Abstract: A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.

This method comprises the steps of: (a) processing at least one of the regular segments into a set of particular segments, where the at least one regular segment carries a payload of a first playback duration and the payload of said set represents a second playback duration that is greater than that of the first playback duration, and where the second playback duration is sufficient to comply with a client device requirement for initiating a rendering of the event, and (b) transmitting, during an initial period, from the local access point said set of particular segments.

Abstract: The generation of hash values become popular with the storage of pin code by an authentication server, since the authentication server knows only the result of the hash function and not the pin code itself. Each time an authentication is requested, a hash function is executed on the received pin code and then compared with the stored reference hash value of the initial pin code. In order to improve the security of the hash value, it is proposed a method to produce a secure hash value (R) from a plaintext (P), said method comprising: —producing a first result (H) using an hash function of the plaintext (P), —obtaining an initial floating value (U0) by converting the first result (H) into a floating number representation of the first value (H), —updating a floating value (Un) by executing at least once a Transcendental function (TF) on the initial floating value (Un?1), —obtaining the secure hash value (R) by mixing the first result (H) with the updated floating value (Un).

Abstract: A method for identifying a peripheral device from a digital content having been received by said peripheral device from a master device located at a user end, said master device being further configured to be connected to a server located at a back end, said method comprising the steps of: receiving, by the master device from the peripheral device, at least peripheral identification data; generating, at the master device, a first mark as a function of at least a part of said peripheral identification data; and watermarking said digital content using said first mark before transmitting said digital content to said peripheral device.

Abstract: 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.

Abstract: The disclosure is related to a computer implemented method for assessing a dataset of integers, where the dataset previously is split into a plurality of subsets of the integers. In some embodiments, the integers are integer public keys for encryption or decryption. According to a first aspect, each subset in the dataset has a product data structure that is generated for the product of the integers in the subset. Each ordered pair of subsets has a remainder data structure for computing the factors of the integers in the subsets of the ordered pair. When one or more integers are to be added to the dataset, the disclosed method proposes that a subset is created to include the one or more integers be added. A product data structure is then generated for the created subset to obtain the product of the integer(s) in the created subset. Distinct ordered pairs of subsets comprising a subset from the dataset and the created subset are then identified.

Different audio streams are transmitted to each of the plurality of end points. The end points may be arranged to audibly output received audio streams, and so each end point may audibly output a respective different audio stream, i.e. the respective audio streams may be mutually different from each other.

Then, a report containing at least the metering counter differential consumption value is sent from the destination data concentrator towards the utility management center to which said utility meter is associated.

Abstract: Example embodiments provide systems and methods for managing intelligent content queuing from a secondary device for content delivery to a primary device. A content queuing system on the secondary device generates and displays a playlist interface on the secondary device. A selection of a content item to be added to a playlist is received. The content queuing system determines that addition of the content item causes a live content item to overlap with an on-demand content item on the playlist. As a result, the content queuing system creates at least two segments for the on-demand content item. The live content item is positioned between the first and a second segment on the playlist. The first segment is scheduled to end at a start time of the live content item and the second segment is scheduled to begin at an ending time of the live content item.

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.

Abstract: A method to protect a device key in a device comprising at least one secure element locally connected to at least one time programmable memory storing a global value in form of a bit string comprising locked bits and unlocked bits. The locked bits are irreversibly pre-programmed in the one-time-programmable memory during an initialization phase of the device while the un-locked bits remaining in an initial state may be programmable by the secure element. The secure element is configured to generate, at initialization of the device, a device specific value by using the global value, program the device specific value previously obtained in the one time programmable memory, and erase the global value by programming the unlocked bits of the corresponding bit string. A further object of the disclosure includes a device configured to carry out the method.
