 other sources in total, the amount of data that needs to be synchronized is 30 × 84= 2520. For each write of data taking about 2ms, 2520 × 2=5040ms, i.e., about 5s, is required to synchronize 2520 data. In the case where the user has selected application to all source items, adjusting the menu content of an item again, it is necessary to write data to other sources 84 times, taking 84 × 2=168 ms; by continuously adjusting the contents of the 10 menu items, it takes 1.68s to write data. Then a total of 5+1.68=6.68s is consumed.

In the process of using the menu content 44, after the user selects and applies to all the source items and when the user has selected and applies to all the source items, the present embodiment adjusts the menu content again, and does not execute the synchronization operation, that is, the UI pause phenomenon will not occur due to the time consumption of the synchronization operation; but rather performs the synchronization operation after closing the menu content 44 so that the user does not feel 168ms of delay each time a certain item of menu content is adjusted and thus does not feel the effect of the synchronization operation on the UI display and operation.

While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
