− | HTML is the standard, set by [[w3c]], for how to write webpages. HTML5 was supposed to include a standard way to add video to webpages, but after lengthy discussions about [[software patents]], the drafters announced on June 30th 2009<ref>http://lwn.net/Articles/340132/</ref> that they could find no freely implementable video format to recommend.
| |
− | | |
− | The two main candidate formats were [[H.264]] and [[Ogg Theora]], but the former is heavily encumbered by patents while the latter's future was deemed questionable because, as [[Google]]'s Chris DiBona said:

− | A third option discussed was to [[use software from 20 years ago]]: MPEG-1.
| |

− | HTML is an open [[harm to standards|standard]] and aims to be patent-free. Consequently, the risk of patent encumbrances is posing a real problem in extending HTML to provide a standard video interface.
