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. Working Group Summary The first predecessor to this document appeared in late 2002. Since then the document has progressed steadily with strong guidance from the AVT Chairs. It was accepted as a Working Group item in August 2004. Working Group Last Call drew one comment on the media types list and a final Chair's review. All comments have been resolved. Document Quality The authors have implemented the content of the document. Media type review was requested for the three media types on 19/2/2008.
