Greetings, Below is a summary of the issues I will be discussing at the Thursday, 20th March at 09:00-11:30 AVT time slot concerning the following agenda item: RTP Payload Format for RGL Codec (Ramalho) 15 min draft-ramalho-rgl-desc-01.txt draft-ramalho-rgl-rtpformat-01.txt The text versions of these drafts can be found at: http://www.ietf.org/internet-drafts/draft-ramalho-rgl-desc-01.txt http://www.ietf.org/internet-drafts/draft-ramalho-rgl-rtpformat-01.txt and html versions (easier to view) may be found at: http://www.winlab.rutgers.edu/~ramalho/rgl_codec_01.html http://www.winlab.rutgers.edu/~ramalho/rgl_rtp_01.html 1) RGL Codec draft (~5 min): *The new RGL codec draft describes a revision to the previous version of the RGL codec. The reason the RGL codec was revised was to accommodate a simple RTP payload format for it. * To create a Table of Contents (TOC) required for some of the packetization formats proposed in the RTP payload draft, the RGL codec was revised to create seven "reserved first RGL bytes" that are never produced as the first byte of a RGL frame. * The revision was made backwardly compatible; that is, an RGL frame produced by the revised encoder will be successfully decoded by the previous version decoder. 2) The RGL RTP payload format draft (~10 min): This draft proposes several RTP payload formats for RGL encoded frames. When more than one RGL frame is placed in a RTP payload, a TOC is created at the beginning of the RTP payload. This draft proposes a few specialized TOCs and one generic one to determine the boundaries and necessary parameters of the RGL frame(s) contained in the RTP payload. 3) Next Steps and Q&A Regards, Michael Ramalho Michael A.
