<p>The system (10) has a terminal (13) e.g. mobile telephone, and a portable object (14) i.e. headset, comprising receiving units to receive encoded audio and/or video data (Ec) from outside of the system. The object has determination units to determine that a decryption key is required to decrypt the encoded data that are decoded by decoding units of the terminal. The terminal and the object include a radiofrequency type contactless communication interface to exchange data relative to content decryption key (Xc), and the encoded and decoded audio and/or video data.</p> |
