Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described below in detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order; also, the embodiments and features of the embodiments in the present disclosure may be arbitrarily combined with each other without conflict.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of explanation of the present disclosure, and have no specific meaning in themselves. Thus, "module", "component" or "unit" may be used mixedly.
The current 5G network live broadcast mode is the same as the existing network live broadcast, generally is broadcast live broadcast, and can not distinguish participated objects to select watching objects respectively. Once live broadcasting is carried out, all people watching the live broadcasting can see the whole live broadcasting process at the same time, the watched live broadcasting contents are consistent, and due to the fact that a user cannot adjust the video progress and the video contents in the live broadcasting process, if the user wants to watch the live broadcasting contents of the heart instrument of the user, the user needs to wait for a long time, and related live broadcasting contents can be missed, and user experience is affected. For example, when a student queues up to receive vaccination in a school, a parent wants to observe the vaccination situation of children at home through a live broadcast platform, and the parent cannot efficiently observe the vaccination situation of children due to the fact that live broadcast videos cannot distinguish live broadcast objects.
In order to realize the purpose of pushing specific video content to a specific user in the related art, the video is generally pushed to the user in a recorded broadcast form: at first, record live video content, then at artifical or automatic segmentation, send each segmentation respectively to corresponding personnel, the process is not only loaded down with trivial details for this mode, has increased extra cost, and has certain time delay nature, and the user watches video through live broadcast form's main objective just can watch the video in the very first time, consequently, has also violated user's original intention with recorded broadcast form propelling movement video.
In order to solve the above problems, the embodiments of the present disclosure provide a video push method based on 5G live broadcast, in which video key information provided by a live broadcast requester is obtained through an Application Function (AF), in a live broadcast video stream, content currently appearing in a video frame is automatically matched with the video key information provided by the live broadcast requester, and after the video key information is matched, a corresponding video code stream is pushed to the live broadcast request method, so that a purpose of pushing specific live broadcast video content to a specific object can be achieved, a specific user does not need to push the specific live broadcast video content in a recorded broadcast manner, the specific user can efficiently view the specific live broadcast content that the user wants to view in the live broadcast process, and live broadcast experience of the user is improved.
Referring to fig. 1, fig. 1 is a flowchart illustrating a video push method based on live broadcast according to a first embodiment of the present invention, where the method is applied to an application function entity and includes steps S101 to S103.
In step S101, first video key information provided by a first live requester is acquired.
The first video key information comprises any one or any combination of images, characters and voice.
It is to be understood that the image may be a photograph of a specific object that a user wants to watch, the text may be subtitle information in a picture, and the voice may be voice information indicating that a name of a specific object appears in a video, which is not particularly limited in this disclosure.
For example, a user only wants to watch a video of a specific participant in a live art program, the user can upload an avatar of the specific participant as video key information to order a live video, and when a matching content appears in a video picture, the video content is pushed to the user.
In step S102, matching a video code stream in live broadcast based on the first video key information.
In step S103, after a first video code stream corresponding to the first video key information is matched, the first video code stream is pushed to the first live requesting party.
Compared with the prior art, the same live broadcast video is pushed to unspecified people, or the video is segmented in a recorded broadcast mode and then sent to the specific user, the push of the specific live broadcast content of the specific user is realized based on the video key information, the problems that the user cannot adjust the video progress and the video content in the live broadcast process, long waiting time is needed if the user wants to watch the live broadcast content of the self-psychograph, the related live broadcast content is possibly missed and the like are solved, meanwhile, the live broadcast delay problem does not exist, and the live broadcast watching experience of the user is improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating a live video push method according to a second embodiment of the present disclosure, where on the basis of the first embodiment, the present embodiment facilitates a live video push management process by establishing a video subscription list, and specifically, the present embodiment further includes steps S201 to S204 compared with the previous embodiment.
In step S201, a video subscription list is established, where the video subscription list includes each live requesting party and video key information provided by the live requesting party, and each live requesting party is associated with the video key information provided by the live requesting party;
before pushing the first video code stream to the first live requesting party (step S102), the method further includes:
in step S202, a first identity of a first direct broadcast requester is obtained.
Specifically, the first identity identifier is used for verifying the identity of the user, and the first identity identifier may appear in the form of a mobile phone number of the user, and associates the mobile phone number of the user with the video key information requested by the mobile phone number of the user by acquiring the mobile phone number of the user.
It should be noted that step S202 and step S101 may be performed synchronously, and the present disclosure does not limit the sequence of step S101 and step S102.
In step S203, it is queried in the video subscription list whether the first video key information exists, if not, step S204 is executed, otherwise, the process is ended, which indicates that the video content has been subscribed by other users, the process is ended, and a prompt message indicating that the video subscription fails may be returned at the same time.
In step S204, the first identity identifier and the first video key information are stored in the video subscription list in an associated manner, and step S102 is executed to push a first video stream to the first live requesting party after the first video stream corresponding to the first video key information is matched.
It should be noted that, if the form of the user mobile phone number is used as the identity identifier, since it is possible that the same user has two mobile phone numbers, when it is found that the first video key information exists, in the scene, it may be first queried from an operator BSS (Business support system) whether the mobile phone number associated with the first video key information in the video subscription list and the mobile phone number currently initiating the request are the same user, specifically, it may be determined whether the identity cards of the registered mobile phone numbers are consistent, if the user is the same user, it is described that the user has subscribed the video, at this time, a predetermined prompt may be initiated to the user, and step S102 is executed to push a corresponding video stream to the user, and if the user is not the same user, the process is ended, and a prompt information that the video subscription fails may be returned.
It can be understood that the method provided by this embodiment is mainly directed to pushing a live specific video stream to a specific object only, and in some embodiments, if a user subscribes to specific content in a certain live video stream in a shared manner, it is not necessary to query whether the video key information exists in a video subscription list, or after querying that the video key information exists, determine that a currently requested live requesting party is one of shared users, so as to further achieve the purpose that the user views the same specific content in live in a shared manner.
Referring to fig. 3, fig. 3 is a flowchart illustrating a live broadcast-based video push method according to a third embodiment of the present disclosure, where on the basis of implementing the first embodiment, the present embodiment may respectively push different video code streams for different users at the same time by continuously matching the second video key information and pushing the second video code stream to the second live broadcast requester, so as to further improve user experience, and specifically, compared with the first embodiment, the method further includes steps S301 to S303.
In step S301, second video key information provided by a second live broadcast requester is acquired;
in step S302, matching the video code stream in live broadcasting based on the second video key information while pushing the first video code stream to the first live broadcasting requester; and the number of the first and second groups,
in step S303, after a second video code stream corresponding to the second video key information is matched, the second video code stream is pushed to the second live broadcast requester.
Further, in some specific scenes, users want live video to be pushed exclusively, especially in scenes in which multiple objects enter a specific location one by one in a continuous manner and then leave the specific location within the live video, and users want only a limited observer to be able to see the live video of the specific object appearing at the specific location when the specific object appears in the picture, so that relative privacy of the specific object or specific content in the live video can be protected while the live requirements of the users are met. For example: the students are queued to receive the vaccination, or the elderly are queued to draw blood during physical examination, and the like. Under these scenarios, students or the family members of the elderly who have received physical blood draws may need to view the real-time situation as bystanders, but often cannot be physically present, and the video live of the first is obviously not desired to be seen by the family members of the second.
In order to achieve the above-mentioned purpose that only a certain viewer can see a live video of a certain object appearing in a picture, a live video pushing method is further provided in a fourth embodiment of the present disclosure, on the basis of the third embodiment, the present embodiment stops a video pushing state corresponding to current video key information in time when other video key information is matched, so as to prevent the current user from viewing the video content subscribed by the other user, specifically, as shown in fig. 4, after step S302 and before step S302, step S401 is further included.
In step S401, the first video stream is stopped from being pushed to the first broadcast requester.
It can be understood that, in this embodiment, mainly for a scene in which a plurality of objects in a live video enter and leave a specific location one by one in a continuous manner, when other video key information is matched, a video object corresponding to current video key information usually leaves, but a server in the related art usually cannot turn off live video in time, live video is usually pushed to a current user, and in order to solve such a problem, the privacy of a video object corresponding to other video key information is guaranteed, in this embodiment, the video is first stopped being pushed to the current user, and then other video key information is pushed to other users, where the other users are providers of the matched other video key information.
Further, in this embodiment, after obtaining the second video key information provided by the second live broadcast requester, first, whether the second video key information already exists may be queried in the video subscription list, if the second video key information does not exist, the second video key information and the second live broadcast requester are stored in the video subscription list in an associated manner, and when the system matches the second video key information, the push to the first live broadcast requester is stopped, and a second video code stream corresponding to the second video key information is pushed to the second live broadcast requester.
For further understanding of the present disclosure, with reference to fig. 5, a fifth embodiment of the present disclosure provides a live broadcast-based video push method in a 5G network environment, where a session is established and video push is implemented based on interactions among functional entities in a 5G network, and specifically, the method includes the following steps: . (1) A User sends to an AF through a UE (User Equipment): the method comprises the steps of presetting program names, video key information in programs and own mobile phone numbers.
a) The video key information may be an image, for example, in a scene for a student to be vaccinated, the head portrait of the student to be vaccinated is uploaded, and the user uploading the head portrait is the parent of the student.
(2) After receiving the request sent by the UE, the AF first queries whether the same key information has been reserved by other users in an information list that has been reserved by other users.
a) If the same key information is found to exist already, and the mobile phone number submitting the information is different from the mobile phone number of the current user, inquiring whether the two mobile phone numbers belong to the same (identified by the identity card) user or not from the operating BSS system. If yes, replacing the order relation with the mobile phone number submitted at this time, and executing the step (3); if not, returning the preset failure to the UE, and ending the process.
b) And (4) if the same video key information is not found, executing the step (3).
(3) And storing the current preset information into a preset information list, and returning the successful ordering to the user.
(4) When the live video system starts to collect live scene images, sending a notice to AF: live broadcasts are about to start, including the name of the live program about to start (e.g., xxx elementary school grade x class xxx vaccine injection site).
(5) And after receiving the notification from the video live broadcast system, the AF finds a corresponding preset information list according to the live broadcast program name, and finds all preset mobile phone numbers from the preset information list. The UDM (Unified data management function) then initiates a connection pre-establishment request for these numbers.
(6) And the UDM respectively initiates a session connection pre-establishment request to the AMF where the UE corresponding to each number is currently located.
(7) The AMF (Access and Mobility Management Function) allocates an SMF to be responsible for the subsequent session Management.
(8) The SMF (Session Management Function) allocates an UPF (user plane Function) to be responsible for carrying subsequent video media streams. And simultaneously returning a session pre-establishment success message to the UDM.
(9) And after receiving the session pre-establishment success message, the UDM informs the AF of successful pre-connection establishment. The corresponding relation between the SMF and the UE number is included, namely, each mobile phone number is respectively responsible for session management by the SMF.
(10) The SMF sends the "UPF entry address, access control information for the UPF (e.g. access authorization code, which can be understood as a form of password), the number of the UE using the UPF to the AF,
(11) the AF establishes a data path connection with the UPF (but does not camp on bandwidth).
(12) And the video live broadcast system sends the live broadcast video stream to the AF after formally starting live broadcast.
(13) The AF identifies the video images in the video stream in real time, and extracts the mobile phone number matched with the corresponding predetermined relationship (key information in the program, mobile phone number).
(14) And pushing the live broadcast video stream to the UPF corresponding to the successfully matched UE number.
(15) And sending a link formal establishment request to the UDM, requesting to establish the connection relation of the matched UE.
(16) And the UDM initiates a connection establishment request to the AMF where the UE is currently located.
(17) The AMF sends a link establishment request to the UE, and simultaneously sends a session establishment command to the SMF.
(18) The SMF sends a session setup notification to the AF.
(19) The SMF sends a push video stream command to the UPF.
(20) And the UPF pushes the video stream to the corresponding UE according to the command of the SMF. So far, the user holding the UE can see the expected live video content.
(21) The AF always performs real-time matching on the content in the video in real time.
a) When a new matching object is found, step (13) is repeated and step (22) is performed.
b) When the video stream is finished, step (22) is performed.
(22) The SMF session is notified of the termination.
(23) The SMF sends a stop video stream push command to the UPF.
(24) The UPF stops pushing the current video stream.
(25) The SMF sends a session termination command to the AMF.
(26) The AMF informs the UE of the session termination. And ending the live program scheduled to be watched by the user holding the UE.
In connection with the above-mentioned second embodiment, whether to subscribe in a sharing manner is mentioned, and the above-mentioned flow is used as a basic subscription and does not relate to the sharing manner subscription. Further, if a user subscribes to a particular segment in a live video stream in a shared manner: step (2) does not need to be executed after step (1) is executed, and step (3) is directly entered. The difference between the video subscription in the shared manner and the basic subscription is that only one UE receives a video stream at the same time in the basic process, while multiple UEs may receive the same video stream through multiple different UPFs in the shared manner, and in step (21), the AF does not check whether a change of a matching object occurs by itself, but sends a program switching notification message to the AF by the video live broadcast system, indicating that the previous program of the AF has ended and the next program is about to start.
Other descriptions:
(A) in step (1), the connection mode between the UE and the AF is a common data connection, such as wifi or a data connection based on a mobile communication network. This is prior art.
(B) In step (1), the UE may use a specific client application to establish a connection relationship with the AF, or may use a browser to establish a connection relationship with the AF. Regardless of the connection relationship established in that way, for security reasons, the user image uploaded by the UE will be shot on site and cannot be called from the original photo library of the mobile phone or from other applications. This is the prior art and will not be described in detail here.
