| | ASFv2 Straw Man |
 | | ASF files are logically composed of three top-level objects: the Header Object, the Data Object, and the Index Object. | | | A requirement of ASF is that the Header Object must have been received for the contents of the Data Object to be interpreted. | | | Streams in a mutual exclusion relationship with each other (for example, languages) should all be listed in adjacent order (in other words, priority n, n+1, n+2, and so on), sorted in decreasing order of maximum stream bandwidth. |

| | QuickTime - Wikipedia, the free encyclopedia |
| | Other later-developed media container formats such as Microsoft's Advanced Streaming Format or by the open source Ogg and Matroska containers lack this abstraction, and require all media data to be rewritten after editing. | | | QuickTime is a multimedia technology developed by Apple Computer, capable of handling various formats of digital video, sound, text, animation, music, and immersive virtual reality panoramic images. | | | Internally, QuickTime files maintain this format as a tree-structure of "atoms", each of which uses a 4-byte OSType identifier to determine its structure. |

| | ASF (Advanced Systems Format) |
| | As potential uses went beyond streaming, it came to be called Advanced Systems Format, and it appears to function more or less as a successor-replacement for RIFF. | | | For uncompressed or losslessly compressed video, which is generally preferred to compressed, MXF may be preferred as a wrapper; this topic will be developed in a future investigation. | | | ASF uses an extensible set of GUIDs (Globally Unique IDentifiers) to identify all objects and entities within ASF files, including media types, codec types, error correction approaches, and other elements. |
