Embodiment Construction

[0149] As shown in Figures 1 and 2, the content-based video search system consists of video analysis server clusters such as video content analysis, voice analysis, subtitle analysis, and fusion analysis, as well as metadata retrieval, distributed voice retrieval, subtitle retrieval, video retrieval, and video search It consists of video retrieval server clusters such as scheduling servers.

[0150] As shown in Figure 3, the video content analysis subsystem includes a video stream acquisition module, a video content analysis module, a video content analysis result review module, an input interface, an output interface, a task scheduling module, and a user interface.

[0151] The system receives video analysis commands through the input interface, and there are two receiving methods: receiving video analysis commands from the video fusion analysis server through the network TCP connection and obtaining the user's video analysis commands locally. The video fusion analysis server...

Abstract

This invention provides a video search system based on content including an analysis server of video, phone, caption and man-face, a merging analysis server, a video search server cluster and a search dispatch server, in which, the analysis server can analyze and pick up video content information from the video and generate related spelling pattern information by analyzing audio signals to set up video index by analyzing and describing video content word information, the merging analyzing system merges data got from video analysis, phone analysis and caption analysis to generate index information, the video index server cluster stores the video content and the structure by the analysis system, the search system can enquires various information and feed back the result to the search dispatch server, which receives the research request of the customer end to analyze and transmit the request to the research cluster and generate ordered enquiry result.

Description

technical field [0001] The invention relates to the fields of content-based video, voice, subtitle, image analysis and retrieval. Including structural analysis of video content, key frame image analysis, subtitle extraction and recognition, organization and storage of speech feature data, and technologies in the fields of indexing, retrieval and distributed retrieval of information such as video, image, voice and subtitles. Background technique [0002] Content-based video retrieval refers to the retrieval of video programs based on the characteristics of the video program content. At present, there are already some retrieval systems for video programs in the industry. These systems manually annotate the existing video files, such as typing in the name of the video program, content introduction, etc. The retrieval of these videos is actually based on artificial text. The core technology for matching annotations is still the traditional text-based retrieval technology. Howe...
