In one embodiment, a method includes receiving a stored copy request indicating data and including a request identifier, scheduling publication of the data to an object store, and sending a subscription request indicating the data and the request identifier to the object store. In another embodiment, a method includes receiving a publication request indicating data to be copied, wherein the publication request is a recording request indicating a channel and a timespan, receiving one or more subscription requests for the data, receiving the data, and generating a copy of the data for each subscription request.

Storage system

In one embodiment, a method, system and apparatus are described for cloud digital video recorder optimization. A cloud based storage unit stores recorded content items in response to recording requests by users from among a plurality of users, each recorded content item belonging to at least one content item type category and each user belonging to at least one user type category. A processor receives log files tracking the recording requests, applies a data-driven procedure to the log files on a basis of at least one of: the at least one content item type category and the at least one user type category, and assigns each recorded content item to a group associated with a second plurality of users and a co-related group of content items of a given content item type category and determines times to delete each recorded content item from the cloud based storage unit. Related methods, systems, and apparatus are also described.

Storage system for recording and retrieving data copy for multiple users

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.

Cloud DVR Optimization

In one embodiment, a cloud digital video recorder system includes a broadcast content receiver operative to receive broadcast content, a spill agent operative to generate a plurality of different time-period, non-user initiated, recording requests, and a content recorder operative to receive a plurality of user-initiated recording requests of a plurality of users, receive the plurality of different time-period, non-user initiated, recording requests of the spill agent, record the broadcast content into a content storage according to the plurality of user-initiated recording requests and the plurality of different time-period, non-user initiated, recording requests, receive a user-initiated retroactive recording request for a first portion of the broadcast content which has already been recorded to the content storage, and generate a pseudo-recording from the first portion of the broadcast content stored in the content storage according to the user-initiated retroactive recording request. Related apparatus and methods are also described.

Cloud DVR system with retroactive recording

In one embodiment, a method includes receiving a segment of content, determining that the segment is referenced by at least one active record of a recordings database, and, responsive to the determination, storing the segment.

Segmented video content storage

In one embodiment, a first value is computed on a networked computing device, the first value being associated with storing a recording of a broadcast video at a first cloud storage device situated in a first one of a plurality of regions, for playback on a remote client device situated in the first one of the plurality of regions, the first value being a measure of user consumption patterns and use of computing and network resources. A second value is computed on the networked computing device, the second value being associated with storing the recording of the broadcast video at a second cloud storage device situated in a second one of the plurality of regions, for playback on a remote client device situated in the second one of the plurality of regions, the second value being a measure of user consumption patterns and use of computing and network resources. The first and second values are compared on the networked computing device in order to determine a preferred storage region, the recording of the broadcast video is stored on the one of the first cloud storage device and the second cloud storage device in the preferred storage region, and the one of the first cloud storage device and the second cloud storage device in the preferred storage region is instructed to store the recording of the broadcast video. Related hardware, systems, and methods are also described.
