Windows Media Player 11 SDK Rich Media Streaming
Complex Web pages contain many different components that are normally transferred separately. On a slow connection, such pages display one piece at a time and may take several minutes to display completely. This may prevent you from effectively synchronizing Web pages with your digital media. The solution to this problem is rich media streaming, which means adding your Web pages to your digital media stream so that they are delivered at the same time as the audio or video data.
Rich media streaming uses a simple frameset layout and behaves exactly like normal URL flipping. Just as in URL flipping, URL script commands embedded in digital media streams are used to display the content in the target frame. Instead of pointing to pages on the Web, however, the URL script commands are used by Windows Media Player 9 Series or later to access files in the Internet Explorer cache where the streamed HTML content is placed as it is received. Just as with normal URL flipping, you can write event handlers that respond to these URL script commands, or you can let the Windows Media Player control handle everything automatically.
Note Any HTML content delivered through rich media streaming is played back in the Internet security zone, and is subject to the user's browser security settings.
