Description

Copy VRL

The present invention relates to a VC, and more particularly, to a copy VRC capable of switching an applied reproduction signal.

Copy V-al (also known as Duplicator) is a form of multi-function V-Cal with a number of (at least two) decks, the contents contained on one source tape It refers to a device capable of copying contents contained in a plurality of target tapes or a plurality of playback tapes to a single recording tape.

The former is the method used to copy large amounts of videotape at the same time, and the latter is the method required for detailed editing of the contents on the tape.

In the former case, since a plurality of recording decks and one playback deck are fixedly connected, there is a problem that the contents recorded on the playback tape cannot be divided and copied to each recording tape.

Accordingly, the present invention has been made in view of the above-described problem, and an object thereof is to provide a copy VRL for switching an applied reproduction signal to at least two recording decks.

In order to achieve the above object, the present invention provides a reproduction deck for driving in a regeneration mode upon application of a regeneration drive signal; At least two recording decks which drive in a recording mode upon application of a recording drive signal to record a video signal reproduced from the reproduction decks on a magnetic tape; A switching unit for switching the reproduced video signal to respective recording decks according to the switching control signal; A key input unit for outputting a copy signal or a switching signal; And a control unit for applying a reproduction driving signal to the reproduction deck when the radiation signal is applied, applying a recording drive signal to the recording decks, and applying a switching control signal to the switching unit when the switching signal is applied. To provide a copy VRC.

The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

Prior to the description, the recording deck of the copy V-al according to the present invention was limited to three for convenience, the number may be added according to the manufacturer.

1 is a functional block diagram of a copy VR in accordance with the present invention, the playback deck 10, the recording deck 20, (22), (24), the switching unit 30, the key And an input unit 40 and a microcomputer 50.

Among them, the key input unit 40 includes a plurality of keys (not shown) for performing various functions (reproduction, recording, high speed copying) of the VDL for copying, and a key signal corresponding to the pressed key and The switching key signal is applied to the microcomputer 50.

The playback deck 10 reads the contents recorded on the video tape (not shown) in response to the copy key signal of the key input unit 30.

In addition, the recording decks 20, 22, and 24 are driven in the recording mode according to the copy key signal of the key input unit 30, and thus the video and audio signals reproduced from the above-described reproduction deck 10 are reproduced. Write on magnetic tape.

The switching unit 30 according to the present embodiment is selectively switched to each recording deck according to the switching control signal of the microcomputer 50.

On the other hand, the microcomputer 50 applies a reproduction driving signal to the reproduction deck 10 in response to the copy key signal from the key input unit 30, and records the recording decks 20, 22, and 24. Apply the drive signal. In addition, the microcomputer 50 applies the switching control signal to the switching unit 30 in response to the switching key signal from the key input unit 30, thereby recording the video and audio signals read from the deck 10 for reproduction, respectively. Switch to the dragon decks (20), (22) and (24).

Then, with reference to the flow chart of Figure 2 attached to the switching unit of the switching V30 of the copy VR in accordance with the present invention together with the above-described configuration will be described in detail.

Prior to the description, the flow chart exemplifies a case in which the playback deck is reproduced and driven during the recording drive by the copy control signal of the microcomputer.

First, when the recording deck 20 switching key located on the own panel or remote control of the copy VR is pressed by the user, the key input unit 40 transmits the recording deck 20 switching key signal to the microcomputer 50. (Step 100).

The microcomputer 50 applies the recording deck 20 switching control signal to the switching unit 30 so as to correspond to the recording signal of the recording deck 20 of the key input unit 40, so that the reproduced signal to be applied is the recording deck. It is switched to 20 (step 102).

If the recording deck 22 switching key signal is input from the key input unit 40 to the microcomputer 50 (step 104), the microcomputer 50 switches the recording deck 22 switching control signal to the switching unit 30. By applying, the applied reproduction signal is switched to the recording deck 22 (step 106).

Finally, when the recording deck 24 switching key signal from the key input unit 40 is applied to the microcomputer 50 (step 108), the microcomputer 50 switches the recording deck 24 to the switching unit 30 for control. By applying the signal, the applied reproduction signal is switched to the recording deck 24 (step 108).

As described above, the present invention has the effect of switching the reproduction signal of the copy VR.
