- the present invention relates to a video editing device for editing video information on a video information recording medium such as a magnetic tape, a magnetic disk, and an optical disk, and a video editing method.
- a video information recording medium such as a magnetic tape, a magnetic disk, and an optical disk
- Fig. 6 shows the system configuration of a conventional video editing device.
- the rotating drum device 600 scans the magnetic tape 610 serving as a recording medium, and the magnetic tape 610 already passes through the reproducing heads 601A and 601B. Read the recorded video signal.
- the insert processing means 603 detects a minimum unit break of data, for example, a frame break, and The video signal for the insert is output to the recording heads 604 A and 604 B from the break detected at the point of time.
- FIG. 3 is an explanatory diagram showing the phase relationship between the base data and the insert data when insert editing is performed on the correct base data.
- FIG. 4 is an explanatory diagram showing the phase relationship between the background data and the insert data when insert editing is performed on the background data having a discontinuous portion caused by a forced recording operation or the like.
- FIG. 5 is an explanatory diagram showing the phase relationship between the base data and the insert data when insert editing is performed on the base data whose data format changes on the way. If the underlying data is correct, as shown in FIG. 3, the underlying data 301 and the video signal 302 from the external device maintain the same phase, and the data delimiters always match. In this case, insert editing can be performed normally.
- the background data 401 and the video signal 402 from the external device will be out of phase, and will be created by insert editing.
- the data obtained will be irregular.
- the background data 501 and the video signal 502 from the external device are out of phase. In such cases, the edited data may appear correct to the user of the video editing device and is often overlooked until it becomes a serious problem. Disclosure of the invention
- the present invention has been made in view of such a conventional problem, and when incorrect data is generated on the background due to a user's own unconscious operation or the like, meaningless data is not used in insert editing. It is an object of the present invention to provide a video editing device and a video editing method that can issue a warning to perform editing and reduce troubles caused by the editing work.
- a video editing apparatus includes: an insert data reading unit for reading data to be inserted from outside; Input means for reading the background data read out, and insert data read by the insert data reading means and the base data read by the base data reading means, so that the base data is correct.
- Data checking means for comparing and collating the signal format including the data format with the data transmission rate, and checking whether or not the base data has the signal format of the insert data; and When the check result of the means indicates nonconformity, a warning display means for issuing a warning, an insert processing means for inserting data to be inserted into the background data, and a data output from the insert processing means, Edited data recording means for performing insert recording on the recording medium.
- the video editing method of the present invention is obtained by an insert data reading step of reading data to be inserted from the outside, a base data reading step of reading base data recorded on a recording medium, and the insert data reading step.
- Input the insert data and the base data obtained from the base data read data compare the base data with the signal format including the data transfer rate, and check if the base data is continuous correctly.
- FIG. 1 is a block diagram showing a basic configuration of a video editing device according to an embodiment of the present invention.
- FIG. 2 shows an image when a magnetic tape recording / reproducing device is used as the recording / reproducing system.
- FIG. 2 is a system block diagram illustrating a system configuration of the editing device.
- FIG. 3 is an explanatory diagram for explaining the phase relationship between the base data and the insert data when performing insert editing on correct base data.
- FIG. 4 is an explanatory diagram for explaining the phase relationship between background data and insert data when performing insert editing on discontinuous background data.
- FIG. 5 is an explanatory diagram for explaining the phase relationship between the base data and the insert data when insert editing is performed on the base data whose data format changes in the middle.
- FIG. 6 is a system block diagram showing the system configuration of a conventional video editing device. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 is a block diagram mainly showing a signal processing system of the video editing apparatus according to the present embodiment.
- background data reading means 101 reads background data to be inserted from a recording medium.
- the insert data reading means 102 reads data to be inserted from an external device.
- the insert processing means 103 inserts the data read from the insert data reading means 102 into the base data read from the base data reading means 101.
- the data checking means 105 is valid for the background data read from the background data reading means 101 before insert editing by the insert processing means 103, that is, the continuity of the data and the insertion data reading means. Check compatibility with data read from stage 102.
- the warning display means 106 gives a warning to the user when the data check means 105 determines that the underlying data is incorrect (nonconforming).
- FIG. 2 is a system block diagram of the video editing apparatus of the present embodiment using a magnetic tape recording / reproducing apparatus as an example of the recording / reproducing system.
- the video editing apparatus of the present embodiment includes a rotary drum device 200, an input section 202, and an insert processing means 103, similarly to the conventional apparatus shown in FIG. You.
- a data check unit 105 is provided between the input unit 202 and the insert processing unit 103.
- a warning display means 106 is provided for displaying “nonconforming” when the collation result of the data check means 105 is “nonconforming”.
- the reproducing heads 201A and 201B correspond to the background data reading means 101 in FIG. 1, and the input section 202 corresponds to the insert data reading means 102 in FIG. .
- the rotating drum device 200 scans the magnetic tape 210, reads the video signal via the reproducing heads 201A and 201B, inserts processing means 103 and data checking means 1 0 and the video signal.
- the insert processing unit 103 detects a minimum unit break of data and starts from the first detected break.
- the video signal for the insert is output to the recording heads 204A and 204B.
- the recording heads 204 A and 204 B record the input video signal on the magnetic tape 210.
- the data check means 105 checks whether the underlying data is correct before actually performing the insert edit, and if the underlying data is incorrect, the warning display means 106 is incompatible with the user. This is indicated by a display or warning sound. As described above, when performing insert editing on incorrect background data, it is necessary to warn the user that meaningless edited data has been created and to reduce confusion due to the editing work. Can be improved.
- the video editing apparatus of this embodiment uses a magnetic tape recording / reproducing apparatus, an optical disk recording / reproducing apparatus, a magneto-optical disk recording / reproducing apparatus, a magnetic disk recording / reproducing apparatus, a semiconductor recording / reproducing apparatus, or the like may be used. .
- the compatibility of background data is checked before performing insert processing, and when a background data is incompatible, a warning can be given to the user. . For this reason, it is possible to prevent unnecessary insert editing of video data overnight.
