What is ASF?
Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming
Format) is Microsoft's proprietary digital audio/digital video container format,
especially meant for streaming media. ASF is part of the Windows Media framework.
ASF is based on serialized objects which are essentially byte sequences identified
by a GUID marker.
The format does not specify how (i.e. with which codec) the video or audio
should be encoded; it just specifies the structure of the video/audio stream.
This is similar to the function performed by the QuickTime, AVI, or Ogg container
formats. One of the objectives of ASF was to support playback from digital media
servers, HTTP servers, and local storage devices such as hard disk drives.
The most common filetypes contained within an ASF file are Windows Media Audio
(WMA) and Windows Media Video (WMV). Note that the file extension abbreviations
are different from the codecs which have the same name. Files containing only
WMA audio can be named using a .WMA extension, and files of audio and video content
may have the extension .WMV. Both may use the .ASF extension if desired.
ASF files 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, much
like the ID3 tags of MP3 files. It supports scalable media types and stream prioritization;
as such, it is a format optimized for streaming.
The ASF container provides the framework for digital rights management in Windows
Media Audio and Windows Media Video. An analysis of an older scheme used in WMA
reveals that it is using a combination of elliptic curve cryptography key exchange,
DES block cipher, a custom block cipher, RC4 stream cipher and the SHA-1 hashing
ASF container-based media is usually streamed on the internet either through
the MMS protocol or the RTSP protocol.
What is M4R?
M4R is the standard file format for Apple iPhone ringtones. The M4R is encoded
with Advanced Audio Coding (AAC). The AAC is a standardized, lossy compression
and encoding scheme for digital audio. AAC has been standardized by ISO and IEC,
as part of the MPEG-2 and MPEG-4 specifications.
