The United States Patent and Trademark office has recently published information which relates to a series of twenty two patents which have been granted to Apple, with one in particular being awarded in the name of Steve Jobs. The patent in question outlines the methods that the company may intend to use to effectively organize episodic TV shows and points to the fact that the new television set could have digital video recording (DVR) capabilities.
While the feature could very well be a part of Apple TV, it could also likely be introduced on iTV. Specially given that Apple is reported to be meeting with a number of TV executives and recording studios with the probable intention of pushing the work on this device forward.
