Guidelines for Development of an Audio Codec within the IETF
Abstract
This document provides general guidelines for work on developing and
specifying an interactive audio codec within the IETF. These
guidelines cover the development process, evaluation, requirements
conformance, and intellectual property issues.

1. Introduction
This document describes a process for work in the IETF codec WG on
standardization of an audio codec that is optimized for use in
interactive Internet applications and that can be widely implemented
and easily distributed among application developers, service
operators, and end users.
2. Development Process
The process outlined here is intended to make the work on a codec
within the IETF transparent, predictable, and well organized, in a
way that is consistent with [PROCESS]. Such work might involve
development of a completely new codec, adaptation of an existing
codec to meet the requirements of the working group, or integration
of two or more existing codecs that results in an improved codec
combining the best aspects of each. To enable such procedural
transparency, the contributor of an existing codec must be willing to
cede change control to the IETF and should have sufficient knowledge
of the codec to assist in the work of adapting it or applying some of
its technology to the development or improvement of other codecs.
Furthermore, contributors need to be aware that any codec that
results from work within the IETF is likely to be different from any
existing codec that was contributed to the Internet Standards
Process.
