Next, the operation of the apparatus for recording / reproducing the voice multiple broadcast signal and the method according to the present invention configured as described above will be described in detail with reference to the flowchart shown in FIG. 2 and FIG.

First, referring to FIG. 2 for the recording process of the voice multiple broadcast signal, the control unit 12 of the television I controls in a state in which a control signal is waited from the control function setting unit 10 in step 80. When the signal is input, it is determined whether the control signal is a signal for specifying the voice multiple mode, and if it is determined that the control signal is not the voice multi mode designated signal, the normal playback mode is executed in step 82.

That is, the control unit 12 controls the first and second switch units 26 and 34 to be connected to the video output device (CRT device: not shown) and the audio output device (speaker: not shown). ) Is applied.

Subsequently, the control unit 12 reads the tuning data stored in the data storage unit 14 in response to the channel tuning signal of the control function setting unit 10 and applies the tuning data to the tuner 18 as the tuning signal VT. On the other hand, the OSD processing unit 16 controls to generate the OSD data of the channel number to be tuned, so that the tuner 18 of the channel corresponding to the tuning signal (VT) of the RF signal received from the antenna ANT The broadcast signal is tuned and a broadcast signal applied from the tuner 18 is applied to the video IF module 20 and the audio IF module 28.

Accordingly, the image processing unit 22 switches for a predetermined time so that the image signal converted and detected by the intermediate IF module 20 and the OSD data applied by the OSD processing unit 16 are inserted at a predetermined position on the screen. The image signal is reproduced, and the image signal processed by the image processor 22 is amplified by the image amplifier 24 and then the first output unit 26 is used to output an image output device (CRT apparatus). Is applied to be displayed on the display.

At the same time, the intermediate frequency transformed and detected voice signal by the voice IF module 28 is applied to the voice multiplexer 30. When the voice multiplexer mode is not set by the control function setting unit 10, For example, a conventional voice control process such as volume control is performed, and the voice signal processed by the voice multiple processor 30 is transmitted through the first and second switching units 34 through the voice amplifier 32. It is applied to the volume output device (speaker) and played out.

On the other hand, when the voice multiple mode is set in step 80, the control unit 12 determines whether the recording mode under the voice multiple mode is set by the control function setting unit 10 in step 84, and the result of the determination is recorded. If the mode is not set, the controller 12 proceeds to step 86 and applies a control signal VS for specifying the voice multiple mode to the voice multiplexer 30, and accordingly the voice multiplexer 30. ) Performs the separate processing of the main voice and the sub-audio included in the broadcast signal transmitted from the broadcasting station as L-channel and R-channel signals, and then the main voice and the sub-audio amplified by the voice amplifier 32 are first and second. It is applied to the audio output device (speaker) via the second switching units 26 and 34, and reproduced as signals of the L channel and the R channel.

On the other hand, if the recording is specified in the voice multiple mode as a result of the determination in step 84, the controller 12 causes the first switching unit 26 to switch to the video tape recorder II in step 88 and the The control signal CS is applied so that the second switching unit 34 switches to the audio tape recorder III side. In this state, the video tape recorder II detects the input of the video and the first audio (sub-audio) from the television I side through the first switching unit 26 (usually, detecting the synchronization signal of the video signal). The video signal recorded on the video / audio amplifier 56 in the state of driving the video tape 52 by the tape driver 50. One audio signal is controlled to be recorded on the video tape 52 via the signal recording / reading unit 54. In this state, the controller 42 calculates and displays the time recorded on the video tape 52 on the display unit 48 on the basis of the current time indicated by the time display unit 46.

The control unit 12 of the television I side controls the tape drive control unit 60 of the audio tape recorder III so that the audio tape 64 is driven by the tape drive mechanism 62. The second voice signal (main voice) routed by the switching unit 34 and applied via the voice interface 66 is amplified by the voice amplifier 68 and then by the voice recorder / reader 70. The audio tape 64 is to be recorded.

Subsequently, the control unit 12 determines whether the recording stop signal under the voice multiple mode is input by the control function setting unit 10 in step 92, and receives the video tape recorder II in step 94 when the recording stop signal is received. As the video / audio signal applied to the video / audio amplification unit 56 is blocked, the controller 42 of the video tape recorder II controls the tape driver 50 to drive the video tape 52. The tape drive control unit 60 of the audio tape recorder III controls the tape drive mechanism 62 to stop the driving of the audio tape 64 under the control of the control unit 12. As a result, recording in the voice multiple mode is terminated.

Next, the reproduction process of the first and second audio signals of the audio multiple of the video signals recorded on the video tape 52 and the audio tape 64 as described above will be described with reference to the flowchart shown in FIG. In operation 100, the controller 12 determines whether the control signal applied from the control function setting unit 10 is a signal for setting the reproduction mode, and the control signal is a signal for setting the reproduction mode. If not, the control corresponding to the control signal (e.g., channel tuning or volume control) is performed in step 102, whereas in the case of the standby control signal being a control signal for setting the playback mode, the voice multiple playback is performed in step 104. It is determined whether the mode is set.

If it is determined in step 104 that the audio multiple play mode is not set, the process proceeds to step 106 and the control corresponds to the setting state of the video / audio play mode or the audio play mode specified by the control function setting unit 10. Will be performed. That is, when the video / audio playback mode is set by the video tape recorder II in the control function setting unit 10, the control unit 12 determines the path of the first switching unit 26 in step 106. The control signal CS is applied to switch to the video tape recorder II side. After that, the control unit of the video tape recorder II controls the tape drive unit 50 to drive the video tape 52. In this state, the signal recording / reading unit 54 performs the video tape 52. The video signal and the first audio signal (sub-audio) recorded in the readout are applied to the amplifier 56, and the video signal amplified by the amplifier 56 and the first audio signal are negative. 1 is applied to the video output device and the audio output device via the switching unit 26 and reproduced. In this case, the control section 42 calculates the playback time for the video tape 52 based on the time data in the time display section 46 and displays it on the display section 48.

On the other hand, when the voice playback mode is set by the control function setting unit 10 in step 106, the control unit 12 switches the path of the second switching unit 34 to the audio tape recorder III side. On the other hand, the tape drive controller 62 of the audio tape recorder III is controlled, and thus the tape drive controller 60 controls the tape drive mechanism 62 to move the audio tape 64 in a predetermined direction. In the state where the audio tape 64 is driven in a predetermined direction, the second audio signal (main audio) recorded by the above-described process by the audio recording / reading unit 70 is read and the audio amplifier unit Amplified at 68, the amplified second audio signal is applied to the audio output device via the second switching unit 34 via the voice interface 66 and reproduced.

On the other hand, when the voice multiple playback mode is set as a result of the determination in step 104, the control unit 12, the control unit 12 in step 106 of the first switching unit 26 and the second switching unit 34 The control signal CS is applied to switch the path to the video tape recorder II and the audio tape recorder III.

Then, the control unit of the video tape recorder II controls the tape drive unit 50 to drive the video tape 52. In this state, the signal recording / reading unit 54 transmits to the video tape 52. The recorded video signal and the first audio signal (sub-audio) are read and applied to the amplifier 56, and the video signal amplified by the amplifier 56 and the first audio signal are negative. The switching unit 26 is applied to the video output device and the audio output device and reproduced. In this case, the control section 42 calculates the playback time for the video tape 52 based on the time data in the time display section 46 and displays it on the display section 48.

In addition, the controller 12 controls the tape drive controller 62 of the audio tape recorder III to drive the audio tape 64 in a predetermined direction by the tape drive mechanism 62, and the audio In the state where the tape 64 is driven in a constant direction, the second audio signal (main audio) recorded by the above-described process by the audio recording / reading unit 70 is read and amplified by the audio amplifier 68.
