I-D ACTION:draft-ietf-avt-rtp-vmr-wb-02.txt

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Audio/Video Transport Working Group of the IETF.

	Title		: Real-Time Transport Protocol (RTP) Payload and File Storage Formats for the Variable-Rate
Multimode Wideband (VMR-WB) Audio Codec
	Author(s)	: S. Ahmadi
	Filename	: draft-ietf-avt-rtp-vmr-wb-02.txt
	Pages		: 33

This document specifies a real-time transport protocol (RTP)
   payload format to be used for the Variable-Rate Multimode
   Wideband (VMR-WB) speech codec. The payload format is
   designed to be able to interoperate with existing VMR-WB
   transport formats on non-IP networks. In addition, a file
   format is specified for transport of VMR-WB speech data in
   storage mode applications such as email. A MIME type
   registration is included, for VMR-WB, specifying use of
   both the RTP payload and the storage formats

   VMR-WB is a variable-rate multimode wideband speech codec
   that has a number of operating modes, one of which is 
   interoperable with AMR-WB (i.e., RFC 3267) audio codec at
   certain rates. Therefore, provisions have been made in
   this draft to facilitate and simplify data packet exchange
   between VMR-WB and AMR-WB in the interoperable mode with no
   transcoding function involved.
