Media Gateway Webcast is an enterprise-scale software platform that empowers users to easily produce compelling live or on-demand rich media presentations. Media Gateway Webcast delivers streaming video synchronized with PowerPoint slides, HTML Web pages, Flash presentations, text transcript, graphics, and other rich media content. These rich media presentations are fully interactive with live questioning and answering, interactive polling, quiz, and links to related documents. Media Gateway Webcast streamlines the entire webcast lifecycle workflow from webcast event scheduling, setup, announcement, user registration, to live webcast production control, and post-webcast report and analysis. During the live webcast, Media Gateway Webcast automatically records and indexes the entire presentation with synchronized interactive events to provide an on-demand presentation in searchable format right after the webcast. User can search on-demand presentations based on speech text, human faces, and database information automatically indexed with Pictron Media Gateway Suite software, or document content associated with PowerPoint slides, HTML Web pages, and PDF documents. Recorded webcast can also be distributed on CD, DVD, or designated Website.
