Abstract:
1. A video recorder to be connected to a DV (Digital Video) camcorder via an IEEE (Institute of Electrical & Electronics Engineers) 1394 serial bus, the video recorder comprising: an operation means for commanding and operating the DV camcorder and the video recorder itself; an IEEE 1394 interface for sending and receiving control commands and its response signal, and also sending and receiving stream data, to and from the DV camcorder; a video recording means for recording, on a recording medium, stream data received from the DV camcorder via the IEEE 1394 interface; a time code acquisition means for acquiring a time code contained in data which is in stream data recorded on a DV tape of the DV camcorder, and which corresponds to each reproduction position in the DV tape; a time code storage means for storing time codes contained in data which are in the stream data recorded on the DV tape, and which respectively correspond to a dubbing start position and a dubbing end position in the DV tape commanded by the user (such time codes being hereafter referred to as “start time code” and “end time code”, respectively), wherein the time code acquisition means acquires the start time code and the end time code when a user, using the operation means, commands the dubbing start position and the dubbing end position in the DV tape after the user, using the operation means, commands the DV camcorder to perform normal reproduction or fast-forward reproduction of the stream data in the DV tape in the DV camcorder; a program dubbing control means for controlling the DV camcorder to rewind the DV tape upon completion of the storage of the start time code and the end time code by the time code storage means when the user, using the operation means, commands program dubbing of stream data in the DV tape, and further for controlling the DV camcorder to reproduce and send stream data in a data area from data containing the start time code to data containing the end time code in the DV tape upon detection of ending of the rewinding of the DV tape, and still further for receiving the thus reproduced and sent stream data from the DV camcorder via the IEEE 1394 interface so as to allow the video recording means to record the thus received stream data on the recording medium; and a reset information storage means for storing information on data with a time code being reset in the DV tape (such information being hereafter referred to as “reset information”), wherein when the time code acquisition means acquires the same time code as the end time code stored in the time code storage means during the reproduction in which the program dubbing control means controls the DV camcorder to reproduce and send the stream data in the data area from the data containing the start time code to the data containing the end time code in the DV tape, the program dubbing control means determines, on the basis of the reset information stored in the reset information storage means, whether or not the reproduction position, at the time of acquiring the same time code as the end time code, is the same as the dubbing end position commanded by the user using the operation means, and further stops the DV camcorder and the video recording means if the program dubbing control means determines that the then reproduction position is the same as the commanded dubbing end position.
