Abstract

According to the present invention, a VRT having an audio deck is further provided so as to control separately the audio signal output from the audio deck during dubbing so as to be used as an audio signal source according to the dubbing. As a video tape editing apparatus, when dubbing in a conventional VR according to the prior art, it is very difficult to dub personally because it requires equipment such as a cassette or a cassette player for an appropriate sound source. In the present invention, an additional audio deck unit 40 is attached to the V-Cal so that the audio signal reproduced from the audio deck unit 40 can be separately controlled to be used as a source of the audio signal according to the dubbing. It is convenient to be able to improve the above-described drawbacks.

Description

VP Real Video Tape Editing Device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video tape editing apparatus of a video cassette recorder (VCR), and more particularly, to an audio signal output from an audio deck when dubbing in a VRC having an audio deck. A video tape editing apparatus of V-Cal suitable for being used as an audio signal source according to dubbing by controlling it separately.

Briefly, the principle of the Video Cassette Recorder is as follows.

We can easily call it VSI, but it was originally called Video Cassette Recorder, which is the correct name. In Korean, it can be called 'self-recording playback'.

It is a device that records video signals from the outside and records them on tape through the head of VRC.

Here, the head is a kind of electromagnet, which causes a change in the magnetic force according to the electric change, and is recorded by contacting the tape emitting head with the magnetic signal.

At this time, the tape is iron powder coated on the vinyl, the iron powder is magnetized according to the change of the magnetic force of the head.

You can also select the recording speed of VRF.

The recording speed can be divided into standard speed (SP mode) and triple speed (SLP mode or EP mode: 6 hours of use for 2 hours tape).

If you don't have important recordings, you can record at three times the speed, but the video quality is lower than standard speed recording.

In addition, there are two types of home VR, ß type and VHS (Video Home System) type. The basic concept of the two types is the same, and the tape used is 1/2 inch wide.

In this regard, when dubbing in the VR according to the prior art, it is very difficult to personally dub because it must have equipment such as a cassette or a cassette player for an appropriate sound source.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, it is equipped with an additional audio deck on the V-al to allow separate control of the audio signal from the audio deck when dubbing to make the editing of the audio signal very easy. The purpose of the present invention is to provide a video tape editing device of VSI.

In order to achieve the above object, the present invention provides a command input unit for key input for selecting a desired function of V-Cal, a micom for controlling a desired function of V-Cal according to the function selection of the command input unit, and many Tuning unit for tuning the desired broadcast signal from the broadcast signal of the video and audio signal to separate and output each, and audio deck unit for controlling the audio cassette to reproduce the audio cassette when dubbing and output the audio signal, and the microcomputer A switching unit which is controlled by the control unit to select and pass the audio output of the tuning unit or the audio output of the audio deck unit 40 when dubbing, and the output of the switching unit when controlled by the microcomputer as an audio signal source. It is characterized by comprising a deck portion to be used.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, an embodiment of the present invention for achieving the above object in detail.

Referring to FIG. 1, FIG. 1 is a block diagram showing an embodiment of a video CD editing apparatus of a VR in accordance with the present invention, and includes a command input unit 10 for inputting a key to select a desired function of a VR. The microcomputer 20 for controlling a desired function of V-Cal according to the function selection of one command input unit 10, and a tuning unit for separating and outputting video and audio signals by tuning desired broadcast signals among a plurality of broadcast signals, respectively. 30, the audio deck unit 40 controlled by the microcomputer 20 described above to reproduce an audio cassette during dubbing and outputting an audio signal, and the above-described tuning controlled by the microcomputer 20 described above. The switching unit 50 for selecting and passing the audio output of the unit 30 or the audio output of the audio deck unit 40 described above, and the switching unit 50 described above when controlled by the microcomputer 20 described above. And a deck unit 60 using the output of the audio signal source.

The present invention thus made will be described in detail with reference to FIG. 2 as follows.

First, a user selects a desired function of V-Cal by operating a corresponding key through the command input unit 10 to select playback, dubbing, general recording, scheduled recording, and the like, and the microcomputer 20 selects the command input unit 10 described above. The audio deck unit 40, the switching unit 50, the deck unit 60, and the like are controlled to perform a desired function of the V-Cal according to the function selection.

Next, the tuner 30 tunes a desired broadcast signal among a plurality of broadcast signals to separate the video and audio signals, respectively, and outputs the audio deck unit 40. The audio deck unit 40 is controlled by the microcomputer 20 as described above. A cassette is played to output an audio signal.

In addition, the switching unit 50 is controlled by the microcomputer 20 described above, and selects and passes the audio output of the above-described tuning unit 30 or the audio deck unit 40 described above during dubbing.

In particular, in order to use a specific sound source as a source during dubbing, the switching unit 50 should select the audio output of the audio deck unit 40.

The deck unit 60 is controlled by the microcomputer 20 described above to use the audio signal output of the switching unit 50 or the audio signal output of the tuning unit 30 as an audio signal source when dubbing.

Of course, in addition to the above-described audio signal when dubbing, an audio signal may be received from the outside and used as a source.

FIG. 2 is a flowchart showing step by step an embodiment of a video tape editing of VRC according to FIG.

First, when there is a dubbing key input from the command input unit 10, the microcomputer 20 operates the audio deck unit 40 to reproduce an audio tape mounted in the audio deck unit 40 to output an audio signal (110, 120). ).

Next, the switching unit 50 is controlled to allow the audio signal of the audio deck unit 40 to pass so that the deck unit 60 records the audio signal of the audio deck unit 40 as an audio signal on the video tape (130, 140). ).

In this case, if the key input from the command input unit 10 is not a dubbing key input in the above-described step 110, another corresponding function is executed (150).

As described above, according to the present invention, the audio deck unit 40 is additionally mounted on the VRC to separately control the audio signal reproduced from the audio deck unit 40 when dubbing so as to be used as a source of the audio signal according to the dubbing. It is effective to dub a V seed becomes very convenient.
