CONSTITUTION:An OSD screen display output section 12 sets the OSD display screen of an operating section 11, thereby controlling the OSD display screen and making OSD screen display output. The state of the video recording machine 2 is inputted from an input terminal 15 and is inputted to a control section 14. At this time, a switch 17 is put into an off state and only the output video signal of a reproduced video signal output section 13 is inputted to an adder circuit 18 and is outputted to a video signal output terminal 16 when the video recording machine 2 is in a recording state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus which is effectively used in a video tape recorder (hereinafter referred to as VTR).

[0002]

2. Description of the Related Art In recent years, the use of VTRs has increased not only for recording and reproducing and for enjoying, but also for operating and editing by OSD screen display.

The above-mentioned VT will be described below with reference to the drawings.
An example of editing R will be described. FIG. 2 shows a block diagram of editing of a conventional recording / reproducing apparatus. In FIG. 2, 21 is an on-screen display (hereinafter, referred to as O
An operation unit for setting a display screen (referred to as SD). 22
Is an OSD screen display output unit controlled by the setting of the OSD display screen. Reference numeral 23 is a reproduced video signal output unit. 26 is an OSD for a reproduced video signal by an adding circuit 28.
An output terminal for outputting a video signal on which a display screen signal is superimposed. Reference numeral 27 is an output terminal for only the reproduced video signal. Two
An adder circuit 8 superimposes the reproduced video signal and the OSD display screen signal. Reference numeral 29 is a TV that displays the video signal output from the output terminal 26.

The operation of the conventional VTR having the above-described structure will be described below.

In FIG. 2, the OSD screen display output unit 22
Is set by the OSD display screen of the operation unit 21
It controls the display screen and outputs the OSD screen display. The video signal output of the reproduced video signal output unit 23 and the OSD screen display signal of the OSD screen display output unit 22 are superimposed by the adder circuit 28 and output from the output terminal 26, and the output video signal is displayed on the TV 29. . Also, the reproduced video signal output unit 2
The video signal from 3 is also output from the output terminal 27, and this signal is input to the recorder 2. The user edits while viewing the contents of the OSD screen display displayed on the TV 29.

[0006]

However, in the above configuration, the video signal output terminal 27 of the playback video signal output section 23 and the output terminal for outputting the video signal in which the OSD screen display is superimposed on the playback video signal output. Since there are two systems of video signal outputs of 26, there is a problem that the user may erroneously connect the player 1, the recorder 2 and the TV 29.

In view of the above problems, it is an object of the present invention to provide a recording / reproducing apparatus which does not erroneously connect a reproducing device, a recording device and a TV.

[0008]

In order to solve the above-mentioned problems, the present invention provides a control unit for controlling ON / OFF of an OSD display screen depending on whether a recorder is in a recording state, and an OS.
The operation unit for setting the D display screen, the OSD screen display output unit for outputting the OSD display screen set by the operation unit, the reproduction video signal output unit, and the reproduction video signal output from the reproduction video signal output unit. And an adder circuit that superimposes the OSD display screen signal output from the OSD screen display output unit.

[0009]

According to the present invention, with the above-described structure, the control unit determines whether the recorder is in the recording state and controls the on / off of the OSD screen display, so that the output terminal becomes one system and the recorder and the recorder are recorded. It is possible to prevent the wrong connection between the machine and the TV.

[0010]

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

FIG. 1 shows a block diagram of editing of a VTR in this embodiment. In FIG. 1, reference numeral 1 is a player, 2 is a recorder, and 11 is an operation unit for setting an OSD display screen. An OSD screen display output unit 12 is controlled by the setting of the OSD display screen by the operation unit 11.
Reference numeral 13 is a reproduced video signal output unit. 14 indicates whether the OSD display screen is ON / OFF depending on whether the recorder 2 is in the recording state.
It is a control unit that performs off control. Reference numeral 15 is an input terminal for inputting the state of the recorder 2. A video signal output unit 16 outputs a video signal. A switch 17 is switched by the control unit 14. 18 is OSD for playback video signal
It is an adder circuit that superimposes a display screen signal. Reference numeral 19 denotes a TV that displays the signal output from the video signal output unit 16 on the screen.

Regarding the VTR constructed as described above,
The operation will be described. In FIG. 1, the OSD screen display output unit 12 is set to the O
It controls the SD display screen and outputs the OSD screen display.
Then, a signal indicating the state of the recorder 2 is input from the input terminal 15 of the player 1 and input to the controller 14.

At this time, when the recorder 2 is in the recording state, the switch 17 is turned off by the control of the control unit 14, the signal of the OSD screen display output unit 12 is cut off, and the reproduction video signal output unit 13 is turned off. Adder circuit 1 for output video signal only
8 is input. This reproduced video signal is output from the video signal output terminal 16 to the TV 19 and the recorder 2 and recorded by the recorder 2.

If the recorder 2 is not in the recording state, the switch 17 is turned on by the control of the control unit 14, and the reproduced video signal from the reproduced video signal output unit 13 and the O
The OSD display information signal from the SD screen display output unit 12 is input to the adding circuit 18, and a signal in which the two signals are superimposed is generated. This signal is output from the video signal output terminal 16 to T
The data is output to the V19 and the recorder 2, and the user edits while watching the screen of the TV 19.

As described above, according to this embodiment, the signal output from the video signal output terminal 16 is transmitted to the recorder 2 and the TV 19.
In addition, since the control unit 14 controls whether or not to superimpose the OSD display information signal on the reproduced video signal, only one output terminal of the reproducing device 1 is required.

[0016]

As described above, the present invention has an excellent effect that erroneous connection between the reproducing device, the recording device and the TV can be eliminated because the reproducing device has only one output terminal.
