摘要: The present subject-matter relates to transmitting a real-time data stream, namely simultaneously to multiple receivers over unreliable networks (e.g. wireless multicast), in a timely and reliable manner, in particular to a method, apparatus and computer program product for feedback-based real-time network coding. It is disclosed a computer-implemented method for a transmitting node, a receiving node, and an intermediate node of feedback-based real-time network coding from a transmitter and to one or more receivers, in particular comprising a linear combination of packets from the transmitter; determining whether the received linear combination of packets is linearly independent of previous linear combinations of packets; determining the validity of a priority level of the packets; determining validity of the deadline of the packets; determining whether a packet is to be removed from a transmit queue, and if determined removing it. There are also disclosed said transmitting, receiving, and intermediate nodes.
