Method, device and software application for scheduling the transmission of data stream packets

A non-transitory computer-readable storage medium storing a software application for transmitting over a data communication network data packets of a data stream to a receiving device, the software application comprising:

• computer executable instructions for selecting a data packet from a buffer memory containing data packets to be transmitted;
• computer executable instructions for determining whether the play-out time of the selected data packet at the receiving device allows a recovery of said selected data packet;
• computer executable instructions for assigning a first priority level or a second priority level to the selected data packet based on the result of the determining step;
• and
• computer executable instructions for transmitting the selected data packet with said assigned first or second priority level.

A transmitting device for transmitting over a data communication network data packets of a data stream to a receiving device comprising:

• a selection unit for selecting a data packet from a buffer memory containing data packets to be transmitted;
• a determination unit for determining whether the play-out time of the selected data packet at the receiving device allows a recovery of said selected data packet;
• an assignment unit for assigning a first priority level or a second priority level to the selected data packet based on the result of the determination unit;
• and
• a transmission unit for transmitting the selected data packet with said assigned first or second priority level.
