An interactive digital television system (iDTV) with a personalization module (PM) for injecting signals towards a small user-groups. The iDTV system comprises a broadcast operator (BO) for sending to subscriber units (SB: SB1-SB3) a downstream digital broadcast stream (BS) received from an interactive digital television provider (ITVP), and also comprising an interaction return channel operator (RCO) for providing interactivity between the subscriber units and the interactive digital television provider by means of a bi-directional interaction return channel (IC). The personalization module (PM) is coupled to the bi-directional interaction return channel (IC) and allows intercommunication between the subscriber units. As a result, a user can escape the limitations of the current linear TV programs and is transformed from a pure spectator into a producer and director of a collective or individual iDTV experience. In this way, when implicit or explicit groups of users are created, a user of the group may send control or data signals to the other users of the group. Data signals may be multimedia data to display and control signals may be recommendations of switching all together to another broadcasted channel. Preferably, each subscriber unit comprises a set-top box (STB) coupled to a server-side logic (L1) of the interactive digital television provider (ITVP) via the personalization module (PM) and this personalization module comprises an application logic proxy (L1′) able to interpret signals sent over the interaction return channel (IC) between the set-top box and the server-side logic in order to forward selected ones of these signals to other parts of the iDTV system. The personalization module (PM) comprises some or all the following modules: the application logic proxy (L1′), a content-reflector and forking module (L2), a community support module (L3), a presence module (L4), a terminal capability module (L5) and a broadcast data collector module (L6), interconnected through a routing/forwarding layer or link (RFL).

摘要:
Terminals (1) comprising transceivers (2) for exchanging messages (8,18) with further transceivers (12) of further terminals (11) are provided with negotiation modules (5) for exchanging negotiation messages (33,34) with further negotiation modules (15) of the further terminals (11), to increase the flexibility. The negotiation messages (33,34) define proposal actions for activations and/or deactivations of terminal capabilities and proposal reactions to the proposal actions. As a result, it is no longer necessary that each terminal has the same entire application and that each terminal is treated the same way. Individual possibilities of different terminals are used and are allowed. Capability modules (4) exchange capability messages (31,32) with further capability modules (14) of the further terminals (11). The capability messages (31,32) define terminal capabilities such as human machine interfaces (7a-7d). Application modules (6) for exchanging application messages with further application modules (16) of the further terminals (11) define at least a part of an application. Application interface modules (6a-6d) for interfacing the application modules (6) are activatable and/or deactivatable in response to proposal reactions.
