Abstract

A system 7 for transmitting a target stream 7r compliant with the Real Time Protocol or its equivalent. The target stream 7r has time stamps according to its content and other fields including a sequence number. The system 7 comprises:—means for receiving the target stream 7r from at least one source and a broadcasting stream (7ae, 7ve) 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 (7ae, 7ve) to form a packetized elementary stream (7ap, 7vp);—means (7A) for encapsulating the target stream 7r in a modified form of a stream of DSM-CC sections of MPEG-2 standard; and—means 7M 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.
