A post-processing of video content in order to provide a capability to insert ad content, having a method to produce a modified video content from an original video content. The method comprising: analyzing the original video content to detect at least one marker, said marker comprising a marker surface delimited by a marker identification; loading profile data of a target user; determining, based at least on the profile data a replacement content; adjusting the replacement content into the marker surface; and replacing into the original video content the marker surface by the adjusted replacement content to produce the modified video content.

Method to insert ad content into a video scene

Malware detection logic executed by a secured device residing in a home network may receive a message from an unsecured device of a first unsecured network and intended for a destination device of the home network, the destination device comprising a security client. The malware detection logic may establish a secure communication channel between the malware detection logic of the secured device and the security client of the destination device. The malware detection logic may execute a validation test on the message to determine that the message includes malware. The malware detection logic may report an alarm to the security client of the destination device. The malware detection logic may transmit information related to the malware to a cloud computing server. The malware detection logic may prevent an application associated with the destination device from processing the message.

Secured home network

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 is described. The master device can be connected to a server located at a back end, and the method includes receiving, by the master device from the peripheral device, at least peripheral identification data. The method also includes generating, at the master device, a first mark as a function of at least a part of the peripheral identification data, and watermarking the digital content using the first mark before transmitting the digital content to the peripheral device.

Method and device for identifying a peripheral device from a digital content

Methods and systems for transmitting and receiving data, such as, for example, entertainment data, are presented. In one example, a data file is segmented into a plurality of data modules. A header is generated for each of the data modules, with the header including a module identifier for the data module associated with the header. An indication of a number of the plurality of data modules associated with the data file, and at least one multicast address from which the plurality of modules may be received via a multicast transmission, are generated and transmitted. The data modules with their associated headers are transmitted over a communication network in the multicast transmission.

Highly-scalable data transmission

A method for securing transmission of digital data in a communication network comprising a central station or a terminal and at least one device monitored by the central station via the communication network. The at least one device is configured to produce and to transmit a digital data stream to the central station or terminal. The at least one device further comprises a secure non-volatile memory for storing at least device specific information. The at least one device forms a data block based on at least the device specific information stored in the secure memory. The data block thus formed may compose additional data to be merged with the digital data stream produced by the at least one device. A modified digital data stream results from this merging operation and is transmitted by the at least one device to the central station or terminal.

Securing digital data transmission in a communication network

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.
