摘要： A method includes obtaining an association of a client device with the secondary device. The method further includes identifying a triggering event related to an operation of the secondary device. The method also includes responsive to identifying the triggering event, sending, by the secondary device via a network, a message to the client device with a request for information related to the operation of the secondary device. The client device may have a client device interface configured to present the message and to receive input pertaining to the message. The method includes receiving, via a network, input pertaining to the information from the client device. The method further includes configuring the secondary device to perform the operation at the secondary device using the input received from the client device.

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： The present invention concerns the field of television systems, in particular involving a main user device and a secondary user device interacting together.
It is proposed a method to create interactivity between a main reception device being connected to a main TV screen and via wireless communication means with at least one secondary device, the method comprising the steps of :
- receiving a main stream comprising audio/video content and interactive data comprising at least a signal indicating the availability of the ongoing interactive experience related to the audio/video content of the main stream,
- extracting the interactive data from the main stream,
- obtaining a main interactive application related to the interactive data by the main reception device,
- obtaining a secondary interactive application related to the interactive data by the secondary reception device,
- loading the main interactive application into a software module of the main reception device,
- loading the secondary interactive application into a software module of the secondary reception device,
- executing the main and the secondary interactive application with all or part of the interactive data,
- collecting by the main interactive application of the main reception device, result of user's interactions made on the secondary device during execution of the secondary interactive application,
- processing the received user's interaction by the main interactive application to produce a result,
- displaying the result on the main viewing screen together with the audio/video content so as to create an interactive experience.
