JPH043384A - Editing controller for video tape recorder - Google Patents

Abstract

PURPOSE:To obtain an editing controller which controls editing like film editing by recording and holding a video signal for a certain time and always simultaneously monitoring pictures preceding and following the current picture. CONSTITUTION:The picture of a VTR source input to which an editing point should be set is read out from a video signal storage part 5 by a control part 1 and several frames are simultaneously displayed on a display part 2 in the same manner as a movide film. In this case, the picture in the center of the display screen corresponds to the input of the source VTR in 1:1, and the editing point is set there. A storage video time T(n) and a time code TC(n) are stored in relations of 1:1, and for example, TC(n-1) is a dummy actual time, and the picture is changed to change the dummy actual time. Consequently, an editor can set the editing point without paying his attention to the time code while relating preceding and following pictures to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a VTR editing control device having an internal video storage section and means for effectively editing video recorded on a video tape recorder (hereinafter referred to as VTR). It is something.

The ideal conventional technique for video editing is film editing, where past, present, and future video can be viewed simultaneously.

Conventionally, when editing magnetically recorded video signals, an indirect method is used in which an absolute address called a time code is given to each video signal, and editing is performed by specifying and processing this address.

The configuration will be described below with reference to FIGS. 3 and 4.

FIG. 3 shows an external view of the VTR editing control device.

In FIG. 3, the VTR 1i collection control device is composed of a data display display 11 and an editing control device main body 12 other than the display section. and a recorder 15 are connected.

FIG. 4 is a block diagram showing the internal configuration of the VTR editing control device. In FIG. 4, the VTR editing control device consists of a control section 16, a display section 17 connected to the control section 16, an input interface 18, and an external control interface 19, and a control object connected to the external control interface 19. The control unit 16 controls the VTR source using a time code, which is an absolute address signal of a video signal superimposed on the VTR source. In addition, the actual video at that time can be checked by directly monitoring the Jπ source output on the source VTR, or by displaying only the superimposed time code on the data display display 11.

Problems to be Solved by the Invention With conventional editing control devices, when determining the optimum point of an actual image, the target image is observed simultaneously with the previous and subsequent images, and the relationship between the previous and subsequent images is determined. It was difficult to identify, relate and edit.

The present invention solves the above problems, and aims to provide an editing control device that is similar to film editing.

Means for Solving the Problems In order to solve the above problems, the VTR editing control device of the present invention includes: a recording section that can record and hold video signals for a certain period of time; a display section that displays stored video and data; A control unit that operates to simultaneously handle future images, current images, and past images by delaying real time by a certain period of time and handling the images and data, and displaying these simultaneously on the display unit. It is equipped with the following.

Effect: With the above-described configuration, the control unit can freely set the timing of reading from the storage unit, and the video storage signal of period T (n) can be delayed by T (i) in consideration of the time when it can actually be handled. This allows the real time to be pseudo-represented as T(n-i), and the video storage signals before and after that time are read out and displayed on the display at the same time, making it possible to perform editing that associates past, present, and future video signals at the same time. It is said that

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the internal configuration of a VTR editing control device according to an embodiment of the present invention. In FIG. 1, 1 is a control unit, 2 is a display unit, 3 is an input interface, and 4 is an external control interface, which operate almost the same as in the conventional case, but the display unit 2 not only displays data, but also displays data.
Video signals are also displayed simultaneously on one screen. 5 is the control unit 1
This is a video signal storage section controlled by the VTR source input, and can store several tens of frames of VTR source input. Reference numeral 6 denotes an input switching section, which switches the VTR source input and inputs it to the video signal storage section 5.

Next, its operation will be explained. In the display section 2, an image input from a VTR source for which an editing point is to be set is read out from the video signal storage section 5 by the control section 1 and displayed in several frames at the same time in the same way as an i-film. During this display, the image at the center of the display screen has a one-to-one correspondence with the source VTR, and this point becomes the editing point. The stored video period T(n) and the time code TC(n) are stored in a one-to-one relationship, as shown in FIG. By changing this, the pseudo real time can be changed. This allows editors to set editing points while relating the previous and subsequent screens without being aware of the time code.

Also, when changing the VTR source for setting the editing point, the input switching section 6 inputs the desired VTR source,
After the FF and /REW operations, the editor determines the editing points to some extent, so when the VTR enters normal playback mode, several tens of frame images are automatically captured and stored in the video signal storage section 5, and the above-mentioned The action is repeated.

In this way, during work, when settings are changed in response to input from the keyboard or dial, or when FF/REW operations are performed, the video signal and time code in the video signal storage section 5 are updated. Moreover, by changing the pseudo-real time, the editor can relate the previous and subsequent screens of several frames, allowing the editor to work with past, present, and future footage at the same time.

Effects of the Invention As described above, according to the present invention, since it is possible to simultaneously monitor the images before and after the image being handled at any time, the appropriate point for editing can be quickly determined, and an editing environment can be created efficiently. be able to.
