ABSTRACT:
In a method for the transmission of data packets (D) from a transmitter (TR) to a receiver (RE) identification of transmitted data packets are stored. Defective data packets (D) are detected by the receiver (RE), status messages (S) which request defective data packets for retransmission are sent from the receiver (RE) to the transmitter (TR) and retransmissions of requested data packets are performed according to the status messages (S). The transmitter (TR) evaluates a first status message (S11) with an identification of at least one first requested data packet and retransmits the first data packet. The transmitter (TR) then initializes a timing unit according to the retransmission of the first data packet, wherein the timing unit or a threshold for the timing unit is attributable to the first data packet. When the transmitter evaluates a further status message (S12) and detects at least one further data packet that is requested for a retransmission, it selects the further data packet if the timing unit has reached the threshold or if the identification of the further data packet is different from the identification of the first data packets. Only the selected data packets are retransmitted. A transmitter and software programs embodying the invention are also described.
