Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an editing device that sequentially edits a plurality of events (one unit of editing) recorded on a plurality of video cassettes.

Recently, an editing device (1) as shown in FIG. 1 has been proposed. In this Figure 1, (2) is the central processing unit (CPU) as a control unit, and (3) contains software that is used for reading only and outputs to the CPU (21).
The only memory (ROM) (4) is a register B1, a register B2, . . . . indicates an edit number register that stores which of the registers B128 is called to the register person as a work area or is being called.

Each of these registers Bl, B2, ..., B128 contains the reel number (A-
(2 for B-roll), type of edit mode (assemble mode or insert mode), type of source (e.g. VTR, camera), editing start point (IN point) and editing end point for each of the playback VTR and recording VTR related to editing. Point (OUT point), audio signal editing start point (IN point), etc. are stored in memory to be useful for editing work. These registers Bi (i=l, 2, . . . -1128) are called by the register A as a work area in a predetermined case so as to participate in the editing operation. In other words, these registers function as a random access memory in which data stored in any register is read or written by the CPU (21) according to register designation.

Further, (5) indicates a key block through which the editor issues commands, and the commands by this key block (5) enable desired commands to be transmitted to the CPU (2+) via the key interface (6). (The display block (7) K indicates a display block that displays information necessary for editing such as reel numbers and time codes, and this display block (7) K receives display signals from the CPU (2) via the display interface (8). I'll do it like that.

(9) VTR100 for C), αυ, ..., (
VT for IC3 reproduction
R(9), 00), (Ill, 11 fists @1α9 is VTR
Interface (20+, (21),..., C30
) to communicate with CPU (2).

Specifically, the above-mentioned key block (5) includes an entry key c31) for inputting edit data, an edit key 0 for inputting an edit number, a reel number key (33) for inputting a reel number, and a key for inputting numerical values. A numeric key block 04) used for auto-search, a GOTO key Gω used for auto-search, etc. are provided in the center of the controller (3G) as shown in FIG. Also, on the left side of the top of the controller, there is a V T for playback.
An eject key t37) for R (IQ), etc., a search dial 2, etc. are provided, and a keep lock device for the recording VTJ 9) is provided on the upper right side of the controller (g).

1 ta, individual VTR (9), (fO), aaa, (1
Each of the nine screens is provided with an auto mode and local mode selection switch (not shown), and when the local mode is selected, it operates independently of the controller. 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, each register r31. Since B2, **, and B128 can be used as memories corresponding to individual events recorded on the master tape as editing material, each event can be edited smoothly by operating the specified command using the key block (5). Points can be specified by registers. Therefore, for example,
Multiple playback VTs using multiple playback master tapes
Editing using R←υ, aυ, ..., a9 is possible, so even if you use a master tape with multiple events recorded, you can select the tape corresponding to the reel number in the register at the appropriate time and edit efficiently. It is something that can be done.

However, since the editing device does not have a means to detect the reel number of the tape set on the playback VTR, for example (10), and compare it with the memory contents of the edited data in the register, it is stored in the register. Even if a tape with a different reel number was set in VTn (IQ), the editor did not notice it! 11 I continued editing or correcting the points, and an unexpected edit was made. I-There was the inconvenience that there was a possibility of a crash.For example,
I am using it as a playback side for a master tape that only records from the 1st event to the 3rd event, and I finish editing up to the editing end point of the 3rd event, and then try to edit the 4th event. If so, another master tape recording the fourth to seventh events must be used. However, in this case, the playback VTR
Qg) If there is no means to detect the reel number of the tape set in the tape and compare it with the memory contents of the edited data in the register, the first to third events will be used for the fourth event as well. The master tape on which the event was edited was mistakenly assumed to be valid for editing from the editing start point specified for the master tape, and the master tape was not replaced correctly! ,
However, there are cases where editing continues.

In view of this, it is an object of the present invention to provide an editing device that can detect and warn when the tape currently in use is unsuitable for the desired editing or correction that is to be performed next. It is something.

An embodiment of the editing apparatus of the present invention will be described below with reference to FIG. In FIG. 3, parts corresponding to those in FIGS. 1 and 2 are given the same reference numerals, and detailed explanation thereof will be omitted.

In Fig. 3, C (40 indicates a comparison device that compares the reel number of the selected register with the reel number read out on the playback side, and this comparison device (4G indicates that the register A is The reel number and playback V of the edited data of the register selected from registers B1, B2, *e@, and B128 that act as areas and random access memory.
TII, for example, θ0, is compared with the reel number of the tape currently being used to detect whether the numbers match or do not match. If the reel numbers do not match, in other words, if the desired editing work or edit point correction work cannot be continued depending on the current tape playback, an error message will be displayed after checking as described below. Eggplant.

Further, the configuration and operation of the editing apparatus of the present invention will be explained with reference to FIG.

When power is input to the editing device, ``First, register A is set to reel number 101, and all registers Bn (n = l
, . . -1l28) and start editing. Next, it is determined whether the reel number has been changed by manual operation and the contents of register A as a work area are changed. Then, it is determined whether the editing point entry operation has been completed, and in the case of the operation method, it is determined whether the register Bn is blank or not, and the data in the register A is transferred as shown in the fourth diagram. Also, when register Bn is not blank, the data in register A and register Bn are compared by the comparator (40), and if the reel numbers are not equal, it is determined that there is a reel number error, an error is displayed, and the lamp built in the eject button 0η is turned on. The reel error flag is turned on and the reel error flag is set to 1", and the reel number of the correct register Bn is displayed at the predetermined display position. Here, such an error display is performed when the VTR in which the master tape in error is loaded is displayed. If there is no error in the reel number, no error will be displayed.

In addition, if an edit point entry operation has not been performed, it is determined whether or not there is an operation using the GOTO WOO key 0 to cue the edit point, an operation using the G button to change the edit number, or an operation using the auto mode button. If any of the operations is performed here and register Bn is blank, or if register A and register Bn have the same reel number, it is not an error and no error is displayed. Register Bn is not blank and register A and register Bn
If the reel number data are not the same, it is judged as a reel number error and an error is displayed, the eject button 07) lights up the built-in lamp, warns that the tape needs to be replaced, and sets the reel error flag to 1''. Correct register B
The reel number of n is displayed on the display block (4I) to facilitate tape replacement.

On the other hand, if there is no operation using the Goto Wookie (3 buttons, edit number change button, or auto mode button operation), it is determined whether the cassette setup is set or the reel error flag is set to ``1''. When it is determined that the wrong reel has been removed and the error has been cleared, an error display is displayed, the eject button 07) stops the built-in lamp from blinking, the reel error flag is returned to 10'', and the contents of the register are transferred to the correct register Bn. If register Bn is blank or the data in register A and register Bn are the same, no error display will be performed.Please note that such a routine should be repeated many times during the editing process. Therefore, an error message will be displayed immediately and in a timely manner.

As described above, according to the present invention, if the tape currently in use during editing is unsuitable for use in the desired editing or correction to be performed next, the reel number comparison device (401) Since it automatically detects the error and immediately warns you by displaying the error message, there is no need to continue editing by using the wrong tape.Therefore, it has the advantage of being able to perform efficient and accurate editing with peace of mind. .

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that various other configurations may be adopted without departing from the gist of the present invention.
