A system 7 for transmitting a target stream 7 r compliant with the Real Time Protocol or its equivalent. The target stream 7 r has time stamps according to its content and other fields including a sequence number. The system 7 comprises:-means for receiving the target stream 7 r from at least one source and a broadcasting stream ( 7 ae, 7 ve) from a broadcasting network, the broadcasting stream being compliant with MPEG-2 standard or its equivalent;-means ( 72,74,76,78 ) for packetizing or sectionalizing the broadcasting stream ( 7 ae, 7 ve) to form a packetized elementary stream ( 7 ap, 7 vp);-means ( 7 A) for encapsulating the target stream 7 r in a modified form of a stream of DSM-CC sections of MPEG-2 standard; and-means 7 M for multiplexing the stream of DSM-CC sections and the packetized elementary stream to form a transport stream TM compliant with MPEG-2 or its equivalent, the transport stream including transport stream packets into which the stream of DSM-CC sections and packetized elementary stream are divided and encapsulated, the transport stream packets each including a packet identifier for itself. |
