ABSTRACT:
A Partially-Overlapped Block (POB) code used in an encoding and decoding method in which a plurality of different block codes are combined so that the block codes partially overlap one another. A method for recovering a plurality of packets by using a loss correction capability of this encoding method in which a larger number of packets than the number of added redundant packets per frame are recovered, by reusing redundant information of neighboring frames effectively, without increasing the asymptotic complexity of its decoding algorithm.
