    摘要： A method is proposed for securing the processing of an initial digital asset according to at least one processing step delivering an output digital asset from an input digital asset function of said initial digital asset. According to such method, a producer electronic device executes:
    - creating (S410) an initial NFT assigned to a producer wallet, in a blockchain, the initial NFT being associated with the initial digital asset, the initial NFT comprising input access condition to the initial digital asset and, for said at least one processing step, the initial NFT comprises: post-processing access conditions to the input digital asset after the execution of the processing step and output access conditions to the output digital asset delivered by the processing step,
    - assigning (S412) the initial NFT to a wallet, in said blockchain, associated with a first processor electronic device implementing a first processing step.

    摘要： A broadcast receiving system is disclosed that verifies a current digital certificate extracted from a digital broadcast signal using a previous digital certificate previously stored as trusted. The current and previous digital certificates are associated with digital signatures with which data received with the broadcast signal has been signed. Also disclosed is a system for signing application data to be broadcast together with a digital certificate in a digital broadcast signal. A current digital certificate attesting the validity of a digital signature attached to broadcast data is in turn signed with a digital signature using one or more previous private keys associated with respective previous certificates identifying the issuer of the current digital certificate. These disclosures are in particular applicable to HbbTV.

    摘要： A method is proposed for notifying at least one client module (100cma, 100cmb, 100cmc) implemented in a wireless device communicatively connected to a wireless communications network that respective specific data are available in a service module (150sma, 150smb, 150smc) implemented in a server communicatively connected to the wireless communications network. According to such method, a notification client device (100d) implemented in the wireless device executes:
    - receiving (S410) a notification, sent by a notification service device (110d) implemented in a server communicatively connected to the wireless network, comprising information that, for at least one client module, respective specific data are available in a server communicatively connected to the wireless communications network; and
    - notifying (S430) the at least one client module that respective specific data are available in a server.

    摘要： The present disclosure generally relates to user response analysis. For example, aspects of the present disclosure include systems and techniques for identifying a response of a user to a particular action. One example method includes obtaining, via a user prediction system, one or more actions associated with a subscription service; obtaining, via the user prediction system, user characteristics associated with each user of one or more users of the subscription service; determining, via the user prediction system, a probability of a reaction of the one or more users in response to each of the one or more actions based on the user characteristics; and providing a user response prediction output based on the probability of the reaction.

    摘要： A method is proposed for synchronizing a plurality of multimedia components selected among audio and video components of a digital multimedia processed by a media player. Each of the multimedia component is rendered on a multimedia rendering device receiving the multimedia component from the media player through a respective path. The media player is configured to:
    - obtaining (5420), for each multimedia rendering device, a delay data representative of a propagation delay of the multimedia component from the reception of the multimedia component to its rendering by the multimedia rendering device,
    - determining (S450) a buffering delay representative of a difference between a maximum value and a minimum value among the delay data; and
    providing (S460) the buffering delay to at least one buffer implemented along a path of the multimedia component corresponding to the minimum value among the delay data.
