The present invention provides a reception device capable of being processed in real time with the scalable encoding characteristics even though the stream type data is transmitted by a TCP. The reception device comprises a frame detection unit (85) which detects the base layer reception completion time that a base layer of an object being replayed is equipped by a transmission image packet received in a reception unit (81) and a timer unit (86) which notifies the elapse of a timeout period to a reception completion processing unit (84) in case where the predetermined timeout period elapses from the time that the base layer of the object being replayed is equipped in the frame detection unit (85), wherein if the timer unit (86) notifies the elapse of the timeout period to the reception completion processing unit (84), a reception completion packet for the unreceived transmission image packet is transmitted to a transmission device (101).
