Step S08: judge to preheat whether video within continuous three setting periods is not evaluated as temperature video.
In the step, the appraisal procedure of temperature video is above-mentioned steps S120~step S122.
If so, thening follow the steps S09: will preheating video switch to ordinary video, and rejudge ordinary video whether be
Preheat video.
In the step, by judging whether video-on-demand times are greater than the first given threshold within the setting period, so that it is determined that general
Whether intervisibility frequency is preheating video.
Step S08 and step S09 are executed before step S10.It, can be when undergoing one section by step S08~step S09
Between after (such as three setting periods), preheating video evaluations are re-started (i.e. again to the preheating video for not being assessed as temperature video
Whether secondary confirmation video is preheating video), since the viewing temperature of video can change over time, so above-mentioned steps can make to preheat
The assessment result of video is more objective and accurate, to further make the assessment result of temperature video also more objective and quasi-
Really.
In the present embodiment, temperature video evaluations method further include: step S13: being marked temperature video, and by temperature
Video is sent to Video Distribution Network.
In the step, Video Distribution Network can give temperature video distribution from the closer fringe node of user, so as to edge
Node provides the order program service of the temperature video for user.
Examples 1 to 2 the utility model has the advantages that temperature video evaluations method provided by Examples 1 to 2, by according to preheating
Whether effective watched time of video and viewing hot value are that temperature video is assessed to preheating video, compared to it is existing only
According to the method that the video-on-demand times of video assess temperature video, the temperature video evaluations method in the present invention has comprehensively considered video
Video-on-demand times, effective watched time and viewing hot value, to keep the temperature video evaluations method more objectively anti-
The true temperature of video is reflected, and then keeps the assessment result of temperature video more objective and accurate, by the temperature video distribution to view
The fringe node of frequency content distributing network (CDN) will not only waste the storage resource of fringe node, while also reduce content point
The pressure of Network Central Node is sent out, to ensure that user watches the fluency of video.
