摘要： A content handling device comprises a plurality of content transformation modules that can define one or more paths from a content source module to a content sink module. The content is associated with one or more usage rules requiring one or more transformations to be applied to the content. To enforce usage rules, each content transformation module is configured to receive the content, apply a transformation to the content in accordance with the usage rules and apply a tagging operation corresponding to the transformation to the content. In some embodiments output of the content by the content sink module is prevented if all tagging operations corresponding to the usage rules have not been applied. While in some embodiments usage rule tags corresponding to the usage rules are embedded locally at the content handling device, the disclosure also extends to a content distribution system with a usage rule tag embedding functionality.

摘要： The invention relates to a method for fabricating electronic cards by A) forming a plurality of card bodies in the form of a thick sheet with a plurality of electronic units or modules embedded in the sheet; B) printing a plurality of first patterns on a first face of the thick sheet in a printing station where ink is applied on the first face; C) applying a first at least partially transparent coating on each printed first pattern, that adheres to the card body. The method can also include printing a plurality of second patterns on the inner surface of a film forming the first coating. Preferably, the printing of the first patterns is carried out in an offset type station for printing high definition patterns, essentially of the security type. The second patterns define personal data. The printed thick sheet defines an intermediate product according to the invention.

摘要： The disclosure provides a method of making watermarking data embedded in an Elementary Stream ES accessible to a receiver. The ES comprises video and/or audio data and is to be transmitted as a Packetized Elementary Stream PES in a Transport Stream TS such that the receiver can use the watermarking data to watermark the video and/or audio data in the ES without reconstructing the ES from the TS. The watermarking data identifies one or more watermarking locations in the video and/or audio data in the ES to be modified by the receiver in accordance with the watermarking data. The method comprises determining respective one or more watermarking TS locations in the TS corresponding to the one or more watermarking locations. The method further comprises embedding, in the ES, the watermarking data including watermarking location information identifying the one or more watermarking TS locations, or modifying watermarking data embedded in the ES by adding the watermarking location information. The method may further comprise subsequent to embedding or modifying the watermarking data, packetizing the ES into one or more PES packets, each packet comprising a packet header, and adding watermarking data location information identifying a location in the TS corresponding to a location of the watermarking data in the ES to the packet header of a PES packet (or in a TS header or elsewhere in the TS). The disclosure also provides a corresponding method of watermarking and related systems, devices, computer programs and Transport Streams.

摘要： A surveillance system connectable to a network, comprising a communication module and a management module; said system being configured to, during an initialization phase: a. intercept a first message being sent to a first device; b. intercept a second message said second message being a response from the first device to the first message; c. calculate a time interval between the interception of the first message and the second message; d. repeat the steps a. to c. to determine further time intervals; e. determine a distribution of said time intervals; f. store the distribution and during a surveillance phase, intercept a third message said message being sent to the first device; intercept a fourth message said fourth message being a response to the third message; calculate a new time interval between the interception of the third and fourth messages; and verify that the new time interval is within the distribution.

摘要： A display-card is disclosed for time management purpose, including a display; a clock defining a current date and time; a memory; an internal power supply; and a communication device. The memory includes a user identifier, setup information and time information. The time information includes at least a current time counter and a status information defining an active or an inactive state, the active state enabling the update with the clock of the current time counter and the inactive state disabling the update of the current time counter. The display-card further includes a receiver/transmitter to receive, via the communication device, a command to initiate the change of the status information from active to inactive state, or inactive to active state, and an actuator to initiate the display of at least the current time counter.

摘要： 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.

摘要： Methods and systems of paying for content, such as, for example, audio and/or video content, are presented. In an example method, a task to be executed using at least one device resource associated with a user device is provided. Also, the task is to be executed during streaming of a content item. The streaming of the content item to the user device is caused to terminate in response to a determination that the execution of the task using the at least one device resource has been terminated.
