    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 method for providing video and audio perspectives of audio/video content is presented. In an example embodiment, a media content item is received that includes audio/video content having at least one video perspective and a plurality of audio perspectives for the at least one video perspective. The at least one video perspective is provided with a first one of the plurality of audio perspectives for presentation on a display device. During the providing of the at least one video perspective with the first one of the plurality of audio perspectives, a first command is received from a media application configured to allow a user to select among the plurality of audio perspectives. Responsive to the first command, the video perspective is provided along with a selected second one of the plurality of audio perspectives in substitution of the first one of the plurality of audio perspectives for presentation on the display device.
