Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic editing control device, in which when three points, an editing end point of a playback machine and an editing machine, and an editing start point of one of them are registered in a memory, a determining means determines which Based on the determination result, the first or second calculating means calculates and registers the editing start points of the remaining playback devices or editing devices, thereby starting the remaining editing operations. An object of the present invention is to provide an automatic editing control device that automatically registers points and has good operability.

3/4-inch U-standard video tape recorders have a high relative speed between the video head and the tape, have a wide video signal recording track width, and record with a video guard band, so they are faster than regular home videos. The image quality is high. Further, the U standard video tape recorder has a rotary erase head, a blanking switch, and also has a capstan servo and reel servo system. For this reason, assembly editing is performed in which each cut is temporarily recorded in a tape cassette in random order, and then a desired cut is selected from this recorded tape cassette, played back, and recorded in order in the master tape cassette, which becomes the recorded master. Editing such as insert editing in which a reproduced signal from a recorded tape cassette is recorded at an intermediate position of the tape cassette can be performed with high image quality and high precision.

Conventionally, the video tape recorder that plays the recorded cassette tape and the video tape recorder that edits and records the master cassette tape are controlled remotely, and the editing positions of the recorded cassette tape and the master cassette tape are selected and registered. ,
There is an automatic editing control device that automatically edits and records a reproduction signal at a registered position on a master cassette tape at a registered position on a recorded cassette tape.

In this conventional automatic editing control device, editing cannot be executed unless at least the editing start points of each of the playback machine and the editing machine are registered. However, in actual editing work, for example when editing the cut up to the moment the ball hits the bat in baseball, or the cut up to the moment the home run ball enters the stands, the editing end point has an important meaning, and compared to this, the editing end point has an important meaning. In some cases, the editing starting point does not have such important meaning. In such cases, with conventional devices, the user has to calculate backwards the editing start point from the editing end point and the time required for editing (cut length) and register this editing start point, which has the disadvantage of poor operability. It was hot.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

FIG. 1 shows an overall configuration diagram of the apparatus of the present invention. In the figure, a memory 33 is used to write and register the values of the editing start point and editing end point of each of the playback device and the editing device. When three points, the editing end point of each of the playback machine and the editing machine and the editing start point of either the playback machine or the editing machine, are registered in this memory 33, the editing start point registered by the determining means A is reproduced. It is determined whether it is a machine or an editing machine. Here, when it is determined that the editing start point of the playback device is registered, the memory 33 is
