A bit rate converting apparatus, which has no function of rewriting PCR values and is suitable for DVB-H signals, comprises a means (42) that stores DVB-H signals according to a first bit rate; a means (46) that successively generates NULL packets according to a second bit rate; and a means (45) that outputs either the stored packets or the NULL packets according to the second bit rate. The apparatus may further comprise a means (51) that receives the TS signals of DVB-H standard and that removes the NULL packets from the TS signals. Alternatively, the apparatus may further comprise a means (61) that receives the TS signals of DVB-H standard and that passes only PSI/SI packets and packets constituting the TS signals and representative of a program.
La présente invention concerne un appareil de conversion du débit binaire, ne possédant pas de fonction de réécriture des valeurs PCR et qui convient pour les signaux DVB-H. Il comprend un moyen (42) qui stocke des signaux DVB-H en fonction d'un premier débit binaire, un moyen (46) qui génère successivement des paquets NULL en fonction d'un second débit binaire et un moyen (45) qui produit les paquets stockés ou les paquets NULL en fonction du second débit binaire. L'appareil peut aussi comprendre un moyen (51) qui reçoit les signaux TS de la norme DVB-H et supprime les paquets NULL des signaux TS. Dans une variante, l'appareil peut aussi comprendre un moyen (61) qui reçoit les signaux TS de la norme DVB-H et ne laisse passer que les paquets PSI/SI et les paquets constituant les signaux TS et représentatifs d'un programme.
