Abstract
A loss correction encoding device having an improved capability of loss correction using LDPC-CC is disclosed. In the loss correction encoding device (120), a rearranging unit (122) rearranges information data contained in n information packets according to the constraint length Kmax and the encoding rate (q−1)/q of a cheek polynomial of the loss correction code used in a loss correction encoding unit (123). Specifically, the rearranging unit (122) rearranges the information data in such a way that continuous Kmax×(q−1) pieces of information data after rearrangement are contained in different information packets. The rearranging unit (122) distributes the information data to information blocks from n information packets (n satisfies formula (1)).Kmax×(q−1)≦n (1).
