All,

The following is a summary of the agenda item "Highlights of VMR-WB RTP Payload and Storage Format".

A new Internet Draft (ID) has recently been proposed for VMR-WB; i.e., the new cdma2000 wideband speech codec standard. 

Due to algorithmic similarities between VMR-WB and AMR-WB and understanding that the two codecs are interoperable, a large part of RFC3267 has been reused in VMR-WB payload and storage formats. It was ensured that the reuse of the existing formats for AMR-WB has not compromised the optimal operation of VMR-WB; given the differences between the native systems for which the two codecs have been developed.   

I will provide a short presentation on 11/10/03, highlighting the important aspects of this new ID. The outline of my presentation is as follows:

* Background on VMR-WB
* Motivation for the Codec Interoperability
* Interoperability with AMR-WB
* Overview of VMR-WB RTP Payload Format
* Overview of VMR-WB Storage File Format
* Applications of VMR-WB

Your feedback and comments are welcomed.
