The implementation details of the live review scheduling method according to this embodiment are specifically described below, and the following description is only provided for facilitating understanding, and is not necessary for implementing this solution.
A flow diagram of the live review scheduling method in this embodiment is shown in fig. 1:
step 101: and counting the downloading times of the video slices of each live view.
Specifically, in the prior art, a plurality of cameras are usually used in a live broadcast site to simultaneously acquire video signals in a live broadcast environment, each camera corresponds to a live broadcast view, and a live broadcast video stream at each live broadcast view is uploaded through the internet and directly injected into a CDN platform (Content Delivery Network). The CDN platform receives live video streams from different cameras and different protocols, translates the live video streams of all live view angles, and stores the live video streams in the same video format in the CDN platform. For example, the hls protocol is currently mainstream. The video camera sends the live video stream to the CDN platform through different transmission protocols, and the CDN platform packages the received live video stream into ts video slices in a unified mode and stores the ts video slices in the CDN platform. When a user in a certain region accesses a certain live broadcast view angle of the live broadcast, a CDN node in the region receives an access request of the user, and a CDN platform sends a live broadcast video stream of the live broadcast view angle to the CDN node in the region, so that the CDN node in the region provides the live broadcast video stream of the live broadcast view angle for the user or other users in the region, and CDN acceleration is realized.
The CDN node in each domain records historical access information of all users accessing the CDN node, for example: there are how many users viewed live slices from a certain viewing angle at a certain historical moment. In this embodiment, the historical access information is the download times of the video slices, and the greater the download times of a certain video slice, the greater the number of people watching the video slice, and the higher the popularity of the video slice. For example, in a live broadcast ball game of beijing national security to shanghai scholaria, the number of times of downloading live broadcast video slices at the beijing view angle by the CDN node in the beijing area is higher, and the number of times of downloading live broadcast video slices at the shanghai view angle by the CDN node in the shanghai area is higher.
Step 102: a review request of the user terminal is received, and a review period is determined in response to the review request.
In this embodiment, determining a review time period in response to the review request specifically includes: determining a review time point and a current live time point in response to the review request; and determining a review time period according to the review time point and the current live broadcast time point.
Specifically, in this embodiment, when receiving a review request from a user terminal, a CDN node in the area of the user terminal determines a review time point and a current live time point in response to the review request, thereby determining a time period for the user to review (the review time period is current live time point — review time point).
Step 103: video slices for respective live views within a review time period are determined.
Specifically, after the review time period of the user terminal is determined, the video slices of the live view angles of the live video in the review time period are determined, so that the download times of the video slices of each live view angle in the review time period can be acquired.
Step 104: and sequencing the video slices of each live view in the review time period according to the downloading times.
Step 105: and obtaining a plurality of video slices according to the sequence from the video slice with the highest downloading frequency, wherein the accumulated time of the video slices is the same as the review time.
Step 106: and integrating the plurality of video slices to obtain a video slice to be recommended, and recommending the video slice to be recommended to the user terminal.
Specifically, for the above steps 103 to 104, the video slices at each live view in the review time period are sorted according to the downloading times, and a plurality of video slices are obtained from the video slice with the highest downloading time according to the sorting, so that the accumulated time of the plurality of video slices is the same as the review time, that is, the downloading times, that is, the heat of each video slice of the obtained plurality of video slices is higher than that of other video slices. Therefore, the video slices with higher heat are integrated to obtain the video slices to be recommended, and the video slices to be recommended are recommended to the user terminal. The video slices of the live videos are combined and recommended according to the downloading times, so that the content seen by the user with the user terminal is more diversified and richer, and the user experience is improved.
For example: in a live broadcast ball game of Beijing national security to Shanghai Shenhua, a Beijing user requests to watch a video review before 1 minute again, and if one ts slice is 10s, the CDN node of the Beijing obtains the downloading times of the video slices of each live broadcast view angle within 1 minute, reorganizes the first 6 video slices with more downloading times to obtain a video slice to be recommended and pushes the video slice to the user terminal. The 6 video slices are likely not from the same live view, and the live view of the video slice viewed by the user holding the user terminal is likely to be different from the live view viewed by the user prior to review.
The user sees 6 ts slices, ordered by the user's play hotness in this region. That is, the review content viewed by the user may not be consistent with the previously viewed live seat.
In this embodiment, integrating a plurality of video slices to obtain a video slice to be recommended specifically includes: determining a starting time point of each of a plurality of video slices; sequencing the video slices according to the time sequence according to the starting time point of each video slice; and taking the sequenced video slices as video slices to be recommended.
Specifically, in the embodiment, when a plurality of video slices are integrated, the plurality of video slices are sequenced according to the time point of each video slice and the plurality of video slices sequenced according to the time sequence are used as video slices to be recommended, so that the video slices watched by the user have a chronological order, and the user can watch the video slices conveniently.
In this embodiment, recommending a video slice to be recommended to a user terminal specifically includes: and generating a download address of the video slice to be recommended, and sending the download address to the user terminal so that the user terminal can download the video slice to be recommended according to the download address.
Specifically, when the CDN node pushes a video slice to be recommended to the user terminal, a download address of the recommended video slice is generated first, where the download address is a plurality of sub-download address groups, and one sub-download address corresponds to one video slice. And after receiving the sub-download address group, the user terminal sequentially downloads and plays the video slices according to the sequence of each sub-download address in the sub-download address group.
Compared with the prior art, the live-broadcast review scheduling method provided by the embodiment of the invention has the advantages that the video slices of the live-broadcast videos are combined to obtain the video slices to be recommended according to the access information of the user by counting the historical access information of the video slices of the live-broadcast views, and the video slices to be recommended are recommended to the user terminal, so that the video slices of the live-broadcast videos are combined and recommended according to the historical access information, the content seen by the user holding the user terminal is more diversified and richer, and the user experience is improved.
The second embodiment of the invention relates to a live-broadcast review scheduling method. The second embodiment is substantially the same as the first embodiment, and the main difference is that in this embodiment, by acquiring a video slice of a live view angle with the highest download frequency in all live view angles within each video slice time, a time-continuous video slice to be recommended with higher heat is obtained, so that a user holding the user terminal can view the video slice of the live view angle with the highest heat within each video slice time, and user experience is further improved.
A flow diagram of the live review scheduling method in this embodiment is shown in fig. 2, and specifically includes:
step 201: and counting historical access information of the video slices of each live view.
Step 202: a review request of the user terminal is received, and a review period is determined in response to the review request.
Step 203: video slices for respective live views within a review time period are determined.
The steps 201 to 203 are substantially the same as the steps 101 to 103 in the first embodiment, and are not described again.
Step 204: a plurality of video slices for which a broadcast view is within a review period is determined.
