The present invention relates to a voice repeating output of a VCR (Video Cassette Recorder; VCR), and in particular, a voice repeating output device suitable for enabling to repeatedly output the main voice and the sub-audio in a still picture state and It's about how.

In this regard, during the playback of a conventional conventional Hi-Fi Stereo V-Cal, if you want to watch the front part again, select the REW key and press the PLAY key when the desired part is reached. Select to watch the part you want. In addition, when the screen is paused to view a specific screen, the voice is automatically paused. At the time of reproduction, in order to hear the main voice and the sub-audio, the corresponding key may be operated.

However, in such a conventional technology, when a particular screen is stopped, only the frozen screen can be seen, and since a voice cannot be heard, a sense of presence cannot be felt.

The present invention has been made to solve the drawbacks of the prior art, the main audio and sub-audio for a certain portion of the front portion of the still picture while stopping the screen of the desired part of the hi-fi stereo V It is an object of the present invention to provide a VLC audio repeating output device and a method for repeatedly listening in turn.

In order to achieve the above object, the present invention controls a conventional function of a V-Cal in a hi-fi stereo V-C. The control unit outputs each control signal so that the audio can be repeatedly heard alternately, and the recorded video and audio of the video tape mounted therein by the corresponding signal from the control unit can be played on a normal playback or a specific screen. A deck to play only the video, a video processing unit receiving video signals reproduced from the deck and outputting a video signal for displaying the corresponding video, and a video processing unit receiving audio signals reproduced from the deck First-in, first-out voice processing unit that separates the main voice and sub-audio and outputs the main voice output of the voice processing unit. -In First-Out (FIFO) method, the main voice storage unit that outputs the current main voice signal immediately, and the negative processing output of the voice processing unit in the first-in first-out method while the current negative audio signal is output directly The voice storage unit, the sub-audio signal of the sub-audio storage and the main audio signal of the main audio storage immediately outputs the sub-audio signal and the main audio signal respectively stored by the corresponding signal from the control unit It characterized in that it comprises a switching unit for repeatedly outputting alternately.

When described in detail by the accompanying drawings an embodiment of the present invention as follows.

Referring to FIG. 1, FIG. 1 is a block diagram showing an embodiment of a VRL voice repeating output device according to the present invention. In the hi-fi stereo VP, it controls the normal function of VRT. Control unit 10 for outputting each control signal so that the main audio and sub-audio for a certain section of the front of the still screen can be repeatedly heard while stopping a specific screen, the corresponding from the control unit 10 The deck 12 which reproduces the recorded video and audio of the video tape mounted therein by the signal only for normal playback or a specific screen, and the video signal reproduced from the deck 12 are applied to process the video to process the video. The video processing unit 14 for outputting a video signal for display and the audio signal reproduced from the deck 12 are received and subjected to audio processing, and separated into main and sub audio, respectively. The main audio storage unit 18 and the audio processing unit 16 which directly output the current main audio signal while storing the output voice processing unit 16 and the main audio output of the voice processing unit 16 in a first-in first-out manner. The sub-voice storage unit 20 directly outputs the current sub-audio signal while storing the voice output in a first-in-first-out manner, the sub-audio signal of the sub-audio storage unit 20 and the main audio signal of the main audio storage unit 18. The switching unit for directly outputting and repeatedly outputting the negative audio signal and the main audio signal stored respectively in the sub-audio storage unit 20 and the main audio storage unit 18 by the corresponding signal from the control unit 10 ( 22).

Referring to FIG. 2, the present invention thus achieved is as follows.

First, in the hi-fi stereo V-C, the control unit 10 controls the normal function of the V-Cal, and alternates the main voice and the sub-audio for a predetermined section of the front part of the still picture while stopping the desired specific picture. Each control signal is output so that it can be repeatedly heard, and the deck 12 reproduces the recorded video and audio of the video tape mounted therein by the corresponding signal from the controller 10 only for normal playback or a specific screen. Play it.

Of course, the deck 12 may be able to perform operations of general VR such as recording under the control of the controller 10.

Next, the image processor 14 receives an image signal reproduced from the deck 12, processes the image, and outputs the image signal so that the image is subsequently displayed on a display device such as a monitor (not shown). In the display, the voice processor 16 receives the reproduced voice signal from the deck 12, processes the voice signal, and divides the voice signal into a main voice and a sub voice and outputs the voice signals.

The main voice storage 18 stores the main voice output of the voice processor 16 in a first-in first-out manner, and outputs the current main voice signal immediately. The current negative audio signal is immediately output while the negative audio output is stored in a first-in first-out manner, and the switching unit 22 outputs the negative audio signal of the sub-audio storage unit 20 and the main audio signal of the main audio storage unit 18. Immediately outputs the sub-audio signal and the main audio signal stored in the sub-audio storage 20 and the main audio storage 18 alternately and repeatedly by the corresponding signal from the controller 10.

Of course, whether the main voice and the sub-voice are repeatedly outputted alternately may be changed at any time by the control of the controller 10.

At this time, the control unit 10 receives a signal through a direct key operation or a remote control (Remocon) of the user to operate the deck 12 and the switching unit 22, respectively, that is, the specific operation desired by the user While stopping the screen, a time such as 20 seconds or 30 seconds can be set in consideration of the storage capacity of the main audio storage unit 18 and the sub-audio storage unit 20 in front of the frozen screen. The main voice and the sub voice for () are alternately listened to repeatedly.

2 is a flowchart illustrating an algorithm of the controller 10 of FIG.

First, in a V-CAL which is normally played back 30 by the normal function of Hi-Fi stereo V-Cal, if the voice repetition key set by the user's remote control or direct key operation is selected, the screen at that part is stopped. The main voice and the sub-audio of the previous predetermined section are alternately outputted (32, 34, 36).

Next, when the voice repetition key is selected again as described above, the normal reproducing operation is performed (38, 40).

As described above, the present invention allows each of the main audio control unit 18 and the sub audio storage unit 20 to store the main audio signal and the sub audio signal, respectively, so as to stop the screen of a specific part desired and stop it. Each main audio storage unit 18 and the sub-audio storage unit 20 for a predetermined section of the front of the screen can be repeatedly listened to the main voice and the sub-audio stored alternately, in particular, it can be effectively used in areas such as language learning It is.
