Embodiment Construction
[0025] Such as figure 1 As shown, a search device for audio and video content, including:
[0026] A judging module, used to judge whether the current streaming media file includes audio files and video files;
[0027] An audio fingerprint extraction module, connected to the judgment module, for extracting audio fingerprints of multiple audio files;
[0028] The audio fingerprint word segmentation module is connected with the audio fingerprint extraction module, and is used to segment the extracted audio fingerprint;
[0029] An audio index generating module, connected to the audio fingerprint word segmentation module, is used to generate an audio fingerprint index according to word segmentation results;
[0030] A video fingerprint extraction module, connected with the judgment module, for extracting video fingerprints of multiple video files;
[0031] The video fingerprint word segmentation module is connected with the video fingerprint extraction module, and is used to c...

The invention discloses an audio and video searching device, which comprises a judgment module, an audio fingerprint extraction module, an audio fingerprint segmentation module, an audio index generation module, a video fingerprint extraction module, a video fingerprint segmentation module, a video index generation module and a search module, wherein the judgment module is used for judging if a current streaming media file comprises audio files and video files; the audio fingerprint extraction module is connected with the judgment module; the audio fingerprint segmentation module is connectedwith the audio fingerprint extraction module; the audio index generation module is connected with the audio fingerprint segmentation module; the video fingerprint extraction module is connected with the judgment module; the video fingerprint segmentation module is connected with the video fingerprint extraction module; and the video index generation module is connected with the video fingerprint segmentation module. In the device, a segmentation technique in a text search engine is used to perform segmentation processing of the audio fingerprint files first, then an index technique in the field of text search is used to perform the index processing of the audio fingerprints, and finally, after the index processing is completed, the search engine can search an audio segment input by a user. Thus, the method facilitates the search of the user and improves search efficiency.
Description
technical field [0001] The invention relates to a search method for audio and video contents. Background technique [0002] With the development of the Internet, search engines have become one of the essential tools for people to surf the Internet. Traditional search engines are all based on text search (Text Search), known as text search engines. The principle is: the search engine server collects a large number of webpages; and extracts the text in the webpage according to the existing rules and performs word segmentation (Word Segmentation). Common word segmentation methods, such as: word segmentation methods based on string matching, understanding-based Word segmentation method and statistical word segmentation method; the text search engine uses the text thesaurus as an index table for fast searching. When the user searches, the text is input to the server, and the server performs word segmentation on the text, performs a quick search according to the index table, and...
