Abstract

PURPOSE:To automatically edit output signals of plural VTRs in one long tape so as to reduce the labor required for exchanging tapes of each VTR, by sending out output signals of plural VTRs by switching them with a switcher. CONSTITUTION:A switcher 11 selectively outputs the output signal of a VTR 1 by control signals to supply the output signal to a VTR 12 for recording. The VTR 12 for recording is already started by the control signal of a control circuit 13 and records the output signal on a long video tape. On the other hand, VTRs 2-5 sets the cartridge tapes on standby in a program serching state at several seconds before the starting position of commercial messages. The VTR 2 is started several seconds before the reproduction of video signals and the switcher 11 selectively outputs the output signal of the VTR 2 following to the completion of the reproduction of the video signal. The VTR 12 continuously records the video signal of the VTR 2 after completing the recording of the video signal of the VTR 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a video signal editing system for transmitting I1Ii signals of a plurality of programs in arbitrary combination.

Conventionally, when playing multiple programs continuously using a video tape recorder (VTR) at a television station, etc.,
Is it possible to load one tape recording the image signal of one program into each of a plurality of VTRs, operate the plurality of VTRs one after another at a predetermined time, and play back while switching the output signals?1. Alternatively, it is common to edit various programs into one long videotape in advance, and then reproduce and output continuous programs using the edited long videotape.

However, for example, commercial programs have a short duration of about 15 to 80 seconds, and
The number of programs per day reaches about 1,000, so in order to prevent accidental program switching or transmission during on/air, it is necessary to prepare one day's worth of commercial program video signals in advance, one at a time, in the order of transmission. Or he edited it into several video tapes, which were sequentially released on VTR for each commercial broadcast time.
A so-called single commercial system is adopted in which commercials are reproduced and transmitted.

Conventionally, when editing a videotape using the above-mentioned single-commercial system, one commercial program (video signal) is recorded on each roll of video tape in the form of a cartridge, and one commercial program (video signal) is recorded on each video tape on multiple VTRs. Load the videotape and transfer the output signal of each VTR to the recording VT.
This is done by sequentially recording R on one long tape. Therefore, after each VTR finishes playing one videotape, it must quickly switch to another videotape in preparation for the next playback. Moreover, since the video tapes in each VTR must be replaced manually, there is a drawback that it requires a great deal of labor and time.

VTRs are also known that are equipped with a video tape storage section that can accommodate multiple video tapes and an automatic tape exchange mechanism, and have the function of automatically exchanging tapes. Continuous transmission of multiple programs is not possible due to the time required. Therefore, even though the number of steps involved in changing tapes is simplified, the situation remains that multiple programs must be edited onto one long tape using a storage VTR.

As mentioned above, the commercials for the day are printed on one long tape.
The contents of the commercial program will be published later,
When there is a change in the sending order, it is necessary to perform m collection again. In addition, if the above changes occur after a commercial that has been combined into a long videotape is put on a VTRK and transmission has started, re-editing is not possible, and the changed parts must be changed manually. There are many inconveniences such as having to perform switching transmission.

SUMMARY OF THE INVENTION An object of the present invention is to provide a video signal editing method that solves the above-mentioned conventional drawbacks and allows image signals of a plurality of programs to be arbitrarily switched and continuously transmitted.

The editing system of the present invention includes a plurality of VTRs having an automatic tape exchange function, a switcher that inputs the output signals of the several 4i VTRs and selectively outputs them, and
Two tape exchange operations.

A plurality of tapes are stored in each of the plurality of VTRs, and each switcher is configured to control the plurality of tapes under the control of the control circuit. It is characterized in that an arbitrary number of programs can be sent out continuously by switching the output of the VTR.

When using this editing system, it is possible to connect the output signal of the switcher directly to broadcasting equipment and continuously transmit a plurality of arbitrary programs at an arbitrary time period. By recording the output signal of the switcher mentioned above on a long tape using a recording VTR, it is of course possible to edit multiple programs consecutively and record them as one, providing a highly flexible editing method. It is a method.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

That is, multiple video tape recorders (VTRs) 1
5, the cartridge tape groups 6 to 10 housed in each VTR0's self-mf exchange mechanism, and the output signals of the plurality of VTRs mentioned above are input, and an arbitrary control signal is inputted by the control signal given from the control circuit (CONTROL) 18. It is comprised of a switcher 11 that selectively outputs VTR output signals, and a recording VTR 12 dedicated to recording that records the image signals output from the switcher 11 onto one long tape.

The VTRI has an automatic tape exchange function and a control circuit 18.
This is a playback-only VTR that performs operations such as replacing and locating the beginning of any cartridge tape in the tape group 6 and starting and stopping playback based on control signals given from the tape group 6. VTR like this
You can use widely used ones. A description of the mechanism for automatic tape exchange will be omitted.

The same applies to VTRs 2 to 6. Further, cartridge tape group 6 includes cartridge tape T1. T@＊'I
There are six cartridge tapes: 'll・T,・eT't+, and cartridge tape #7 is cartridge tape T! ,..."Tt S Cartridge tape group 8 is cartridge tape T S 1..., T
This is a cartridge tape from Goose 1. The same goes for cartridge tape $9.10. And now cartridge tape T.

The image signal CM of the first commercial is recorded on the cartridge tape T, ~T, and the second commercial image signal CM is recorded on the cartridge tape T, ~T, respectively.
~26th commercial image signal CM.

Next, the operation of this embodiment will be explained. FIG. 2 is a time chart showing the operation sequence of this embodiment.

First, the j9VTR1 is activated by a control signal from the control circuit 18, and the first commercial image CM No. m is recorded on the cartridge tape T1.

is played back and output. The switcher 11 selects and outputs the output signal of the VTRI according to the control signal and outputs the VTRI output signal to the recording VTR 12.
supply to. VTR12 for recording.

It has already been activated by the control signal of the control circuit 18.
The output signal of the switcher 11 is recorded on a long video tape. On the other hand, the VTRs 2 to 6 are on standby with their respective cartridge tapes T, . Then, seconds before the playback of the 1 image signal CM is OK, the VTR2; 6! Start up and 1Ilii image signal CM.

Following the completion of reproduction, the switcher 11 selectively outputs the output signal of the VTR 2. The VTR 2 is in a stable operating state within seconds after startup. Therefore, the VTR 12 can record the painter signal CM, followed by the image signal CM. On the other hand, the VTRI, which has finished playing the cartridge tape T, performs a tape exchange operation to replace the cartridge tape T, and waits in front of the material by a cue operation. The above-mentioned tape exchange operation and the like can be carried out in time for the end of reproduction of the cartridge tape T, so there is enough time to do so. Upon completion of the image signal CM1, the reproduction signal of the cartridge tape T is output from the VTR 8 in the same way as described above. When the reproduction of the cartridge tape T is completed as described above, the Iji image signal CM recorded on the cartridge tape T6 is now reproduced and output from [FivTRY].

In this way, the cartridge tape T, ~T! .

were played sequentially and recorded on each tape.
125 commercial image signals CMI to CMIm are continuously sent out from the switcher 11 and sent to the recording VTRI! The video is edited and recorded on one long videotape. Each V
After all the cartridges stored in TRs 1 to 6 have been removed, it is also possible to take out the recycled cartridge tapes and supplement the light with new cartridge tapes. In this way, it is possible to edit all the commercial material for one day using 26 or more tapes into one.Each operation of 0 or more is of course performed in accordance with the control signal output from the control circuit 18. .

In the above description, a case has been described in which a recording VTR 12 is provided and a single long videotape is recorded as a whole. Of course, it is also possible to input the information. In addition, each cartridge tape 1 to 25 not only carries the image signal of one commercial, but also
For example, it is also possible to record image signals of a plurality of commercials that are divided and edited for each commercial transmission time slot. In this case, even if it becomes necessary to urgently change the content, order, etc. of commercial transmission, this can be easily handled by re-editing only the cartridge tape in the time period in which the change is required. Not only is it time-consuming to change the editing of a day's worth of long tape, but it is also impossible to change the editing if the long tape is in use, even if the part is not related to the change. It is very convenient because there is no such thing. The various editing methods described above can be used in any combination, and are highly flexible editing methods.

[ Since the KII is configured so that the output signals of several VTRs can be switched and transmitted by a switcher, it is possible to automatically edit the output signals of the switcher into one long tape. ), each VTR
This has the effect of significantly reducing the time and labor involved in replacing tapes, etc. It is also possible to directly input the output signal of the switcher to the broadcasting equipment, and
Each V7 cartridge tape can be edited with great flexibility, including the ability to record a series of multiple commercials.
