The invention relates to a system for organising fast data links using means designed for other data transmission methods. According to the invention, data intended for a given receiver (9) is transmitted from a given transmitter (13) as packets (6, 8) consistent with a network protocol over a data network (11) to a transmitting station (14), which multiplexes the packets into a digital transport stream (1) generated by it, marking those parts (2) of the transport stream that relate to said packets with a part (3) of the address of the receiver. The network protocol is preferably the TCP/IP protocol and the transport stream is preferably an MPEG system transport stream. The TCP/IP address of the receiving device (9) is dynamically allocated for this purpose from the address server (12) of the network, so the address is a temporary one and becomes available for reuse as soon as the transmission has been completed. Preferably the TS packets (2) in the MPEG system transport stream (1) that contain data intended for a given receiver are marked by setting their PID identifier (3) to be equal to 13 low-order bits of the temporary TCP/IP address of the receiver.
