Method and devices for controlling retransmissions in data streaming

In a method for the transmission of a plurality of data packets from a sender ( 1 ) to a receiver ( 2 ), the data transmission is performed over a link ( 5 ) with a transmission capacity having a limit. A presentation time is defined for a first data packet of said plurality, and the receiver ( 2 ) performs a first check whether data packets are correctly received. At least one data packet is selected for retransmission according to the result of the first check. In the method, a delay budget (DB) is determined from the presentation time of the first data packet. Furthermore, a delay requirement is determined for the retransmission of the selected data packet from the limit of the transmission capacity and from the transmission capacity required for the selected data packet. A comparison ( 30 ) of the delay requirement and the delay budget (DB) is performed, and the retransmission is executed for the selected data packet according to the result of the comparison ( 30 ). Devices and software programs for executing the method are also described.
