From Gen-ART review by Michael Patton: ...if the document is being changed due to some other issues, the editors might consider these changes as well. Minor comments -------------- I do not believe that all the Normative references are, in fact, Normative. In particular,  and  are only referenced in a "for example ... could be used" style, which is clearly only Informative. There is a transcoding case that I think might be a useful example, but doesn't appear anywhere in the document. If there is a rewrite, you may wish to mention it somewhere for additional support. Perhaps in the introduction. The case I'm thinking of is where the two ends do not support a common bandwidth, perhaps one end only supports high quality (and therefore high bandwidth) video, but the other end is bandwidth constrained and requires a different encoding with lower BW requirements. For most combinations like this, it would be possible to have a transcoder that solves the mismatch. It might even be offered as a standard option at the ingress to the lower BW portion of the network. I note that this document along with references  and  actually forms a loosely coupled set, where I understand this document is an informational overview and the other two are details of the two approaches. I applaud this approach, if that's what is intended, but would like to see that relationship described in this document. Once again, a suggestion for better clarity, but not worth holding up the document if nothing else is being changed. ---------------------------------------------------------------- The following editorial issues are noted for the convenience of possible copy editors but are not part of the technical review. Clarity ------- In Section 3 very near the top of Page 5, you have a reference for 3pcc to reference . Would it also be productive to reference  as well there? Also, that paragraph has no reference for the bridge model. Should  be referenced? Typos ----- Section 3.1: "This model also allows to invoke" => "This model also allows invoking"
