Abstract
This device allows an individual to participate in a television program as a function of remotely loaded data. It includes a device for reception of date (R), a keyboard (8), a clock (10) and a device for processing data entered at the keyboard as a function of the remotely loaded data and for producing a result which is a function of the processing. A device for certification is coupled to the clock (10) in order to measure the elapsed time between a characteristic instant of the running of a scenario in the device (1) and the establishment of a certification link with a server (S). A certified result is supplied by a device for comparison when there is equality, to within a given tolerance, between the measured time and a reference time computed by the server.
