        Technical Summary
  This document describes an RTP payload format for efficient and
  flexible transporting of audio data encoded with the Adaptive
  TRansform Audio Coding (ATRAC) family of codecs. Recent enhancements
  to the ATRAC family of codecs support high quality audio coding with
  multiple channels.  The RTP payload format as presented in this
  document also includes support for data fragmentation, elementary
  redundancy measures, and a variation on scalable streaming.
