The US Patent Office has recently published a patent application by Disney Enterprises which appears to be the groundwork for Disney’s announced digital rights management (DRM) technology dubbed ‘Keychest.’
The technology is intended to allow an individual to purchase the right to a movie or a song or book or any other type of protected content and be able to play that same content on any number of multimedia devices with just the single purchase. For example, songs purchased through iTunes are limited not just to iPod/iPhone/iTunes devices, but specific ones. With ‘Keychest’ technology, that song might also be able to be played on a PC using any copy of iTunes (or even another application), on any other mobile device, etc. The same would apply for movies. For example, purchase the latest Disney film on DVD and immediately be able to stream it on your friend’s computer or play it on your cell phone, all at no additional cost.
