Referring to FIG. 4, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (referred to as an "application layer"), an application framework layer (Application Framework layer) (referred to as a "framework layer"), a An Zhuoyun row (Android run) and a system library layer (referred to as a "system runtime layer"), and a kernel layer, respectively.

In some embodiments, at least one application program is running in the application program layer, and these application programs may be a Window (Window) program of an operating system, a system setting program, a clock program, or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an application programming interface (application programming interface, API) and programming framework for the application. The application framework layer includes a number of predefined functions. The application framework layer corresponds to a processing center that decides to let the applications in the application layer act. Through the API interface, the application program can access the resources in the system and acquire the services of the system in the execution.

As shown in fig. 4, the application framework layer in the embodiment of the present application includes a manager (manager), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used to interact with all activities that are running in the system; a Location Manager (Location Manager) is used to provide system services or applications with access to system Location services; a Package Manager (Package Manager) for retrieving various information about an application Package currently installed on the device; a notification manager (Notification Manager) for controlling the display and clearing of notification messages; a Window Manager (Window Manager) is used to manage bracketing icons, windows, toolbars, wallpaper, and desktop components on the user interface.

In some embodiments, the multi-window function based on the Android system is a function of simultaneously displaying two application windows on one device screen. Under the state of multiple windows, different split screen templates can be displayed according to different channels, for example, an HDMI (high definition multimedia interface) channel can simultaneously display an HDMI channel video picture and a single-channel screen projection picture, and an Android channel can simultaneously display two-channel screen projection pictures or a single-channel screen projection picture and any application picture. Taking the multi-window portal application in fig. 4 as an example, in the multi-window application, the same split-screen template displays different split-screen contents under different signal source channels. As an example, a split screen film viewing template is taken as an example, and after the split screen template is started under an Android channel, a display device side can simultaneously display the currently watched content and the mobile phone screen throwing content; and displaying the physical channel content and the mobile phone screen contents in the same interface under the physical channel. For example, after a remote controller shortcut key binds a split screen viewing template under a physical channel, a user switches to the Android channel, and then starts the bound split screen template through the remote controller shortcut key.

As another example, the "two-way screen-throwing" split-screen template is to display the screen throwing contents of two mobile phones at the display device end, and because the physical channel and the Android channel are two different audio/video interfaces for different audio/video transmission, if the "two-way screen throwing" template is directly opened under the physical channel, the audio playing under the HDMI channel is not terminated at this time, which results in the abnormal situation that multiple channels of audio are simultaneously played, the current channel needs to be switched to the Android channel under the scene.

Therefore, if the corresponding relation between the split screen template and the channel cannot be changed according to the fixed value defined by the requirement, and the fixed value is uniformly managed by the multi-window portal application, the coupling between the applications is stronger, so that when the subsequent split screen template references the requirement change (the channel corresponding to the same split screen template changes), the multi-window portal application also needs to be synchronously changed, and the maintenance cost of the multi-window portal application is increased. Meanwhile, due to the dependency relationship among the applications, the difficulty of subsequent self-upgrading through single application is increased.

Aiming at the problems, the application provides the display equipment and the display control method, whether the current split screen template needs channel switching and the start of the split screen template is judged according to the binding information in the setting database when the split screen template is started through the shortcut key of the controller, meanwhile, the channel switching is carried out through the existing preset application, the dependency relationship among codes can be better improved, the maintenance cost of the codes is reduced, abnormal conditions such as the sound and the picture of the display equipment during the channel switching can be avoided, and the user experience is improved.

The process of display control in this embodiment will be described in detail below.

Fig. 5 illustrates a flow chart of a display control method in some embodiments. The embodiment of the application provides a display device, where the controller is configured to execute the display control method described in fig. 5, including:

step 501, a preset application receives a split screen display message sent by a controller; the split screen display message comprises a target split screen template identifier.

The preset application refers to an application installed when the display equipment leaves the factory, and can be used for switching between applications and channels, so that shielding processing can be conducted on a black screen, a screen flashing screen and the like, and mute processing can be conducted on a pop sound and the like.

Specifically, in any scenario, the user may send the split-screen display message by pressing a shortcut key on a controller (such as a remote controller), so that a preset application of the display device may receive the split-screen display message sent by the controller.

Further, the target split screen template identification is obtained by analyzing the split screen display message; the target split-screen template identifier can uniquely identify a target split-screen template, for example, the target split-screen template corresponding to the target split-screen template identifier 1 is a 'split-screen film', and the target split-screen template corresponding to the target split-screen template identifier 2 is a 'double-path screen projection'.

Step 502, matching is carried out in a setting database according to the target split screen template identification, and target template binding information is obtained; the target template binding information comprises a target starting mode, a target starting value and a target channel identifier.

The split screen template identification and the binding information are stored in the setting data in a correlated mode (a mapping mode and the like) in advance, so that matching can be carried out in the setting database according to the target split screen template identification, and the target template binding information is obtained.

The target template binding information comprises a target starting mode, a target starting value and a target channel identifier; the target starting modes can be "service", "activity", and "receiver", and represent starting through startService (), startActivity (), sendbar () modes respectively, for notifying the multi-window portal application to start the corresponding split screen template; the target starting value is a starting mode of the multi-window portal application and simultaneously comprises a split screen template type value, wherein the split screen template type value is a unique identifier of the split screen template; the target channel identification is used to uniquely identify a channel.

Specifically, the target split screen template identification is obtained, matching is carried out in a setting database, and corresponding target template binding information such as a target starting mode, a target starting value, a target channel identification and the like is obtained.

And step 503, when the current channel is judged to be different from the target channel corresponding to the target channel identifier, switching the current channel to the target channel, and sending the target starting value to the multi-window portal application in a target starting mode.

In the embodiment of the application, after target template binding information such as a target starting mode, a target starting value and a target channel identifier is acquired, a target channel is determined according to the target channel identifier, a subsequent operation is performed according to whether a current channel is identical to the target channel or not, more specifically, when the current channel is different from the target channel corresponding to the target channel identifier, a preset application switches the current channel to the target channel, and the target starting value is sent to a multi-window portal application in the target starting mode.

It should be noted that, when the current channel is the same as the target channel corresponding to the target channel identifier, it means that channel switching is not required, and the target starting value may be directly sent to the multi-window portal application in a target starting manner.

Step 504, the multi-window portal application starts the target split screen template corresponding to the target split screen template type value in the target starting value and displays the target split screen template on the display.

In the embodiment of the application, after the multi-window portal application receives the target starting value, the target split-screen template type value in the target starting value is obtained, so that the target split-screen template corresponding to the target split-screen template type value is determined, and the target split-screen template is started to be displayed on a display.

In the above example, when the split screen template is started by the controller shortcut key, whether the current split screen template needs to be subjected to channel switching and the split screen template is started or not can be judged according to binding information in the database, and meanwhile, the channel switching is performed by the preset application.

Referring to fig. 6, fig. 6 is a schematic diagram of a structure of a display apparatus for implementing the display control method shown in fig. 5. The display device for implementing the display control method shown in fig. 5 may include: a receiving module 601, an acquiring module 602, a judging module 603, a transmitting module 604 and a starting module 605. The receiving module 601 is configured to preset that an application receives a split screen display message sent by the controller; the split screen display message comprises a target split screen template identifier; the obtaining module 602 is configured to match in the setting database according to the target split screen template identifier, and obtain target template binding information; the target template binding information comprises a target starting mode, a target starting value and a target channel identifier; a judging module 603, configured to judge whether the current channel is the same as the target channel corresponding to the target channel identifier; a sending module 604, configured to switch the current channel to the target channel when the current channel is different from the target channel corresponding to the target channel identifier, and send the target start value to the multi-window portal application in a target start mode; the starting module 605 is configured to start the multi-window portal application and display, on the display, a target split-screen template corresponding to the target split-screen template type value in the target start value.

Fig. 7 illustrates a flow chart of another display control method in some embodiments. The present embodiment further optimizes the above display control method on the basis of the above embodiments. As shown in fig. 7, the method further includes:

in some embodiments of the present application, the multi-window portal application initiates the split screen template in response to initiation information sent by the controller.

In some embodiments of the present application, a menu key identification is received, and a determination is made as to whether the menu key identification is a bound key identification.

In some embodiments of the present application, the binding shortcut key hint information is displayed on the display in case the menu key identification is not a bound key identification.

In some embodiments of the present application, a confirmation message based on the binding shortcut key prompt message is received, and the menu key identifier and the split screen template are associated.

In some embodiments of the present application, a starting mode, a starting value and a channel identifier of a split screen template are set as binding information; and adding the split screen template type value of the split screen template into the starting value.

In some embodiments of the present application, the split-screen template identifier of the split-screen template is associated with the binding information and then stored in the setting database.

In this embodiment of the present application, a split screen template is first started through a multi-window portal application, a shortcut key binding operation is defined under the split screen template by pressing a menu key, for example, after pressing a menu key a, whether the menu key a is bound is determined, if not, the started split screen template can be bound, and after confirming the binding, the setting database is written.

Specifically, the user sends the start information through a controller (such as a remote controller), so that after the multi-window portal application receives the start information, the split-screen template matched with the start information is started, as an example of a scene, the split-screen template a1 and the split-screen template a2 are displayed in the multi-window portal application of the display device, and the user sends the start information by clicking the display split-screen template a1 for confirmation, so that the multi-window portal application starts the split-screen template a1.

After the split screen template is started, a user can select one menu key to bind according to the requirement, so that the menu key identification can be received; and judging whether the menu key identification is the bound key identification or not in a mode such as whether the menu key identification comprises the binding identification or not.

Further, under the condition that the menu key identifier is not the bound key identifier, binding shortcut key prompt information is displayed on a display to prompt a user to bind the menu key identifier with the split screen template started before, so that after receiving confirmation information based on the binding shortcut key prompt information, the menu key identifier and the split screen template are subjected to association operation, namely, the split screen template can be started quickly through the pressing operation of the menu key corresponding to the menu key identifier, and the use requirements of different users are met.

Further, after the menu key identification and the split screen template are associated, binding information of the split screen template is required to be set, namely, a starting mode, a starting value and a channel identification of the split screen template are set as the binding information; and finally, the split screen template identification of the split screen template and the binding information are associated and then stored in a setting database.

Fig. 11 illustrates a flow chart of yet another display control method in some embodiments. The present embodiment further optimizes the above display control method on the basis of the above embodiments. As shown in fig. 11, the method includes:

In some embodiments of the present application, a split screen template identifier is set as a keyword, and binding information is set as an attribute value; the method comprises the steps of taking a starting mode as a first field of an attribute value, taking a starting value as a second field of the attribute value and taking a channel identifier as a third field of the attribute value; the split screen template type value is added into a second field; and storing the keywords and the attribute values in a setting database after associating.

Specifically, the split screen template identifier and the binding information are written into the setting database in the form of keywords and attribute values, wherein the keywords are the split screen template identifiers, and the attribute values are the binding information definition formats: the first field #second field #third field, split by "#" sign; specifically, the first field indicates the start mode: the values may be "service", "activity", "receiver", and represent starting by startService (), startActivity (), sendloadcast () respectively, for notifying the multi-window portal application to start the corresponding split screen template. The second field represents a start value, which can be converted into a character string by "intent (0)", and converted into a start value by "intent (0)", wherein the start value is a start mode of the multi-window portal application, and also contains a type value of the split screen template bound by the current shortcut key, and the type value is a unique identifier of the split screen template. The third field is an optional field, which represents whether the signal source channel needs to be cut, and if so, a corresponding channel identifier can be written; writing "-1" if no channel cut is required; if this field is not written, the android channel will be cut by default.

In some embodiments, when the current channel is judged to be the same as the target channel corresponding to the target channel identifier, the target starting value is sent to the multi-window portal application in a target starting mode.

Specifically, the same indication of the current channel and the target channel corresponding to the target channel identifier indicates that the channel is not required to be switched, and the target starting value is directly sent to the multi-window entry application in a target starting mode.

In some embodiments, when the target channel is identified as the target value, the target startup value is sent to the multi-window portal application by a target startup mode.

Specifically, when the target channel is identified as the target value, for example, when the target channel is in a '1' state, the split screen template can be displayed in any channel, and the target starting value can be directly sent to the multi-window portal application in a target starting mode.

In some embodiments, the target channel is determined to be the first channel when the target channel identification is empty, and the current channel is switched to the first channel when the current channel is not the first channel.

Specifically, when the target channel identifier is empty, the android channel is cut by default, so that the target channel is the first channel, namely the android channel, and when the current channel is not the android channel, the current channel is switched to the android channel.

As an example of a scenario, as shown in fig. 12, step 12.1 starts a split screen template; step 12.2, binding the split screen template to the shortcut key by pressing a menu key; step 12.3, judging whether the menu key is already bound; step 12.41, if not, popping up a user binding shortcut key prompt; step 12.42, if yes, popping up a prompt for releasing the shortcut key binding from the user; step 12.5 binding/unbinding by pressing the confirm key, updating the setting database data.

Specifically, a split screen template is started through a multi-window portal application, shortcut key binding operation is defined under the split screen template, after a menu key is pressed, whether the menu key is bound or not is judged, if not, the split screen template is started through binding, and after the binding is confirmed, a setting database is written; and if the setting data is already bound, unbinding the split screen template, and clearing the setting data. When the split screen template binds the shortcut key, the current split screen template writes the binding information into the setting database in the form of key-value key value pairs.

Therefore, when the multi-window split screen template binds the shortcut key, binding information is recorded in the setting database, so that when a user starts the multi-window split screen template through the shortcut key of the remote controller, whether the current split screen template needs channel switching and starting of the split screen template is judged according to data information stored in the setting database, and the problems of channel switching and abnormal display of the split screen template in the process of jumping through the shortcut key of the controller are solved.

Fig. 13 illustrates a flow chart of yet another display control method in some embodiments. The present embodiment further optimizes the above display control method on the basis of the above embodiments. As shown in fig. 13, the method includes:

in some embodiments of the present application, when the target channel is the first channel, the screen area of the display is divided into two screen sub-areas, and two different application interfaces are respectively displayed in the two screen sub-areas.

In some embodiments of the present application, the target channel is a second channel, display area window information corresponding to the second channel is obtained, a first multimedia information stream of the first signal is displayed in a display area corresponding to the first channel, a target window is created in a display area corresponding to the first channel, and the second multimedia information stream of the second signal is output to the target window according to the display area window information according to a preset display form.

Specifically, the user starts the process of binding the split screen template through the shortcut key of the remote controller. In the switching process of the signal source channels, abnormal scenes such as black screens, audio popping and switching failure can occur, and the whole machine preset application (which can be used for application and switching among the signal source channels) can perform shielding treatment on the black screens, the popping screens and the like and perform mute treatment on the popping sounds and the like. The present application thus performs channel switching through a preset application.

As an example of a scenario, as shown in fig. 14, step 14.1 starts a split screen template by pressing a shortcut key of a remote controller in any scenario; step 14.2, displaying that a preset application (such as a transition application) in the device receives a shortcut key broadcast notification; step 14.3, analyzing the information of the setting database; step 14.4, judging whether the channel needs to be switched or not; if yes, executing the step 14.5 to switch the preset application to the corresponding signal source channel, and then executing the step 14.6; if step 14.6 is not performed, the multi-window portal application is notified to launch the bound split screen template.

Specifically, a user presses a shortcut key of a remote controller to start a bound split screen template under any scene, after receiving a key broadcast notification, a preset application analyzes data information stored in a setting database before analyzing, and obtains a physical channel on which the current split screen template depends through a third field (channel identifier) of a value (attribute value). If the physical channel of the split screen template is inconsistent with the channel of the current display device, switching the signal source channel by a preset application; if the current channel identifier is-1, the current split screen template does not need to switch channels. And then the preset application transmits the content (starting) value of the second field to the multi-window portal application through the first field of the value, and the multi-window portal application starts the corresponding split-screen template according to different split-screen template type values (type values).

Specifically, the android channel lower split screen mode is that the system splits the screen into two areas and then displays two different applications respectively. Unlike android channels, the split screen display of source under physical channels is that the system creates a transparent window above the current channel according to the position and size of the window of the display area of the physical channels so as to achieve the hole digging effect, and then outputs the video stream under the physical signals to the corresponding position according to the position and size of the window.

In the above embodiment, when the multi-window split screen template binds the shortcut key, the binding information is recorded in the setting database, so that when the user starts the multi-window split screen template through the shortcut key of the remote controller, whether the current split screen template needs to perform channel switching and starting of the split screen template is judged according to the data information stored in the setting database, and meanwhile, the channel switching is performed by means of the existing preset application. The dependency relationship among codes can be better improved, and the maintenance cost of the codes is reduced.

Based on the description of the foregoing embodiment, the "two-way screen-throwing" is to simultaneously display the screen-throwing content of two mobile phones on the display device side such as a television, and because the HDMI channel and the Android channel are two different audio/video interfaces for different audio/video transmission, if the "two-way screen-throwing" template is opened under the HDMI channel, the audio playing under the HDMI channel will not be terminated at this time, so that the current channel needs to be switched to the Android channel under the scene. However, due to the limitation of the decoding bandwidth of the device, when the multi-window template and the switching channel are started to be performed simultaneously, a scene that multiple paths of videos are played simultaneously exists, and the switching process is blocked, a black screen is blocked, the audio playing is not stopped in time, and the like.

It can also be understood that the "hdmi+single-pass screen-drop" template is to display the HDMI channel content and the mobile phone screen-drop content on the same interface, so when the user starts the template through the remote control shortcut key and the current device is in the Android channel, the current channel needs to be switched to the HDMI channel. However, if the source is switched again at the start of the template, a short black screen will appear during the start-up process due to the time consuming channel switching.

The embodiment of the application provides a display control method, when a shortcut key starts a multi-window template, if channels need to be switched, the channels are switched in advance through preset application, so that abnormal conditions are avoided.

As an example of a scenario, as shown in fig. 15, step 15.1 remote control shortcut binds a multi-window template; step 15.2, pressing a shortcut key of a remote controller under any scene to start a multi-window template; step 15.3, the preset application receives the key notification to acquire and analyze the database information; step 15.4, judging whether the signal source channel needs to be switched or not; if yes, executing step 15.5 to switch to the corresponding signal source channel; if not, step 15.6 is performed to inform the multi-window portal application to launch the bound multi-window template.

Specifically, a user presses a shortcut key of a remote controller to start a bound multi-window template; the preset application in the display equipment receives the key notification, and acquires and analyzes the database data set according to the rule; judging whether to switch signal source channels at present; if the switching of the signal source channel is required, switching to a corresponding channel according to the channel identification of the third field of the database; if the switching of the signal source channel is not needed, the next step is directly carried out; after the preset application executes the channel switching operation, the multi-window entry application is notified, and the multi-window template is started. The starting mode is information of a first field and a second field obtained from a database.

Therefore, when the shortcut key is bound to the multi-window split screen template, the template information is recorded in the setting database, when a user starts the multi-window split screen template through the shortcut key of the remote controller, if the channel needs to be switched at this time, the whole machine preset application is firstly informed to switch the channel, then the preset application is informed to start the corresponding split screen template through the multi-window portal, and if the channel does not need to be switched, the multi-window portal application is informed to start the multi-window split screen template through the preset application. Therefore, the embodiment of the scheme can shorten the overall starting time and avoid the abnormal conditions of screen blackout and the like caused by simultaneous switching.
