PROBLEM TO BE SOLVED: To control a redundancy and a delay time without increasing a circuit scale or software code quantity when a stream speed and network quality are different.;SOLUTION: In an error correction encoding device, an information packet being the target of an error correction encoding arithmetic operation is divided into information packet elements, and a matrix where the information packet elements are defined as line elements only by the predetermined number of lines is generated, and the error correction encoding arithmetic operation is repeatedly performed only by the number of columns in the column direction of the matrix, and test packet elements are generated, and at least one information packet is generated by using the information packet elements, and at least one test packet is generated by using the test packet elements, and the information packet and the test packet are separately transmitted.;COPYRIGHT: (C)2005,JPO&NCIPI
