摘要： The present invention concerns a method for building a watermarked content for sending to at least one user unit having a user unit identifier, the watermarked content comprising a first series of packets, at least some from the first series of packets being available in at least two different qualities, wherein said method comprises the steps of: generating a watermark based on at least the user unit identifier, the watermark being formed by a first series of values from a predetermined set of values; mapping each of the at least two different qualities to one from the predetermined set of values; building the watermarked content by sequentially selecting from the first series of packets, a packet having a quality corresponding to each value from the first series of values forming the watermark. It further concerns a method for transmitting such a watermarked content

摘要： A method for pairing a multimedia receiver connected to an IP network with at least one mobile equipment connected to a mobile network using a communication protocol different from the IP network. A unique identifier of the mobile equipment is introduced into an application on the multimedia receiver. The latter transmits, to the mobile equipment, a message comprising a pairing request and a command for acquiring a unique public address of the multimedia receiver, said mobile equipment being identified by an address associated to the unique identifier. The mobile equipment receives the message and transmits a response message to the multimedia receiver identified by the unique public address, said response message comprising unique identifier. The multimedia receiver verifies the unique identifier in the response message by comparing it with the unique identifier introduced into the application. If the verification is successful, the mobile equipment pairs with the multimedia receiver.

摘要： The disclosure provide methods and content consumption devices that enable a scene, for example a 360° scene, that is larger (i.e. has more pixels in at least one dimension) than a display format of the content consumption device to be displayed. Constituent scene views are received individually by the content consumption device, for example as broadcasts, and are combined, for example stitched together, at the content consumption device to output a part of the scene that fits in the display format. The part of the scene (and hence the required constituent streams) to be displayed are determined by a signal, for example a navigational input from a user, enabling the user to navigate in the scene.

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 for authenticating a user to a provider, among a plurality of providers. The method uses an authentication device comprising, for each of provider, a record comprising a pairing key and first data, both as shared data. Provider authentication data comprises a first cryptogram obtained by encrypting said first data with said pairing key. Authenticating provider authentication data is performed at the authentication device by the steps of decrypting said first cryptogram by means of the pairing key stored in one of said records, then comparing the result of this decryption with first data resulting from pairing data stored in said record, if the comparison does not indicate a match, then processing again the previous decryption and comparison steps by using the pairing key of another record until each of said records stored in the authentication device has been processed.

摘要： A method of acquiring access rights to conditional access content. The method comprises receiving an access right on a first terminal through a first communication channel; storing said access right in said first terminal; sending a request for said conditional access content to a content provider, said request containing at least an identifier of an account to which said first terminal is associated, an identifier of the requested content and a piece of information concerning said access right; verifying, by said content provider, the authenticity of said access right using said piece of information concerning the access right; and when there has been a successful verification, marking said access right as used, and sending said conditional access content to at least one terminal linked to said account. The first terminal using near field communication technology (NFC) during at least one transfer of said access rights.
