Hi, I have privately communicated my skepticism about this draft before. The content of this draft may have been appropriate in an SVC requirements document, published in 2005 or so. Indeed, most (if not all) of the information presented here is available in the SVC requirements documents used in JVT. There is nothing in the document that refers to RTP, related signaling, the transport of SVC over IP, or other aspects the IETF is concerned about. No codepoints are defined, no novel technical concepts are described. No normative content is presented. At best, the draft contains an IMO quite obvious application example for the use of SVC. As the draft adds or removes nothing of substance, I have no concern that it would create a problem for the technology defined in the SVC payload draft. Therefore, I'm not violently objecting its inclusion. At the same time, though, I believe that the signal to noise ratio of the SVC draft, after inclusion, would go down. Therefore, I'm mildly against including it. As for the relationship with MVC: there is none, except perhaps for the well understood feature of MVC that allows stereo/3d content to be also displayed as flat content on a 2d display. Which, again, has been documented in JVT.
