The teleprompter is similar to scrolling news window type . For those of you who haven't hung around a TV studio, the teleprompter is what news broadcasters read from while announcing the news. Text appears line by line and lines that have already been read are forced off the top of the screen. This example adds a new element, time. The time begin tag tells each line what time it should appear on the screen.
Time is measured from the start of the presentation.
I think it's great that Real put in a lot of time developing this media type and not ignoring it in favor of graphics, video and audio. It makes a great low bandwidth addition to any multimedia presentation.
