Protocol Action: 'Real-Time Transport Protocol (RTP) Payload Format for the Variable-Rate Multimode Wideband (VMR-WB) Extension Audio Codec' to Proposed Standard

[The IESG <[e-mail]>]

The IESG has approved the following document:

- 'Real-Time Transport Protocol (RTP) Payload Format for the Variable-Rate 
   Multimode Wideband (VMR-WB) Extension Audio Codec '
   <draft-ietf-avt-rtp-vmr-wb-extension-02.txt> as a Proposed Standard

This document is the product of the Audio/Video Transport Working Group. 

The IESG contact persons are Allison Mankin and Jon Peterson.

Technical Summary

This document is an addendum to draft-ietf-avt-rtp-vmr-wb-11.txt,
which specifies the RTP payload format for the VMR-WB speech codec.
This draft updates some tables in that draft to enable support for
the new operating mode of VMR-WB standard (i.e., VMR-WB mode 4), as
defined by 3GPP2. These updates do not affect the existing modes of
VMR-WB.

Working Group Summary

This is a simple, non-controversial extension to an existing format,
to catch up with changes in 3GPP2.  3GPP2 has chosen to use
the IETF process for this media type rather than a 3GPP2
standards tree review because VMR-WB is viewed has needing
review by the AVT working group that merits the RFC 
publication.

Protocol Quality

The quality was easy to obtain as these are
trivial additions to the tables in a previously approved document.

The Responsible Area Director is Allison Mankin.  
The WG Chair shepherd is Colin Perkins.

Note to the RFC Editor

OLD:
7. IANA Considerations
   
     None 

NEW:
7. IANA Considerations
   
    This document updates the media type registered in [2].  IANA
    needs to add this document as reference to that media type
    registration and needs to modify the optional parameter
    mode-set in the registration.  Currently it reads:
              Currently, this list
         includes modes 0,1,2, and 3 [1] but MAY be
         extended in the future. If such mode-set is
         specified during session initiation, the encoder
         MUST NOT use modes outside of the subset. If not
         present, all operating modes in the set 0 to 3 are
         allowed for the session.

   IANA needs to Change "modes 0,1,2 and 3 [1]" to "modes 0, 1, 2,  
   3 and 4 [1][2]" and change "modes in the set 0 to 3" to 
   "modes in the set 0 to 4"  - [1] will be IANA's reference to
   the original VMR-WB document and [2] will be IANA's reference
   to the present document.
 
Note to IANA

An IANA action is needed which was implicit in the document if
the existing media type registration was reviewed.  See the Note 
to the RFC Editor above.
