Abstract

A method and apparatus for adapting media is provided. The method includes receiving a request for a first media stream and a second media stream at different media times. The method further includes processing a source media stream to produce a first portion media stream and a second portion media stream using a media processing element. A method for processing media comprises creating a first media processing element and a second media processing element. The method further includes processing a first media stream using the first media processing element to produce assistance information. Further, the method includes processing a second media stream using the second media processing element wherein the second media processing element utilizes the assistance information.

Claims
