FIG. 8 illustrates a block diagram of a dual screen display device according to some embodiments. In order to implement the split-screen display of the media asset file and improve the user experience, an embodiment of the present invention provides a display device, which is applied to a display device of a dual-screen single system, and referring to fig. 8, the display device 200 includes: a first display 201 configured to present a first user interface in which content of applications, messages or assets is presented; a second display 202 configured to present a second user interface in which system messages, notifications, or media asset information, etc. are presented; and the controller is connected with the first display and the second display and is configured to execute the media asset file split screen display method.

FIG. 9 illustrates a flow diagram of a method for split-screen presentation of a asset file, according to some embodiments; figure 10 illustrates a data flow diagram of a method for split-screen presentation of a asset file, according to some embodiments. An embodiment of the present invention provides a display device, which may be a dual-screen single-system display device, and when the method for displaying a media asset file in a split screen manner shown in fig. 9 and 10 is executed, a controller is configured to execute the following steps:

and S11, responding to the operation of triggering the display of the media asset file, generating a first message needing to be displayed in the first display and a second message needing to be displayed in the second display, wherein the first message is used for representing the media asset content of the media asset file, and the second message is used for representing the media asset information of the media asset file.

When the display equipment is needed to be used for displaying the media asset files, a user can click and designate the media asset files in a remote controller or voice mode, and the media asset files can be video files needing to be played and can also be files for displaying pictures.

In some embodiments, when the media asset file needs to be displayed, a media asset acquisition request can be sent to the server through the large-screen application, and the server issues the corresponding specified media asset file. The large screen application refers to an application that the asset file is to be displayed when being started, and the asset content is to be displayed on the first display (large screen).

And after receiving the specified media asset file returned by the server, judging whether double-screen display is needed or not according to the service scene. And obtaining the system attribute of the display equipment, and if the system attribute represents that the home terminal is the double-screen display equipment and the specified media asset file comprises media asset content and media asset information, determining that the specified media asset file needs double-screen display.

When a user triggers a certain appointed media asset file, a first message needing to be displayed in the first display and a second message needing to be displayed in the second display can be synchronously generated, and the first display or the second display can conveniently display the content according to the corresponding messages. And, the generated first message is different and the second message is different according to different application scenarios.

In some embodiments, when the asset file is a video file, the controller is further configured to, in performing generating a first message to be presented in the first display and a second message to be presented in the second display:

step 1111, in response to the operation of triggering the video file playing, acquiring the video content and the video information of the video file.

Step 1112 generates a first message to be presented on the first display based on the video content and generates a second message to be presented on the second display based on the video information.

When video playing needs to be performed by using the display device, a video list comprising different video files is presented in a first user interface of the first display, and a user can trigger a certain video file in the list to be played in a remote controller or a voice mode.

FIG. 11 illustrates a schematic diagram of presenting a list of videos in a first user interface, according to some embodiments. After the user starts the display device, the homepage of the display device presents a user interface, and the user interface comprises different types of applications such as my, recommendation, list, special subject, movie and television, games and the like. If the user wants to view the movie-like resource, then "movie" is triggered, and a list of videos is presented in the user interface. Referring to fig. 11, the video list includes a plurality of different video files, such as "daddy", "all are good", "jadeite", etc., the user triggers the "daddy" video file in the list through a remote controller or a voice mode, and the controller obtains the video content and the video information of the video file from the server.

In order to improve the experience of a user, the double-screen display equipment can realize the split-screen display of the video file. Since the viewable area of the first display is larger than the viewable area of the second display, the video content is presented on the first display and the video information is presented on the second display.

Therefore, the playing operation of the user on the specified video file is received, and the video content and the video information of the video file are acquired from the server side. In this case, the video content is content to be displayed on the first display, and the video information is content to be displayed on the second display.

The video information comprises information such as a progress bar, a video name and a video set number, and the video content is a video picture of the video file. In order to avoid shielding the video picture, the video information needs to be sent to the second display for displaying, and the video content needs to be sent to the first display for displaying. Therefore, a first message is generated based on the video content, and the first display responds to the first message to display the video content. And generating a second message based on the video information, the second display responding to the second message to display the media information.

In some embodiments, during the playing of a certain video file, a recommendation medium may also be generated according to the face of a certain actor appearing in the video frame, so as to be pushed to the user. Accordingly, the controller is further configured to:

and 1113, when the first display plays the video content, if the playing picture of the first display has the image of the designated person, performing media asset search based on the designated person to obtain media asset push information including the designated person.

Step 1114, generating a second message to be presented on the second display based on the asset push information including the designated persona.

In order to realize the media asset recommendation process, the designated persons capable of executing media asset recommendation can be preset, namely, the media asset push information is generated only according to the designated persons, and the media asset push information is not generated for other persons.

When the first display plays video content, people appearing in a playing picture are detected in real time, if the appearing people are designated people, media asset searching is carried out based on the designated people, and all media assets in which designated tasks participate are generated into media asset pushing information. For example, when a "all good" video file is played, if an image of "yaohao" appears in the video screen, a resource search may be performed based on the image of "yaohao", and a movie resource related to "yaohao" is pushed to the user.

In order to avoid shielding original displayed content in the first display when the media asset push information is displayed, the media asset push information can be sent to the second display for displaying, and at the moment, a second message needing to be displayed on the second display is generated based on the media asset push information comprising the designated figure.

In some embodiments, after the video file is played in the vicinity of the video file, a file similar to the video file may be generated to be pushed to the user. Thus, when the asset push during the playing of the video file generates a second message requiring content presentation on the second display, the controller is further configured to perform the steps of: when the video file is played, if the playing time length of the video file meets the pushing time condition, generating the post-simulcast information based on the video file; based on the post-simulcast information, a second message is generated that needs to be presented on a second display.

When the dual-screen display device is used for playing the video file, if the video file is close to the playing completion time, for example, the playing time of the video file meets the pushing time condition, the post-simulcast information can be generated based on the video file. The push time condition refers to a time condition for pushing the video resource, and in some embodiments, the push time condition may be set to the first 30 seconds of the overall duration of the video file, that is, the last 30 seconds after the video file is played, and the post-simulcast information may be generated according to the currently played video file.

In some embodiments, when the asset file is a drawing file, the controller is further configured to, in performing generating a first message to be presented in the first display and a second message to be presented in the second display:

step 1121, responding to the operation of triggering the display of the drawing file, and acquiring the drawing content and the drawing information of the drawing file.

Step 1122 generates a first message to be presented on the first display based on the drawing content, and generates a second message to be presented on the second display based on the drawing information.

When the display device is required to be used for displaying the painting, a painting list comprising different painting files is displayed in a first user interface of the first display, and a user can trigger a certain painting file in the list to be displayed in a remote controller or a voice mode. The presentation form of the drawing list may be the same as that of the video list shown in fig. 11, and is not described herein again.

In order to improve the experience of a user, the double-screen display equipment can realize the split-screen display of the drawing file. At the moment, the display device receives the playing operation of the user on the appointed drawing file, and obtains the drawing content and the drawing information of the drawing file from the server side. In this case, the drawing content is the content to be displayed on the first display, and the drawing information is the content to be displayed on the second display.

The painting information includes the name of the painting, the author of the painting, the brief introduction of the painting, and the like, and the painting contents are the painting itself, such as painting works, photographic works, and the like. In order to avoid shielding the drawing content, the drawing information needs to be sent to the second display for displaying, and the drawing content is sent to the first display for displaying. Therefore, a first message is generated based on the drawing content, and the first display responds to the first message to display the drawing content. And generating a second message based on the painting information, the second display responding to the second message to display the painting information.

In some embodiments, the second message generated to be displayed on the second display during the display of the video file or the drawing file may also be a notification service type message automatically triggered by the system, for example, a message generated when the device fails, a message generated when a weather warning is received, a message generated when an alarm clock set by the user reaches a set time point, a message generated by message information or chat information sent by other users, and the like.

In some embodiments, after different first messages and second messages are generated in different service scenarios, the first messages are sent to a first display, so that media asset information corresponding to the first messages is displayed by the first display; and sending the second message to a second display so that the second display displays the media asset information corresponding to the second message.

And S12, if the second display does not display the prior message, displaying the media information corresponding to the second message in the second display, and displaying the media information content corresponding to the first message in the first display.

When the second message is sent to the second display so that the second display displays the media asset information corresponding to the second message, the second display can display different types of messages, namely the media asset information corresponding to the media asset content and service notification type information generated by the system.

Then, if the second display receives the media asset information or the service notification information during the process of displaying the media asset information, the second display cannot determine whether to display the newly received information or continue to display the original information.

Therefore, after receiving the second message, the second display needs to first determine whether the information is displayed in the second display. If the second display does not display the previous message, the second display can directly display the content corresponding to the second message, that is, the media information corresponding to the second message is displayed in the second display. And simultaneously, displaying the media asset content corresponding to the first message in the first display.

In some embodiments, the previous message refers to media information or service notification type information that is presented before the second display, and the previous message does not include information that is presented by default on the second display, such as date, time, volume, number of messages, and the like.

If the second display displays the previous message, the priority order of the previous message and the second message needs to be judged to determine the display content of the second display.

FIG. 12 illustrates an effect diagram of a dual screen display device presenting a video file, according to some embodiments. Referring to fig. 12, in some embodiments, when a user triggers a "dad" video file by means of a remote controller or voice while a video file is being presented using a dual-screen display device, the episode content of "dad" is presented on a first display. If the second display did not show the previous message, then the video information of "dad (progress bar, video name, video set number, etc.) is shown on the second display.

FIG. 13 illustrates a diagram of a dual screen display device showing the effects of a paint file, according to some embodiments. Referring to fig. 13, in some embodiments, when the painting file is displayed by using the dual-screen display device, the user triggers the "sunrise and moonnight" painting file through a remote controller or by voice, and the contents of the "sunrise and moonnight" painting are displayed on the first display. And if the second display does not display the prior message, displaying the painting information (information such as painting name, painting author and the like) of 'star night and moon' on the second display.

S13, if the second display displays the prior message, the content corresponding to the designated message is displayed in the second display according to the priority order of the second message and the prior message, the content corresponding to the designated message comprises the media asset information corresponding to the second message and the prior content corresponding to the prior message, and the media asset content corresponding to the first message is displayed in the first display.

If the second display displays the previous message, that is, the second display receives the media asset information or the service notification information in the process of displaying the media asset information, the display content of the second display can be determined according to the priority order of each message, so that the display content of the second display can be determined.

The priority of different messages is pre-configured by the system, messages with high priority can be responded to with priority, and messages with low priority can be responded to with delay or not. Under normal conditions, the priority of equipment failure type messages is highest, the priority of weather early warning type messages and alarm clock reminding type messages is next, the priority of messages leaving messages or chatting type messages is next, the priority of recommendation type messages is next, and the priority of video (drawing) information type messages is lowest.

After the first message and the second message are generated, the media asset content corresponding to the first message is displayed in the first display. And the second display judges the priority order of the second message and the prior message first, and further determines the content of the designated message which can be displayed. The content of the designated message can be the media information corresponding to the newly received second message and can also be the prior content originally displayed.

In some embodiments, the controller, in performing presenting content corresponding to the specified message in the second display according to a priority order of the second message with the previous message, is further configured to:

and step 131, determining the priority order of the media asset information and the prior message according to the priority attribute carried by the second message and the priority attribute carried by the prior message.

And 132, if the priority of the second message is higher than or equal to that of the prior message, displaying the media information corresponding to the second message in the second display.

And step 133, if the priority of the second message is lower than that of the previous message, not displaying the media information corresponding to the second message in the second display, and displaying the previous content corresponding to the previous message in the second display.

And when the priority of the second message is compared with the priority of the previous message, acquiring the priority attribute carried by the second message and the priority attribute carried by the previous message, wherein the priority attribute is used for representing the priority level of the corresponding message. Based on the priority attributes of the two messages, the priority order of the media asset information and the prior message can be determined.

In some embodiments, if the priority of the second message is higher than or equal to the priority of the previous message, it is indicated that the second message can be responded to, and its corresponding asset information can be presented. At this time, the media asset information corresponding to the second message is displayed in the second display, that is, the second display displays the content corresponding to the new message, and the display content is switched from the previous content to the media asset information corresponding to the second message.

In some embodiments, if the priority of the second message is lower than the priority of the previous message, it indicates that the second message cannot be responded, and the corresponding media information cannot be displayed. At this time, the media information corresponding to the second message is not displayed in the second display, and the original content, that is, the previous content corresponding to the previous message is still displayed in the second display.

In some embodiments, the second display presents content corresponding to messages of high priority and does not present content corresponding to messages of low priority.

In some embodiments, the replacement of the presentation content is also performed when the priority of the two messages is consistent. For example, if the user previously watched the drawing a, the first display shows the content of the drawing a, and the second display shows the information of the drawing a; and if the user views the painting B again, the first display displays the content of the painting B, and the priority of the information of the painting B is consistent with that of the information of the painting A, the second display performs content replacement, namely displays the information of the painting B.

In some embodiments, different message types need to be presented for different durations, for example, a message of a video progress bar type needs to be presented continuously during playing of a video file, while a message of a service notification type only needs to be presented for a certain period of time, and the presentation is cancelled after the user is predicted to have finished viewing the message. Based on this, the messages can be divided into short-time messages and long-time messages according to the display duration requirement.

The transient message refers to a message with the display duration meeting the duration requirement, such as a service notification message, the transient message does not need to be displayed all the time, the display can be cancelled after the duration requirement is met, and at the moment, the second display resumes displaying the original content. The long-life type message refers to a message needing to be continuously displayed, such as a video progress bar and the like.

In some embodiments, in the case that the priority of the second message is higher than the priority of the previous message, or the priority of the second message coincides with the priority of the previous message, the controller is further configured to:

step 1321, when the media information corresponding to the second message is displayed in the second display, determining the message type of the second message according to the type identifier carried by the second message.

Step 1322, if the type identifier of the second message represents the transient type message, canceling the display of the media asset information when the display duration of the media asset information in the second display exceeds a first preset duration, and displaying the previous content corresponding to the previous message in the second display.

And 1323, if the type identifier of the second message represents the permanent type message, canceling the display of the previous content corresponding to the previous message, and displaying the media information corresponding to the second message in the second display in a replacement manner.

And under the condition that the priority of the second message is higher than that of the prior message or the priority of the second message is consistent with that of the prior message, the media asset information corresponding to the newly received second message can be displayed in the second display. At this time, in order to determine the presentation form of the media asset information corresponding to the second message, the type identifier carried by the second message may be acquired to determine the message type of the second message.

In some embodiments, if the type identifier of the second message indicates that the message is an ephemeral type message, it indicates that the message only needs to be ephemeral. Therefore, the display time of the second display in displaying the medium resource information is counted. And if the display time of the media asset information in the second display exceeds the first preset time, indicating that the display needs to be resumed, namely canceling the display of the media asset information, and displaying the prior content corresponding to the prior message in the second display.

In some embodiments, the first preset time period may be set to 15 seconds, or may be set to other values according to practical applications, and is not limited herein. When the display time of the media asset information displayed in the second display exceeds 15 seconds, the second display (small screen) is restored to the original display state, namely, the originally displayed content is continuously displayed.

In some embodiments, when a video file is presented using a dual screen display device, the content presented in the dual screen display device is as shown in FIG. 12. For example, a user triggers a "dad" video file by means of a remote controller or voice, and then shows the episode content of "dad" on a first display. And showing the video information (progress bar, video name, video set number and the like) of the 'dad' on the second display. It can be seen that the previous message in the second display is video information, the priority level is lowest, and the displayed progress bar is a long-term message.

If in the process of playing the video file, messages or chatting messages are generated, such as the messages sent by summer arbor. It can be known that the priority of the message or the chat message is higher than that of the video information, so that the second display is required to display the message or the chat message.

FIG. 14(a) illustrates an effect diagram of a second display showing an ephemeral-like message, in accordance with some embodiments. Referring to fig. 14(a), when other users send messages to the home user in summer, rain, and george, the messages do not directly display the content, but first display a prompt message, such as "you have a new message". If the user at the end needs to check the details of the message, a menu key of the remote controller is triggered according to the operation prompt displayed on the right side of the second display, so that the message is checked. At this time, the prompt content corresponding to the message or the chat message is displayed in the second display, and the episode content of "dad" is still displayed in the first display.

FIG. 14(b) illustrates another effect diagram of the second display presenting an ephemeral-like message, in accordance with some embodiments. Referring to fig. 14(b), if the user wants to view the prompting message in the second display, the menu key of the remote controller is triggered to obtain the specific content corresponding to the prompting message, such as the message "summer rain joe: today overtime, without returning to eat, you eat … "and show that particular content in the second display, while still showing" dad's "episode content in the first display.

Because the message or the chat message is a transient message, the message is only displayed transiently. Therefore, when the second display starts to display the messages or the chat messages, the display duration of the messages or the chat messages is counted. When the display duration exceeds the first preset duration (15 seconds), the second display cancels the display of the messages or the chat messages, and the second display (small screen) restores to the original display state, namely, the video information of dad continues to be displayed. The effect of the recovery state is shown in fig. 12.

In some embodiments, in the case that the priority of the second message is higher than that of the previous message, or the priority of the second message is consistent with that of the previous message, the second display may display the asset information corresponding to the newly received second message. If the type identifier of the second message indicates that the message is a long-time type message, the message needs to be continuously displayed. Therefore, the display content of the second display needs to be completely switched, a display recovery process is not needed, namely, the display of the previous content corresponding to the previous message is cancelled, and meanwhile, the media information corresponding to the second message is displayed in the second display in a replacement mode.

In some embodiments, when a paint file is presented using a dual-screen display device, the content presented in the dual-screen display device is as shown in FIG. 12. In some embodiments, when the user triggers the drawing file of "star moon night" by means of a remote controller or voice while the drawing file is displayed by using the dual-screen display device, the contents of the drawing of "star moon night" are displayed on the first display. And displaying the painting information (information such as painting name, painting author and the like) of the 'star night and moon' on the second display. It can be seen that the previous message in the second display is the drawing information, with the lowest priority.

If the user starts a certain video file to play in the process of displaying the drawing file, the generated message is the video information comprising the progress bar. The priority of the video information is consistent with that of the drawing information, content replacement display can be carried out, namely the video information is displayed in the second display, and meanwhile, after media asset switching is carried out, the video content is switched and displayed in the first display.

Since the video information including the progress bar is a long-term type information, it needs to be continuously displayed. Therefore, the display content in the second display needs to be replaced completely, that is, the originally displayed painting information is canceled from being displayed, and meanwhile, the next video file is displayed in the second display where the video information is continuously displayed. The replaced two-screen display content may be as shown in fig. 12.

In some embodiments, the content presented in the second display may determine whether the message may be presented according to a message priority, and determine a presentation form of the message according to a message type.

In some embodiments, when the previous content displayed in the second display is video information, if the second message represents the asset recommendation information, the display content of the second display is switched from the video information to the asset recommendation information, and when the display duration of the asset recommendation information exceeds a first preset duration, the display content of the second display is switched from the asset push information back to the video information.

Referring again to fig. 12, the user triggers "dad" video file by means of remote control or voice, and then shows the episode content of "dad" on the first display. And showing the video information (progress bar, video name, video set number and the like) of the 'dad' on the second display. It can be seen that the previous message in the second display is video information, the priority level is lowest, and the displayed progress bar is a long-term message.

FIG. 15 illustrates an effect of the second display showing media asset recommendation information according to some embodiments. Referring to fig. 15, in the process of playing a video file of "dad", if a specified character, such as an actor "article", appears in the played picture, media recommendation information, such as "article highlights, and love beans shots" are generated according to other movie works that the actor "article" shows.

The media asset recommendation information is recommendation type information, and the priority of the recommendation type information is higher than that of the video information, so that the media asset recommendation information can be displayed by the second display. At this time, the first display still shows the episode content of dad, and the second display does not show the video information such as progress bar, but instead shows the recommendation information of media assets, such as "wonderful article, enjoy loving beans shot".

Because the media asset recommendation information is a transient message, the short-term display is only needed. Therefore, after the display duration of the media recommendation information in the second display exceeds the first preset duration (15 seconds), the second display cancels the display of the media recommendation information, and the second display (small screen) restores to the original display state, namely, the video information of 'dad' is continuously displayed. The effect of the recovery state is shown in fig. 12.

In some embodiments, when the previous content displayed in the second display is video information, if the second message represents video information, the priority of the two information is the same, and content replacement can also be performed. At this time, the display content of the second display is replaced by the video information corresponding to the second message instead of the video information corresponding to the prior content.

For example, if a user plays a "dad" video file first, the first display shows the episode content of "dad", and the second display shows the video information (progress bar, video name, number of video episodes, etc.) of "dad". And then, if the video file which is 'good' is played again, the priority of the generated new video information is consistent with that of the original video information, and the new video information and the original video information are all long-term messages, the content of the second display can be replaced so as to display the next video file, and at the moment, the first display synchronously replaces the content. After replacement, the first display shows the episode content of the 'all-upright' episode, and the second display shows the video information of the 'all-upright'.

In some embodiments, after the video file is played in the vicinity of the video file, a file similar to the video file may be generated to be pushed to the user, that is, the generated simulcast information is sent to the second display for display. Referring again to fig. 12, the user triggers "daddy" video file by means of remote control or voice, and then shows the episode content of "daddy" on the first display. And showing the video information (progress bar, video name, video set number and the like) of the 'dad' on the second display.

Fig. 16 illustrates an effect diagram of the second display showing the post-lineup information according to some embodiments. Referring to fig. 16, in the playing process of the video file "dad", if the video file is close to the playing completion time, that is, 30 seconds before the playing of the video file is completed, the post-simulcast information generated according to the currently played video file is "summer health preserving wonderful move". The post-simulcast information is a recommendation-type message with a higher priority than the video information, so that the post-simulcast information is displayed in the second display, while the episode content of "daddy" is still displayed in the first display.

Since the post-simulcast information is a transient message, only transient display is needed. Therefore, after the display duration of the post-simulcast information in the second display exceeds the first preset duration (15 seconds), the second display cancels the display of the post-simulcast information, and the second display (small screen) recovers to the original display state, i.e. continues to display the video information of dad. The effect of the recovery state is shown in fig. 12.

The post-simulcast information refers to media assets recommended to the user to be displayed after the currently played video file is played. Because the post-simulcast information is the video resource pushed to the user, in order to facilitate the user to click the pushed video resource to play, an operation prompt can be synchronously popped up at the right side of the post-simulcast information display position to inform the user of corresponding operation, and the prompt content can be 'click a menu key to view'. The user can check the specific content of the summer health care wonderful invitation by triggering the menu key of the remote controller, and at the moment, the specific content of the summer health care wonderful invitation is switched and displayed in the first display.

In some embodiments, the drawing information may be a transient type message or a persistent type message. Specifically, the method can be determined according to system configuration, and if the drawing content needs to be viewed and the drawing information can be correspondingly viewed all the time, the drawing information can be configured into a long-term message. If the painting information needs to be correspondingly viewed only at the initial moment or in the process of viewing while the painting content needs to be viewed, the painting information can be configured into a transient message.

Therefore, the display device provided by the embodiment of the invention can display the media asset file in a split screen manner, can determine whether the message can be displayed according to the message priority when the second display displays the message, and can determine the display form of the message according to the message type, so that the mutual shielding of the media asset information and the media asset content is avoided, and meanwhile, other messages can be displayed without influencing the display content of the first display in the display process of the media asset file, so that a user can continuously check the display content of the first display, and the user experience is good.

When the display device provided by the foregoing embodiment executes the method for displaying the media asset file in a split screen manner, the method is applied to a display device of a dual-screen single system, and both displays are controlled by a general controller, that is, the process of displaying the content by the first display and the second display is controlled by the general controller.

In other embodiments, the display device may also be a dual-screen dual-system display device, i.e., the first controller controls the display of each content in the first display and sends a broadcast to the second controller to inform the second controller to control the second display to display the content. In the dual-screen dual-system display device, a first controller is a main controller, a second controller is an auxiliary controller, a message needing to be displayed in a second display is generated in the first controller, the first controller sends the message to the second controller, and the second controller controls the second display to display.

Fig. 17 illustrates a business timing diagram of a method for split-screen presentation of a asset file according to some embodiments. Referring to fig. 17, the asset file to be displayed is triggered by an application (large screen application) configured in the first controller, and the large screen application acquires the specified asset file from the server and generates a first message to be displayed in the first display and a second message to be displayed in the second display.

In a scene of performing the dual-screen display, the first controller needs to send the second message to the second controller, so that the second controller determines whether to display the content corresponding to the second message according to the display state of the second display, and determines a display form, such as transient display or continuous display, of the content corresponding to the second message according to the scene.

In some embodiments, when sending the second message, a hiprp (dual screen information relay channel) is configured in the first controller, and the first controller forwards the second message to the second controller through the hiprp.

In some embodiments, an embodiment of the present invention provides a display device, including: a first display configured to present a first user interface in which content of applications, messages, or assets is presented; a second display configured to present a second user interface in which system messages, notifications, or media asset information, etc. are presented; a first controller connected with the first display, the first controller configured to: responding to an operation of triggering the display of the media asset file, and generating a first message needing to be displayed in a first display and a second message needing to be displayed in a second display, wherein the first message is used for representing the media asset content of the media asset file, and the second message is used for representing the media asset information of the media asset file; and displaying the media asset content corresponding to the first message in a first display, and sending the second message to a second controller so that the second controller displays the media asset content corresponding to the second message. And the second controller is connected with the second display and is configured to execute the media asset file split screen display method.

FIG. 18 illustrates another flow diagram of a method for split-screen presentation of a asset file, according to some embodiments. The display device provided in the embodiment of the present invention may be a dual-screen dual-system display device, and when the method for displaying a media asset file in a split screen manner shown in fig. 18 is executed, the second controller is configured to execute the following steps:

s21, receiving a second message sent by the first controller, and determining whether a previous message is displayed in the second display.

S22, if the second display displays prior messages, displaying the content corresponding to the designated message in the second display according to the priority order of the second message and the prior messages, wherein the content corresponding to the designated message comprises the media asset information corresponding to the second message and the prior content corresponding to the prior messages.

S23, if the second display does not display the prior message, displaying the media information corresponding to the second message in the second display.

In the dual-screen dual-system display device, since the first controller is the main controller, a message to be displayed on the first display and a message to be displayed on the second display are both generated in the first controller.

When the split-screen display is realized, the first controller displays the media asset content corresponding to the generated first message in the first display, meanwhile, the first controller sends the generated second message to the second controller, and the second controller judges whether the content is displayed in the second display after receiving the second message.

If the prior message is displayed, determining the priority order of the prior message and the newly received second message, and if the priority of the second message is higher than or equal to that of the prior message, displaying the media information corresponding to the second message in a second display; if the priority of the second message is lower than the priority of the prior message, the prior content corresponding to the prior message is presented in the second display. And if the second display does not display the prior message, the media information corresponding to the second message can be directly displayed in the second display.

In some embodiments, a first message and a second message are generated by a first controller, the first controller presents media asset content corresponding to the generated first message in a first display, and simultaneously, the first controller sends the generated second message to a second controller. The second controller determines whether a prior message, a priority order of the second message and the prior message, and a message type of the second message are shown in the second display. The specific execution processes of the first controller and the second controller can refer to the execution processes of the dual-screen single-system display device in the foregoing embodiments, and details are not repeated here.

Therefore, when the double-screen display equipment is used, a user selects the media asset file for display through the content displayed by the first display (large screen) after starting up, and sends the generated first message to the first display so as to display the media asset content on the first display; the generated second message is sent to the second controller. The second controller determines the display content of the second display according to the priority order of the new message and the previous message after receiving the large-screen message. When the message is displayed, whether the message is displayed continuously or transiently is determined according to the type of the message, and the display process is automatically performed without user intervention. The process can be applied to a double system or a single system, and the only dependent scene is the display equipment needing the content split-screen display, namely the double-screen display equipment.

According to the technical scheme, when the display device provided by the embodiment of the invention executes the method for displaying the media asset files in a split screen manner, the media asset files are triggered to be displayed, and the first message and the second message are generated. Displaying the media asset content corresponding to the first message on a first display, and displaying the media asset information corresponding to the second message on a second display when the prior message is not displayed in the second display; when a preceding message is presented in the second display, the content of the corresponding preceding message or second message of high priority is presented in the second display. Therefore, the display device provided by the embodiment of the invention can display the media asset file in a split screen manner, and determine whether the message can be displayed according to the message priority when the second display displays the message, so that the media asset information and the media asset content are prevented from being shielded, and meanwhile, the newly generated second message can be displayed on the second display without influencing the display content of the first display in the process of displaying the media asset file, and the user experience is good.
