Problems solved by technology

[0005] However, when users use text or language to give feedback, they will be affected by factors such as personal habits and education level. The description of whether a certain segment meets their own preferences and interests may be inaccurate. Moreover, feedback information based on text or language is relatively subjective. and ambiguity, it is impossible to quantify the degree of user preference and interest, so that it is impossible to objectively determine which segments in the media data are more in line with user preference and interest
These two factors lead to the inaccurate identification of user preferences and interests by existing media data clipping methods

Embodiment Construction

[0069] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0070] One of the core concepts of the embodiments of the present application is that the physiological data can be used to objectively and real-time reflect the characteristics of the user's physiological response caused by the media data. The time axis acts as an intermediary to establish the corresponding relationship between media data and physiological data, and edit the characteristic media data according to the corresponding relationship, so that user preferences and interests can be identified accurately, comprehensively and efficiently.

[0071] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a method for editing media data of the present application, the media data ...

Abstract

The embodiment of the application provides a media data editing method. The method comprises the following steps: acquiring the physiological data of a plurality of users corresponding to time axes during acquisition of the same media data respectively; counting a time interval formed by corresponding time axes within a specified physiological data range; and editing corresponding media data according to the time interval for serving as feature media data. According to the application, essential segments which are consistent with user preference and interest in the media data can be identified accurately.

Description

technical field [0001] The present application relates to the technical field of media clipping, in particular to a media data clipping method and a media data clipping device. Background technique [0002] With the development of the media industry, users have a large amount of video, audio, software and other media data to choose from. [0003] On the one hand, users generally decide whether to purchase complete media data according to a promotional segment of the media data. On the other hand, in order to attract more users to buy, media suppliers will try their best to include the best clips that meet user preferences and interests when making promotional clips. In order to judge which segments in the media content meet the user's preferences and interests, users who have obtained the media data are usually asked to provide feedback information as a basis for judgment. [0004] The existing method is to manually collect the feedback information of the user's language o...
