"Open Standard" means patent royalty free. You'll find plenty of Apple pundits like Gruber who'll dispute this due to Apple getting behind H.264 for web video, but Apple themselves (and standards bodies like MPEG or W3C) don't use the term incorrectly. Apple have sailed pretty close to the wind though, using phrasing like "open and standard technologies" and then including technologies that are standard, but not open standards.

I thought I caught them referring to something that wasn't as an "Open Standard" in the keynote but I've not had time to check, but certainly they've been very careful not to previously. (I think the phrasing might have been "open industry standard").

But in, for example, Thoughts on Flash, the phrase "open standard" is used repeatedly to refer to HTML5, CSS, Javascript etc. and portrayed as a very good quality for these things to have but when H.264 is mentioned it is referred to just as an "industry standard".

Also Skype, along with Broadcom and Xiph, are working on a royalty-free voice codec at IETF and have offered their codecs and patents as the basis for that work. For video Skype use VP7 and Google hasn't made any big announcement but it's clear they're positioning VP8 as a Video Chat codec as well as for Web Video within the WebM container. I see Apple's announcement mostly as a half-hearted spoiler for that, kind of like Microsoft's OOXML versus ODF.
