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: An aircraft comprises a fuselage having a compartment, and a fire suppression system for delivering fire suppressant to the compartment.

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: 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: Aspects of the present disclosure relate to systems and methods for automated fire detection, such as in aircraft galleys, or other areas where power sources may result in fire or smoke. The system includes one or more detectors to monitor for smoke or fire in an aircraft galley. Upon detection of smoke or fire, a signal is sent from the one or more detectors to a controller. In response to the incoming signal, the controller sends a signal to a galley power source. The signal provided to the galley power source ceases the application of power to one or more devices located in the galley, extinguishing the source of the fire or smoke. The controller may also send a notification signal to alert the crew to the potential fire hazard. A method of operation is also disclosed.
