Referring to fig. 1, a schematic structural diagram of a live broadcast system provided in an embodiment of the present application is shown, where the live broadcast system includes a cloud platform server 100, a first terminal 101, and a second terminal 102, and the first terminal 101 and the second terminal 102 are respectively in communication connection with the cloud platform server 100.
In this embodiment, the second terminal 102 is a live broadcast terminal and includes a display interface, a camera assembly, and the like, and a user performs live broadcast recording on the second terminal 102. The first terminal 101 is a playing end of live video, and may be an intelligent device such as a mobile phone and a computer, and a user watches the live video on the first terminal 101. The cloud platform server 100 caches live data of the second terminal 102 and sends the live data to the first terminal 101, so that a live video is played in a display interface of the first terminal 101.
For example, in the live broadcast teaching process, a teacher live broadcasts at the second terminal 102, the cloud platform server 100 caches blackboard-writing pages in the live broadcast teaching, the first terminal 101 obtains the blackboard-writing pages of the cloud platform server 100 and displays the blackboard-writing pages in a display interface, and students watch the live broadcast teaching on the display interface of the first terminal 101. In order to explain the technical means of the present application, the following description will be given by way of specific examples.
Example one
Referring to fig. 2, a schematic flow chart of a caching method for a live video page provided in an embodiment of the present application is shown, where the method includes:
step S11, acquiring at least one display page in the live video, and caching the at least one display page;
in this embodiment of the application, the obtaining of the at least one display page in the live video and the caching of the at least one display page may be that the cloud platform server 100 intercepts and caches a page displayed on the display interface of the second terminal 102 at regular time during live broadcasting.
For example, when the second terminal 102 plays the live broadcast, the cloud platform server 100 intercepts the display interface of the second terminal 102 every minute, generates a picture, and caches the picture in the cloud platform server 100.
In this embodiment of the application, the obtaining of the at least one display page in the live video and the caching of the at least one display page may also be performed by intercepting a page after change and caching the page when it is recognized that the page displayed on the display interface of the second terminal 102 changes.
For example, when the second terminal 102 broadcasts directly, the user performs a related operation in the second terminal 102 to change a page displayed on a display interface of the user, and the cloud platform server 100 intercepts the display interface of the second terminal 102 once in response to the operation of the user, generates a picture, and caches the picture in the cloud platform server 100.
Step S12, determining a target page when a first instruction sent by the first terminal is received, where the target page includes a display page corresponding to the first instruction in at least one display page, and the first instruction is an instruction sent by the first terminal 101 in a process of playing a live video;
in this embodiment, when the first terminal 101 plays a live video, a page of the live video displayed on a display interface of the first terminal is synchronized with a page of the live video displayed on a display interface of the second terminal 102 in real time when the live video is live. The first instruction is an instruction generated by the first terminal receiving a relevant operation of a display page in the live video before a user requests to review the live video in the process of playing the live video, and the first terminal 101 sends the first instruction to the cloud platform server 100.
In this embodiment, the cloud platform server 100, in response to the first instruction, determines, from at least one cached display page, that a display page corresponding to the first instruction is a target page. The target page is a display page to which an operation for a user is directed.
For example, in the process of playing a live broadcast, when receiving an operation that a user instructs to view a previous display page, the first terminal 101 sends a first instruction to the cloud platform server 100, and when receiving the first instruction, the cloud platform server 100 determines that the previous display page of a current live video page is a target page from at least one cached display page.
Step S13, sending the target page to the first terminal 101, so that the display interface of the first terminal 101 is switched from the page of the live video to the target page.
In step S13 of the embodiment of the present application, the cloud platform server 100 sends the target page to the first terminal 101, and a display interface of the first terminal 101 is switched from a page of a live video to the target page.
Through the embodiment of the application, the cloud platform server 100 can automatically cache the display pages of the live video, and determine that the target page is displayed in the display interface of the first terminal 101 from at least one cached display page according to the user requirement, that is, the user can switch the page of the live video according to the operation in the live playing process, so as to watch the previous live content, and improve the timeliness of content acquisition.
In addition, because at least one display page in the live video is cached in the cloud platform server 100, after the second terminal 102 finishes live broadcasting, the first terminal 101 can still automatically review the display page in the live video to obtain related information in time, and the timeliness of content obtaining is further improved.
Example two
Referring to fig. 3, which is a schematic flow chart of a caching method for a live video page provided in the second embodiment of the present application, when a live video is a teaching live video and each display page in at least one display page is a blackboard-writing page, the method includes:
step S21, acquiring at least one display page in the live video, and caching the at least one display page;
step S22, receiving a scene page sent by the second terminal 102, wherein the scene page is generated based on the scene information in the live broadcast process acquired by the second terminal;
step S23, determining a first page and a scene page as target pages, wherein the first page is a blackboard-writing page corresponding to a first instruction in at least one blackboard-writing page;
step S24, sending the target page to the first terminal 101, so that the display interface of the first terminal 101 is switched from the page of the live video to the target page.
Step S21 is the same as step S11, and step S24 is the same as step S13, which are not repeated herein. The difference from the first embodiment is that steps S22 to S23 are detailed as follows:
and under the condition that the live video is the teaching live video and each display page in at least one display page is a blackboard-writing page, the page of the live video also comprises a scene page besides the blackboard page. The page of the blackboard-writing can be a PPT or a captured picture of the display interface of the second terminal 102.
In step S22, the cloud platform server 100 receives the scene page sent by the second terminal 102, and may cache the scene page. When the first terminal 101 plays the live video, the first terminal can watch the blackboard-writing page displayed in real time by the live video, and can also watch the scene page when the teacher plays the live video.
The second terminal 102 generates the scene page, which may be generated when receiving a second instruction sent by the cloud platform server 100 to the second terminal 102.
For example, when a teacher live broadcasts education with the second terminal 102, students operate in the first terminal 101 to request to view scene information of the teacher live broadcasts, the first terminal 101 sends the request to the cloud platform server 100, the cloud platform server 100 generates a second instruction based on the request and sends the second instruction to the second terminal 102, in response to the second instruction, a camera of the second terminal 102 shoots scene information such as a head portrait and a background of the teacher live broadcasts, a scene page of the teacher live broadcasts is generated, and the scene page is sent to the cloud platform server 100 in real time.
The second terminal 102 generates the scene page, or may generate a second instruction based on an operation of a user when the second terminal performs live broadcasting, and the second terminal 102 generates the scene page in response to the second instruction.
For example, when the teacher live-broadcasts a teaching on the second terminal 102, the teacher clicks a record button on the display interface of the second terminal 102, and the second terminal 102 generates a second instruction in response to the operation, where the second instruction instructs the camera of the second terminal 102 to capture scene information such as a head portrait and a background of the teacher live-broadcast, and generates a scene page during live-broadcast.
In a possible implementation manner of this embodiment, the display interface of the first terminal 101 includes a first display interface and a second display interface, where the first display interface is used to display a blackboard-writing page, the second display interface is used to display a scene page, and the second display interface may be displayed in a floating window form, or may be a display interface that occupies a single area of the display screen of the first terminal 101.
In step S23, the target page includes a first page and a scene page. The first page is a blackboard-writing page corresponding to the first instruction, which is determined by the cloud platform server 100 from at least one blackboard-writing page.
In a possible implementation manner of this embodiment, after receiving the first instruction, the cloud platform server 100 determines the first page, the first display interface of the first terminal 101 is switched from the blackboard-writing page of the live video to the first page, and the second display interface of the first terminal 101 is still displaying the scene page in real time. The student can see the scene that the teacher taught when watching live teaching, effectively alleviates the sense of distance of on-line live teaching.
For example, when a student watches a live teaching video through the first terminal 101, and misses the previous teaching content due to late arrival, or when a knowledge point of the student has not fully mastered a teacher but has started the explanation of the next knowledge point, the student may operate at the first terminal 101 to request to watch a previous blackboard-writing page.
If a student requests to watch a previous blackboard-writing page, at this time, the cloud platform server 100 receives a first instruction sent by the first terminal 101, determines that the previous blackboard-writing content of the blackboard-writing page of the current live video is a first page, sends the first page to the first terminal 101, switches the blackboard-writing page in the live video from the first page, displays the blackboard-writing page in the first terminal 101 in a first display interface of the first terminal 101, and displays a live scene of a teacher in a second display interface of the first terminal 101 without switching.
EXAMPLE III
Referring to fig. 4, a schematic flow chart of a caching method for a live video page provided in the third embodiment of the present application is shown, where the method includes:
step S31, acquiring at least one blackboard-writing page in the live video, adding key value pair information to each blackboard-writing page in the at least one blackboard-writing page to obtain a modified blackboard-writing page, and caching the modified blackboard-writing page;
step S32, receiving a scene page sent by the second terminal 102, wherein the scene page is generated based on the scene information in the live broadcast process acquired by the second terminal;
step S33, under the condition that the first instruction includes the target key value pair information, determining the blackboard-writing page matched with the target key value pair information as a first page in the modified blackboard-writing pages;
step S34, determining the first page and the scene page as target pages;
step S35, sending the target page to the first terminal 101, so that the display interface of the first terminal 101 is switched from the page of the live video to the target page.
Step S32 is the same as step S22, step S34 is the same as step S24, and step S35 is the same as step S25, which are not repeated herein. The difference from the second embodiment is that steps S31 and S33 are detailed as follows:
in step S31, after acquiring the blackboard-writing pages, the cloud platform server 100 adds key-value pair information to each blackboard-writing page, obtains modified blackboard-writing pages according to the blackboard-writing pages and the key-value pair information corresponding to the blackboard-writing pages, and caches the modified blackboard-writing pages.
For example, key value pair information may be added in a form of adding page numbers, a first blackboard-writing page in the obtained live video is identified as "1", a second blackboard-writing page is identified as "2", and so on, each blackboard-writing page is identified to obtain a modified blackboard-writing page, and the modified blackboard-writing pages are cached. Corresponding key-value pair information can also be added by identifying text content in the page of the blackboard-writing. The blackboard-writing pages are classified mainly by identifying the teaching content of each blackboard-writing page.
In step S33, the cloud platform server 100 receives the first instruction sent by the first terminal 101, and determines, as the first page, a blackboard-writing page that matches the target key-value pair information indicated by the first instruction from among the cached modified blackboard-writing pages. The at least one blackboard-writing page is identified by adding the key value pair information to obtain a modified blackboard-writing page, and the modified blackboard-writing page is cached, so that the switching of the first page to the display interface of the first terminal 101 is quickly determined, the related operations of a user at the first terminal 101 are effectively reduced, and the portability of the first terminal 101 is improved.
For example, when a student plays a live video at the first terminal 101, the student wants to review a blackboard-writing page of a first page, performs a corresponding operation at the first terminal 101, the first terminal 101 generates a first instruction based on the operation and sends the first instruction to the cloud platform server 100, and the cloud platform server 100 determines, from at least one cached blackboard-writing page, that a blackboard-writing page identified as "1" is the first page.
