Abstract: System and method for multiplexing data Di and one or more streams containing video data Dvideo in a transmission channel with fixed bitrate comprising a multiplexer (11) and its controller (112), the multiplexer (11) comprising one to n inputs (11v) receiving the stream or streams Dvideo, a bitrate allocator (12), the multiplexer (11) comprises an input (11d) for the data Di to be multiplexed, and the said system comprises at least the following elements: a memory (20) receiving the data to be multiplexed with the stream or streams Dvideo, a bitrate estimator (21) which transmits a bitrate request Rd to the bitrate allocator (12), the bitrate request Rd is transmitted to the controller (112) of the multiplexer and delayed, the controller (112) is suitable for reading from the memory (20) the data Di to be multiplexed, up to compliance with the bitrate request Rd.

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.
