How to record and play back voice memos of Hi-Fi

The present invention relates to a method for recording and reproducing voice memos of high-fidelity VAR. In particular, a voice memo is recorded together with a bis signal during recording and playback operations on a tape through high-fidelity VREAL. The present invention relates to a method for recording and reproducing a voice memo of Hi-Five TV, which detects the vis signal and reproduces an important voice memo.

In general, a VRC system refers to a device that records video and audio signals (black and white and color) on a magnetic tape and reproduces them so that video and audio can be restored. In addition, the VR system is similar to a tape recorder in principle, but since the frequency band of the video signal is wider than that of the audio signal, the relative speed of the tape head needs to be high. For this reason, video and audio signals are recorded by rotating a head drum having four or two heads at a rate of several hundred times per second at right angles to the tape travel direction.

Then, the format in which the recorded video and audio signals are recorded on the tape is inclined at a constant angle according to the helical method as shown in FIG. 1, so that the video recording and playback head H1 is formed when scanning the entire width of the tape. The audio of the mono is recorded as the track A and the audio track head H2, the audio recording and playback head H3, and the audio playback head H4 are sequentially passed on the upper side of the track A and the video track A. Audio track B is formed.

Under the video track A, a time code is transmitted as the control erase head H5, the control write and play head H6, the address erase head H7, and the address write and play head H8 are sequentially passed. And a control track C for other control. There is also a full width erase head H9, which erases the full width of the video tape during recording.

When the video tape is high-fi, the audio signal of the pie pie is recorded in the video track A together. In other words, the high-fidelity VR system records and reproduces high fidelity recorded on a videotape and high fidelity close to the original sound and normal audio at the same time. When recording video and audio through the high-fidelity TV, the same audio signal is usually input to the hi-fi audio and the normal audio. Therefore, even during playback, hi-fi audio and normal audio are reproduced with the same audio.

On the other hand, nowadays, the use of V-seal is not only used for watching movies or music programs, but also frequently used for repetitive learning through a recording operation after recording a specific program every day, especially recorded at a specific time every day or every week. In order to clarify the distinction between each program when the program is played, the program recording date and time are recorded together when each program is recorded. Therefore, it is easy to find a program recorded on a specific date in a linearly recorded video tape, thereby improving the learning effect.

However, such a conventional VR system is used to record the date together when recording to distinguish between programs. However, even if it is necessary to add additional information according to the learning, that is, a simple memo, to the recorded program on a certain date, it is currently inserted in the VR system. When the videotape recorded or played back the program, the memo information of the program could not be additionally recorded. As a result, the learning effect was inferior because the exact contents of the current playback program were not known during the playback operation.

Therefore, in the present invention, when recording hi-fi audio and normal audio at the same time in hi-fi VRC, when the user notes important contents, the user's voice signal is recorded while recording his voice using the normal track of the audio. A specific vis signal is recorded on the recorded video tape and a memo is detected by the detection of a specific vis signal during a subsequent playback operation so that the user can play an important memo recorded in the normal track to provide additional information according to the learning. The purpose of the present invention is to provide a method of recording and playing back voice memos of Hi-Fi VRC.

In addition, the voice memo recording method of the hi-fi V-Cal of the present invention for achieving the above object is the V-Cal operation determination step of determining whether the V-CAL performs the playback mode or the recording mode, and the V-Cal operation determination As a result of the determination in step V, when the decision is performed by the playback mode or the recording mode, the memo mode setting determination step of determining whether the mode for the memo is set, and the mode for the memo is set as a result of the determination in the memo mode setting determination step. A vis signal input step of inputting a specific vis signal when judged, an external audio recording step of recording audio input from the outside to the normal track by inputting a specific vis signal in the vis signal input step, and the external audio recording step Ends recording of audio track of normal track by setting time when recording external audio from It is characterized by consisting of an external audio recording end step.

In the method for reproducing a voice memo of a hi-fi VC according to the present invention, the play mode determination step of determining whether the V-alarm is in the play mode and the non-signal signal according to the memo are determined as the play mode as a result of the play mode determination step. A vis signal detection judging step of judging whether or not is detected; a memo check display step showing that a memo voice is recorded by detecting a vis signal according to the memo as a result of the judging signal judging step; A memo check determination step of determining whether a memo check key is input after performing a display to induce a check of a memo and a memo check key set as a result of the memo check determination step are set to play a memo voice recorded on an audio normal track. During the memo voice playback step and the memo voice recorded in this memo voice playback step, The high-fi audio reproduction step of reproducing the usual hi-fi audio as the set time is reached.

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

The VR to which the present invention is applied includes a key input unit 9 for inputting a function setting signal according to playback and recording and an operation signal according to a memo mode, as shown in FIG. 2, and inputted from the key input unit 9. The microcomputer 8 controls the overall function of the system including the mode switching operation by the signal, and the information signal contained in the video tape 1 is reproduced or recorded in hi-fi according to the control signal of the microcomputer 8. When the head 2 has a plurality of mounting head drum 3 and the video tape 1 is loaded, the supply reel 4 and the winding reel 5 are driven to drive the tape 1 according to the set mode signal. A video signal processor (10) which rotates the capstan motor (6) and a video signal to reproduce or record a video signal in a video tape in contact with the head (2) in accordance with a control signal of the microcomputer (8); Video in contact with the head 2 For play or record, or a record in a pipe made of a sound signal processing unit 12 that processes an audio signal input from the external signal.

In addition, a voice memo input unit 9 for inputting a voice memo of a user is connected to the microcomputer 8.

A display 11 is connected to the video signal processor 10, and a speaker 13 is connected to the audio signal processor 12. The microcomputer 8 is also connected to a drum motor 7 for driving the head drum 3 at a prescribed rotational speed.

Next, the method of the present invention applied to the above apparatus will be described.

First, referring to the voice memo recording method according to the present invention, as shown in FIG. If it is determined in the playback operation determination step S2 that the playback operation is in progress, the process proceeds to the memo function setting determination step S3 during playback. Then, if it is determined that the memo function is set by the user as a result of judging at the memo function setting determination step (S3) during playback, the process proceeds to the audio dubbing mode step (S4). Therefore, in this audio dubbing mode step S4, the V-Cal in the reproduction operation is switched to the audio dubbing mode, and the process proceeds to the bis signal input step S7.

That is, when the video tape 1 is inserted into the deck and the play mode is set through the key input unit 9, the microcomputer 8 inputs the play mode control signal to the drum motor 7 and the capstan motor 6. At this time, the loading motor, not shown, is driven according to the mode control signal of the microcomputer 8 so as to mode switch the mode switch so that the pole base on the power transmission path of the mode switch moves the tape 1 to the head drum (3). ). Simultaneously with this operation, the capstan motor 6 also drives the take-up reel 5 of the deck at the regeneration mode speed, whereby the video tape 1 moves from the supply reel 4 to the take-up reel 5. . In addition, the drum motor 7 is also driven in synchronism with the above operation, the drum motor 7 rotates at a constant speed to rotate the head drum (3). Then, the head 2 installed in the head drum 3 is in electrical contact with the tape 1 moving to the take-up reel 5 to reproduce the information data of the selected item to reproduce the audio signal processor 12 and the video signal processor. Will be entered as (10). Therefore, the information data of the tape 1 input to the audio signal processor 12 and the video signal processor 10 is processed by a predetermined signal and then displayed to the outside through the display 11 and the speaker 13.

At this time, if the user sets the voice memo mode through a specific key through the key input unit 9, the signal is input to the microcomputer 8. Then, according to the control signal of the microcomputer 8, the audio dubbing mode is performed during the current video playback operation, where the audio dubbing mode and audio recording head and audio recording head disposed on the normal audio track in the rotating head drum 3 This means that the normal audio is newly recorded by the sequential operation of the playhead.

On the other hand, in the vis signal input step S7, a specific vis signal is recorded on the current video tape and the normal audio recording step S8 is performed. In this normal audio recording step (S8), the audio signal input from the outside is recorded in the normal audio track, and the process proceeds to the end time determination step (S9). Then, when it is determined in the end time determination step (S9) that the input time of the voice memo has ended, the process proceeds to the playback and recording operation step (S10).

That is, the specific VOS signal is recorded on the video tape as described above, and the microcomputer 8 applies a predetermined control signal to the audio signal processing unit 12. Therefore, this audio signal processing unit 12 processes the audio signal input from the voice memo input unit 14 and reproduces the audio signal processed audio through the audio erasing head and the audio recording and reproducing head in the head drum 3. Write to a normal audio track on any videotape. That is, during playback of the videotape, the user's voice memo is stored in the normal audio track for a predetermined time, and when the predetermined time has elapsed, a video reproduction operation is performed with the hi-fi audio recorded first.

On the other hand, if it is determined in the playback operation determination step (S2) that it is not determined that the playback operation is in progress, proceeds to the recording operation determination step (S5). Therefore, if it is determined in the recording operation determination step (S5) that the current recording operation is in progress, proceeds to the recording memo function setting determination step (S6). Then, if it is determined in the recording memo function determination step (S6) that the memo function is set during recording, the process proceeds to the bis signal input step (S6) to perform a loop.

If it is determined in the recording memo function determining step (S6) that the memo function is not set during recording, the process proceeds to the recording operation performing step (S11) to perform the normal recording operation and ends the loop.

On the other hand, the reproduction method of the audio information recorded on the video tape based on the audio information recording method as described above is as follows.

First, the initial state S20 in which the driving power is input and the video tape is inserted proceeds to the reproduction mode setting determination step S21. Then, if it is determined in the playback mode setting determination step S21 that the playback mode is set, the process proceeds to a hi-fi playback operation step S22. Therefore, in this hi-fi playback operation step S22, the audio is hi-fi reproduced together with the video reproduction, and the process proceeds to the voice memo service signal detection determination step S23. Accordingly, if it is determined in the voice memo vis signal detection determination step S23 that the video signal corresponding to the voice memo is detected during the video tape playback operation, the process proceeds to the voice memo confirmation display step S24. Therefore, in this voice memo confirmation display step (S24), the voice memo vis signal is detected during the reproducing operation to operate the display means for informing that there is voice information currently memorized, and proceed to the memo confirmation key input determination step (S25). As a result of the determination in the memo check key input determination step (S25), if it is determined that a key for confirming the memo is input, the voice memo normal playback step S26 is performed. Therefore, in this voice memo normal playback step (S26), the video tape being played ends the hi-fi playback operation, normal plays back audio in the section where the voice memo is recorded, and proceeds to the voice memo playback time determination step ().

On the other hand, if it is determined in the memobis signal detection determination step (S23) that the vis signal corresponding to the memo is not detected during the video tape playback operation, the process returns to the hi-fi playback operation step (S22) and repeats the loop. If it is determined that the memo key is not input as a result of the memo confirmation key input determination step (S25), the process returns to the hi-fi playback operation step (S22) and repeats the loop.

When it is determined in the voice memo playback time determining step (S27) that the reproducing operation of the memo voice has passed the set time, the process proceeds to the hi-fi reproducing return step (S28). Therefore, in this hi-fi reproduction return step (S28), the current normal reproduction operation is stopped, the reproduction operation of video and audio by the existing hi-fi signal is terminated, and the present loop ends.

If it is determined in the voice memo playback time determination step (S27) that it is determined that the playback operation of the voice memo has not elapsed the set time, the process returns to the voice memo normal playback step (S26) and continues to play the voice memo and loops. Repeat it.

As described above, in the present invention, when recording hi-fi audio and normal audio at the same time in hi-fi VRC, when the user notes important contents, the user can record his or her voice using the normal track of the audio. By recording a specific vis signal on the video tape on which the audio signal is recorded, and displaying a memo by detecting a specific vis signal in the subsequent playback operation, the user can play an important memo recorded on the normal track, thereby additionally following the learning. In addition to providing information, it is possible to easily select a specific program, thereby increasing the convenience of the operation.
