If authentic, a new e-mail from Steve Jobs indicates that Apple and Microsoft--of all bedfellows--could be preparing to challenge the validity of open-source video codecs.
Jobs' e-mail to Hugo Roy of the Free Software Foundation Europe, coupled with a similarly worded announcement from Microsoft on Friday, is a shot across the bow of backers of the open-source Ogg Theora video codec, used by Mozilla to bring HTML5 video technology to Firefox. Both in their HTML5 strategy, which is governed by a licensing body called MPEG LA. Apple and Microsoft, along with a host of tech companies, are also members of that group.
Roy had challenged Jobs on a component of Roy took issue with that statement, as use of h.264 requires licensing payments to patent holders, as opposed to being an open standard free for anyone to use., in which Jobs argued that Apple's approach to mobile video with HTML5 technology was more open than Adobe Systems' Flash technology.
"A patent pool is being assembled to go after Theora and other 'open source' codecs now," Jobs wrote in the e-mail, which Apple did not immediately confirm as authentic. "Unfortunately, just because something is open source, it doesn't mean or guarantee that it doesn't infringe on others' patents."
, Microsoft made a similar argument that open-source codecs carry their own set of patent infringement risks.
"The distinction between the availability of source code and the ownership of the intellectual property in that available source code is critical. Today, intellectual-property rights for H.264 are broadly available through a well-defined program managed by MPEG LA. The rights to other codecs are often less clear, as has been described in the press," Microsoft said in its blog post.
The patent saber rattling could present trouble for Mozilla and Google, which supports both h.264 and Ogg Theora in its Chrome browser and is expected in May to announce plans to open-source the VP8 codec . Opera, the other major browser company in the world that uses Ogg Theora, could also be affected by any patent offensive.
Representatives from Google did not immediately respond to a request for comment. Microsoft declined to address any pending patent moves directly, but it pointed reporters back to its Friday morning blog post.
A representative for the MPEG LA group declined to comment for this story.
Updated 2:33 p.m.: Mozilla issued the following statement: "We believe that it is in the public interest for HTML5 video to be backed by multiple, open and royalty-free codecs available in a way that is consistent with the W3C license standards. We would absolutely consider H.264 if MPEG LA would make it available under open web terms as defined by the W3C standards. We stand by our position on Theora."
Updated 3:33 p.m.: Opera released its own statement from CTO Håkon Wium Lie: ""For the open Web to thrive, all media -- including video -- must be usable without paying licensing fees for codecs. Browser vendors that truly support an open web must work to establish a license-free baseline video codec."
