Abstract:
1. A method of transmitting data packets comprising: identifying a priority of each packet of a plurality of packets to be transmitted; selectively transmitting higher priority packets before transmitting lower priority packets of the plurality of packets; receiving the transmitted packets; smoothing the received data packets; and playing-out the smoothed packets, wherein, the step of selectively transmitting is performed by calculating a probability of higher priority packets being delivered prior to play-out times for the higher priority packets and transmitting a packet only if this probability is greater than a set threshold and wherein calculating a probability of higher priority packets being delivered prior to play-out times for the higher priority packets is performed by estimating the success probability that a first data packet of the plurality of data packets will be delivered before the play-out time for the first data packet.
