PROBLEM TO BE SOLVED: To solve the problem that optimum processing can not be judged when it is not judged whether a recorder is now reproducing an image on a controller even though different types of processing are performed with respect to the same input instruction between when the recorder is now reproducing the image and when the recorder is not reproducing the image in normal processing. SOLUTION: In an input instruction detection step 201, whether an instruction to be inputted is a fast feeding instruction or a fast backward feeding instruction is detected, in a synchronous packet detection step 202, whether a synchronous packet transmitting the current video/audio data, etc., is transmitted from a digital video camera is detected in the case of corresponding to the instructions, in a control signal selection step 203, a control signal for increasing reproduction speed is selected during reproduction in the case of detecting that video/audio data are received from the digital video camera, in the control signal selection step 203, a control signal for performing fast scanning is selected without performing reproduction in the case of detecting that the video/audio data are not received, and in a control signal transmission step 204, the control signal is transmitted to the digital camera.
