  • Patent number: 8560641
    Abstract: The present invention relates to video conferencing and multimedia messaging, and takes advantage of the capabilities of the communication system to which the audio participants are connected, in order to increase the performance of all the participants in a mixed conference. In a preferred embodiment, the audio participants are provided with a MMS device, and a MMS Engine captures periodically, or at certain events, video conference data attached to MMS messages and addressed to the MMS device. In the opposite direction, the MMS device provides multimedia data to the conventional video conference participants by attaching the multimedia data to MMS messages, which are sent to the IP-addressable MMS Engine. The MMS Engine separates the multimedia data and converts it to a format compatible with the video conference. The converted multimedia data is then provided to video conference participants, and treated like any other multimedia stream included in the video conference.

  • Patent number: 8103507
    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.
