Embodiment Construction

[0071] 1. Fully automatic video cataloging system architecture, such as figure 1 shown, including:

[0072] 1. Media acquisition module

[0073] The subsystem collects the video stream data into the computer memory through the video capture board and the corresponding driver of the board, and transmits it to the media analysis module.

[0074] 2. Media analysis module

[0075] For the collected video stream data, according to the set configuration options, the module selects the corresponding processing algorithm and its control parameters, conducts intelligent analysis and extracts key frames or shot segmentation frames, and extracts the extracted key frames or shot segmentation frames And the corresponding time code information is displayed on the storyboard area of ​​the user interface for further editing and processing by the user.

[0076] 3. Media metadata creation, editing and management module

[0077] Media metadata management includes creation and modification of...

Abstract

The invention discloses a full-automatic video cataloging system and a full-automatic video cataloging method. The system is mainly used for automatically building a metadatabase of massive non-structured media materials, simultaneously supporting manual modification, adding and perfection of metadata on that basis, and finally realizing the aim of effective management on massive media assets through the perfected media metadatabase. The system comprises a full-automatic video cataloging system function and system architecture, a media material video key frame robustness automatic extraction algorithm and a media material shot segmentation key robustness automatic extraction algorithm. The software realized based on the method provided by the invention can realize the real-time processing effect on the existing mainstream computers. The video key frame and shot segmentation robustness extraction algorithm provided by the invention has good anti-interference effect on the influence of camera flash and special effects including wiping off, fading in fading out and dissolving which frequently appear in video, so that excess omissions and false drop caused by the interference can be avoided.

Description

technical field [0001] The invention relates to multimedia technology, in particular to the establishment and effective management of metadata of massive media materials. Background technique [0002] Today's society is a society with rapid information development, and a large amount of various types of information are generated every day. Especially in the film and television industry, a large amount of multimedia materials are produced and accumulated. However, multimedia data itself is a kind of unstructured data, how to effectively manage these media data is an urgent problem faced by the media industry. [0003] Media Asset Management (Median Asset Management, MAM) is an end-to-end overall solution for the comprehensive management of various types of media and content (such as video / audio materials, text files, graphics, etc.) The entire process of collection, cataloging, management, transmission and code conversion. It fully meets the functional requirements of medi...
