Abstract
A terminal identification method which acquires then decodes multimedia temporal content to generate a multimedia stream in unscrambled form with at least one temporal succession of time intervals. A set of information bits for displaying an image or playing a sound being transmitted during a single time interval. The terminal identification device transmits an identification command to the terminal and the terminal triggers and alternately inhibits a predetermined modification of at least some of the information bits necessary for playing a sound or displaying an image contained in the multimedia stream to obtain a modified multimedia stream and transmits the stream as a multimedia. The device acquires the modified stream transmitted by the terminal and determines the identifier of the terminal to which it belongs on the basis of the transmitted command and the presence or absence of the predetermined modification in the acquired stream.
