Abstract: PURPOSE: A method of encoding and decoding dispersed source is provided to improve error correction capability of newly comprised LDPC code. CONSTITUTION: A dispersed source coding apparatus (1300) comprises: an encoder (1310), a transmitter (1320), a syndrome divider (1330), and a source opening unit (1340). The encoder encodes the second information, and produces compression syndrome of the first information based on the first information or parity check matrix of low density parity check (LDPC) code. The transmitter transmits the encoded second information or compression syndrome of the first information to a decoding apparatus. The syndrome divider partitions and transfers the compression syndrome in case of receiving feedback information of reconstitution failure under number k which is set in advance. The source opening unit transfers specific bit of the first information to the decoding apparatus in case of receiving feedback information of reconstitution failure over the number k.
