Abstract
Web-based viewing of short audio or video clips presents a dilemma: either the clip is streamed
at low quality, or a high quality version is downloaded, forcing the user to wait. It is difficult to
convince users to wait for clips that they may discover to be uninteresting to them. Progressive
Layered Media (PLM) solves this dilemma by streaming layered media. The first playback uses
the base layer, which is cached as it is played back. Each subsequent playback streams the next
layer, caches it, and plays it back in conjunction with the already cached layers. Thus, each
playback has improved quality. PLM avoids the delays of downloading, allowing the user to
preview a low quality of the clip (the base layer). If the clip is interesting, the high quality
version can be obtained by repeated playback, in less time than a download would take, as the
base layer has already been played.
