An interactive multimedia broadcasting system with an end-user terminal (TV), e.g. an enhanced television system or preferably an Internet Protocol TeleVision IPTV infrastructure, adapted to receive channels of multimedia data, a content server (CS) adapted to transmit these channels to the terminal, an interactivity database (ID) adapted to receive, from the content server, notices of available interactivity on the channel transmitted to the terminal, and an interactivity server (IS) controlled by the interactivity database and adapted to transmit interactive items (Interactivity 1, Interactivity 2, Interactivity 3) to the terminal and to receive feedback from this terminal. The feedback relates to the acceptance, by the user, of the interactive data proposed by said interactive items. This system is for instance. The content server is adapted, upon acceptance by the user, to transmit the interactive data to his/her terminal (TV) on an extra channel. The system thus provides to the user, watching television, the possibility to subscribe to an extra (live or on-demand) channel, triggered by an interactive message linked to the multimedia content of the channel the user was looking to. As such, after the TV content the user was looking to will end, the user will still be able to look to content related to the subject on which he/she accepted the interactivity. |
