Abstract
The invention relates to a method for transmitting over a data communication network data packets of a data stream to a receiving device, characterized in that it comprises the steps of: selecting a data packet from a buffer memory containing data packets to be transmitted (301, 401); determining whether the playout time of the selected data packet at the receiving device allows a recovery of said selected data packet (303, 410); assigning a first priority level or a second priority level to the selected data packet based on the result of the determining step (306, 307, 411, 413); and transmitting the selected data packet with said assigned first or second priority level (308, 408). The invention relates also to a software application and a transmitting device implementing the transmission method.
