Abstract
A system and method for effectuating playlist seeking capability with respect to digital media content from a network node. A Real-Time Streaming Protocol (RTSP) Uniform Resource Locator (URL) or a Session Description Protocol (SDP) file including a set of appropriate play list-related control attributes is provided when a media user invokes a streaming session. Responsive to the RTSP URL or SDP file, an RTSP message is provided to the network node from the media user, the RTSP message including selected playlist-related control attributes in a URL query string associated with the identified playlist. In particular, the selected playlist-related control attributes include a clip index (that indexes into the playlist to identify a particular media clip) and an offset (that indicates a start time within the identified media clip) at which to commence streaming to enable more versatile seeking capability.
