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..
The display device 200 may display a user interface through a browser in a partial usage scenario. For example, the display device 200 may use a browser or a portion of an application may use a browser to present a specific UI interface. The browser used may be a chrome kernel framework, and is based on a hypertext Markup Language (HTML) UI system.
The display device 200 may implement different functions according to different specific contents included in the user interface in the process of presenting the user interface using the browser. For example, a browser running on the display apparatus 200 may have both a UI function and a web browsing function. That is, when the display device 200 uses the browser to perform functions such as web browsing, a specific web browsing interface may be formed by two types of windows of the UI function and the browsing function.
The browser used by the display device 200 may include a plurality of tab pages, each of which may correspond to rendering a particular web page content. For example, as shown in fig. 5, the display device 200 may browse the a web page through a first tab page (table1) of the browser, and simultaneously browse the B web page through a second tab page (table2) after clicking a B web page link on the a web page. In the process of presenting the user interface in the browser, each tab page may be correspondingly provided with a tab option, and the user may control the display device 200 to display the corresponding web page content by selecting the tab option.
In addition, the user may also control the display device 200 to switch the display among a plurality of tab pages by switching interactive operations, such as pressing a tab key on the control apparatus 100 or selecting a switching option in the user interface, so as to repeatedly browse different web page contents. For example, as shown in fig. 6, when two tab pages, namely, a first tab page and a second tab page, are included in the user interface, the display device 200 may hide the web page content of the second tab page while displaying the first tab page. After the user inputs the switching interaction, the display device 200 may modify the display mode of each tab page, that is, display the second tab page, and hide the web page content on the first tab page.
In the process of displaying the user interface, the browser can keep a plurality of tab pages running simultaneously, for example, the browser can download resources in a plurality of web pages from the network simultaneously, so as to update the contents of the plurality of web pages. For a part of the multimedia asset playing function, a plurality of tab pages can also maintain the multimedia asset playing process of each tab page. For example, when a video element is included in a user interface presented by a browser, the display device 200 may also implement a video playing function by the browser. That is, the user may control the display apparatus 200 to access the video-based website and click any video resource link in the video-based website, so that the display apparatus 200 may display the clicked video screen content in the browser page.
Because the plurality of label pages keep synchronous operation, when any one of the plurality of label pages plays the media assets, the media asset playing process of the label page can output audio and video signals. This will cause that when one of the tab pages is displayed on the display device 200, the media asset playing process in the other tab pages will affect the audio/video output effect of the current tab page. For example, when a first tab page is opened to display a web page a and a video in the web page a is played, if a user newly opens a second tab page or switches to the second tab page to display a web page B, since the video played in the first tab page is not stopped, when the browser displays the web page B, the display device 200 still outputs audio content and video content corresponding to the video in the web page a, and if a video playing process also exists in the web page B, audio and video content output by the two tab pages may affect each other.
Moreover, because the media asset playing process in the first tab page is not suspended and resources are not released, the video in the webpage a still occupies the running memory, so that the display and media asset playing processes of the webpage B do not have sufficient running memory available, and in a severe case, the media asset playing process in the webpage B cannot be started, that is, the video playing in the webpage B fails.
In addition, when the video in the first tab page is played through the hardware playing process of the display device 200, since the display device 200 can only maintain one hardware playing process, when a new tab page is created or switched to the second tab page, the second tab page may also cause the hardware playing process to be unable to be invoked, and the problem of being unable to play the video occurs.
In order to optimize the media asset playing process under the multi-tab page, some embodiments of the present application provide a display device 200, where the display device 200 includes a display 260 and a controller 250. Wherein the display 260 is configured to display a web page screen including a plurality of tab pages. The controller 250 is configured to execute a method for playing media assets in multiple tab pages of a browser, so that when multiple tab pages exist in the browser at the same time, the media asset playing process in the original tab page is controlled, so that the media asset playing process in the original tab page does not affect the media asset playing process in other tab pages, and the specific control process can be applied to the processes of creating a tab page and switching the tab page. As shown in fig. 7, for the new tab page, the controller 250 can perform the following:
and acquiring an opening instruction which is input by a user and used for opening the new tab page. During use of the display apparatus 200 by a user, the display apparatus 200 may receive various control instructions input by the user and perform response operations corresponding to the control instructions based on the input control instructions. Therefore, when the user inputs an open instruction for opening a new tab page, the display device 200 can newly create the tab page in the browser interface in response to the open instruction. For example, when the tab page displayed by the browser is the first tab page, after the user inputs the open instruction, the second tab page may be controlled to be newly added to the browser, so as to present different web page contents through the two tab pages. For convenience of description, in the embodiment of the present application, a newly created second tab page is referred to as a new tab page, and a first tab page before the new tab page is referred to as an original tab page.
An open instruction for opening the new tab page may be input when the user accesses a certain web page address. For example, after the user inputs the website address of the web page B in the address bar of the browser and presses the enter key on the control device 100, the browser may access the website address input by the user and create a new tab page for displaying the content corresponding to the web page B.
The open instruction for opening the new tab page may also be input when the user clicks a link control on the original tab page. For example, as shown in fig. 8, a browser window may be provided with a control for creating a new tab page, and after the user selects and confirms the control for creating the new tab page, the new tab page may be triggered. Or a plurality of link controls may be provided in the web page a displayed on the first tab page, and a user may control movement of the focus cursor by using a direction key on the control device 100, or select any link control by using touch operation, at this time, the browser newly creates a tab page and accesses a link address corresponding to the link control, so as to display web page content corresponding to the link control in the newly created tab page.
When the user inputs an opening instruction by clicking the link control, the browser can also determine whether a new tab page is needed according to the specific content corresponding to the link control. For the target webpage corresponding to the link control, if the target webpage and the currently displayed webpage belong to the same type or have a parent-child relationship with the currently displayed webpage, the browser may display the content corresponding to the link control in the current tab page by default. If the target webpage does not have a strong association relation with the currently displayed webpage, the browser can display the target webpage through the new tab page. Therefore, an opening instruction for opening the new tab page can be triggered and input by a clicking action of a user on a specific link control.
Obviously, for the target web page displayed in the same tab page, the target web page can also be controlled to be displayed in a new tab page through a specific interaction. For example, as shown in fig. 9, the user may input a long-press interaction on a link control in the web page a, invoke an expansion menu, and select an "open in new tab" option in the expansion menu, triggering and inputting an open instruction for opening a new tab.
For part of the display device 200, an opening instruction for opening a new tab page may also be input through an interaction module built in or externally connected in a specific manner. For example, for the display device 200 with the built-in smart audio system, the user can "open the web page B" by inputting voice, control the browser to create a new tab page, and access the new web page address, thereby displaying the content of the web page B in the new tab page.
After acquiring the opening instruction input by the user, the display device 200 may newly create a tab page in the browser in response to the opening instruction, where the corresponding display content in the newly created tab page is the web page content specified in the user opening instruction. For example, after the user inputs the website of the web page B at the address bar of the browser and presses the enter key, the browser may create a new tab page for accessing the web page B and displaying the corresponding screen of the web page B.
The display apparatus 200 may also monitor the page status of the original tab page while the tab page is newly created. The page state comprises a background state and a display state. For tab pages in the browser, the tab pages can be divided into a display state and a background state according to whether the tab pages are displayed in the current picture or not. For example, the browser may use one tab page as a main page and other tab pages as auxiliary pages in displaying the web page. When the user views the table1 as the main page, the table1 is in a display state and occupies most of the display area in the browser. The table2 as the secondary page is in the background state and does not occupy the display area of the browser.
The original tab page is a tab page that the display apparatus 200 displays when the tab page is newly created. The page state may be retrieved from a database maintained in the browser. That is, after detecting that the user inputs an open instruction, the display device 200 may automatically start the query program to query the database of the browser for the page status of each tab page. For example, when the user controls the display apparatus 200 to newly create the second tabbed panel (table2) on the basis of displaying the first tabbed panel (table1), the first tabbed panel is regarded as the original tabbed panel. The display device 200 detects the page status of the first tab page while creating the second tab page. Monitoring the page status of the first tab page may be accomplished by querying the browser's database for real-time status data of table 1.
If the page state of the original tab page is switched from the display state to the background state, that is, after the browser is switched to display the newly-built tab page, the display device 200 can pause the media playing process in the original tab page to control the original tab page not to continue outputting the audio/video signals, and only the newly-built tab page outputs the audio/video signals, so that the interference between the audio/video signals output by the original tab page and the contents in the newly-built tab page is relieved.
For example, when the web page a of the first tab page is a video playing page, after it is monitored that the first tab page is shifted from the display state to the background state, the display device 200 may pause the video playing process on the first tab page, so that the first tab page is maintained in the still state and no audio/video signal is output.
After the video playing process in the original tab page is suspended, in order to reduce the occupation of the running memory resources by the original tab page, the display device 200 may also release the associated memory resources occupied by the media resource playing process, so that the original tab page is in a frozen state. The memory release operation performed on the original tag page is only performed for the media asset playing process, that is, after the media asset playing process is released, the display device 200 does not acquire the media asset related data and the webpage update related data from the network according to the media asset playing process any more, and does not perform playing operations such as decoding on the played media asset any more. The original tab page remains running in the background so that the user can switch back to the original tab page when needed.
After the memory resources corresponding to the media asset playing process are released, the browser of the display device 200 can use the released memory in the display process of the newly-built tab page through a memory recovery mechanism, so that the running memory capacity of the display device 200 in the process of newly-built tab pages is increased, the display speed of the newly-built tab pages is increased, and the interference of the original tab pages on the newly-built tab pages is reduced.
As can be seen, in the above embodiment, when the browser is controlled to newly create a tab page, the display device 200 may automatically pause the media asset playing process on the original tab page after the original tab page is turned into the background state by detecting the page state of the original tab page, and release the memory resource related to the media asset playing process, so as to reduce interference of the media asset playing process in the original tab page on the newly created tab page, and improve user experience.
In the above embodiment, the display device 200 may control the playing process of the media assets in the original tab page to reduce the interference of the media assets with the new tab page. And for a part of the web pages, the media asset playing process may not be included or is not in a playing state in the process of displaying the original label page.
Therefore, as shown in fig. 10, in some embodiments, the display device 200 may further detect an operation state of a media asset playing process in an original tab page, and adopt different control modes according to different operation states. Namely, in the step of pausing the media asset playing process in the original label page, the running state of the media asset playing process in the original label page is detected. The running state comprises a playing state and a stop state, and the running state can be obtained from a database maintained by the browser. For example, after receiving an open instruction input by a user, the display device 200 may read an operation state entry of a first tab page in the browser, and when the state value corresponding to the operation state entry is read to be "1", it represents that a media asset playing process in the first tab page is in a playing state; and when the state value corresponding to the running state table entry is read to be 0, the media asset playing process in the first label page is in the stop state.
By detecting the running state of the media asset playing process, if the corresponding running state of the media asset playing process in the original tag page is the playing state, that is, the media asset playing process in the original tag page is playing the multimedia resource, and outputting the audio and video signal. Accordingly, the display apparatus 200 can pause the media asset playing process in the original tab page by setting the running state to the stop state. Similarly, if the corresponding running state of the media asset playing process in the original tab page is the off-air state, that is, the media asset playing process is not running in the current original tab page, the original tab page does not generate an audio/video signal capable of affecting the newly-created tab page, so that the display device 200 can control the browser to directly display the newly-created tab page.
For example, the display device 200 may determine that a media asset playing process outputting audio/video signals exists in the current first tab page when the state value is determined to be "1" by reading the state value corresponding to the running state table entry of the first tab page, and thus, in order to reduce interference of the media asset playing process of the first tab page on the newly-created second tab page, the display device 200 may set the corresponding state value from "1" to "0" to thereby pause the media asset playing process. When the state value is determined to be "0", the display device 200 directly creates a second tab page in the browser without setting a media asset playing process.
In some embodiments, the display device 200 may further extract a current playing progress of the media asset playing progress after the media asset playing progress in the original tab page is paused, and record the current playing progress, so as to enable the media asset playing progress according to the current playing progress when the user switches back to the original tab page. Wherein, the recorded playing progress can be the time point to which the current media asset is played, such as 0:13: 14; or the play proportion of the current media assets, such as 45%. For each tab page included in the browser, the display device 200 may correspondingly establish a play progress entry, such as "play back progress", and a specific state value of the entry may represent a play progress of the media asset in the corresponding tab page. For example, by setting the play schedule item to "Playback progress 01314", it means that the current play time point is 0:13: 14. Or, by setting the status value "Playback progress" of the table entry to 45 ", it means that the current Playback progress ratio is 45%.
The display device 200 may store the extracted playing schedule in a permanent storage such as a hard disk, so that when the associated running memory of the media asset playing schedule is released, the playing schedule may be reserved, and when the user subsequently switches back to the original tab page, the display device 200 may acquire the playing schedule from the storage such as the hard disk. It should be noted that the storage time of the playing schedule in the hard disk can also be determined according to the use state of the user. For example, the recorded play progress data may be deleted from the hard disk when the user selects to close the first tab page.
In some embodiments, the display device 200 may also monitor the running memory in real time during running, and adjust a control mode of the media asset playing progress according to different running memory residuals. That is, as shown in fig. 11, the display device 200 may detect the remaining amount of the currently running memory in the step of releasing the associated memory resource occupied by the media asset playing process. The current running memory surplus can be obtained through a memory monitoring module in the browser.
For example, the process architecture in a Browser can be divided into three classes, namely a browse process, a Render process, and other processes. The Browser process comprises key modules such as memory monitoring and webpage resource downloading; the Render process is responsible for rendering the webpage and comprises a resource request module, and a plurality of Render processes can be arranged according to the opened tags (tab); other processes may include Graphics Processing Unit (GPU), plug-in, etc. functional processes to implement corresponding Graphics Processing or plug-in functionality. Data Communication between processes can be realized by Inter-Process Communication (IPC). After the user inputs an open instruction, the controller 250 of the display device 200 may detect the remaining amount of the currently operating memory in real time through a memory monitoring module in the Browser process, and compare the detected remaining amount of the operating memory with a preset memory.
If the remaining amount of the operating memory is less than or equal to the preset memory threshold, that is, the remaining amount of the operating memory of the current display device 200 is insufficient, in order to reduce the occupation of the operating memory resources by the multiple tab pages, the display device 200 may first release the associated memory resources occupied by the media asset playing process, and after releasing the associated memory resources, control the browser to display the newly created tab pages. Therefore, the newly-built label page can directly utilize the memory resource associated with the media asset playing process, and further consumption of the running memory is reduced.
If the remaining amount of the operating memory is greater than the preset memory threshold, that is, the remaining amount of the operating memory of the current display device 200 is sufficient, so that in order to increase the display speed of the newly-created tab page, the display device 20 may control the browser to display the newly-created tab page, and release the associated memory resource occupied by the media asset playing process.
Therefore, in this embodiment, by adjusting the sequence of releasing the memory and the new tab page in different operating memory remaining amounts, the display device 200 can complete operations of creating the tab page and releasing the memory through reasonable operating memory consumption, maintain the good operating state of the display device 200, and improve user experience.
According to the embodiment, a user can newly build a plurality of tab pages in the browser by inputting the opening instruction for multiple times, and the tab pages can present different webpage contents according to the specified webpage addresses in the newly-built process. The display apparatus 200 may also switch the display between a plurality of tab pages as the user uses. Since the switching process of the tab pages also causes a plurality of page states to change, when the tab pages are switched, mutual interference exists between different tab pages.
As shown in fig. 12, in order to alleviate mutual interference between multiple tab pages when switching tab pages, in some embodiments, the display device 200 may further obtain a switching instruction input by a user for switching display among multiple tab pages when multiple tab pages are included in the browser. Like the opening command, the switching command input by the user may be input by the control device 100, the input website, the touch screen, the smart phone system, and the like.
For example, when three tab pages in the browser respectively display a web page a, a web page B, and a web page C, that is, a first tab page displays the web page a, a second tab page displays the web page B, and a third tab page displays the web page C. The user can control the focus cursor movement by the direction key and the confirmation key on the control device 100 so as to select the tab option of each tab page and control the browser to display the corresponding web page. If the browser displays the webpage C of the third tab page, the browser may be controlled to switch to the second tab page by clicking a tab option of the second tab page at the top of the browser, and at this time, the display device 200 obtains a switching instruction for switching to the displayed webpage B, which is input by the user.
After the user inputs the switching instruction, the display device 200 may set the page state of the currently displayed focus tab in response to the switching instruction, that is, may set the page state of the focus tab from the display state to the background state. And the focus tab page is a tab page currently displayed when the user inputs the switching instruction. For example, when the browser is displaying the webpage C of the third tab page, the current focus tab page is the third tab page. The current page states of the tab pages in the browser are respectively a first tab page and a second tab page which are background states, and the third tab page is a display state. When the user clicks the tab option of the second tab page, the display device 200 may set the page state of the third tab page to be a background state, so that the third tab page maintains background operation. Meanwhile, the page state of the second tab page is set to a display state, so that the browser can display the web page B on the second tab page.
After setting the page state of the focus tab to the background state, the display device 200 may further detect a media asset playing process in the focus tab. The detection content of the media asset playing process comprises whether the media asset playing process is contained or not and the specific state parameters in the media asset playing process. The display device 200 may obtain whether the current page includes a media asset playing process by reading a real-time database in the browser. The display device 200 may also determine whether a media asset playing process is involved by analyzing the content in the tab page. For example, for a video playing interface, the display device 200 may obtain page screenshots at a plurality of different time points, identify the page screenshots, and determine whether the web page contains an area with changed image content. If the displayed webpage has an area with changed image content, the current tab page can be determined to contain a media asset playing process.
By detecting the point-of-examination tab, it is determined that the focus tab contains a media asset playing process, and the display device 200 may also pause the media asset playing process in the focus tab. For example, in the process of switching the tab page displayed by the browser from the third tab page to the second tab page, if the display device 200 detects that the third tab page contains a media asset playing process, the media asset playing process in the tab page may be paused to relieve the influence of the media asset playing process of the third tab page on the content presentation of the second tab page.
The display device 200 may also detect the switched tab media asset playing process, and control the switched tab media asset playing process according to the detection result. That is, as shown in fig. 13, in some embodiments, the display apparatus 200 may set the page state of the target tab page to the display state after setting the page state of the focus tab page to the background state. Wherein the target tab page is a tab page specified to be switched in the switching instruction. For example, in the process of switching the display tab page of the browser from the third tab page to the second tab page, the third tab page is the focus tab page, and the second tab page is the tab page specified by the user to be switched, i.e. the target tab page.
After setting the target tab page to be in the display state, the display device 200 may further detect a media asset playing process in the target tab page. If the target label page contains the media asset playing progress, the media asset playing progress can be extracted, and the media asset playing progress in the target label page is started according to the extracted media asset playing progress so as to continue playing the media asset content in the target label page. For example, after detecting that the second tab page also contains a media asset playing process, the display device 200 may send an inquiry request to a memory such as a hard disk according to the name "table 2" of the second tab page, so as to inquire that the playing progress is 0:13:14, that is, the media asset in the second tab page is played to the time point position of 0:13:14 when the media asset in the second tab page was last suspended. And, after the page status of the second tab page is set to the display status, i.e., the browser switches to display the second tab page, the display apparatus 200 continues to play again from the time point of 0:13: 14.
As can be seen, in the above embodiment, the display device 200 may automatically pause the media asset playing process in the focus tab when switching between multiple tab pages, and continue playing the media asset according to the previously stored playing progress of the media asset playing process in the target tab page. Through the automatic start-stop control of the video playing process in the plurality of label pages, the mutual interference among the plurality of label pages is reduced, and the user experience is improved.
Similar to the process of newly creating the tab page, when the tab page is switched, the display device 200 may also release the associated memory resource occupied by the media asset playing process after the media asset playing process is paused. But the operating frequency of the user for switching among the plurality of tab pages is higher than that of the newly created tab page. I.e. the user may switch between different tab pages several times in a short time.
Therefore, as shown in fig. 14, in some embodiments, the display device 200 needs to have a certain delay for releasing the associated memory resource corresponding to the media asset playing process, that is, after acquiring the switching instruction for switching and displaying among the plurality of tab pages, which is input by the user, the display device 200 may detect the switching instruction input by the user within a preset switching period. The preset switching period may be set according to hardware performance of different display devices 200, for example, the preset switching period is 30 s.
If the user does not input the switching instruction again in the switching period, the user is determined not to frequently switch a plurality of label pages in a short time, so that the associated memory resources occupied by the media asset playing process in the focus label page can be released. That is, the display device 200 may delay the memory resource occupied by the media asset playing process for a certain time and then release the memory resource, so that the user inputs the switching instruction again in the switching period, may directly continue to operate the media asset playing process, and maintain the media asset playing process in the focus tab in the operating memory until the user does not input the switching instruction again in the preset switching period.
As can be seen, the display device 200 may detect whether the switching instruction input by the user is received again within a certain time after the switching instruction is obtained, so that when the user frequently switches the tab page, the corresponding media asset playing process can be always maintained in the pause state, and does not enter the freeze state. Therefore, the above embodiment can avoid the display device 200 storing and retrieving the playing progress for multiple times, and improve the response speed of the media asset playing progress.
In some embodiments, the display device 200 may also count the input frequency of the switching instructions for frequent switching processes by the user. If the input frequency is greater than or equal to the preset frequency threshold, the maintaining time of the media asset playing process in the focus label page in the running memory can be prolonged so as to adapt to the frequent switching operation of the user. If the input frequency is smaller than the preset frequency threshold, the maintaining time of the media asset playing process in the focus label page in the running memory is shortened, so that the memory resources occupied by the media asset playing process in the inactive label page can be released in time, and the utilization rate of the running memory is improved.
In some embodiments, the display device 200 may further detect a current running memory remaining amount, and set a maintaining time of the media asset playing process in the memory according to the running memory remaining amount. If the remaining amount of the running memory is less than or equal to the first threshold, the maintaining time of the media asset playing process in the focus label page in the running memory is shortened, the available running memory is recycled in time, and the processing efficiency of the subsequent process is improved. If the remaining amount of the running memory is greater than the second threshold, the maintaining time of the media asset playing process in the focus tab in the running memory is prolonged, so that the storage and extraction times of the subsequent playing progress are reduced on the premise of not influencing the processing capacity of the display device 200. Obviously, the second threshold needs to be greater than the first threshold.
Based on the display device 200, in some embodiments of the present application, a method for playing media assets in a browser multi-tab page is further provided, and is applied to the display device 200; the method for playing the media assets of the browser multi-tab page comprises the following steps:
acquiring an opening instruction which is input by a user and used for opening the new tab page;
monitoring the page state of an original label page in response to the opening instruction, wherein the page state comprises a background state and a display state;
and after the page state of the original label page is switched to the background state from the display state, pausing the media asset playing process in the original label page and releasing the associated memory resources occupied by the media asset playing process.
According to the technical scheme, the method for playing the media assets of the browser multi-tab page provided by the embodiment can monitor the page state of the original tab page after the user controls the new tab page. When the page state of the original label page is changed into the background state from the display state, the media asset playing process in the original label page can be paused, and the associated memory resources occupied by the media asset playing process are released. According to the method, when a plurality of label pages exist in the browser at the same time, the mutual influence of media assets played in the plurality of label pages is relieved by pausing the media asset playing process, and meanwhile, the occupation of the media asset playing process in the original label page on the running memory space is reduced by releasing the associated memory resources corresponding to the playing process, so that the display and operation fluency of the browser is improved, and the user experience is enhanced.
The embodiments provided in the present application are only a few examples of the general concept of the present application, and do not limit the scope of the present application. Any other embodiments extended according to the scheme of the present application without inventive efforts will be within the scope of protection of the present application for a person skilled in the art.
