The digital receiver (13), which can be integrated with the digital television, is configured to process the broadcast digital information stream (F). This processing is generally of the demodulation, decoding, decryption or other type. Once the digital information stream (F) has been processed, the latter is sent to a means of rendering said digital information stream generally integrated with the television. This means of reproduction is of the LCD screen, plasma, OLED, SED, or other type, for the video components, and the type of amplifier and speakers for the audio components. In practice, the digital receiver (13) comprises an electronic circuit that may include a tuner, a demodulator, a decoder, a microprocessor, one or more memories of the flash, magnetic, optical or other type, etc. With the digital information stream (F), the digital receiver (13) receives the interactivity information (I). Similarly, when the broadcast signal (D) contains synchronization information (S), the digital receiver receives, with the digital information flow (F), said synchronization information. A transmission means then sends the interactivity information (I) received by the digital receiver (13), and possibly the synchronization information (S) received by the digital receiver (13), to an additional terminal (16). The latter will be described in more detail in the following description. The transmission means is in the form of an electronic circuit that can be integrated in the digital receiver (13), or integrated in a PCMCIA module connected to a common interface port fitted to said digital receiver, or integrated in a connected USB module. to a USB port fitted to said digital receiver, or remote in a box connected to said digital receiver by wired connection (Ethernet, HDMI, or other) or by wireless connection (Wifi, Bluetooth, infrared, or other).

The attendant terminal (16) is configured to exploit the interactivity information (I) to access the interactive digital television service. In a first case, when the interactivity information (I) contains one or more informative data, the auxiliary terminal (16) displays said information or data. In practice, the subsidiary terminal (16) comprises a microprocessor which, when executing the steps of a computer program stored in a memory, is configured to: extract the data contained in the interactivity information (I) received , typically the informative data, - displays the informative data on a screen of the type of that previously described. In a second case, when the interactivity information (I) contains a computer program, the subsidiary terminal (16) executes said computer program. In practice, the ancillary terminal (16) comprises a microprocessor which, when it executes the steps of a computer program stored in a memory, is configured to: extract the data contained in the interactivity information ( I) received, typically the computer program relating to the interactive digital television service, - installing and executing the computer program relating to the interactive digital television service. This computer program can then be configured to communicate with the server (15) of the interactive service via the telecommunications network (18).

In a third case, when the interactivity information (I) contains a connection link to the server (15) of the interactive service, the subsidiary terminal (16) connects to the interactive digital television service via the telecommunications network (18). ). In practice, the subsidiary terminal (16) comprises a microprocessor which, when executing the steps of a computer program stored in a memory, is configured to: extract the data contained in the interactivity information (I) received , typically the connection link to the server (15) of the interactive service, - connect to the server (15) of the interactive digital television service via the telecommunications network (18), - interact with said interactive service server via the network of telecommunication (18). In the latter two cases, and in order to interact with the interactive service server, the computer program can, in particular, display a menu with several selectable options or an input area for searching among the information available on the server (15) interactive service. In practice, the ancillary terminal (16) comprises a microprocessor which, when it executes the steps of the computer program stored in a memory, is configured to: generate one or more information requests (RI) relating to a television program (E) being broadcast, sending, to the server (15) of the interactive service, the information request or requests (RI) generated, via the connection means to the telecommunications network (18). The information request (s) (RI) are generated automatically by the computer program or manually by the user, via a control means such as keys, touch screen, means of voice recognition, means of sign recognition, or other. In response to the one or more information requests (RI), the interactive service server (15) sends one or more information (1E) relating to a television program (E) to the additional terminal (16). broadcast, and consistent with the request. The ancillary terminal (16) then displays the information received. Returning to the previous example of the tennis match, the computer program generates the display of a menu with three selectable options: "statistics of player A", "statistics of player B", and "make a prognosis". If the user selects the "player A statistics" option, the accessory terminal (16) generates and then sends to the interactive service server (15) an information request (RI) relating to the player A's statistics. In response to this information request (RI), the server (15) of the interactive service sends, to the terminal (16), all the information (1E) that it holds relating to the statistics of the player A. The terminal appendix (16) then displays the statistics of the player A. In the particular case of a participative game, the additional terminal (16) can send to the server (15) of the interactive service a response information (IR). The computer program can, in particular, generate the display of a menu with several selectable responses or an input area for writing a response. The terminal (16) receives, first of all, a validation information (V) concerning a response to the interactive game offered by the interactive service. The validation information (V) is generated by the user via a control means of the type described above. Upon receipt of this validation information (V), the ancillary terminal (16) then generates a response information (IR). The latter contains, in the form of digital data, a response to the interactive game offered by the interactive service. These digital data may, for example, be a "Y response" data, one or more "Question X" and "Y response" data pairs, a "Y response" data pair, and "Response validation time". or any other data or couples of data suitable to those skilled in the art. The ancillary terminal (16) then sends, to the server (15) of the interactive service, the response information (IR) generated. The auxiliary terminal (16) comprises a microprocessor which, when executing the steps of a computer program stored in a memory, is configured to: - save in a digital file the answer selected or written by the user via the means of command, - send, the digital file, to the server (15) of the interactive service, via the connection means to the telecommunications network (18). Starting from the previous example of the tennis match, the user will first select the "make a prognosis" option. Following this selection, the computer program generates the display of a menu with two selectable answers "Player A winner" or "Player B winner". The user generates a validation information (V) by selecting the option "Player B winner". Upon receipt of this validation information (V), the ancillary terminal (16) generates and sends to the server (15) of the interactive service, a response information (IR) containing the answer "Player B winner". Upon receipt of this response information (IR), the server (15) of the interactive service records the answer "Player B winner" in its mass memory.

In the event that the ancillary terminal (16) receives a synchronization information (S) containing the allocated time slot (P), said auxiliary terminal -15- generates a response information (IR) only when it receives the information validation (V) concerning said response during said allocated time slot. Thus, in the example shown diagrammatically in FIG. 2, a response information is only generated for the first validation information (V), the second being generated outside the time slot (P). In practice, the ancillary terminal (16) comprises a microprocessor which, when executing the steps of a computer program stored in a memory, is configured to: extract the allocated time slot (P) contained in the synchronization information (S), typically the data "start time" and the data "end time", or the data "start time" and the data "duration", - record the validation time at which the validation information (V) is received, - check whether the validation time is contained in the allocated time slot (P), - if the validation time is contained in the allocated time slot (P), record in a digital file the answer selected or written by the user via the control means, - send the digital file to the server (15) of the interactive service via the connection means to the telecommunications network (18).

In general, when the participatory game comprises several successive questions, synchronization information (S) can be generated for each question independently.

The system which is the subject of the invention may also comprise several additional terminals (16, 17). For each of the ancillary terminals (16, 17), the method remains identical to that previously described. In particular, the transmission means sends the interactivity information (I), possibly the synchronization information (S) received by the digital receiver (13) 30 to the ancillary terminals (16, 17). Each ancillary terminal (16, 17) then connects independently to the interactive digital television service server (15) via the telecommunication network (18).
