Abstract
Systems, methods, and computer-readable media including instructions for processing and distributing video-on-demand (VOD) content items are disclosed. A particular method selects a group of electronic devices to receive a VOD content item. The selection is based on group-level information associated with the group of electronic devices and based on user-level information associated with individual electronic devices of the group of electronic devices. The VOD content item is transmitted to each electronic device of the group via multicast. The VOD content item has an associated validity time period, and the encrypted VOD content item is automatically made unplayable at each electronic device in the group when the validity time period has elapsed.
