Method for real-time data transmission in a communication network

A transmitter for a communication network for transmitting useful data to a plurality of receivers, the receivers being synchronized in terms of time via a synchronization method, the transmitter comprising:

• a control device configured and set up to transmit at least one useful data message by:
• stipulating at least one transmission time for transmitting a respective useful data message to the plurality of receivers stipulated during real-time data transmission;
• assigning each of the plurality of receivers to a respective receiver useful data area within the respective useful data message such that a respective receiver useful data area is assigned to a respective receiver of the plurality of receivers;
• and
• transmitting the useful data message to a first receiver of the plurality of the receivers at the at least one transmission time.

A receiver for a communication network for receiving useful data from a transmitter and for forwarding the useful data to a further receiver, the receiver and further receiver being synchronized in terms of time via a synchronization method, the receiver comprising:

• a control and memory device configured and set up to receive, process and forward at least one useful data message received from the transmitter by:
• assigning a receiver useful data area within a respective useful data message such that a respective receiver useful data area is assigned to the further receiver;
• storing the useful data contained in the receiver useful data area;
• and
• forwarding the useful data message to the further receiver at the at least one transmission time.
