Abstract
Apparatus and method for packet redundancy and recovery are disclosed. In a transmitter, parity packets are generated by executing exclusive OR between the corresponding data packets, and are transmitted along with the data packets to a receiver. In the receiver, lost data packets are found out and are recovered by executing exclusive OR between the corresponding data packets and the corresponding parity packets. This invention enhances the reliability of streaming data transmission using loss-recovery packets. Data packets are grouped and transmitted with redundant packets to allow the receiver to recover a lost packet within the group. This will minimize the need and therefore the time and delay to request a retransmission of the damaged or lost packets.
