Abstract: A method of supplying information from a central source (1) to a plurality of remote user interfaces (9) relating to an interactive application. The method comprises: i) transmitting application data associated with the interactive application to the user interfaces (9); and, ii) thereafter, transmitting a real time start signal to the user interfaces (9) to enable the interactive application to begin substantially simultaneously at each user interface.

Abstract: A method and apparatus for broadcasting a scheduled interactive application to a plurality of users via respective user interfaces. Initially, setup data is placed on a broadcast carousel prior to a scheduled start time of the interactive application whereby setup data is repeatedly broadcast to the user interfaces. A status flag is broadcast to the user interfaces to indicate that the setup data has been placed on the broadcast carousel. Real time data is broadcast to the user interfaces at the scheduled start time. Electronic programme guide (EPG) data indicating a scheduled start time for the scheduled interactive application is further broadcast to the user interfaces.

Abstract: An interactive communication system comprises a central controller; and at least one remote unit connected in use to a display device, the central controller generating signals in accordance with a service function, access to all or part of which is restricted. The signals are supplied to the remote unit(s) for display on the display device. The or each remote unit includes a processor, responsive to signals from the central controller, and selectively connectable to the central controller to transmit information back to the central controller. The or each remote unit further comprises an input device and a control memory connected to the processor, the input device allowing a user to enter information, and the control memory storing access control data. The processor is responsive to the access control data to allow a user to gain access to the restricted part of the service function, and periodically supplies data to the central controller related to said access.
