Abstract

The object of the present invention is to provide a method and device for acquiring characteristic information of multimedia data. Wherein, the multimedia information acquisition device acquires the identification information of the multimedia data; generates a playback request of the multimedia data according to the identification information; sends the playback request to the network device where the multimedia data is located; receives the playback request from the network device In response to the multimedia play response information fed back by the play request; according to the multimedia play response information, the feature information of the multimedia data is acquired. Compared with the prior art, the present invention provides a general method for obtaining characteristic information of multimedia data, so that the characteristic information of multimedia data can still be obtained when the characteristic information is not included in the multimedia data webpage, thereby improving Search coverage of multimedia data.

Description

technical field [0001] The invention relates to Internet technology, in particular to a technology for acquiring characteristic information of multimedia data. Background technique [0002] The web crawling tools of traditional search engines, such as "web spider (spider)", "web crawler (crawler)" or "robot (robot)", etc., the methods of grabbing video feature information such as video thumbnails and video duration are mainly By analyzing the video webpage provided by the video website, and extracting the video feature information from it, the disadvantage of this method is that if the video webpage does not contain the video feature information, the web crawler will not be able to obtain the video feature information, and then Affect the search coverage of search engines on video web pages. [0003] Therefore, how to effectively obtain feature information of multimedia data has become an urgent problem to be solved. Contents of the invention [0004] The object of the p...
