SMIL (pronounced "smile") is the Synchronized Multimedia Integration
Language, and is a recently-promoted specification of the WWW
consortium. The idea is that a web page should be able to
say, use this video clip, and this audio clip, and stream them
over the WWW and play them back synchronized.
I don't know much about the technical details (anyone else?), but
it seems like a good idea. I do know that they're purposely
not specifying codecs, so there wouldn't seem to be any reason
why you couldn't send an MPEG-4 program this way (although MPEG-4
embeds a lot of its own synchronization requirements).
AAF is (my opinion here) a vaporware response by Microsoft
to the announcement of Quicktime's use for the MPEG-4 Intermedia
Format. It's an attempt to quickly come up with a "product"
which competes with QuickTime File Format (which is not really
a "product" to begin with). I don't think it's likely
to go anywhere, really.
Disclaimer: I'm not a Microsoft basher; please don't agree with
me just because you, too, hate Microsoft.
New release of saolc at the end of the week!
