According to the present invention, in the high fidelity video cassette recorder (VCR), when the recording of a certain program is in progress, the recording time is expressed by voice so that the voice time information can be recorded together with the audio signal at regular time intervals. When playing back a program recorded on a videotape, audio information on the recording time can be selectively output according to the user's intention. When recording several programs on a single videotape, the voice of each program recording time is recorded. The present invention relates to an apparatus and method for outputting voice time information of a hi-fi VCR capable of giving a user convenience by allowing information to be listened to at a desired time. In general, a hi-fi VCR is a VCR capable of processing other information on a normal audio track. The hi-fi VCR focuses on a rotating head used for recording or reproducing a video signal, and uses this for recording and reproducing an audio signal. In particular, the VHS Hi-Fi VCR has two audio heads in addition to the two video heads in a rotating drum, and the FM signal is recorded by FM modulation. Is recorded. The low setting allows the audio head gap to be wider than the video head gap and magnetizes deeper into the magnetic layer of the tape. And the video signal is recorded superimposed on the previously recorded signal, but if the video signal is recorded on top of the once recorded audio signal, the video signal is recorded on the tape surface, and the audio signal remains because the magnetization power is reduced at the deep part of the tape. As a result, two types of signals coexist.

Therefore, when the audio signal is reproduced, since the audio signal surface portion is erased, the reproduction output is reduced by about 12 dB, but since FM modulation is used, the influence of noise and the like is not a problem.

In the conventional Hi-Fi VCR having the above-described configuration, when recording several programs on one video tape, an apparatus for recording the recording time of the corresponding programs can be displayed by text using OSD means. However, the method of recording the recording time using the OSD means as described above is displayed on the screen together with the video signal, so that the OSD characters are often overlaid on the video signal of the important part, thus preventing the important video signal from being viewed. Because it can act as an element, it is inconvenient to not know when each program is recorded when multiple programs are recorded when the OSD characters are deleted or viewed or when the OSD characters are not recorded from the beginning. Therefore, the present invention has been made to solve the above problems, the present invention is to record a number of programs on a single video tape to the time data indicating the recording date and time when recording for each program is in progress By automatically recording the audio information on the tape and selectively outputting it according to the user's intention during playback, the user can listen to the audio information about the program recording date and time at the desired time.

The audio signal reproduced from the signal or tape is separated into an L channel audio signal and an R channel audio signal and output to the respective audio output terminals Aout-L or Aout-R, or the audio signal reproduced from the deck unit is processed. A hi-fi audio processing unit 13 output to each of the audio output terminals Aout-L and Aout-R, and each sound separately output from the hi-fi audio processing unit or the image processing unit A signal or video signal has the deck portion (14) for the Hi-Fi VCR tape recording or reproducing the video signal and the audio signal recorded in the Hi-Fi VCR tape by using a rotary head each is provided in the same manner as conventional cases.

In addition, the recording mode or playback mode of the Hi-Fi VCR is performed according to the key control signal selected from the outside. In the recording mode, the audio information of the time data is detected and recorded automatically on the tape. In the mode, a system controller 10 for controlling an output operation of a voice signal is provided to selectively output voice information on time data reproduced from a tape according to a user's intention. To connect the key input unit 15 to which the voice time information confirmation key K1 has been added to the key matrix so that the voice time information output operation for the recording date and time can be selected according to the user's intention, the key input unit ( 15) is connected to control the operation mode of the system controller 10. In addition, when the time data control signal P1 is applied from the system controller while the real time is continuously counted and the data for the current date and time are stored by the built-in timer, time data regarding the date and time at that time is generated. There is a time data detector 16 for converting the time data supplied from the time data detector into voice time information, and the voice time information supplied from the voice information converter. In order to record on a tape by using a digital signal, a normal audio processing unit 18 is provided for outputting the data transferred to the deck unit or picked up from the deck unit as a normal audio signal. At this time, the voice information converting unit 17 compares the inputted time data with voice data for the year, month, day, hour, minute, etc. (year; 10; month; 12; time; AM and PM). Memory (24), minute; 60). Then, the switching is switched according to the voice output control signal P2 of the system controller to select one of the output of the hi-fi voice processor 13 or the output of the normal voice processor 18 to output the R-channel voice output terminal Aout-R. The audio output switching unit 19 is provided, and the audio output switching unit 19 connects the reproduction hi-fi audio processing unit 13 to the R channel audio output terminal (Aout-R) to output the hi-fi R channel audio signal. When the user presses the voice time information confirmation key K1 during playback, the qualitative voice processor 18 is connected to the R channel voice output terminal Aout-R D according to the voice output control signal P2 of the system controller. Preferably, the audio time information reproduced on the tape is output to the R channel audio output terminal Aout-R.

2 is a flowchart illustrating the operation of outputting voice time information in a hi-fi VCR according to the present invention. Key determination steps (S11-S12) for determining whether a recording key or a playback key is input by determining a key input state, The voice time information recording step (S13-S16) of automatically recording time data on a recording date and time at a predetermined time interval when the recording key is input in the key determination step (S13-S16), and the playback key in the key determination step. Is inputted to perform a reproducing operation to detect the voice time information, and when the voice time information confirmation key is input, the voice time information output step of outputting the voice time information played on the tape to the voice output terminal for a predetermined time instead of the hi-fi voice signal (S17-). S23) can be largely divided. In this case, the recording of the voice time information is a step performed when a recording key is input, and at the same time as the recording key is input, a time data control signal P1 is output to the time data detector to control time data generation for a recording date and time. To wait (S14) and to wait while determining whether the arbitrary time (in the present invention is set as an example, for example) elapses (S14), and to determine whether the recording is finished when 1 minute has elapsed Repeating the above control operation or ending the recording operation (S15-S16). In addition, the step of outputting the voice time information is a step performed when a play key is input. The step of detecting the voice time information reproduced from the tape by driving the normal voice processor at the same time as the play key is input (S17), and confirming the voice time information. Determining whether a key is input (S18) and, if the voice time information confirmation key is input, a predetermined time (in the present invention is set to 5 seconds to 10 seconds so that voice time information can be output instead of a hi-fi voice signal as an example. Switching the audio output line only to return to the original state (S19-S21), and determining whether a stop key is input during the reproducing operation to stop and end the reproducing operation of the deck ( S22-S23).

The apparatus and method for outputting voice time information in a hi-fi VCR according to an embodiment of the present invention configured as described above will be described in detail as follows. The overall operation is that during Hi-Fi VCR tape recording, the system controller sends control signals to the time data detector, detects time data such as year, month, day, hour, and minute, and outputs them to the voice information converter at one minute intervals. The audio time information is converted to the normal voice processing unit and recorded in the normal voice head. On the contrary, when the user wants to know the voice time information during playback, the system controller records the tape by pressing the voice time information confirmation key with the remote controller or VCR set. The audio signal is reproduced at the normal voice processing unit and outputs the waiting time information to the normal voice processing unit, and this signal is output through the audio output switching unit for 5-10 seconds to the Hi-Fi "R" channel.

First, the system controller 10 determines the key input state selected through the key input unit 15 (S11, S12) to determine whether the recording key is selected or the playback key is selected, and the subsequent operation according to the determination result. The key determination step of determining the branch is performed.

When the recording key is input in the key determination step (Y branch of S11), the system controller 10 continuously outputs the time data control signal P1 to the time data detection unit 16 at one minute intervals until recording is completed. (S13-S14). Accordingly, the time data detector 16 receives the control signal P1 of the system controller 10 and outputs current time data on the recording date (year, month, day) and time (hour, minute) to convert voice information. The voice information converting unit 17 converts the time data into the corresponding voice time information by comparing the time data with the memory contents already stored, and outputs the same to the normal voice processing unit 18. The deck unit 14 The voice time information recording step of recording on the tape is performed by using a normal voice head of.

On the other hand, when the playback key is input in the key determination step (Y branch of S12), the system controller 10 controls the deck unit 14 to perform the playback operation, and the voice time played back on the tape through the normal audio processing unit 18. In the state where the information is detected every minute and the output is waited for (S17), the key input unit 15 is checked again (S18). At this time, if the voice time information confirmation key (K1) is input (Y branch of S18) for 5 to 10 seconds, the voice output switch unit 19 is controlled (S19-S21) for the time set to the voice time information instead of the hi-fi voice signal. The voice output line is switched to output the voice time information outputting step of outputting the voice time information to the R channel voice output terminal Aout-R.

According to the audio time information output apparatus and method of the present invention as described above, when recording several programs on one video tape, the recording date and time are recorded by voice when recording for each program is in progress. It is useful to provide the user with convenience by allowing the user to listen to the voice information on the program recording date and time at the desired time.
