Philippe Le Hegaret W3C free video codec
Video Revolution from W3C: Video Codec Must Be Free.....and Mozilla and Opera are (Nearly) Ready
Just as software for putting still images on a web page is free, so should codecs for encoding and decoding video, said Philippe Le Hegaret, Architect Domain Leader at the World Wide Web Consortium (W3) headed by Tim Berners-Lee.
Video encoding, the essential process in which video is compressed, converted and then decoded for the Web, is patented by entities including Fraunhofer, Futjisu, Sony, The Trustees of Columbia University, Microsoft and Hitachi.
These groups license software, called codecs, to be used in various formats including Flash, WMV, MPEG 4 and Silverlight. Information on this can be found at MPEG LA.
The W3C advocates a revolutionary idea: the availability of a royalty-free encoding technology so anyone can create video without having to pay.
An open-source, free codec called Theora, is about to get wide visibility with its emergence on the latest versions of the Mozilla and Opera browsers, where it is in very early Alpha. PC Week reported on this Friday with a story from Jeremy Kirk.
Theora is an evolved version of an early On2 codec, VP3, which was released by the company for the open source community. It has been developed by Xiph.
Philippe is not sure that Theora is the answer to royalty-free encoding as there are complex patent law issues, but it's an important development, he says.
In a glimpse of likely patent battles ahead, just this week, Nokia raised objections to W3C's approach to free codecs. (Earlier this week Beet's European Correspondent Mika Hentunen interviewed Nokia's top intellectual property exec in Helsinki.)
Phillipe was in New York today where he was a speaker at the Web Video Summit. He was on a panel about video search moderated by the Silicon Alley Insider himself Henry Blodget. Other panelists were Blinkx CEO Suranga Chandratillake and Thomas Wilde, CEO of EveryZing.
Tomorrow at Cisco's San Jose headquarters, Philippe will co-chair an international panel on the future of Web video protocol with participants in San Jose and Brussels connected via a video conference hook-up.
Next installment of the interview, Philippe talks about the future of video on the "semantic Web" and the organization of metadata. Stay tuned.

W3C Digging the XML Grave
Anne van Kesteren sat down with Simon Pieters to talk about the impact of XML on the mobile web, who gave a surprising insight into its failure. They discuss the level of support for XML vocabularies in mobile browsers, and what mobile browsers have been forced to do for compatibility with legacy content.

Philippe Le Hegaret W3C semantic web
Believe It: The Semantic Web is Coming to Web Video and Joost is Leading the Way
Tim Berners-Lee, the British physicist who invented the organizational system for the World Wide Web, has been an advocate for a more organized Web, something he calls the "semantic" Web.
This new system of organizing Web pages in a unified system, something akin to a giant Dewey Decimal system where pages have unique identifiers and can be cross referenced and linked, is coming to the world of video via Joost, which is inserting identifying tags called RDF's into the XML code.
Earlier this month, I interview Philippe Le Hegaret, who works with Berners-Lee at the World Wide Consortium, headquartered on the the MIT campus in Cambridge, Massachusetts. Philippe is chief architect of domain services.
He explains the current implementation of the RDF into science research documents, new software from Oracle and in videos from Joost.
Here's what Joost's CTO Dirk-Willem van Gulik said earlier this year about RDF in Technology Review:
.......Dirk-Willem van Gulik calls "XML on steroids." RDF allowed developers to write software without worrying about widely varying content-use restrictions or national regulations, all of which could be accommodated afterwards using RDF's Semantic Web linkages.
Joost's RDF infrastructure also means that users will have wide-ranging control over the service, van Gulik adds. People will be able to program their own virtual TV networks--if an advertiser wants its own "channel," say, or an environmental group wants to bring topical content to its members--by using the powerful search and filtering Âcapacity inherent in the semantic ordering of data.
How much video indexing will evolve to this "semantic" platform, is tough to say. Marshall Kirkpatrick at Read/Write Web reports that BBC is exploring the system. This is a trend to watch in 2008.
You can grab my interview with Philippe right here.
