Problems solved by technology

Since only the number of times users order is considered in the evaluation of video unpopularity, the existing evaluation results of video unpopularity cannot objectively reflect the real unpopularity of the video, which will cause edge nodes to delete aged unpopular videos and recycle storage resources. Not only will the storage resources of the edge nodes not be effectively allocated, but it will also increase the pressure on the central nodes

Embodiment 1

[0048] This embodiment provides an unpopular video evaluation method, such as figure 1 shown, including:

[0049] Step S10: Record the number of valid views of the pre-cooling video within the set period. Wherein, the pre-cooling video is a video whose number of times of ordering is less than the first set threshold within the set period. Effective viewing refers to the viewing behavior of continuously watching the pre-cooling video for a duration longer than the second set threshold.

[0050] Wherein, the first set threshold and the second set threshold can be set arbitrarily according to specific situations.

[0051] Step S11: Calculate the viewing popularity value of the pre-cooling video according to the effective viewing times of the pre-cooling video.

[0052] In this step, the calculation formula for the viewing popularity value of the pre-cooling video is:

[0053]

[0054] Among them, μ is the viewing popularity value of the pre-cooling video; i is the serial num...

Embodiment 2

[0058] This embodiment provides an unpopular video evaluation method, such as figure 2 shown, including:

[0059] Step S10: Record the number of valid views of the pre-cooling video within the set period. Wherein, the pre-cooling video is a video whose number of times of ordering is less than the first set threshold within the set period. Effective viewing refers to the viewing behavior of continuously watching the pre-cooling video for a duration longer than the second set threshold.

[0060] Wherein, the first set threshold and the second set threshold can be set arbitrarily according to specific situations.

[0061] Step S11: Calculate the viewing popularity value of the pre-cooling video according to the effective viewing times of the pre-cooling video.

[0062] In this step, the calculation formula for the viewing popularity value of the pre-cooling video is:

[0063]

[0064] Among them, μ is the viewing popularity value of the pre-cooling video; i is the serial ...

Embodiment 3

[0086] Based on the unpopular video evaluation method provided in Embodiment 2, this embodiment provides an unpopular 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 pre-cooling video within a set period. The pre-cooling video is a video whose number of requests is less than the first set threshold within the set period. Effective viewing refers to the viewing behavior of continuously watching the pre-cooling video for a duration longer than the second set threshold. The calculation module 2 is used to calculate the viewing popularity value of the pre-cooling video according to the effective viewing times of the pre-cooling video. The evaluation module 3 is used to evaluate whether the pre-cooling video is an unpopular video according to the effective number of views and viewing popularity of the pre-cooling video.

[0087] By setting the calculation module 2 and the evaluation mo...

Abstract

The invention provides an unpopular video evaluation method and system. The unpopular video evaluation method comprises: recording the effective watching number of a pre-cooled video within a set period, the pre-cooled video being a video of which the on-demand number is smaller than a first set threshold within a set period, and the effective watching being a watching behavior that the duration of continuously watching the pre-cooled video is greater than a second set threshold; calculating a watching popularity value of the pre-cooled video according to the effective watching number of the pre-cooled video; and evaluating whether the pre-cooled video is an unpopular video according to the effective watching number and the watching popularity value of the pre-cooled video. The unpopular video evaluation method comprehensively considers the on-demand number, effective watching number and watching popularity value of a video, so that the unpopular video evaluation method can reflect thetrue degree of unpopularity of the video more objectively, the evaluation result of the unpopular video is more objective and accurate, the storage space within a node is efficiently deployed and utilized, and the pressure of the central node of a video content delivery network is reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method and system for evaluating unpopular videos. Background technique [0002] In order to ensure the smoothness of users watching videos, the content delivery network (Content Delivery Network, CDN) will distribute hot videos (that is, watching popular videos, such as popular movies) to edge nodes closer to users in time, so that edge nodes Provide users with on-demand services. However, as time goes by, the viewing popularity of video content will decrease. At this time, unpopular videos (that is, videos with low viewing popularity) need to be deleted and aged to reclaim node storage resources. In order to ensure that the truly unpopular video content is deleted and aged, the evaluation of the unpopularity of the video is very important. [0003] At present, the degree of unpopularity of videos is mainly evaluated based on the number of times users ord...
