In a recording device (1), a switching portion (19) is supplied with an ID signal from an identification signal generating portion (21) in a video display device (2) through a connector output portion (8). The switching portion (19) is also supplied with an ID signal outputted from an identification signal generating portion (15) in the recording device (1). When the ID signal indicating the video display device (2) is outputted from a return identification signal distinguishing portion (17) to a recording standby signal generating portion (18), the switching portion (19) is switched to the side-b so that the ID signal inputted to the recording device (1) is outputted to the outside as it is. The ID signal passed through the recording device (1) is inputted to an identification signal input portion (41) in an analog video signal output processing portion (4). When a recording standby ON signal is inputted from a recording standby switch (16) into the recording standby signal generating portion (18), the switching portion (19) is switched to the side-a independently of presence/absence of the signal input from the return identification signal distinguishing portion (17) so that the ID signal of the recording device (2) is outputted to the outside from the identification signal generating portion (15).
