Abstract
Segments of media content may be shared amongst multiple requesting entities in a cDVR environment. In one illustrative example, a first request to initiate recording of media content at a first start time is received from a first requesting entity. In response, a first encrypted copy of a first plurality of content segments of the media content is cached in network memory, in a first encryption window associated with a first encryption key. A first manifest including a first set of URLs is generated and sent to the first requesting entity, where URLs of the first set reference a first identifier of the first encryption window and a respective one of the content segments. If a second request to initiate recording of the media content is received from a second requesting entity at a second start time that does not exceed an interval threshold, no additional copy needs to be made. Here, a second manifest including a second set of URLs is generated and sent to the second requesting entity, where URLs of the second set also reference the first identifier of the first encryption window and a respective one of the content segments.
