Abstract: A method is proposed for synchronizing a plurality of multimedia components selected among audio and video components of a digital multimedia processed by a media player. Each of the multimedia component is rendered on a multimedia rendering device receiving the multimedia component from the media player through a respective path. The media player is configured to obtain, for each multimedia rendering device, a delay data representative of a propagation delay of the multimedia component from the reception of the multimedia component to its rendering by the multimedia rendering device, determine a buffering delay representative of a difference between a maximum value and a minimum value among the delay data; and provide the buffering delay to at least one buffer implemented along a path of the multimedia component corresponding to the minimum value among the delay data.

Abstract: A system includes two or more communication devices. Each device includes a dedicated SDR chip with a dedicated key generator to generate a secret key shared by the two SDR chips using a physical unclonable function PUF that takes as an input configuration data and produces an output. In the dedicated key generator of each SDR chip, the PUF takes as an input configuration data and produces an output identical for the two SDR chips, that is the shared secret key or a seed to derive it. The configuration data is unique to each SDR chip, dependent on physical random factors introduced during manufacture of the SDR chip, and is adapted for the respective key generator to generate the shared secret key.
