Abstract

PROBLEM TO BE SOLVED: To improve operability. SOLUTION: When a power supply mode switch selects any mode excepting for an editing mode (S2), various kinds of operation processing at a VTR or a camera is performed (S4) and returned to S1. When the editing mode is- selected (S2) and no editing program is registered (S3), various kinds of editing work processing in the editing mode are executed (S10). When the editing program is already registered (S3), the registered editing program is compared with the tape counter mode of the VTR (S51 S6 and S8) and when they are coincident, editing work is started (S10). When they are not coincident, the counter mode of the VTR is made coincident with the mode of the editing program (S7 and S9) and editing work is started (S10).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a VTR with a built-in editing function having an editing function for editing a recording signal of a recording medium using an external recording device which can be remotely operated.

[0002]

2. Description of the Related Art Conventionally, in a state in which at least one or more editing programs are already set and stored, an operation mode other than the edit mode (for example, a VTR playback mode or the like) is again performed.
When the edit mode is selected and the tape counter mode of the set editing program is different from the tape counter mode currently selected on the VTR, editing with a different tape counter mode is not possible. In order to make the following settings in the editing program,
Work such as change and execution is prohibited,
In addition, the user is not notified that the setting of the editing program is prohibited.

When an editing mode is selected in a state where no editing program has been set and stored,
Unless the counter mode of the editing program is separately set, operations such as setting, changing, and executing the editing program cannot be performed.

[0004]

In the conventional example, if the tape counter mode of the editing program already set is different from the tape counter mode currently selected on the VTR, the editing program is temporarily stopped. The tape counter mode of the VTR had to match the tape counter mode of the editing program mode, which was very troublesome. Further, setting of the editing program and the like are prohibited without any notice to the user, so that the user is confused and sometimes mistaken for a failure.

Further, when an editing mode is selected in a state where no editing program has been set and stored, in the prior art, the counter mode of the editing program must be separately set before selecting the editing mode. It was troublesome.

An object of the present invention is to provide a VTR with a built-in editing function that solves these problems.

That is, according to the present invention, when the tape counter mode of the already set editing program is different from the tape counter mode currently selected by the VTR, the editing program and the VTR mode are automatically set. An object of the present invention is to present a VTR with a built-in editing function that is matched.

The present invention is also directed to a case where the tape counter mode of the editing program already set is different from the tape counter mode currently selected on the VTR.
An object of the present invention is to present a VTR with a built-in editing function for notifying a user of the reason for prohibiting editing work.

Further, the present invention further automatically changes the tape counter mode of the VTR to the tape counter mode of the editing program when the editing mode is selected in a state where no editing program has been set and stored. The purpose is to present a VTR with a built-in editing function to be matched.

[0010]

A VTR with a built-in editing function according to the present invention executes editing of a signal recorded on a recording medium using an external recording device which can be remotely operated, according to at least one or more editing programs. Editing VTR with at least two tape counter modes
When at least one editing program is already set and stored, and the editing mode is selected from the operation modes other than the editing mode, the tape counter mode of the already set editing program is Current VT
R is compared with the tape counter mode selected by R, and when the tape counter mode is different, the tape counter mode of the VTR is automatically changed to the tape counter mode of the editing program. Before editing, set the tape counter mode of the set editing program and the tape counter currently selected on the VTR.
Since the mode always matches, the editing work does not have to be prohibited. Also, once you exit the edit mode,
The troublesome operation of resetting the tape counter mode of R to the same mode as the tape counter mode of the editing program mode becomes unnecessary.

The VTR with a built-in editing function according to the present invention also
A VTR with a built-in editing function having at least two tape counter modes, which executes editing of a signal recorded on a recording medium using an external recording device that can be remotely operated, according to at least one or more editing programs. When the edit mode is selected from operation modes other than the edit mode in a state where at least one or more edit programs are already set and stored, the tape counter mode of the already set edit program and the current VTR are set. Is compared with the tape counter mode selected in the step (a), and when the tape counter mode is different, the tape counter display of the VTR is changed to a warning display different from a normal one, and the setting, change and execution of the editing program thereafter are performed. Is prohibited.

Thus, the user is notified of the reason for prohibiting the editing operation, so that the user can easily cope with this situation.

A VTR with a built-in editing function according to the present invention
A VTR with a built-in editing function having at least two tape counter modes, which executes editing of a signal recorded on a recording medium using an external recording device that can be remotely operated, according to at least one or more editing programs. If the editing mode is selected when no editing program has been set and stored, the tape counter mode currently set on the VTR is automatically set to the tape counter mode of the editing program. Then, it is possible to perform operations such as setting, changing, and executing the editing program thereafter.

This eliminates the need to check the tape counter mode currently set on the VTR and set the same mode as the tape counter mode of the editing program, thereby improving operability.

The power supply mode switch 36 is a switch for selecting a power supply mode (camera, VTR, editing, off) of the main body. The system control circuit 22 reads the state of the power supply mode switch 36 to read the camera unit and the power supply mode. The power mode and the operation mode of the VTR section are set to predetermined ones.

FIG. 2 is a flowchart showing the operation of this embodiment. A state change due to the operation of the power supply mode switch 36 is monitored (S1). When the state change is detected, it is determined which mode the power supply mode switch 36 has been operated or selected (S2). If a mode other than the edit mode is selected (S2), various operation processes of the VTR or the camera are performed (S4), and the process returns to S1. If the editing mode is selected (S2), it is determined whether or not an editing program has already been registered (S3). If no editing program has been registered, various editing work processes in the editing mode are executed. (S10).

Go to 0).

The tape of the currently registered editing program
Even when the counter mode is the linear time counter mode (S5), the tape counter mode currently selected by the VTR is confirmed (S8). VTR
If the currently selected tape counter mode is the linear time counter mode in (S)
8) Since both tape counter modes match, various editing work processes in the editing mode are immediately performed (S10).
Move to If the tape counter mode currently selected by the VTR is not the linear time counter mode (S8), the tape counter mode of the VTR is set to linear so that both tape counter modes match.・ Change to time counter mode and set (S
9) Then, various editing work processes in the editing mode (S1)
Go to 0).

As described above, in the flowchart shown in FIG. 2, when the tape counter mode of the VTR does not match the tape counter mode of the edit mode, the VT
Since the tape counter mode of the R is forcibly made coincident with the tape counter mode of the editing program, the editing program and the tape counter mode of the VTR are started at the stage of starting various editing work processes (S10) in the editing mode. Are guaranteed to match. Therefore, it is possible to avoid an incomprehensible operation in which the editing operation cannot be performed while the editing mode is being entered.

FIG. 3 shows a second operation flowchart of the present embodiment. A state change due to the operation of the power supply mode switch 36 is monitored (S11). When the state change is detected, it is determined which mode the power supply mode switch 36 has been operated / selected (S12). If a mode other than the edit mode is selected (S12), various operation processing of the VTR or the camera is performed (S14), and the process returns to S11. If the editing mode is selected (S12), it is determined whether or not an editing program has already been registered (S13). If no editing program has been registered, various editing work processes in the editing mode are executed. (S20).

If the editing program has been registered (S1
3) It is checked whether the tape counter mode of the currently registered editing program matches the tape counter mode of the VTR (S15, S16, S18).
If both the currently registered editing program and the tape counter mode of the VTR are in the linear time counter mode (S15, S18) or both are in the time code counter mode (S15, S16), the editing is performed. The processing shifts to various mode editing work processing (S10).

The tape of the currently registered editing program
If the counter mode does not match the tape counter mode of the VTR (S16, S18), the system control circuit 22 transmits display data to the OSD control circuit 26,
Change the tape counter display of the VTR to a warning display (for example, reverse / flashing display), and
The user is notified that the counter mode and the tape counter mode currently selected in the VTR do not match (S17), and various editing operations in the editing mode thereafter are prohibited (S19).

FIG. 4 shows a display example when the editing program matches the tape counter mode of the VTR.
Is a display example when the editing program and the tape counter mode of the VTR do not match. In FIG. 4, reference numeral 40 denotes the total time of the editing program cut, and reference numeral 42 denotes the current tape counter of the VTR (FIG. 4).
In, the time code counter mode is set. ), 44 is a cut-in guide display, 46 is a cut-out guide display, 48 and 50 are the contents of the first and second editing programs (time code counter mode), respectively, 52 is the next input of the editing program It is a cursor indicating a possible position and a counter bar indicating waiting for input. Reference numeral 54 denotes an edit setting mode, 56 denotes an edit / delete mode, 58 denotes an edit rehearsal mode, 60 denotes an edit execution mode, and 62 denotes a guide display which indicates an all edit delete mode.

The editing program and the VTR are arranged so that the tape counter mode of the editing program is a time code counter, while the tape counter mode of the currently selected VTR is a linear time counter. If the tape counter mode does not match, the tape counter display 64 of the VTR is inverted / blinking as shown in FIG.

FIG. 6 is a flowchart showing a third operation of this embodiment. A state change due to the operation of the power supply mode switch 36 is monitored (S21). When the state change is detected, it is determined which mode the power supply mode switch 36 has been operated / selected (S22). If a mode other than the edit mode is selected (S22), various operation processing of the VTR or the camera is performed (S24), and the process returns to S21. If the edit mode is selected (S22), it is determined whether or not an edit program has already been registered (S23). If at least one edit program has been registered, various edit work processes in the edit mode are performed. Execute (S26).

If no editing program has been registered (S23), the tape currently selected by the VTR
The counter mode is set to the tape counter mode of the editing program (S25), and various editing work processes in the editing mode are executed (S26).

As described above, also in the flowchart shown in FIG. 6, since the tape counter mode of the editing program and the tape counter mode of the VTR match before executing various editing work processes, the editing mode is unnecessarily set. It is not necessary to prohibit processing.

[0036]

As described above, according to the present invention,
Since the tape counter mode of the VTR is forcibly made coincident with the tape counter mode of the editing program which has already been set, the VTR is temporarily exited from the editing mode.
Manually setting the tape counter mode to match the tape counter mode of the editing program, and re-entering the editing mode without having to take a roundabout method.

When the tape counter mode of the editing program already set is different from the tape counter mode currently selected on the VTR, the tape counter display of the VTR is changed to a warning display different from the usual one. By changing this, the user is notified of the reason why the editing operation is prohibited.
Change of the tape counter mode of the TR, etc.).

Further, if the editing mode is selected in a state where no editing program has been set and stored, the tape counter mode currently set in the VTR is changed to the tape counter mode of the editing program. Automatically setting the counter mode of the editing program separately is unnecessary, and the operability is improved.
