Abstract
A method for selectively retransmitting packets is disclosed. The method includes categorizing groups of packets in an order of importance. The order of importance is based on a scope of adverse impact that a loss of a particular group has on a quality of reconstructed original information. The method also includes selecting a subset of the groups of packets to be retransmitted. The selection is based on network condition parameters. The method further includes requesting retransmission of the subset of the groups of packets when a buffer occupancy condition is met.
