A video playing evaluation method and device

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 ...

Problems solved by technology

[0004] However, the inventor found in the process of implementing the present invention that the prior art has at least the following problems: For the second method, only the impact of service quality features is reflected in the evaluation process, while the impact of non-service quality features is lacking. make the assessment less comprehensive

However, if non-service quality features are added, cross features need to be added in the evaluation process due to the correlation between each feature, and the increase of cross features will increase the complexity of evaluation

For example, if the quality of service features include A and B, then add non-quality of service feature C, and there is correlation among A, B, and C, then in addition to evaluating A, B, and C, it is also necessary to evaluate the cross feature A* B, B*C and C*A are evaluated, which greatly increases the complexity of the evaluation
