The user representation may include: user gender, user preference parameters, etc.
And step 12, sending the high-definition screenshots of the multiple visual angles to client equipment.
In the step, the high-definition screenshots of the multiple visual angles are sent to the client device, so that the client device displays the high-definition screenshots of the multiple visual angles for the user to select.
In the embodiment of the invention, when a user triggers a screen capture function through client equipment, a screen capture request is sent to a back-end service platform instead of a screen capture completed on the client equipment, and the back-end service platform obtains high-definition screen captures of a plurality of visual angles according to priority information under the condition of receiving the screen capture request sent by the client equipment; and sending the high-definition screenshots of the multiple visual angles to the client equipment so that the client equipment can display the high-definition screenshots of the multiple visual angles for the user to select and use. Therefore, by using the scheme of the embodiment of the invention, the user can obtain multi-angle high-definition screenshots at the same moment, thereby avoiding missing wonderful live broadcast pictures and simultaneously avoiding the problem of unclear screenshot images when the screenshots are carried out based on the capacity of the client equipment.
In an embodiment, before step 11, the method further includes:
the method comprises the steps of obtaining a high-definition picture set of a plurality of view angle key frames corresponding to a live video stream, and storing the high-definition picture set according to the current absolute time.
For example, after receiving a live signal, the back-end service platform stores the live signal and a live video stream in a video slice form, analyzes the live signal, converts a keyframe I frame corresponding to the live video stream into a high-definition picture, and stores the high-definition picture according to current absolute time so as to facilitate indexing.
Further, the storing the high definition picture set according to the current absolute time includes:
and classifying and storing the high-definition picture set according to the current absolute time according to the program ID corresponding to the live video stream.
Illustratively, the storage format may be as follows:
in the above embodiment, the content IDs of the programs are used as categories, different views of the same program content are used as a group of live broadcasts, and the live broadcasts are managed in a unified manner in the storage, so that the backend service platform can retrieve the screenshots based on the storage format when receiving the screenshooting request, so as to obtain the multi-view high-definition screenshots corresponding to the screenshooting request.
In an embodiment, the acquiring positions of the high definition screenshots of the plurality of view angles include: the step 11 mainly includes the following two situations:
the first condition is as follows: when the priority information indicates that the priority of the back-end service platform is the highest, directly acquiring the high-definition screenshots of the multiple visual angles from the back-end service platform; the back-end service platform stores a high-definition picture set of a plurality of view angle key frames corresponding to live video streams, and the high-definition picture set is stored according to current absolute time;
specifically, directly obtain the high definition screenshot of a plurality of visual angles from the back-end service platform, include:
acquiring a first screenshot combination from the high-definition picture set stored by the back-end service platform, wherein the first screenshot combination is a high-definition screenshot of a plurality of visual angles corresponding to the screenshot request;
determining the first screenshot combination as a high-definition screenshot of the plurality of perspectives;
the plurality of visual angles are all visual angles comprising key information in a screenshot main picture, and the screenshot main picture is a screenshot picture of a user on the client device.
In the embodiment, based on the screen capture request sent by the client device, the back-end service platform analyzes the screen capture request to obtain the contents such as the program ID watched by the user, the time for triggering the screen capture, the key elements in the screen capture picture of the user, the user preference and the like; according to the analyzed content, a multi-angle group of the live broadcast program can be positioned through the program id, and the multi-angle group contains the set information of elements of video information, audio information and image information of multiple angles of live broadcast; and further finding a high-definition picture set corresponding to the screen capture request, and acquiring high-definition screenshots (a first screenshot combination) of a plurality of visual angles containing key information from the stored high-definition picture set.
Case two: and when the priority information indicates that the priority of the CDN is the highest, preferentially acquiring the high-definition screenshots of the multiple view angles stored in the CDN.
Specifically, preferentially acquiring high-definition screenshots of multiple views stored in the CDN includes:
receiving a retrieval result sent by a Content Delivery Network (CDN); the search result is obtained by the CDN according to the screenshot request, and the search result is used for indicating whether a high-definition screenshot of a target view angle is stored in the CDN;
acquiring high-definition screenshots of a plurality of visual angles according to the retrieval result;
wherein the target view is any one or more of the plurality of views; the plurality of viewing angles are all viewing angles comprising key information in a screenshot main picture, and the screenshot main picture is a screenshot picture of a user on the client device.
In this embodiment, the screen capture request triggered by the c-end user is transmitted to the background service platform through the CDN. And when the CDN receives the screen capture request, the CDN also searches whether the high-definition screenshot of the target view angle is cached locally in a local resource management platform of the CDN according to the screen capture request, generates a search result and then sends the search result to a back-end service platform, and the back-end service platform judges the acquisition position of the high-definition screenshot of the target view angle according to the search result, so that the high-definition screenshots of a plurality of view angles are acquired. Thus, the processing efficiency can be improved.
Further, the acquiring high-definition screenshots of multiple viewing angles according to the retrieval result includes:
acquiring a first screenshot combination from the high-definition picture set stored by the back-end service platform, wherein the first screenshot combination is a high-definition screenshot of a plurality of visual angles corresponding to the screenshot request;
determining the first screenshot combination as a high-definition screenshot of the multiple viewing angles under the condition that the retrieval result indicates that a second screenshot combination is not stored in the CDN;
under the condition that the retrieval result indicates that the second screenshot combination is stored in the CDN, comparing the first screenshot combination with the second screenshot combination, and determining high-definition screenshots of the multiple viewing angles according to the comparison result;
the second screenshot combination is a high-definition screenshot of a plurality of view angles stored in the CDN within a first preset time period, and the first preset time period is a preset time period before and/or after the trigger time of the screenshot request.
In this embodiment, the screen capture request triggered by the c-end user is transmitted to the background service platform through the CDN. And when the CDN receives the screen capture request, searching whether a second screen capture combination is cached locally in a resource management platform of the CDN according to the screen capture request, wherein the second screen capture combination is a high-definition screen capture of a plurality of visual angles captured and stored in the CDN by other users in a first preset time period. And when the second screenshot combination is cached, sending a retrieval result comprising the second screenshot combination to the back-end service platform, and when the second screenshot combination is not cached in the CDN, sending a retrieval result indicating that the CDN does not comprise the second screenshot combination to the back-end service platform. Further, the back-end service platform needs to determine the first screenshot combination as the high-definition screenshots of the multiple viewing angles when receiving a retrieval result indicating that the CDN does not include the second screenshot combination; and under the condition that a retrieval result comprising a second screenshot combination is received, comparing the first screenshot combination with the second screenshot combination, and determining the acquisition modes of the high-definition screenshots corresponding to different viewing angles according to the comparison result.
In an embodiment, the comparing the first screenshot combination with the second screenshot combination, and obtaining the high definition screenshots of the multiple viewing angles according to the comparison result includes:
judging whether the second screenshot combination comprises a high-definition screenshot of a target view angle;
if yes, acquiring a high-definition screenshot of the target view angle from the second screenshot combination; otherwise, acquiring a high-definition screenshot of the target view angle from the first screenshot combination; wherein the target view is any one or more of the plurality of views;
in this embodiment, the size of the super-definition image is large due to the live source stream with the screenshot picture of 4k, 8k or even 12k definition. To speed up the image download, this embodiment preferentially chooses the image that has completed the speed reduction in the CDN as the super-clean image sent to the c-end user. For example, if a high-definition screenshot corresponding to a certain view angle corresponding to the screenshot request is cached in the CDN, the high-definition screenshot cached in the CDN at the view angle is sent to the client device; and when it is determined that there is no high-definition screenshot corresponding to a certain view angle in the CDN, acquiring the high-definition screenshot corresponding to the view angle from the first screenshot combination stored in the back-end service platform. Therefore, the accelerated downloading of partial pictures can be facilitated, and the speed of downloading the pictures can be improved.
In another embodiment, the acquiring high definition screenshots of multiple viewing angles further includes:
and acquiescently obtaining a high-definition screenshot corresponding to the first visual angle from a first screenshot combination.
For example, assuming that there are n different views in the live broadcast, the recommended image pic-out to the user is the output image information chain, and the selection weight algorithm is:
Pic-out1＝Pic-c1
loop (i ═ 2; i < n (total number of angles); i + +)
If Pic-ti is 1 (If pit-ti in CDN)
Pic-outn＝pic-ti
Else
Pic-outn＝pic-ci
Wherein, Pic-c1 is a high-definition screenshot corresponding to a first view angle (for example, i is 1, the view angle corresponding to the user screenshot home screen) stored in the backend service platform; pic-ti is a high-definition screenshot corresponding to a view angle i (i is more than or equal to 2) cached in the CDN; and pic-ci is a high-definition screenshot corresponding to the view angle i (i is more than or equal to 2) stored in the back-end service platform.
In this embodiment, since the high definition screenshot cached in the CDN may not completely correspond to the user screenshot home picture, the high definition screenshot corresponding to the default user screenshot home picture is obtained from the high definition picture set stored in the back-end service platform based on the definition weight, and the high definition screenshot corresponding to another view is preferentially obtained from the CDN cache.
Further, in the first and second cases, the obtaining a first cut-and-map combination from the high-definition picture set stored in the backend service platform includes:
according to the screen capture request, determining a high-definition picture combination corresponding to a first visual angle and a high-definition picture combination corresponding to a second visual angle from a high-definition picture set stored by the back-end service platform; the first visual angle is a visual angle corresponding to the screen capture main picture, and the second visual angle is the rest visual angles except the first visual angle in the plurality of visual angles;
determining a high-definition screenshot corresponding to the first visual angle from a high-definition picture combination corresponding to the first visual angle, and determining a high-definition screenshot corresponding to the second visual angle from a high-definition picture combination corresponding to the second visual angle;
and taking the high-definition screenshot corresponding to the first visual angle and the high-definition screenshot corresponding to the second visual angle as the first screenshot combination.
Wherein, the high definition picture combination corresponding to the first visual angle comprises: high-definition pictures at the first visual angle corresponding to the trigger time of the screen capturing request and high-definition pictures at the first visual angle in a second preset time period; the second preset time period is a preset time period before or after the trigger time of the screen capture request.
Wherein, the high definition picture combination corresponding to the second visual angle comprises: the high-definition pictures at the second visual angle corresponding to the trigger time of the screen capturing request and the high-definition pictures at the second visual angle in a third preset time period; the third preset time period is a preset time period before or after the trigger time of the screen capture request.
For example, the acquiring of the high definition screenshot corresponding to the first view angle may specifically include:
and A1, acquiring a high-definition screenshot main picture corresponding to the screenshot main picture of the current user on the client equipment from the stored high-definition picture set based on the screenshot request sent by the client equipment. For example, assuming that the view angle of the screenshot main picture on the client device of the user is angle-1 (first view angle) and the screenshot time is now1, the high definition picture corresponding to the first view angle at the screenshot request trigger time can be located in the stored high definition picture set according to the screenshot request and is pic 1; time backtracking is performed (for example, 5 seconds) in the first view based on the trigger time of the screen capture request, and if 24 frames per second (the specific number of frames can be determined according to the frame rate), 5 × 24 high definition pictures (i.e., a high definition picture combination corresponding to the first view) can be obtained.
Step A2: through an artificial intelligence image recognition algorithm, the 5 × 24 high-definition pictures at the first view angle are respectively analyzed, and a high-definition picture with the clearest picture quality or the best picture content is obtained and is used as a high-definition screenshot corresponding to the first view angle (for example, closed eyes are cancelled or the image is unclear as much as possible).
For example, the acquiring of the high definition screenshots corresponding to the other viewing angles (the second viewing angle) may specifically include:
and B1, acquiring a high-definition screenshot main picture corresponding to the screenshot main picture of the current user on the client equipment from the stored high-definition picture set based on the screenshot request sent by the client equipment. For example, assuming that the perspective of the screenshot main picture on the client device of the user is angle-1 (first perspective) and the screenshot time is now1, the high definition picture can be located in the stored high definition picture set to be pic1 according to the screenshot request; the picture content of pic1 is further analyzed to extract key elements. Such as key information (e.g., soccer) including major face information and key elements. Based on the key information, other various views (second views) including the key information are found, and time backtracking is performed based on the trigger time of the screen capture request at the corresponding views (for example, 5 seconds), and assuming that 24 frames per second (the specific number of frames can be determined according to the frame rate), 5 × 24 high-definition pictures (i.e., a high-definition picture combination corresponding to the second view) can be obtained.
Step B2: through an artificial intelligence image recognition algorithm, the 5 × 24 high-definition pictures at the second viewing angle are respectively analyzed, and a high-definition picture with the clearest picture quality or the best picture content is obtained and is used as a high-definition screenshot corresponding to the second viewing angle (for example, closed eyes are cancelled or the image is unclear as much as possible).
In an embodiment, the method further comprises:
acquiring key information included in a screenshot picture of a user on client equipment according to the screenshot request;
acquiring a high-definition picture set and/or a video clip set related to the key information;
and sending the high-definition picture set and/or the video clip set to a client device.
For example, when a user captures a picture, the key information of the picture captured by the user is determined to include Meixi shooting through artificial intelligence analysis, and the back-end service platform can recommend the Meixi ultra-high-definition gallery and the video section collection for the user. Therefore, when the user triggers the screenshot, the user can be recommended based on the user preference, and the user experience is improved.
Referring to fig. 2, it is a flowchart of a screenshot method provided in an embodiment of the present invention, where the method is applied to a client device, and includes the following steps:
for example, when a user watches a ball game live broadcast on a client device and sees a fine color screen, the user triggers a screen capture request input based on a screen capture function of the client device, and the client device sends a screen capture request to a back-end service platform when detecting the screen capture request input.
Specifically, the screenshot request triggered by the user is transmitted to the background service platform through the CDN acceleration.
Wherein the screen capture request includes at least one of the following information:
triggering time of the screen capture request;
a program ID;
a program name;
playing the address information;
a perspective of a user's screenshot on the client device;
key information of a user within a cut-out on the client device;
a user represents a representation.
The key information of the user in the screenshot on the client device may include key characters, key objects, and the like, for example, when the game is played directly, key elements such as face information and football in the screenshot of the user. The user representation may include: user gender, user preference parameters, etc.
when the multi-station live broadcasting is adopted in activity sites such as a ball game, a concert and the like, the shooting visual angles corresponding to different stations are different, the multiple visual angles comprise the shooting visual angles corresponding to different stations, and the shooting pictures at each visual angle are different.
And step 23, displaying the high-definition screenshots of the multiple visual angles.
Illustratively, as in fig. 3, there is shown a display screen displaying high definition screenshots of the plurality of perspectives, for example as in fig. 3, the high definition screenshots of the plurality of perspectives comprise: first perspective screenshot, second perspective screenshot … … eighth perspective screenshot. Therefore, the user can select the screenshots with different viewing angles as required, and the operations of deleting, saving, sharing and the like are performed, so that the user can use the screen shots conveniently.
According to the scheme, the capacity of directly accessing the back-end service platform from the c-end user through capacity penetration is achieved, and therefore ultrahigh-definition images of multiple visual angles based on live source screenshots are obtained. Therefore, with the video becoming clearer, the 4k live broadcast and even the 8k live broadcast can directly provide ultra-high-definition picture information for the c-end user, and the user does not need to be limited by the pixel of the mobile phone.
A specific embodiment of the screenshot method is described below with reference to fig. 4. The method mainly comprises the following steps:
step 1, the back-end service platform analyzes the live broadcast signal, converts the key frame I frame of the live broadcast stream with a plurality of visual angles into picture information, and stores the picture information according to the current absolute time.
Specifically, as shown in fig. 4, the back-end service platform includes an analysis processing module, a Streaming media analysis unit (Streaming), and three modules. Wherein the content of the first and second substances,
an analysis processing module: and receiving a screenshot command of a user, analyzing and processing the screenshot request, and returning a processing result.
Streaming: the system is used for receiving the highest-definition video stream transmitted from the front-end competition field or the activity field, and capturing the video stream according to the key frame and storing the video stream. Specifically, Streaming receives a live signal and stores the live signal in a video slice in storage. Meanwhile, the direct broadcast signal is analyzed, the key frame I frame is converted into picture information and stored in a storage, and meanwhile, the picture is stored according to the current absolute time.
A storage module: for storing live signals and live-based key frame screenshot information. And during storage, classifying and managing the stored content according to the content id of the live broadcast program. Specifically, different viewing angles of the same program content (match or singing) are used as a group of live broadcasts and are managed in a storage uniformly. The memory structure is as described above.
And 2, watching the video through the c-end playing terminal (client equipment), clicking a screen capture button in the client when the interesting content appears, and sending a capture instruction (capture request) to the back-end section service platform by the client.
And 3, when receiving a screen capture request sent by a user, the back-end service platform searches the corresponding multi-view high-definition pictures in the storage according to the definition weight and the CDN weight.
Specifically, the c-end user triggers the screenshot function and sends an instruction (screenshot request) to the analysis processing module. And processing by an analysis processing module.
Wherein the instructions include:
{
time frame (trigger time of screen capture request)
[ CONTENTID ] PROGRAM ID
[ CONTENtNAme ] program name
Play-url playing address information
[ angle ] perspective definition (perspective of user's screenshot on the client device)
[ KEYCONTENG ] Key content (Key information in the cross-sectional picture of the user on the client device)
Personals user representation
……
}
After receiving the screen capture request of the user, the analysis processing module analyzes the capture instruction to obtain the program ID watched by the user, the time for triggering the screen capture, the key information in the screen capture, the preference of the user and the like. Further, the analysis processing module starts to quickly retrieve the content in the storage based on the effective information.
Firstly, positioning a multi-angle group of live programs through program IDs, wherein the multi-angle group comprises live video information, audio information and set information of elements of image information from multiple angles; then finding an ultra-high-definition image group; and finding the ultrahigh-definition images corresponding to the multiple visual angles through a recommendation algorithm.
The recommendation algorithm is mainly based on the definition weight "C" and CDN weight value "T" of the picture.
The following introduces a sharpness algorithm, which mainly includes the following steps:
step a1, based on the screen capture request transmitted by the c-end user, the high definition screenshot main picture corresponding to the current user can be found in the storage. Eg: assuming angle-1 and the screenshot time is now1, the screenshot main picture viewed by the user can be located in the storage according to the transmitted information and is pic 1.
Step a2, the analysis processing module finds the main picture c1 currently seen by the user, and then analyzes the picture to extract key elements. Such as main human face information, key element information (soccer, etc.). In order to ensure that the content of the high-definition image sent to the c-end user is optimal, the time backtracking of the key information needs to be carried out for 5 seconds based on the ai capability, and if 24 frames per second (24 is variable and is determined according to the frame rate), the pictures are analyzed through ai in 5x24 pictures. Such as user face information, the image information with the clearest picture quality or the best picture content is selected according to the image recognition algorithm of ai. (e.g., to try to eliminate eye closure or image blurring).
Step a3, other visual angles are also selected according to the main content of the user, 5x24 pictures (24 variable and determined according to the frame rate) are obtained by backtracking for 5 seconds, namely, the information of the pictures and key elements are used for backtracking forwards, and the content with the clearest image quality is selected.
Step a4, the data processing platform records the pictures with the optimal quality and content selected by operation in the storage corresponding to different visual angles to obtain pic-c1 to pic-cn corresponding to different visual angles.
The following description of the CDN weight value "T" mainly includes the following steps:
in step b1, the screen capture request transmitted from the end user c is transmitted to the analysis processing module DE through CDN acceleration. Eg: assuming angle-1, the screenshot time is assumed to be now1, according to the transmitted screenshot request, while the CDN platform transmits the screenshot request to the analysis processing module for local search, the CDN also locates, through its own resource management platform, the program within the screenshot time period of the user (default 5S) according to information such as content, playlist, timestamp, and the like in the screenshot request, and retrieves whether another user performs screenshot, and stores the screenshot image in the CDN.
And b2, if the screenshot operation of other users in the period of time cannot be retrieved, the weight 'T' is 0, and the image information found in the analysis processing module is mainly sent to the user at the c end.
In step b3, if it is found in the CDN that there are other users performing screenshot operations within a specific time (within default 5s), the graphics stored in the CDN will be used from 'pic-t 1' to 'pic-tn'.
And b4, the CDN sends the retrieval result to an analysis processing module.
And b5, comparing the locally retrieved pic-cn with the pic-tn retrieved by the CDN in the analysis processing module, and directly adopting the image which is cached in the CDN after being changed in the same view angle if the pic-tn based on angle-n already exists in the CDN. And if the pic-tn based on the angle-n of the view cannot be found in the CDN, selecting a locally stored pic-cn image for the angle-n, sending the pic-cn image to a c-end user, and caching and accelerating the pic-cn by the CDN platform. In the step, pic-cn is a high definition screenshot corresponding to angle-n (view n) stored in the back-end service platform; pic-tn is a high-definition screenshot corresponding to angle-n (view angle n) stored in the CDN;
and 4, the analysis processing module sends the found high-definition screenshot atlas of the multiple visual angles back to the client of the c-end user for display. The user can select the interested pictures according to the received image information and store the pictures to the local.
In the embodiment, based on the image recommendation algorithm of the definition weight and the CDN weight, the c-end user can directly obtain the ultra-high definition screenshots of multiple views of the live source screenshot. The method and the device can enable the user to obtain multi-angle high-definition screenshots at the same moment, avoid missing wonderful live broadcast pictures, and simultaneously avoid the problem that the screenshot images are not clear when the screenshots are performed based on the capacity of the client equipment.
