Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an editing device that controls a plurality of video tape recorders (VTRs).

Recently, an editing device 1 as shown in FIG. 1 has been proposed which controls a plurality of VTRs. In this Figure 1, 2 is a central processing unit (CPU) as a control unit, 3 is a read-only memory (ROM) that contains software and is used for reading only and outputs to the CPU 2, and 4 is described later. register B ₁ ,
Register B ₂ , . . . indicates an edit number register that stores which of the registers B ₁₂₈ is called or is being called into register A as a work area.

B ₁ , B ₂ , ...Bn indicate registers as data areas corresponding to, for example, 128 edits, and each of these registers B ₁ , B ₂ , ...B ₁₂₈ has a reel number (2 (for A-B rolls that use two playback tapes at the same time, there are two), the type of edit mode (assemble mode or insert mode), the type of source (e.g. VTR, camera), and the start of editing for each playback VTR and recording VTR related to editing. point (IN point) and editing end point (OUT point),
The editing start point (IN point) of the audio signal is memorized to be useful for editing. registers such as
Bi (i=1, 2, . . . 128) is called to register A as a work area in a predetermined case so as to participate in the editing operation. In other words, these registers store data stored in any register.
It functions as a random access memory that is read or written according to the register specification by the CPU 2.

Further, numeral 5 indicates a key block for the editor to issue commands, and the commands from this key block 5 enable desired commands to be transmitted to the CPU 2 via the key interface 6. 7 indicates a display block that displays information necessary for editing such as reel number and time code.
A display signal is transmitted from the display interface 8 through the display interface 8.

9 indicates a recording VTR, 10, 11, . . . 19 indicates a reproduction VTR, and these VTRs 9, 10, 1
1,...19 are VTR interfaces 20, 21,
...30 to communicate with CPU2.

Specifically, the key block 5 mentioned above is an entry key 3 for inputting editing data.
1. Edit key 32 for inputting edit numbers, reel number key 33 for inputting reel numbers, numeric key block 34 for inputting numerical values, GO to (GO) used for auto search.
TO) key 35 and the like are provided in the center of the controller 36 as shown in FIG. Further, an eject key 37, a search dial 38, etc. related to the playback VTR 10 etc. are provided on the left side of the top surface of the controller 36, and a key block 39 related to the recording VTR 9 is provided on the right side of the top surface of the controller 36.
. Furthermore, the controller 36 includes
Such a VTR corresponds to the VTR directly involved in editing.
display device 40,4 indicating the tape position for
1 and 42 are provided as shown in the figure. In this example, there are two displays for playback so that only VTRs related to direct editing are displayed.
Although only the VTRs 40 and 41 are used for display, each of the VTRs 10 to 19 may have one display device.

Further, each of the reproduction VTRs 10, . . . 19 is provided with an auto mode and local mode selection switch (not shown), so that it operates independently of the controller 36 when the local mode is selected. Note that the other parts are configured in the same manner as the conventional editing apparatus.

According to the editing device 1 having such a configuration, the individual registers B ₁ , B _{2 ,} . This allows you to smoothly specify the edit point using the register each time you edit an event. Therefore, for example, using a plurality of playback master tapes, a plurality of playback VTRs 10,
Since you can edit using 11...19, even if you use a master tape with multiple events recorded,
It is possible to select the tape corresponding to the reel number in the register at the appropriate time and perform editing operations.

If the editing device 1 uses such multiple playback VTRs and attempts to use the playback VTRs that are inoperable due to the power being turned off or otherwise and cannot be directly involved in the editing work, the If the editor was not aware of such a situation, there would be the inconvenience of continuing pointless editing work using a non-operating VTR.

In view of this, the present invention is in an inoperable state.
The aim is to provide an editing device that eliminates meaningless editing work using a VCR.

An embodiment of the editing apparatus of the present invention will be described below with reference to the drawings.

In this example, a means is provided to detect that the playback VTR is inoperable for editing, and when an attempt is made to edit using a VTR that is in an inoperable state, the status is displayed on the display device to the editor. The editing device is configured to issue a warning, and other parts are configured in the same manner as a conventional editing device.

The operation of this embodiment will be explained below with reference to FIG. VTR10-1 for playback when editing starts
For example, the playback VTR you are trying to use out of 9.
Whether or not the power to VTR10 is turned off, the VTR
It is determined whether or not the mode No. 10 is a local mode that operates independently of the controller 36, and whether or not it is in a cassette up state, based on a signal indicating the operating state from the VTR 10. If any of the above applies, set the VTR control flag to “0”.
, and the display on the display device 40 is blanked to display an error message. Therefore, depending on the display state
It is possible to notify the editor that the VTR 10 cannot be edited due to reasons such as the power being turned off. In particular, when an editing operation is attempted, the editor is always warned by the display device 4 of the tape position that the editor sees, so that the editor can immediately know of such a situation. Also, neither of these apply here.
When the VTR 10 is ready for operation, the VTR control flag is set to "1", and if an error is displayed, the error display is stopped and the editor is instructed to make the playback VTR 10 ready for operation. Make it known. Next, it is determined whether or not an editing operation using a Goat Wookey 35 or the like has been performed on the VTR 10 for auto-research, and if an editing operation has been performed, the VTR control flag is set to "1". For example, since the VTR 10 is operable and editing can be carried out as it is, the editing work proceeds according to the operation keys. Even if an editing operation is performed here, if the VTR control flag is "0", the VTR cannot operate, and an error is displayed. Here, as an error display, as described above, the display on the display device 40 that displays the tape position of the VTR 10, etc. is blanked to immediately notify the editor that the VTR 10 cannot operate. Furthermore, in order to ensure that the editor is immediately notified of whether or not the VTR 10 is operable during the editing operation through the error display, the above-described routine is repeated one after another. Therefore, for example, even if it is detected that the playback VTR 10 cannot operate due to the power being turned off, the VTR control flag becomes "0" and the display device 40 becomes blank, an error occurs when the VTR is turned on. Since the display is stopped, the editor can immediately know that the editing will proceed as instructed. It is assumed that other editing operations and the like are performed in the same manner as in conventional editing devices.

As described above, according to the editing device of the present invention, when controlling multiple VTRs to perform editing work, it is possible to use a playback VTR that is in an inoperable state and cannot be directly involved in the editing work. If so, it is immediately detected and the display device 40
The blank state allows the editor to be immediately alerted to such a situation. Therefore, even if the editing work is complicated and prone to errors, such as using multiple VTRs at the appropriate time and editing while controlling them, the continuation of meaningless editing work is prevented, and you can rest assured that you will not waste your time and effort. You can perform editing work efficiently and comfortably without any hassle. Additionally, since the display device 40 is used to issue a warning, there is an advantage that the editor can easily find the error.

Furthermore, in the above-described embodiment, an example was described in which the display device 40 is blanked as an error display, but the display device 40 may be
It is easy to understand that any display means may be used as long as the information can be reliably communicated to the editor.

It goes without saying that the present invention is not limited to the above-described embodiments, and can take various other configurations without departing from the gist of the present invention.
