Communication system, transmitting device and receiving device

A communication system in which a transmitting device and at least one receiving device are connected to each other,

• wherein the transmitting device includes
• a packet generator that generates k (k:
• an integer of 2 or more) number of data packets as transmission targets,
• a coder that generates n (>k) number of coded packets by coding the k number of generated data packets,
• a transmission controller that instructs that the coded packets are to be transmitted or the transmission of the coded packets is to be interrupted, and
• a first transmitter that sequentially transmits the generated coded packets in response to a transmission instruction from the transmission controller,
• the receiving device includes
• a receiver that receives the transmitted coded packets,
• a decoder that decodes the received coded packets, and
• a second transmitter that transmits a transmission interruption request packet for requesting transmission interruption of the coded packets to the transmitting device in a case where a first condition in which the coded packets are not able to be decoded in the decoder is satisfied, and
• the transmission controller causes the first transmitter to interrupt the transmission of the coded packets in response to the transmission interruption request packet.
