A delivery data transmission device (100A) is mounted on a train, and transmits delivery data. A redundancy-degree decision unit (115A) decides a redundancy-degree of an erasure-correction code to be applied to delivery data when a distance between the delivery data transmission device (100A) and a next arrival station the train stops at next becomes equal to or smaller than a threshold value. An encoding unit (116B) encodes the delivery data at an encoding rate corresponding to the redundancy-degree decided by the redundancy-degree decision unit (115A).
