Abstract: Systems and methods for managing provisioning of keys prior to a key rotation are provided. A license server generates a license that is associated with a renewal time. The renewal time is a time that is prior to a key rotation time, and triggers a receiver device to send a renewal request prior to the key rotation time. The renewal time may be a randomized time prior to the key rotation time that differs for different receiver devices. The license is transmitted to the receiver device. The license server then receives a renewal request from the receiver device that is triggered at the renewal time. The license server generates a next license that comprises a next key, whereby the next key is a decryption key for decrypting the encrypted signal after the key rotation time. The next license is transmitted to the receiver device prior to the key rotation time.

Abstract: A machine controls a device configured to record media content in accordance with a recording schedule. The machine detects that the device is scheduled to record first media content. The machine accesses a first vector that describes the first media content and in which a first value of a dimension indicates whether a data track exists in the first media content. The machine detects that the device has access to second media content described by a second vector in which a second value of the dimension indicates whether the data track exists in the second media content. The machine may then determine that the first media content is a version of the second media content, based on a comparison of the first and second vectors. The machine may next determine whether the scheduled recording of the first media content is to be performed or canceled by the device.

Abstract: Example embodiments provide systems and methods for replacing recorded media content. In an example method, at least one media content source is searched for a media content item recorded to storage of a first media content device. Based on the media content item being found at a first media content source of the at least one media content source, a recording of the media content item to storage of a second media content device is scheduled based on the media content item being recordable from the first media content source at the second media content device. Based on the media content item not being recordable from the first media content source at the second media device, the availability of the media content item is indicated to the second media content device.

Abstract: Systems and methods for providing access to live content based on content rating levels are provided. A digital receiver receives an indication of a license rotation during presentation of a live content stream delivered over the Internet to the digital receiver of a user. In response to receiving the indication, the digital receiver accesses, from a license server, a license corresponding to the license rotation. The digital receiver extracts a rating level of content from a field of the license and compares a user setting for the user with the rating level of the content. Based on the comparing, the digital receiver determines whether to provide continued access to the live content stream.
