Abstract

A system and methods are provided for server side conversion for PowerPoint slides to video to retain effects like animation, transitions and multimedia audio/video through video analytics, during an online conference session. This solution does not require that a client have Microsoft Office® installed on the client machine that is sharing a file during the meeting. This in turn allows many endpoints to participate in live presentation sessions. This solution works well for any endpoints that have the capability to view video.

ABSTRACT

    A system and methods are provided for server side conversion for PowerPoint slides to video to retain effects like animation, transitions and multimedia audio/video through video analytics, during an online conference session. This solution does not require that a client have Microsoft Office® installed on the client machine that is sharing a file during the meeting. This in turn allows many endpoints to participate in live presentation sessions. This solution works well for any endpoints that have the capability to view video.

DETAILED DESCRIPTION

     A video endpoint (e.g., Telepresence) or a browser-based thin client can view all features of PowerPoint® (animations, transitions and multimedia audio/video) during an online presentation session.

    In an online meeting, participants join the meeting from different endpoints (e.g., Telepresence endpoints, different browsers (Firefox®, Chrome®, Safari®, Internet Explorer®, etc.), desktops and laptops (Apple OS and Windows®), IOS® and Android® devices). A solution is presented herein so that regardless of the particular endpoint a presenter uses to join the meeting, as long as it has the capability to view video, it can participate in viewing and sharing PowerPoint files during the presentation sessions and retain full control on the animations, transitions and multimedia effects in PowerPoint files.

    The solution involves converting PowerPoint slides to video at the server side and then run the video through video analytics on individual slide video to retain animation, transitions and multimedia audio/video effects. Importantly, PowerPoint's sophisticated features are retained through video analytics.

Generally, the mechanism involves the following steps.

The PowerPoint file that the presenter uploads is converted to video at the server.

Each slide in a PowerPoint file is converted to video.

    To separate out the animations and transitions control in the PowerPoint file, video analytics is used to decompose the video file to multiple video files for each animation/transition control.

    Figure 1 illustrates a process flow by which the PowerPoint file is uploaded to the server.

    The Client is the end user interface to host rooms or meetings. It provides "File Sharing" option in a meeting, and supports a Video Player to view the file content shared during the meeting.

    The Web Server is one of the first points of contact for clients for meeting room related activity. It leverages existing interfaces for upload/download of a file shared in the meeting/room.

    The Conversion Server converts a document to video (mp4) or image (png) files and stores the files in the File Storage. This m...
