System and method for transmitting interactive services associated with broadcast contents, in real time or off line

Abstract

A system is dedicated to the transmission of additional contents (CA) accessible in interactive mode and associated with contents (CP) broadcast to primary communication terminals (TP, TP), connected to a broadcasting network (R) and associated with programming information (PI). This system comprises i) an equipment (ST) required to associate a data set (ES) with each additional content (CA), including a content definition, an address to access it and a broadcast date, depending on programming information (PI), and to transmit each set (ES) through the broadcasting network before the broadcast date contained in it, ii) primary communication terminals (TP, TP) required to store each transmitted set (ES) and to enable loading of the definition and the address contained in it during a time interval including the broadcast date contained in it, and iii) secondary communication terminals (TS-TS) each being capable of loading each definition and the associated address, stored by a neighboring primary communication terminal (TP, TP), during the associated time interval so as to immediately display and/or broadcast it and thus enable its user to select it to request transmission of the additional content associated with it to the associated address through a communication network (R).
