PROBLEM TO BE SOLVED: To improve a recovery rate of packets while efficiently utilizing optimum quantity of redundant information. SOLUTION: A Partially-Overlapped Block (POB) code as a new encoding system is disclosed in which a plurality of different block codes are combined so that they partially overlap one another. A decoding method is also disclosed corresponding to this encoding system. Further, a method is disclosed for recovering a plurality of packets using a loss correction capability of this code. According to this technique, recovery of the larger number of packets than the number of added redundant packets per frame can be possible by well reusing redundant information of neighboring frames without increasing the asymptotic calculation quantity of a decoding algorithm.
