1. SPOT Slide Presentation Over Telephony A CS 790 Project by Jason Howes

2. What is SPOT?  An ITX application suite for creating and playing slide presentations with synchronized streaming audio.  Three applications: xSPOT Wizard xSPOT Client xSPOT Server

3. SPOT Features  Makes extensive use of the ITX telephony package.  Supports both local and remote presentation viewing.  Slide presentations are created from PowerPoint presentations.  Allows a user to move back and forth within the presentation via an interface similar to that of a CD player.

4. SPOT Wizard  Used to create new slide presentations from an existing PowerPoint presentation.  A CD player interface is used to navigate through the PowerPoint presentation.  Outputs two files: xRAD File - Raw Audio Data File xPAM File - Presentation Audio Mapping File

5. SPOT Client  Used to view the slide presentation.  The client can view local presentations created by a SPOT Wizard or remote presentations served by a SPOT server.  A CD player interface is used to navigate through the SPOT presentation.

6. SPOT Server  Serves a SPOT presentation to a SPOT client.  Can support multiple clients simultaneously.  Since the SPOT suite is based on the ITX telephony package, audio can be streamed to the SPOT client machine or to a telephone.

7. How Does It Work?  A user surfs the Web to a SPOT Presentation Archive and then downloads a SPOT file, which contains information on all of the SPOT servers that can serve the particular SPOT presentation. The user then starts a SPOT client.  The SPOT client uses the SPOT file to present a list of SPOT servers to the user. The user then connects to a SPOT server, which then serves a slide presentation with synchronized audio streamed over telephony.
