Problems solved by technology

Since only the number of user requests is considered in the evaluation of video popularity, the existing video popularity evaluation results cannot objectively reflect the real popularity of the video, which will lead to the distribution of non-hot videos to edge nodes, which not only wastes the storage resources of edge nodes , and it will increase the pressure on the central node, and the fluency of users watching videos will not be guaranteed

Embodiment 1

[0042] This embodiment provides a hot video evaluation method, such as figure 1 shown, including:

[0043] Step S10: Record the number of effective viewing times of the warm-up video within the set period. Wherein, the warm-up video is a video whose number of times of ordering is greater than the first set threshold within a set period. Effective viewing is a viewing behavior in which the duration of continuous viewing of the warm-up video is longer than the second set threshold.

[0044] Wherein, the first set threshold and the second set threshold can be set arbitrarily according to specific situations.

[0045] Step S11: Calculate the viewing popularity value of the pre-heating video according to the effective viewing times of the pre-heating video.

[0046] In this step, the calculation formula for the viewing popularity value of the preheating video is:

[0047]

[0048] Among them, μ is the viewing popularity value of the warm-up video; i is the serial number of t...

Embodiment 2

[0052] This embodiment provides a hot video evaluation method, such as figure 2 shown, including:

[0053]Step S10: Record the number of effective viewing times of the warm-up video within the set period. Wherein, the warm-up video is a video whose number of times of ordering is greater than the first set threshold within a set period. Effective viewing is a viewing behavior in which the duration of continuous viewing of the warm-up video is longer than the second set threshold.

[0054] The first set threshold and the second set threshold can be set arbitrarily according to specific conditions.

[0055] Step S11: Calculate the viewing popularity value of the pre-heating video according to the effective viewing times of the pre-heating video.

[0056] In this step, the calculation formula for the viewing popularity value of the preheating video is:

[0057]

[0058] Among them, μ is the viewing popularity value of the warm-up video; i is the serial number of the set pe...

Embodiment 3

[0075] Based on the popular video evaluation method provided in Embodiment 2, this embodiment provides a popular video evaluation system, such as image 3 As shown, it includes: a recording module 1, which is used to record the number of valid views of the warm-up video within a set period. The warm-up video is a video whose number of requests is greater than the first set threshold within the set period. Effective viewing is a viewing behavior in which the duration of continuous viewing of the warm-up video is longer than the second set threshold. The calculation module 2 is used to calculate the viewing popularity value of the pre-heating video according to the effective viewing times of the pre-heating video. The evaluation module 3 is used to evaluate whether the pre-heating video is a hot video according to the number of valid views of the pre-heating video and the viewing popularity value.

[0076] By setting the calculation module 2 and the evaluation module 3, the ho...

Abstract

The invention provides a hot video evaluation method and system. The hot video evaluation method comprises the steps of recording effective watching number of times of a preheating video in a set period, wherein the preheating video is a video, the video on demand number of times of which is greater than a first set threshold in the set period, and effective watching refers to a watching behaviorcharacterized in that a duration of continuously watching the preheating video is greater than a second preset threshold; calculating a watching heat value of the preheating video according to the effective watching number of times of the preheating video; and evaluating whether the preheating video is a hot video according to the effective watching number of times and the watching heat value of the preheating video. The hot video evaluation method considers the video on demand number of times, effective watching number of times and a watching heat value of a video, so that the hot video evaluation method can reflect the actual heat level of the video more objectively, and the evaluation result of the hot video is more objective and accurate. The hot video is allocated to an edge node, notwasting storage resource of the edge node but relieving pressure of a center node of a content delivery network.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method and system for evaluating popularity videos. Background technique [0002] In order to ensure the fluency of users watching videos, the content delivery network (Content Delivery Network, CDN) will distribute popular videos (such as popular movies) to edge nodes closer to users in a timely manner, so that edge nodes can provide users with on-demand services. In order to distribute the real hot video to the edge nodes, the hot evaluation of the video is very important. [0003] At present, the popularity of a video is mainly evaluated based on the number of times users order it. For example, a threshold for the number of times a video is ordered is set in advance. In the set period, when the number of times the user orders exceeds the threshold, the video is determined to be popular. video. Since only the number of user requests is considered in the ...
