The information to be described may be changed in accordance with the specifications of the multimedia optical disk to be created by the data processing device. The scenario information is expressed in a format other than the text format. For example, scene information of each scene is stored in a folder on the computer one by one, and one folder corresponds to one scene. May be expressed in a format that expresses the scenario information that is the content structure in the entire folder tree.

(Creation of Scenario Information) Next, creation of scenario information of the data processing apparatus will be described. In the present data processing apparatus, prior to the creation of a multimedia optical disk, the above-described scenario information is created from a video image recorded on a video tape as a material. The process of creating scenario information is performed by the data processing device main body 1 reading the scenario information generation program 21 from the hard disk 13 and executing the program.

In creating the scenario information, first, a process of detecting a cut point of a video tape video as a video video material is performed. The cut point is a point where the shooting date and time of the video recorded on the video tape becomes discontinuous, and is the same content video in which a video section from the cut point to the cut point is continuously captured.

In the cut point detection processing, the data processing apparatus main body 1 uses the IEEE 1394 interface 15 to
The V deck 5 is controlled to start the reproduction of the video tape. FIG. 15 shows shooting information 1 recorded on a video tape.
301 and the shooting information 1301 includes a shooting date 1302
The date and time of shooting, the shooting time 1303, the shooting hour, minute, and second, and the time code 1304, the shooting hour, minute, and second, and the number of frames are included. The data processing device body 1 is IEEE
The photographing information 1301 recorded on the video tape is sequentially taken in via the 1394 interface 15. First, shooting information 1301 of the video at the beginning of the video tape is stored as IN point information 1402, which is the start position of the video. The data processing apparatus body 1 continuously captures the photographing information 1301 recorded on the video tape, compares the photographing date 1302 and the photographing time 1303 of the captured photographing information 1301 with the immediately preceding photographing information 1301, and compares the photographing date 1302 with the photographing date 1302. If any of the times 1303 is discontinuous, it is regarded as a video break. When a break in the video is detected, the photographing information 13 captured from the position where the break was detected.
01 as the OUT point information 1403 as the end position.
The cut point information 1401 shown in FIG. 15 is combined with the N point information 1402, and the cut point information 1401 is sequentially recorded in the cut point information file 20 on the hard disk 13 as shown in FIG. Then, the photographic information 1301 of the video immediately after the position of the break is taken in, stored as the next IN point information 1402, and the detection of the break information is repeated. There is no image behind the position where the cut was made,
If the shooting information 1301 cannot be captured, the cut point detection processing ends.
