In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
The embodiment provides a live broadcast advertisement method, as shown in fig. 1, where the method is applied to a server, and includes:
step S101, in the process of receiving a live video stream sent by a main broadcasting end through pull streaming and forwarding the live video stream to a spectator end, detecting a starting frame and an ending frame of a key content video of the live video stream; the starting frame represents that the key content video starts to be live broadcast, and the ending frame represents that the key content video ends to be live broadcast;
step S102, if the start frame is detected, sending start prompt information to a viewer; if the end frame is detected, end prompt information is sent to a viewer end;
step S103, sending an advertisement video to the audience so that the audience can identify a received non-key content video of the live broadcast video stream according to the start prompt message and the end prompt message, and playing the advertisement video in a preset time period for playing the non-key content video; and the non-key content video is the rest videos except the key content video in the live video stream.
It should be noted that the method provided in this embodiment is particularly suitable for real-time advertisement insertion in a live video process. Specifically, the main broadcasting end records a video, and sends a live video stream to the server in real time, and the server performs start frame and end frame detection in real time and sends the detected video stream to the audience end in real time. When the server detects the start frame or the end frame, the server immediately sends the start prompt information and the end prompt information to the audience in a short time so as to enable the audience to process and play the video.
The server may be a single server, a server group, a cloud server, or the like, and is not limited herein. The audience terminal and the anchor terminal may be a smart phone, a desktop computer, a tablet computer, or the like, which is not limited herein.
The following describes in detail the specific implementation steps of the method provided by the present application with reference to fig. 1:
it should be noted that the live advertisement method provided in this embodiment is performed synchronously and continuously in the live video streaming process. The steps S102 and S103 are not limited in sequence, and may be to send the advertisement video to the viewer in advance, or to send the advertisement video to the viewer after sending the prompt message, which is not limited herein. Step S101 and step S103 also have no sequential limitation, and may be to send the advertisement video to the viewer before the server receives the live video stream, or to send the advertisement video to the viewer during the process of receiving the live video stream by the server, which is not limited herein.
Step S101, in the process of receiving a live video stream sent by a main broadcasting end through pull streaming and forwarding the live video stream to a spectator end, detecting a starting frame and an ending frame of a key content video of the live video stream; the start frame represents that the key content video starts to be live broadcast, and the end frame represents that the key content video ends to be live broadcast.
After receiving a live video stream sent by a main broadcast end, a server carries out video decoding on the video stream according to the receiving sequence, and detects each frame of the decoded video stream according to the receiving time sequence so as to detect a starting frame and an ending frame of a key content video of the live video stream.
In this embodiment of the present application, there may be multiple methods for detecting a start frame and an end frame of a key content video of a live video stream, and two examples are listed below:
first, image matching.
Namely, presetting a starting characteristic image and an ending characteristic image of a key content video; and performing image matching on each frame of the live video stream, wherein the frame matched with the starting characteristic image is taken as a starting frame, and the frame matched with the ending characteristic image is taken as an ending frame.
In a specific implementation process, the types of the live video streams are different, and the corresponding preset starting characteristic image and the corresponding preset ending characteristic image are different. For example: the live video stream is a game live video stream, and the key content video is a video entering a game period. The image or character feature on the game entry screen is used as a start feature image (e.g., a progress bar image when the game is loaded, or a character such as "welcome entry"), and the image or character feature on the game exit screen is used as an end feature image (e.g., a character such as "exit", or a saved information pattern when the game exits).
Second, a signal added by the anchor.
Namely, when a main broadcast starts and ends a key content video according to a preset rule, a preset case is clicked or preset information is input so as to send an identification signal to a server, and the server starts and ends frames according to the time for receiving the identification signal and the time stamp of each frame in a video stream. A frame with the same time stamp as the time when the start identification signal is received may be taken as the start frame and a frame with the same time stamp as the time when the end identification signal is received may be taken as the end frame.
In a specific implementation process, the live video stream is a game live video stream, and the key content video is a video entering a game period; the live video stream is a singing live video stream, and the key content video is a video during singing; the live video stream is a spot check live video stream, and the key content video is a video during the lottery drawing, which is not limited herein and is not listed one by one.
Step S102, if the start frame is detected, sending start prompt information to a viewer; and if the ending frame is detected, sending an ending prompt message to a viewer.
In a specific implementation process, in order to facilitate a viewer to accurately confirm a start frame according to start prompt information and accurately confirm an end frame according to end prompt information, the start prompt information may carry a timestamp of the start frame, and the end prompt information may carry a timestamp of the end frame.
For example: the format of the start prompt message is: b-xx is xx; the format of the end prompt message is: and E-nn: nn. Wherein, B represents start prompt information, N represents end prompt information, xx is the time stamp of the start frame, and nn is the time stamp of the end frame.
Of course, the time stamp may not be carried, and the time of receiving the prompt information by the viewer is used as the time stamp information, which is not limited herein.
Step S103, sending an advertisement video to the audience so that the audience can identify a received non-key content video of the live broadcast video stream according to the start prompt message and the end prompt message, and playing the advertisement video in a preset time period for playing the non-key content video; and the non-key content video is the rest videos except the key content video in the live video stream.
In the implementation process, the advertisement video can be sent to the audience in advance or can be sent to the audience in the process of live broadcasting the live video stream.
The method for identifying the received non-key content video of the live video stream by the audience according to the start prompt information and the end prompt information comprises the following steps: and the video stream received in the middle period is the non-key content video from the moment when the audience receives the end prompt message to the moment when the audience receives the start prompt message. More precisely, the ending frame can be determined according to the timestamp information carried by the ending prompt information, the starting frame can be determined according to the timestamp information carried by the starting prompt information, and the video frames from the beginning to the beginning of the ending frame are non-key content videos according to the sequence of receiving the videos.
And after the audience identifies the received non-key content video of the live broadcast video stream, playing the advertisement video in a time period preset for playing the non-key content video. Specifically, the preset time period for playing the non-key content video is: and under the condition of not inserting the advertisement video, according to the sequence of receiving the live video stream by the audience, the time period that the non-key content video should be played.
In this embodiment of the application, there are various ways to play the advertisement video in a time period in which the non-key content video is preset to be played, and two examples are listed below:
first, instead of playing.
Namely, the advertisement video is used for replacing the non-key content video to be played in a preset time period for playing the non-key content video. That is, in the time period, the non-key content video is not played, and the advertisement video is switched to be played.
Second, composite playback.
The advertisement video and the non-key content video are synthesized, and the synthesized video is played in a preset time period for playing the non-key content video.
Specifically, the synthesizing of the advertisement video and the non-key content video may be that each of N frames of the advertisement video and each of N frames of the non-key content video are sequentially synthesized into N frames of synthesized video according to a time sequence, and each of the N frames of synthesized video includes an image of the non-key content video and an image of the advertisement video. Specifically, the image may be synthesized in a picture-in-picture manner, or may be synthesized in a jigsaw manner, which is not limited herein.
In a specific implementation process, the synthesizing of the advertisement video and the non-key content video may be that a frame of the advertisement video in the YUV format and a frame of the decoded non-key content video in the YUV format are subjected to image synthesis to form synthesized video data in the H264 format, and then, after audio-video mixing is performed on the synthesized video data and audio data in the ACC format of the non-key content video (or the synthesized video data and the audio data in the ACC format of the advertisement video), the synthesized video data and the audio data in the ACC format of the non-key content video are played in a preset time period for playing the non-key content video.
Specifically, a server detects a start frame and an end frame of a key content video of a live video stream in the process of receiving the live video stream sent by a main broadcasting end in a pull stream and forwarding the live video stream to a viewer end; and correspondingly sending start prompt information and end prompt information to a spectator end, so that the spectator end can identify the received non-key content video of the live broadcast video stream according to the start prompt information and the end prompt information, and play the advertisement video in a time period for playing the non-key content video in advance, thereby avoiding the problem that the advertisement is randomly inserted in the live broadcast key content video time period to interfere the watching of the live broadcast by a user, and effectively ensuring that the user knows the integrity and the continuity of the live broadcast content.
Based on the same inventive concept, the application also provides a method at the viewer side corresponding to the live broadcasting advertisement method in the first embodiment, which is detailed in the second embodiment.
Example two
The embodiment provides a live advertisement method, as shown in fig. 2, where the method is applied to a viewer side, and includes:
step S201, in the process of receiving a live video stream sent by a server, receiving start prompt information and end prompt information sent by the server, wherein the start prompt information and the end prompt information are respectively prompt information sent by the server after detecting a start frame and an end frame of a key content video of the live video; the starting frame represents that the key content video starts to be live broadcast, and the ending frame represents that the key content video ends to be live broadcast;
step S202, identifying a non-key content video of the received live broadcast video stream according to the start prompt message and the end prompt message, and playing the advertisement video in a preset time period for playing the non-key content video; and the non-key content video is the rest videos except the key content video in the live video stream.
It should be noted that the method provided in this embodiment is particularly suitable for real-time advertisement insertion in a live video process. Specifically, the main broadcasting end records a video, and sends a live video stream to the server in real time, and the server performs start frame and end frame detection in real time and sends the detected video stream to the audience end in real time. When the server detects the start frame or the end frame, the server immediately sends the start prompt information and the end prompt information to the audience in a short time so as to enable the audience to process and play the video.
The server may be a single server, a server group, a cloud server, or the like, and is not limited herein. The audience terminal and the anchor terminal may be a smart phone, a desktop computer, a tablet computer, or the like, which is not limited herein.
In this embodiment of the present application, the playing the advertisement video in a time period in which the non-key content video is preset to be played includes:
replacing the non-key content video with the advertisement video to play in a preset time period for playing the non-key content video; alternatively, the first and second electrodes may be,
and synthesizing the advertisement video and the non-key content video, and playing the synthesized video in a preset time period for playing the non-key content video.
Since the method described in the second embodiment of the present invention is a method implemented at the viewer end by the method described in the first embodiment of the present invention, based on the method described in the first embodiment of the present invention, those skilled in the art can understand the specific steps and variations of the method described in the present embodiment, and thus the detailed description thereof is omitted here.
Based on the same inventive concept, the application also provides a device corresponding to the live broadcast advertisement method in the first embodiment, which is detailed in the third embodiment.
