System and method for transmitting in real time or differs from associated interactive services has diffuse content

A primary communication terminal (TP1) is connected to a broadcast network (R1) to receive broadcast content (CP) associated with additional content (CA) (accessed interactively and associated information (PI)) . The primary terminal (TP1) is loaded, i) storing data sets (ES) defined by a device (ST) based on information (PI) and each including a definition of additional content (CA), an address enabling access this additional content (CA) and a release date, and broadcast by the broadcasting network (R1) before the broadcast date they contain, and ii) to allow loading by at least one communication terminal secondary (TS11) neighbor, definition and address contained in each set (ES) which is stored for a time interval including the release date on it. Thus, the secondary terminal (TS11) can load a definition and the associated address during the associated time interval, and display to allow the user to select to request, via a communication network (R2) transmission of additional content associated with it, to the address.
