BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Hi-Fi video tape recorder (hereinafter referred to as a VTR) having a voice signal editing function, and in particular, a native language reproduced in a hi-fi tape recording a voice multiple signal. And a hi-fi VTR having a voice signal editing function capable of selectively rewriting foreign languages on a normal track of a tape.

In general, dubbing of voices is often performed during the production of videotape or television dramas. When performing the audio dubbing operation, as well as in other cases, it is frequently necessary to edit only the audio signal separately from the video signal. In the case where the audio signal is a normal voice signal, since there is a separate track for the voice signal on the video tape, an editing function for arbitrarily recording and reproducing the voice signal is possible.

However, when using a Hi-Fi voice signal such as the S-VHS (Super-Video Home System), which is being used in recent years, a left channel (L-CH) for recording a native language on a high-fi tape And a write channel (R-CH) for recording a foreign language and a normal track for recording a native language. To explain the pattern of the high-fi tape further, the audio signal is recorded in the core portion of the magnetic layer of the tape, and the video signal is recorded in such a manner as to duplicate the video signal in two stages. Thus, two kinds of signals are simultaneously present on the tape. When the high-fi tape is played back with a high-fi VTR, a native language and a foreign language can be selected. However, when playing back with a general VTR, only a native language can be played back. Therefore, an editing function of selecting one of a left channel with a native language, a light channel with a foreign language, and a sum signal on a high-tap tape normal track was required.

In the conventional voice editing function, editing is possible only when the voice signal to be recorded on the tape is input from the outside, so that it is impossible to rewrite the voice signal recorded in the cape on the normal track of the tape.

Accordingly, an object of the present invention is to solve the above-described problem, Hi-Fi VTR having a voice editing function that can select the native language and foreign language to be reproduced when playing back the tape in the Hi-Fi VTR and write it back to the normal track of the tape In providing.

It is another object of the present invention to record a foreign language instead of a native language on a normal track of high-fi tape so that a foreign language can be heard when playing a high-fi tape through a high-fi VTR having a voice editing function as described above. It is to provide a hi-fi VTR with voice editing function.

The Hi-Fi VTR having a voice editing function of the present invention for achieving the above objects is a voice editing function in a Hi-Fi VTR of a voice multiplex method for simultaneously broadcasting a foreign language and a native language. An apparatus for performing a video recording apparatus, comprising: a control unit for controlling each configuration according to whether the VTR is a recording mode or a playback mode, and a native language audio signal applied from an external source in the recording mode and outputting the selected audio signal; A first switch unit for selecting and outputting a reproduced native language audio signal, and a second language for selecting and outputting a foreign language audio signal applied from an external source in a recording mode, and selecting and outputting a foreign language audio signal to be reproduced in a reproducing mode A third unit for selecting and outputting one of a native language and a foreign language audio signal applied from a switch unit and the first switch unit and the second switch unit; And a signal processing unit for processing the native or foreign language audio signal applied from the third switch unit to be recorded on the normal track of the tape.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a hi-fi VTR having a voice editing function according to the present invention. As shown, the hi-fi VTR of the present invention receives a voice signal (S _L1 -S _L3 ) from the control unit 11 for controlling each configuration, and from different sources outside and outputs one of them. 1st switch SW1 is provided. In addition, a second switch SW2 for receiving audio signals S _{R1 to} S _R3 from external sources is output. At the output terminal of the first switch SW1, a signal obtained during reproduction of the native language recorded on the output signal S _L of the first switch SW1 and the left channel track L-CH track of a high-fi tape (not shown) is provided. A third switch SW3 that receives an input and outputs one of them is connected. At the output terminal of the second switch SW2, a signal obtained when reproducing a foreign language recorded on the output signal S _R of the second switch SW2 and the light channel track R-CH track of a high-fi tape (not shown). The fourth switch (SW4) for receiving the input and outputs one of them is connected. An adder 12 for obtaining the sum signal L + R of two output signals is connected between the third switch SW3 and the fourth switch SW4. The adder 12 is connected to a fifth switch SW5 that receives an output signal of the third switch SW3, a sum signal of the adder 12, and an output signal of the fourth switch SW4 and outputs one of them. The third switch SW3 also receives the output signal of the third switch SW3 and the local language recorded on the left channel track L-CH track of the high-pipe tape (not shown). A first signal processing unit 13 for recording on the left channel track (L-CH Track) and processing for reproduction is connected. The fourth switch SW4 also receives the output signal of the fourth switch SW4 and a foreign language recorded on the R-CH track of a high-pipe tape (not shown). A second signal processing unit 14 for recording on the R-CH track and processing for reproduction is connected. A third signal processor 15 is connected to the fifth switch SW5 to process the output signal of the fifth switch SW5 to be recorded on a normal track of a high-fi tape (not shown). The first to third signal processing units 13, 14, and 15 are configured to be connected to a matrix unit 16 for outputting the processed three signals as left and right signals L / R according to a predetermined matrix.

The operation of the hi-fi VTR having the voice editing function of the present invention configured as described above will be described in more detail.

First, when the high-fi VTR is a recording mode (REC. Mode), the control unit 11 controls each configuration to fit the recording mode. The first switch SW1 and the second switch SW2 receive voice signals from different external sources through a plurality of input terminals. For example, a voice signal may be input through a tuner, another sound device, or another auxiliary device in the VTR main body. The switching operation of the first switch SW1 and the second switch SW2 is controlled by the control unit 11 according to which source the audio signal is to be selected. The first switch SW1 selects one of the plurality of input signals S _L1 to S _L3 as a signal S _L for recording on the left channel track of the high-fi tape. The second switch SW2 selects one of the plurality of input signals S _R1 to S _R3 as a signal S _R for writing to the light channel track of the high-fi tape. The third switch SW3 outputs the signal S _L received from the second switch SW1 to the fifth switch SW5, the first signal processor 13, and the adder 12. The third switch SW3 receives a signal to be played back from the tape when the VTR is in the play mode, and the control unit 11 performs a switching operation differently for each of the recording mode and the playback mode. The fourth switch SW4 outputs the signal S _R applied from the second switch SW2 to the fifth switch SW5, the second signal processor 14, and the adder 12. The fourth switch SW4 receives a signal reproduced from the tape when the VTR is in the reproducing mode, and the switching unit 11 performs a switching operation differently for each of the recording mode and the reproducing mode. The adder 12 obtains a sum signal S _L + S _R of two voice signals S _L and S _R input from the third switch SW3 and the fourth switch SW4. The sum signal S _L + S _R is input to the fifth switch SW5. The fifth switch SW5 is a high-pipe tape of one of two voice signals S _L and S _R and a sum signal S _L + S _R input from the third switch SW3 and the fourth switch SW4. It is selected as a signal for recording on the normal track. This signal is input to the third signal processor 15. Here, the controller 11 controls the switching operation of the fifth switch SW5 to select the sum signal when the input signal is stereo or mono, and to select one of a native language or a foreign language when the voice signal is multiplexed. Normally, the national language is set to be selected if the voice is multiplexed. The first signal processor 13 processes the left channel signal loaded with the native language applied from the third switch SW3 in a form that can be recorded on the left channel track on the high-fi tape. The second signal processor 14 processes the write channel signal containing the foreign language applied from the fourth switch SW4 in a form that can be recorded on the write channel track on the high-fi tape. The third signal processor 15 processes a signal applied from the fifth switch SW5 in a form that can be recorded on a normal track on a high-pipe tape. The signals output from the signal processing units 13, 14, and 15 are input to the matrix unit 16 and output as left and right signals according to a predetermined matrix structure.

Next, a description will be given of the case where the hi-fi VTR is a play mode for performing a voice editing function corresponding to the present invention. The control unit 11 controls each configuration to match the playback mode. The first signal processor 13 reads and reproduces the audio signal (L-CH PB FM) of the native language recorded in the high-channel tape left channel track. The second signal processor 14 reads out the audio signal (R-CH PB FM) of the foreign language recorded on the light channel track of the high-tap tape and reproduces it in an audible form. The reproduced native and foreign language audio signals are input to the matrix unit 16. The matrix unit 16 outputs the input native language and foreign language voice signals so that the listener can listen to the corresponding output channels (L, R). The native and foreign language voice signals outputted are also input to the third switch SW3 and the fourth switch SW4. The third switch SW3 receives the reproduced native language audio signal from the tape and outputs it to the fifth switch SW5 and the adder 12. As described above, when the VTR is in the recording mode, the third switch SW3 receives a native language audio signal from an external source, and the control unit 11 performs a switching operation differently for each recording mode and reproduction mode. The fourth switch SW4 receives the reproduced foreign language audio signal from the tape and outputs it to the fifth switch SW5 and the adder 12. As described above, when the VTR is in the recording mode, the fourth switch SW4 receives a foreign language audio signal from an external source, and the control unit 11 performs a different switching operation for each of the recording mode and the reproduction mode. The adder 12 obtains a sum signal S _L + S _R of two voice signals S _L and S _R input from the third switch SW3 and the fourth switch SW4. The sum signal S _L + S _R is input to the fifth switch SW5. The controller 11 controls the switching operation of the fifth switch SW5 according to the user's selection. The controller 11 controls the fifth switch SW5 to select a foreign language audio signal from the fourth switch SW4 so that the foreign language can be recorded if the native language is recorded on the normal track of the tape. On the other hand, if a foreign language is recorded on the normal track of the tape, the fifth switch SW5 is controlled to select the native language audio signal from the third switch SW3 so that the native language can be recorded. The native language or foreign language voice signal selected and output by the fifth switch SW5 is input to the third signal processor 15. The third signal processing unit 15 processes the input native language or foreign language audio signal so that the high-fi tape being reproduced can be recorded on the normal track again. The control unit 11 controls the first signal processing unit 13 and the second signal processing unit 14 to reproduce the native and foreign language audio signals recorded on the left channel track and the light channel track of the tape, respectively. The three signal processor 15 controls the reproduced native language or foreign language audio signal to be recorded on the normal track of the tape. Thus, a voice editing function for recording a voice signal different from a previously recorded voice signal is performed on the normal track of the tape.

As described above, the present invention relates to a hi-fi VTR having a voice editing function. When a high-fi tape recording both a native language and a foreign language at the same time is reproduced by a general VTR, only a native language is heard. It has the effect of listening to either foreign language or native language through voice editing.
