ASF is the core of Microsoft’s Windows Media, a data format containing audio, video, images, and control command scripts. This term is currently used interchangeably with WMA and WMV.

The use of ASF files can realize on-demand functions, live broadcast functions, and remote education, with local or network playback, expandable media types, and other advantages. The data rate of ASF streaming files can vary from 28.8Kbps to 3Mbps. Users can choose a suitable rate according to their application environment and network conditions to achieve VOD on demand and live broadcast. Many media players support ASF file, however, during some updates, the built-in ASF codec would be lost which may result in the failure of ASF file on the media players.
