A digital video recorder connected to a DV camcorder sends, to the camcorder upon detecting camcorder mode change from a reproduction mode to a rewind mode, a stop command to forward a DV tape toward its end until a newest time code coincides with a time code at a reproduction end position. Thereafter, upon completion of the tape forwarding, and upon camcorder mode change from a reproduction mode to a stop mode, the recorder sends a reproduction command to, and receives a response from, the camcorder, and determines, based on the response, result of the reproduction by the reproduction command. If the recorder determines the result as successful, it determines reproduction of the tape to be interrupted, while if it determines the result as failing, it determines dubbing of DV stream from the tape to be completed. This prevents omission of dubbing of DV stream from the tape without fail.
