The ActiveMovie Streaming Format is an open and extensible data-independent format for archiving, annotating, indexing and transmitting synchronized multimedia content. More specifically, ASF allows multiple data objects (for example, audio objects, video objects, still images, events, URLs, hypertext markup language (HTML) pages, and programs) to be combined and stored into a single synchronized multimedia stream. It provides an encapsulation that allows existing popular media types and formats such as MPEG, AVI, .WAV and Apple® QuickTime® to be synchronized and stored efficiently on a variety of servers.
