Abstract

Video is provided in chunks to a player. Some chunks need to be computed because they are targeted to a particular user. Computing of targeted chunks is done by cloud computing instances that pop jobs from associated queues. Targeted chunks may be required sooner or later than initially expected due to the player using trick modes. In order to have targeted chunks delivered to the player at the right time, a play time tracker regularly inserts overloaded chunk requests in the manifest file. The overloaded requests comprise references to future needed targeted chunks as well as expected play out time of these chunks. Overloaded requests are verified and if it is determined that the future needed targeted chunk has not already been computed, a message for verification is transmitted to a scheduler. The scheduler verifies if measures need to be taken to ensure timely delivery of the targeted video chunks.
