New mode for rfc3640: AAC-BSAC with MPEG-21 gBSD
This draft proposes a mode for RFC 3640 to support an MPEG-4 AAC-BSAC audio codec format with an optional attached bitstream description. The bitstream description employs the MPEG-21 generalized Bitstream Syntax Description Language (gBSDL). The description is attached as auxiliary header and can be used to support adaptation.
