This document describes an RTP payload format for transporting AC-3 encoded audio data. AC-3 is a high quality multichannel audio coding system used in ATSC HDTV, DVD, film, and other media. The RTP payload format presented in this document provides mechanisms for interleaving redundant data, which can increase packet loss resilience. An intelligent method for fragmenting AC-3 frames that exceed the maximum transfer unit (MTU) is also described.
