I never assumed so.

Sorry. I thought you were confusing MS's and Real's approaches to bandwidth usage with QT's. I think Ben's book on compression talks about these technologies.

QuickTime uses "Instant-on" and "Skip Protection".
... which have not that much to do with stream switching. Wondering why you mention those two.

The reason I mentioned these is because they're used to deal with different bandwidth situations.

As for stream switching QTSS does "thinning" of the stream, which is not switching much though. My understanding is that the main difference between "Intelligent Streaming" and "SureStream" is that SureStream encodes all video versions at the same window size while Intelligent Stream actually contains more than one resolution.

My understanding is that the MPEG-4 spec does allow for stream switching in a very powerful way (kind of a mix between thinning and intelligent stream) but AFAIK QTSS/QT has no support yet.
