Abstract

PURPOSE:To shorten time required for the execution of preview by allowing both a reproducing side VTR and a recording side VTR to rapidly travel a tape when the recording side VTR reproduces a part of an edition specifying section if the edition specifying section is more than a prescribed length. CONSTITUTION:When the tape edition specifying section is more than the prescribed length and a part of the section is reproduced by the recording side VTR 5 in a preview mode, both the reproducing side VTR 4 and recording side VTR 5 execute the rapid traveling of the tape. Namely, a short edition specifying section and a long edition specifying section are prepared in the preview mode as a preconfirmation of VTR editing execution, and in the case of the long one, the recording side VTR 5 rapidly reproduces a part of the edition specifying section. At that time, the reproducing side VTR 4 is also set up to a rapid reproducing mode. Only in the vicinity of an edition start point and an end point, a normally reproduced video signal is outputted, so that the execution time of preview can be shortened.

Description

[Detailed description of the invention]

[Industrial Field of Application J] The present invention relates to an editing system equipped with a so-called preview code as one of its editing functions. 1. Prior Art Conventionally, a preview mode as a pre-confirmation of the status of an m-set in editing a VTR is performed in a procedure as shown in FIG. That is, the editing start and end points (specified sections) are inputted from the keyboard for the reproducing VTR and the recording VTR, respectively, and are stored in the RAM of the processor. When preview execution is commanded in this state, both the recording and playback VTRs
moves the tape to a predetermined position (pre-roll) (54
1) Both VTRs are in a pause state at the pre-roll position, and from that state first drive the playback side and recording side VTRs for playback (S42), and then set the monitor changeover switch to the recording side to output the output signal from the recording side VTR. Enter the number into the monitor (543), then the playback side. When the recording side VTR reaches the editing start point, change the monitor changeover switch, manually input the output of the playback side VTR to the monitor (544), drive the playback in this state until the end point of the m collection (S45), and end the editing. After this point, switch the monitor changeover switch and input the output of the recording side VTR to the monitor (546), and after the predetermined time elapses,
The playback side and recording side VTR are stopped (547), and the preview operation is ended.

[Problem to be solved by the invention]

However, in the above conventional example, even if the insert specified section is long, in the preview mode for checking before executing the VTRWA collection, everything from the editing start point to the editing end point is performed in the playback mode. However, even if only the area around the connection between the editing start point and the editing end point needs to be confirmed, unnecessary time is consumed. An object of the present invention is to provide an editing system that solves the above problems.

[Means to solve the problem]

In the editing system of the present invention, when the designated editing section of the tape is longer than a predetermined length in the preview mode, and the recording VTR is playing back a part of the designated section, the reproducing VTR and the recording VTR It was designed to have soldiers run the tape at high speed.

[For use]

According to the present invention, in the preview mode for checking before executing VTR editing, the WA collection/collection specified section is divided into cases where it is short and cases where it is long, and when it is long, the recording side VTR plays back a part of the editing specified section at high speed. . Furthermore, by setting the playback VTR to high-speed playback mode at this time, normally played video signals are output only around the editing start point and end point, thereby shortening the preview execution time.

【Example】

FIG. 2 is a diagram showing a schematic configuration of a uA collection system as an embodiment of the present invention, in which 1 indicates registration of wA collection points, ! I is a keyboard that manually inputs commands from the keyboard, 2 is a processor that decodes and executes the manual commands from the keyboard I, and 3 is a processor 2 and VT.
4 is a playback side VTR that performs playback according to instructions from the processor 2, 5 is a recording side VTR that performs recording and playback according to instructions from the processor 2, and 6 is an output of the playback side VTR. Signal and recording side V
This is a monitor changeover switch that outputs the output signal of the TR to a changeover monitor according to a command from the processor 2.
7 is a monitor that displays the video signal from the monitor changeover switch on the screen. FIG. 1 is a flowchart for explaining the operation of the processor 2 during preview execution. The editing start and end points are inputted from the keyboard 1 for each of the reproduction side VTR 4 and the recording side VTR 5, and are stored in the RAM in the processor 2. When a preview execution command is input from the keyboard 1, the processor 2 sets the magnetic recording tape at the pre-roll start position from the editing start point through the interface 3 to the playback side and recording side VTR (St), and then When the magnetic recording tapes of the recording side VTR are respectively set to the pre-roll position, the processor 2 drives both the reproduction side and recording side VTRs for reproduction (S2), and by setting the monitor changeover switch 6 to the recording side, the recording side VTR 5 is set to the pre-roll position. Outputs the output signal from the playback side VTR 4 to the monitor 7 (S3). When the playback side and recording side VTRs reach the editing start point, the processor 2 causes the monitor changeover switch 6 to input the output signal from the playback side VTR 4 to the monitor 7. (54), at this time 31! from the editing start point on the processor! Time S to end point
Calculate the default minimum playback time S from the editing start point
Compare the sum of l and the minimum playback time S defined before the end of editing, and if S≦s, +S, proceed to S9 and AIJ
& Drive the VTR on the playback side and recording side in the normal playback state until the end point, but if S>Sl+32, proceed to S6 and after the minimum playback time S1 has elapsed from the start of the m collection, the VTR on the playback side and recording side will be driven. runs the tape at high speed, performs a high-speed search in a predetermined forward direction (FF search > t mode, then pauses the playback and recording VTRs at the position S2 before the end of editing, S7), and both VTRs perform MA collection. Before the end S2
After confirming that the position is set, play back again to the recording station VTR' on the playback side! I! JJJ Sasel (S8)
, until the editing end point, the monitor selector switch 6 is set to the playback side V.
Maintain the state where the TR output is input to monitor 7 (5
9) Next, at the end point of the FA collection, turn on the monitor changeover switch 6.
The recording side VTR output is switched to the state where it is manually inputted to the monitor 7 (510), and then the predetermined Ss is output from the end point of the m collection.
After the time elapses, the reproduction drive is stopped (511), and the preview operation is completed. Incidentally, FIG. 3 shows a timing chart of the reproducing side and recording side VTRs during preview operation. As described above, when the insert section is long in the preview mode, by performing the FF search in the middle of the insert section, it is possible to shorten the confirmation time around the connection between the editing start point and the editing end point. [Effect of the invention] As explained above, in the preview mode, MA
If the edit specified section is longer than a predetermined length, a part of the edit specified section will be recorded.
By running the tape at high speed on both of the J recording side VTRs, the time required for preview execution can be shortened.
