To provide a transmission server that enables data retransmission in response to a retransmission request from a reception side by using communication after efficiently combining with an error correction code used in digital broadcasting, a transmission device and a reception device for digital broadcasting, and a program.SOLUTION: A transmission server 6 of the present invention inputs coded data of an error correction code related to digital broadcast generated by a transmission device 2 (3) and stores it for a predetermined time, receives a retransmission request packet generated when a bit error of the coded data cannot be corrected using the error correction code by a reception device 5 via an IP network 8, and forms and transmits an IP packet of coded data related to a retransmission request in response to the received retransmission request packet to the reception device 5. The transmission device 2 (3) of the present invention sequentially outputs the coded data to the transmission server 6. The reception device 5 of the present invention complements the coded data obtained through the retransmission request and repeats the retransmission request until the coded data is decoded.SELECTED DRAWING: Figure 1
