Embodiment Construction

[0029] Because the extracted video information in the prior art is not comprehensive enough when extracting the mobile phone video index, it is difficult to fully reflect the outline of a shot by only extracting the first frame of the shot, so it is necessary to further extract the key frames of the shot. In addition, in addition to image information, the text in the video often also contains important information of the video, especially the concise and eye-catching text in the video. These texts are usually the summary of the theme of a video or the embodiment of the core content. Therefore, if the key texts of the video can be effectively located and extracted, and provided to the user, the core content of the video is often provided to the user. This undoubtedly plays a vital role in the user's video indexing, making the video indexing of mobile phones more accurate.

[0030] The basic physical unit of video is the shot. A shot is composed of several temporally continuous...

Abstract

The invention discloses a method and a device for extracting video indexes and a video downloading system. The method for extracting video indexes comprises the following steps: checking lenses of video files; analyzing the checked content of each lens; extracting a video key frame of each lens; positioning the edge of a particular text of the video files; recognizing the positioned text; extracting the recognized text as a key text; and using the key text and the video key frame of each lens as video indexes of the video files. The method for extracting video indexes can supply overall video index information for cell phone subscribers, effectively help the subscribers to select download videos and accurately position videos to be downloaded to avoid downloading unneeded videos, thereby the downloading of the videos more fits for the requirements of subscribers.

Description

technical field [0001] The invention relates to the technical field of video search, in particular to a method and device for extracting video indexes and a video downloading system. Background technique [0002] Generally speaking, compared with other information files, video files have larger capacity, more complex algorithms, and are not easy to analyze or index. However, with the increasing number of online videos and the explosion of social information, it is becoming increasingly important to effectively obtain video information and help users locate the content they are interested in among the massive videos. At present, video indexing technology is mainly used on personal computers, but it has not been widely used in mobile phone video. [0003] Compared with personal computers, mobile phones are limited by factors such as bandwidth and storage capacity, with slow transmission speed, small storage space, and poor computing and processing capabilities. Users are oft...
