Windows-media-formats meaning

Windows Media formats are supported in many software and hardware-based players as well as Microsoft's own software-based Windows Media Player. The foundation container format for Windows Media is the Advanced Systems Format (ASF) file, which holds audio, video, meta-data (titles, author, etc.), indexes and scripts.WMA (Audio) and WMV (Video)When Windows Media audio codecs are used, the resulting file is given a .WMA extension. When Windows Media video codecs are used, files have a .WMV extension. For non-Windows codecs, the .ASF file extension is used, and WMA and WMV files can be renamed with the .ASF extension for compatibility with earlier players. See WMA Lossless.StreamingWindows Media audio and video files can be downloaded intact and played, or they can be streamed from a website when used in conjunction with Microsoft's Windows Media Services on a Web server. In fact, ASF originally stood for "Active Streaming Format," but was changed to Advanced Systems Format to eliminate the streaming-only connotation. See Smooth Streaming.Metafile FormatsWindows Media provides XML-based metafile formats for holding playlists, content descriptions and the location of the ASF, WMA or WMV file on a local or remote server. These files are called "redirectors" (see below).
