A More Loss-Tolerant RTP Payload Format for MP3 Audio
R. Finlayson · 2001
This document describes a RTP (Real-Time Protocol) payload format for transporting MPEG (Moving Picture Experts Group) 1 or 2, layer III audio (commonly known as "MP3").This format is an alternative to that described in RFC 2250, and performs better if there is packet loss.In this document we define an alternative RTP payload format for MP3 audio.This format uses a data-preserving rearrangement of the original MPEG frames, so that packet boundaries now coincide with true MP3 "Application Data Units", which can also (optionally) be rearranged in an interleaving pattern.This new format is therefore more data-efficient than RFC 2250 in the face of packet loss.
