To prepare for users to watch the presentation over a network, create two Web pages: an initial Web page and a main viewing Web page. Examples of these Web pages are in the SystemDrive\Program Files\Windows Media Components\Tools\Presenter folder. If you want to use these Web pages for a presentation, replace the image paths and server IP addresses in the scripting provided with the locations of your images and servers. For more information on using these pages, see Presenter sample pages.
The initial Web page contains a file-transfer control that is used to transfer the PowerPoint slides into the user's browser cache. This reduces the amount of time the user must wait to see the slides and enables a smoother-looking slide presentation.
The main viewing page contains a frame for watching the video stream, a frame for viewing the presentation slides, and a file-transfer control. If the user does not receive all the images from the initial page, the control transfers the remaining images to the browser cache. If the main Web page receives a script command that calls for an image that is not in the computer's cache, the browser downloads the image from the HTTP server that contains copies of the presentation images.
Before the presentation, give users the URL for the initial Web page, and encourage them to go to the URL a few minutes before the presentation starts.
When users open the initial Web page, the file-transfer channel opens and begins transferring the presentation images to the computer's cache. When you start the presentation, the initial Web page automatically flips to the main Web page. The code that prompts this flip is embedded in the initial Web page. You enter the time when the Web page must flip and the URL of the main Web page.
