[AVT] FW: New Version Notification for draft-hoene-avt-rtp-sbc-03

["Christian Hoene" <hoene at uni-tuebingen.de>]

Dear all,

we have uploaded a new version of the RTP payload format for the Bluetooth SBC audio codec. SBC support mono and stereo audio coding supporting variable frame- and bit rates and having a very low complexity. It is part of the open-source BlueZ protocol stack for supporting Bluetooth device in Linux. To the best of our knowledge, its IPRs will expire in one year and then its usage will be license-free even for non-Bluetooth systems. 

Having these features, the SBC is can be considered as a candidate for the Internet Wideband Audio Codecs working group (CODEC BOF). While its audio quality does not reach the efficiency of CELT, its much complexity is lower.

Best regards,

 Christian Hoene

Title:		 RTP Payload Format for Bluetooth's SBC audio codec
Creation_date:	 2009-06-15
WG ID:		 Independent Submission
Number_of_pages: 23

Abstract:
This document specifies a Real-time Transport Protocol (RTP) payload 
format to be used for the low complexity subband codec (SBC), which 
is the mandatory audio codec of the Advanced Audio Distribution 
Profile (A2DP) Specification written by the Bluetooth(r) Special 
Interest Group (SIG). The payload format is designed to be able to 
interoperate with existing Bluetooth A2DP devices, to provide high 
streaming audio quality, interactive audio transmission over the 
internet, and ultra-low delay coding for jam sessions on the 
internet. This document contains also a media type registration which 
specifies the use of the RTP payload format.
