Abstract: Method of formatting a stream of data for mobile terminals according to a series of frames which comply with the ATSC-MH standard or with a standard which is upward compatible with ATSC-MH, a frame comprising a predetermined number of slots, each slot being able to be allocated to the transport of data associated with a service, said method comprising a step of defining a slots allocation pattern making it possible to meet a total bitrate need required for the services for a set, called a super frame, grouping together M frames, M being greater than 1, consisting in: Allocating a minimum number N of slots for each frame of a super frame as a function of the total bitrate need and of the bitrate allocated to a slot, Allocating an additional slot in a predetermined number p of frames of a super frame, so as to comply with the total bitrate need with a minimum bitrate stepsize equal to the bitrate allocated to a slot.
