Personalized content streams using aligned encoded content segments

Abstract

Systems and methods are described to enable a personalized content stream whose content can be dynamically altered by a user, such that multiple underlying contents can seamlessly be included within the personalized content stream. Multiple input content streams are encoded to include time-aligned splice point frames, which break inter frame dependency before and after a given splice point frame. Time-aligned segments are then generated from the encoded streams. A user may thereafter select segments of any of the input content streams to be included within a personalized content stream, and an output device may decode segments generated from different input content streams as part of the personalized content stream, without errors being introduced into the content stream due to the segments stemming from different input content streams. Thus, as user may dynamically alter the content of a personalized content stream based on their preferences.
