Abstract: To provide a reception device capable of precisely estimating throughput on the basis of a breakpoint between video frames in a communication system where video-frame-based transmission is intermittently performed. A reception device is configured to be provided with a reception means, a breakpoint position estimation means, and a transmission means. The reception means receives packets obtained by dividing a video frame. The breakpoint position estimation means estimates a packet which is a breakpoint between video frames on the basis of packet information about the packets received by the reception means. The transmission means transmits, to a transmission device of the packets, information about the reception time of the video frame and information about the data size thereof on the basis of the estimation result of the breakpoint.
