    Abstract: 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.
