A method for receiving a broadcast message in radio frequency and distributed over several frames, each frame having a predefined size and comprising three distinct sections (S1, S2, S3), namely: - a first section, - a second section allocated to a useful part, and - a third section allocated to an authentication message, a signalling message for reading the useful part of the frames to reconstitute the broadcast message, the signalling message being a set of information for reading the useful part of the frames to reconstitute the broadcast message, the signalling message being a set of parts of the signalling message, the number of parts of the signalling message being lower than the number of frames on which the broadcast message is distributed, the set of parts of the signalling message being in the initial frames so that the signalling message can be reconstructed from these initial frames, the set of information of the signalling message also allowing the part of the signalling message sent in each frame to be predicted, the first section being allocated to signalling data, signalling data being a function (g) of a part of the signalling message, the process comprising at least one step of: - reception of initial frames to obtain signalling data, - reconstitution of the signalling message from the initial frames, - prediction of the number of frames to be received to reconstitute the broadcast message and the portion of the signalling message in each frame to be received, - reception of new frames, and - for each new frame received, verification of the content of the first section of the new frame using the planned part of the signalling message. each frame having a predefined size and comprising three distinct sections (S1, S2, S3), namely: - a first section, - a second section allocated to a useful part, and - a third section allocated to an authentication message, - a first section, - a second section allocated to a useful part, and - a third section allocated to an authentication message, a signalling message for reading the useful part of the frames to reconstitute the broadcast message, the signalling message being a set of information for reading the useful part of the frames to reconstitute the broadcast message, the signalling message being a set of parts of the signalling message, the number of parts of the signalling message being lower than the number of frames on which the broadcast message is distributed, the set of parts of the signalling message being in the initial frames so that the signalling message can be reconstructed from these initial frames, the set of information of the signalling message also allowing the part of the signalling message sent in each frame to be predicted, the first section being allocated to signalling data, signalling data being a function (g) of a part of the signalling message, the process comprising at least one step of: - reception of initial frames to obtain signalling data, - reconstitution of the signalling message from the initial frames, - prediction of the number of frames to be received to reconstitute the broadcast message and the portion of the signalling message in each frame to be received, - reception of new frames, and - for each new frame received, verification of the content of the first section of the new frame using the planned part of the signalling message. - reception of initial frames to obtain signalling data, - reconstitution of the signalling message from the initial frames, - prediction of the number of frames to be received to reconstitute the broadcast message and the portion of the signalling message in each frame to be received, - reception of new frames, and - for each new frame received, verification of the content of the first section of the new frame using the planned part of the signalling message.
