    摘要： 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.

    摘要： A media server machine may be configured to provide media content within a datastream. This datastream may be provided to a media device that is configured to present the media content on a display. Also, this datastream may contemporaneously contain an “app-sync indicator” for the media content. The app-sync indicator is a data structure that signals the media device to launch an application on a companion device. By providing the app-sync indicator contemporaneously with the media content in the datastream, the launching of the application on the companion device may be synchronized with the media content. The app-sync indicator may specify the application to be launched. Also, the app-sync indicator may specify supplemental content to be presented by the launched application on the companion device.
