Hello all, the implementation of the algorithm enhanced apt-X for low delay transmissions in radio is a very important task for codec manufacturers. In german public radio and television landscape a couple of different units already exists, delivered from different codec manufacturers. When they are used for contribution of audio content it is a high priority aim to guaranty the interoperability of these codecs from different manufacturers to each other. This can only be made properly by using the same rfc within the prerequisites and instructions how to implement this algorithm and the belonging signaling. The european broadcasting union EBU created a technical document, putting together all the different rfc's for the mandatory, recommend and optional functions each codec for audio-over-IP use must/should have. Therefore we urgently need this new rfc as an accepted and distributed document, because interoperability between different codecs is very important for the german broadcasters in radio as well as in tv.

This draft is a work item of the Audio/Video Transport Payloads Working Group of the IETF. Title : RTP Payload Format for Standard apt-X and Enhanced apt-X Codecs Author(s) : John Lindsay Hartmut Foerster Filename : draft-ietf-payload-rtp-aptx-00.txt Pages : 22 Date : 2013-03-13 Abstract: This document specifies a scheme for packetizing Standard apt-X, or Enhanced apt-X, encoded audio data into Real-time Transport Protocol (RTP) packets. The document describes a payload format that permits transmission of multiple related audio channels in a single RTP payload, and a means of establishing Standard apt-X and Enhanced apt-X connections through the Session Description Protocol (SDP).
