Abstract
A buffering protocol and a streaming media player which utilizes the buffering protocol designed for minimizing the occurrences of pauses during the presentation due to network congestion and for scheduling pauses at appropriate times in the presentation. The data comprises coded content information comprising a time synchronous media, together with various other sources, synchronized to appear at predetermined time points in the media presentation. The presentation is delivered in streaming fashion, so that the end user does not have to wait for the entirety of the data to be downloaded before starting the presentation. The invention does not require that media data and events data be multiplexed into a single streaming file and it does not require that the file provided to the media player be customized for prefetching of content.
