Advanced Streaming Format video

What is Advanced Streaming Format video? Advanced Streaming Format video, full name for ASF video format, is an open format for streaming multimedia files containing text, graphics, sound, video, and animation. ASF video file formats consist of three objects: a Header object containing information about the file itself, a Data object containing the media streams, and an optional Index object that can help support random access to data within the file. The Advanced Streaming Format video specification has been submitted to the ISO.

Advanced Streaming Format video does not specify the way video or audio should be encoded. It just specifies the structure of video or audio stream. The most common filetypes contained within Advanced Streaming Format video file formats are WMA and WMV. Advanced Streaming Format video can also contain objects representing metadata, such as the artist, title, album and genre for an audio track, or the director of a video track. It supports scalable media types and stream prioritization.
