The display device 200 may display a user interface through a browser in a partial use scenario. For example, the display device 200 may use a browser or a portion of the application may use a browser to present a particular UI interface. Wherein the browser used may be a chrome kernel framework, while a UI system based on hypertext markup language (Hyper Text Markup Language, HTML).
The display device 200 may implement different functions according to specific contents included in a user interface in presenting the user interface using a browser. For example, a browser operated by the display device 200 may have both a UI function and a web browsing function. That is, when the display device 200 performs functions such as web browsing using the above-described browser, a specific web browsing interface may be formed by two types of windows, i.e., a UI function and a browsing function.
The browser used by the display device 200 may include a plurality of tabbed pages, each of which may correspond to rendering a particular web page content. For example, as shown in fig. 5, the display apparatus 200 may browse the a web page through a first tab page (table 1) of the browser, and at the same time browse the B web page through a second tab page (table 2) after clicking the B web page link on the a web page. During the process of presenting the user interface by the browser, each tab page may be correspondingly provided with a tab option, and the user may control the display device 200 to display corresponding web page content by selecting the tab option.
In addition, the user may also switch the display device 200 between a plurality of tab pages through a switching interaction operation, such as pressing a tab key on the control device 100 or selecting a switching option in a user interface, so as to repeatedly browse different web page contents. For example, as shown in fig. 6, when two tab pages of a first tab page and a second tab page are included in the user interface, the display apparatus 200 may hide the web page contents of the second tab page while the first tab page is displayed. After the user inputs the switching interaction, the display device 200 may modify the display manner of each tab page, that is, display the second tab page, while hiding 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 a network simultaneously, so that the update of the contents of the web pages is realized. For part of the media information playing function, the plurality of tag pages can also maintain the media information playing process of each tag page. For example, when a video element is included in a user interface presented through a browser, the display device 200 may also implement a video play function through the browser. That is, the user can control the display device 200 to access the video-type website and click on any video resource link in the video-type website so that the display device 200 can display the clicked video picture content in the browser page.
Because the plurality of tag pages keep synchronous operation, when any one of the plurality of tag pages plays the media asset, the media asset playing process of the tag pages can output audio and video signals. This results in that when one of the tab pages is displayed by the display device 200, the audio/video output effect of the current tab page is affected by the media playback process in the other tab page. For example, when the first tab page is opened to display the web page a and the video in the web page a is played, if the user newly opens a second tab page or switches to the second tab page to display the 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 the audio content and the video content corresponding to the video in the web page a, and if the video playing process also exists in the web page B, the audio and video contents output by the two tab pages affect each other.
In addition, since the media playing process in the first tab page is not paused and resources are released, the video in the web page a still occupies the running memory, so that the display of the web page B and the media playing process have insufficient running memory availability, and in serious cases, the media playing process in the web page B cannot be started, that is, the video playing in the web page 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 the second tab page is newly built or switched to, the second tab page can not call the hardware playing process, and the problem that the video cannot be played occurs.
In order to optimize the media playback process under the multi-tab page, some embodiments of the present application provide a display device 200, the display device 200 including 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 of multiple tab pages of the 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 in the processes of creating new tab pages and switching tab pages. As shown in fig. 7, for the new tab page, the controller 250 may perform the following:
And acquiring an opening instruction which is input by a user and is used for opening the newly built tab page. In the course of using the display apparatus 200 by the 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. Accordingly, when the user inputs an opening instruction for opening the newly created tab page, the display apparatus 200 may newly create the tab page in the browser interface in response to the opening instruction. For example, when the tab page displayed by the browser is the first tab page, after the user inputs the opening instruction, the user may control to add a second tab page in 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, the newly created second tab page is referred to as a new tab page, and the first tab page before the new tab page is referred to as an original tab page.
An open instruction for opening a newly created tab page may be input when a user accesses a certain web page address. For example, the user may input the web address of the web page B in the address bar of the browser, press the confirm key on the control device 100, and then the browser may access the web address input by the user, and create a tab page for displaying the content corresponding to the web page B.
The open instruction for opening the new tab page may also be entered when the user clicks a link control on the original tab page. For example, as shown in fig. 8, a new tab control may be provided on the browser window, and when the user selects and confirms the new tab control, the new tab may be triggered. Or a plurality of link controls can be set in the web page a displayed on the first tab, the user can control the focus cursor to move through directional control on the control device 100, or select any link control through touch operation, at this time, the browser builds a tab, and accesses the link address corresponding to the link control, so that the web page content corresponding to the link control is displayed in the newly built tab.
When the user inputs an opening instruction by clicking the link control, the browser can also determine whether to newly build the tab page according to specific content corresponding to the link control. For the target webpage corresponding to the link control, if the target webpage and the current display webpage belong to the same type or have a parent-child relationship with the current display webpage, the browser can default to display the content corresponding to the link control in the current tab page. If the target webpage has no strong association relation with the currently displayed webpage, the browser can display the target webpage through the newly-built tab page. Thus, an open instruction to open a newly created tab page may trigger an input by a user's click action on a particular link control.
Obviously, for the target web page displayed in the same tab page, the target web page can be controlled to be displayed in a new tab page through a specific interaction action. For example, as shown in FIG. 9, the user may enter a long press interaction on a link control in web page A, invoke an expanded menu, and select the "open in new tab" option in the expanded menu, triggering entry of an open instruction for opening the newly created tab.
For the partial display device 200, an opening instruction for opening the newly built tab page may also be input through an interaction module built in or externally connected to a specific manner. For example, with the display device 200 of the built-in smart phone system, the user can "open web page B" by inputting a voice, control the browser to newly create a tab page, and access a new web page address, thereby displaying the contents of web page B in the newly created tab page.
After acquiring the opening instruction input by the user, the display device 200 may newly build a tab page in the browser in response to the opening instruction, where the corresponding display content in the newly built tab page is the web page content specified in the opening instruction of the user. For example, after the user inputs the web address of the web page B in the address bar position of the browser and presses the confirm key, the browser may create a tab page for accessing the web page B and displaying the screen corresponding to the web page B.
The display apparatus 200 may also monitor the page status of the original tab page while newly creating the tab page. The page state comprises a background state and a display state. For a tab page in a browser, it can be divided into a display state and a background state according to whether it is displayed in a current screen. For example, the browser may have one tab page as a main page and other tab pages as sub pages during the display of the web page. When a user views table1 as a main page, table1 is in a display state and occupies most of the display area in the browser. Table2, which is a sub page, is in a background state and does not occupy the display area of the browser.
The original tab page refers to a tab page that the display device 200 displays when creating a tab page. The page status may be obtained by extraction from a database maintained in the browser. That is, the display device 200 may automatically start a query program after detecting that the user inputs an open instruction, and 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 tab page (table 2) on the basis of displaying the first tab page (table 1), the first tab page serves as the original tab page. The display apparatus 200 detects the page status of the first tab page while newly creating the second tab page. By inquiring real-time state data of the table1 from a database of the browser, the monitoring of the page state of the first tab page can be realized.
If it is monitored that the page state of the original tab page is changed from the display state to the background state, that is, after the browser is switched to display the new tab page, the display device 200 can pause the media playing process in the original tab page, so as to control the original tab page not to continue outputting audio and video signals, and only the new tab page outputs audio and video signals, thereby alleviating interference between the audio and video signals output by the original tab page and the content in the new tab page.
For example, when the web page a of the first tab page is a video playing page, after the first tab page is monitored to be 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 kept in the still state, and no audio/video signal is output.
After suspending the video playing process in the original tag page, in order to reduce the occupation of the running memory resources by the original tag page, the display device 200 may also release the associated memory resources occupied by the media playing process, so that the original tag page is in a frozen state. The memory releasing operation performed on the original tag page is only aimed at the media playing process, that is, after the media playing process is released, the display device 200 does not acquire media related data and web page update related data from the network according to the media playing process any more, and does not perform playing operations such as decoding on playing media any more. The original tab page remains in background operation so that the user switches back to the original tab page when needed.
After the memory resources corresponding to the media resource playing process are released, the browser of the display device 200 can use the released memory in the display process of the new tab through a memory recycling mechanism, so that the running memory capacity of the display device 200 in the process of the new tab is increased, the display speed of the new tab is increased, and the interference of the original tab to the new tab is reduced.
It can be seen that, in the above embodiment, when the display device 200 controls the new tab page of the browser, by detecting the page state of the original tab page, the original tab page automatically pauses the media playing process on the original tab page after being shifted to the background state, and releases the memory resources related to the media playing process, so as to reduce the interference of the media playing process in the original tab page to the new tab page, and improve the user experience.
In the above embodiment, the display device 200 may control the media playback process in the original tab page to reduce the interference to the new page. For some web pages, the media playing process may not be included or in the process of displaying the original tab page, the media playing process is not in a playing state.
Thus, as shown in fig. 10, in some embodiments, the display device 200 may further detect the running state of the media playback process in the original tag page, and use different control manners according to different running states. And detecting the running state of the media playing process in the original tag page in the step of suspending the media playing process in the original tag page. The running state comprises a playing state and a stopping state, and the running state can be obtained from a database maintained by the browser. For example, after receiving an opening instruction input by a user, the display device 200 may read an operation state table entry of a first tab page in the browser, and when the read operation state table entry corresponds to a state value of "1", it represents that a media playing process in the first tab page is in a playing state; when the corresponding state value of the operation state table item is read to be 0, the media resource playing process in the first label page is in the off-air state.
And detecting the running state of the media asset playing process, and if the corresponding running state of the media asset playing process in the original tag page is the playing state, namely the media asset playing process in the original tag page is playing the multimedia resource, and outputting the audio and video signals. Accordingly, the display apparatus 200 can pause the media playback process in the original tab page by setting the running state to the off-air state. Similarly, if the corresponding running state of the media playing process in the original tab page is the off-air state, that is, the media playing process is not running in the current original tab page, the original tab page will not generate audio and video signals that can affect the new tab page, so the display device 200 can control the browser to directly display the new tab page.
For example, the display apparatus 200 may determine that there is a media playback progress in the first tab currently outputting an audio/video signal when it is determined that the status value is "1" by reading the status value corresponding to the running status entry of the first tab, so in order to reduce interference of the media playback progress of the first tab with the newly created second tab, the display apparatus 200 may set the corresponding status value from "1" to "0" to thereby suspend the media playback progress. When the status value is determined to be "0", the display device 200 does not need to set the media playing process, and only needs to directly newly build the second tab page in the browser.
In some embodiments, the display device 200 may further extract a current playing progress of the media playback progress after suspending the media playback progress in the original tab page, and record the current playing progress, so as to enable the media playback progress according to the current playing progress when the user switches back to the original tab page. The recorded playing progress can be the time point to which the current media asset is played, such as 0:13:14; or the playing proportion of the current media asset, such as 45%. For each tab page included in the browser, the display device 200 may correspondingly establish a play schedule item, such as "Playback progress", and the specific status value of the schedule item may represent the media play schedule in the corresponding tab page. For example, by setting the play schedule item to "Playback progress = 01314", it is indicated that the current play time point is 0:13:14. Or by setting the status value "Playback progress =45" of the table entry, the current playing progress rate is indicated to be 45%.
The display device 200 may store the extracted playing progress in a persistent memory such as a hard disk, so that when the associated running memory of the media resource playing process is released, the playing progress may be reserved, and when the user switches back to the original tab page, the display device 200 may obtain the playing progress from the memory such as the hard disk. It should be noted that, the storage time of the playing progress in the hard disk may 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 operation, and adjust the control manner of the media playback progress according to different running memory residuals. That is, as shown in fig. 11, the display device 200 may detect the current running memory residual in the step of releasing the associated memory resources occupied by the media asset playing process. The current running memory residual quantity can be obtained through a memory monitoring module in the browser.
For example, the process architecture in a Browser can be divided into three categories, namely a browse (Browser) process, a Render (Render) process, and others. The Browser process comprises key modules such as memory monitoring, webpage resource downloading and the like; the Render process is responsible for rendering the webpage and comprises a resource request module, and the Render process can be provided with a plurality of tags according to the opened tag (tab); other processes may include graphics processor (Graphics Processing Unit, GPU), plug-in, etc. functional processes to implement corresponding graphics processing or plug-in functions. Data communication between processes may be achieved through Inter-process communication (Inter-Process Communication, IPC). After the user inputs the opening command, the controller 250 of the display device 200 may detect the remaining amount of the current running memory in real time through the memory monitoring module in the Browser process, and compare the detected running memory remaining amount with the preset memory.
If the running memory remaining amount is less than or equal to the preset memory threshold, that is, the running memory remaining amount of the current display device 200 is insufficient, in order to reduce the occupation of the running memory resources by the plurality of tab pages, the display device 200 may first release the associated memory resources occupied by the media resource playing process, and after releasing the associated memory resources, control the browser to display the newly-built tab page. Therefore, the newly built tab page can directly utilize the memory resources associated with the media resource playing process, and further consumption of the running memory is reduced.
If the running memory remaining amount is greater than the preset memory threshold, that is, the running memory remaining amount of the current display device 200 is sufficient, so in order to increase the display speed of the new tab page, the display device 20 may control the browser to display the new tab page, and simultaneously release the associated memory resource occupied by the media playback process.
Therefore, in this embodiment, by adjusting the order of releasing the memory and newly-built tag pages under different running memory residuals, the display device 200 can complete the operations of newly-built tag pages and releasing the memory through reasonable running memory consumption, so as to maintain the display device 200 in a good running state, and improve user experience.
According to the embodiment, the user can newly establish a plurality of tab pages in the browser by inputting the opening instruction for a plurality of times, and the tab pages can present different webpage contents according to the webpage address designated in the new establishment process. The display device 200 may also switch display among a plurality of tab pages as the user uses. Since the switching process of the tab pages also causes a change in the states of a plurality of pages, there is a mutual interference between different tab pages when the tab pages are switched.
As shown in fig. 12, in order to alleviate mutual interference between a plurality of 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 between the plurality of tab pages when the plurality of tab pages are included in the browser. The switching command input by the user may be input by the control device 100, inputting a web address, a touch screen, an intelligent voice system, and the like, as in the opening command.
For example, when three tab pages in the browser display web page a, web page B, and web page C, respectively, i.e., a first tab page displays web page a, a second tab page displays web page B, and a third tab page displays web page C. The user can control the focus cursor movement through 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. When the browser is displaying the webpage C of the third tab page, the browser can be controlled to switch to the second tab page by clicking the 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 display the webpage B, which is input by the user.
After the user inputs the switching instruction, the display apparatus 200 may set the page state of the currently displayed focus tab page in response to the switching instruction, that is, may set the page state of the focus tab page from the display state to the background state. The focus tab page is a tab page currently displayed when the user inputs the switching instruction. For example, when the browser is displaying web page C of the third tab page, then the currently focused 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 in a background state, and a third tab page is in 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 a background state, so that the third tab page maintains the background operation. And simultaneously, setting the page state of the second tab page to be a display state, so that the browser can display the webpage B on the second tab page.
After setting the page state of the focus tab page to the background state, the display device 200 may also detect the media playback progress in the focus tab page. The detection content of the media asset playing process comprises whether the media asset playing process is contained or not and specific state parameters in the media asset playing process. The display device 200 may obtain whether the current page contains the media playing process by reading the real-time database in the browser. The display device 200 may also determine whether the media asset playing process is contained therein by analyzing the contents in the tab page. For example, for a video playback interface, the display device 200 may obtain page shots at a plurality of different points in time and identify the page shots to determine whether the web page contains areas of varying image content. If the displayed webpage has an area with changed image content, the current tag page can be determined to contain the media asset playing process.
By detecting the check tab page, determining that the focus tab page contains a media playback process, the display device 200 may also pause the media playback process in the focus tab page. 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 playback process, the media playback process in the tab page may be paused, so as to alleviate the content presentation of the second tab page from being affected by the media playback process of the third tab page.
The display device 200 may further detect the media asset playing process of the switched tab page, and control the media asset playing process of the switched tab page according to the detection result. That is, as shown in fig. 13, in some embodiments, the display device 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. The target tab page is a tab page designated for switching 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 that the user designates to switch, i.e., the target tab page.
After setting the target tab page to the display state, the display device 200 may also detect a media playback progress in the target tab page. If the target label page contains the media asset playing process, the media asset playing process can be extracted, and the media asset playing process in the target label page is started according to the extracted media asset playing process so as to continuously play 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 a query request to a memory such as a hard disk according to the name "table2" of the second tab page, so as to query that the playing process 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 is paused last time. And, after the page status of the second tab page is set to the display status, that is, the browser switches to display the second tab page, the display device 200 continues to play from the time point of 0:13:14.
It can be seen that, in the above embodiment, the display device 200 may automatically pause the media playback process in the focus tab page when switching between the tab pages, and continue the media playback according to the playback progress of the media playback process in the previously stored target tab page. Through the automatic start-stop control of the video playing process in the plurality of tag pages, the mutual interference among the plurality of tag pages is reduced, and the user experience is improved.
Similar to the process of creating a tab page, when switching tab pages, the display device 200 may also release the associated memory resources occupied by the media playback process after suspending the media playback process. But since the user switches between tab pages at a higher frequency than the newly created tab page. I.e. the user may switch between different tab pages multiple 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, the display device 200 may detect the switching instruction input by the user in the preset switching period after acquiring the switching instruction input by the user for switching the display on the plurality of tab pages. The preset switching period may be set according to the hardware performance of different display devices 200, for example, the preset switching period is 30s.
If the user does not input the switching instruction again in the switching period, the user is determined to not switch a plurality of tag pages frequently in a short time, so that the associated memory resources occupied by the media playing process in the focus tag page can be released. That is, the display device 200 may delay the memory resources occupied by the media playing process for a certain time to release, so that the user inputs the switching instruction again in the switching period, and may directly continue to operate the media playing process, and maintain the media playing process in the focus tag page in the operation memory until the user does not input the switching instruction again in the preset switching period.
It can be seen that, the display device 200 may detect whether the switching instruction input by the user is received again within a certain period of time after the switching instruction is acquired, so that when the user frequently switches the tab page, the corresponding media playing process can be always kept only in a pause state and does not enter a frozen state. Therefore, the above embodiment can avoid the display device 200 to store and extract the playing progress multiple times, and improve the response speed of the media asset playing progress.
In some embodiments, the display device 200 may also count the frequency of input of the switch instruction for frequent switching procedures by the user. If the input frequency is greater than or equal to the preset frequency threshold, the maintenance time of the media asset playing process in the running memory in the focus tag page 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 maintenance time of the media resource playing process in the focus tag page in the running memory is shortened, so that the memory resources occupied by the media resource playing process in the inactive tag page are released in time, and the utilization rate of the running memory is improved.
In some embodiments, the display device 200 may also detect the current running memory residual and set the maintenance time of the media playback process in the memory according to the running memory residual. If the running memory surplus is smaller than or equal to the first threshold value, the maintenance time of the media resource playing process in the running memory in the focus tag page is shortened, the available running memory is recovered in time, and the processing efficiency of the follow-up process is improved. If the running memory remaining amount is greater than the second threshold value, the maintenance time of the media asset playing process in the focus tag page 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 affecting 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 on multiple tabs of a browser is further provided, which is applied to the display device 200; the method for playing the multi-label page media assets of the browser comprises the following steps:
acquiring an opening instruction input by a user for opening a newly built tab page;
responding to the opening instruction, monitoring the page state of an original tag page, wherein the page state comprises a background state and a display state;
after the page state of the original tag page is changed from the display state to the background state, suspending the media resource playing process in the original tag page, and releasing the associated memory resources occupied by the media resource playing process.
According to the technical scheme, the method for playing the multi-tab media assets of the browser provided by the embodiment can monitor the page state of the original tab after the user controls the newly-built tab. After the page state of the original tag page is changed from the display state to the background state, the media resource playing process in the original tag page can be paused, and the associated memory resources occupied by the media resource playing process are released. According to the method, when a plurality of tag pages exist in the browser at the same time, the mutual influence of media assets played in the tag pages is relieved by suspending the media asset playing process, meanwhile, the occupation of the media asset playing process in the original tag page to the running memory space is reduced by releasing the associated memory resources corresponding to the playing process, the display and operation fluency of the browser is improved, and the user experience is enhanced.
