Systems and methods of pushing content to secondary connected devices include pushing targeted content such as interactive advertisements, banners, games or application to secondary connected devices in a household. The targeted content may reflect user preferences associated with the secondary connected devices, including user behaviour and previous interaction with various forms of content viewed on the secondary connected devices. The targeted content may be either locally cached or retrieved from an advertisement server at the time of pushing to the secondary connected devices.

Method for acquiring access rights to conditional access content

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.
