Bandwidth Sharing

You can specify streams in a file that, when taken together, use less bandwidth than the sum of their stated bit rates combined. By specifying bandwidth sharing in the profile, you clarify to reading applications that the available bandwidth needed to stream the file is not what it might otherwise seem.

None of the objects of the Windows Media Format SDK change their behavior in response to bandwidth sharing information, which is provided solely so that reading applications can take it into account when determining whether a file can be played with restricted bandwidth delivery.

Bandwidth sharing is configured with a bandwidth sharing object and is added to a profile before beginning to write a file.
