Real-Time Transport Protocol Payload Format and File Storage Format for the Adaptive Multi-Rate and Adaptive Multi-Rate Wideband Audio Codecs
RFC 3267, “Real-Time Transport Protocol Payload Format and File Storage Format for the Adaptive Multi-Rate and Adaptive Multi-Rate Wideband Audio Codecs”, is a Proposed Standard document published in July 2002 by J. Sjoberg, M. Westerlund, A. Lakaniemi, Q. Xie. It has been obsoleted by RFC 4867 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document specifies a real-time transport protocol (RTP) payload format to be used for Adaptive Multi-Rate (AMR) and Adaptive Multi-Rate Wideband (AMR-WB) encoded speech signals. The payload format is designed to be able to interoperate with existing AMR and AMR-WB transport formats on non-IP networks. In addition, a file format is specified for transport of AMR and AMR-WB speech data in storage mode applications such as email. Two separate MIME type registrations are included, one for AMR and one for AMR-WB, specifying use of both the RTP payload format and the storage format. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
