DirectShow RTP Support for Adaptivity in Networked Multimedia Applications

Execution of an interactive collaboration application or a distributed game involves many individual multimedia applications that concurrently generate and/or play back several audio and video streams. As the resource requirements of individual streams change and as streams/applications are started or later terminated, the amount of available resources may change dynamically. Networked MultiMedia (NetMM) applications must be willing to adapt to these changes by taking advantage of the fact that they can deliver varying levels of services that are acceptable to users. This paper addresses the problem of adding network and host adaptive capability to the component-based DirectShow RTP.
