Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an editing device for editing a recording medium on which video and audio are recorded.

BACKGROUND OF THE INVENTION Editing is essential to creating a complete medium of video and audio. In the following, a method for synthesizing and editing a plurality of signals existing serially in the same medium in time will be explained.

Figure 2 shows the original recording medium 1a on which conventional video and audio are recorded.
The block diagram of the editing device of FIG. In the example shown in the figure, when the playback devices 2a and 2b of the original recording medium 11 are unable to play back recordings from two or several places at the same time, editing involves synthesizing video and audio from two or several scenes (for example, overlapping two screens). , when the video and audio to be synthesized are recorded on the same recording medium 1a, create one or more copies 1b equivalent to the recording medium 11 & on which the video and audio are recorded before editing. , equipment equivalent to the playback devices 2a and 2b is prepared and reproduced as many as necessary for editing to add and add video and audio from the original recording medium 1a and the plurality of them 1b to 1n, and the reproduced video and audio are reproduced. Synthesizer 3
Synthesis is performed by These controls are still performed by the editing control device 4.

Problems to be Solved by the Invention However, in the conventional apparatus described above, it is necessary to create copies 1b to 1n equivalent to the recording medium 11L on which video and audio are recorded before editing. Therefore, the problems that arise at this time are: firstly, the deterioration of video and audio that occurs when creating the copy 1b from the recording medium 11L, and secondly,
There is a need to create a copy 1b from the original.

The present invention solves the above-mentioned conventional problems, and is an editing device that can suppress deterioration of video and audio during editing that combines video and audio recorded on the same recording medium, and can perform editing with efficient working time. The purpose is to provide

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention is directed to combining and editing a plurality of signals existing serially in the same original recording medium in accordance with instructions from an editing control device. At least one of the signals is stored in a temporary storage medium, and the reproduction timing of the other signal and the signal stored in the temporary storage medium is controlled.

The configuration is such that a composite connection is performed by a composite unit.

Effects of the present invention By using the method described above, it is possible to suppress deterioration of images and sounds during editing in which images and sounds recorded on the same recording medium are combined, and to perform editing with efficient working time.

Embodiment Hereinafter, an editing apparatus according to an embodiment of the present invention will be described with reference to the drawings, taking a video tape recorder (hereinafter abbreviated as VTR) editing apparatus as an example.

FIG. 1 is a block diagram of a VTR editing apparatus according to an embodiment of the present invention. As shown in the figure, the magnetic recording medium, which is the original recording medium on which the original video and audio signals are recorded, is used as a reproducing device.
The reproduced video signal is input to a video synthesizer 9, and the audio signal is input to an audio synthesizer 10. The video synthesis section @9 and the audio synthesis device 10 record (accumulate) the signals reproduced by the VTR playback device 8 in the semiconductor recording section 11.12, which is a built-in temporary recording medium, and the synthesis section 13.
14, the signal reproduced by the VTR reproduction device 8 and the signal reproduced from the semiconductor recording section 11.12 are combined. The video signal and audio signal synthesized by the video synthesis device 9 and the audio synthesis device 10 are recorded on a magnetic recording medium 16, which is a recording medium, by a VTR recording device 16, which is a recording device. A VTR playback device 8, a video synthesis device 9, an audio synthesis device 10, and a VTR recording device 16 constitute a VTR editing control device 1, which is an editing control device.
7. Note that the semiconductor recording units 11 and 12 used have performance that causes less deterioration of the original signal than when using magnetic recording media, and a recording time that is sufficient for editing to synthesize video and audio. The control method for the editing device configured as described above will be explained below.

First, the VTR editing control device 17 controls the VTR playback device 8.
The video and audio recorded on the magnetic recording medium 7 are selected for editing. Next, when you start editing, VT
The R editing control device 17 first automatically reproduces the magnetic recording medium 7 and records either the video or the audio to be synthesized in the semiconductor recording section 11.12 only when performing editing that involves synthesis. Furthermore, the magnetic recording medium 7 is reproduced again, and the video and audio to be synthesized on the other side are combined with the video and audio recorded in the semiconductor recording sections 11 and 12. The synthesized video and audio are recorded on a magnetic recording medium 16 by a VTR recording device 16. Further, when performing editing without compositing, the VTR editing control device 17 performs editing using a conventional method that does not use the semiconductor recording sections 11 and 12. In this case, the selection of the editing location and the timing of synthesis are performed using the time code recorded on the original line body or by measuring the control signal with an internal counter.

As described above, according to this embodiment, the semiconductor recording sections 11 and 12, which are temporary recording media, are provided, and the VTR editing control device 17
By automatically controlling the system, it is possible to suppress characteristic deterioration during editing in which video and audio recorded on the same recording medium are combined, and to make editing more efficient in working time.

Note that although the above was explained using the example of a VTR, optical discs,
Needless to say, the present invention can also be applied to editing of magneto-optical disks and audio-only recording devices.

In addition, although the explanation has been made with one set of semiconductor recording units 11 and 12, which are temporary recording media, if multiple sets are provided, more complex editing is possible, and it is also possible to edit the outputs of only temporary recording media. It is something.

Note that the same function can be achieved even if the semiconductor recording units 11 and 12 are replaced with, for example, a magnetic recording medium and a VTR recording/reproducing device, but in this case, from the intended purpose, the replacement recording medium and VTR recording The playback device must be of a higher grade than the original recording medium and the VTR recording and playback device that plays the original recording medium and records the composite recording.

Effects of the Invention As is clear from the above embodiments, according to the present invention, it is possible to suppress characteristic deterioration during editing in which video and audio recorded on the same recording medium are combined, and to perform editing with efficient working time. We can provide an editing device that can.
