Apple is expected to revolutionize television with a set of its own later this year, and while we’re all expecting the device to feature Siri, there’s very little else we know about it. But according to a relatively new Apple patent, credited to Steve Jobs, it may also feature digital video recording capabilities that allow you to save your favorite shows for viewing at a later date.
