A February-filed, this-week-released, patent application by Google reveals endeavors towards building games on top of digital videos with the help of an interactive annotation system. In its patent filing, Google is evidently looking to patent “a method of providing an interactive game based on a digital video” using its YouTube and Google Video services.

Going by the filing, the proposed new game system by Google would enable select users – including the creator, a small group of compatible collaborators or even possibly the Internet in general – to create interactive video experiences by binding videos together as well as adding interactive annotations to each of them.

Elucidating Google’s patent filing, titled ‘Web-Based System for Generation of Interactive Games Based on Digital Videos,’ BNET said that the patent sought would pertain to “the collaborative generation of interactive features for digital videos, and in particular to interactive video annotations enabling control of video playback locations and creation of interactive games.”

The proposed system would also boast the inclusion of new sensor technology, like speech recognition, and a video analysis module with the capability of not only recognizing objects, but also assigning automatic annotations to them.

According to a description in the filing, a video can have one or more annotations linked to it, which result in the modification of the appearance of the original video submitted to an online video hosting site.
