As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display driver, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (like fingerprint sensor, temperature sensor, pressure sensor etc.) and power drive etc..

FIG. 6 illustrates an icon control interface display of an application in display device 200, according to some embodiments. In some embodiments, the display device may directly enter the interface of the preset vod program after being activated, and the interface of the vod program may include at least a navigation bar 510 and a content display area located below the navigation bar 510, as shown in fig. 6, where the content displayed in the content display area may change according to the change of the selected control in the navigation bar. The programs in the application program layer can be integrated in the video-on-demand program and displayed through one control of the navigation bar, and can also be further displayed after the application control in the navigation bar is selected.

In some embodiments, the display device may directly enter a display interface of a signal source selected last time after being started, or a signal source selection interface, where the signal source may be a preset video-on-demand program, or may be at least one of an HDMI interface, a live tv interface, and the like, and after a user selects different signal sources, the display may display contents obtained from different signal sources.

In some embodiments, when the video file is played by using the display device, the video file includes video content and video information, and the video information is profile information of the video content, including a video name, a progress bar, a collection number, and the like. Because the existing display equipment is only provided with one display, the video content and the video information need to be displayed at the same time in order to facilitate a user to synchronously view the video information when viewing the video content.

During the playing of the video file, in order not to obscure the main viewing content, the video progress bar is usually displayed at the beginning of the playing and is automatically hidden if there is no operation in 5 s. Therefore, the user cannot always view the video progress bar, so that the user cannot know the real-time playing progress of the video file, and if the user wants to view the video file, the user needs to trigger the display of the video progress bar, so that the operation is complex, and the user experience is influenced.

Therefore, in order to improve user experience, when the video file is displayed by using the display device, the video content and the video information of the video file can be displayed in a split screen mode, at the moment, two displays need to be configured for the display device, and the double-screen display device is formed. The video content is displayed by one display, the video information is displayed by the other display, mutual shielding of the video content and the video information which need to be displayed is avoided, and the video progress bar can be displayed in the other display all the time.

In some embodiments, to improve the user experience, the display device may be configured with two displays, namely a first display and a second display, where the first display serves as a main screen (large screen) for displaying the display content of the corresponding application, such as video content; the second display is used as a secondary screen (small screen) and used for displaying the social ability, information prompt and other contents such as video information for the user, and in the video playing process, the video information is displayed in the second display all the time.

In some embodiments, both displays may be controlled by a single overall controller, and in this case, a single controller is configured in the display device to form a dual-screen single-system display device. The controller is in communication connection with the first display and the second display respectively, and content display of the two displays is achieved.

In some embodiments, the two displays may be respectively controlled by corresponding controllers, and in this case, the two controllers, namely the first controller and the second controller, are configured in the display device, so as to form a dual-screen dual-system display device. A first hardware system is configured in the first controller and is a main chip; and a second hardware system is configured in the second controller and is an auxiliary chip.

Fig. 7 illustrates a block diagram of a dual screen dual system display device according to some embodiments. Referring to fig. 7, the first controller 210 is connected to the first display 201, and the second controller 310 is connected to the second display 202. 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.

When a user operates the display device to generate a message or the device itself generates a message, the first controller sends the message to be presented in the second display to the second controller, so that the second controller presents the message in the second display. Namely, when the video content of the video file is played in the first display, the video information of the video file is sent to the second display for continuous display.

Therefore, the double-screen display equipment is used for displaying the video file in a split screen mode, and the video information can be continuously displayed on the second display when the video content is displayed on the first display. For example, in a dual-screen display device, when a video file is played on a large screen, a small screen displays the playing progress of the video file, and a constant display function is configured for the playing progress, so that a user can see the playing progress of the current video file in real time when watching the video file, and user experience is improved.

In some embodiments, when playing a video file, the display device provided in the embodiments of the present invention is convenient for a user to watch the video file and the video progress bar at the same time, and avoid excessive interaction, and can synchronously display the video file and the video progress bar in a split-screen manner. And according to the playing state of the video file in the first display, the progress of the video progress bar in the second display is synchronously updated, so that the time difference of the playing progress of the two screens is avoided, and further, the synchronization of the playing progress of the large screen and the small screen can be realized according to the synchronization of the playing state in different playing scenes, and the user experience is good.

FIG. 8 illustrates a block diagram of a dual screen display device according to some embodiments. In order to implement the dual-screen synchronous playing of the video 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 video files is presented; a second display 202 configured to present a second user interface in which system messages, notifications, or video information, etc. are presented; and a controller connected to the first display and the second display, the controller being configured to perform a dual screen synchronized playback method of the video file.

FIG. 9 illustrates a flow diagram of a method for dual screen synchronized playback of video files in accordance with some embodiments; fig. 10 illustrates a data flow diagram of a method for dual screen synchronized playback of a video 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 executing the dual-screen synchronous playing method for a video file shown in fig. 9 and 10, a controller is configured to execute the following steps:

and S11, responding to the operation of triggering the video file to play, and displaying the video file in the first display to play.

When a user needs to play a video file by using the display device, different video files are presented in a first user interface of the display device, and the user can click a designated video file to play the video file through a remote controller or a voice mode. The video file can be a video file provided in a certain video client, or a locally stored video file; the video client is an application configured in the display device.

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., of the tv series, the user triggers the "all are good" video file in the list by using a remote controller or a voice, and the controller obtains the video content and the video information of the video file from the server.

In order to improve the user experience, 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, after the video file is acquired from the server or locally, the video content of the video file can be displayed in the first display for playing, and the video information of the video file can be displayed in 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 pictures and enable a user to synchronously view the video progress bar when watching the video file, the video information also comprises playing progress information, the video information can be sent to the second display to be displayed, and the video content is sent to the first display to be displayed.

And S12, generating a progress bar page including a video progress bar based on the playing progress and the total duration of the video file in the playing process of the video file.

The video file is displayed in a split screen mode, and therefore the situation that the playing progress of the video content in the first display is not synchronous with the playing progress corresponding to the video progress bar in the second display easily exists due to network problems or data transmission abnormity problems. Therefore, when the video progress bar is displayed in the second display, the video progress bar in the second display can be updated in real time according to the playing progress information of the video file played in the first display, so that synchronous playing of double screens is guaranteed. The playing progress information includes the playing progress and the total duration of the video file.

In some embodiments, to implement the dual-screen synchronous playing, a video progress bar that needs to be displayed in the second display may be determined in real time according to the playing progress and the total duration of the video file during the playing of the video file, and a progress bar page including the video progress bar is generated and displayed in the second display.

The display form of the video progress bar can adopt a countdown form or a timing form, besides the video progress bar is displayed in the progress bar page, the playing state of the current video file can also be displayed, and the playing state displayed in the second display is consistent with the playing state displayed in the first display. The playing state includes pause, start playing, fast forward, fast backward, start of advertisement, end of advertisement, etc.

In some embodiments, when the video progress bar takes the countdown form, the controller, in executing the playing progress and the total duration based on the video file, generates a progress bar page including the video progress bar, and is further configured to:

step 1211, in the process of playing the video file, acquiring the total duration of the video file and the played duration corresponding to the current playing progress.

And step 1212, calculating the remaining duration based on the total duration and the broadcast duration.

And 1213, generating a progress bar page including the video progress bar based on the remaining duration, wherein the video progress bar adopts a countdown form, and the duration corresponding to the countdown form is the remaining duration.

In the process of playing the video file in the first display, the video information including the playing progress information is sent to the second display for displaying in real time from the initial playing so as to realize synchronous playing.

The playing progress information comprises the total duration of the video file and the played duration corresponding to the current playing progress. At the initial playing time, the played time length may be zero, or may be a time length corresponding to the time when the video file was watched and quitted from playing last time. For example, if the user has not viewed the video file before, the played time is zero; if the video file is viewed by the user before and is played back when the playback time reaches 20:05, the played time is 20 minutes and 5 seconds. The total duration of the video file is the duration corresponding to the complete playing of the video file.

When the countdown mode is adopted, the countdown duration is the duration of the part of the video file which is not played yet, and the display duration is gradually reduced along with the playing. Therefore, the difference between the total time length and the played time length is calculated to obtain the remaining time length. For example, the total time period T is 42 minutes, the broadcast time period T1 is 20 minutes and zero 5 seconds, and the remaining time period T2 is T-T1 is 21 minutes and zero 55 seconds.

FIG. 12 illustrates an effect diagram of a video bar in a countdown format according to some embodiments. The video progress bar in the form of a countdown is determined according to the remaining time period, and the remaining time period is displayed on the right side of the UI diagram of the video progress bar for 21 minutes and zero 55 seconds, see (a) in fig. 12. And as the play progresses, an automatic countdown is started, and 21 minutes zero 54 seconds, 21 minutes zero 53 seconds … … are displayed in order, see (b) and (c) in fig. 12.

And generating a progress bar page according to the video progress bar in the countdown mode to be displayed in the second display, so that the video progress bar in the second display dynamically adjusts time in the countdown mode along with the playing process of the video file in the first display, and the synchronous playing of the double screens is ensured.

In some embodiments, when the video progress bar is in a timed form, the controller, in executing the playing progress and the total duration based on the video file, generates a progress bar page including the video progress bar, and is further configured to:

1221, in the process of playing the video file, acquiring the total duration of the video file and the current playing time corresponding to the current playing progress;

and 1222, generating a progress bar page including a video progress bar based on the total duration and the current playing time, where the video progress bar is in a timing form, and the time corresponding to the timing form is the current playing time.

When the timing mode is adopted, the playing progress information comprises the total duration of the video file and the current playing time corresponding to the current playing progress. The current playing time refers to a time point of the total time length corresponding to the playing time length of the video file, and at the initial playing time, the current playing time can be zero minutes and zero seconds, and can also be a time corresponding to the time when the video file is watched and quitted from playing in the previous time. For example, if the video file is a completely new video file and the user has not watched the video file before, the current playing time is zero minutes and zero seconds; if the video file is viewed by the user before, or operations such as pause, fast forward or fast backward are executed, if the playing is quitted when the playing reaches 20:05 time, or operations such as pause, fast forward or fast backward are executed when the playing reaches 20:05 time, the current playing time is 20:05 when the playing is performed.

When the timing form is adopted, the timing time is the time when the video file is played, and the display time is gradually increased along with the playing. Therefore, when the progress bar page is generated, the video progress bar UI diagram is generated based on the total duration, the identification point is generated in the video progress bar UI diagram based on the current playing time, and the progress bar page is generated based on the UI diagram with the identification point and the video progress bar. And displaying the current playing time above the identification point, wherein the identification point moves to the right along the UI picture of the video progress bar along with the playing, and the current playing time above the identification point is gradually increased.

FIG. 13 illustrates an effect diagram of a video bar in a timed form according to some embodiments. Referring to fig. 13 (a), when the total time length is 42 minutes and the current play time is 20:05, a video progress bar UI diagram is generated based on the total time length 42:00, and the total time length 42:00 is displayed on the right side of the video progress bar UI diagram. And displaying an identification point at a position corresponding to the current playing time 20:05 on the UI diagram of the video progress bar, and displaying the current playing time 20:05 above the identification point. As the play progresses, see (b) and (c) in fig. 13, the identification point moves to the right position, and the current play time displayed above it is sequentially displayed 20:06, 20:07 … ….

And generating a progress bar page according to the video progress bar in the timing form to be displayed in the second display, so that the video progress bar in the second display dynamically adjusts the time in the timing form along with the playing process of the video file in the first display, and the synchronous playing of the double screens is ensured.

In some embodiments, during the playing process of the video file, the user may perform operations such as pause, fast forward, or fast backward on the video file to change the playing state of the video file. Then, when the video file in the first display performs the above operation, in order to facilitate the user to view the playing state of the video file in time, the playing state may also be displayed in the second display, and at this time, the UI diagram corresponding to the playing state is synchronously displayed in the generated progress bar page.

In some embodiments, when presenting the playing status, the controller, in executing the playing progress and the total duration based on the video file, generates a progress bar page including a video progress bar, and is further configured to:

step 1231, in the process of playing the video file, acquiring the total duration of the video file, the current playing state and the current playing time corresponding to the current playing progress.

And 1232, generating a progress bar page comprising the video progress bar and a state UI diagram based on the total duration, the current playing state and the current playing time, wherein the display form of the video progress bar comprises a countdown form and a timing form, the state UI diagram is used for representing the current playing state, and the display state of the video progress bar is consistent with the current playing state.

When the second display needs to synchronously display the playing state of the video file, if operations such as pause, start playing, fast forward or fast backward and the like are executed on the video file, the playing progress information comprises the total duration of the video file, the current playing state and the current playing time corresponding to the current playing progress. The current playing state is used for representing the operation type of the video file executed by the user, such as a pause state, a playing state, a fast forward state or a fast backward state.

And generating a video progress bar based on the total duration and the current playing time, wherein the display form of the video progress bar comprises a countdown form and a timing form, and one of the display forms can be selected to generate when the display form is generated. The generation process of the video progress bar in the countdown form and the video progress bar in the timing form can refer to the content of the foregoing embodiments, and details are not described here.

And acquiring a corresponding state UI diagram based on the current playing state, and generating a progress bar page based on the video progress bar and the state UI diagram. The state UI diagram may be displayed on one side of the video progress bar, and the playing state (the displaying state of the video progress bar) displayed by the state UI diagram is consistent with the playing state generated by the video file performing a certain operation.

FIG. 14 illustrates an effect diagram of a progress bar page including a status UI diagram according to some embodiments. Referring to fig. 14 (a), in a scenario where a video progress bar in the form of a countdown is generated, if a user performs a pause operation on a video file while 21 minutes and 55 seconds remain, a state UI diagram representing a pause state is acquired, and displayed on the left side of the video progress bar. Referring to fig. 14 (b), when the broadcast is started in the remaining 21 minutes and 42 seconds, the state UI diagram of the broadcast state is acquired and displayed by replacing the state UI diagram of the pause state with the state UI diagram of the broadcast state.

And S13, displaying the progress bar page including the video progress bar in the second display, wherein the playing progress corresponding to the video progress bar is the same as the playing progress of the video file presented in the first display.

Based on the method, after the progress bar page comprising the video progress bar is generated according to the video information of the video file, the progress bar page comprising the video progress bar is displayed in the second display.

In some embodiments, a constant display function is configured for the progress bar page, and the video progress bar can be continuously displayed in the second display, so that the user can see the corresponding playing progress in real time when watching the video file in the first display. And along with the progress of the playing process, the playing progress corresponding to the video progress bar is the same as the playing progress of the video file displayed in the first display, so that the double-screen synchronous playing is realized, and the user experience is improved.

In some embodiments, different playing states can be generated because the user can perform different types of operations on the video file during the playing process of the video file. Thus, to enable the video progress bar presented in the second display to follow the play status synchronous change when the play status change is generated, the controller is further configured to:

step 141, in the process of playing the video file, in response to a state change instruction for triggering the video file to change the playing state, generating a new progress bar page based on the playing progress corresponding to the current playing state after the playing state is changed.

And 142, displaying the new progress bar page in the second display, wherein the playing state presented in the new progress bar page is the same as the current playing state of the video file after the playing state is changed, and the playing progress presented in the new progress bar page is the same as the playing progress corresponding to the current playing state.

In the process of playing the video file in the first display, according to the actual application scene, if a user needs to execute operations such as pause, start playing, fast forward or fast backward on the video file, the playing state of the video file is changed. In order to enable the playing state of the video file to be changed, the corresponding playing progress needs to be synchronously displayed in the second display.

Therefore, when a user triggers the video file to change the playing state, a state change instruction is generated, the controller responds to the state change instruction, the video information obtained at this time comprises the playing progress corresponding to the current playing state after the playing state is changed, and a new progress bar page comprising the video progress bar is regenerated based on the current playing time corresponding to the playing progress after the state is changed and the total duration of the video file.

The time displayed on the regenerated video progress bar is the corresponding current playing time after the state is changed, the display form of the regenerated video progress bar comprises a countdown form and a timing form, and one of the display forms can be selected to be generated during generation. The contents of the foregoing embodiments can be referred to in the generation process of the video progress bar in the countdown form and the video progress bar in the timing form, and details are not described here again.

In some embodiments, when a new progress bar page is generated, a state UI diagram is also synchronously displayed, and the state UI diagram is used for representing a playing state corresponding to a certain operation performed on a video file by a user. The generation process of the state UI diagram can refer to the content of the foregoing embodiments, and will not be described herein.

And displaying the new progress bar page in the second display to update the video progress bar displayed in the second display, so that the playing state presented in the new progress bar page is the same as the current playing state after the video file playing state is changed, the playing progress presented in the new progress bar page is the same as the playing progress corresponding to the current playing state, and further the synchronous playing of the double screens is ensured.

For example, to ensure synchronization of the dual-screen play, the video progress bar in the second display stops adjusting the time when the video file in the first display is paused, and restarts adjusting the time when the video file is played again.

When the second play is started, the controller generates the progress bar page again according to the corresponding video information when the current play is started, and then the playing progress corresponding to the video progress bar in the second display is consistent with the playing progress of the video file in the first display after the pause/play starting operation is executed once.

When the video file in the first display executes fast forward or fast backward operation, based on the fast forward or fast backward time adjustment interval, generating a progress bar page again according to the video information corresponding to the time adjusted by the fast forward or fast backward operation, updating the video progress bar in the second display, wherein the time corresponding to the video progress bar is consistent with the time adjusted by the fast forward or fast backward operation executed by the video file, and further, the playing progress corresponding to the video progress bar in the second display is consistent with the playing progress of the video file in the first display.

That is to say, when an operation affecting the play progress is generated, a brand-new progress bar page is generated in real time to adjust and correct the play progress of the dual screens, so that a time difference in the play progress of the dual screens is prevented, and meanwhile, the changed play state is displayed in the second display, so that the synchronous play of the dual screens is ensured.

In some embodiments, the progress bar of the video file, and related information, may be shown only in the second display, and only the video content is shown in the first display. At the moment, the progress of the progress bar in the second display is synchronized in real time based on the operation of the user on the video content in the first display, and the double-screen synchronous playing is realized.

In some embodiments, while the progress bar of the video file and other related information are shown in the second display, the playing progress bar of the player can also be normally displayed in the first display.

In some embodiments, after the system receives the video data, the system calls a player control to play the video data, a play progress bar for displaying a play progress of the video data is generally configured in the player control, and in some embodiments, the play progress bar may be hidden when a user does not operate, and a play interface of the player is displayed after the user triggers an operation, so as to improve viewing experience of the user, and in some embodiments, the play progress bar may be displayed all the time. The playing progress bar of the player is displayed on the playing interface of the player control, and the playing interface of the player is displayed on the first display.

In some embodiments, when the video file is played on the first display, and the user pauses or otherwise manipulates the video content on the first display, a progress bar appears on the first display, and at this time, the large screen (first display) progress bar and the small screen (second display) progress bar coexist. For example, when the user pauses, the progress bar in the large screen pauses according to the traditional logic, and synchronously informs the small screen to pause the independent progress bar, so that the progress of the progress bar in the large screen and the small screen are synchronous, and the double-screen synchronous playing is realized.

In some embodiments, the progress bar of the second display is a thread in parallel with the video player.

In some embodiments, the progress bar of the second display may trigger the thread when a play interface of the player control is displayed on the first display, and may also trigger the thread when a full-screen play of the player control is displayed on the first display.

In some embodiments, the control calls the player to play the video data and display the player interface on the first display, and simultaneously starts the progress bar thread of the second display, and the second progress bar thread displays the playing progress of the progress bar based on the playing progress of the player.

In some embodiments, during the video playing, when the playing progress bar of the first display is hidden, the second progress bar of the second display still remains displayed, so that the user can intuitively know the playing progress and the watching of the video is not affected.

In some embodiments, the display interface of the second display comprises at least two areas, one area is used for displaying the progress bar, and the other area is used for displaying the prompt message.

In some embodiments, the display of the progress bar of the second display may be interrupted by a higher priority message, but the thread controlling the progress bar is still in the background, so that resuming the displayed progress bar after the message presentation is over still ensures accurate progress display.

In some embodiments, when the video file is played by using the dual screens of the display device, the second progress bar thread does not actively acquire the playing progress of the player, and the progress display of the second progress bar of the display device is controlled according to the video duration and the playing progress acquired last time and based on the current clock and the clock acquired last time. The local clock is used for controlling the progress bar of the second display, frequent communication with the player or a module for managing the player is not needed, and the running efficiency of the system is improved. If the user does not perform corresponding operations on the video content in the first display, such as pause, play, fast forward, fast backward and the like, namely during the period of no operation on the large screen, the progress bar in the second display advances the progress of the progress bar according to the local clock, and at the moment, the small screen does not depend on the large screen playing progress.

In some embodiments, since the progress bar shown in the second display is independent, the progress of the progress bar is based on the local clock, so that when the user operates the video content in the first display to pause, fast forward or fast rewind, if the progress bar in the second display still advances the progress according to its logic, a situation that the progress is inconsistent with the playing progress of the video content in the first display easily occurs, that is, the progress is asynchronous with the large screen and the small screen. At this time, the method of the present application may be adopted, based on the operation of the user on the first display, the progress bar in the second display is adjusted in real time according to the playing progress of the video content in the first display, so that the progress bar can be played synchronously with the video content.

In some embodiments, since the user's operation of the video playback is based on control of the video player, since the thread/module controlling the second progress bar will not frequently get real-time progress of the player, a problem may occur in that the playing progress of the second display and the playing progress of the player are not consistent, such as the user performing fast forward, fast reverse, pause etc. operations in the player of the first display, or the first display carries out advertisement insertion to cause that the playing of the video data playing terminal is not smooth enough, or the playing of the player is not smooth enough due to network blockage or coding and decoding blockage, in order to solve the problem, when the progress of the player has non-real-time playing conditions such as pause, start, drag, stepping and the like, the playing progress will be synchronized to the management thread/module controlling the progress bar of the second display to perform a synchronous adjustment of the progress bar of the second display.

In some embodiments, a long period of progress synchronization may be set, for example, the period is greater than or equal to 2 seconds, or even a minute-level synchronization period may be set for synchronization, and in combination with the progress bar of the second display controlled by the local clock, unnecessary loss caused by real-time synchronization may also be solved while the playing progress is accurately displayed.

In some embodiments, the pause and start operations are performed on the video file, which may be triggered automatically by the system in addition to being manually operated by the user. For example, if there is an advertisement file in a video file, in general, when the advertisement is played, the video file is in a pause state, and after the advertisement is played, the video file is played again and is in a play state.

Therefore, when the advertisement is played, the video progress bar in the second display needs to be adjusted synchronously. Specifically, in this process, the controller is further configured to:

step 151, if there is an advertisement file in the video file, acquiring the initial playing time and the ending playing time of the advertisement file corresponding to the total duration in the playing process of the video file including the advertisement file.

Step 152, in response to the pause playing instruction generated when the playing progress reaches the initial playing time, stopping playing the video file, and generating a new progress bar page based on the playing progress corresponding to the playing stop state, and displaying in the second display, where the playing stop state is presented in the new progress bar page, and the playing progress presented in the new progress bar page is the same as the playing progress corresponding to the initial playing time.

Step 153, in response to the play start instruction generated when the play progress reaches the play end time, starting to play the video file, and generating a new progress bar page based on the play progress corresponding to the play start state, and displaying in the second display, where the play start state is presented in the new progress bar page, and the play progress presented in the new progress bar page is the same as the play progress corresponding to the play end time.

When the advertisement file exists in the video file, the initial playing time and the ending playing time of the advertisement file are determined based on the time on the total time length.

Fig. 15(a) shows an effect diagram of a two-screen playing video file according to some embodiments. Referring to fig. 15(a), if the user selects the "all good" video file to play, the "all good" video content is shown in the first display, and the video information is shown in the second display. The video information includes a video name, a video set number, and a video progress bar. The video progress bar shown in fig. 15(a) takes the form of a countdown with a remaining time period of 25 minutes and 15 seconds.

In the process of continuously playing the video file, if the time corresponding to the playing progress of the video file reaches the initial playing time, the advertisement needs to be played at the moment, and the playing of the video file is paused, a pause playing instruction is generated. If the time corresponding to the playing progress of the video file reaches the playing ending time, which indicates that the advertisement is played at the moment, the video file can be played again, and then a playing starting instruction is generated.

In some embodiments, when the controller responds to the pause playing instruction, the first display starts playing the advertisement file and stops playing the video file in the background. At this time, the video file is in a stop play state.

And generating a new progress bar page based on the playing progress corresponding to the playing stop state in order to synchronize the displayed content in the second display, displaying the new progress bar page in the second display, wherein the playing stop state is presented in the new progress bar page, and the playing progress presented in the new progress bar page is the same as the playing progress corresponding to the initial playing time. The implementation process of generating the new progress bar page may refer to the content of the foregoing embodiment, and details are not described here.

Figure 15(b) illustrates an effectiveness of starting playing an advertisement file according to some embodiments. Referring to fig. 15(b), if the total time length of the video file is 42 minutes, and there is an advertisement file between 20 minutes and 15 seconds of 20 minutes, the initial playing time of the advertisement file is 20:00, and the corresponding remaining time length is 22 minutes and 0 seconds; the end play time is 20:15, corresponding to a remaining time of 21 minutes and 45 seconds. Therefore, when the initial playing time corresponding to the playing progress of the video file is 20:00, the first display starts playing the advertisement file, the background stops playing the video file, meanwhile, the video progress bar displayed in the second display is in a pause state, the time corresponding to the pause state is 20:00, and the corresponding remaining time is 22 minutes and 0 seconds.

In some embodiments, the start playing instruction is generated when the playing progress of the video file reaches the end playing time of 20: 15. When the controller responds to the play starting instruction, the advertisement file in the first display is played completely and quits displaying, and meanwhile, the first display continues to display the video file and restarts playing. At this time, the video file is in the play-enabled state, and the remaining time period corresponding to the display is 21 minutes and 45 seconds, which is not shown in the figure.

And generating a new progress bar page based on the playing progress corresponding to the starting playing state for synchronizing the display content in the second display, wherein the starting playing state is presented in the new progress bar page displayed in the second display, and the playing progress presented in the new progress bar page is the same as the playing progress corresponding to the playing ending moment. The implementation process of generating the new progress bar page may refer to the content of the foregoing embodiment, and details are not described here.

It can be seen that, when there is an advertisement file in the video file, the operations of playing the advertisement and stopping playing the advertisement are also operations that affect the playing progress and the playing state of the video file to change. Therefore, when the advertisement is played or the advertisement is played, the playing progress and the playing state of the corresponding video file are required to be synchronized to the second display, and the second display displays the video file according to the newly generated new progress bar page, so that the double-screen synchronous playing is realized.

In some embodiments, when a user performs operations such as pause/start playing/fast forwarding/fast rewinding on a video file, after the controller senses a corresponding user instruction, the playing state of the video file in the first display is changed, meanwhile, data is assembled, a progress bar page is generated and sent to the second display for displaying, and the display content of the second display is refreshed based on the current playing progress of the video file. For example, if the command is a pause command, the refreshing of the playing progress of the second display is stopped; if the command is a play start command, the play progress is refreshed based on the new progress bar page, and then the timing of playing is restarted.

In some embodiments, since the video information of the video file is a low-priority information presentation, the presentation of the video progress bar is covered if the controller sends other messages during the presentation on the second display. The priority of the message is higher than or equal to that of the video information, and the message can be related electric media asset recommendation, system notification and the like. The message is a transient message and only needs transient display, so that when the message display duration reaches a preset duration (such as 15 seconds), the display of the message is cancelled, and the video progress bar is displayed again.

FIG. 16 illustrates an effect of presenting media asset recommendation information in a second display according to some embodiments. When the video file played by the user is "all good", the two-screen display effect is as shown in fig. 15 (a). Referring to fig. 16, if the controller generates the media asset recommendation information, it is transmitted to the second display. The media asset recommendation information has a higher priority than the video information and can therefore be presented on a second display, such as "secret corner" will be played below. And after the display of the media asset recommendation information exceeds 15 seconds, canceling the display of the media asset recommendation information, displaying the video progress bar again, and recovering the state shown in fig. 15 (a).

In some embodiments, when the user exits the playing of the video file, the large screen is controlled to be released at the player, and the data notification is organized to the small screen. And after receiving the play quitting instruction, the small screen cancels the display of the progress bar and then displays the default home page of the small screen.

Thus, when the video file in the first display exits play, the controller is further configured to:

step 161, in the process of playing the video file, canceling the display of the video file in the first display and the display of the progress bar page in the second display in response to the play quitting instruction for triggering the video file to quit playing.

And step 162, acquiring a default homepage of the second display, and displaying the default homepage in the second display.

If the user wants to quit playing in the playing process of the video file, the video file is triggered to quit through a remote controller key, and a quit playing instruction is generated. At this time, the controller responds to the quit playing instruction, controls the first display not to display the video file any more, and simultaneously controls the second display not to display the progress bar page any more.

In order to restore the normal operating state of the display device, a default home page of the second display is acquired and displayed in the second display. The default home page is used to show information such as date, time, volume, number of messages, etc.

Therefore, the display device provided by the embodiment of the invention can display the video file in a split screen manner, namely, the video content of the video file is displayed in the first display, and the video information of the video file is continuously displayed in the second display, so that a user can watch the video file and the video progress bar at the same time, and excessive interaction is avoided. When the video information is displayed on the second display, the progress and the state of a video progress bar in the second display can be synchronously updated according to the playing state and the playing progress of the video file in the first display, so that the time difference generated by the playing progress of the two screens is avoided, the synchronization of the playing progress of the large screen and the small screen can be realized according to the synchronization of the playing state in different playing scenes, and the user experience is good.

When the display device provided in the foregoing embodiment executes the method for synchronously playing the video file in the dual-screen mode, the display device is applied to the display device in the dual-screen single system, and both the two displays are controlled by one overall controller, that is, the process of controlling the first display and the second display to display the content is controlled by the overall 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 double-screen double-system display equipment, 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 then the second controller controls the second display to display.

FIG. 17 illustrates a traffic sequence diagram for a method of dual screen synchronized playback of a video file according to some embodiments. Referring to fig. 17, a video file to be presented is triggered by an application (large screen application) configured in the first controller, and the large screen application acquires a specified video file from the server and generates play progress information of the video file.

In a scene of double-screen display, the first controller needs to send the playing progress information of the video file to the second controller, so that the second controller refreshes the progress of the video progress bar displayed in the second display according to the playing progress information of the video file.

In some embodiments, when the playing progress information of the video file is sent, a hiprp (dual screen information transfer channel) is configured in the first controller, and the first controller forwards the playing progress information of the video file to the second controller through the hiprp.

In some embodiments, if the user wants to view the video file, an initiating instruction is generated, and the first controller presents the video content of the video file on the first display; meanwhile, the playing progress information of the video file is forwarded to the second controller through the HIRPC. And the second controller generates a progress bar page according to the playing progress information of the video file and displays the progress bar page in the second display. The playing progress information includes a playing progress and a total duration.

In some embodiments, a fast forward instruction or a fast reverse instruction is generated if a user wants to fast forward or fast reverse a viewing video file. The first controller responds to the fast forward command or the fast backward command, and plays the video content of the video file forward or backward and displays the video content on the first display; meanwhile, the current playing progress information of the video file corresponding to the fast forward or fast backward operation is forwarded to the second controller through the HIRPC. And the second controller generates a progress bar page according to the playing progress information of the video file, and displays the progress bar page in the second display so as to refresh the video progress bar displayed in the second display.

In some embodiments, if the user wants to quit viewing the video file, a quit play instruction is generated. The first controller responds to the quit playing instruction and cancels the display of the video content in the first display; and meanwhile, forwarding an exit play instruction to the second controller through the HIRPC. The second controller acquires a default home page of the second display and displays the default home page in the second display.

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 videos is presented; a second display configured to present a second user interface in which system messages, notifications, video information, or the like are presented; a first controller connected with a first display, the first controller configured to: responding to an operation of triggering video file playing, and displaying the video file in a first display for playing; and sending the playing progress and the total duration of the video file to a second controller. And a second controller connected to the second display, the second controller being configured to perform a dual screen play progress synchronization method of the video file.

FIG. 18 illustrates another flow diagram of a method for dual screen play progress synchronization of a video file according to some embodiments. A display device according to an embodiment of the present invention may be a dual-screen dual-system display device, and when the method for synchronizing a dual-screen playing progress of a video file shown in fig. 18 is executed, the second controller is configured to execute the following steps:

s21, in the process of playing the video file, receiving the playing progress and the total duration of the video file sent by the first controller.

And S22, generating a progress bar page comprising a video progress bar based on the playing progress and the total duration of the video file.

S23, displaying the progress bar page including the video progress bar in a second display, wherein the playing progress corresponding to the video progress bar is the same as the playing progress of the video file presented in the first 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 achieved, the first controller displays video content of a video file in the first display, meanwhile, the first controller sends the generated playing progress and the total duration of the video file to the second controller, and after the second controller receives the playing progress and the total duration of the video file, a progress bar page comprising a video progress bar is generated.

And the second controller displays the progress bar page comprising the video progress bar in the second display, wherein the playing progress corresponding to the video progress bar is the same as the playing progress of the video file displayed in the first 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.

In some embodiments, when a user performs operations such as pause/start playing/fast forward/fast backward on a video file, the first controller changes the playing state of the video file in the first display after sensing a user instruction, and at the same time, performs data assembly and sends the current playing state and playing progress information corresponding to the playing progress to the second controller. And after receiving the message of the playing progress, the second controller regenerates a new progress bar page to refresh the current playing progress. For example, after receiving the instruction sent by the first controller, the second controller firstly judges the type of the instruction, and if the instruction is a pause instruction, the refreshing of the small-screen playing progress is stopped; if the command is a play start command, the play progress is refreshed based on the new progress bar page, and then the timing of playing is restarted.

In some embodiments, in the process of displaying the video progress bar on the second display, if the first controller sends another message to the second controller, the second controller determines that the priority of the message is higher than that of the video progress bar, and thus, the message overlay play progress bar is displayed on the second display. And when the message display duration reaches a preset duration (such as 15 seconds), canceling the display of the message and displaying the video progress bar again.

In some embodiments, when the user exits from playing the video file, the first controller controls the player to release, and cancels the display of the video content of the first display; meanwhile, the quit playing instruction is forwarded to the second controller, the second controller cancels the display of the progress bar after receiving the quit playing instruction, and then displays the default home page of the small screen.

Therefore, when the dual-screen display equipment is used, a user selects a video file to display through the content displayed by the first display (large screen) after starting up, and the video content of the video file is displayed on the first display; and simultaneously sending the playing progress information of the video file to the second controller. And the second controller receives the putting degree information, generates a progress bar page comprising the video progress bar and displays the progress bar page in the second display. And when the playing state of the video file in the first display changes, the video progress bar displayed in the second display is refreshed synchronously, so that the time difference between double screens is avoided, and the double-screen synchronous playing is realized. 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 double-screen synchronous playing method of the video file is executed, the video file is displayed in the first display to be played; in the video file playing process, generating a progress bar page comprising a video progress bar based on the playing progress and the total duration of the video file; and displaying the progress bar page comprising the video progress bar in the second display, wherein the playing progress corresponding to the video progress bar is the same as the playing progress of the video file displayed in the first display. Therefore, the display equipment can display the video file in a split screen mode so as to continuously display the video progress bar in the second display, a user can conveniently watch the video file and the video progress bar at the same time, and excessive interaction is avoided. In the playing process, the progress and the state of a video progress bar in a second display can be synchronously updated according to the playing state and the playing progress of a video file in a first display, the time difference generated by the playing progress of two screens is avoided, and then the synchronization of the playing progress of the large screen and the small screen can be realized according to the synchronization of the playing state in different playing scenes, so that the user experience is good.
