Abstract

The embodiment of the invention provides a video playing evaluation method and device. The method comprises the steps of obtaining a grade value of a definition grade factor of a played video and a numerical value of a target playing factor; Determining a target evaluation function corresponding to the obtained grade value from the corresponding relationship between each grade value and the evaluation function; And obtaining an evaluation result of the played video based on the target evaluation function and the numerical value of the target playing factor. According to the technical scheme, the definition grade factor is added in the evaluation process to serve as the non-service-quality feature, the service quality feature of the playing interaction factor and / or the playing experience factor is further included, and evaluation is more comprehensive compared with evaluation in the prior art based on the non-service-quality feature and the service quality feature. Wherein the definition level factor is related to the playing interaction factor and the playing experience factor, and the playing interaction factor is not related to the playing experience factor, so that the increasing number of the cross features is controlled, and the increasing degree of the evaluation complexity is further controlled.

Description

technical field

[0001] The present invention relates to the field of multimedia technology, in particular to a method and device for video playback evaluation. Background technique

[0002] Browsing videos on video sites has become a daily routine, and many video sites provide users with more choices. For each video network, how to attract and retain users has become a key issue. Among them, user experience is an important factor for user retention. Only by improving user experience can there be a chance to retain more users.

[0003] In order to improve the user experience, it is necessary to understand the viewing experience of the user in the process of watching the video, that is, QoE (QualityOf Experience, Quality of Experience), and then make targeted improvements. At present, there are mainly two ways to evaluate the user experience. The first way is to display the playback evaluation for the user after each video is played, and the user can fill it in according to ...

Embodiment Construction

[0072] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0073] Compared with the prior art, in order to achieve a more comprehensive evaluation and control the increase in the complexity of the evaluation, an embodiment of the present invention provides a video playback evaluation method and device, wherein the video playback evaluation method includes:

[0074] Determine the level value of the sharpness level factor of the played video and the value of the target playback factor; wherein, the target playback factor includes the playback interaction factor and / or the playback experience factor, there is no correlation between the playback interaction factor and the playback experience factor, clear The degree rating factor is correlated with the target playback factor;

[0075] From the corresponding relationship between each level value of the sharpness lev...
