Abstract

L'invention concerne un procédé d'insertion d'un fichier numérique, comprenant au moins un ensemble de données numériques (E ) comprenant un premier nombre de bits (Nb (E ) ) , dans un flux de transport (TS) de données multimédias en contexte de diffusion multimédia numérique (DMB), comprenant les étapes de détection (120), dans au moins un paquet de transport (TS ) appartenant audit flux de transport de données multimédias (TS), d'une redondance de bits, de détermination (130) d'un deuxième nombre (Nb (TS ) ) , de bits d' occurrences de ladite redondance dans le paquet de transport (TS ), de comparaison (160) du premier nombre de bits (Nb (E ) ) avec le deuxième nombre de bits (Nb (TS )) et, si le premier nombre de bits est inférieur ou égal au deuxième nombre de bits, de suppression (170), parmi lesdites occurrences de redondance, des bits en nombre correspondant au premier nombre et d' insertion (180) dudit ensemble (E ) de données numériques dans ledit paquet de transport (TS ). L'invention concerne aussi le procédé de réception (200) correspondant, ainsi que les dispositifs (10,1,2).The invention relates to a method for inserting a digital file, comprising at least one set of digital data (E) comprising a first number of bits (Nb (E)), in a transport stream (TS) of multimedia data. in the context of digital multimedia broadcasting (DMB), comprising the steps of detecting (120), in at least one transport packet (TS) belonging to said multimedia data transport stream (TS), of a bit redundancy, of determining (130) of a second number (Nb (TS)), of bits of occurrences of said redundancy in the transport packet (TS), of comparison (160) of the first number of bits (Nb (E)) with the second number of bits (Nb (TS)) and, if the first number of bits is less than or equal to the second number of bits, deletion (170), from among said occurrences of redundancy, numbered bits corresponding to the first number and d inserting (180) said set (E) of digital data into said transport packet (TS). The invention also relates to the corresponding reception method (200), as well as to the devices (10,1,2).
