摘要： The present invention provides a system and a method making an archived conference or presentation searchable after being stored in the archive server. According to the invention, one or more media streams coded according to H.323 or SIP are transmitted to a conversion engine for converting multimedia content into a standard streaming format, which may be a cluster of files, each representing a certain medium (audio, video, data) and/or a structure file that synchronizes and associates the different media together. When the conversion is carried out, the structure file is copied and forwarded to a post-processing server. The post-processing server includes i.a. a speech recognition engine generating a text file of alphanumeric characters representing all recognized words in the audio file. The text file is then entered into the cluster of files associating each identified word to a timing tag in the structure file. After this post-processing, finding key words and associated points of time in the media stream could easily be executed by a conventional search engine.
摘要翻译：本发明提供一种在归档服务器中存储之后，使归档会议或表示可搜索的系统和方法。根据本发明，根据H.323或SIP编码的一个或多个媒体流被发送到转换引擎，用于将多媒体内容转换成标准流格式，其可以是一组文件，每个文件集合表示某一媒体（音频，视频，数据）和/或将不同媒体同步并关联在一起的结构文件。执行转换时，将结构文件复制并转发到后处理服务器。后处理服务器包括i.a. 语音识别引擎，生成表示音频文件中的所有识别的单词的字母数字字符的文本文件。然后将文本文件输入到将每个识别的单词与结构文件中的定时标签相关联的文件集合中。在这种后处理之后，在传统的搜索引擎中可以容易地执行在媒体流中查找关键词和相关时间点。
