One question I have is under what licensing conditions will contributions be made? The main concern, of course, would be that someone would submit a technique that someone might claim is patented. Are any conditions being laid in place to protect contributions from such a problem? While I am not sure about the final licensing situation of HEVC, at least VP9 is likely to be intended to be ultimately released under a free software license, and we know the kinds of troubles that issues surrounding software patents have caused in the past toward adoption of technologies that would otherwise be considered free software. In all honesty, even large corporations struggle with this problems, so I wonder how a competition such as this can avoid this problem. The reason I mention this is, as stated above, any contribution or modification to the reference encoder for VP9 will likely not be adopted lest it be quite clear from known patent risks. To put it bluntly, this kind of a competition, in the current legal and patent climate, has a smell about it that seems like it will do less to advance free/libre causes and be more advantageous to existing stakeholders, as the deck is stacked in their favor. Protections addressing some of the previously-raised concerns might alleviate that somewhat.

The objective indicates "without the need to request a license, enter into a business agreement, pay licensing fees or royalties, or attempt to adhere to other onerous conditions or restrictions" but then the Process section makes it only a preference, which is aligned with BCP 79. > The working group shall heed the preference stated in BCP 79: "In > general, IETF working groups prefer technologies with no known IPR > claims or, for technologies with claims against them, an offer of > royalty-free licensing." Although this preference cannot guarantee > that the working group will produce an unencumbered codec, the working > group should not proceed with publication of a codec RFC if there is > consensus that it cannot "be widely implemented and easily distributed > among application developers, service operators, and end users." For the last sentence, how about: [[ Although this preference cannot guarantee that the working group will produce an unencumbered codec, the working group also recognizes the request from the W3C for a royalty-free standard Web infrastructure and should not proceed with publication of a codec RFC if there is consensus that it cannot "be widely implemented and easily distributed among application developers, service operators, and end users." ]] > The working group will coordinate with the ITU-T (Study group 16) and > ISO/IEC (JTC1/SC29 WG11), with the intent of submitting the completed > codec RFC for co-publication by the ITU-T and ISO if the co-publishing > organizations find that appropriate. Looking at the list of APIs that you mention in the Process, the work is relevant to our HTML (HTML5, Media Source Extensions), Device APIs and WebRTC Working Groups. How about adding the following paragraph at the end of the collaboration section: [[ The working group will also coordinate with the W3C, in particular with the HTML, Device APIs and WebRTC Working Groups, since one of the core technical considerations is to use the resulting codec in Web APIs. ]] Also, one minor correction: s/the MediaSource API/the Media Source Extensions/ Philippe From tterribe@xiph.org Tue Feb 19 05:56:48 2013 Return-Path: X-Original-To: video-codec@ietfa.amsl.com Delivered-To: video-codec@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 6A2F121F8D02; Tue, 19 Feb 2013 05:56:48 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -2.677 X-Spam-Level: X-Spam-Status: No, score=-2.677 tagged_above=-999 required=5 tests=[BAYES_00=-2.599, HELO_MISMATCH_ORG=0.611, HOST_MISMATCH_COM=0.311, RCVD_IN_DNSWL_LOW=-1] Received: from mail.ietf.org ([64.170.98.30]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id mIAqjAUiJ38h; Tue, 19 Feb 2013 05:56:48 -0800 (PST) Received: from smtp.mozilla.org (mx2.corp.phx1.mozilla.com [63.245.216.70]) by ietfa.amsl.com (Postfix) with ESMTP id 04A3F21F88EA; Tue, 19 Feb 2013 05:56:47 -0800 (PST) Received: from [132.177.252.38] (unknown [132.177.252.38]) (Authenticated sender: tterriberry@mozilla.com) by mx2.mail.corp.phx1.mozilla.com (Postfix) with ESMTPSA id 87478F210D; Tue, 19 Feb 2013 05:56:47 -0800 (PST) Message-ID: <5123849E.6030709@xiph.org> Date: Tue, 19 Feb 2013 05:56:46 -0800 From: "Timothy B.
