A program is searched by writing an Address Search System) signal and searching the VISS signal or the VASS signal. In this case, the contents of the program in which the VISS signal or the VASS signal is recorded must be stored by the user or written down on a paper label or the like. In order to avoid this trouble, VISS signal or VA
Information such as the title of the program recording the SS signal and the tape position is stored in a storage means provided inside the VTR,
A VTR has been developed that displays the information on a display device.

FIG. 9 is a block circuit diagram of a conventional VTR, and FIG. 10 is a diagram showing an example of connection of the conventional VTR and an example of displaying cassette information. In FIG. 9, 200 is a VTR,
201 is another VTR, 4 is a display device, and VTR20
In 0, 1 is cassette number reading means, 2 is an operating section, 3 is a control head, 5 is input / output means, 6 is editing means, 7 is storage means, 8 is reel motor drive means, and 9 is
Is a motor, 10 is a video / audio input / output terminal, 11 is a video / audio processing means, 202 is a signal transmission cable from VTR 200 to VTR 201, and 203 is VTR 201 to VTR 2.
00 signal transmission cable. Further, in FIG. 10, 204 is a signal transmission cable from the VTR 200 to the display device 4, 20 is a cassette information display screen (hereinafter referred to as “menu screen”) displayed on the display device 4, and 21 is a cursor.

The operation of the VTR shown in FIG. 9 will be described. When the user inserts the video cassette with the bar code representing the cassette number pasted into the VTR 200, the cassette number reading means 1 of the VTR 200 reads the bar code pasted on the video cassette and inputs it to the input / output means 5. The input / output unit 5 reads the cassette information corresponding to the cassette number represented by the barcode from the information stored in the storage unit 7 in advance, outputs this to the editing unit 6, and the editing unit 6
Selects the information to be displayed from the inputted cassette information and outputs it to the input / output means 5, the input / output means 5 outputs the cassette information to the display device 4, and the display device 4 displays the screen 20 of FIG.
The cassette information is displayed as shown in. When the user operates the operation unit 2 and moves the cursor 21 on the menu screen 20 to specify the number of the program to be viewed, the VTR 20
0 searches for a program.

The data stored in the storage means 7 is the cassette tape number and the VISS recorded on the tape.
It is cassette information such as data on the number and position of signals and VASS signals, date of recording the program, title of the program input by the user through the keyboard 2 and edited by the editing circuit 6 and data of character information. The stored information is displayed by outputting the data corresponding to the cassette number to the display device 4 when the cassette number reading device 1 reads the cassette number after inserting the video cassette into the VTR.

Next, the operation of the VTR 200 when searching for a program from the displayed cassette information will be described with reference to the drawings. In FIG. 10, when the cursor 21 is moved to specify the program number to be viewed, the VTR 200 is first displayed.
Starts the tape running, reproduces the control signal, reads the position data of the first detected VASS signal from the storage means 7 to obtain the current position of the tape, and the VISS corresponding to the program specified based on this information. The position data of the signal or the VASS signal is read from the storage means 7, and the motor drive circuit 8 drives the motor 9 in accordance with the value of the difference between the searched position data and the current position data to fast-forward or wind the tape. Perform the return operation. At this time, the control head 3 always reads the control signal of the magnetic tape. When the target VISS signal or VASS signal is read, the motor 9 is immediately stopped and the search for the program is completed.

When a plurality of VTRs are connected to copy or edit a program, a device is connected as shown in FIG. 11, for example. Cable 204 between VTR 200 and display device 4
, And connect it to the VTR200 video / audio output terminal 10 and V
Connect the video and audio input terminals of TR201 to cables 202 and 2
Connect with 03.

The VISS signal set in the VTR 200,
The contents of the magnetic tape on which the VASS signal is recorded are recorded in the VTR2.
When copying to another magnetic tape set to 01, the video / audio processing means 11 reproduces the program recorded on the magnetic tape and outputs it to the input / output means 5. Input / output means 5
Input / output video / audio signals to video / audio input / output terminal 10
Output from the VTR 20 through the cable 202.
It is input to the VTR 201 from the video / audio input terminal 1.
The VTR 201 records this signal on the magnetic tape. At this time, since the control signal recorded on the magnetic tape is newly generated by the VTR 201 with the vertical synchronizing signal of the video signal as a reference, the VISS signal and the VASS signal recorded on the magnetic tape of the VTR 200 are the VTR signals.
It is not copied to the magnetic tape 201. Also, VTR2
The cassette information stored in the storage means 7 of 00 is also not copied.

[0009]

In the conventional VTR, the cassette information stored in the storage means cannot be transferred to another VTR. Therefore, when it is desired to store the same cassette information in the storage means of another VTR, the same information must be input again. Further, the control signal including the index signal recorded on the magnetic tape is not copied, and therefore the additional information such as the VISS signal and the VASS signal is not copied. Therefore, if the same additional information is to be transferred to another cassette tape, the same additional information must be input again.

The present invention has been made in order to solve the above-mentioned problems, and the cassette information stored in the storage means of the VTR and / or the additional information such as the index signal recorded on the magnetic tape can be transferred to other sources. It is intended to be able to be copied to the storage means of a VTR and / or a magnetic tape.
