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 Date : 2004-8-13 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.
